Distribution room safety regulations

1. The on-duty electrician must possess the necessary electrician knowledge, be familiar with the safety operation procedures, and be familiar with the performance and operation methods of various equipments in the power supply system and the power distribution room. And have the ability to take measures in exceptional circumstances.

2. The on-duty electrician must have a high degree of responsibility for work, strictly implement the on-duty patrol system, the work-in-vote system of the sluice gate operation system, the safety equipment and fire-fighting equipment management system, and the access system and other system regulations.

3. Individuals who are allowed to independently inspect high-voltage equipment and serve as guardians shall be approved by the head of the power department.

4. Regardless of whether the high-voltage equipment is charged or not, on-duty personnel shall not be allowed to move away or go beyond the barriers. If there is a mandatory barrier, a guardian must be present and the safety distance of the device in case of no power failure is met.

5 . When thunderstorms need to inspect outdoor high-pressure equipment, they should wear green edge shoes and should not be near the arrester and lightning rod.

6 . Investigate the power distribution device, enter and exit the high-pressure room, and must lock the door.

7. When contact with the power supply unit or user "dispatcher" to perform stop and power transmission switching operations, the person in charge on duty must review the correctness and record the contact details and contact names.

8 , power switch must be in accordance with the oil switch (or load switch, etc.). The order of the load side cutter and the bus side cutter is operated in turn.

9. The switching operation on high-voltage equipment and large-capacity low-voltage total disks must be performed by two people and a guardian who is more familiar with the equipment. The remote control or partition wall operated oil switch and switch (with oil switch interlock) can be operated by a single person.

10. Insulating gloves should be worn when using high-strength pull high-voltage switch or pull high-pressure knife and oil switch. When rain-operated outdoor high-voltage equipment, insulation boots should be worn. It is forbidden to switch over during lightning.

11. Wear protective glasses and insulating gloves when handling fuses with electricity. If necessary, use insulated clamps and stand on the insulation mat.

12. After a power outage of an electrical device, it should be considered that there is no electricity and the device must be touched before entering the fence to prevent sudden calls.

13. When power failure occurs during construction and overhaul, the on-duty personnel should perform safety measures in accordance with the requirements of the work ticket, including power outages, power inspections, installation of barriers, and hanging signage. Check with the person in charge of the worksite to confirm that there is no electricity, and confess to the nearby charged The location and precautions of the equipment, and then the two sides apply for a permit to start a work permit before they can start work.

14. At the end of the work, the staff was dismissed. The person in charge of the work explained clearly to the person in charge and checked together. After both parties had completed the work, they could remove the safety measures and resume the transmission of electricity.

Before the procedures for completing the work are not completed, the on-duty personnel are not allowed to switch on and send power to the construction equipment.

15. When the high-voltage equipment is powered off, the normal range of activities from the working staff is less than 0 and 35 meters. Distances greater than 0 , 35 m but less than 0 and 7 m must be fixed temporary barriers at a distance of not less than 0 , 35 from the live sector , otherwise power must be cut off. Those who have live parts that do not have reliable measures behind or on both sides of the staff must also be powered off.

16. When the power fails, you must cut off the power of incoming calls from each loop. Instead of just pulling the oil switch to work, the knife must be pulled open so that there is at least one distinct break point in each return. The transformer and voltage transformer must be disconnected from both the high and low voltage sides. The primary and secondary fuses of the voltage transformer must be removed. The operating switch of the oil switch should be disconnected. The operating handle of the knife lock should be locked.

17. When the inspection of electricity, it must use suitable and qualified voltage inspection electrical appliances with voltage rating. When inspecting the equipment, examine the electricity on both sides of the outlet. Before the inspection of electricity, it should be tested on electrical equipment to prove that the electroscope is good. High-voltage equipment must wear insulating gloves to inspect electricity.

18. When it is verified that the equipment has no voltage, the inspection equipment conductors shall be grounded and shorted to each other. Provide a grounding wire to all parts that may transmit power to the power-off equipment or parts that may generate induced voltage. The ground wire should be applied with bare bare copper wire. The cross-section must not be less than 25 mm2. The grounding wire must be fixed to the conductor with a special clip. The order of removal is the opposite. Insulation gloves should be used for installing and removing grounding wires. The assembly and disassembly must be done by two people. Do not allow maintenance personnel to disassemble and change the ground wire. Ground lines should be numbered and placed in a fixed location. Installation and removal of grounding cables should be well documented and clearly explained during the handover.

19. The capacitor must be discharged one by one when working on the capacitor circuit. Ground after discharge.

20. When the switch is turned on, the switch to the work place and the operation handle of the switch should be hoisted with the signboard “No closing, no work”. Hanging signs of “stopping, high voltage hazards” on both sides of the workplace and on opposite live equipment barriers and prohibited passageways.

21 , line or user maintenance requirements for power outages, on-duty personnel should take security measures, and then notify the other responsible person to start work and register. After the work is completed, it must be notified by the original responsible person to resume power transmission. It is strictly forbidden to stop or send electricity.

22. When working near charged equipment, special personnel must be supervised. The live equipment can only be carried out in the front or side of the staff or it should be powered off.

23 , when the low-voltage circuit power failure maintenance should be disconnected, remove the melting appliances. A signboard “Prohibited closing, someone working” is attached to the operation handle of the knife gate.

24 , low-voltage equipment when working with power, should be set up to monitor someone. Wear work caps, wear long-sleeved clothes, wear insulated gloves, use tools with insulated handles, and work on dry insulation. The adjacent live parts are separated by insulating sheets. It is forbidden to use trowels, metal rulers and brushes with metal objects or burrs.

25. When working on the secondary circuit of a charged current transformer, it is necessary to prevent the secondary side of the current transformer from being open to generate high voltage. When disconnecting the current loop, a short circuit must be used to short-circuit the secondary terminals of the current transformer. Do not use wires for winding. The permanent grounding point of the circuit must not be disconnected during operation. When working, there must be special person monitoring, using insulated tools, and standing on an insulating mat.

26. In the event of personal electric shock and fire accidents, the on-duty personnel should immediately disconnect the power of the relevant equipment without contact to carry out the rescue.

27. In the event of a fire in electrical equipment, carbon tetrachloride and carbon dioxide fire extinguishers should be used. When the transformer is on fire, it is only around.
