FZW28-12F型户外高压分界真空负荷开关,又可以叫做fzw28分界式真空负荷开关,带看门狗电器负荷开关,fzw28使用于柱上安装的场合,具有手动和电动操作功能。开关本体采用引进日本东芝公司VSP5-12,本开关为免维护负荷开关。采用真空灭弧和SF6气体作对地及相间绝缘介质。本产品符合:GB3804《高压交流负荷开关》及GBT11022《高压开关设备和控制设备标准的共用技术要求》。本说明描述了柱上真空负荷开关的结构、功能和组装方法。 FZW28(A)-12F型户外分界真空负荷开关(VSP5-12开关本体与FDR-01控制器)具备故障检测功能,保护控制功能和通讯功能,安装于10KV架空线路上,可实现自动切除单相接地故障和自动隔离相间短路故障。安装点适用于10KV配电线路用户进线的责任分界点处,也可以适用于符合要求的分支线连接处。 该智能负荷开关具备SOG功能。

SOG的定义StorageOver current Ground的缩写    

意思是具备过电流储能跳闸、接地时直接跳闸功能的、能有效防止停电区域扩大的开关器。  所谓储能跳闸就是从跳闸的准备状态,到线路失压后开关器分闸的过程。
