When the high voltage isolating switch needs a grounding switch
Inconvenient to install the ground wire, outlet isolation must be ground switch, maintenance ground
Outlet isolation must be ground switch, maintenance ground
The grounding switch is arranged on the side of the disconnector on both sides of the circuit breaker, and only serves as the grounding on both sides when the circuit breaker is overhauled.
And the rapid grounding switch is arranged in the outlet circuit outlet switch on the side of the line, it has two roles:
1 opening and closing parallel overhead lines due to electrostatic induction generated by the capacitor current and electromagnetic induction to produce inductor current;
2 When the cabinet inside the insulator phenomenon of creepage or shell internal arc, the rapid grounding switch main circuit fast grounding, the use of circuit breaker to remove the fault current.
