Description

Closed insulating bus duct

Technical Field

Background

With the emergence of modern engineering facilities and equipment, the power consumption of various industries is increased rapidly, especially in the appearance of numerous high-rise buildings and large-scale factory workshops, the traditional cable serving as a power transmission lead cannot meet the requirement in a large-current transmission system, the parallel connection of multiple cables brings inconvenience to on-site installation, construction and connection, and the bus duct serves as a novel power distribution lead and is produced at present. Bus ducts are a new circuit design developed by the united states that uses copper or aluminum as a conductor, supported by non-olefinic insulation, and then installed in metal slots to form new conductors. For distributing a large amount of power to the various components of the decentralized system. Wire and cable have been increasingly replaced in indoor low voltage power transmission mains engineering projects. The real practical application in japan was in 1954, since then bus ducts were developed. Nowadays, the wiring system is indispensable for electrical equipment and power systems in high-rise buildings, factories, and the like. Because of the need of various building electric power of buildings, factories, etc., and the need has a tendency to increase year by year, the use of the original circuit wiring method, i.e., the pipe-through method, brings many difficulties in construction, and when the power distribution system is to be changed, it is almost impossible to make it simpler, however, if the bus duct is adopted, the purpose can be achieved very easily, and in addition, the building can be more beautiful. In terms of economy, the bus duct itself is expensive compared to cables, but the use of a bus duct makes construction costs much cheaper than those of a bus duct including various accessories for wiring and the entire power system, and this is particularly evident in the case of a large current capacity.

Compared with the traditional cable, the bus duct fully embodies the superiority thereof in large current transmission. At present, however, the sealing performance and the insulating performance in the bus duct are not high enough, so that the efficiency is low in the power transportation process, resource waste is caused, and the use requirements of people are difficult to meet. Therefore, a closed type insulated bus duct with more perfect structure and stronger insulativity and sealing performance is needed.
