Bus duct capable of realizing holeless connection and assembling method thereof

Abstract

The invention discloses a bus duct capable of realizing holeless connection and an assembling method thereof. The bus duct comprises a casing, wherein an upper casing body and a symmetrically-placed lower casing body constitute a cavity for accommodating a bus, the upper casing body or the lower casing body consists of a transverse side plate as well as two side plates arranged on the U-shaped structure of one end surface of the transverse side plate, outwards-extending straight Z-shaped bent flanges of end surfaces of all the side plates of the upper casing body and the lower casing body are fixedly connected through clamping strips, the clamping strips adopt dovetail-shaped groove clamping structures, and inner side surfaces of grooves and end surfaces, contacted with the inner side surfaces of the grooves, of the flanges adopt inclined structures. Holeless fixed connection of the cavity in the bus duct is realized by the aid of the clamping strips with the grooves and the upper and lower casing bodies provided with the flanges, the waterproof level is increased, all that is required for convenient mounting is to align the upper and lower casing bodies and embed the clamping strips during mounting, the bus duct is symmetric to mount, good in stability, not prone to shake and firm to connect, problems of difficulty in machining and manufacturing, difficulty in mounting and the high cost in the prior art are effectively solved, and the bus duct has the characteristics of simple structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of bus ducts, and relates to a non-porous connecting bus duct, and also relates to an assembly method of the non-porous connecting bus duct. Background technique [0002] Modern high-rise buildings and large workshops require a huge amount of electric energy, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, it is necessary to choose safe and reliable conduction equipment, and the busbar system is a good choice. The busway system is a power distribution device for efficient current transmission, especially to meet the needs of economical and reasonable wiring of increasingly taller buildings and large-scale factories. [0003] The characteristics of the bus duct are series matching, commercial production, small size, large capacity, short design and construction period, convenient assembly and disassembly, non-combustible, safe and reliable, and long service life...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing bus ducts are fastened by drilling and installing screws and nuts. The holes are placed through the bus duct, which makes the waterproof performance of the bus duct worse. In addition, more holes need to be drilled to realize the fastening and installation of the bus duct. The processing procedure is complicated. The cost is high; the Chinese patent application "A Pin Locking Type Intensive Busway" (patent application number 200920051415.6) introduces a non-hole connection method, and the upper and lower plates are fixedly connected to the left and right side plates through the lock pin Realize no-hole connection, rely on the elastic force of the busbar conductor to lock, this method is difficult to manufacture, inconvenient to install, poor in production efficiency, easy to shake, and not high in stability
