Countermeasures For High-voltage Disconnector Stopping During Operation

Countermeasures for midway stop:
high voltage isolator In electric operation, if there is a midway automatic stop fault, if the distance between the high voltage isolator switch contacts is small, arc discharge will be drawn for a long time, which is mostly caused by premature opening of the operating circuit and poor contact in the circuit. Solution: When pulling hv isolator, if there is a midway stop, it should be quickly opened manually. When closing the switch, if there is a midway stop and time is tight and it must be operated, the hv isolator switch should be closed manually quickly. If time permits, high voltage electrical isolator should be quickly opened, and the fault should be eliminated before operation.
Countermeasures for incomplete closing:
isolator high voltage If it cannot be fully closed during operation and the contact is poor, it will heat up during operation and endanger the safe operation of the power grid and equipment. Solution: In the event of incomplete closing or three-phase synchronization, it should be opened and closed, and repeated several times. The operation should be in accordance with the essentials and the force should be appropriate. If the three phases cannot be fully closed and synchronized, you should wear insulating gloves and use insulating rods to push the three phase contacts into place, report to your superiors and arrange a planned power outage for maintenance.
