Switch for use in disconnector assembly for average or high power distribution station, has elastic units arranged in part of sealed casing in support between fixed part and mobile contact, so that units compress and store elastic energy

摘要

The switch has a displacement unit (40) removing a movable contact (8) from a fixed electrode (2) and arranged at interior of a sealed casing (1). Insulated electric material elastic units i.e. helical spring (28), are arranged in a part of the sealed casing in support between a fixed part of the switch and a mobile contact, so that the elastic units compress and store the elastic energy for displacing an interior part (8.2) of the mobile contact in direction of the fixed contact when the elastic energy is released.
