Description
Technical field
The utility model belongs to cable protection technical field, and in particular to a kind of fire extinguishing comprehensive intelligent monitoring of cable connector
Device.
Background technique
With the demand of urban development, buried cable replaces overhead transmission line to become inexorable trend.Due to buried cable quantity
The reason of being continuously increased, adding underground environment is relatively poor compared to its ventilation and heat for overhead transmission line, and operation is produced
Raw heat cannot distribute very well, most weak link --- the cable connector of especially entire cable run, because of weak heat-dissipating
It will lead to the increase of operation troubles to a certain extent, and close on ignition of cable simultaneously because the open fire of failure generation can not only ignite
Other combustibles in ignition pathway are also possible to, fire hazard is significantly increased.
The mode for also anything not being taken effectively to cool down for cable duct tunnel at present, and it is directed to cable duct tunnel fire proofing one
As use following two mode: 1, fireproof box, i.e., using the method for applying fireproof coating and fire proofing firbre cloth in stainless steel box, still
Its effect is very limited, can neither put out a fire and also not have warning function, reliability is poor；2, increase by one on the basis of fireproof box
A little extinguishing devices have the function of certain active suppression, but because the special environmental factor of cable duct makes it not have alarm function
Energy.There are also common shortcomings, not set relevant detection device to make device itself by damaged or robber for both the above mode simultaneously
It is found when cannot be anxious when tearing open.
Utility model content
In view of the above deficiencies, the utility model provides a kind of cable connector fire extinguishing comprehensive intelligent monitoring device, effectively solves
