概述
General

    ZW10-12系列户外交流高压真空断路器系三相交流50Hz,户外高压开关设备,主要用于12kV农网和城网的电力系统,作为分、合负荷电流、过载电流及短路电流之用,也可用于其它类似场所。
    断路器可配隔离开关组合成组合电器;
    可配重合控制器组成重合器;
    可与FTU、RTU组成自动化配电网开关,对故障清除和隔离,自动转移供电,自动恢复供电。通过远动控制装置,与配电管理中心的DMS系统通信,可实现四遥功能。
    与智能IC卡预付费配电控制箱配置使用,可实现无费自动断电,买电自动恢复供电,满足当前供电部门对电能管理改革的需求。
     It belongs to three-phase AC 50Hz outdoor high-voltage switchear,it is used for breaking and closing load current,over load current and short-circuit current in the 12kV power system of urban and rural power net,it's also applidable for other similar locations.
     The circuit breaker can be mated with isolation to form a composie apparatus,
     Also can be mated with DRU,RTU to form automatic distrbution net swithch,it is to clear and isolate fault,transform power supply automatically,recover power supply automatically.Through telemechanism control device communicating with the DMS system, it realizes the four-remote function.
     Mated with IC card prepay distribution control box,it realizcs that power is switched off automatically without fee,and the power is switched on automati-cally if buying the power supply, therefore,it meets the requiremcnt that the power supply department reforms the electric energy control.
