Water-and fire-proof Multifunctional bus groove
Technical field
The present invention relates to a kind of water-and fire-proof Multifunctional bus groove.
Background technology
Low voltage bus bar groove divides according to function, is generally divided into three kinds, 1. common bus duct: main energising operation under some conventional environments, does not have waterproof, fire-resistant function; 2. water proof bus bar slot: degree of protection need reach IP68, is mainly used in the energising of some wet environments, as indoor, outdoor, the environment such as under water of trench, high humidity; 3. fireproof bus duct: be mainly used in the main line that some are high to fire-fighting requirements, as generator loop, fire-fighting loop etc.
Low voltage bus bar groove in the market only has simple function mostly, also have and there is waterproof, fire-resistant dual-use function, but it is by nailing on PLASTIC LAMINATED to realize in the surrounding of waterproof bus, technique is coarse, peripheral PLASTIC LAMINATED easily breaks up damage in work progress, refractory ability does not far reach fire-fighting requirements, the highest fire-resistant 30 minutes, and general fire resistant requirements all will reach more than 120 minutes.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of water-and fire-proof Multifunctional bus groove, it has waterproof and fire-resistant dual-use function, and waterproof, fire-resistant effective.
A kind of water-and fire-proof Multifunctional bus groove of the present invention, comprises side by side, spaced heterogeneous conductor, and described heterogeneous conductor closes in the housing; Described heterogeneous conductor is distributed in builds in the insulative water-proof body formed by epoxy resin; The periphery of described insulative water-proof body is coated with PLASTIC LAMINATED, and described housing is coated on the periphery of PLASTIC LAMINATED.
The outer surface of described housing is coated with one deck fireproof plastic.
The thickness of described fireproof plastic is not less than 1mm.
Described housing comprises inner housing and shell body, is filled with alumina silicate felt between described inner housing and shell body.
Advantage of the present invention:
1. outside heterogeneous conductor, build insulating resin, thus while reaching insulation function, there is water-proof function.
2. PLASTIC LAMINATED is enclosed in the inside of housing, effectively can prevents the damage of PLASTIC LAMINATED, thus ensure that normal fire protecting performance.Described housing comprises inner housing and shell body, is filled with alumina silicate felt, thus enhances fire protecting performance between described inner housing and shell body, and two-layer housing makes in big fire, and bus duct still can have enough mechanical strengths and be unlikely to weak.Spray one deck fireproof plastic at the outer surface of housing, thus further enhancing fire protecting performance.Fire resistance period of the present invention, more than 120 minutes, has good fire resistance.

Embodiment
As shown in the figure: a kind of water-and fire-proof Multifunctional bus groove, to comprise side by side, spaced heterogeneous conductor 1, described heterogeneous conductor 1 is enclosed in the housing of steel; Described heterogeneous conductor 1 is distributed in builds in the insulative water-proof body 2 formed by epoxy resin; The periphery of described insulative water-proof body 2 is coated with PLASTIC LAMINATED 3, and described housing is coated on the periphery of PLASTIC LAMINATED 3.
Described housing comprises inner housing 4 and shell body 5, is filled with alumina silicate felt 6 between described inner housing 4 and shell body 5.The outer surface of described shell body 5 is coated with one deck fireproof plastic 7, and the thickness of described fireproof plastic 7 is not less than 1mm.
