Description

Die Erfindung betrifft einen Spannungswandler, insbesondere für Hoch- und Mittelspannungsschaltanlagen, mit einem Magnetkern und einer auf diesem angeordneten Primär- sowie Sekundärwicklung, zwischen denen eine Isolierschicht vorgesehen ist, wobei die Primärwicklung einen Leiter aufweist, der an einem Ende an einen außen liegenden Hochspannungskontakt geführt ist und am anderen Ende eine leitende und lösbare Verbindung zum Erdpotential aufweist, die im Normalbetrieb mit dem Erdpotential verbunden ist, und wobei die Sekundärwicklung einen Leiter aufweist, dessen Enden an außenliegende Meßkontakte geführt sind.The invention relates to a voltage converter, in particular for high and medium voltage switchgear, with one Magnetic core and a primary and arranged on this Secondary winding, between which an insulating layer is provided, the primary winding having a conductor has at one end to an outside High voltage contact is performed and one at the other end has a conductive and detachable connection to earth potential, which is connected to the earth potential in normal operation, and the secondary winding has a conductor, the ends of which are guided to external measuring contacts.

Bekannte Hochspannungswandler müssen bei der Prüfung der Spannungsfestigkeit einer Schaltanlage demontiert werden, da sie sonst beschädigt werden. Das Abtrennen der Spannungswandler von der Schaltanlage verursacht einen erheblichen Montageaufwand.Known high-voltage converters must be considered when testing the Dielectric strength of a switchgear can be dismantled otherwise they will be damaged. The separation of the Voltage converter from the switchgear causes one considerable assembly effort.

Aus der DE-A-2 506 937 ist ein gattungsgemäßer Spannungswandler bekannt, bei dem ein Spulenanschluß einer Hochspannungsspule lösbar mit einem Gehäuse verbunden ist. Im Prüffall könnte dieser Spulenanschluß zwar vom Gehäuse gelöst werden, um die Hochspannungesspule über die gesamte Ausdehnung ihrer Wicklung unter Hochspannung zu setzen. Jedoch besteht in diesem Fall die Gefahr, daß am freien Spulenanschluß bei hohen Prüfspannungen Überschläge auf das Gehäuse auftreten.From DE-A-2 506 937 is a generic Known voltage converter in which a coil connection of a High-voltage coil is detachably connected to a housing. In the test case, this coil connection could be from the housing be solved to the high voltage coil over the entire Expansion of their winding under high voltage. However, in this case there is a risk that the free Coil connection with high test voltages arcing on the Housing occur.

Aufgabe der Erfindung ist es, den Montageaufwand beim Prüfen von Schaltanlagen zu verringern.The object of the invention is to reduce the assembly effort Reduce testing of switchgear.

Diese Aufgabe wird bei dem gattungsgemäßen Gegenstand dadurch gelöst, daß neben dem anderen Hochspannungskontakt auch der erdpotentialseitige Kontakt der Primärwicklung hochspannungsfest ausgebildet ist. Die erfindungsgemäße Konstruktion erlaubt es, daß zur Prüfung lediglich die erdpotentialseitige Verbindung der Primärwicklung getrennt wird. Im übrigen bleibt der Spannungswandler fest mit der Schaltanlage verbunden.This task is the generic subject solved in that next to the other high voltage contact also the contact of the primary winding on the earth potential side is designed to withstand high voltages. The invention Construction allows only the Earth potential side connection of the primary winding separated becomes. Otherwise, the voltage converter remains fixed with the Switchgear connected.

Auf dem freigelegten Kontakt kann gemäß dem Verfahrensanspruch 10 aus Sicherheitgründen eine Kappe aufgesetzt werden, die hochspannungsfest ist. Dadurch wird die Berührungssicherheit des Spannungswandlers verbessert.On the exposed contact, according to the Method claim 10 for security reasons a cap be put on, which is high voltage resistant. This will improves the contact safety of the voltage converter.

Zum einfachen und bequemen Anschließen des Spannungswandlers ist vorgesehen, daß er einen Klemmenkasten aufweist, in dem die leitende Verbindung für Erdpotential und die Enden der Sekundärwicklung auf Kontakte gelegt sind.For easy and convenient connection of the Voltage converter is provided that he Has terminal box in which the conductive connection for Earth potential and the ends of the secondary winding Contacts are established.

Der Wandler ist so aufgebaut, daß die Primärwicklung aus zwei Teilwicklungen besteht, wobei insbesondere die beiden Teilwicklungen der Primärwicklung im wesentlichen dieselben Windungszahlen aufweisen.The converter is constructed so that the primary winding is off there are two partial windings, in particular the two Partial windings of the primary winding are essentially the same Have number of turns.

Erfindungsgemäß ist die Sekundärwicklung innerhalb der Primärwicklung angeordnet und außen durch eine Isolationsschicht von der Primärwicklung getrennt, wobei vorzugsweise die Isolation eine äußere leitende Schicht aufweist, die vorzugsweise auch die beiden Teilwicklungen der Primärwicklung leitend verbindet.According to the secondary winding is within the Primary winding arranged and outside by a Isolation layer separated from the primary winding, whereby preferably the insulation is an outer conductive layer has, which preferably also the two partial windings of the primary winding.

Dadurch, daß die Isolationsschicht eine Durchschlagspannungsfestigkeit aufweist, die der Prüfspannung entspricht, wird für den Normalbetrieb die Isolationsschicht nur mit dem halben Prüfspannungspotential belastet, was zur Betriebssicherheit beiträgt.The fact that the insulation layer Dielectric strength that the Test voltage corresponds to that for normal operation Insulation layer with only half the test voltage potential burdened, which contributes to operational safety.

Eine bevorzugte Ausführungsform der Erfindung wird nachfolgend anhand einer Zeichnung beschrieben, dabei zeigt:

Figur 1
schematisch einen Vertikalschnitt durch den erfindungsgemäßen Spannungswandler.
A preferred embodiment of the invention is described below with reference to a drawing, which shows:
Figure 1
schematically shows a vertical section through the voltage converter according to the invention.

In Figur 1 bezeichnet 1 einen allseitig durch Metall gekapselten Spannungswandler. Als Metallkapselung dient das Gehäuse 2 das üblicherweise auf Erdpotential 3 liegt.In FIG. 1, 1 denotes a metal on all sides encapsulated voltage converter. That serves as metal encapsulation Housing 2 which is usually at ground potential 3.

Im Inneren des Gehäuses 2 befindet sich der eigentliche Spannungswandler. Er besteht aus einem Magnetkern 4, der von einem Leiter einer Sekundärwicklung 5 umschlossen ist. Die Enden 6 und 7 des Leiters der Sekundärwicklung sind in einen Klemmkasten 8 auf Kontakte a und n geführt.The actual one is located inside the housing 2 Voltage converter. It consists of a magnetic core 4, the is enclosed by a conductor of a secondary winding 5. The ends 6 and 7 of the conductor of the secondary winding are in a terminal box 8 out on contacts a and n.

Die Sekundärwicklung 5 wird außen von einer Isolationsschicht 9 umschlossen, die als Tragkörper einer Primärwicklung 10 dient. Der Stromfluß in den Wicklungen ist in üblicher Weise mit einem Punkt bzw. Kreuz dargstellt. Primärwicklung 10 besteht aus 2 Teilwicklungen 11 und 12, die beide dieselbe Windungszahl aufweisen und miteinander durch Leiter 13 verbunden sind. Leiter 13 kann beispielsweise auch als Metallisierung der Isolationsschicht 9 ausgebildet sein.The secondary winding 5 is outside of one Insulation layer 9 enclosed as a supporting body Primary winding 10 is used. The current flow in the windings is in the usual way with a point or cross shown. Primary winding 10 consists of 2 partial windings 11 and 12, both of which have the same number of turns and are interconnected by conductors 13. Head 13 can for example as a metallization of the Insulation layer 9 may be formed.

Ein Leiterende 14 der Primärwicklung 10 ist nach außen an den Hochspannungskontakt A und ein anderes Ende 15 des Leiters der Primärwicklung an den Hochspannungskontakt N geführt. Dieser Hochspannungskontakt N ist im Normalbetrieb mittels eines Leiters 16 in den Klemmkasten 8 geführt und dort auf Erdpotential 3 gelegt.A conductor end 14 of the primary winding 10 is on the outside the high voltage contact A and another end 15 of the Conductor of the primary winding to the high-voltage contact N guided. This high-voltage contact N is in normal operation by means of a conductor 16 in the terminal box 8 and put on earth potential 3 there.

Das Innere des Gehäuses 2 ist mittels einer Isoliermasse 18 vergossen, dadurch sind die Einbauteile festgelegt.The interior of the housing 2 is by means of an insulating compound 18 potted, this fixes the built-in parts.

Für den Fall eines Spannungstestes wird Leiter 16 von Kontakt N getrennt.In the event of a voltage test, conductor 16 of Contact N separated.

An dem Hochspannungskontakt A kann im Prüffall die volle Prüfspannung anliegen. Diese liegt dann auch an dem Hochspannungskontakt N an. Das Trennen des Spannungswandlers an Hochspannungskontakt A entfällt somit vorteilhaft. Die gesamte Schaltanlage kann also ohne großen Montageaufwand auf ihre Spannungsfestigkeit geprüft werden. The full voltage can be connected to the high-voltage contact A in the test Test voltage applied. This is also due to the High voltage contact N on. The separation of the Voltage converter at high-voltage contact A is therefore not required advantageous. The entire switchgear can therefore be large Assembly effort to be checked for their dielectric strength.
