Research On Failure Mechanism And Maintenance Strategy Of Contact Spring Of High-voltage Disconnector

Due to the small cross-section of the high voltage isolator spring, the high voltage isolator switch spring is prone to corrosion and fracture, which can cause the hv isolator contact fingers to fall off. If the hv isolator switch operator is not paying attention, they can easily be hit by the contact fingers that fall off from the high voltage electrical isolator. Therefore, the isolator high voltage contact finger springs need to be regularly inspected and replaced.
