The invention concerns a phase measuring rod for a Hochspannungsfreileitung with the characteristics indicated in the generic term of the requirement 1. Phase measuring rods after the state of the art are for example well-known from the DE-20 64,622 A or DE-22 23,108 A. They are compound up from a central spacer piece, which for example after the DE-GM 75 35 613 a metallic distance sleeve can be, over finallaterally in each case to the spacer piece set long staff insulators. The latters are usually designed as plastic compound insulators, which special distributes regarding the mechanical and isolation-technical characteristics as well as the weight offer. Between the free ends of the long staff insulators and the field measuring rods between the conductor cables of the bundle leaders is steer-hurry inserted, which is more kreuzgelenkoder kardanartig trained. In addition forked connecting pieces and/or latches are freely swivelling and against lateral shift put on secured on the distance staffs of the field measuring rods. At their the connecting pieces and/or latches one carry turned away end for the distance staffs parallel to the Leitungsseilen arranged articulated bearing pins, at which the external ends of the long staff insulators are articulated stored. By the descriptive design features the phase measuring rods couple those in each case a phase of the overhead line prominent bundle leader mechanically and hold at the same time a sufficient distance between the phases. Small position changes - oscillations with low amplitude for example - are not transferred or only in small measure to the opposite bundle leader. With large and rapid deflections of a bundle leader against it the mechanical coupling is so high that the opposite bundle leader is along-expenditure-steered and the distance between two bundle leaders, necessary for a perfect enterprise of the high voltage transmission line, is thus kept. The phase measuring rods after the state of the art show the disadvantage that they can be used because of the construction of their steering hurry only for the connection by bundle leaders, that are one above the other arranged perpendicularly or with a limited side disalignment. A connection of bundle leaders running horizontal next to each other is not possible, since during a such arrangement on the inside in each case, which opposite bundle leader turned conductor cables would come into plant to the finallateral in each case long staff insulators. As way out hiefür was already suggested extending and designing as elbow the steering hurry. This means however that for the connection horizontally to each other bundle leaders arranged by perpendicular or phase measuring rods with different steering hurrying must be used. Unfavorably with the well-known phase measuring rods it is further that the forces which can be taken up by the phase measuring rods are not introduced during the transmission of bundle leader movements coaxially to the longitudinal axis of the long staff insulator in these. Thus bending moments become effective, which must to be considered during the mechanical design of the long staff insulator and to an unnecessary oversizing with according to higher weight and Materialund cost lead. Beyond that those are not while stationary the technology phase measuring rod shown usable for bundle leaders, that are compound from three or more conductor cables. Furthermore from the DD 239,086 A1 is well-known to a phase measuring rod of attachable Tragbügel. This Tragbügel serves as liaison vehicle between a phase measuring rod and a bundle leader, whereby the bundle leader at the Tragbügel is tiltable stored with one axle by means of a joint in perpendicular level. The invention is the basis the task to out-arrange and improve the well-known joint in such a way the zwischem phase measuring rod and the field measuring rod connected with the bundle leaders that most different Schwingungstypen of the conductor cables can be absorbed. This task is solved by the characteristic combination of the requirement 1. The invention-moderate phase measuring rod is by the use of a C-shaped Tragbügels as if steer-hurry between phase measuring rods and field measuring rods for the different bundling pus types and bundle leader arrangements usable. By the coaxial process the longitudinal axis of the long staff insulator and the connecting straight line between the articulated bearing axle for the field measuring rod and the fastening spot of the Tragbügels at this long staff insulator the forces arising by the mutual movements of the bundle leaders are introduced in each case coaxially into the long staff insulators of the phase measuring rod. Thus no or only small bending moments essentially affect these. They are stressed essentially only on pressure and course, whereby the long staff insulators can be dimensioned more weakly, the associated smaller weight of the phase measuring rod according to invention are in particular therefore ven advantage, because the phase measuring rods are held by the bundle leaders and thus the carrying masts of the Hochspannungsfreileitung. Appropriate one distributes arises thereby also in the dimensioning of these construction units. RK 402,128 B that well-known, C-shaped Tragbügel is according to invention trained further by a constructionally particularly simple arrangement of the Gelenkverbindung between the articulated bearing pin of the Tragbügels and the field measuring rod actually. By the use out flexible material of an existing camp block additional degrees of freedom for the possible directions of motion from field measuring rod are creative to the Tragbügel. In relation to the state of the art the field measuring rod is tiltable only around that the drag axis of the articulated bearing between Tragbügel and field measuring rod not forming articulated bearing pin. Rather the field measuring rod is additionally on the one hand tiltable around to the axis of rotation of the articulated bearing pin senkrechte vertical axis by the articulated bearing pin. On the other hand the field measuring rod is around perpendicularly to the axis of rotation and perpendicularly to the vertical axis lying horizontal axle also still tiltable. By these additional degrees of freedom it is possible to absorb for example asynchronous oscillations of the conductor cables of a bundle leader against each other. For example also whipping, Zuckund Schlängelbewegungen of the bundle leader are absorbable. The inventive organization of the articulated bearing makes the controllableness possible of the Schwingungstypen mentioned of the bundle leader and/or the conductor cables to each other and protects thus favourably the overhead line system against damage. These advantages supplement the advantages initially specified of the actually well-known Tragbügels. A further advantage of the flexible opposite a rigid camp block consists of that to the long staff insulators again smaller forces will transfer, which causes an again smaller dimensioning and a higher life span of the phase measuring rod. If the flexible camp block is designed as so-called rubber metal element (requirement 2), which exhibits movement-absorbing and form-resetting characteristics during deformation, for example transverse oscillations of the bundle leaders are absorbed also, related to the longitudinal direction, locally different amplitudes from the phase measuring rod within limits certified, however and thereby reduced. Requirement 3 concerns a constructionally particularly simple arrangement of the Gelenkverbindung between the articulated bearing pin of the Tragbügels and the field measuring rod. This constructionally simple arrangement improves additionally the adaptability of the Gelenkverbindung between the Tragbügel and the field measuring rod to special requirements. Requirement 4 concerns recesses in the camp block, which the tiltableness of the field measuring rod favours additionally. By this constructional measure the field measuring rod is tiltable around to the articulated bearing pin axis of rotation the senkrechte vertical axis and the crosswise by hiezu running horizontal axle. Due to the material properties of the camp block additionally an absorption with following resetting takes place. The arrangement of the Tragbügels according to requirement 5 is constructionally particularly simple, whereby in addition a high mechanical firmness is obtained. Requirement 6 teaches a mechanically particularly stable arrangement of the Tragbügels. The retaining block for the connection of the insulator-lateral ends of the carrying handle plates and for the attachment of the Tragbügels at the free end of the long staff insulator according to requirement 7 can be thereby part of the Tragbügels or be connected, as in requirement 8 indicated, as the externallateral insulator cap of the long staff insulator. Participates favourable, if the retaining block is trained einstückig with the insulator cap of the long staff insulator as attachment armature for the Tragbügel. The same effect as by the measures according to requirement 2 is obtained by the freely swivelling attachment of each Tragbügels at the appropriate Langstabisoiator around its longitudinal axis. The turning camp can be inserted for example between the retaining block to the attachment of the Tragbügels and the insulator cap of the long staff insulator. This further training according to requirement 9 is of advantage special at dreiOder four-being leagues bundle leaders. If such a bundle leader comes for example into transverse oscillations in the vertical level, then the individual conductor cables of connecting field measuring rods from his normal position in the vertical level one tilts. Without swivel joint between the Tragbügel and the long staff insulator on the latters a twisting moment was then expenditure-practiced, which would have to be considered again with the dimensioning of the long staff insulator. At two-being leagues bundle leaders can be done without considerable disadvantages without this swivel joint, since the motion possibility of the conductor cables is sufficient within the cable clamps and between the field measuring rod and the Tragbügel, so that such oscillations not when to the long staff insulators will transfer twisting moment. With the inclusion of a third and fourth conductor cable by the expansion of the bundle leader in the vertical level of these freedom of movement degrees it is locked whereby the swivel joint between Tragbügel and long staff insulator becomes necessary. Because of the arrangement of the Tragbügels into three partial thighs with the 11 thigh directions indicated in the requirement 10 and/or the phase measuring rod is optimally to its different operating conditions - thus the relative situation of the bundle leaders and number of conductor cables - adapted. RK 402,128 B the invention is more near described on the basis the design in different Ausführungsbeispieten.

A Hochspannungsfreileitung usually consists of several bundle leaders 1, that lead a phase of the overhead line in each case. Depending upon mechanical and electrical interpretation the BündelleJter 1 can exhibit different arrangements and number of conductor cables 2. So for example 2 existing bundle leaders 1 can horizontal beabstandet next to each other from two conductor cables arranged horizontally next to each other (Fig. 1) or vertically, laterally shifts to each other (Fig. 3) arranged its. Into the Fig. 7 and 8 is shown overhead line arrangements, which consist of two bundle leaders 1 lying horizontally next to each other ' to three each after kind of a triangle arranged conductor cables 2 standing on the head and/or of two vertically, laterally transferred one above the other arranged bundle leaders 1 " to four, transverse to the longitudinal direction conductor cables each 2, 2 ' arranged according to kind of a square. In order to prevent in the free dip of the overhead line between the carrying masts mutual affecting different phases prominent bundle leader 1.1 ', 1 " due to from oscillations due to environmental factors to, the bundle leaders 1.1 ' are in an isolated manner beabstandet, 1 " by so-called phase measuring rods 3.3 ', 3 " and mechanically gekoppeR. Into the Fig. 1 to 3 as well as 7 and 8 phase measuring rod shown 3.3 ' exhibit a central distance sleeve 4 manufactured for weight reasons from aluminum. Finallaterally in each case into this distance sleeve the cylindric Befestigungsannaturen of the two long staff insulators 6 manufactured consisting of metal from a plastic composite material intervenes. The connection between the distance sleeve 4 and the long staff insulators 6 is secured by fixing pin 7, the cross holes 8.9 in the distance sleeve 4 and/or in the Befestigungsamaturen 5 reaches through. With constant length of the long staff insulators 6 thereby a rough length adjustment of the phase measuring rods 3.3 can be obtained ' to the distance of the bundles] pus t, 1 ', 1 " by a varying of the distance sleeve length. A Feinl ngenanpassung is by three cross holes lined up 9 in the attachment armatures 5 possible, since these can be fixed thereby in different putting in depths in the distance sleeve 4. The long staff insulators 6 of conventional design exhibit isolation screens lined up 10 in longitudinal direction for the enlargement of the creep ways. At their the distance sleeve 4 turned away ends the long staff insulators 6 provided with an again metallic insulator cap 11 are as Belestigungsarmatur. Freely over swivelling the two retaining blocks 13 for in longitudinal direction for instance the C-shaped bent are, with their longitudinal centre plane essentially vertically and right-angled for conductor cable direction aligned Tragbügel 14 stored the longitudinal axis 12 of the long staff insulators 6 in each case at the insulator caps 11. These Tragbügel 14 serve 2.2 ' field measuring rods 15.15 ', 15 " and the phase measuring rods 3.3 so holding in distance ' for the articulated connection between that the individual conductor cables, 3 ". In addition the Tragbügel exhibit 14 at their outside ends one parallel to the conductor cables 2.2 ' running articulated bearing pins 16, on that the field measuring rods 15.15 ', 15 " in their emphasis (that the emphasis of the system from the conductor cables 2.2 ' and the actual field measuring rods 15.15 ', 15 " corresponds) in each case are tiltable stored. It participates important that the longitudinal axis 12 of the long staff insulators 6 and the meant connecting straight line 17 between the articulated bearing pin 16 forming the articulated bearing axle efestigungspunkt in each case and from the retaining block 13 formed E} the Tragbügels 14 at the long staff insulator 6 koa×ial run (Fig. 1,2, 3.7.8). RK 402,128 B as from the Fig. 4 and/or 5 clearly, consist the two Tragbügel 14 of two in longitudinal direction C-shaped one in each case, surface-congruent, parallel beabstandet to each other arranged plates 18.19, which are provided between their ends with a connecting prop 20 arranged in transverse direction. The C-form is realized because of the arrangement of the Tragbügel 14 and/or the plates 18.19 into three partial thighs concerning their longitudinal direction. Finallaterally at the appropriate long staff insulator 6 is fastened the attachment thighs 21 arranged transverse to its longitudinal axis 12, as the two appropriate ends of the plates 18.19 laterally onto the retaining block 13 are screwed. This attachment sschenkel 21 follows parallel with side disalignment S to the longitudinal axis 12 of the long staff insulator 6 running longitudinal thighs 22. Finally outward in an obtuse angle 23 of for instance 120° lo the camp thigh 24 arranged in addition which carries the articulated bearing pin 16 at its free end, follows this. Into the Fig. 25 connecting props functioning for the two cable clamps 26 and two as spacer pieces are compound 1 to 6 and 9 field measuring rod up shown 15 for two-bundles from two clamp bodies. The connecting props are two horizontal one above the other arranged flat irons 27, between which the frame-like mounting elements 28 the clamp body are screwed in finallaterally in each case. Centrically between the two clamp bodies 25 the articulated bearing 40 of the field measuring rod 15 is arranged, that in Fig. 6 is in detail represented. With the execution form after Fig. 6 from the two plates 18.19 of the Tragbügels 14 articulated bearing pins held 16 a Lagerbohrung 29 in the camp block 30 reaches through '. This is bolted with the two flat irons from above and/or down (screws 31). Between the articulated bearing pin 16 and the camp block 30 additionally a bearing sleeve 32 is inserted. By the span of lateral spacer rings and the camp block 30 is about centrically held 33 between the plates 18.19 between the two plates 18.19 latter. With the storage shown the field measuring rod 15 and the articulated bearing pin 16 are essentially freely tiltable. The camp block 30 ' consists thereby of a neoprene material which is flexible, works absorbing and exhibits resetting characteristics. By the arrangement in Fig. 6 of represented articulated bearing for the field measuring rod 15 a so-called rubber metal element is created, with which the field measuring rod is freely tiltable 15 not only around the articulated bearing pin 16, but also additional freedom of movement degrees opposite the Tragbügel 14 is present. In particular the field measuring rod 15 around a vertical axis by the articulated bearing pin 16 can swivel itself as well as around one transverse to this lying horizontal axle, whereby by the material properties of the camp block 30 ' an absorption and a resetting take place. These characteristics are by in Fig. 6 recesses shown and lateral 34 in the camp block 30 ' influenceable. In order to protect the long staff insulators 6 the phase measuring rod 3.3 ', 3 " against twisting moments, in each case between the insulator cap 11 and the retaining block a turning camp 44 is inserted 13 for the Tragbügel 14, whereby each Tragbügel is freely swivelling 14 around the longitudinal axis 12 of the appropriate long staff insulator 6. Into the Fig. 1 and 2 is ' shown an arrangement with horizontal parallel beabstandet to each other arranged bundle leaders 1 with in each case two conductor cables 2.2 being reported horizontally next to each other. The inside, the opposite bundle leader 1 of turned conductor cables 2 run in each case ' within the range between the Befestigungs21 and camp thigh 24 the Tragbügel 14. The longitudinal thighs 22 run in each case underneath the conductor cables 2 '. The cable clamps 26 are put on to usual design and from above on the conductor cables 2.2 '. The open sides of the two C-shaped Tragbügel 14 point thereby upward in each case. The two field measuring rods 15 can be swivelled around an angle of traverse 35 from maximally for instance 30° - rragbügeln 14, without each other turned, internal conductor cables 2 would affect ' the Tragbügel 14. In Fig. a bundle leader arrangement with two is one above the other, laterally transferred to each other arranged bundle leaders 1 with in each case two conductor cables 2.2 running horizontally next to each other ' shown 3. The phase measuring rod 3 ' is tilted arranged by the side disalignment in a vertical level arranged transverse to the leader longitudinal direction around an angle 36 of for instance 20° opposite the vertical one. The two Tragbügel 14 exhibit a against-same installation position, so that their open sides 37 point into each other turned away directions. The camp thighs 24 attack in each case from one the tilting direction 38 of the phase measuring rod 3 ' opposite angle direction at the field measuring rods 15. Also here these can swivel 35 from maximally 40° opposite the Tragbügel 14 around a large angle of traverse. In Fig. a phase measuring rod 3 is shown 7, the two bundle leaders 1 ', consisting in each case of three conductor cables 2.2 ', connects. The two bundle leaders 1 ' are horizontal beabstandet to each other arranged thereby. The field measuring rods 15 ' exhibit a star configuration, whose props 39 gather in itself with the emphasis of the field measuring rods 15 ' covering articulated bearings RK 402,128 B for the connection of the three conductor cables 2.2 '. This articulated bearing 40 is similar to in Fig. 6 camps shown developed. The two Tragbügel 14 attack with their camp thighs 24 about in each case centrically and right-angled to the meant connecting straight line between the opposite bundle leaders 1 ' turned conductor cables 2 '. Thus likewise large angles of traverse 35 possible for the field measuring rods 15 ' opposite the Tragbügeln 14 are. In Fig. 8 one above the other and laterally transferred to each other arranged bundle leaders 1 " with in each case four conductor cables 2.2 arranged in the cross section according to kind of a square ' shown is a configuration with two. The phase measuring rod 3 ' in an angle 36 of for instance 20° is arranged opposite the vertical one also here. The two Tragbügel 14 are as in Fig. 3 arranged. During the conductor cable arrangement shown the field measuring rods 15 are cross-like developed ", whereby the Tragbügel attack 14 over the articulated bearing 40 at the crossover - according to the emphasis of the Feldabstandhaltersysterns - with their camp thighs 24. Thus an installation position of the Tragbügel is given 14, with which their camp thighs 24 conductor cables 2 ' of the respective bundle leader 1 " turned between the two the opposite bundle leader 1 " are arranged in each case and attack from one the tilting direction 38 of the phase measuring rod 3 ' opposite angle direction at the field measuring rods 15 ". Again a relatively large angle of traverse for the field measuring rods 15 is possible also here by the C-form of the Tragbügel 14. Importantly with the remark examples after the Fig. 7 and 8 is the fact that the connecting straight line 17 between the articulated bearing 40 and the retaining block 13 - which fastening spot of the Tragbügels 14 at the long staff insulator 6 thus - is in each case coaxially to the longitudinal axes 12 of the long staff insulators 6 arranged. In Fig. 9 is a phase measuring rod 3 " shown, with which in place of a long staff insulator smaller dimensioned 6 three, running long staff insulators 6 ' to be used parallel to each other. These are arranged in transverse direction according to kind of a triangle. The finallateral insulator caps 11 are connected by a 2s star shaped mounting plate 41, which exhibits 42 radially which are away props 43 from a central piece. At the central piece of 42 the retaining block 13 fastened for the Tragbügel 14 is over a turning camp 44. It is to be pointed out that beside the Tragbügeln 14 to the retaining blocks 13 also the field expensive rings 45 over diagonally-radial props 46 is fastened. The field expensive rings 45 shield the area surrounded by them according to kind of a Faraday's cage, whereby corona features at the edges and corners of the long staff insulator ends are avoided.
