Description

Bus duct housing

technical field

The utility model relates to the technical field of power distribution engineering, in particular to a bus duct shell.

Background technique

The traditional protective ground wire PE line is placed on one side of the busway. Due to electromagnetic induction, the fault current induced on the protective ground wire is 50% higher than the theoretical calculation. The inductance is also different. When the line is long, the three phases are seriously unbalanced under the fault current. The protective ground wire is made of non-magnetic aluminum alloy shell with good conductivity, and it is surrounded by the conductive bar. Because it is as close as possible to the three-phase bus bar, the reactance can be minimized, and the distance between the protective ground wire and the three-phase bus bar is equal. , the same reactance. In this way, whether it is a short-term or continuous phase-to-ground short-circuit fault, this grounding method is better than setting the PE row alone. Therefore, the International Electrotechnical Committee announced and advocated that the outer shell of the electric busbar (busway) should be used as the grounding conductor.

The heat dissipation performance of the busway shell in the prior art is not good, dust and water are easy to accumulate in the busbar, and the corrosion resistance is not good.
