Switch module for electrical switchgear, particularly medium voltage switchgear, has housing placed in three-position switch and power circuit-breaker, and is filled with dielectric liquid

摘要

The switch module (10) has a housing (11), which are placed in a three-position switch and power circuit-breaker, and is filled with a dielectric liquid (27). The housing consists of an insulant. The metallic contact parts (20,21,23,) have a three-position switch and a power circuit-breaker, which are at a distance to the housing. The dielectric liquid is present in the area formed by the distance.
