product information
Product name: ZW8-12/630-20 outdoor high voltage vacuum circuit breaker
Category: high voltage components
Product introduction: The use of vacuum interrupter, air insulation, and electric spring operating mechanism make the product have strong arc extinguishing ability, high short-circuit breaking times, no fire and explosion hazard, convenient operation, excellent performance and strong practicability The product.
Overview of ZW8-12/630-20 outdoor high voltage vacuum circuit breaker
Employing a vacuum interrupter, air insulation, and an electric spring operating mechanism, the product has strong arc extinguishing capability, high short-circuit breaking times, no fire and explosion hazard, and convenient operation. It is a product with excellent performance and strong practicability.
The overall structure of this product adopts a three-phase common box type, with casing in and out of the line, dry air in the box, and an electric spring restless mechanism arranged on the side of the box, which can be used reliably under severe environmental conditions.
The vacuum arc extinguishing of this product adopts a ceramic shell, a cup-shaped longitudinal magnetic field contact structure, and a copper contact contact material, which has excellent short-circuit current capability of opening and closing.
The product is small in size, light in weight, and beautiful in appearance. The main technical parameterscompact in design, and the outlet conductive rod is filled with silicone rubber, which can adapt to harsh weather conditions and dirty environments.
Application of ZW8-12/630-20 outdoor high voltage vacuum circuit breaker
The ZW8-12/630-20 outdoor high voltage vacuum circuit breaker is an AC 50Hz three-phase power system, which is mainly used to break and close the 10KV load current, no-load current and short-circuit current of the urban and urban areas. It can also be used in rural areas. The sub-switches of power grids and small power systems are the updated products of the area network and the oil-free agricultural industry.
