Abstract
The utility model discloses a fire proof bus duct, a plurality of conductive bodies of which are arranged in the outer shell, a heat insulation layer is positioned between the bus duct and the conductive body. An insulating layer is positioned between the conductive bodies. An inorganic fire resistant sealing layer is positioned between the conductive body and the heat insulating layer. The utility model is fire and water proof due to the adoption of inorganic fire resistant sealing layer.
Description
Technical field
The utility model relates to a kind of fireproof bus duct, and a plurality of electric conductors have thermal insulation layer in the enclosure between the two, between a plurality of electric conductors insulating barrier is arranged.
Background technology
Bus duct is the device of transmission of electric energy in power supply-distribution system, and fireproof bus duct requires under fire condition, can continue to keep the integrality of circuit, guarantees that power supply is uninterrupted, when requiring simultaneously bus duct generation overload or short circuit yet, do not cause the bus duct burning and cause electrical fire.
The fireproof bus duct structure of producing at common bus duct outsourcing one deck thermal insulation material, adds one deck steel shell substantially as shown in Figure 1 more at present.Do the bus duct of shell with steel plate, its degree of protection is the highest can only accomplish IP54, and outer steel shell under fire condition in 1000 ℃ of flame burning can deform, at this moment degree of protection IP54 does not reach yet.Bus duct as the fire-fighting current supply circuit, will bear strong water spray under fire condition, if degree of protection is lower than IP65 (water of any direction nozzle ejection should not have adverse effect), water just might enter bus duct, thereby the bus duct insulation is descended, cause short circuit accident when serious.Therefore, the fire resistance of this fireproof bus duct is poor, can not waterproof.
Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model has provided that a kind of fire resistance is good, the fireproof bus duct of waterproof.
The technical solution of the utility model is: a plurality of electric conductors of fireproof bus duct have thermal insulation layer in the enclosure between the two, between a plurality of electric conductors insulating barrier is arranged, and wherein also are provided with inorganic fire-resistant sealant between electric conductor and thermal insulation layer.
Because adopted inorganic fire-resistant sealant, institute is so that the utility model fire resistance is good and waterproof.
Description of drawings
Fig. 1 is the structure chart of the fireproof bus duct of prior art;
Fig. 2 is the structure chart of fireproof bus duct of the present utility model.
Embodiment
With reference to the accompanying drawings, will be described in detail embodiment of the present utility model.
Fig. 2 is the structure chart of fireproof bus duct of the present utility model.This fireproof bus duct, a plurality of electric conductors 4 have thermal insulation layer 3 between the two in shell 2, between a plurality of electric conductors 4 insulating barrier 5 is arranged, and also are provided with inorganic fire-resistant sealant 6 between electric conductor and thermal insulation layer.Wherein thermal insulation layer adopts novel light thermal insulation fire proofing material, and electric conductor adopts T2 electrician's copper bar.Described shell adopts the inorganic fire rated partition material of XLH-WB, and described insulating barrier adopts 1531 fast epoxy powders admittedly to be coated with curing process through heat and forms.Outer wall at shell also is provided with one deck fire resistant coating 1.Outer wall at described shell is provided with angle steel 9, and promptly four of described shell angles are fastening by special-purpose angle steel.
Installation process of the present utility model is: form insulating barrier 5 on electric conductor 4, pack into then in the housing of forming by shell 2 and thermal insulation layer 3, behind the correction position, seal with inorganic castable refractory (sealant 6), covering cover plate 7 and insulating layer 8, sprayed fire proofing coating 1 on shell uses angle steel fastening at last then.
Claims (3)
1, a kind of fireproof bus duct, a plurality of electric conductors (4) have thermal insulation layer (3) between the two in shell (2), insulating barrier (5) is arranged between a plurality of electric conductors (4), it is characterized in that: also be provided with inorganic fire-resistant sealant (6) between electric conductor and thermal insulation layer.
