Abstract

High-voltage, high-power fuses cannot disconnect currents less than approximately three times their rated current. Since the load interrupter switch, which is combined with the high-voltage, high-power fuse, reliably copes with currents which are less than three times the rated current of the fuse it is proposed, according to the main application P 3409957.3 to provide a high-voltage, high-power fuse having an overload device. This overload device consists of a bimetallic trip device in the circuit of the high-voltage, high-power fuse. According to the additional application, it is provided for a thermal or temperature trip device to be used as the trip device, which is inserted in the circuit or in the vicinity of the circuit of the high-voltage, high-power fuse.

Hochspannungs-Hochleistungs-SicherungHigh-voltage high-performance fuse

Die Erfindung betrifft eine Hochspannungs-Hochleistungs-Sicherung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a high-voltage, high-performance fuse according to the preamble of claim 1.

Nach der Hauptanmeldung P 34 09 957.3 ist die Hochspannungs-Hochleistungs-Sicherung mit einem Bimetallauslöser ausgestattet, welcher die Aufgabe hat, im Falle eines Überstromes einen in einer Kappe der Hochspannungs-Hochleistungs-Sicherung befindlichen Auslösestift freizugeben, der sodann einen vorgeschalteten Lasttrennschalter öffnet. Zwischen dem Bimetallauslöser und dom Auslösestift ist eine verrastende Klinke vorgesehen. Diese Klinke wird bei einem Verschwenken des Bimetalls aus der Rastposition geholt, so daß der Auslösestift, der unter Federspannung steht, in seine Auslöseposition schnellen kann. Neben dem Bimetallauslöser und der verrastenden Klinke sind jedoch noch weitcare Auslöse- und Rastelemente denkbar.According to the main application P 34 09 957.3 is the high-voltage high-performance fuse equipped with a bimetal release, which has the task of activating an overcurrent in the event of an overcurrent located in a cap of the high-voltage high-performance fuse Release the trip pin, which then opens an upstream switch-disconnector. Between the bimetal release and A latching pawl is provided for the release pin. This pawl is when the bimetal is pivoted out of the locking position fetched so that the release pin, which is under spring tension, can snap into its release position. Next to the Bimetal release and the latching pawl, however, are still far care release and latching elements conceivable.

Der Erfindung liegt daher die Aufgabe zugrunde, weitere Möglichkeiten für die Gestaltung von Auslösern und deren Verrastung aufzuzeigen, die sich in einfacher und kostengünstiger Weise in eine Hochspannungs-Hochleistungs-Sicherung einfügen lassen.The invention is therefore based on the object of further possibilities for the design of triggers and their locking to be demonstrated in a simple and inexpensive manner can be inserted into a high-voltage, high-performance fuse.

Diese Aufgabe wird erfindungsgemäß durch die in den Kennzeichen der Ansprüche 1 bis 5 angegebenen Maßnahmen gelöst·According to the invention, this object is achieved by the measures specified in the characteristics of claims 1 to 5.
