Problems solved by technology

[0002] Modern high-rise buildings and large workshops require huge electric energy, and in the face of the strong current required by this huge load, safe and reliable conduction equipment must be selected. The busway system is a power distribution device that efficiently transmits current. Due to the compact structure of the busbar , will usually generate a higher temperature, which is prone to fire. However, the existing busway has poor fireproof performance.

Abstract

The invention discloses an insulating flame-retardant bus duct, comprising a bus duct body; the bus duct body has a frame body structure formed by an upper cover plate, a bottom plate and side plates;fixed connecting plates are arranged at the upper ends and lower ends of the side plates; the fixed connecting plates, arranged at the upper ends and lower ends of the side plates, are respectively and fixedly connected with the upper cover plate and the bottom plate; heat emission holes are formed in the side plates; a fixed press plate is arranged at the lower end of the upper cover plate, andthe two sides of the fixed press plate are fixedly connected with the side plates at the corresponding ends by means of bolts; a refractory slab is arranged at the upper end of the press plate; the space between the refractory slab and the upper cover plate is filled with a refractory aluminum silicate cotton felt; a cavity is formed between the refractory slab and the fixed press plate; bus positioning slots are respectively formed in the fixed press plate and the bottom plate, and are separately provided with an insulation mounting pipe; a bus-bar is installed in each insulation mounting pipe. The insulating flame-retardant bus duct is simple in structure and good in heat dissipation effect, and has good insulation and flame retardant effects.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution switches, in particular to an insulating flame-retardant bus duct and a preparation method thereof. Background technique [0002] Modern high-rise buildings and large workshops require huge amounts of electric energy, and in the face of the strong current required by this huge load, safe and reliable conduction equipment must be selected. The busway system is a power distribution device that efficiently transmits current. Due to the compact structure of the busbar , usually produces a higher temperature and is prone to fire. However, the existing busway has poor fireproof performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bus duct with simple structure, good heat dissipation effect and strong insulation and flame retardancy in view of the above shortcomings of the prior art. [0004] The technic...
