Description
Anordnung für Durchführungen Man ist im allgemeinen dazu übergegangen, die Durchführungsbolzen, die die Durchführung durchsetzen, besonders bei ausgegossenen Durchführungen mit einer Papierisolation zu überziehen, um die Isolatoren gegen einen Durchschlag durch die Ausfüllmasse zu schützen. Bei starker Belastung der Durchführungsbolzen, beispielsweise durch Kurzschlußstrom, tritt aber eine sehr starke Erwärmung dieser Papierisolation ein, die hierdurch Schaden leiden kann. Um diesen Nachteil zu vermeiden, wird gemäß der Erfindung die Papierisolation nicht unmittelbar über den Durchführungsbolzen geschoben oder auf diesen aufgewickelt, sondern sie wird bei leitender Verbindung mit dem Durchführungsbolzen in einer gewissen Entfernung von diesem angebracht, wobei der Durchführungsbolzen mit einer schwer die Wärme leitenden Masse umgeben ist, so daß eine unnötige Erwärmung der Papierisolation vermieden wird.Arrangement for bushings In general, one has gone over to the lead-through bolts that enforce the lead-through, especially in the case of poured-out ones Cover bushings with a paper insulation to protect against the insulators to protect a breakthrough through the filling compound. When the Bushing bolts, for example by short-circuit current, occurs but a very strong heating of this paper insulation, which can suffer damage as a result. In order to avoid this disadvantage, the paper insulation is not used according to the invention pushed directly over the lead-through bolt or wound onto it, but with a conductive connection with the lead-through bolt it is in a certain degree Removal of this attached, the grommet with a difficult the heat-conductive mass is surrounded, so that unnecessary heating of the paper insulation is avoided.
Eine der möglichen Ausführungsformen einer Durchführung gemäß der Erfindung ist in der Zeichnung dargestellt. Der Durchführungsbolzen a ist mit einer wärmeisolierenden Schicht b versehen. Auf diese ist die Papierisolation c aufgebracht, wobei eine spannungsführende :Schicht, beispielsweis:e;-ein dünner Metallzylinder d, zwischengefügt ist. Diese Teile sind umgeben von dem Außenmantel e. Der Luftzwischenraum f ist mit einer geeigneten Masse ausgegossen.One of the possible embodiments of a implementation according to the invention is shown in the drawing. The lead-through bolt a is provided with a heat-insulating layer b. The paper insulation c is applied to this, with a live: layer, for example: e; -a thin metal cylinder d, being interposed. These parts are surrounded by the outer jacket e. The air gap f is filled with a suitable compound.
