Problems solved by technology

[0003] The heat of the usual offshore wind power cooling system is usually directly cooled by air, or the heat in the related equipment of the wind turbine is transferred out through forced oil-air cooling system, water-air cooling system, etc. The disadvantage is that there are many devices and low reliability. , The volume and weight of the equipment is large, and the generator cabin is directly attacked by sea salt spray and wind and sand, which deteriorates the working environment of the equipment in the cabin and reduces the reliability of the equipment.
In addition, the generator cooling system, lubricating oil cooling system, and converter transformer cooling system of the existing offshore wind power cooling system are all independent, resulting in a large number of system equipment and redundant configuration of backup equipment, which increases the installation cost of the equipment

Description

technical field [0001] The invention relates to the technical field of hydropower air cooling, in particular to an offshore hydropower air cooling system. Background technique [0002] The main heating equipment of wind turbines are generators, gearboxes, converters, transformers and other equipment. The design of the cooling system is directly related to the reliability and safety of the above equipment. When the generating power of a single wind turbine reaches the MW level or above, the heat generated by the equipment is relatively large. If the heat in the equipment cannot be transferred out in time, the safety of the equipment will be seriously affected. Especially in recent years, the power of a single wind turbine has generally reached Therefore, the quality of the cooling system design of the wind turbine is not only related to the safety and reliability of the operation of the wind turbine, but also related to the construction and installation of the wind turbine. ...
