Description

Technical Field

[0002] An outdoor transformer refers to a transformer installed outdoors. It plays a vital role in the power system and is mainly used for step-up, step-down and distribution of power in the distribution network. The protection of outdoor transformers is crucial. Since outdoor transformers are placed outdoors, rain will reduce insulation resistance, accelerate the aging of insulation materials, cause short circuits and leakage, and corrode metal parts, reducing the service life of the transformer and increasing the failure rate of the transformer. The transformer will generate a lot of heat during operation, which needs to be dissipated through the heat dissipation system. Traditional radiators and other components will accumulate dust for a long time, which will reduce the heat dissipation effect and cause the transformer temperature to rise. Long-term high-temperature operation will accelerate the aging of insulation materials, reduce the service life of the transformer, and may even cause failures. Summary of the invention
