Abstract
The invention discloses a waterproof anti-explosion box for a cable middle connector. The waterproof anti-explosion box comprises an upper cavity and a lower cavity connected through bolts, the upper cavity and the lower cavity are covered to form a middle connector bin, fast sand filling ports are formed in the upper portion of the upper cavity, end heads are arranged at the two ends of the upper cavity and at the two ends of the lower cavity, a plurality of waterproof grooves are formed in the inner walls of the end heads, and seal rings are arranged on the waterproof grooves. Cover bodies are arranged on the fast sand filling ports, and sealing flat gaskets are arranged between the cover bodies and the fast sand filing ports. The waterproof grooves and the seal rings are arranged on the upper cavity and the lower cavity, the waterproof effect is good, the fast sand filling ports are formed in the upper portion of the upper cavity, and the upper cavity can be conveniently filled with waterproof anti-explosion sand. The waterproof anti-explosion box for the cable middle connector is simple in structure, and can effectively prevent water from entering the anti-explosion box in the state of 1M water depth and provide the good operation environment for the middle connector. By means of the waterproof anti-explosion box for the cable middle connector, the waterproof performance of the cable middle connector is improved, cable faults caused after the middle connector is soaked in water are avoided, and the stable operation of a power grid is maintained.
Description
Technical field
The present invention relates to a kind of waterproof anti-explosion box for cable intermediate joint.
Background technology
At present, some metropolitan main city zone distribution cables reach 4000KM, and running environment is mainly tunnel, box drain, comb, push pipe four part.All there is larger space with upper pathway, when rainy season set or other ground wire pipeline constructions, easily destroyed by pathway main-body, moisture content can collect in old-fashioned armored cassette, and cable end is soaked by moisture content.And my company in recent years more adopts twisted polyethylene cable, this kind of cable greatest drawback is moisture content once enter cable inside from medial head and very easily cause the accident.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of structure simple, easy to make, can be the waterproof anti-explosion box that transition joint provides good running environment.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of waterproof anti-explosion box for cable intermediate joint, its key technology is: it comprises by bolted upper cavity and lower chamber, described upper cavity and lower chamber cover rear formation transition joint storehouse, described upper cavity top be provided with for fill fire prevention anti-arc light quartz sand fast fill Sha Kou, the termination at the two ends of upper and lower cavity, described termination inwall offers some capillary grooves being suitable for different-diameter cable, and this capillary groove is provided with sealing ring; The described sand mouth that fast fills is provided with lid, is 270 degree of spiral lids at described lid, ensures that sealing is tight.
Preferably, described transition joint chamber is cylinder die cavity.
Preferably, upper and lower cavity correspondence position is provided with flange, and this flange is provided with fixing bolt.
Preferably, described capillary groove is the groove of the curved or rectangle of section configuration.
Preferably, each termination keeps at a certain distance away and is arranged side by side 3 capillary grooves, and often end arranges 3 not isometrical capillary grooves for different model cable.
Preferably, the described sand mouth that fast fills arranges 3.
Preferably, the described sand open height that fast fills is 5 ㎝, and diameter is 5 ㎝, described armored cassette overall length 115 ㎝.
Preferably, described termination is notch cuttype hollow circuit cylinder platform.
The beneficial effect adopting technique scheme to produce is: the present invention is provided with upper and lower cavity, upper and lower cavity is provided with capillary groove and sealing ring, waterproof action is good, upper cavity top is provided with fast fills Sha Kou, can easily fire prevention preventing arc sand be filled, after filling, also there is explosion prevention function.Overall structure of the present invention is fairly simple, under the state of depth of water 1M, also can effectively prevent moisture content from entering armored cassette inside, for transition joint provides good running environment.Adopt the present invention to substantially increase the resistance to water of cable intermediate joint, effectively can contain the cable fault because of the soaked rear generation of medial head, safeguard power grid operation, improve power supply reliability, reduce repairing number of times.The present invention is applicable to distribution 10kV cable, comprises the cable in 240mm2,300 mm2,400 mm2 cross sections, and feasibility is strong, and it is convenient to install, applied widely.
