Fireproof bus groove

Abstract

The invention discloses a fireproof bus groove which is composed of a shell, conductors, insulating layers, fireproof filler and PE conductors. The shell is formed by fixedly connecting an [-shaped cover plate and side plates, the conductors are arranged inside the shell at intervals after the insulating layers coat the outsides of the conductors, the intervals of the conductors are filled with the fireproof filler which is a mineral material, each insulating layer is made by a gold belt, interlayers are arranged at joints of the shell and fastened by fastening members to prevent overflowing of the fireproof filler after the fireproof bus shell is loose under vibration, and the PE conductors are arranged at the edges, close to the side plates, inside the shell.

Description

technical field [0001] The invention relates to a fire-resistant busway capable of high temperature resistance, high protection level, and continuous normal operation in the event of fire or open flame burning, and belongs to the technical field of power feeding systems. Background technique [0002] The high-protection fireproof busway with novel structure and superior performance is welcomed by customers and recognized by the design institute in the fiercely competitive market. The existing fireproof busway on the market is relatively old in terms of overall structure and insulation methods, and cannot reflect fire protection. The novelty and creativity of the busway structure, its performance cannot realize the fire prevention function in the true sense; in the prior art, the low-voltage power transmission and distribution facilities have high temperature resistance, high protection level, and can The busway products required for continuous normal operation generally use ...

[0002] The high-protection fireproof busway with novel structure and superior performance is welcomed by customers and recognized by the design institute in the fiercely competitive market. The existing fireproof busway on the market is relatively old in terms of overall structure and insulation methods, and cannot reflect fire protection. The novelty and creativity of the busway structure, its performance cannot realize the fire prevention function in the true sense; in the prior art, the low-voltage power transmission and distribution facilities have high temperature resistance, high protection level, and can The busway products required for continuous normal operation generally use high-strength insulating busway or ordinary pouring busway. Although the high-strength insulating busway is firmly connected, the highest protection level is IP54, which cannot be waterproof, fireproof, anti-corrosion, or explosion-proof.

However, ordinary cast bus ducts cannot be connected with fasteners when in use. The use of a packaged structure will cause thermal expansion and contraction due to changes in the environment and temperature, and the joints are prone to slipping, and it is difficult to locate and fix during installation.

The casting material is made of ordinary resin, which cannot meet the requirements of fire protection and anticorrosion, and is not suitable for special occasions such as thermal power, chemical pollution, and fire-resistant trunk power distribution.
