Description
Technical field
The utility model belongs to power Transmission technical field, is related to a kind of bus duct, more particularly to a kind of fireproof bus duct.
Background technology
With the rapid development in city, skyscraper is more and more, and building power load sharply increases therewith, original
Electric wire is because its capacity is small, branch is inconvenient, is not easy to the reasons such as boundling management, gradually by capacity is big, branch side
Just, the convenient bus duct substitution of boundling management.Bus duct is widely used in the power Transmission main line of fire control equipment and fire-fighting should
The key projects such as anxious equipment main line, such as in the important engineering such as hotel, airport, subway, therefore the safety of bus duct product
Stability is most important.For example, some bus ducts are when encountering local fire behavior, due to big fire external radiation bus duct shell,
Busbar is caused to generate heat, causes to power off, power-off may lead to the power failure of other key equipments, and bigger property loss is caused to be hindered with personnel
It dies.
Utility model content
To solve problem of the prior art, the purpose of this utility model be to provide a kind of simple in structure, fire resisting effect it is good and
Fireproof bus duct at low cost.
To achieve the above object, the utility model uses following technical scheme：A kind of fireproof bus duct includes hard structure
Layer, top plate is equipped with above hard structure layer, bottom plate is arranged below in hard structure layer；Hard structure layer both sides are equipped with curved sides

Edge layer；Damp-proof layer is equipped with outside insulating layer；Multiple Fuse Type plugs are evenly equipped on damp-proof layer；Between damp-proof layer and hard structure layer
Equipped with fire extinguishing oxidant layer；Fire extinguishing oxidant layer includes the cavity structure that a pair of cross section being correspondingly arranged is L-type, and two cavity structures pass through
Clamping structure connects, and extinguishing chemical is filled in cavity structure；Fuse Type plug is connected with fire extinguishing oxidant layer.
Further, flame retardant coating is equipped between damp-proof layer and insulating layer.
Further, Fuse Type plug runs through damp-proof layer, and Fuse Type plug connects with flame retardant coating.
Further, hard structure layer is without departing from top plate and bottom plate.
Further, curved surface side plate coordinates with hard structure lamellar spacing.
Further, refractory material is filled in flame retardant coating.
Further, the outer rim of bottom plate is without departing from the outer rim of top plate.
Compared with prior art, the beneficial effects of the utility model are as follows：Fuse Type plug connection fire extinguishing oxidant layer is provided with,
When there is fire behavior, Fuse Type plug is melted, and extinguishing chemical melts formed channel by Fuse Type plug and enters inside, into
Row fire extinguishing, simple in structure and fire extinguishing are timely and effective；Fire extinguishing oxidant layer is made of the cavity structure of a pair of of L-type, when fire behavior occurs in part
When, local fire extinguishment can be carried out, when replacement can reduce the component needed replacing, save cost；Hard structure layer is provided with, improves slot
The rigidity of body；It is provided with curved surface side plate and curved surface side plate coordinates with hard structure lamellar spacing, enhance the heat dissipation effect of the utility model
Fruit.
