Typical Problems And Solutions In The Operation Of High Voltage Disconnectors

high voltage isolator and the grounding switch cannot be mechanically operated.
1) Check whether the mechanical lock between high voltage isolator switch and the grounding switch is released.
2) Check whether the components of the mechanical transmission part of hv isolator are obviously loose, damaged, blocked, and deformed.
3) Check whether the moving and static contacts of hv isolator switch are deformed and blocked.
