The current status of electrical motor maintenance at the second-tier enterprises of the chemical engineering department of the integrated electrical maintenance programme: the electrical motors of the company stone i and ii were repaired on their own and were commissioned to external repair units only after the larger electric burn was destroyed; and the electrical motors of the company pvc, cement and co-source were commissioned to be repaired by external units. In accordance with the general requirements of the ministry of chemical engineering, a unified electrical motor maintenance unit is required, and the operational programme is described as follows: i, basic requirements 1, centralized in a maintenance workshop, with a single beam of more than two tons in the plant to facilitate suspension, equipped with a three-phase power supply, a cable of not less than 50 m2, equipped with a control cabinet, can be debugged. 2. The maintenance staff consists of the existing electrical motor maintenance staff (electro-stell, inc.) of 4-5 personnel. More than three years have passed since the construction of the electrical power maintenance of the stone i and ii company, which has a largely skilled workforce capable of doing this or sharing it. 3 the sharing of the maintenance tools, which combine the maintenance tools of electric stone i and electric stone ii, can save the cost of furniture. The maintenance workshop was only for electrical motors below 110 kw, as the maintenance of large power plants could not be of high quality due to workers and equipment, and the use of more than 110 kw was less well protected, and it was recommended that the repair be done by the external maintenance unit of the ministry of chemical engineering. High voltage generators are generally not self-maintenanced, and the key to high-pressure circuits is to address insulation, which is demanding environmental and technical requirements for maintenance. Most of the maintenance of the high voltage power is to be carried out in conjunction with the machine floor, so the maintenance of the high voltage power is not considered for initial installation. 5. Harmonized treatment of scrap copper. 6. Establishment of maintenance desk accounts by the motor maintenance unit, the cost of which is borne by the maintenance unit. Establishment of an electrically motivated loan account. The table reads as follows: the repairer of the account number number of the motor maintenance desk is required to return to the unit at which the time of the repair is to be delivered. Given the variety of electrical materials, in particular the dozens of varnished wires, which, if purchased for each model, could result in the non-use and waste of some of the materials, it is recommended that a quarterly or annual tender be used, whereby the material company closes and sets the mark, the goods delivered by the winning unit enters the supermarket, the repair unit leads to the supermarket, and the type of model is used, and the used material is automatically supplemented by the winning unit. Material companies follow up on market prices and have the right to make price adjustments based on market prices. 2. Waste copper treatment. The external maintenance units purchase copper lines in exchange for old and new, with a difference between the market price usually around $13 and lower costs. If scrap copper is sold, the price of scrap copper is significantly different from the price of new copper by at least $25, so that the scrap copper has to be recovered by the supplier and the price of scrap copper or the difference is to be determined at the time of the tender. 3. The issue of exit passes. The designated point of repair should be located in the plant area, which would cause problems with the exit permit for the power plant after repairing it
