Example Embodiment

[0013] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0014] Such as figure 1 As shown, the improved fire-resistant bus duct of the present invention includes a trough body 1. The trough body 1 is composed of an upper cover plate 2, a lower cover plate 3 and two side plates 4, and both ends of the upper cover plate 2 are bent downward and inward The two ends of the lower cover plate 3 are bent upward to form an upper flange 6. The lower flange 5 and the upper flange 6 can prevent rainwater from entering the tank 1, and the two side panels 4 are bent outward to form a horizontal The plate 7, the horizontal plate 7 of the two side plates 4 and the upper cover plate 2 and the lower cover plate 3 are locked by fasteners 14. The tank 1 is filled with an insulator 8. The insulator 8 is mica or asbestos, which has good insulation effect , The tank body 1 is provided with an insulating seat, which includes an upper insu...

Abstract

The invention discloses an improved fire-proof bus duct which comprises a duct body formed by an upper cover plate, a lower cover plate and two lateral plates. Two ends of the upper cover plate are bent inwards and downwards to form lower flanges, two ends of the lower cover plate are bent inwards and upwards to form upper flanges, and the two lateral plates are bent outwards to form transverse plates. The transverse plates of the two lateral plates, the upper cover plate and the lower cover plate are locked through fastening pieces, an insulator fills the duct body, and an insulation support is arranged in the duct body. The insulation support comprises an upper insulation support, a lower insulation support and a bus fixed between the upper insulation support and the lower insulation support. Radiating structures are arranged on the two lateral plates, and a drainage channel is arranged on the lower cover plate at a position close to the inner sides of the upper flanges. The improved fire-proof bus duct has the advantage that radiating inclined holes are arranged on the two lateral plates and are different from common radiating gaps, the upper cover plate and the lower cover plate are bent to form certain angles so prevent rain water from entering the radiating inclined holes, the insulation support is arranged in the duct body, an insulation effect is good, and fire-proof performance is good.

Description

technical field [0001] The invention relates to a bus duct, in particular to an improved fire-resistant bus duct. Background technique [0002] The busway housing forms a busbar placement position for placing the busbar. During use, a large amount of heat will be generated. The existing busway housing includes upper boards, lower boards and side boards. Most of the heat generated by the busbars is transferred To the side plate, there are usually cooling holes on the busway shell, but ordinary cooling holes are prone to water ingress, making the busbar inside damp. If it encounters a high temperature or explosive environment in the workshop, it is prone to fire. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide an improved refractory bus duct with good heat dissipation effect. [0004] The technical scheme adopted in the present invention is: ...
