Abstract
The invention relates to a fireproof bus duct, which comprises a shell cover plate, connecting bolts, a conductive copper bar, a fireproof belting and interlayer insulator, shell side plates, fastening bolts and the like. The fireproof bus duct has a compact structure, high transmission current, simultaneously strong short-circuiting strength, safety, reliability, high resistance to mechanical damages and high fireproof performance.
Description
Technical field
The present invention relates to fireproof bus duct, particularly the fireproof bus duct of multiple layer refractory layer structure.
Background technology
Insulating material that common bus duct extensively adopts and insulation annex great majority contain halogens, as PVC, PTFE, the dense smoke that these materials discharge in the big 1kgPVC of smog after burning burning (just beginning to discharge smoke in 150 ℃～270 ℃ the temperature range of PVC before catching fire), can be full of about 500m3 volume fully, the dwelling house of promptly about 200m2 area.Produce pernicious gas in fire, PVC environment towards periphery discharges HCl, makes devices such as electric equipment, power plate, control and protection screen produce corrosion and is subjected to " fire secondary disaster ", and its loss is about bigger 10～20 times than primary fire damage.Even reinforced concrete also damages because of the corrosion that is subjected to the HCl combustion fumes.Because the silicidation reaction in HCl and the cement forms salt, can be diffused into reinforcing bar, thereby cause corrosion.The expansive force of corrosion product (iron rust) can make cement layer break, even fracture.The common bus duct of refractory ability difference is met the about 3min in fire back and is just lost insulation property.Though scorch region being limited in from flame fringe 2.5m with interior flame retardant type bus duct of research and development at present also can only only be kept energising 5min in the actual fire resistance test.Along with economical, scientific and technological developing rapidly, the fireproofing of important department more and more comes into one's own, when particularly fire takes place, for guaranteeing that emergency system can obtain continual supply of electric power.Therefore, the development fire resistant busbar seems important more.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of fireproof bus duct, comprise housing cover, connecting bolt, conducting copper, flame retardant coating, the housing side plate, cross-over block, fastening bolt is characterized in that flame retardant coating is formed by bilayer or sandwich construction.
Wherein, described fireproof bus duct is characterized in that: double-deck flame retardant coating comprises inorganic material and organic material.
Wherein, described fireproof bus duct is characterized in that: this inorganic material is an aluminum oxynitride.
Description of drawings
Fig. 1: structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes housing cover 1, connecting bolt 2, conducting copper 3, flame retardant coating 4, housing side plate 5, cross-over block 6, fastening bolt 7, wherein flame retardant coating 4 is formed by bilayer or sandwich construction, and double-deck flame retardant coating 4 comprises inorganic material and organic material.Flame retardant coating 4 is designed to the sandwich construction design, flame retardant coating 4 materials to select for use with the structure of flame retardant coating be the key of fireproof bus duct, the present invention selects the main material of aluminum oxynitride as layer insulation for use, and is strong mainly due to its fire resistance, avoids producing pernicious gas or halogen in addition.Simultaneously, be different from the pottery of tradition invention, it has excellent plasticity more.At high temperature 980 ℃～1040 ℃ burned 1.5h of this fireproof bus duct apply 1kV voltage simultaneously, can not produce short circuit phenomenon between bus and the bus.Therefore, fireproof bus duct can effectively guarantee the regular supply of electric power when the bus duct electric power system suffers fire.Simultaneously, adopt coating fire-resistant material on the surface of bolt, carry out poured with epoxy resin again and form.The structural design of fireproof bus duct can satisfy the test method requirement of corresponding fire-resistance property through a large amount of testing and verifications, improvement, and therefore, its structural design of the fireproof bus duct that the present invention introduced is feasible.The used various refractory materials of fireproof bus duct all can be provided together at home, therefore technically, all practical economically.In a single day succeeding in developing of fireproof bus duct run into fire for use bus duct power supply places such as skyscraper, standardization factory building, library, subway, civil air defense constructions and installations, Broadcast and Television Center, power plant effective safety guarantee be provided.Therefore fireproof bus duct newly developed has vast market prospect and remarkable social benefit.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection range of claim of the present invention.
