Problems solved by technology
The air-cooled heat dissipation method cannot dissipate heat in such a large high-temperature environment, and the cooling effect is limited; in such a large high-humidity environment, the condensation generated by semiconductor refrigeration will follow the operation (rotation) of the pitch system , so that other components in the cabinet are short-circuited, the creepage distance becomes smaller, and an explosion occurs in severe cases

The invention provides an anti-condensation refrigerating device and method for a variable pitch system, and relates to the technical field of wind power generation systems. The anti-condensation refrigerating device for the variable pitch system comprises a cabinet body, a refrigeration module and a cooling fin, wherein the cooling fin is arranged on the cabinet body; and the refrigeration moduleis mounted on the cooling fin. According to the anti-condensation refrigerating device for the variable pitch system, the temperature in a variable pitch system cabinet can be reduced, the refrigeration effect is ensured, and meanwhile, condensation in the cabinet is effectively prevented, and safe and stable operation of the system is ensured.
Description
technical field [0001] The invention relates to the technical field of wind power generation systems, in particular to an anti-condensation refrigeration device and method for a pitch control system. Background technique [0002] At present, offshore wind power in the wind power industry has entered a stage of large-scale development in recent years. Its pitch system has been subjected to environmental effects such as high temperature and humidity for a long time, and the conditions are harsh. Once it fails, it will cause major economic losses and serious social impact. [0003] In view of the high temperature environment where the current pitch system is located, higher requirements are put forward for the operation stability of the components in the pitch system cabinet, but the heat generation of the core components still cannot meet the operating conditions in the long-term high temperature environment, which makes the heat dissipation problem of the pitch system increas...
