Safety requirements in maintenance and repair:
● Before connecting or removing cables, turn off the protection switch of the
corresponding loop.
● Place a warning sign indicating that the switch must not be turned on at the
position where the switch resides.
● Use an electroscope of a proper voltage level to check whether the equipment
is energized and ensure that the equipment is completely powered off.
● If charged bodies are found nearby, block or wrap them with insulation plates
or insulation tapes.
● Before performing maintenance or repair, securely connect the loop to be
repaired to the main ground loop using a ground cable.
● After the maintenance or repair is complete, remove the ground cable between
the loop that has been maintained and the main ground loop.
● After the equipment stops running, wait for at least 10 minutes to ensure that
the voltage is in the safe range. Before maintenance or repair, ensure that the
transfer switch is turned to the ground position, the potential indicator is off,
the grounding switch of cabinet V in the ring main unit is turned on, and the
low-voltage cabinet is grounded.
● During maintenance, turn off the air circuit breaker on the low-voltage side
and the switch on the high-voltage side of the equipment, and place warning
signs indicating that the switches must not be turned on. If the equipment
supports the automatic mode, disable the automatic mode to ensure that the
equipment will not be powered on unexpectedly.
● Use a detergent to clean the insulation surface of the lightning arrester. After
the detergent is volatilized, evenly apply the silicon grease.
● If protection actions (such as pressure relief, gas protection, and emergency
stop) are triggered on the equipment, O&M personnel need to visit the site and
perform the following steps:
1. Set the REMOTE/LOCAL SWITCH of LV PANEL A, LV PANEL B, and ring main
