Abstract
Description
"Hochspannungsteiler""High voltage divider"
Die Erfindung betrifft einen Hochspannungsteiler, welcher aus einem oder mehreren Hochspannungswiderständen und einem oder mehreren Hochspaunungskondensatoren besteht.The invention relates to a high voltage divider, which consists of a or more high voltage resistors and one or more high voltage capacitors consists.
Derartige Ohmsch-kapazitive Spannungsteiler werden in der Hochspannungstechnik anstelle der herkömmlichen induktiven oder kapazitiven Spannungswandler dort eingesetzt, wo insbesondere größere Bandbreiten derziübertragenden Meßspannungen hinsichtlich ihrer Frequenz erforderlich sind. Dies ist z.B. in Gleichspannungsanlagen oder in ganz bestimmten Wechselspannungsanlagen der Fall.Such ohmic-capacitive voltage dividers are used in high voltage technology used instead of conventional inductive or capacitive voltage converters, where in particular larger bandwidths of the transmitted measurement voltages with regard to their frequency are required. This is e.g. in DC systems or in very specific AC systems are the case.
Die bekannten Hochspannungsteiler bestehen aus einzelnen Komponenten, nämlich Hochspannungswiderständen und -kondensatoren, die für sich unabhängige Elemente darstellen und entweder nebeneinander oder koaxial ineinander angeordnet sind.The well-known high voltage dividers consist of individual components, namely, high voltage resistors and capacitors, which are independent elements represent and are arranged either side by side or coaxially one inside the other.
Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Hochspannungsteiler der eingangs genannten Art dahingehend zu verbessern, daß dieser entweder kleinere Abmessungen besitzt als die bekannten Spannungsteiler, oder aber bei gleichen Abmessungen in bezug auf seine elektrischen Werte sowie der Einflußacglichkeit äußerer Einwirkungen verbessert ist.On the basis of this prior art, the object of the invention is to be found based on improving a high-voltage divider of the type mentioned at the outset, that this either has smaller dimensions than the known voltage dividers, or with the same dimensions in terms of its electrical values and the Influence of external influences is improved.
Gemaß der Erfindung wird dies dadurch erreicht, daß der bzw.According to the invention this is achieved in that the or
die Winderstände und der bzw. die Kondensatoren eine Baueinheit bilden, derart, daß der aktive Teil des bzw. der Kondensatoren von dem bzw. den Widerständen umschlossen ist, welcher bzw. welche ein Gehäuse für den bzw. die Kondensatoren bilden. Auf diese Weise ergibt sich eine in sicht geschlossene Baueinheit, wobei eine Verkleinerung der Abmessungen sowohl in radialer als auch in axialer Richtung erzielt wird, da das sonst für den Kondensator erforderliche Gehäuse in Fortfall kommt.the wind turbines and the capacitor (s) form a unit, such that the active part of the capacitor (s) is separated from the resistor (s) is enclosed, which or which a housing for the capacitor or capacitors form. This results in a unit that is closed in view, wherein a reduction in dimensions in both the radial and axial directions is achieved, since the housing otherwise required for the capacitor is no longer required comes.
Als Widerstand kann ein in Gießharz eingebetteter Feindrahtwiderstand in Hohlzylinderbauweise dienen, jedoch ist es auch möglich, daß als Widerstand ein Metallfilm, eine leitfähige Auflage od.dgl. auf einem Trägenshr od.dgl. aus Keramik oder Kunststoff Verwendung findet.A fine wire resistor embedded in cast resin can be used as a resistor serve in hollow cylinder construction, but it is also possible that a resistance Metal film, a conductive pad or the like. on a carrier or the like. made of ceramic or plastic is used.
Für eine Freiluftaufstellung sind sowohl der bzw. die Widerstande als auch der bzw. die Kondensatoren in einem gemeinsamen Porzellanüberwurf angeordnet, wobei diese von einem gasförmigen oder flüssigen Isolierstoff umgeben sind.Both the resistor (s) are for outdoor installation as well as the capacitor (s) arranged in a common porcelain cover, these are surrounded by a gaseous or liquid insulating material.
Ein Ausfihrungsbeispiel der Erfindung ist an Hand der Zeichnung naher erläutert, welche eine geschnittene Ansicht eines Eochspannungsteilers für Freiluftaufstellung zeigt.An exemplary embodiment of the invention is closer to the drawing which is a sectional view of a high voltage divider for outdoor installation shows.
Ilit 1 ist der Zylinder des Widerstands bezeichnet, auf den das Widerstandsmaterial 2 aufgebracht ist. In den Zylinder 1 des Widerstandes ist der aktive Teil 3 des Kondensators, das sind die Kondensatorwickel, eingebracht. Die einzelnen, den aktiven Teil 3 bildenden Kondensatorwickel sind mit einer Tränkmasse 4 vergossen.Ilit 1 is called the cylinder of the resistor on which the resistor material 2 is applied. In cylinder 1 of the Resistance is the active one Part 3 of the capacitor, these are the capacitor windings, introduced. The single ones, The capacitor windings forming the active part 3 are encapsulated with an impregnating compound 4.
Die Baueinheit,bestehend aus Zylinder 1 des Widerstandes mit aufgebrachtem Wickelmaterial 2 einerseits und dem aktiven Teil 3 in Form von Kondensatorwickeln, ist in dem Porzellanüberwurf 5 angeordnet, und zwar unter Zwischenfügung eines flüssigen oder gasförmigen Isoliermittels 6.The structural unit consisting of cylinder 1 of the resistor with applied Winding material 2 on the one hand and the active part 3 in the form of capacitor windings, is arranged in the porcelain cover 5, with the interposition of a liquid or gaseous insulating agent 6.
Die in den Porzellanüberwurf 5 hineinragende Durchführung ist mit 7 bezeichnet.The penetration protruding into the porcelain cover 5 is with 7 designated.
