There are many, including software engineers, hardware design engineers, mechanical design engineers, and field service engineers. It usually depends on the level you can reach. Generally speaking, software engineers and field service engineers have higher salaries, but they are. all relatively hard work. New graduates can also get 4000-5000.
Hydrogen is one of the gases with the lowest specific gravity, so the ventilation loss is small. The fan on the generator rotor in the turbine generator set. has high mechanical efficiency and the thermal conductivity of hydrogen is high. The coefficient is large, the heat of the generator can be quickly dissipated, and the cooling efficiency is high. Hydrogen does not support combustion. The oxygen content of the generator is less than 2%, the risThe fire risk is therefore very low in the event of generator winding failure.
The generator of the turbogenerator group must therefore be cooled by hydrogen.
A generator whose stator and/or rotor are cooled by hydrogen. There are mainly all-hydrogen cooling and stator windings with internal water cooling, the rotor winding and stator core are hydrogen cooled (water hydrogen), and the windings stator and rotor windings with internal water cooling, the stator core is hydrogen cooled (water hydrogen). ).
The windings and iron core of the generator generate heat during operation. In order to avoid burns due to excessive temperature, coolants include air, water, hydrogen, oil, freon, etc. , among which hydrogen is the most widely used because the hydrogen presente the advantages of good thermal conductivity (thermal conductivity is 8.4 times that of air), low density and rapid diffusion. It has a good cooling effect and is easy to carry. and can be recycled.
