If the wind temperature of the generator is too high, the temperature of the stator coil and iron core will increase accordingly, which will weaken the insulation and lose its mechanical strength, greatly shortening the service life. life of the generator. In severe cases, this will damage the generator insulation. A breakdown will cause accidents.
If the wind temperature is too low, the hydrogen gas will condense and leak, causing water droplets to condense on the generator coil, reducing its insulation capacity and damaging the generator. Therefore, the wind temperature of the generator must be maintained within the range specified by the regulations during normal operation.
