The Bearing Seizure Caused The High-voltage Disconnect Switch To Malfunction.

As a critical moving component in switch high voltage electrical isolator, the bearing's normal operation directly affects the opening and closing function of switch isolator high voltage. If the bearing seizes up, it will cause malfunction of switch high voltage isolator. This situation is common when equipment is exposed to humid or corrosive environments for extended periods. Bearings are prone to water accumulation or corrosion due to lack of proper lubrication or prolonged neglect, leading to rust on their surface. Rust increases friction, causing the bearing to seize and hindering the normal operation of the switch.
