ZF29 series gas insulated metal-enclosed switchgear (GIS) is a self-developed new product of our company, it has passed type test by KEMA. The equipment is applicable for power system at rated voltage of 72.5kV, 126kV and 145kV.
The product is three-phase common cabinet structure, and circuit breaker adopts self-arc extinguish principle with simple structure and low operation power. The isolating switchgear apply for three-phase position structure that has realized mechanical interlock between isolating switchgear and earthing switchgear. It can be avoid of faulty operation. The modular design is used for our products which enables flexible module to fulfill optimization design of substation.
Advantage:
Three-phase common cabinet structure and the smallest interval width is 1000mm. The structure is compact so that it can save space. Each bay can be transported entirely.
For insulation test, we add lighting impulse voltage withstand ability test except for power frequency test withstand voltage and partial discharge measurement. After all index qualified products should be deliveried, so as to ensure the quality.
The busbar and outlet wire are arranged on both side of circuit breaker. By fully use tank of circuit breaker that inspection and overhaul passageway designed on both side of each set without enter into equipment and eliminate potential accidents.
