Abstract
The invention discloses a kind of fire resistant busbar, it is related to bus duct technical field.Between top cover plate and bottom cover plate, side plate is installed, fixed using trip bolt between top cover plate, bottom cover plate and side plate, it is provided with the several guide cards fitting tightly between biside plate, the outside of each guide card is all coated with insulating coating, and the outermost of the described guide card being coated with insulating coating is coated with asbestos cord again, several side plates are evenly arranged with the interior lateral surface of side plate raised, and the outside of described side plate interior sides and asbestos cord is filled with refractory filler.It has good fire resistance and water resistance, and insulating coating is high temperature insulation characteristic mica tape or Ceramic silicon rubber band.Form hard ceramic protection layer under the ablation of thermal-flame, and low cigarette, Halogen, make the intensity of bus duct become higher, indeformable, and mineral refractory filler makes the features such as bus duct has good heat dissipation, current-carrying is big, intensity is high.
Description
Technical field：
The present invention relates to a kind of fire resistant busbar, belong to bus duct technical field.
Background technology：
Developing rapidly with city, skyscraper gets more and more, and building power load is anxious therewith
Increase severely and add, original electric wire is because its capacity is little, branch is inconvenient, be not easy to boundling management
Etc. reason, progressively by capacity big, branch is convenient, the convenient bus duct of boundling management replaces.
On market existing fireproof bus duct from overall structure, insulation mode etc. relatively more outmoded it is impossible to
Embody the novelty of fireproof bus duct structure and intention, its performance can not be from truly realizing preventing
Fiery function；And the common bus duct of existing refractory ability difference meet fire after just lose insulation within about 3 minutes
Performance.Although current research and development scorch region is limited in 2.5 meters from flame fringe within resistance
Combustion type bus duct, but in actual fire resistance test, also can only only maintain energising 5 minutes.With economical,
Scientific and technological develops rapidly, and the fireproofing of important department is increasingly taken seriously, and particularly fire is sent out
When raw, continual supply of electric power can be obtained for guarantee emergency system.Therefore, develop fire safe type female
Wire casing more seems important.
Content of the invention：
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of fire resistant busbar.
The fire resistant busbar of the present invention, it comprise top cover plate 1, bottom cover plate 2, trip bolt 3,
Guide card 4, insulating coating 5, refractory filler 6, side plate 7, side plate projection 7-1 and asbestos cord 8,
Side plate 7, top cover plate 1, bottom cover plate 2 and are installed between top cover plate 1 and bottom cover plate 2
Adopt trip bolt 3 fixing between side plate 7, between biside plate 7, be provided with fit tightly several
Guide card 4, the outside of each guide card 4 is all coated with insulating coating 5, and described is coated with insulation
The outermost of the guide card 4 of clad 5 is coated with asbestos cord 8 again, on the interior lateral surface of side plate 7 all
Even it is provided with several side plates projection 7-1, and the outside filling of described side plate 7 inner side and asbestos cord 8
There is refractory filler 6.
Preferably, on the medial surface of described top cover plate 1 and bottom cover plate 2 and side plate 7 all
It is coated with one layer of marine glue.
Preferably, described refractory filler 6 is mineral material, further, described
Mineral material is magnesium oxide mineral,
Preferably, described insulating coating 5 is high temperature insulation characteristic mica tape or ceramic SiClx
Rubber strip.
Beneficial effects of the present invention：The drawbacks of it can overcome prior art, has good fire resistance
And water resistance, be not afraid of humidity, can full-load run for a long time, have better than other fireproof bus ducts or
The advantage of fire-resisting cable, insulating coating is high temperature insulation characteristic mica tape or Ceramic silicon rubber band.
Form hard ceramic protection layer under the ablation of thermal-flame, and low cigarette, Halogen, make bus duct
Intensity become higher, indeformable, and mineral refractory filler make bus duct have good heat dissipation,
The features such as current-carrying is big, intensity is high, described side plate is provided with several projections, increases its thermal diffusivity,
This bus duct can be used for big public of the flows of the people such as skyscraper, important control centre, subway
The place place higher with other fire protection requirements.
Brief description：
For ease of explanation, the present invention is embodied as and accompanying drawing is described in detail by following.
