Problems solved by technology

This problem is particularly prominent during the peak summer season, which seriously affects the current carrying capacity of the busbar and the performance of electrical components, the normal operation of the wall bushing body, the safe operation and reliable power supply of the entire line, and even endangers personal safety.
[0003] Under the existing technical conditions, the wall-piercing bushing does not have a dust-proof device for the nozzle, which causes dust and moisture to easily accumulate at the nozzle, making the environment of the nozzle humid and creating a potential threat

Abstract

The invention discloses a wall bushing with high dustproof capability. The wall bushing comprises an insulating bushing (2), a flange plate (3) and a conductor (1). The flange plate (3) is fixed and clamped at the middle part of the bushing (2). The conductor (1) is installed in the bushing (2). The bushing (2) is provided with multiple umbrella skirts (21). The two ends of the bushing (2) are provided with a dustproof end cap (5) in a sealing way. The conductor (1) penetrates through the dustproof end caps (5). The diameter of the dustproof end caps (5) is greater than that of the umbrella skirts (21). The beneficial effects of the wall bushing with high dustproof capability are that dust and moisture can be prevented from entering the bushing to cause the potential danger by arrangement of the dustproof end caps so that the working environment of the bushing can be improved, the service life of the bushing can be prolonged and the creepage phenomenon can be avoided. Heat-radiating fins are arranged so that heat radiating area can be increased, heat transferring efficiency can be enhanced, the heat radiating performance of the bushing can be enhanced and working environment of the bushing can be improved.

Description

technical field [0001] The invention relates to a wall-piercing sleeve, in particular to a wall-piercing sleeve with strong dustproof capability. Background technique [0002] The wall bushing is an important connection part between the transformer and the distribution line, connecting the lead wire of the low-voltage side of the main transformer and the switch room. When the current flows through the main busbar, a magnetic field will be excited on the wall bushing plate fixed on the wall, and eddy current loss will be generated. The eddy current loss will increase sharply with the increase of the working current of the busbar, which will cause the wall bushing plate to heat up. This problem is particularly prominent during the peak summer season, which seriously affects the current carrying capacity of the busbar and the performance of electrical components, the normal operation of the wall bushing body, the safe operation and reliable power supply of the entire line, and...
