Outdoor rain-proof and lightning-proof transformer

Abstract

The invention relates to the technical field of transformers, and discloses an outdoor rainproof and lightning-proof transformer which comprises a transformer body. Heat dissipation frames with hollow centers are fixedly connected to the front, rear, left and right surfaces of the transformer body, and a plurality of heat dissipation fins are fixedly connected to the upper and lower inner walls of the heat dissipation frames at equal intervals. The top surface of each heat dissipation frame is provided with a cylindrical bulge, the outer wall of the cylindrical bulge is sleeved with a water tank, and the top surface of the transformer body is provided with holes corresponding to the positions of every two heat dissipation fins, and the inner wall of each hole is sleeved with a shifting rod. Through the arrangement of a baffle plate, the transformer body can be directly cooled through rainwater in rainy days, so that the baffle can automatically seal the gaps between the heat dissipation fins, the problem that rainwater mixed with dust and other impurities fall onto the heat dissipation fins and adhere to the heat dissipation fins, and consequently heat dissipation is poor is solved; the baffles can automatically retract to unfold the heat dissipation fins along with evaporation of water in the water tank in sunny days, so that the heat dissipation effect of the heat dissipation fins on the transformer body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an outdoor rainproof and lightning-proof transformer. Background technique [0002] When the outdoor transformer is in use, in order to dissipate heat, a large number of heat sinks will be installed on its outer wall. However, in rainy days, impurities carried or splashed by rainwater will come into contact with the heat sinks, because the heat sinks are arranged in an arrangement. Yes, the impurities on the surface can be removed under the washing of rainwater, but the impurities adhering to the depth of the outer wall of the heat sink are difficult to remove, and then accumulate and adhere after drying, resulting in a decline in heat dissipation. Therefore urgently need a kind of outdoor rain-proof and lightning-proof type transformer to solve the above problems. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the...
