Description

Elektrischer Kondensator, insbesondere für Hochspannung, mit blind in geschichteter Isolation (insbesondere Glimmerschichten) verlegten metallischen Belegungen Die Erfindung betrifft einen elektrischen Kondensator, insbesondere für Hochspannung, mit blind in geschichteter Isolation verlegten metallischen Belegungen. Die geschichtete Isolation kann insbesondere aus Gliininerschichten bestehen.Electrical capacitor, especially for high voltage, with blind Metallic layers laid in layered insulation (especially layers of mica) Assignments The invention relates to an electrical capacitor, in particular for High voltage, with blind metallic coverings laid in layered insulation. The layered insulation can in particular consist of glinine layers.

Es ist möglich, an die Endbelegungen solcher Kondensatoren hohe Spannungen zu legen, ohne daß ein Durchbruch der einzelnen Dielektrikumsschichten eintritt.It is possible to apply high voltages to the end pinouts of such capacitors to lay without a breakdown of the individual dielectric layers occurs.

Es besteht jedoch die Möglichkeit, daß bei solchen Kondensatoren zwischen den gleich Elektroden wirkenden Endbelegungen unmittelbar ü'berschläge durch Luft über den Kriechweg, den die Ränder der zwischen diesen Belegungen befindlichen Glimmerschichten bilden, selbst bei der normalen Betriebsspannung auftreten.However, there is the possibility that with such capacitors between the end coatings, which act like electrodes, are directly flashed over by air via the creepage distance that the edges of the mica layers located between these coverings occur even at normal operating voltage.

Uni dieses zu verhindern und zugleich aus der Möglichkeit des Überschlages den Nutzen zu ziehen, daß der überschlag bei überspannungen ähnlich einer Funkenstrecke zur Sicherung des Kondensators gegen Durchschlag wirkt, sind die über die Belegungen vorspringenden Ränder der Glimmerschichten zwischen den an Spannung liegenden Endbelegungen derart bemessen, daß der Luftüberschlagsweg zwischen den Endbelegungen quer zu diesen Rändern bei normaler Betriebsspannung nicht, bei überspannungen jedoch früher durchbrochen wird als der Kondensatorkörper.Uni to prevent this and at the same time from the possibility of rollover to take advantage of the fact that the flashover in the event of overvoltages is similar to a spark gap to protect the capacitor against breakdown acts are those on the assignments protruding edges of the mica layers between the stressed end coatings dimensioned such that the air flashover path between the end coverings is transverse to these Edges not with normal operating voltage, but broken earlier with overvoltages is called the capacitor body.

Somit wird ein elektrischer Kondensator gemäß der Erfindung bei normaler Betriebsspannung weder durch- noch überschlagen, bei erhöhten Spannungen jedoch eher überals durchschlagen.Thus, an electrical capacitor according to the invention is normal Operating voltage neither crossover nor flashover, but with increased voltages rather than break through.
