Detailed description
Overview
The series of outdoor high-voltage vacuum circuit breakers are outdoor high-voltage switching equipment with rated voltage three-phase AC. They are mainly used to switch the load current, overload current and short-circuit current of rural power grids, urban power grids 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.
