Problems solved by technology

[0003] Due to the complex working environment of the bus duct, it is unavoidable to be impacted or squeezed by external forces. The existing bus duct has low strength and is prone to deformation or damage when subjected to external forces. The service life is short, and the existing bus duct resistance Higher, not only wastes energy, but also generates more heat in the busway, making the busbar work in a high temperature environment for a long time, affecting the service life of the busbar

Abstract

The invention discloses a low-impedance high-strength illuminating bus slot, and relates to the technical field of electrical equipment. The bus slot comprises an upper cover plate, a lower cover plate, two side plates and a bus. A bus containing cavity is defined by the upper cover plate, the lower cover plate and the two side plates, the bus is arranged in the bus containing cavity, and the upper cover plate, the lower cover plate and the two side plates are each prepared from, by mass, 0.35-0.68% of C, 2.26-2.52% of Cr, 0.95-1.18% of Si, 0.66-0.73% of Zn, 2.34-2.58% of Cu, 0.13-0.18% of W,0.35-0.52% of Mn, 0.93-1.27% of Mg, 1.56-1.88% of rare earth elements and the balance Al and inevitable impurities. The strength of the low-impedance high-strength illuminating bus slot is higher thanthat of an existing bus slot, the bus impedance is low, energy can be saved, heat emitted during bus working is reduced, and the service life of the bus slot is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a low-impedance and high-intensity lighting bus duct. 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 factory buildings. The traditional cables used as power transmission wires can no longer meet the requirements in the current high-current transmission system. The parallel use of multi-channel cables has brought a lot of inconvenience to the on-site installation and construction connections. Bus ducts have increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. [0003] Due to the complex working environment of the bus duct, it is unavoidable to be impacted or squeezed by external forces. The existing bus duct has low strength and is prone to deform...
