2.2 Inspection of High-voltage Equipment

2.2. 1 The on-duty personnel and off-duty personnel who are allowed to patrol high-voltage equipment alone with the approval of enterprise leaders are not allowed to do other work or move or cross obstacles when patrolling high-voltage equipment.

2.2.2 In thunderstorm weather, when it is necessary to patrol outdoor high-voltage equipment, insulating boots should be worn, and lightning arresters and lightning rods are not allowed.

2.2.3 When the high-voltage equipment is grounded, it shall not be close to the fault point within 4m indoors and 8m outdoors. Personnel entering the above range must wear insulating boots and gloves when touching the shell and structure of the equipment.

2.2.4 Patrol the power distribution equipment, and lock the door when entering and leaving the high-pressure room.

2.2.5 There should be at least three keys to the high-pressure room, which shall be kept by the power distribution personnel on duty and handed over according to the value. One copy is for emergency use, the other is for the personnel on duty, and the others can be lent to the personnel and work leaders who are allowed to inspect the high-voltage equipment independently, but they must be registered and signed and returned on the same day.

2.3 pour brake operation

2.3. 1 switching operation must be carried out according to the orders of the on-duty dispatcher or the person in charge on duty, and it is repeated correctly. Commands should be issued accurately and clearly, using normal operating terms and dual names of equipment, namely equipment name and number. The sender should exchange names with the recipient before giving an order by telephone. The dispatcher on duty should record the whole process of issuing orders (including repeated orders from the other party) and listen to the report of orders. The switching operation shall be completed by the operator (see Appendix A). When a single person is on duty, the operator shall communicate the operation ticket to the attendant by telephone, and the attendant shall fill in the operation ticket according to the communication and repeat it correctly, and fill in the name of the operator at the signature of the "guardian".

Each operation ticket can only fill in one operation task.

2.3.2 Power cut-off switch operation must be carried out in the order of circuit breaker (switch)-load side isolating switch (circuit breaker)-bus side isolating switch (circuit breaker), and the order of power transmission and closing operation is opposite. Strictly prevent the circuit breaker from closing with load.

In order to prevent misoperation, high-voltage electrical equipment should be equipped with locking devices to prevent misoperation (in a few special cases, mechanical locks can be installed with the approval of higher authorities). Unlocking devices (including keys) of locking devices shall be properly kept and used according to regulations, and shall not be misused.
