Electrical bundle leader.

As inventors are called: Dr. Glehn. Engineers Gusto Barke and Dr. %echn. Engineer Benno 1Kengele in Vienna. For reducing the radiation losses of electrical high voltage transmission lines was suggested training the ladder as so-called federations] leaders dividing i.e. into several from each other ahstehende partial leaders. this arrangement asked that opposite also well-known Hohlseilon and such. the advantage that the partial leaders can be manufactured for their part as solid connectors from a Baustoif of good electrical conductivity. Bie Erlindung is based now on the realization that one with the practically limited Teflleiterzah! (three, four, fiinf etc.) the critical tension " federations] of a leader not at will by Abl " ücken the partial leader from each other to increase can. After more exact investigations the critical tension reaches with a Tei] was away from approximately that eight to tenfold partial leader diameter an upper border, while it bd cheerful distance of the Tel] leaders from each other down sinks. In order to increase now the efficiency the federations] of the leader, Bierden his Teflleiter with artificially increased diameter ausgeftihrt according to invention. To the part] pus the bundle leaders straight those procedures applied, which originally by the federations] leaders will thus be avoided should. Thus the partial leaders ground either from Banstoff of smaller electrically lead [Stahlalnmmiumleiter and such ähigkeit) as those of the copper manufactured or as combined ladder (or as Hohlieiter (of pipes, Itohlseile) trained. Opposite a uniform leader of artificially increased diameter these federations] leader has on the one hand the advantage of the einfaclieren production of his partial leaders, on the other hand the advantage that one can master tensions if necessary with IBM, for whom the well-known Hoblseile and such un usfi'd becomes xbar. If one divides for example a Velieiter into four usual part] pus of same Gesamtquerschnitt, then for instance the l'8 subject of the natural Leistnng of the umgeteilten leader can will fibre-carry during giinsügster spacer calculation anf the bundle leader educated from it. Over this increase in output of 80% one comes with given building material expenditure by no IE always constituted calculation of the Teilleiterahstände outside. If one increases however the Teilleiterdurehmesser under Versehlechterung of the average leads [it ähigkeit e.g. on the double then the appropriate enlargement of the Teilleiterahstände results in a reitere increase of the natural achievement to the difference of the bundle leader with unvergrößertem partial leader diameter, with which one can arrive to 7 " 3lachen up to the achievement of the undivided leader. The increase in output opposite this amounts to here thus 630°/o, thus for instance the eightfold of the effect of the usual bundle leader. Because of here apparent the arising ultiplikation of partial effects one knows from there with relatively small Durchmesservergröl already erungen the Tei] leader substantial increases in output to cause.
