Description
Technical field
The utility model relates to a kind of explosion-proof power distribution box, belongs to power line protection apparatus field.
Background technology
In the erection of power cable, during power line is connected with electrical appliance and electrical appliance control system installs and run, block terminal this be main installation and proterctive equipment, and use amount is huge, find in actual use: the joint of electric equipment, in the electric equipment operations such as the joint between cable and cable and relay, easy appearance electric leakage, the phenomenons such as short circuit and the sparking of electric shock part, and in reality, often need to contain a large amount of inflammable gas at some, use in the particular surroundingss such as combustible dust, and when there is the phenomenons such as sparking in block terminal, the fire of occurrence of large-area is very easily caused even to explode, therefore in order to overcome this problem, solution conventional at present uses explosion-resistant enclosure to carry out coated to cable joint, reach the object of cable joint and surrounding enviroment being carried out isolating, thus large-area fire can not be caused when electric leakage or the fault such as on fire occur cable joint in the short time or explosion accident occurs, and explosion-resistant enclosure conventional at present mainly relies on rubber weather strip and hard shell to reach the object of isolation, therefore its isolating seal effect is poor, and do not possess prevention and fire-retardant function to cable joint is on fire, fire or explosion phenomenon still can be caused to occur, and adopt all-sealed structure due to it, the phenomenon such as on fire do not occurred in block terminal is lacked and observes timely and report to the police, therefore still there is larger application risk, effectively can not meet the use needs that isolation is explosion-proof.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides a kind of explosion-proof power distribution box.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of explosion-proof power distribution box, by interstar connection room, power frame, smoke alarm, seal cover, fairlead, heat-shrinkable T bush and rubber sprue are formed, wherein interstar connection room and seal cover are bolted, described interstar connection room inwall and seal cover inner surface separately arrange insulating ceramics coating, the outer another coated one deck flame-proof PVC bed course of described insulating ceramics coating, described interstar connection room and the seal cover face of offseting arrange at least one seal groove, described seal cover and seal groove correspondence position relative set sealing strip, wherein sealing strip height is 0.5-2 times of the seal groove degree of depth, width is identical with seal groove width, described interstar connection room sidewall is at least arranged two connection jaws, an exhaust outlet and an air pressure detect mouth, described wiring indoor distances seal cover at least 1 cm distance place separately arranges one deck implosion guard baffle plate, described implosion guard baffle plate and interstar connection room sidewall are hinged, described power frame is arranged in interstar connection room, and distance interstar connection room bottom surface and lateral distance are not less than 1 centimetre, distance implosion guard baffle plate distance is not less than 10 centimetres, described smoke alarm is arranged on power frame, described connection jaws is connected with fairlead one end by bolt, and at least one deck sealing strip is separately set between fairlead and interstar connection room, at least one deck elastic block piece is separately established in fairlead and connection jaws junction, flame-proof PVC bed course is separately established in described fairlead, described exhaust outlet separately arranges pneumatic stopping valve, described air pressure detects order on mouth and arranges dial barometer, in the described fairlead other end, rubber sprue is installed, outer surface establishes at least three wedge shape anti-slip tanks, described rubber sprue separately establishes cable-through hole, described heat-shrinkable T bush one end is coated on the wedge shape anti-slip tank of fairlead, other end distance fairlead at least 5 centimetres.
The utility model structure is simple, easy for installation, electric equipment is isolated from the outside respond well, also there is good warning on fire, fire-retardant and extinguishing effect while possessing anti-leakage function, thus effectively isolation, warning, anti-riot and fire-retardant effect are played to electric equipment, substantially increase the fail safe of supply line and use on-the-spot fail safe.
