Description
The utility model is the bus duct that is used for feed and distribution about a kind of, more particularly about a kind of high temperature resistant, refractory heat-insulating type bus duct.
Bus duct is a kind of equipment that is used for feed and distribution.Its compact conformation is attractive in appearance, and is safe and reliable to operation, under the situation that backbone does not have a power failure, can draw power supply easily along separate routes by coupling box, thereby replace traditional cable distribution system.At present, bus duct has been widely used in industrial and mining enterprises, skyscraper, exhibition facility etc. at home and abroad upward as novel distribution facility.
Though bus duct is compared with cable under normal the use remarkable advantages is arranged, it does not have fire-resistant function.In case breaking out of fire not only can not be carried out the ordinary production power supply, even also can't or organize fire fighting that necessary communication power supply is provided for fire alarm.Along with rapid economic development, fire incident also increases day by day, and common bus duct can't be applicable to the many occasions that fire resistance had requirement.
For this reason, people have carried out a large amount of research to fire resistant busbar for many years, and have declared multinomial patent, and are specific as follows: 1. application number/notification number: CN-94239377/2248410 " fire prevention bus duct "; 2. application number/notification number: CN-94239616/2206504 " heat-insulating, fire-preventing bus duct "; 3. application number/notification number: CN-95225302/2257100 " fire safe type closed type air isolated bus groove "; 4. application number/notification number: CN-95244095/2242285 " fire resistant busbar "; 5. application number/notification number: CN-96210599/2288537 " fire-resistant concentration bus duct "; 6. application number/notification number: CN-96222060/2272608 " fire resistant busbar "; 7. application number/notification number: CN-96232179/2282740 " fire resistant busbar "; 8. application number/notification number: CN-96232191/2282741 " flame retardant type bus duct "; 9. application number/notification number: CN-96244172/2286935 " fire resistant busbar ".
Say that strictly from the content of above-mentioned patent reflection, they are not complete fire-resistant bus ducts truly.Though this is because they have also designed some respectively such as mica powder, refractory slab, thermal contraction casing tube, thermal expansion type thermal insulation board in bus duct conducting copper outside, and skin is coated with fireproof paint etc., but limit because of the performance of these materials own, they all do not reach the requirement of long-time anti-big fire.For example, in the above-mentioned patent, the highest high temperature resistant notification number is No. 94239616 patents, also only can be anti-840 ℃ of high temperature of fire initial stage 30 minutes.In fact, in fire incident, the flame temperature when many combustible materials burn is all greater than 840 ℃.In addition, 30 minutes fire resistance period also differs and guarantees time needs from fire generation, discovery, warning, fire engine are reached the spot surely, especially to the large industrial enterprise of remote location and the relatively more crowded big city of peak on and off duty road, what 30 minutes fire resistance period was not enough especially.This shows that above-mentioned all patents all can not be called complete fire-resistant bus duct truly because of the defective on the design the selection of material, can not satisfy the requirement of bus duct fire resistance.
The purpose of this utility model provides a kind of high temperature resistant, fire-resistant, protection against the tide and high-temperature insulation, light weight, easily is shaped and firm, indeformable, long-lived bus duct.
