A distribution cabinet busbar arrangement structure

Abstract

The invention discloses a power distribution cabinet bus arrangement structure that comprises a cooling liquid seat; vertical annular bus mechanisms are fixedly mounted in mounting holes; a connectingpin is fixedly mounted at the top end of the vertical annular bus mechanism; the connecting pin is connected with a power distribution switch through a lead; the cooling liquid seat is also communicated with a cooling plate through a pair of drainage pipes; the vertical annular bus mechanism comprises a sealing disc. The vertical annular bus mechanism is fixedly mounted in the mounting hole through a bolt; an annular separation ceramic ring is fixedly mounted in the sealing disc; bus plates are fixedly arranged in the annular separation ceramic ring; the bus plates are arranged on the sealingdisc in a circular array mode. The bus plates are arranged on the sealing disc in a circular array mode, the size specifications of the bus plates are neat, the bus plates are suitable for mass production and machining, the bottoms of the bus plates are connected with the cooling liquid seat, heat on the upper portions of the bus plates can be conveyed downwards in time, and normal work of a power distribution system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bus bar connection structure of a power distribution cabinet, in particular to a bus bar arrangement structure of a power distribution cabinet. Background technique [0002] In the prior art, the busbar arrangement structure of a high-voltage switchgear with the application number "CN201820887596.5" includes A-phase busbar, B-phase busbar, C-phase busbar and insulating base, and the two ends of the insulating base are respectively formed There is an installation end face for matching with the preset side panel of the longitudinal rotary cabinet, and three installation ports extending along its length direction and arranged at equal intervals are opened on the insulating base, wherein the A-phase busbar, B-phase busbar The lower ends of the phase busbars and the phase C busbars are arranged in sequence and connected with three installation ports respectively; the electrical clearance of any one of the busb...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned busbar arrangement structure of the high-voltage switchgear still has obvious defects during use: 1. The busbar arrangement structure of the above-mentioned device is a special-shaped structure, which is not conducive to mass production and processing. At the same time, the traditional parallel busbar arrangement structure leads to The gap between the busbars is small, which is not conducive to sufficient heat dissipation; 2. The above-mentioned device does not have an effective heat dissipation device. When a large current passes through the busbar, the temperature will rise, and the failure to remove the heat in time may cause the busbar to expand and bend due to heat. Adjacent busbars are in contact, resulting in a short circuit, which is likely to cause safety accidents
