Abstract

The invention discloses an oil-immersed transformer cooling circulation protection device, which comprises a top plate, cooling fins, a transformer box body and a cooling box, wherein the top of the transformer box body is fixedly connected with a top plate, the side walls of the two opposite ends of the transformer box body are fixedly connected with a plurality of sets of cooling fins which arevertically and oppositely distributed, two groups of baffles which are horizontally and oppositely distributed are welded on the side wall of one end, adjacent to the cooling fins, of the transformerbox body, a first oil pump and a second oil pump are fixedly mounted on the two groups of baffles respectively, the first oil pump and the second oil pump each at least comprise a pump body fixedly connected with the baffles, an oil outlet pipe and an oil inlet pipe fixedly connected with the side wall of the pump body, and an L-shaped connecting plate welded to the side wall of the pump body, andthe ends, away from the transformer box body, of the two groups of baffles are fixedly connected with the side wall of the cooling box. The cooling circulation protection device is reasonable in structure, the cooling effect is improved compared with a traditional oil-immersed transformer, and application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of transformer cooling, and in particular relates to an oil-immersed transformer cooling cycle protection device. Background technique [0002] Distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. Transformer oil is a petroleum liquid, which has the possibility of burning and has disadvantages in environmental protection. However, due to the excellent performance and low price of transformer oil The vast majority of power transformers still use transformer oil as insulation and cooling medium. [0003] At present, most of the existing oil-immersed transformers only rely on heat sinks for natural heat dissipation and cooling, and the heat dissipation effect is not good. However, if the temperature of the transformer is too high, it will easily cause safety accidents. Therefore, it is urgent to design a ...
