The fact that electric power units are the most important among modern agricultural and industrial equipment, and because many users are not aware of the importance of the correct methods of use and of the need to protect themselves, often because of their inappropriate use, which leads to the burning of the electric power, delays in the production process, especially in the agricultural machinery of rural friends, orchard machinery, makes it difficult to repair the electric power plant。
1 the process is preceded by a review of the basic electrical data, a review of the quality of the electrical apparatus, and an understanding of the mechanics of circuitry, voltage, currents, power, wiring methods, polarities, rotation speeds, the application of a universal meter to detect whether the circuital resistance values are within normal values and the adequacy of the resistance to the ground, i. E., insulation。
2 dismantling machines to record the sequence and location of installation of components, determine the cause of burning according to the failure of the rounding group, record the wiring of the wire box prior to dismantling, place and mark the installation of the casing, some of the positions of the body installation are not misfitted, the cause of the breakdown of the visual ring, the short interlocking road, the short circuit, the causing of short circuits, the initiation of single circuits, the operation of a rounding group, and the destruction of a single or three pairs, which can be judged by the burning of the wire。
3 the detachment group shall record the route of the bypass group, the extraction of the line position, insulation, the number of slots, the number of rims, the type of line, the number of zirconies, the length of each swath, the length of the fixed iron core and the size of the inner diameter。
4 rounded grids:
First, the single root or multiple packs are determined according to the type of line, regardless of the number of lines to be rounded, and the sum of the area to be intercepted must be identical or very close to the original type (reference error plus minus 0. 02 mm). It's the right length, it's short, it's bad, it's bad, it's bad and it's easy to hit the shell. Decorate the insulation paper, round the line, off the line. The lower line must be light, not damage the paint-packed skin insulation, so as not to cause short circuits between which insulation paper is used to prevent short circuits, and the lower line must be consistent. Welding is required for the connection to be recorded at the time it is removed and insulated with an insulation tube. The whole line, tie it down, need to be careful not to touch the loop when the rotor is installed。
5 insulation paints, dryed, tied around the wires, then measured the insulation electrical resistance with a meu rock watch, ensuring that the insulation was not compromised before the insulation paints were poured and dried in the oven。
6 installation of electric machines to check the drying of round-groups, insulation paints that are not sticky, insulation resistance of more than 0. 5 mega-metres, installation in reverse order of disassembly, disposal of parts that need to be replaced for maintenance, e. G. Bearings, refuelling maintenance is required for each repair, installation is essential to ensure that each component is good and installed。
In short, electrical maintenance is to record the original data and try to return them to the plant. By the way, the quality of the paint line in the market is determined by the quality of maintenance, with the use of new copper。
