Heat dissipation type bus duct

Abstract

The invention provides a heat dissipation type bus duct. The bus duct comprises at least two bus bodies connected by a connection device. The connection device comprises a connecting seat, two ends of the connecting seat are connected with one end of corresponding bus body respectively, the connecting seat comprises an upright post, an upper connecting plate and a lower connecting plate, the upper and lower ends of the upright post are connected with the upper connecting plate and the lower connecting plate vertically, the bus bodies are connected through the connecting seat comprising the upright post, the upper connecting plate and the lower connecting plate, and ventilation passages are formed between the upper connecting plate and the lateral plates of the bus bodies, as well as the lower connecting plate and the lateral plates of the bus bodies, so as to increase air circulation. Therefore, the heat dissipation effect of a bus is improved and a bus system has a simple structure.

Description

technical field [0001] The invention relates to a bus duct, in particular to a bus duct with good heat dissipation performance, and belongs to the technical field of power transmission equipment. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the site installation and construction connection. As a new type of power distribution wire, the plug-in bus duct has emerged at the historic moment. Compared with the traditional cable, it fully demonstrates its superiority in the transmission of large currents. The contact resistance and temperature rise of the joints at both ends of the slot and the ...

Problems solved by technology

In many places, due to the poor heat dissipation of the bus duct connector, the temperature rise at the joint is too high, resulting in damage to the connector, resulting in the burning of the entire bus duct, and even damage to a large number of electrical equipment, resulting in serious economic losses and potential safety hazards

[0003] Conventional connector busbars are tightly wrapped in a small space by insulating partitions and aluminum profiles, and the heat is transferred to the external space completely through the mutual heat conduction of materials. This method has extremely poor heat dissipation performance. Nowadays, due to high ambient temperature during summer , making the heat dissipation of the connector worse, causing the connector to burn out frequently, which is a headache for many manufacturers

The conventional solution is to increase the connector connecting busbar, which is 30%~40% larger than the main busbar of the busway, which wastes materials and increases costs
