Introduction What does water and hydrogen cooling mean? Why should we use hydrogen air conditioning instead of using a separate water cooling system for the fixed coil?

What does water and hydrogen cooling mean? Why should we use hydrogen air conditioning rather than

The fixed winding adopts a separate water cooling system. The water-cooled winding conductor has a conductive circuit and a waterway. Each group of wire rods contains several empty copper tubes and several solid copper wires. with cooling water to remove the wire rods. The empty copper tube and the solid copper wire are connected at the end of the thermal wire rod slot. The empty copper tube and its empty copper tube are bundled and welded with special water. An empty copper tube is connected to the insulated water branch pipe. The main inlet (or) collector pipe cooling water enters from the end. Cooling of the wire rod is carried out by the other end of the flow circulation to remove heat. generated by the wire rod

The hydrogen cooling system includes a fan housing and the hydrogen cooler is entierly placed inside the generator. The ventilation system adopts radial flow closed circulation ventilation to generate electricity. The machine is arranged alternately in the axial direction with 13 air zones, 6 air inlet zones and 7 wind zones. Two axial fans (each on the steam and excitation side) are installed and rotated. of the iron core and penetrates the rear. The air flows in the radial direction of the iron core in the air inlet area and enters the air gap in the rotating air duct; trough for cooling the rotating winding; the other part is folded again to cool the iron core in the air duct of the iron core machine base and enters the cooler; the hydrogen cooled by the cooler enters in front of the fan. The recirculation alternately enters the radial flow. ventilation to ensure uniform cooling of the generator core winding and rereduce thermal stresses of structural parts and local heat.

Disadvantages: Hydrogen has strong explosive characteristics when mixed with air in a certain proportion, and a hydrogen generator is necessary. The cold system prevents the leakage of the hydrogen shaft seal and the sealing oil system makes the system complex and tedious to operate.

Hydrogen only circulates in the generator chamber. Generally, there are four cold air chambers and. five hot air chambers (four inlets and five outlets, the incoming air is cold air and the outgoing air is hot air (taking 200MW as an example). There is usually a shroud fan thermal at the end of the generator rotor. It rotates with The rotor during operation. These two fans are used to cool the hydrogen cooler at four corners of the generator. The final cold air (hydrogen) is blown into the chamber.re between the stator and the rotor of the generator, then exits and passes through the rotor. hot and cold air chambers in sequence, reaches the middle hot air chamber, comes out from outside the stator chamber and is then cooled by the four-corner cooler.

Hydrogen is produced by electrolysis of water in an electrolyser in a hydrogen station. If the generator leaks hydrogen or other factors cause low hydrogen pressure, the main hydrogen pipe of the hydrogen station can be replenished. 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.
