FN5户内高压负荷开关的结构特点

2014-1-8 19:30:05点击:
松川电器有限公司制造的FN5户内高压负荷开关是一种功能介于高压断路器和高压隔离开关之间的电器,高压负荷开关常与高压熔断器串联配合使用;用于控制电力变压器。高压负荷开关具有简单的灭弧装置,因为能通断一定的负荷电流和过负荷电流。但是它不能断开短路电流,所以它一般与高压熔断器串联使用,借助熔断器来进行短路保护。
    FN5户内高压负荷开关其功能在规定的使用条件下,FN5户内高压负荷开关可以接通和断开一定容量的空载变压器(室内315KVA,室外500KVA);可以接通和断开一定长度的空载架空线路(室内5KM,室外10KM);FN5户内高压负荷开关可以接通和断开一定长度的空载电缆线路。
   FN5户内高压负荷开关 特点 :A、可以隔离电源,有明显的断开点,多用于固定式高压设备。  B、没有灭弧装置,在合闸状态下可以通过正常工作电流和短路电路。  C、严禁带负荷接通和断开电路,常与高压断路器串连使用。
