This switch can be exchanged between three HV circuit in closing or breaking operation state , it can instead of the HV load switch of three units or HV switch cabinet which is required in the double power resource or by loop feed operating method and simplify the HV circuit .
The switch can be sorted into four position structure of bus bar line 1 power supply , bus bar line 2 power supply and breaking method , according to the transition requirement , we can operate the steering pole and handle shaft to drive the switch turning on clockwise or counter-clockwise direction freely , once operation can turn a 90°.
