High voltage switching station

PATENT OFFICE PATENT SPECIFICATION No. 255537 class: 21c4 Int. Cl.: H 01 h expenditure day: 10. July 1967 LICENTIA PATENT VE RWALTUNGS GNIBH IN Frankfurt A.M. (GERMANY) high voltage switchgear patent of amendment to the patent No. 246,840. Announced to ll. May 1962 (A 3882/62); Priority of the registration in Germany of the 16.Mal 1,961 (L 38,979) stresses. Beginning of the patent duration: 15.November 1966. Longest possible duration: 14.September 1983. The original patent Nr.246 840 concerns a Hochspannungssehaltzelle with extendable circuit-breaker part, in which the Leistungsschalterpoie with lotmchrer Schaltstrecke in driving out direction is more himereinander arranged and dieSammehchienen in the top of the cell in the distance of the circuit-breaker poles are arranged and which cross cell in one level perpendicularly to the perpendicular Schaltstrecke. Concerning the operating front a narrow area beside this extendable construction unit, which contains the substantial lines, like air supply lines, Stromanschltlsse, Steuerund Meldeleirungen, is. The two construction units border in levels together, which lie in the driving out direction, and in these levels from a Bautell to other tlbergehenden lines are solvable connected. The narrow area can be one at least zumTefl from insulant (GleSharz) existing plate, into which the air supply lines as well as Steuerund Meldeleltungen are embedded. The upper section of the plate is bent, embraces the extendable switch part, and therein the bus bars are embedded. By this design succeeds in creating Hoehspannungssehaltzelien their overall height depending upon the Absehaltleistung of the used Leistungssehalters smaller is than 1, 5 M. Such cells can be joined now to one more or less extent me high voltage switching station, and zw. then the arrangement is so according to invention met that the cells are one above the other arranged not groove in actually well-known way next to each other and backs at jerks, but also, and dafl the whole of all in the cells enthaltenenrohrförmägenSammelsehienen each phase a catching area for the switching gases of the gleichphasigen Leistungssehalterpole forms. A Ausftlhrungsbelspiel of the invention is schematically represented in the design. The plant consists arranged Sehaltzellen 90, whose everyone, as previously mentioned, consists of an extendable and a being certain part of a set from next to each other. The being certain part is, as in the original patent suggested, plattenförmig trained and contains all pipings, power connections, Steuerund Meldeleitungen, which are embedded at least partially in casting resin. The extendable part contains the Leistungssehalterpole, which are one behind the other set up in Ausfahrriehtung and are brought by special bringing in contacts with the Sammeischienen 21 in connection. For this purpose the Leismngssehalterpole is lifted or swivelled after bringing in around a small amount. Also the connection can be made thereby that after that-brought in Gegenkontäkre at the bus bars by a small amount in the direction of the circuit-breaker poles adjust become. The mentioned cells are set up with the remark example in gröf erer number next to each other and in three floors I, II, III also one above the other. The bus bars 21 suggested in the design cross in each case one of these floors. The Sammelsehienen of each floor can be arranged into horizontal or in one for driving out direction bend-even. The Sammelsehienen is designed as pipes and serves as catching area for S chaltgase. For sound proofing absorption mechanisms are inserted, in addition in addition, filters od. to such in the pipes in suitable place. Also surveying lying valves can be so arranged in the pipes that for diverting that is kept switching gases a way of certain direction in each case. In suitable place this after phases of separation piping system is intended one ntlüftungsvorrichtung, from which the switching gases can be led into the free. In place of the Gmppierung of the cells gezelgten in the Ausführungsbeäsplel neben-und one above the other, also a Gruppiemng can be selected, with which the cells backs moved on, if necessary in several floors. In suitable place of the entire plant represented in the design construction units 22 can be intended, contain the all pipings fOr the complete system, in particular thus those pipings for the air supply and exhaust air. On rdem cells can be intended 23 in other place of the complete system, with which the inserted and driving out bases serve Leistungssehalter for it, in the individual floors angeordnemn the Sammelsehienen to couple. It is like that the whole of the cells of a floor already forms one in itself geschlosserm for plant with according to many branches and that by vorzugweise more überehiander arranged cells, alternatively one clutch can be made. Some cells represent branch fields. Within the plant special, in the same way developed cells can be present, form the separation fields for the Sammelschienenlängstremmng in suitable place. For the Dmckluftanlage a common compressed air ring circuit can be planned. For a A ulage of this kind can be used switches of arbitrary type. With small-oil-volume circuit-breakers the bus bars are appropriately shown not, as in the remark example, attached above, but down in the cells. Over with a plant of this kind also a blank field will be able to use the Zweileistungssehaltermethode planned, which contains only the Dmckluftkessel. Those the operating course course-turned side of each cell carries a metal plate, which is grounded. Here Meflinstrument¢, operating devices can be attached and if necessary also mimic diagrams. Gmndsätzlich is set up separately according to the invention the cabinet fOr the necessary protective relays from the represented switchgear. In addition, in this relay cabinet the relays can be arranged in the same grouping as the cells, the arrangement can be so met that in the relay cabinet the relays are summarized according to types and function. For driving out or other cell equipment mobile before the wave wall is planned according to kind of a stacker truck.
