Bus duct

Abstract

The invention relates to a bus duct. A casing composed of side plates and a cover plate is internally provided with a phase wire conductor, the side plates and the cover plate are connected side coverplates formed through one-time pultrusion molding, segments of the bus duct are connected through splicers, joint bolt end portions of the splicers, joint nuts and joint pressure plates among outer-most-layer insulation baffle plates are formed by section bars through one-time pultrusion molding, cross sections of the section bars are generally C-shaped structures, two-side wing edges of the C-shaped structures are provided with multiple heat radiation reinforcement ribs facing towards an inner side of the phase wire conductor of the bus duct, a groove is mounted between the adjacent heat radiation reinforcement ribs, an inner side is provided with a limit groove for limiting side plate connection members, and disc-shaped springs are clamped in inner chambers of the C-shaped structures ofsplicer pressure plates. The bus duct is advantaged in that mutual matching mounting of grooves of heat radiation ribs of cross section U-shaped structures of the side plate connection members and mounting grooves of the joint pressure plates is carried out, the internal air contact area of the side plate connection members, joint plates and joint portions of the bus duct is enhanced through theheat radiation reinforcement ribs, heat radiation efficiency is high, the quantity of parts is small, connection is reliable, mounting and transportation are convenient, and corrosion resistance performance is good.

Description

technical field [0001] The invention relates to a bus duct, which is specifically applied to the technical field of manufacture and installation of bus duct products in the low-voltage power transmission and distribution industry. Background technique [0002] In the low-voltage power transmission and distribution industry, the joints between the sections of the busway products are connected and conducted through the connector. The width of the connector is usually larger than the width of the main product of the busway. The connector must pass through the connector before it can be connected to the busway The side panels of the main product are connected. The traditional side panel connectors are generally made of Q235 steel plates, which are heavy, inconvenient for installation and transportation, and are prone to rust due to rain, fog and other factors, and the surface treatment process is troublesome; some aluminum alloy materials The side panel connector has many curved...

Problems solved by technology

[0002] In the low-voltage power transmission and distribution industry, the joints between the sections of the busway products are connected and conducted through the connector. The width of the connector is usually larger than the width of the main product of the busway. The connector must pass through the connector before it can be connected to the busway The side panels of the main product are connected. The traditional side panel connectors are generally made of Q235 steel plates, which are heavy, inconvenient for installation and transportation, and are prone to rust due to rain, fog and other factors, and the surface treatment process is troublesome; some aluminum alloy materials The side panel connector has many curved surfaces, the manufacturing process is cumbersome, the process is complicated, the installation and transportation are inconvenient, and the material utilization rate is not high; and the side panel connector and the connector need to be connected through an adapter plate. Insulation bushings need to be set between the joint bolts, and the butterfly spring of the joint is in direct contact with the outermost insulating partition of the joint, the connection effect is not good, the number of parts is large, the installation is cumbersome, the manufacturing process is troublesome, and the cost is high; the joint The temperature rise of the connector is an important index to test the safety performance of the busway products, and the heat dissipation efficiency of the traditional connector is not high
