AI Technical Summary

Problems solved by technology

A disadvantage with this known mutual locking of electrical switching devices is that additional installation space must be provided for the locking module
A locking module arranged in this way may also be susceptible to damage or contamination, so that a permanent function of the locking module cannot be ensured

Embodiment Construction

[0037] figure 1 A drive device 4 for an electrical switching device, such as a circuit breaker, in particular a compact circuit breaker, which is designed according to the construction principle according to the invention, is schematically shown in a sectional view. The drive device 4 has a Bowden cable locking module or a cable locking module or a Bowden cable (Bowdenzugverriegelungsmodul) 1 . The Bowden cable locking module 1 is integrated in the drive 4 . In particular, the Bowden cable locking module 1 is detachably fastened in a receiving groove of the housing of the drive device 4 . The Bowden cable locking module 1 has a locking element 2 which can be operatively connected to a steering drive 5 of a drive 4 . In this case, the locking element 2 of the Bowden cable locking module 1 is designed in such a way that it locks in an operative connection with the steering drive 5 of the drive 1 in one position of the electrical switching device and can be locked in another po...

Abstract

The invention relates to a drive device (4, 14, 24) used for an electric switch apparatus, especailly for a breaker. The drive device is designed at least to connect or disconnect an electric switch apparatus, wherein the drive device (4, 14, 24) comprises at least one Bowden cable locking module (1, 11, 21); the Bowden cable locking module is functionally connected with the drive device (4, 14, 24) and is designed to inter-lock an electric switch apparatus and at least one second electric switch apparatus. In addition, the invention also relates to an electric switch apparatus with the drive device (4, 14, 24), and a system comprising at least two electric switch apparatuses with the drive device (4, 14, 24).

Description

technical field [0001] The invention relates to a drive for an electrical switchgear, in particular a circuit breaker, which is designed at least for switching on or off the electrical switchgear. Furthermore, the invention relates to an electrical switching device having a drive and a system comprising at least two electrical switching devices each having a drive. Background technique [0002] The task of electrical switching devices, such as circuit breakers, is to decouple a plurality of loads from the supply network in the event of specific faults. A typical fault is the occurrence of a short-circuit current, and circuit breakers are conventionally designed to displace the switching element in the event of such a short-circuit current and thus disconnect the connection between the load and the grid. [0003] The invention relates to electrical switching devices, in particular circuit breakers in the low voltage range. "Low voltage" is typically a voltage of up to about...
