Busway without transfer structure

Abstract

The embodiment of the present invention provides a busway without a transfer structure. The heat dissipation performance is improved through a heat-radiation type connector pressing plate, the heat dissipation efficiency is high, and the operation temperature rise of a busbar system is low. Main components including a busbar side plate, a cover plates, a connector pressing plate and a side plate connection piece are made of aluminum alloy materials and are profiles formed in one pultrusion process, the production and manufacturing process is simple, and the labor intensity of workers is low. Wing edges of the connector pressing plate are provided with multiple heat dissipating reinforcing ribs facing an inner side of a busway phase line conductor, joints between adjacent busbar groove sections are directly connected to a busway cover plate and an upper plate cover plate at the same time through boss inner threaded holes in the heat dissipating reinforcing ribs at two ends of the jointpressing plate, and a central upward protruding part has an open groove to form a C-shaped structure to clamp a joint belleville spring. The insulation protection level is high, parts are light, the corrosion resistance performance is good, a surface processing process is not needed, the busway can be directly cut and used after pultrusion, the number of parts is small, the connection is reliable,and the installation and transportation are convenient.

Description

technical field [0001] The invention relates to a non-transfer structure 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 factors such as rain and fog. The surface treatment process is troublesome; the side panel connectors and joints Connectors ne...

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
