ZW8-12C intelligent outdoor high-voltage vacuum circuit breaker

ZW8-12C intelligent outdoor high-voltage vacuum breaker is a kind of intelligent breaker that exists on the basis of ZW8-12break

ZW8-12C intelligent outdoor high-voltage vacuum breaker is a kind of intelligent breaker that exists on the basis of ZW8-12breaker.This vacuum breaker has all the functions of  basic breaker.Reclosing controller makes up reclosing intelligence breaker. The basic and reclosing controller when using together  is  suitable for situation from which energy can be got easily. PT type and reclosing controller when using together is suitable for situation without energy. Intelligence breaker is suitable for radiation power supply system and ring net power supply,which helps system to  remove transient failure in toder to restore energy supply. And it can also isolate from failure forever,so   imformation automatically can be realized.

Intelligence breaker has reclosing function for 1-3 times and reclosing parameter can be setting.

Intelligence breaker has closing inrush  current controlling,flowing protection and  short quick break tri-stage mixing protection.And  the parameter can be set continuously.

Intelligene breaker has  the function of protecting low current and the parameter can be set continuously. 

Intelligence breaker can realize  cable remote control and pole wireless control.It is used for triphase power system of  AC50HZ,voltage12kv, as closing  load current.It has functions of protecting overload and short current, protecting quick break, protecting time limited and time delay.It also has the function of automatic reclosing and can equip arrester and isolating switch according to the demands of clients and etc. This intelligence breaker has power autonomously and can be controlled nearby with CY,PT connector to meet the needs of telemetry.

Using condition,
