Shockproof pouring-type fire-proof bus duct

Abstract

The invention provides a shockproof pouring-type fire-proof bus duct. The shockproof pouring-type fire-proof bus duct comprises a plurality of cable trenches for placing cables, an insulated water-proof body for placing the cable trenches, and a fireproof plate arranged outside the insulated water-proof body, wherein the fireproof plate and the insulated water-proof body fit together closely through an inner shell body, and an outer shell body is fixed at the outside of the inner shell body through screws; filler is added in a gap between the inner shell body and the outer shell body, and a plurality of fireproof liquid boxes for containing fireproof liquid are distributed on the top of the bus duct at equal intervals. According to the shockproof pouring-type fire-proof bus duct, insulating resin is poured outside the cable trenches so as to achieve an insulation function and a waterproof function at the same time; since the fireproof plate is enclosed in a shell body, damage to the fireproof plate can be effectively prevented, so that the normal fireproof performance is ensured; since the top of the shell body is provided with the fireproof liquid boxes, the fireproof liquid can be sprayed to the bus duct when being heated so as to achieve a purpose of fire prevention; in addition, the inner shell body and the outer shell body are provided with soft cushion blocks, so a shockproof effect can be achieved.

Description

Technical field [0001] The invention relates to a bus duct, in particular to a shock-proof pouring type refractory bus duct. Background technique [0002] Low-voltage bus ducts are classified according to their functions. Generally, they are divided into three types. 1. Ordinary bus ducts: Mainly run in some ordinary environments and do not have waterproof or fire-resistant functions; 2. Waterproof bus ducts: The protection level needs to reach IP68 and is mainly used for Some damp environments are energized, such as trenches, indoor, open air, and underwater environments with high humidity; 3. Fire-resistant bus duct: Mainly used for some main lines that require high fire protection, such as generator circuits and fire circuits. At present, most of the low-voltage bus ducts on the market only have a single function, and some have dual functions of waterproof and fire resistance. However, it is realized by nailing fireproof boards around the waterproof busbar. The process is roug...

AI Technical Summary

Problems solved by technology

At present, most of the low-voltage bus ducts on the market only have a single function, and some have dual functions of waterproof and fire resistance, but it is realized by nailing fireproof boards around the waterproof busbar. It is easy to be broken and damaged, and the fire resistance is far below the fire protection requirements. The maximum fire resistance is 30 minutes, while the general fire resistance requirements must reach more than 120 minutes.
