Flame retardant waterproof busway and its manufacturing process

Abstract

The invention discloses a flame-retardant and waterproof busbar, comprising a busbar casing, a conductor frame and a conductor integrated frame. The conductor integrated frame is arranged in the conductor frame, and the upper and lower end faces of the conductor frame are fixed on the Inside the busbar duct housing, a fire-resistant coating is provided on the outside of the busbar duct housing, and a sealing rubber ring layer is provided between the busbar duct housing and the conductor frame. The flame-retardant and waterproof bus duct of the invention has a large protection range, high stability of the board, is not easily deformed after thermal expansion, high temperature resistance, high protection level, can continue to operate normally in the event of a fire or burns in an open flame, and can be waterproof, Fireproof, anti-corrosion and explosion-proof; Fasteners can be used for connection during installation and use, and there will be no thermal expansion and contraction due to changes in the environment and temperature. Water accumulates ash, and the coating will not volatilize toxic gases when heated, avoiding external physical deformation.

Description

technical field [0001] The invention relates to a bus duct and its processing technology, in particular to a flame-retardant and waterproof bus duct and its manufacturing process. Background technique [0002] Modern high-rise buildings and large workshops require huge amounts of electric energy, and in the face of the huge loads that require hundreds of thousands of amperes of strong current, safe and reliable conduction equipment must be selected. The bus duct system is a power distribution device that efficiently transmits current. It is especially adapted to the need for economical and reasonable wiring of higher and higher buildings and large-scale factories.

Problems solved by technology

[0003] However, in actual use, if the insulation treatment is carried out in an unclean space, there will be some conductive particles in the insulation layer, which does not matter at the initial stage of operation, but it will cause insulation damage over time. Thermal stability and dynamic stability are equally important. Due to the influence of factors such as the resistance of the conductor and the AC current surface effect when multiple conductors are close to each other, the busway will cause heat when the current passes through it. In this way, if there is no good insulation and fire resistance measures, it will be extremely difficult. It is easy to cause fire and failure of the busway, which constitutes a major accident, causing serious property loss and hidden dangers to personnel safety
