产品简介
●VD4真空断路器以空气为绝缘的户内式开关设备元件，断路器符合GB／T1984、DL／T403、德国DIN VDE0670与IEC62271-100；2001及60694等标准的规定。在正常使用条件下，只要在断路器的技术参数范围内，它就可以保证安全，可靠地运行于相应电压等级的电网中。
●VD4真空断路器可在工作电流范围内进行频繁的操作或多次开断短路电流；机械寿命可高达30，000次满容量短路电流开断次数可高达100次。
●VD4真空断路器适于重合闸操作并有极高的操作可靠性与使用寿命VD4真空断路器在开关柜内的安装形式既可以是固定式，也可以是抽出式的，还可安装于框架上使用
以是抽出式的，还可安装于框架上使用。
