First of all, you need to explain what kind of generator it is and how powerful it is? As far as I know, there are no special regulations on the temperature of wind or water used for cooling generators. Of course, higher temperature wind or water cannot be used, otherwise it will not be able to cool the generator. Small oil, gas, and wind generators are naturally air-cooled, and larger ones have their own fan devices. If not enough, a fan can be added. The hydroelectric generator has its own water cooling device, and a fan can also be added. The temperature of all generators generally cannot exceed 80 degrees.
Hello (Yizhong Power Station) will answer for you:
If the generator wind temperature is too high, the stator coil temperature, iron core temperature, and rotor temperature will increase accordingly, causing insulation to occur. Embrittlement and weakened mechanical strength will greatly shorten the life of the generator. In severe cases, it may cause insulation damage, breakdown, and accidents;
Condensation will easily occur if the wind temperature is 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.
