Maintenance of electrical equipment, security measures to ensure that what
Maintenance of electrical equipment is the safety measures are as follows:1, strict implementation of the "coal mine safety regulations," the provisions of the electricity sector.2, all mechanical and electrical workers must go through rigorous technical training and safety training, qualified after the certificate, undocumented personnel are prohibited posts.3, mechanical and electrical workers to carry the complete power tools and instruments, voltage levels meet the requirements.
0, in the maintenance of the unit, the unit of the internal control components, need special inspection, is strictly prohibited to open the electronic control box.11, the unit test, in the control panel of the unit, the unit before and after cutting motor direction of head and tail of each station by one person to start and stop the operation, before the test, first of all to carry out safety checks on around the unit, after confirmation, can operate.12, in the maintenance of the power supply system, first put the cooling water system, can be maintained, so as not to cooling water into the power system.13, in the maintenance of power equipment, to check the integrity of the electrical equipment and flameproof performance, so that each equipment to meet the requirements of the standard and explosion-proof. 14, any kind of relay protection device failure, power equipment shall not be put into operation.
6, is strictly prohibited live moving, demolition, relocation and maintenance of electrical equipment and lines.7, all cables are not allowed to have a fire joint, tear, leakage phenomenon, such as cable break, should be used with equal effectiveness hot cold patch, allowed to send electricity.8, all electrical equipment is strictly prohibited fire operation, maintenance of electric equipment, should be properly protected, not smashed on the explosion-proof surface, ensure the explosion-proof surface finish and explosion-proof performance, and paint oil or vaseline to evenly.9, timely maintenance control, switch control must hit the "off" position, set off switch handle, and remove the clutch.
4, before each class must listen carefully to the previous report on the operation of the equipment, to understand the existing state of all equipment. 5, the maintenance of electric power equipment insulation must wear protective equipment, strict stop transmission system, stop transmission to a person responsible for the maintenance of switch control equipment, the switch to power and hang people work, no power "brand, and special care, strict implementation of the mine management regulations to stop electric. Only when the gas density is around 20 meters range is lower than 1%, only open power equipment, and use the same grade pencil test in cut off power supply, after the confirmation, discharge, and then can carry out comprehensive maintenance, maintenance end is correct, it can send electricity.
