Embodiment Construction

[0024] figure 1 A circuit breaker system 2 is shown in , which on the one hand has a drive system 8 which jointly drives two different circuit breaker units 4 and 6 . The drive system 8 here includes a drive unit 9 and a crankshaft 10 . In this refinement, crankshaft 10 is mounted, for example, on two crankshaft bearings 34 and performs a unidirectional rotational movement along arrow 20 . In this case, the crankshaft 10 has two cranks 12 and 14 which each have different crank strokes 18 and 16 . The term "crank 12" is also understood here to mean a pair of cranks 12 and 12' or 14 and 14' between which a crank pin 24 is arranged. The crankpin 24 extends here parallel to the axis of rotation 26 of the crankshaft 10 . During the rotational movement 20 , the crank pin 24 here describes a circular movement about an axis of rotation 26 . Slide bearings 28 are in turn connected to the crank pin 24 , these slide bearings being in connection with pushrods 30 . A further slide bea...

Abstract

The invention relates to a current interrupter system comprising a series arrangement of at least two interrupter units (4, 6), wherein at least one interrupter unit (4, 6) from amongst said interrupter units is a vacuum tube, and the at least two interrupter units (4, 6) are mechanically connected to a drive system (8), wherein the drive system (8) comprises a drive assembly (9). The invention is distinguished in that the drive system further has a drive shaft which, as a crank shaft (10), is equipped with at least two cranks (12, 14), wherein the at least two cranks (12, 14) have two crank strokes (16, 18) of different magnitudes.

Description

technical field [0001] The invention relates to a circuit breaker system according to the preamble of claim 1 . Background technique [0002] When using vacuum interrupters for high-voltage applications, it is often economically more advantageous to connect two or more vacuum interrupters in series in order to achieve the required withstand voltage. In this series connection, due to the structure, it is necessary to simultaneously switch vacuum switching tubes of different structures. For this purpose, each switching tube is usually equipped with its own driver or its own drive system, wherein the drive systems are synchronized with one another. Similar challenges arise when vacuum interrupters are connected in parallel with gas lines for different applications. In order to switch the two circuit breaker units synchronously, different drives are also required in each case here. However, when using two vacuum tubes connected in series or when connecting vacuum tubes and ga...
