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, fire resistant busbar.
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.
Fire resistant busbar of the present utility model comprises shell, insulating material, conducting copper, refractory insulating layer, and wherein refractory insulating layer is between shell and conducting copper, and insulating material is between the haptic element of conducting copper; Between refractory insulating layer and the conducting copper internal layer can also be arranged, connect by bolt between the internal layer, on the shell fireproof coating or fire-retarding paint can be arranged.
Fire resistant busbar of the present utility model, wherein refractory insulating layer can be made of ceramic fibre layer of cloth, ceramic fibre carpet veneer, glass fibre layer of cloth; Or refractory insulating layer can be made of the varicosity glass fibre layer of cloth, glass fibre layer of cloth, rock wool carpet veneer, the ceramic fibre carpet veneer that are coated with the vermiculite fireproof coating; Or refractory insulating layer can be made of ceramic beaverboard; Or refractory insulating layer can be made of ceramic fibre indefinite form pours.
Fire resistant busbar of the present utility model compared with prior art has following advantage:
1, high temperature resistantly reach 1000 ℃, and in the above-mentioned listed documents, major part is not enumerated the refractory temperature data, minority enumerated but refractory temperature only between 400～800 ℃.
2, high temperature resistant time period reaches 60 minutes, and the longest fire resistance period only 30 minutes of product in the above-mentioned listed documents.
3, under the situation of fire, back of the body temperature is no more than 200 ℃ in 60 minutes, meets the standard among the IS00834, thereby guarantees that bus duct inner copper line and insulating material performance are normally brought into play the bus duct operate as normal in 60 minutes.
4, protection against the tide and high-temperature insulation.This product insulating refractory layer adopts the splendid high-quality inorganic refractory fiber material product of fire resistance, its water absorption is low, the high-temperature insulation performance is good, resistance to chemical attack (except hydrofluoric acid, hot phosphoric acid, the highly basic), is adapted to the work down of the strong most of mal-conditions of humidity, high temperature, chemical corrosivity.
5, light weight easily is shaped.As flexible inorganic fibers goods, quality is lighter than materials such as employed PLASTIC LAMINATED, mica powder in the above-mentioned documents far away, and easily is shaped, be applicable to the bus duct thermal insulation of different shape, all size and fireprotection layer processing, carry and install and use.
6, firm, indeformable, durable in use.
