Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine box-type transformer protection technology, specifically to an anti-icing device for protecting wind turbine box-type transformers. Background Technology
[0002] In wind power projects, box-type transformers are a crucial component connecting wind turbines and substation power distribution equipment. In frigid and high-humidity regions, wind turbine blades accumulate varying degrees of ice in winter. This ice can easily slide off and strike the box-type transformer below. The top of the transformer can hardly withstand the free-fall impact of the ice, affecting the safe and stable operation of the equipment. In severe cases, damage to the transformer can lead to burnout of primary equipment in the high-voltage compartment and transformer windings, requiring the transformer to be returned to the factory for repair. This process is lengthy and can result in significant losses. Currently, there is no effective technical solution to mitigate the impact of ice and prevent damage to the transformer's top cover.
