AI Technical Summary
When outdoor transformers operate in environments exposed to direct sunlight, rain, and high temperatures, traditional protective measures suffer from poor heat dissipation or incomplete protection, affecting the normal operation and service life of the transformers.
A combined structure including a protective cover and a heat dissipation cover was designed. The protective cover is inverted funnel-shaped, with a conductive rod cover and a slot at the top. The edge of the slot has a waterproof rubber ring, and there are insert rods and grooves inside. The heat dissipation cover is a box-type structure with a hinge and a box door on the left side, a fan and heat dissipation holes at the top, and a protective net at the bottom. It is combined with a solar panel and an insect-attracting lamp to achieve comprehensive protection and heat dissipation.
It effectively blocks direct sunlight and rain erosion, maintains stable internal temperature of the transformer, enhances mechanical strength, prevents damage, and achieves effective heat dissipation through fans and heat dissipation holes, thus extending the transformer's lifespan.
