Abstract

The present invention discloses a fire-resistant bus duct. The fire-resistant bus duct comprises a shell and a wire core assembly arranged in the shell, the shell comprises an upper cover plate, a lower bottom plate, a left side plate and a right side plate, a first cavity is formed in a plate body of the upper cover plate, and a second cavity is formed in a plate body of the lower bottom plate; the first cavity and the second cavity are both filled with refractory materials; the wire core assembly comprises an upper support plate, a lower support plate, main body conducting bars arranged between the upper support plate and the lower support plate, insulating layers arranged between the main body conducting bars, and a high-temperature-resistant layer made of a ceramic fiber material; thehigh-temperature-resistant layer is filled between the upper support plate and the insulating layer and between the lower support plate and the insulating layer; and the fireproof bus duct provided bythe invention is good in heat dissipation performance and fireproof performance and high in use safety coefficient.

Description

technical field [0001] The invention relates to the technical field of power transmission equipment, in particular to a fire-resistant busway. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing, 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 multiple cables brings a lot of inconvenience to the site installation and construction connection. The bus duct is a new type of conductor formed by using copper or aluminum as the conductor, supported by non-olefinic insulation, and then installed in the metal slot. Now it has become an indispensable wiring method in high-rise buildings, factories and other electrical equipment and power systems. , More and more instead of wires and cables. ...
