Description

Hochspannungskondensator, insbesondere für Meßzwecke, bei dem die eine Elektrode in ein über dem Isolierrohr angebrachtes Metallgehäuse geführt ist, welch letzteres gleichzeitig die zweite Elektrode bildet Für die Hochspannungsmessungen an Kabeln, Isolatoren u. dgl. werden häufig Kondensatoren verwendet, .die praktisch keine dielektrischen Verluste aufweisen und die zur Erhöhung der Isolierfestigkeit häufig mit Preßgas gefüllt sind. Bei den bekannten Kondensatoren befinden sich die Hochspannungselektrode und die Niederspannungselektrode frei stehend in einem Isoliergehäuse. Diese Apparate haben sich im allgemeinen in der Praxis sehr gut bewährt; sie nehmen jedoch außerordentlich große Dimensionen an, wenn, wie dies oft der Fall ist, die Kapazität groß sein soll und dabei auch die Betriebsspannung sehr hoch liegt. Dieser Umstand bringt es mit sich, daß die Kondensatoren für hohe Kapazität und hohe Spannung außerordentlich teuer werden.High-voltage capacitor, especially for measuring purposes, in which the an electrode is inserted into a metal housing attached above the insulating tube, which the latter also forms the second electrode for high voltage measurements Capacitors are often used on cables, insulators and the like, which are practical have no dielectric losses and increase the insulation strength are often filled with compressed gas. The known capacitors are High-voltage electrode and the low-voltage electrode free-standing in an insulating housing. These apparatuses have generally proven to be very effective in practice; you take however, extraordinarily large dimensions when, as is often the case, the Capacity should be large and the operating voltage is also very high. This The circumstance implies that the capacitors for high capacitance and high voltage become extraordinarily expensive.

Bei der vorliegenden Erfindung, welche die beiliegende Abbildung schematisch zeigt, ist ein Weg gewählt, der zu wirtschaftlich wesentlich günstigeren Resultaten führt. Gemäß der Erfindung erfolgt nämlich bei einem Hochspannungskondensator, insbesondere für Meßzwecke, bei dem die eine Elektrode in ein über dem Isolierrohr angebrachtes Metallgehäuse geführt ist, welch letzteres gleichzeitig die zweite Elektrode bildet, die Führung der inneren Elektrode durch einen durch den Isolator geführten frei stehenden Schaft (oder Säule). Auf dem geerdeten Fuß i ist ein Isolierrohr 2 befestigt. Durch das Isolierrohr 2 ist ein Schaft oder eine Säule 3 über das Isolierrohr 2 hinausgeführt. Am oberen Teil des Schaftes 3 befindet sich ein Belag q. des Kondensators.In the present invention, which the accompanying figure schematically shows, a path has been chosen which leads to economically much more favorable results leads. According to the invention, in particular, occurs in a high-voltage capacitor for measuring purposes, in which one electrode is placed in an over the insulating tube Metal housing is guided, the latter at the same time forming the second electrode, the guidance of the inner electrode by one passed through the insulator standing shaft (or column). An insulating tube 2 is attached to the grounded foot i. A shaft or column 3 is passed through the insulating tube 2 over the insulating tube 2 led out. A coating q is located on the upper part of the shaft 3. of the capacitor.

Letzterer ragt in ein Metallgehäuse 5 hinein, das am oberen Ende des Isolierrohres 2 befestigt ist: Die Verlegung der eigentlichen Meßkomdensators über das Isolierrohr hinaus hat den Vorteil, daß die Länge des an sich sehr teuren Isolierrohrs unabhängig ist von der Länge der Kondensatorbeläge. Außerdem ist es möglich, den Kondensatorbelägen oberhalb des Isolierrohrs einen erheblich größeren Durchmesser zu geben, so daß es gelungen ist, Kondensatoren für sehr hohe Spannungen und relativ große Kapazität in wirtschaftlicher Weise herzustellen.The latter protrudes into a metal housing 5, which is at the top of the Isolierrohres 2 is attached: The laying of the actual Meßkomdensators over the insulating tube also has the advantage that the length of the insulating tube, which is very expensive per se is independent of the length of the capacitor plates. It is also possible to use the Capacitor coatings above the insulating tube have a considerably larger diameter to give so that it has been possible to make capacitors for very high voltages and relative produce large capacity in an economical manner.

Gegenüber ähnlichen Bauarten, welche bei Hochfrequenzkondensatoren mit Vakuum als Dielektrikum bekannt geworden sind, werden erhebliche Fortschritte erzielt. Infolge der kleinen Dielektrizitätskonstante des Gases (etwa i) ist das Potentialgefälle in der nicht isolierten Säule 3 sehr hoch, so daß schon in kurzer Entfernung von der Säule eine erhebliche Potentialänderung eingetreten ist. Erst dadurch ist es möglich, auf die in der Abbildung dargestellte schlanke Form zu kommen. Würde man die Säul 3 mit einem festen Dielektrikum überziehen, wie es bei den bekannten Ausführungen der Fall ist, so würde durch dessen hohe Dielektrizitätskonstante (etwa q.) das Potentialgefälle in der Umgebung der Säule vermindert und damit bei gegebener Gesamtspannung außerhalb dieses festen Dielektrikums erhöht; dadurch müßte bei kleinen Abmessungen die überschlagsspannung des Apparates herabsinken.Compared to similar designs, which in high-frequency capacitors with vacuum having become known as a dielectric, significant advances will be made achieved. Due to the low dielectric constant of the gas (about i) this is Potential gradient in the non-isolated column 3 is very high, so that in a short time Distance from the column a significant change in potential has occurred. First this makes it possible to come up with the slim shape shown in the figure. If you would cover the column 3 with a solid dielectric, as is the case with the known Is the case, its high dielectric constant (approx q.) the potential gradient in the vicinity of the column is reduced and thus at a given Overall voltage outside this solid dielectric increased; this would have to do with small Dimensions the withstand voltage of the apparatus decrease.
