What are the characteristics of plateau motors? Why can't the general motors be used for plateau areas
High insulation level, good ventilation and cooling performance, and more adaptability to prevent and prevent the structure of anti-structure. In order to meet the conditions of high altitude, low pressure, lack of oxygen, high temperature, high temperature and bad weather.
Compared with ordinary motor, plateau motor is adjusted for insulation strength, electrical clearance, temperature limit and anti-halo measures. 1, the increase in elevation causes the insulation strength to decrease: the insulation intensity should be reduced by 8 to 15% for every 1000 metres. 2, the breakdown voltage of the electrical clearance is decreased, so the need to increase the electrical clearance in accordance with the elevations. For high voltage motor, the initial voltage of the corona is reduced, and the anti-stun measures should be strengthened. The cooling effect of air dielectric decreases, the heat dissipation capacity decreases, the temperature rise increases, each increase of 1000M, the temperature rise should increase by 3-10%, so the temperature rise limit should be corrected. The high altitude is unfavorable to the dc motor. Pay attention to the choice of carbon brush material.
General motor's normal use of the environment temperature is 5 to 40 degrees, at an altitude of 1000 meters the following, the motor structure design and only meet the needs of the geographical climate conditions, so general motors can not adapt to the plateau region of bad environment.
Plateau motor motivated than other plateau powerful allowance, anti-aging, customize electromagnetic scheme according to different altitudes good heat dissipation, antifreeze die condensation etc. General motors is designed at an altitude of 1000 the following: including motor insulation level is low, the plateau thin air cooling no ordinary motor can't satisfy the, sand big strong ultraviolet radiation with a large temperature difference between day and night motor easy internal condensation, aging fast ordinary can't satisfy the... In general, ordinary electric motors can produce fever, condensation, low power, outdoor motor, etc
