Embodiment Construction

[0031] figure 1 The circuit diagram of shows a switching device 1 for interrupting a current path between points A and B. The electrical switching device 1 is preferably designed for switching a direct current driven by a direct voltage. The electrical switching device 1 has a first conventional switching position 2 and a second conventional switching position 3 . Furthermore, the switching device 1 has an unconventional switching position 4 . The non-conventional switch position 4 is arranged electrically in series between the first conventional switch position 2 and the second conventional switch position 3 . In this case, n first normal switching positions 2 and n second normal switching positions 3 are provided. For example, ten first normal switching positions 2 and ten second normal switching positions 3 can be provided. The first normal switching positions 2 are all electrically connected in series, wherein the first normal switching positions 2 on one side of the n...

Abstract

The invention relates to a switching device (1, 1a) comprising a first conventional switching point (2, 2a) and a second conventional switching point (3, 3a) which are electrically connected in series via a non-conventional switching point (4, 4a).

Description

technical field [0001] The invention relates to a switching device having a first normal switching position, a second normal switching position and an unconventional switching position. Background technique [0002] Such a switching device is known, for example, from document DE 10 2011 005 905 A1. There, a switching device is described which has gas-insulated circuit breakers and vacuum circuit breakers as conventional switching points. Electrically connected in parallel to the vacuum circuit breaker is a device for generating a reverse current, which has a thyristor. The device for generating the reverse current is designed with unconventional switching positions. [0003] The known switching devices are especially suitable for switching direct currents. In order to interrupt the direct current, a reverse current is applied to the direct current to be interrupted by means of the device for generating a reverse current in order to interrupt the direct current. [0004] ...
