Description

Kontaktanordnung für elektrische Hochspannungsgeräte Bei elektrischen Hochspannungsgeräten, wie Transformatoren, Schaltern; Motoren o. dgl:, werden vielfach blanke Kontaktstücke verwendet, an die isolierte Leitungen angeschlossen sind. Dabei läßt es sich oft mit Rücksicht auf andere konstruktive Bedingungen nicht vermeiden, daß diese Anschlußkontaktstücke eine scharfkantige Gestalt aufweisen.Contact arrangement for electrical high-voltage devices In electrical High voltage equipment such as transformers, switches; Motors o. The like: are many Bare contact pieces are used to which insulated lines are connected. Included it can often not be avoided with regard to other constructive conditions, that these terminal contact pieces have a sharp-edged shape.

Werden nun mehrere solcher Kontakte, die auf verschiedenem Potential liegen, in verhältnismäßig geringem Abstand voneinander angeordnet, beispielsweise bei einem Regelschalter eines Anzapftransformators, oder befindet sich ein solcher Hochspannung führender Anschlußkontakt in der Nähe irgendwelcher geerdeter Teile, so besteht die Gefahr, daß Glimmentladungen auftreten. Die Isolierstrecken zwischen den einzelnen Kontakten oder zwischen diesen und den geerdeten Teilen müssen daher mit Rücksicht auf diese Glimmentladungen reichlich gewählt werden, woraus sich aber große Gesamtabmessungen des betreffenden Hochspannungsgerätes ergeben.There are now several such contacts on different potentials lie, arranged at a relatively small distance from each other, for example at a control switch of a tapping transformer, or is there one High-voltage connection contact in the vicinity of any earthed parts, so there is a risk that glow discharges occur. The insulating distances between the individual contacts or between them and the earthed parts must therefore with regard to these glow discharges are chosen in abundance, from which, however, emerges result in large overall dimensions of the high-voltage device in question.

Nach der Erfindung kann man die Nachteile dieser blanken und scharfkantigen Kontaktstücke in überaus einfacher Weise dadurch vermeiden, daß man sie mit einer Abschirmung in der Weise versieht, daß man den kräftig isolierten Anschlußleiter nicht mehr oder weniger geradlinig an den betreffenden Kontakt heranführt, sondern ihn als Abschirmung gegen ,andere Potentialträger um den zugehörigen Anschlußkontakt völlig herumführt. Durch diese erfindungsgemäße Maßnahme erhält, elektrisch gesehen, der scharfkantige Anschlußkontakt die Eigenschaften eines abgerundeten Kontaktstückes und wirkt gleichzeitig in bezug auf die Strahlung wie ein kräftig isolierter Leiter. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung dargestellt.According to the invention one can address the disadvantages of this bare and sharp-edged Avoid contact pieces in a very simple way by having them with a Shielding in such a way that the strongly insulated connecting conductor is provided does not lead to the relevant contact more or less in a straight line, but it as a shield against other potential carriers around the associated connection contact completely shows around. This measure according to the invention, seen from an electrical point of view, the sharp-edged connection contact has the properties of a rounded contact piece and at the same time acts like a strongly insulated conductor with regard to the radiation. An exemplary embodiment of the subject matter of the invention is shown in the drawing.

In dieser bedeutet a eine Leiste aus Isolierstoff; die beispielsweise einem Regelschalten eines Anzapftransformators angehört. Auf dieser Leiste .sitzen mehrere Anschlußkontaktstücke b, die mit Rücksicht auf fas mit ihnen zusammenarbeitende bewegliche Schaltstück eine scharfkantige Formgebung aufweisen.In this a means a strip made of insulating material; the example belongs to a control switching of a tap transformer. Sit on this bar several connection contact pieces b, which cooperate with them with regard to fas movable contact piece have a sharp-edged shape.

Erfindungsgemäß werden die kräftig isolierten Anzapfleiter c schneckenartig um die zugehörigen Anschlußkontaktstücke b herumgeführt, bevor sie an diese angeschlossen werden. Zweckmäßig werden ,dabei die sich gegenüberliegenden Anfänge und Enden der Leiterschleifen durch Bandagen d gegeneinander versteift.According to the invention, the strongly insulated tap ladder c are like a snail passed around the associated terminal contact pieces b before being connected to them will. It will be useful to have the opposite beginnings and ends of the Conductor loops stiffened against each other by bandages d.
