Description

1. Description
Solid insulated switch is the core of solid insulated ring main switchgear. The switch is designed to integrate vacuum breaker or load switch, disconnector and earthing switch. The structure is compact which includes front side and back side. The front side is operation mechanism, the backside is primary part. Solid insulated switch can be different functional units with switchgear as a module, multiple modules has same structure, same operation.

2. Technical Feature

---- It is the core of solid-insulated switchgear.

---- Including C unit (load break switch), V unit (circuit breaker) & F unit (fuse load break switch).

---- Operating mechanism is at the front side and primary circuit is at the backside. Easily for operation, debug and test.

---- Busbar is at the top side. Easily for assembly if extending more units at left/right side.

---- As an independent component, it can be assembled to be different unit of the switchgear.
