Xi'an high-voltage circuit breaker
Xi'an high-voltage circuit breaker
Overview
Series outdoor high-voltage vacuum circuit breakers are rated voltage three-phase AC The outdoor high-voltage switchgear is mainly used to switch the load current, overload current and short-circuit current of Henan, urban and small power systems. The overall structure of this product is a three-phase common box type three-phase vacuum arc extinguishing chamber placed in a metal box, using insulating materials for inter-phase insulation and ground insulation, with reliable performance and high insulation strength.
It is called a combination circuit breaker, which is a combination of a circuit breaker and an isolation knife. It can be used as a sectional switch or can have its own power supply, either built-in or external.
The operating mechanism of this series of products is a type spring energy storage operating mechanism, which is divided into electric and manual.
