Combined with the actual work, talk about how to do a good job of electrical safety Essay
A. Operation system 1. Handover system Handover work must be carried out seriously and conscientiously. Shift handover personnel should be strictly in accordance with the provisions of the handover procedures, the specific content and requirements are as follows. (1) The shift handover personnel shall fill in the records in detail and do a good job in environmental sanitation; in case of operation or work tasks, they shall take the initiative to make preparations for the end of the shift. (2) The shift handover personnel shall give a detailed introduction to the following situations: 1. the operation mode of the equipment under their jurisdiction, changes in the situation of repair, equipment defects, accident handling, notices from superiors and other related matters; 2. whether the tools and instruments, spare parts, keys, etc., are complete and intact. (3) The person who takes over the shift shall listen carefully to the content of the handover and check whether the analog drawing board and the field operation mode are consistent. When the handover is completed, both parties shall sign in the handover record book. (4) During the shift handover, reverse gate operation and license work should be avoided as much as possible. When an accident or abnormal operation occurs during the handover, the handover shall be stopped immediately, and in principle, the handover personnel shall be responsible for dealing with the accident, and the receiver shall take the initiative to assist in dealing with the accident. When the accident processing ends, then continue to handle the handover procedures. (5) In case of drunkenness or insanity of the person who takes over the shift, the person who takes over the shift should refuse to take over the shift and report to the superior to make appropriate arrangements. 2. Inspection system In order to grasp and monitor the operating condition of the equipment, and to find out the abnormalities and defects in time, the operating and standby equipment should be inspected on a regular and special basis, and should be revised and improved continuously in practice. (1) Inspection period. Someone on duty substation inspection every hour, unmanned substation inspection every four hours at least once, workshop substation inspection every shift. Special inspections as needed. (2) Regular inspection program. (1) whether the oil level of the oil injection equipment is appropriate, whether the oil color is clear, there is no leakage. (2) Porcelain insulators have no broken and discharge phenomenon. 3)Whether there is any overheating phenomenon in each connection point. (4) Whether the sound and temperature of transformer and rotating motor are normal. (5) Whether the cooling device of the transformer operates normally. 6)Whether there is any abnormal sound of capacitor and whether there is deformation and expansion of shell. (7) Whether there is oil leakage in the terminal box of power cable. (8) Whether various signal indications are normal, and whether the position of circuit breakers and disconnecting switches in the secondary circuit is correct. (9) Relay protection and automatic device pressure plate position is correct. (10) Whether the meter indication is normal, whether the pointer is bent, jamming phenomenon; whether the meter stops or backward phenomenon. (11) Whether the DC bus voltage and float charge current are appropriate. (12) whether the liquid level of the battery is appropriate, whether the color of the pole plate is normal, whether there is salt, bending, fracture, blistering and local short-circuit phenomenon. (13) equipment defects have no development. (3) Special inspection program. (1) Before the arrival of gale, check the surrounding debris to prevent debris from blowing on the equipment; when the wind is gusty, pay attention to whether the distance between phases and to the ground is too small after the wind deviation of the outdoor soft conductor. (2) after lightning, check the porcelain insulation with or without traces of discharge, lightning arrester, lightning rod discharge, lightning counter action. (3) In fog, rain, snow and other weather, should pay attention to observe the porcelain insulation discharge. (4) When heavy load, check the contacts and joints for overheating. (5) When abnormal operation occurs, check the voltage, current and relay protection action. (6) lights out at night patrol, check the porcelain insulation with or without discharge flash phenomenon, connection point with or without overheating red phenomenon. (4) patrol should comply with the safety regulations. (1) inspection of high-voltage power distribution unit should generally be two people together, after the examination and approval by the unit leader of the personnel allowed to inspect the high-voltage equipment alone. When inspecting the power distribution device and entering or leaving the high-voltage room, the door must be closed at hand. (2) When inspecting the high-voltage equipment, it is not allowed to move or cross the fence, and it is not allowed to carry out any operation; if it is necessary to move the fence, there must be a guardian present, and keep the following safety distances: Source: www.lw3721.com
