Description
Technical field
The utility model is related to feed system technical field, is specially a kind of new intensive fireproof bus duct.
Background technology
High temperature resistant can be realized, dielectric strength is high, and degree of protection is high, and electric property is superior, the novel refractory busbar of structure
Groove is deep in the keen competition in market to be welcome and designing institute is approved by numerous clients, and especially in generator, Fire lift is fiery
Continuous firing standby lighting during calamity, smoke controlling blower fan, fire hydrant, fire-fighting mercury and water mercury, refuge story illumination, automatic sprinkler fire-extinguishing system,
Chemical pollution is serious, and fire resisting main line distribution requires higher and waits special occasions to use.In the market existing fireproof bus duct from
Overall structure, insulation mode, degree of protection, fire resistance and electric property etc. are all more outmoded, it is impossible to embody fireproof bus duct
The novelty and intention of structure, also its performance can not be from truly realizing fire resistance；Set in existing low pressure power transmission and distribution
There is high temperature resistant, degree of protection is high in applying, can continue what is normally run in the case where occurring fire or being burnt in naked light
Bus duct product typically uses resin-cast bus duct and high-strength insulation bus duct.Resin-cast bus duct can not be adopted when in use
Connected, can be expanded with heat and contract with cold using sleeve structure because the change of environment or temperature is produced with fastener, and its joint area ratio
It is easier to slip, relatively difficult when installing positioning and field joint cast, the resin material of cast does not reach fire prevention, prevents

Note fireproof bus duct is used when fireproof bus duct, and 3C certifications are cast fireproof bus ducts, but their international communication introduction cast are anti-
Fiery bus duct has fire resistance, fire-resistant.But when state ministry of public security specifies experiment tested, cast bus outsourcing 10-
Fireproof coating is sprayed outside 20 centimeters of resistant to elevated temperatures resistance to guncotton, Wai Zai Baogangs shell, housing.Certain sample is to have passed through fire resistance examination
Test.But because the radiating of such bus duct is difficult after experiment, cross-sectional area of conductor need to increase three times, direct during this kind of producer's marketing
Misleading user's pouring bus groove has fire resistance 180 minutes.Cast bus is tested by GA/T 537-2005.4.3.2 in fact, is supplied
Fire 10 minutes or so, lamp goes out short-circuit, takes out the resin poured into a mould during stove and is all melted by fiery position, only surplus copper bar.Pour into a mould bus
Groove is prevented fires and water resistance is all up to standard, it should claim cast-type fireproof bus duct or cast-type water proof bus bar slot.It cannot be used for fire resisting
Power Transmission main line, be mislead user behavior, it should forbid.
Although another high-strength insulation bus duct can be connected firmly, highest degree of protection can only achieve IP54, no
Waterproof can be reached, is prevented fires, anti-corrosion is explosion-proof to wait performance requirement.
