GG-1A£®F£©Type Anti-misoperation High-Voltage Switch Cabinet

 

I. Scope of Application
The GG-1A£®F£©type anti-misoperation high-voltage switch cabinet is an indoor fixed high-voltage switch cabinet with an anti-misoperation interlocking device. It is applicable to the three-phase AC 50Hz single bus bar and single bus bar sectioning system to receive and distribute the electric energy with rated voltage 3-10kv in the network circuit.
An interlocking device is added to the cabinet on the basis of the original GG-1A type high-voltage switch cabinet. The cabinet meets the requirements of °įfive-prevention°Ī advanced by the Ministry of Energy, namely,
1. Prevent opening or closing the isolating switch with load;
2. Prevent entering into the energized compartment by accident;
3. Prevent false opening and closing of main switch;
4. Prevent hanging earth wire with power on;
5. Prevent closing the isolating switch with earth wire.
Since the cabinet is modified from the original GG-1A type high-voltage switch cabinet, the scope of application, cabinet structure, technical parameters and primary circuit scheme are basically same with those of the original cabinet.
