Factory power distribution operation specification

04-12-2019

The first electrician must have the necessary electrician knowledge, be familiar with the operating procedures, must have the electrician's operation certificate and technical boarding certificate issued by the labor bureau and the security office, and the switchgear manufacturers are familiar with the power distribution system and the power distribution room. The performance and operation methods of cabinets and other equipment, and the ability to take measures under abnormal conditions and unexpected situations; must be familiar with the types and performance of electrical wiring and electrical equipment in the distribution room, and electrical equipment such as switchgear in distribution room Performance is not fully understood and violations are prohibited.

Article 2 Electricians shall have a high degree of responsibility for their work, strictly implement the prescribed on-duty inspection system, the system of switching operations, equipment and fire equipment management systems, and access systems.

Article 3 Electricians shall regularly check the condition of cables, motors, electric consoles, switch cabinets, power distribution cabinets and other equipment on a daily basis. If problems are found during inspection, they must be dealt with in a timely manner and registered for reporting. When checking the motor temperature, first check the power and then test it with the back of the hand.

Article 4 Temporary construction electricity must comply with the prescribed temporary wiring specifications (with the provisions of temporary line for cable overhead), temporary wires that are not allowed to be unqualified, and switches that are not allowed to hang lamps, instrument tools and welding machines. And the socket, the original electrical circuit can not be modified without the consent of the factory electrician.

Article 5 The electrical equipment shall be regularly inspected and maintained according to the regulations, and the unused electrical equipment lines shall be completely removed.

Article 6 Some power outages shall be covered by auxiliary equipment, insulation tables, insulating mats and installations when the electrical body is close to 0.9 meters. It shall be not less than 0.35 meters and shall be hanged with signboards. When using power tools It is necessary to insert the plug socket three times, and it must be grounded or equipped with an earth leakage circuit breaker to protect against electric shock.

Article 7 When using a ladder, the angle between the ladder and the wall shall be 60-75 degrees. When using the ladder on the cement wall, anti-slip measures shall be taken, and some people shall hold the ladder. The escalator shall wear a cap for monitoring.

Article 8 When switching power distribution devices such as switchgear cabinets into and out of high and low voltage power distribution rooms, the doors must be locked at will; when inspecting indoor and outdoor high voltage equipment, they should wear insulated shoes and should not be close to electrified bodies and metal parts such as lightning arresters and lightning rods.

Article 9 When any conductive part of the equipment is grounded, it shall not be allowed to be close except for the rescue of the electric shock before the power is cut off. The 10KV will leave 4~8 meters away from the surrounding area, and the distance will be 2.5~4 meters below 1KV to avoid striding. Voltage damage.

Article 10 When repairing equipment, the switch and the knives shall not be pulled down with the load. When the knives are opened without the load, the electricity and discharge shall be checked, and the switch and the knives shall be hanged. Gate, someone works" signboard. When working near the transformer, you should hang the "stop, high pressure danger" sign, and the work place should be attached with the "work here" warning sign.

Article 11 When low-voltage equipment is energized, special personnel shall be provided for supervision. Wear caps, long-sleeved clothes, insulated gloves, tools with insulated handles, and work on dry insulation. Adjacent live parts are separated by an insulating plate. It is strictly forbidden to use trowels, metal rulers and brushes with metal objects. Tools such as donkeys work next to the electrified body.

Article 12 When working on the secondary circuit of a current transformer with load, it is necessary to prevent the secondary side of the current transformer from opening a high voltage. When disconnecting the secondary circuit of the current transformer, short circuit must be used to short-circuit the secondary terminal of the current transformer. Do not perform any work on the circuit and wires of the short-circuit terminal. Do not use wire to wrap. Do not disconnect the grounding point of the circuit during work; it must be guarded by special personnel, use insulated tools, and stand on the insulating mat.

Article 13 Insulating gloves shall be worn when pulling the high-pressure knife gate with the insulating rod or pulling the high-pressure knife gate and the oil switch through the transmission. When operating outdoor high-voltage equipment on rainy days, insulated boots should be worn, and switching operations are prohibited during lightning. Capacitors must be discharged one by one when operating on a capacitor circuit, and a resistive voltage class bulb must be used for discharge. Ground after discharge.

Article 14 When charging and unloading low-voltage fuses, wear protective glasses and insulating gloves, use insulating clamps if necessary, and stand on the insulating mat.

Article 15 After the electrical equipment is powered off, it shall be regarded as having electricity and shall not touch the equipment and enter the barrier before the knife is opened and the measures are taken to prevent sudden incoming calls or static electricity.

Article 16 When a fire occurs in an electrical equipment, it shall be extinguished with carbon tetrachloride, carbon dioxide fire extinguisher or 1211, dry powder fire extinguisher. It is strictly forbidden to use water to save.

Article 17 When operating the line and switch facilities, one person shall be supervised by one person for operation, and shall be provided with power failure, electricity inspection, discharge, installation of grounding wire, installation of a fence, and hanging of signboards.

Article 18 The lines of the factory area and workshops, irrelevant personnel (persons without basic knowledge of electrician) shall not be modified at will, if found to be treated
