High-low voltage outgoing line terminal side transverse arrangement type oil-immersed transformer

Abstract

The invention provides a high-low voltage outgoing line terminal side transverse arrangement type oil-immersed transformer. The oil-immersed transformer comprises a rectangular box body, internal working parts, a radiating fin and porcelain sleeve type high-low voltage outgoing line terminals, and is characterized in that: the porcelain sleeve type high-low voltage outgoing line terminals are transversely arranged on different side surfaces of the box body respectively, and the peripheries of the porcelain sleeve type high-low voltage outgoing line terminals are additionally provided with protective cover components consisting of rigid protective covers, rubber gaskets and fixed mounting bolts respectively; and because the rigid protective covers have certain mechanical strength, the rigid protective covers can effectively prevent outside impact or collision objects from touching the porcelain sleeve type high-low voltage outgoing line terminals, and stop the creepage distance betweensleeves from becoming shorter due to dust stratification or snowdrift on porcelain sleeve mounting surfaces, and then a reliable service life of the transformer is ensured. Compared with a conventional common oil-immersed transformer, the oil-immersed transformer provided by the invention obviously has the advantages of more reasonable structure, strong external interference resistance, reliable and safe working and the like, and has very strong practicability.

Description

technical field [0001] The invention relates to a power transformation equipment, in particular to an oil-immersed transformer with high and low voltage outgoing line terminals respectively arranged with covers on the sides and horizontally placed high and low voltage outgoing line terminals. 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 outer side of the box, and porcelain sleeve type high and low voltage outlet terminals arranged on the box cover. , because the high and low voltage outlet terminals of the porcelain bushing type are set on the box cover, it is easy to accumulate dust and snow on it, resulting in a smaller creepage distance between the porcelain bushings of the outlet terminals, which will cause a short circuit in the electrical circuit and affect the normal power supply , causing economic losses to the power system; a...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the traditional oil-immersed transformer in the existing structure, such as unreasonable structure, poor anti-interference ability, and difficulty in ensuring work reliability and safety, and provide a high-efficiency transformer. The low-voltage outlet terminals are respectively arranged on the side of the box body, and a protective cover is additionally installed on its periphery, which is conducive to enhancing the anti-interference ability of the oil-immersed transformer and improving the working life of the high-voltage and low-voltage outlet terminals. type transformer
