Abstract

The invention discloses a flame-retarding bus slot. A main body structure is designed to be a compact type structure, thus four busbars of a bus are clamped and placed in a bus slot cavity body. The flame-retarding bus slot stops the formation of 'chimney effect' of the bus slot when fire disaster happens, and optimizes material of an outer shell of the bus; the outer shell material is changed from original steel into full stainless steel; moreover, the outer shell of the bus slot is coated with flame-retarding coating; within 3-5 minutes after fire disaster happens, the coating starts to foam and expand, and form a heat isolating layer, and the heat conductivity coefficient is rapidly increased, and heat transmission is effectively reduced. Every performance index of the flame-retarding coating applied to the flame-retarding bus is in accordance with the national standard; the insulating material coated by a conductive busbar component is a mica tape and a ceramic silicon composite tape. According to the testing result, when temperature reaches 600 DEG C, the mica tape and the ceramic silicon composite tape still have very high insulation performance.

Description

Fireproof bus duct
Technical field
What the present invention relates to is that a kind of energy is high temperature resistant, degree of protection is high, in breaking out of fire or can continue the normal fireproof bus duct run when naked light burns, belongs to the technical field of feed system.
Background technology
The height protection fireproof bus duct of novel structure, superior performance is dark in the welcome of numerous clients and the accreditation of designing institute in market with keen competition, on market, existing fireproof bus duct is more outmoded from overall structure, insulation mode etc., cannot embody novelty and the intention of fireproof bus duct structure, its performance can not from truly realizing fire-resistant function; In prior art, have in low pressure power transmission and distribution facility high temperature resistant, degree of protection is high, at breaking out of fire or the bus duct product that can continue normal service requirement when naked light burns, general employing high-strength insulation bus duct or common pouring bus groove, although high-strength insulation bus duct is connected firmly, but most high-protection level is IP54, can not waterproof, fire prevention, anticorrosion, explosion-proof.And common pouring bus groove in use, securing member cannot be adopted to connect, adopt sleeve structure can expand with heat and contract with cold because of the generation that changes of environment and temperature, easily there is slippage in joint area, and locates more difficult when mounted, not easily fixes.Mould material adopts ordinary resin, does not reach fire prevention, requirement for anticorrosion, is not suitable for the demand of the special occasions such as thermoelectricity, chemical pollution, fire-resistant main line distribution.
Summary of the invention
Technical problem to be solved by this invention is, designs a kind of fireproof bus duct that can work at high temperature, in case of fire, and height protects, high temperature resistant, superior performance, good looking appearance, easy for installation.
The technical scheme solving the employing of its technical problem is: design a kind of fireproof bus duct, include: upper and lower cover plates, left side plate, conductive bus bar assembly, joint cover board connecting component, joint side plates connector, mica tape, ceramic silicon composite band, upper cover plate 1, lower cover 11, pre-install fastening with left plate 6, after flip cover, side cover plate is made to be combined into " U " type structure, by conductive bus bar assembly 8 according to A, B, C, N order width faces down to superpose successively and places in U-shaped cavity, right plate 7 folding surface is upwards pushed down busbar alignment cover plate connecting hole, in side, hex bolts tightens up, erection joint cover board connecting component 2 afterwards, upset bus makes cover plate towards upper, another side joint cover board connecting component 2 is installed, and bus two ends joint side plates connector 12 is installed, hex bolts is used itself and both sides joint cover board connecting component 2 to be fixed, conductive bus bar assembly 8 busbar main body is coated with mica tape 9, ceramic silicon composite band 10, mica tape 9 is close to busbar main body and is positioned at internal layer, it is outer that ceramic silicon composite band 10 is coated on mica tape 9, and concrete wrapped method is: mica tape 9 is around coated 1 layer of busbar main body total length (each reserved 65mm in busbar main body two ends), coated 2 layers of ceramic silicon composite band 10.
Fireproof bus duct of the present invention, bus bulk adopts intensive structure, and the clamping of bus 4 busbars is positioned in bus duct cavity, the formation of bus duct " stack effect " when having stopped breaking out of fire, optimize the material of bus shell, sheathing material changes all steel into by original steel, and at bus duct shell spray refractory coating, in 3 ~ 5 minutes of breaking out of fire, coating starts foaming, expands, form thermal insulation layer, conductive coefficient increases rapidly, effectively reduces the transmission of heat.The fireproof coating property indices that refractory busbar uses all meets national standard; The coated insulating material of conductive bus bar assembly is mica tape and ceramic silicon composite band, and according to result of the test, when temperature reaches 600 DEG C, mica tape and ceramic silicon composite band still have very high insulation property.
Fireproof bus duct of the present invention, high temperature resistant, degree of protection is high, in breaking out of fire or normal operation can be continued when naked light burns, can waterproof, fire prevention, anticorrosion, explosion-proof; Securing member can be adopted to connect when installing and using, can not expand with heat and contract with cold because of the generation that changes of environment and temperature, not easily there is slippage in joint area, locates easy when mounted, easily fix; Insulating material adopts fire-resistant, fire resistant resin, and fire prevention, requirement for anticorrosion is high, is applicable to the demand of the special occasions such as thermoelectricity, chemical pollution, fire-resistant main line distribution; Ponding dust stratification is not easily caused on surface, and toxic gas volatilization can not occur, and avoids external physical distortion.
