Problem Of Connecting Rod Bending During High-voltage Disconnector Operation

The link bending occurred during operation hv isolator. The link bending may be caused by wear at the hinge point of hv isolator switch, increased mechanical clearance, improper preload of the operating mechanism, or low structural rigidity of high voltage electrical isolator itself. Over time, link bending not only affects the reliability of the operation, but may also lead to deviations in the closing/opening position of isolator high voltage, uneven stress on the contact surface, and increased maintenance costs of the mechanism.
