1). Condensation occurs easily, reducing the insulation resistance of the generator.
2) Heating of the wire increases, causing insulation cracks due to excessive thermal expansion and elongation. The temperature difference between the copper and iron of the rotor is too large, which may cause permanent deformation of the rotor coil.
3) The insulation becomes fragile and may not be able to withstand the impact of mechanical torque generated by a sudden short circuit.
Hello (Yizhong Power Plant) will answer for you:
If the generator wind temperature is too high, the stator coil temperature, the core temperature of iron and the rotor temperature will increase accordingly, causing insulation to appear. Weakening and weakening of mechanical strength will significantly reduce the life of the generator. In severe cases, this pmay cause insulation damage, breakdowns and accidents;
Condensation will easily occur if the wind temperature is high. too low and water droplets will condense on the generator. The insulation capacity of the generator coil is reduced, threatening the safe operation of the generator.
