Summary:
GW1 outdoor AC high voltage disconnect switch (disconnect switch for short) is used to open and close circuit with voltage but no-load 50/60Hz, 12(40.5)kV power system. It accords with standard: IEC62271-103: High voltage switches. It can b e matc hed with CS type manual mechanism to avoid error, there is no necessary to hang an earthing line. There are normal and anti-pollution two types, the anti-pollution type used in serious pollution area.
Structure feature:
This disconnect switch consists of three single pole switch, each single pole switch have same structure, frame, operating insulating,
Static contactor, blade, etc, for with earth switch, It can matched with CS operating mechanism, for no earth switch, it can matched
With CS8-5 operating mechanism accordingly.
When without circuit breaker or circuit breaker was fault, disconnect switch can opening and closing under the condition:
C/O voltage transformer which for metering,
C/O charging current which on busbar facility,
C/O power transformer no load current ( power transformer capacity should less than 750kVA).
