The difference between plateau motor and ordinary motor
Elevation of elevation, the breakdown voltage of the electrical clearance is decreased, so the need to increase the electrical clearance in accordance with the sea level. High elevation, the initial voltage of the corona decreases, and the anti-stun measures of the motor are strengthened.
Medium altitude increases, the air cooling effect is reduced, heat dissipation ability to drop, increase temperature, every 1000 m, elevated temperature to increase by 3-10%, therefore, to fix the motor temperature rise limit.
An increase in altitude causes a decrease in insulation intensity: the insulation intensity of an electric machine is reduced by 8 to 15 percent per 1000 meters, so the insulation strength of the motor is improved.
A plateau motor is an electric machine that USES a site above 1000 meters above sea level. According to the national industry standard plateau motor, there are many levels: they are not more than 2000 meters, 3,000 meters, 4,000 meters, and 5000 meters respectively. With environmental factors that influence the plateau, plateau motor compared with the ordinary motor, the dielectric strength, clearance, limit temperature and anticorona measures shall be adjusted accordingly
