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 factors such as rain and fog. The surface treatment process is troublesome; the side panel connectors and joints Connectors need to be connected through an adapter plate, and an insulating bushing needs to be set between the adapter plate and the joint bolts. The butterfly spring of the connector is in direct contact with the outermost insulating partition of the connector, and the connection effect is not good. Large quantity, cumbersome installation, cumbersome manufacturing process, high cost, low heat dissipation efficiency of joints, resulting in high temperature rise of busbar system; temperature rise of connectors is an important indicator for testing the safety performance of busway products, traditional connectors have low heat dissipation efficiency

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, segments of the bus duct are connected through joint devices, joint bolt end portions of the joint devices, 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, a wing-edge outer side of the C-shaped structures is provided with multiple heat radiation reinforcement ribs, an inner side is provided with limit grooves for limiting side plate connection members, right-angle connection portions of long edges and short edges of the side plate connection members are provided with reinforcement ribs projecting outwards, and centers of the reinforcement ribs have thread connection holes. The bus duct is advantaged in that disc-shaped springs are clamped in inner chambers of the C-shaped structures of joint device pressure plates, width dimensions of opening portions of the C-shaped structures of the joint device pressure plates mutually adapt to width dimensions of the joint nuts, materialsof the joint device pressure plates and the side plate connection members are aluminum alloy, the quantity of parts is small, connection is reliable, mounting and transportation are convenient, corrosion resistance performance is good, weight is light, and appearance is attractive.
