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.
