Description

A kind of intensive bus duct waterproof covering device

Technical field

The utility model relates to the technical field of bus ducts, and in particular to a dense bus duct waterproof covering device.

Background technique

With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly, especially the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to on-site installation and construction connections. Bus duct emerges as a new type of distribution conductor;

The bus duct is a closed metal device composed of copper and aluminum bus columns, which is used to distribute large power to various components of the decentralized system. In indoor low-voltage power transmission trunk line engineering projects, wires and cables have been increasingly replaced, and bus ducts can be divided into many types according to their uses and insulation methods, including intensive bus ducts;

The existing dense bus duct has poor waterproof and heat dissipation effects. In terms of moisture resistance, busbars are prone to moisture and water seepage during construction, resulting in a decrease in phase-to-phase insulation resistance. The heat dissipation of the busbar mainly depends on the casing. Due to the compact arrangement and installation between the lines, the heat energy of the L2 and L3 phases dissipates slowly, resulting in a high temperature rise in the busbar trough. The densely insulated plug-in bus duct is limited by the shell plate and can only produce horizontal sections no larger than 3m. Due to the small air gap between the busbar phases, when the busbar passes a large current, a strong electric force is generated, causing the magnetic oscillation frequency to form a superposition state, and then mechanical vibration occurs, causing excessive noise;

In summary, it can be seen that dense bus ducts have problems such as poor waterproofing and heat dissipation, as well as high noise caused by mechanical vibration caused by superposition of magnetic oscillation frequencies. For this reason, this application proposes a waterproof cover device for dense bus ducts.
