The High-voltage Disconnector Performs Well In The Initial Stage Of Operation, But Why Does It Frequently Malfunction After One Or Two Years Of Use?

Although high voltage electrical isolator performed stably during factory inspection or initial installation and commissioning, and the closing and opening operations were relatively normal, according to on-site operation experience and feedback from multiple equipment users, after one to two years of operation, some isolator high voltage began to experience common fault problems such as operation jamming and poor contact of contacts.
