Abstract
Description
Technical Field
[0001] The utility model belongs to the field of wind power generation control cabinets, in particular to a self-cleaning power generation control cabinet. Background Art
[0002] Wind power generation converts wind energy into mechanical energy, and then converts mechanical energy into electricity. The wind power control cabinet is equipped with relevant electronic components to assist in wind power generation. However, the dust accumulated in common wind power control cabinets after long-term use needs to be cleaned manually. The heat dissipation effect of this type of power generation control cabinet that cannot achieve self-cleaning function is related to the cleaning cycle. The increase in the cleaning cycle will cause excessive dust accumulation, which will make it difficult for the heat inside the control cabinet to dissipate, and then affect the normal operation of electronic components. In severe cases, it may cause the electronic components to self-ignite due to overheating, causing a series of large losses.
[0003] Secondly, because the power generation control cabinet is not equipped with a self-cleaning structure, the operator needs to disconnect the power supply of the control cabinet when cleaning the dust to ensure that the operator works without electricity, thereby protecting the operator's safety. However, disconnecting the power supply means that the power generation equipment cannot work normally during this period.
[0004] In addition, the power generation control cabinet has no self-cleaning function, which requires special cleaning personnel to perform cleaning operations, which will increase corresponding expenses.
[0005] In summary, there are many problems with wind power generation control cabinets without self-cleaning function, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
