Impact Of Interruption Of The Limit Switch Casting On The High-voltage Disconnector

The cast iron limit switches of the mechanism were broken, preventing the high voltage isolator switch from starting and stopping properly, seriously affecting the stability of the power system and increasing the maintenance costs of the hv isolator. Over long-term use, some cast iron limit switches of the hv isolator switch broke due to material problems or external impact. Common faults manifested as slow switch operation and incomplete power outages.
