Description
Ölschalter mit Widerstand. Bei Schaltern mit Explosionskammern werden die Widerstände auf den von den Durchführungen getragenen Kammern ange ordnet, zum Zweck, eine sichere Isolierung unter -I-Vinstiger Platzausnützung zu er reichen. Bei #Sehaltern ohne Explosionskam mern ist es, um hohe Aus;
schaltleistungen zu bewälti(Yeri zweckmässig, die Unterbreehiings- stellen möglichst tief unter dem Olspiegel anzuordnen, woraus dann auch. eine entspre- ehend grössere Länge des Durchführungs- tinterteils resultiert.
Da nun diese längeren Unterteile einer bedeutend höheren Prüfspannung genügen als die übrigen Isolierteile, werden erfin dungsgemäss die -Widerstände, um eine ge drängte Bauart und hohe Isolierfähigkeit <B>zu</B> erreichen, um den Unterteil des Durch- fÜhrungsisolators herum angeordnet. Die Zeichnung zeigt sühematisch eine bei spielsweise Ausführungsform des Erfin dungsgegenstandes. Darin bedeutet a den im Schalterinnern befindlichen Durchfüh rungsunterteil, um welchen der Widerstand<B>b</B> angeordnet, und am Ende des Untei#teils; a befestigt ist. Die Hauptkontaktstellen sind mit c, die Widerstandskontakte mit c, be zeichnet.
Oil switch with resistance. In the case of switches with explosion chambers, the resistances are placed on the chambers carried by the bushings, for the purpose of ensuring safe insulation while making full use of space. In the case of # holders without explosion chambers, it is a matter of high levels;
Switching capacities to be managed (Yeri expediently to arrange the interruption points as deep as possible under the oil level, which then also results in a correspondingly greater length of the penetration tint part.
Since these longer lower parts now meet a significantly higher test voltage than the other insulating parts, according to the invention the resistors are arranged around the lower part of the bushing insulator in order to achieve a compact design and high insulation capacity. The drawing shows a schematic example of an embodiment of the invention. Here, a means the lower part of the bushing located inside the switch, around which the resistor <B> b </B> is arranged, and at the end of the lower part; a is attached. The main contact points are marked with c, the resistance contacts with c, be.
