Description

Technical Field

[0001] The utility model relates to a corrosion-resistant bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to each component of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. It has become popular in developed countries abroad, Hong Kong, and Macau. In Guangzhou, Guangdong, my country, more than 90% of the main lines leading to the distribution rooms of buildings with more than 12 floors use bus ducts; bus ducts are used from 630KVA transformers to distribution cabinets.

[0003] The shell of the busbar is usually made of metal. The shell has a split structure and an integrated structure. The split structure shell includes a cover plate and a trough body. The conductive bar and filling material are installed inside the trough body, and then the cover plate is closed. The cover plate and the trough body are usually fixed with bolts. Although the bolt connection mechanism is stable, in order to ensure the connection strength between the trough body and the cover plate, multiple bolts are usually installed to ensure the connection strength. This undoubtedly increases the assembly time and makes the assembly and fixing process of the cover plate and the trough body more cumbersome. Utility Model Content

When connecting the slot body and the cover plate, the fastener is passed through the first mounting hole and the second mounting hole in sequence, and the box body is fixed by the limit rod. Under normal circumstances, the two limit blocks are retracted in the box body. After the fastening mechanism passes through the mounting hole as a whole, the operating rod is pushed downward to make the middle connecting block, the telescopic rod and the limit block move as a whole until the limit block moves to the position where the second through hole is aligned. At this time, the limit block is no longer blocked. Under the action of the spring, the limit block extends out of the box body.
