Don't have information on the generator manufacturer? You can check it. Additionally, generally speaking, more attention is paid to the cold temperature of hydrogen, which is generally between 40 and 46°. I have checked the relevant specified parameters of a Harbin Electric 350MW generator for you, as shown in the figure, which gives a hot hydrogen temperature of 75°.
Hello (Yizhong Power Station) will give you the answer:
If the wind temperature of the generator is too high, the temperature of the stator coil, the iron core temperature and rotor temperature will increase accordingly, which will weaken the insulation and weaken the mechanical strength, greatly shortening the life of the generator. In severe cases this can cause insulation damage, breakdowns and accidents;
Condensation. and water condensation can easily occurif the wind temperature is too low. Condensation of the balls on the generator coil reduces the insulation capacity and threatens the safe operation of the generator.
