Abstract

The invention concerns a circuit breaker housing for a gas insulated switchgear (GIS) in the medium and high voltage range characterized in that it comprises at least four flanges allowing multiple common point arrangements so that conductors from different switchgear devices can be connected directly to the circuit breaker.

Description

technical field [0001] The invention relates to a compact circuit breaker for gas insulated switchgear (GIS) in the medium and high voltage range. [0002] More particularly, the present invention relates to a circuit breaker housing for a gas insulated switchgear. Background technique [0003] In GIS (Gas Insulated Switchgear), a circuit breaker, which is the main part of the rack, is capable of interrupting the power between the busbar and the feeder. In more recent designs, the circuit breaker housing has a vertical orientation and has no more than three flanges for mounting switchgear devices (such as earthing switches, busbars, current or voltage transformers) so that by means of so called Common point conductors connect them to the different connection points of the breakout chamber. The connection of three or more switchgear devices is called a common point. In the field of wind energy regarding 72.5kV GIS, the market is growing. The complete module must be integr...
