Product Details
Overview
ZCW□-72.5(126.5)/L open type combined electrical appliances are complete combined electrical appliances that use air as external insulation and SF6 gas as arc extinguishing medium. It is used for the control and protection of 72.5KV three-phase AC power transmission and distribution systems, and can also be used for connecting circuit breakers and opening and closing capacitor banks. It is suitable for urban substations, enterprise substations, and mountain substations with limited land.
Structural features
Circuit breakers, disconnectors, grounding switches, current transformers, busbars and other components are organically combined on a grounded steel structure support with a compact structure. The space it occupies is only 30%-50% of the split type, with significant features such as saving land and reducing project costs.
The entire interval is prefabricated in the factory, and all assembly and debugging are completed before leaving the factory and transported to the installation site as a whole, greatly shortening the installation cycle.
Adopting the fully verified high-performance arc extinguishing chamber and disconnector, it is basically maintenance-free and highly reliable.
The self-supporting busbar prefabricated in the factory between the intervals does not require the user to build the frame.
Flexible layout, can be used for various wiring methods.
The circuit breaker can be lowered for maintenance or replacement as a whole, and the power outage time can be shortened to less than 3 hours due to the small body failure.
