(Isolation Switch, Isolated)
Purpose: The out door high voltage disconnecting switch is the high voltage switch switch equipment of single phase AC. 50Hz. It is suitable for power system with rated voltage of 10kV, acted as making and breaking the power supply under the circumstances of with voltage and no load.
The disconnecting switch is adopts insulated hook rod to operate.



同樣是開關, 只是功能與需求不同而已。

任何開關有載(大電流)斷電好危險，我建議用Circuit Breaker。

本人只能解答上述兩條問題.

load break switch 是可以在有負載的情況下, 將電源切斷. 即是當機械在運行時可把電源關閉.
disconnecting switch 是 不 可以在有負載的情況下, 將電源切斷. 即是當機械在運行時 不 可把電源關閉, 是需要等無載的情況下, 才可把電源關閉.
