• 断路器负荷开关隔离开关都用在什么地方??
• 
  
• 
  
• 断路器、负荷开关、隔离开关的区别：
•   断路器由于有操作机构，能够进行遥控操作及自动切断负荷电流和故障电流，
•   隔离开关只能手动操作切断正常电流，但是有明显的断开点。
•   负荷开关的作用相当于：断路器+隔离开关，但通断能力不如断路器。
• 正常情况下：高压上用断路器+隔离开关配合着用，但由于某些线路的负载不是很大、不太重要，考虑到经济性，一般会用负荷开关代替断路器+隔离开关（一般是10KV，6KV的系统）。

The breaker load switch disconnectors are in place??




Circuit breakers, load switches, disconnectors difference:
   The circuit breaker operating mechanism, capable ofremote operation and automatically cut off load current and faultcurrent,
   Isolation switch only manual operation to cut off thenormal current, but there is a significant disconnect point.
   Load switch acts: the breaker + isolation switch, butbreaking capacity than circuit breakers.
Under normal circumstances: the high pressure circuit breaker +isolation switch with the use, but because of certain line load isnot less important, taking into account the economic, general loadswitch instead of a circuit breaker + isolation switch (generally10KV , 6KV system).
