Product Description

ZN8-24Q/75X210mm Epoxy Resin Support Insulator with Switchgear



First, use the electric car. Before the grounding switch, pull the circuit breaker car out of the cabinet, then push into the electric check car, the circuit grounding switch after checking that there is no voltage.


Second, open the door. When the circuit breaker is in the test position and the charged display device detects that the line has no voltage, turn on the door and check that there is no voltage, then close the ground switch.



Third, depending on the line side electric display of the role of locking device. As long as the line side electric display latching device indicates no power, latching open, the operation of the grounding switch.


Method A large amount of operation, equivalent to no electric car power outage operation, only bus and grounding operation, the use of special electric car and ground hand car. Method 2 is adopted by some power departments, the operation procedure is complicated.


Methods The third method is to use a more common way. When the circuit breaker is in the test position, the grounding switch can only be met if the circuit side has no electricity and the electric display device is electrically and normally, and the locked electromagnet is electrically and normally. Any failure or loss of power in a live display device or locked electromagnet will not be able to close the gate. At present, there are no accidents of electrically connected ground switch due to locking fault of electric display device. When the charged display sensor fails or breaks, it is reflected through the indicator light on the charged display.
