Description

Technical Field

[0001] The utility model belongs to the technical field of wind power controllers and relates to a wind power controller with a protective structure. Background Art

[0002] The wind turbine control module is one of the core components of the wind turbine generator set, and its function is to control the operation of the wind turbine, including starting, stopping, adjusting power output, etc. However, if the control module does not have insulation and waterproof protection structure, it will cause a series of problems.

[0003] First, the insulation problem of the control module. The working environment of wind turbines is usually harsh, affected by natural environmental factors such as high temperature, high humidity, salt spray, ice and snow. These factors will cause the electrical insulation performance of the control module to deteriorate, thereby causing electrical faults such as electric shock and short circuit, affecting the normal operation of the wind turbine.

[0004] Secondly, the waterproof problem of the control module. Wind turbines will be attacked by rain during operation, especially in marine environments, where salt spray and splashing waves will also pose a threat to the control module. If the control module does not have a waterproof protection structure, rain or salt water will enter the control module, which will cause circuit board corrosion, electrical component damage and other faults, thereby affecting the normal operation of the wind turbine.

[0005] In addition, the protection structure of the control module will also affect its reliability and stability. Since wind turbines are usually located in remote areas, maintenance and repair are difficult, so the control module is required to have high reliability and stability. If the control module does not have an effective protection structure, the probability of failure during use will increase, thus affecting the reliability of the entire wind turbine.

[0006] In summary, the lack of insulation and waterproof protection structure in the wind turbine control module will lead to a series of problems, including electrical failure, circuit board corrosion, damage to electrical components, etc., and will also affect its reliability and stability. Therefore, there is an urgent need for a wind turbine controller with a protective structure to solve the above problems. Utility Model Content
