[0002] A steam turbine generator is a device that uses a steam turbine to drive a generator to generate electricity. A steam turbine generator usually uses high-temperature and high-pressure steam as a power source. The steam drives the steam turbine to rotate, which in turn drives the connected generator to generate electricity. This type of power generation is usually used in large power plants. It can effectively utilize the steam energy generated by fuels such as coal and natural gas, and convert it into electrical energy to supply various electrical equipment. Steam turbine generators are a mature and efficient power generation technology that plays an important role in power production.

[0003] The large amount of noise generated when the steam turbine generator is running may affect the personal safety of the workers. Therefore, a closed soundproof cover is usually used to enclose the steam turbine generator to reduce the noise. However, this practice may affect the convenience of repairing and replacing the steam turbine generator, and also reduce the heat dissipation performance of the soundproof cover. For this reason, we propose a soundproof cover for a steam turbine generator. Utility Model Content
