The outermost layer of the non-direct-burried cable connector of calamity should coat fire proofing, oil-filled cable joint and the joint for laying intensive midium voltage cable
Closed using fire resisting anti-explosion groove box.13.2.2.1 the in-service joint of cable close quarters should install fire prevention channel box additional or take other to prevent
Fiery quarantine measures.
In the erection process of power cable, because laying distance is longer or needs to carry out the reasons such as circuit connection, so that
It result in and multiple cable connectors often occur in a transmission line of electricity, and in use, the incident failure of transmission line of electricity
Such as：Electric leakage, on fire, short-circuit etc., occurrence probability is maximum at cable connector, and cable often may require that in erection process
Contained by some and used in the particular surroundings such as a large amount of inflammable gases, combustible dust, thus when cable connector occur electric leakage, it is on fire
Etc. failure when, easily cause occurrence of large-area fire in addition explode.
In order to overcome this problem, conventional solution is that cable connector is coated using anti-riot shell at present,
To reach the purpose for being isolated cable connector with surrounding enviroment, so that when electric leakage or the failure such as on fire occur for cable connector
The fire or explosion accident that large area will not be triggered in short time occur, but if processing is not in time, can still cause larger
Fire, triggers security incident therefore still to there is larger application risk, it is impossible to effective to meet the anti-riot use need of isolation
Will.
Utility model content
The purpose of this utility model is to provide a kind of new totally-enclosed cable intermediate joint fire extinguishing anti-explosion safety box, to solve
The cable intermediate joint proposed in certainly above-mentioned background technology hinders for some reason causes on fire rear easily because fire extinguishing triggers larger not in time
