Abstract

The invention relates to a practical oil-immersed transformer, which consists of a rectangular box body, internal working parts, a radiating fin on a side surface, porcelain sleeve type high-low voltage outgoing line terminals on a top cover, and a fixed mounting part at the box bottom. Because the peripheries of the porcelain sleeve type high-low voltage outgoing line terminals and the radiating fin are integrally provided with peripheral protective cover components consisting of rigid protective covers, rubber gaskets and mounting bolts in a sealed mode respectively, the fixed mounting part is arranged to have a closed type framework shape, and the rigid protective covers are made of thin steel plates, the practical oil-immersed transformer can be protected from foreign object collision and put and end to electrical short circuiting caused by sleet and dust coverage in any complex and bad environment, and then a reliable service life of the transformer is ensured. The practical oil-immersed transformer effectively overcomes the defects that a conventional oil-immersed transformer is poor in external interference resistance and the working reliability and safety are difficult to guarantee, and has very strong practicability.

Description

technical field [0001] The invention relates to a power transformation equipment, in particular to a practical oil-immersed transformer with full sealing and full insulation and a protective cover. Background technique [0002] The traditional oil-immersed transformers currently used are composed of a rectangular box, working parts arranged inside the box, heat sinks arranged on the side of the box, arranged on the box cover, and a porcelain bushing type high-voltage outlet terminal and a porcelain bushing. The porcelain bushing type outgoing line terminal composed of tubular low-voltage outgoing line terminal and the fixed installation piece arranged on the bottom of the box are composed. Among them: the ceramic bushing type outlet terminal set on the box cover is in a protruding and exposed state, no matter whether the oil-immersed transformer is in the process of mechanical transportation or hoisting, or in the process of network connection after fixed installation, it is...
