Thermal Conductivity Of Deutz Gensets

Mar. 21, 2022

Hydrohydrogen cooling is to specify water cooling in the sub-coil, hydrogen cooling in the rotor coil, hydrogen cooling on the surface of the stator core and other components.

Hydrogen is one of the gases with low specific gravity, so the ventilation loss is low, the mechanical efficiency of the fan on the rotor of the generator is high, and the thermal conductivity of hydrogen is large, which can quickly export the heat of the generator, and the cooling efficiency is high. Hydrogen doesn't help with combustion. The oxygen content in the generator is less than 2%, so there is very little risk of fire if the generator windings fail.

Advantages:

1. Small specific gravity, small ventilation loss, can improve the efficiency of the generator.

2. Strong fluidity, can greatly improve the heat transfer capacity and heat dissipation capacity.

3. Pure, not easy to oxidize, does not produce ozone when corona occurs, and can protect the insulation of generator.

4. No combustion, when the generator internal insulation breakdown, will not cause fire, expand the accident.

5. Sealed circulation is adopted to reduce dust and moisture into the generator and reduce the maintenance workload of the generator.

Disadvantage

1. A complex hydrogen production equipment and gas conversion system is required.

2. Due to strong hydrogen permeability and high sealing requirements, a set of sealing oil system is required, which increases the workload of operation and maintenance.

3. Hydrogen is flammable and may catch fire. Exposure to open flame or electric arc will burn, mixed with air to a certain proportion will explode, threatening the safety of the generator.

Why not carbon dioxide?

Because it may contain water and other substances in the shell when combined to produce green scale, will adhere to the insulation and components of the generator, seriously deteriorate the cooling effect of the generator, make parts dirty.
