Electrical switching device at junction point between two parts of network

Abstract

At the junction between a stationary contact (16) belonging to a common part of the network and two stationary contacts (14, 15) belonging to dividing parts of the network, such as busbars, an electrical switch comprises a single moving contact (21), the length of which allows same to enter a recess (22) in one or both of the fixed contacts, depending on the position thereof. The assembly is simplified and reduced in size.

Description

technical field [0001] The invention provides a switching device which is arranged at a junction between two parts into which a network is divided and which provides the possibility of disconnecting one or the other of the two parts. Background technique [0002] High voltage substations make it possible to distribute energy on a network and to protect said network. In the event of a failure or for maintenance, it is advantageous to disconnect an individual part of the network while leaving the other parts running normally. Circuit breakers are provided to provide a disconnection function, however, during maintenance which requires the network to be partially dismantled, it is sometimes necessary to supplement the circuit breakers by means of equipment taking additional insulation distances, especially for applications where the insulating gas is under pressure ( For example, sulfur hexafluoride SF 6 ) in facilities operating in ), because then greater vigilance is require...

Problems solved by technology

Even if there is only one connecting rod, the device still needs to have a considerable length, which prevents it from being installed in some existing networks (wherein the conductors are permanently connected between the shared part and the divided part of the network). Use as a replacement for simple switches
