Description
Technical field
The present invention relates to a kind of fire prevention jack boxes.
Background technique
Bus duct system in power industry power transmission and distribution product generally passes through jack box tapping current and is delivered to electrical equipment,
The crowd is dense that risk is high when place encounters fire for skyscraper, large-scale public place, workshop etc., and loss is serious, need to set
The fireproof bus duct with fire protecting performance is set, fireproof bus duct does not have mating fire prevention jack box, in current tap position fire line
Can be weak, influence the fire protecting performance of total system；The metal cabinet of common busway product is overall structure, and bilayer is simply provided
Fire proofing material is filled after cabinet, filling is difficult.
Summary of the invention
It can be improved the anti-of electric line entirety fire protecting performance the technical problem to be solved by the invention is to provide a kind of
Fiery jack box.
Fire prevention jack box of the invention, the grafting box body including upper opening, the bottom of box are provided with window, in window
It is equipped with to be provided with cooperate with cabinet with the pin of the mating tapping current of fireproof bus duct, cabinet top and seal
Case lid, it is characterised in that: cabinet includes U-shaped outer shell, inner shell that can be nested against one another, with jacket space,
Filled with fire prevention interlayer in jacket space between outer shell, inner shell；
Fire proof seal adhesive tape is provided on the case lid, cabinet coordinate contact surface；
The case lid include can be nested against one another, with jacket space inverted U-shape outer layer lid, internal layer lid, outer cover
Filled with fire prevention interlayer in jacket space between body, internal layer lid；
Position-limited edge that the box opening adjacent margins are constituted with inwardly dislocation bending, can limiting with case lid offer, make
It obtains box side and constitutes zigzag configuration on section；
The fire prevention interlayer is made of mineral wool rope coiling, and having between outer shell, inner shell top edge can assist compressing
The open slot of coiling filling mineral wool rope；
The inner shell is that the overall structure that type bending is constituted once is made by sheet metal, and fire prevention interlayer is composite rock wool
Plate, outer shell are formed by welding by four blocks of side plates, one piece of bottom plate by piece.
Fire prevention jack box of the invention, it is slotting for being filled with fire prevention interlayer in jacket space between layer shell, inner shell
It connects case and protective refractory structure is provided, transmission line entirety fire protecting performance can be enhanced, improve system operating safety factor；Inner layer case
It is coiled outside body by mineral wool rope or composite rock wool slab is constituted after preventing fires interlayer, then piece is passed through by four blocks of side plates, one piece of bottom plate and is welded
The whole outer shell structure for constituting close cover outside fire prevention interlayer is connect, fire prevention interlayer padding is convenient, and by opening
Mouth slot auxiliary compresses fire prevention interlayer, and flameproof effect is good, improves the fire protecting performance of total system.
Detailed description of the invention
Fig. 1 is fire prevention jack box planar structure schematic diagram of the embodiment of the present invention.
Specific embodiment
As shown, a kind of fire prevention jack box includes the grafting box body of upper opening, the bottom of box is provided with window, window
Being equipped in mouthful can be provided with and can match with cabinet with the pin 8 of the mating tapping current of fireproof bus duct, cabinet top
Close sealing case lid, cabinet include can be nested against one another, with jacket space U-shaped outer shell 6, inner shell 4, outer layer
Filled with fire prevention interlayer 5 in jacket space between shell 6, inner shell 4, interlayer of preventing fires provides protective refractory knot for jack box
Structure can enhance transmission line entirety fire protecting performance, improve system operating safety factor.
It is provided with fire proof seal adhesive tape on case lid, cabinet coordinate contact surface, prevents external flue gas from entering inside jack box.
Case lid include can be nested against one another, with jacket space inverted U-shape outer layer lid 1, internal layer lid 2, outer layer
Filled with fire prevention interlayer 3 in jacket space between lid 1, internal layer lid 2, so that case lid also improves fire protecting performance.
Position-limited edge that box opening adjacent margins are constituted with inwardly dislocation bending, can limiting with case lid offer, make
It obtains box side and constitutes zigzag configuration on section, further increase sealing effect.
Fire prevention interlayer 5 can coil the packing material constituted, outer shell 6,4 top edge of inner shell using by mineral wool rope
Between there is the open slot that compression plate can be assisted around filling mineral wool rope, anti-fire screen is constituted by mineral wool rope coiling outside inner shell
After layer, then by four blocks of side plates, one piece of bottom plate whole outer shell of the close cover outside interlayer of preventing fires is formed by welding by piece
Body structure, fire prevention interlayer padding is convenient, and assists compressing fire prevention interlayer by open slot, and flameproof effect is good, improves whole
The fire protecting performance of system system.
Inner shell 4 can also be constituted into overall structure using type bending is once made by sheet metal, fire prevention interlayer 5 is adopted
With composite rock wool slab, close cover is formed by welding outside fire prevention interlayer by piece by four blocks of side plates, one piece of bottom plate in outer shell 6
The whole outer shell structure in portion, fire prevention interlayer padding is convenient, and assists compressing fire prevention interlayer, fire prevention effect by open slot
Fruit is good.
Fire prevention jack box of the invention, it is slotting for being filled with fire prevention interlayer in jacket space between layer shell, inner shell
It connects case and protective refractory structure is provided, transmission line entirety fire protecting performance can be enhanced, improve system operating safety factor；Inner layer case
It is coiled outside body by mineral wool rope or composite rock wool slab is constituted after preventing fires interlayer, then piece is passed through by four blocks of side plates, one piece of bottom plate and is welded
The whole outer shell structure for constituting close cover outside fire prevention interlayer is connect, fire prevention interlayer padding is convenient, and by opening
Mouth slot auxiliary compresses fire prevention interlayer, and flameproof effect is good, improves the fire protecting performance of total system.
