Discussion on the operation specification of power stop, power supply and grounding wire for high voltage switchgear
Guiyang switchgear remind has formed a standard specification of high voltage switchgear operation, such as its power operation should be carried out in turn according to the switch, load side switches, power supply side switches sequentially, and switching power supply is just the opposite order, but also should pay attention to prevent pulling with load knife gate。
After the operation of the high voltage switch cabinet, must check the effects, if there is a loop to standby if a task is started, check the effect after the switch must be separately by sex; other circumstances should open and close the switch check before switch to replace the actual position。
When the high voltage switchgear needs reclosing device input, the shutdown operation procedure should be switched off and input with the switch open and close. When the power supply is reused, the reclosing device should be put on the switch after being switched on. When the power fails, the reclosing device should be switched off before the switch is pulled apart. When installing the grounding wire for the high voltage switchgear, the grounding wire for dispatching management should be installed first, then the grounding line of the substation will be set up, and the grounding line will be removed in opposite order.
When installing the grounding wire in the high voltage switchgear, the grounding wire shall be installed immediately after the inspection is carried out。 If the grounding wire is installed on both sides of the switch cabinet, it is necessary to check the electricity on both sides of the switch and install the grounding wire separately。 The small Guiyang switch cabinet is here today。
