Description
Technical field
The present invention relates to a kind of explosion-proof power distribution box, belong to power line protection apparatus field.
Background technology
Erection at power cable, electric lines of force be connected with electrical appliance and electrical appliance control system install and run in, block terminal this be main installation and protection equipment, and make consumption huge, find in actual use: the joint of electrical equipment, in the electric equipment operation such as joint and relay between cable and cable, electric leakage easily occurs, the phenomenons such as short circuit and electric shock part sparking, and in reality, often need to contain a large amount of inflammable gas at some, the special environments such as combustible dust use, and when there is the phenomenons such as sparking in block terminal, the fire very easily causing occurrence of large-area even explodes, therefore to overcome this problem, solution conventional at present is to use explosion-resistant enclosure that cable connector is coated with, reach the purpose that cable connector and surrounding enviroment are carried out isolates, thus large-area fire or explosion accident will not be caused to occur in the short time when there is electric leakage or the fault such as on fire when cable connector, and explosion-resistant enclosure conventional at present mainly relies on rubber weather strip and hard shell to reach the purpose of isolation, therefore its isolating seal effect is poor, and do not possess prevention and fire-retardant function to cable connector is on fire, fire or explosion phenomenon still can be caused to occur, and owing to it adopts all-sealed structure, the phenomenon such as on fire not occurred in block terminal is lacked and observes timely and report to the police, therefore still there is bigger application risk, can not effectively meet the use needs that isolation is explosion-proof.
Summary of the invention
The object of the invention is that and overcomes above-mentioned deficiency, it is provided that a kind of explosion-proof power distribution box.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of explosion-proof power distribution box, by interstar connection room, power frame, smoke alarm, seal lid, fairlead, heat-shrinkable T bush and rubber sprue are constituted, wherein interstar connection room is bolted with sealing lid, described interstar connection room inwall and sealing interior surface separately arrange insulating ceramics coating, one layer of flame-proof PVC bed course of another cladding outside described insulating ceramics coating, described interstar connection room arranges at least one seal groove with sealing the lid face of offseting, described sealing lid 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, at least provided with two connection jaws on described interstar connection room sidewall, one air vent and an air pressure detection mouth, described wiring indoor distances seals lid at least 1 cm distance place and separately arranges one layer of 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 of which sealing strip is separately set between fairlead and interstar connection room, fairlead and connection jaws junction separately set at least one of which elastic block piece, flame-proof PVC bed course is separately set in described fairlead, described air vent separately arranges pneumatic stopping valve, on described air pressure detection mouth, order arranges dial barometer, rubber sprue is installed in the described fairlead other end, outer surface sets at least three wedge shape anti-slip tanks, described rubber sprue separately sets 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.
Present configuration is simple, easy for installation, electrical 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 electrical equipment being played isolation, warning, anti-riot and fire-retardant effect, substantially increasing the safety of supply line and using on-the-spot safety.
