Abstract
The utility model relates to the technical field of auxiliary articles of high-voltage cables, in particular to a fire-proof explosion-proof safety box for a cable joint. The fire-proof explosion-proof safety box for a cable joint comprises an explosion-proof casing and a buffer flame-resistant layer, wherein the explosion-proof casing is buckled by two semi-circle metal casings whose central portions are convex, and the buffer flame-resistant layer is attached in the explosion-proof casing. The joint of a high-voltage cable is coated on the convex portion on the central portion of the explosion-proof casing during engineering construction, and the joint is coated in the buffer flame-resistant layer which is provided, and then, the cable joint can be effectively prevented from aging, and short circuit is prevented by manual collision and abrasion, and when the joint catches a fire, the buffer flame-resistant layer can play the purpose of obstructing and extinguishing fire, thereby preventing explosion accidents.
Description
Technical field
The utility model high-tension cable assistant product technical field refers in particular to the fire-proof and explosion-proof safety box of a kind of cable joint.
Background technology
At present, generally using aerial cable or underground cable to carry out high voltage power transmission aspect the electric power conveying.There are many joints in the junction between the cable, and joint easily takes place aging in long-time use, produces sparking, short circuit phenomenon even blasts so that initiation fire causes heavy losses.The joint of the high voltage power transmission overwhelming majority that has accounted in the electric power fire incident on fire, therefore, there is very big potential safety hazard in the cable joint that does not add processing.
The utility model content
The utility model purpose is easily to take place at present high-voltage cable joint aging, the problem that produces sparking, short circuit phenomenon even blast and exist down to initiation fire, and provide a kind of cable joint fire-proof and explosion-proof safety box.
For achieving the above object the following technical scheme of the utility model:
The fire-proof and explosion-proof safety box of a kind of cable joint, it includes explosion-resistant enclosure, buffering flame-retardant layer, and explosion-resistant enclosure is that the two semicircle metal casings fastening of the protruding drum in middle part forms; The buffering that has been sticked in explosion-resistant enclosure flame-retardant layer.
Two semicircle metal casings of wherein said explosion-resistant enclosure are connected and fixed with screw.
Wherein said buffering flame-retardant layer is an asbestos layer.
The beneficial effects of the utility model are: explosion-resistant enclosure of the present utility model is that the two semicircle metal casings fastening of the protruding drum in middle part forms; The buffering that has been sticked in explosion-resistant enclosure flame-retardant layer; The joint of high-tension cable is contained the convex part branch that is arranged on the explosion-resistant enclosure middle part, and the joint is wrapped in the buffering flame-retardant layer of setting; Can prevent effectively that like this cable joint is aging, prevent artificial collision and wearing and tearing and be short-circuited that the buffering flame-retardant layer can play the purpose that intercepts fire extinguishing when on fire when the joint takes place, and then prevents the generation of explosion accident.

Embodiment
Be further elaborated below in conjunction with 1 pair of the utility model of accompanying drawing:
The fire-proof and explosion-proof safety box of a kind of cable joint, it includes explosion-resistant enclosure 1, buffering flame-retardant layer 2, and explosion-resistant enclosure 1 forms for the two semicircle metal casings fastening of the protruding drum in middle part; The buffering that has been sticked in the explosion-resistant enclosure 1 flame-retardant layer 2.
Two semicircle metal casings of explosion-resistant enclosure 1 are connected and fixed with screw 3, and screw 3 is arranged on the edge of two semicircle metal casings, are used for connecting the fastening two semicircle metal casings that fasten, and handled easily connects closely like this.
As preferred embodiments of the present utility model, the material selection asbestos material of buffering flame-retardant layer 2, asbestos are the good buffering refractory materials of a kind of cost performance.
During use, the joint 41 of high-tension cable 4 is contained the convex part branch that is arranged on explosion-resistant enclosure 1 middle part, the joint is wrapped in 2 li of the buffering flame-retardant layers of setting; Can prevent effectively that like this cable joint 41 is aging, prevent artificial collision and wearing and tearing and be short-circuited that buffering flame-retardant layer 2 can play the purpose that intercepts fire extinguishing when on fire when joint 41 places take place, and then prevents the generation of explosion accident.
The above embodiment, it is preferred embodiments of the present utility model, and unrestrictedly execute scope in fact, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, all should be included in the utility model patent claim.
