Description

Hochspannungssicherung mit einer die eigentliche Sicherung tragenden, beweglichen Traverse In den heutigen vermaschten Hochspannungsnetzen ist die Auswechselung bzw. Prüfung einer Abschmelzsicherung, die bekanntlich zwischen Trennschalter und Transformator liegt, mit. nicht zu unterschätzenden Gefahren für die damit beauftragten Personen verbunden, da ein Pol der Sicherung auch in der Ausschaltstellung mit dem Netze verbunden bleibt. Dieser Pol kann z.` B. über den Transformator einer zweiten.,, beispielsweise örtlich weit .entfernten, parallel auf das gleiche Netz arbeitenden Speiseleitung unter Spannung kommen.High-voltage fuse with a fuse that carries the actual fuse movable traverse In today's meshed high-voltage networks the replacement or testing a fuse, which is known between the disconnector and Transformer lies, with. not to be underestimated dangers for those responsible People connected because one pole of the fuse is also in the off position with the Networks remains connected. This pole can e.g. via the transformer of a second. ,, for example, locally distant, working in parallel on the same network Feed line come under tension.

Man hat daher Einrichtungen entwickelt, bei denen der eigentliche Sicherungsteil auf einer ein- und ausschaltbaren Traverse angeordnet ist, so daß der Sicherungsteil zweipolig von den Leitungsanschlußkontakten abgehoben werden kann. Bei den bekannten Einrichtungen besteht jedoch der Nachteil, daß das richtige Einlegen der Kontaktteile der Sicherungen in die Gegenkontakte mit Schwierigkeiten verknüpft ist.One has therefore developed facilities in which the actual Fuse part is arranged on a traverse that can be switched on and off, so that the securing part can be lifted off the line connection contacts in two poles can. In the known devices, however, there is the disadvantage that the correct one Insertion of the contact parts of the fuses into the mating contacts with difficulty is linked.

Gemäß der Erfindung wird dieser Nachteil dadurch vermieden, daß die Kontakte der Sicherung in die Kontakte der sie tragenden Traverse und diese wiederum in die Anschlußkontakte der zu sichernden Leitung eingreifien.According to the invention, this disadvantage is avoided in that the Contacts of the fuse in the contacts of the traverse carrying them and these in turn intervene in the connection contacts of the line to be secured.

Die Zeichnung stellt ein Ausführungsbefspiel der Erfindung dar.The drawing represents an exemplary embodiment of the invention.

Abb. i zeigt die Draufsicht auf eine drein I'I polige Sicherung, Abb. 2 die Seitenansicht auf eine dreipolige Sicherung in eingeschaltetem Zustande, Abb. 3 die Seitenansicht einer dreipoligen Sicherung in ausgesclialtetemZustande. Der Sicherungsrahmen i trägt die drei sich gegenüberliegenden Stütz- oder Durchführungsisolatorpaare 2, deren jedes die zwei Kontaktfedern 3 zur Aufnahme der die Sicherung 4 tragenden Traverse 5 'besitzt. Die Traverse 5 ist mit Zwischenkontakten 6 versehen, in die die Messerkontakte 7 der eigentlichen Sicherung 4 eingreifen. Die Traverse 5 ist außerdem durch Porzellanfassungen 8 mit Kniehebeln 9 verbunden, deren Enden einerseits mit :einer im Rahmen i drehbar gelagerten, für alle hasen gemeinsamen Welle i o verbunden sind,' während die anderen Enden an Gestängen i i des Sicherungsrahmens i gleitend geführt sind. Die Auslage des Kniehebels 9, wie auch die der Gestänge i i (s. Abb. 3) sind derart bemessen, daß: die durch Drehung des Hebels, 13 der Welle io aus den Kontakten 3 herausgehobene Traverse 5 mit Sicherung 4 gefahrlos berührt werden kann. Diese Ausschaltung erfolgt für alle drei Phasengleichzeitig. Wenn statt der Sicherung 4 ein Trennmesser in die Kontakte 7 eingesetzt wird, erhält man einen zweipolig abschaltenden Trennschalter.Fig. I shows the top view of a three-pole fuse, Fig. 2 the side view of a three-pole fuse in the switched-on state, Fig. 3 shows the side view of a three-pole fuse in the disengaged state. Of the Fuse frame i carries the three opposing pairs of support or bushing insulators 2, each of which has the two contact springs 3 for receiving the fuse 4 supporting Traverse 5 'owns. The traverse 5 is provided with intermediate contacts 6 into which the blade contacts 7 of the actual fuse 4 engage. The traverse 5 is also connected by porcelain sockets 8 with toggle levers 9, the ends of which on the one hand with: a rotatable shaft in frame i, common to all rabbits i o are connected, 'while the other ends on linkage i i of the safety frame i are sliding. The display of the toggle lever 9, as well as that of the linkage i i (see Fig. 3) are dimensioned such that: the by turning the lever, 13 the Shaft OK from the contacts 3 lifted cross member 5 with fuse 4 safe can be touched. This deactivation takes place for all three phases at the same time. If, instead of the fuse 4, a separating knife is inserted into the contacts 7, it is obtained a two-pole disconnecting switch.
