Improper Coordination Between The Closing Limit Switch Of The High-voltage Disconnector And The Motor Caused Operational Malfunction.

Improper coordination between the closing limit switch of the hv isolator switch conductive rod and the motor can lead to malfunction of the high voltage electrical isolator operation. When the closing limit switch mechanism of the isolator high voltage conductive rod is not adjusted properly or structural errors accumulate, and there is a deviation in the matching of the stroke, rotation direction and torque with the motor drive system, although the motor starts, the conductive rod may not have reached or has exceeded the ideal position, resulting in the main knife switch not being fully closed or the spring contact not acting in time.
