Xi'an Naidian Electric Power Equipment Co., Ltd. specializes in the production and sales hotline
The outdoor high-voltage pole-mounted vacuum circuit breaker is a new type of outdoor high-voltage switching equipment with a rated voltage of For combined load current, overload current and short circuit current. It is an ideal product to replace oil-immersed circuit breakers to achieve oil-free operation. The outer insulation is made of silicone rubber material, which has reliable insulation and strong anti-pollution ability. The vacuum circuit breaker is equipped with a spring energy storage operating mechanism, which can be operated manually, electrically and remotely. An isolation switch can be installed on the side of the circuit breaker to form an outdoor high-voltage vacuum circuit breaker-outdoor high-voltage isolation switch combination appliance, which increases the visible isolation fracture and has reliable interlocking operation. According to the user's requirements, it can be combined with the corresponding controller to form an AC high-voltage vacuum automatic recloser and automatic segmenter, and has its own operating power supply. It is an ideal equipment for realizing distribution network automation. It adopts high-voltage voltage transformer structure and can be external or built-in. It is composed of a circuit breaker and an isolation knife, called a combination circuit breaker, and can be used as a sectional switch.

Main uses
Series outdoor high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are used in three-phase power systems with AC and rated voltage to divide and combine load current, overload current and short-circuit current. The circuit breaker can be configured with a reclosing controller that can identify current characteristics and realize multiple automatic reclosing or isolation of permanent faults. It is self-contained as a power supply and becomes an intelligent circuit breaker with voltage and current signal output and controllable. It is powered by electronics and can complete the process. Three-stage composite protection of current delay, inrush delay and short-circuit quick-break.
Functional features
/Type outdoor high-voltage vacuum circuit breaker
