Abstract
The invention discloses a fireproof and dampproof cable branch box which comprises a cuboid box body and a rain shielding box cover. The rain shielding box cover is welded to the box body, both the box body and the rain shielding box cover are made of fireproof face plates, the fireproof face plates are of a three-layer structure, the inner layers and the surface layers of the fireproof face plates are iron sheet layers, the middle layers of the fireproof face plates are aerogel plate layers, polyester coatings with the thickness of 2mm coat the iron sheet layers, the interior of the rain shielding box cover is hollow, and an anhydrous calcium chloride drying bag is arranged in the rain shielding box cover. According to the fireproof and dampproof cable branch box, both the box body and the rail shielding box cover are made of the fireproof face plates, the middle layers of the fireproof face plates are the aerogel plate layers, and thus the fireproof and dampproof cable branch box is lighter and better in fireproof performance.
Description
Technical field
The present invention relates to electrical equipment technical field, be specifically related to a kind of fire-proof and damp-proof cable distribution box.
Background technology
Cable distribution box (Cable Distribution Box) is that a kind of being used for implemented tap, branch, continued and the equipment of change-over circuit cable line, most for outdoor.This equipment is not long service time in China, and insider and electric power system are used department to its understanding and understood still inconsistently, particularly to drawing from the external European and American device etc. of patching, have different views.Below the correlation technique key element of cable distribution box is briefly described and is discussed, for the reference of electric power design and running department.
The type of cable distribution box
Cable distribution box is divided into two large classes by its electric formation: a class is not contain any switchgear, only has pair cable socket to process and the annex being connected in casing, relatively simple for structure, small volume, and function is more single, can be described as common distribution box; Another kind of is in case, not only to have the annex of common distribution box, also contains one or more switchgear, and its structure is comparatively complicated, and volume is larger, and interface unit is many, and manufacturing technology difficulty is large, and cost is high, can be described as senior distribution box.
1, common distribution box
In common distribution box, there is no switchgear, inlet wire and outlet link together on electric, and current potential is identical, are suitable for tap or branch connection.Ordinary practice is returned inlet wire to number and is added that outlet returns number and be called minute numbers.Three branch cable distribution boxes for example, it each goes up three equipotential connection contacts mutually, can enter one as one-in-and-two-out or two and go out.Cable distribution box includes U, V, and W three-phase, three-phase circuit structure is identical, and in-line arrangement is together.
2, senior distribution box
Senior distribution box contains switchgear, both can play tap, branch's effect of common distribution box, can play again control, the conversion of power supply circuits and change operational mode.Switch fracture is roughly divided into cable loop inlet wire side and outgoing line side, and both sides current potential can be different.Therefore switchgear itself has larger volume, and the overall dimension of senior distribution box is larger, is highly generally 1.4～1.8 m, and the degree of depth is about 0.9～1.0 m, and length is determined according to contained switchgear number, how between 1.0 m to 2.4 m.The profile of casing is similar to outdoor box transformer, has the door of several activities on case shell, and some doors are to establish for the operation of switchgear, and some doors are to establish for installation or the Maintenance and Repair of cable connector part.
Existing cable distribution box exists in defect aspect heat dispersion, temperature control, affects working effect and useful life.
Summary of the invention
For above-mentioned prior art, the object of the present invention is to provide a kind of fire-proof and damp-proof cable distribution box, it is poor that it is intended to existing cable distribution box fire protecting performance, the problem that moisture effect is poor.。
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of fire-proof and damp-proof cable distribution box, comprise and be the casing of cuboid and hide rain case lid, hiding rain case lid is welded on casing, described casing and screening rain case lid are made by fireproof panel, described fireproof panel is three-decker, nexine and top layer are iron sheet layer, and intermediate layer is aeroge flaggy, are coated with the polyester enamelled coating that one deck 2mm is thick on described iron sheet layer; Described screening rain case lid inner hollow, is placed with the dry bag of anhydrous calcium chloride in screening rain case lid.
Compared with prior art, the present invention has following beneficial effect:
One, casing of the present invention and screening rain case lid are made by fireproof panel, and the intermediate layer of this fireproof panel is aeroge flaggy, and its weight is lighter, and fire protecting performance is better;
Two, in screening rain case lid, be placed with the dry bag of anhydrous calcium chloride, the effectively moisture in humid air in respiratory box.
Accompanying drawing explanation
Fig. 1 is schematic appearance of the present invention;
Fig. 2 is fireproof panel structure chart provided by the invention;
Reference numeral is: 1 for hide rain case lid, 2 for casing, 3 for ditch channel-section steel, 4 for the dry bag of anhydrous calcium chloride, 5 for aeroge flaggy, 6 be iron sheet layer.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
A kind of fire-proof and damp-proof cable distribution box, comprise and be the casing of cuboid and hide rain case lid, hiding rain case lid is welded on casing, described casing and screening rain case lid are made by fireproof panel, described fireproof panel is three-decker, nexine and top layer are iron sheet layer, and intermediate layer is aeroge flaggy, are coated with the polyester enamelled coating that one deck 2mm is thick on described iron sheet layer; Described screening rain case lid inner hollow, is placed with the dry bag of anhydrous calcium chloride in screening rain case lid.Casing of the present invention and screening rain case lid are made by fireproof panel, and the intermediate layer of this fireproof panel is aeroge flaggy, and its weight is lighter, and fire protecting performance is better; In screening rain case lid, be placed with the dry bag of anhydrous calcium chloride, effectively the moisture in humid air in respiratory box.
