Hydrogen only circulates in the generator chamber. There are generally four cold air chambers and five hot air chambers (four inlets and five outlets, cold air in and hot air out, taking 200 MW as an example). The generator rotor There is usually a powder-coated fan at the bottom, which rotates with the rotor during operation. These two fans blow the cold air (hydrogen) cooled by the hydrogen cooler to the four corners of the generator into the chamber between the generator. generator stator and rotor, then it comes out, passes through the hot and cold air chambers in sequence, reaches the middle hot air chamber, comes out from outside the stator chamber, and then is cooled by the four corner cooler to start a new cycle.
Hydrogen is produced by electrolysis of water in an electrolyser in a hydrogen station. If the generator leaks hydrogen or other factors cause a failureible hydrogen pressure, the main hydrogen pipe of the hydrogen station can be refilled. If the purity of the hydrogen does not meet standards, the hydrogen is vented from the generator to the atmosphere.
Hydrogen-cooled generators use hydrogen gas to cool the generator rotor.
First you need to explain what type of generator it is and how powerful it is? As far as I know, there are no specific regulations on the temperature of wind or water used to cool generators. Of course, wind or higher temperature water cannot be used, otherwise they will not be able to cool the generator. Smaller oil, gas and wind generators are naturally air-cooled, and larger ones have their own fan. If this is insufficient, a fan can be added. The hydroelectric generator hasits own water cooling device and fan can also be added. The temperature of all generators generally cannot exceed 80 degrees.
