斷路器 負荷開關 隔離開關的區別

發布日期：2022-10-25 點擊率：100

斷路器、負荷開關、隔離開關都是用來閉合與切斷電路的電器,但它們在電路中所起的作用是不同的.其中：斷路器可以切斷負荷電流和短路電流；負荷開關只可切斷負荷電流,短路電流是由熔斷器來切斷的；隔離開關則不能切斷負荷電流,更不能切斷短路電流,只用來切斷電壓或允許的小電流.

隔離開關——只能開斷和接通系統空載電流，并且作為主接線系統明顯斷開點，在檢修過程中作為系統明顯斷開點。

負荷開關——可以開斷和接通系統正常負載電流，但不能分斷系統故障電流。

斷路器——除了可以開斷和接通系統的正常負載電流，還可以開斷和接通系統的故障和短路電流。
