Insulation device for perpendicular connection of low-voltage busbar

Abstract

The invention relates to an insulation device for perpendicular connection of a low-voltage busbar. An insulating baseboard and an insulating cover board are fixedly integrated through a fastener, a horizontal busbar and a vertical busbar are arranged between the insulating baseboard and the insulating cover board, and the length direction of the horizontal busbar is perpendicular to that of the vertical busbar; a horizontal busbar installation groove and a horizontal busbar radiating groove are arranged on the insulating baseboard, the horizontal busbar groove is arranged in the horizontal busbar installation groove, and the horizontal busbar is installed in the horizontal busbar installation groove; and a vertical busbar installation groove and a vertical bubar radiating groove are arranged in the insulating cover board, the vertical busbar radiating groove is arranged in the vertical busbar installation groove, and the vertical busbar is arranged in the vertical busbar installation groove. The installation device reduces the phenomenon of interphase short circuit caused by small safe distance during installation, effectively ensures safety operation of power transmission and distribution devices and has the advantages of being simple in structure, reasonable, convenient to use and the like.

Description

Technical field [0001] The invention belongs to low-voltage power transmission and distribution equipment, and in particular relates to an insulation device for vertical connection of low-voltage bus bars. Background technique [0002] In the low-voltage power transmission and distribution equipment, the main busbar is usually used for protection due to insufficient insulation distance. Due to the poor heat dissipation effect of the thermoplastic sleeve, the aging of the rubber and plastic will affect the insulation after heating, especially at the connection. Heating phenomenon, in view of the existing busbar connection problems, currently in China and abroad, thermoplastic sleeves are usually used for protection, which brings concealment to the normal operation of power transmission and distribution. Summary of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an insulation device for vertical connection of l...

AI Technical Summary

Problems solved by technology

[0002] In the low-voltage power transmission and distribution equipment, the main busbar is usually protected by thermoplastic sleeves due to insufficient insulation distance. Due to the poor heat dissipation effect of thermoplastic sleeves, aging of rubber and plastic is easy to occur after heating, which affects insulation, especially at the joints. In view of the problem of busbar connection, thermoplastic sleeves are usually used for protection at home and abroad, which brings hidden dangers to the normal operation of power transmission and distribution.
