Operation isolation switching precautions

(1) Check the circuit breaker (switch) three before the operation should be in the hierarchy position, in the absence of the belt load.

(2) The locking device for the installation of the anti-wrong operation between the knife gate, the ground cutter and the switch, must be carried out in order. If you can't operate when you are locked, you should find out if it is normal to unlock it.

Isolation switch operating mechanism control and lock the secondary loop,

(3) In operation, if the insulator is severely damaged, the isolation switch drive rod is severely damaged, and the operation is not allowed.

(4) The distant control operation should check the actual position of the isolation level, so as to avoid the transmission of the transmission mechanism in the control circuit, the rejection, rejection phenomenon, and should check whether the contacts of the separated switch is in place.

Signal knife gate:

Even if there is a misinter, it is not allowed to pull the knife. Because it will cause the negative gantry to pull the decoration, at this time, the knife should be cleaved, and the oil switch should be cut, and then pull open the blade.

Male pull knife:

At the knife lock (contact) just disconnected, the arc should be combined with the blade to avoid the arc short circuit. However, when the knife is all open, the knife is not combined.
