The drying process device that is used for the cable water inlet, its structural feature is, include dry gas process device, gas conduit and sealing shroud, the dry gas output interface of dry gas process device connects on the gas conduit, gas conduit connects an end of sealing shroud, and the other end of sealing shroud then is connected on the sheath of cable openings.
The dry gas of exporting in the dry gas process device is sent in the cable inner chamber by gas conduit, with the position of dry cable watered and wetting.Sealing shroud is used to prevent that dry gas is excessive, the more important thing is when filling into dry gas, avoids steam in the outside air or dust etc. are brought into the cable inner chamber, avoids making cable to make moist once more, and it is even more serious perhaps to make moist.Remove moisture in the cable by charging into dry gas, simple in structure, using method is simple, quick and easy, science, and can thoroughly solve the reluctant difficult problem in cable water inlet back: the water inlet cable does not need other replacing, therefore not only save substantial contribution, also shortened the time of putting into operation greatly.
The utility model can further be specially:
The dry gas process device includes dried layer, vacuum pump and the air accumulator that connects by the tool of having a sudden inspiration in regular turn.
After the gas process dried layer drying, under the effect of vacuum pump, gas pressurized is stored in the air accumulator.Because cable length is long, the characteristic that airway is little, when adopting dry gas to carry out drying, this dry gas need enter cable under certain pressure, could be with dry gas acting in the whole piece cable cmpletely, reach the best-of-breed technology effect of dry cable watered and wetting part, thereby need to adopt vacuum pump and air accumulator to carry out pressurized treatments.Air accumulator can provide the gas of 0-4 kilogram pressure.
The dried layer can further be specially:
Include the dedusting layer, purifying layer and the drying layer that connect in regular turn.
When adopting extraneous air, need carry out dedusting and purification to air, and then dry, can prevent from like this dust or other are unfavorable for that the material of cable takes cable inside to, influence the normal use of cable.If adopt the air that had purified, then this dried layer can only need one deck drying layer to get final product.
Be filled with circular regeneration formula active drying agent in the drying layer.
This recyclable regenerative formula active drying agent is a kind of drier that utilizes again capable of circulation of environmental protection, can drop to air humidity below 3.5%.
The utility model can also further be specially:
Also include the first humidity detection instrument, it installs the cable access place of gas conduit and cable segment connector.
Can understand the humidity of air inlet so in real time, when humidity surpasses predetermined numerical value, can super wet warning.Control the humidity of air inlet and judge whether to continue air inlet by control dry gas process device then.
In addition, also include the second humidity detection instrument, it is installed in the gas outlet of cable.
The gas outlet of cable is relative cable air inlet, after dry gas enters cable, flows in the core of watered and wetting, and the steam in the cable is taken away, and flows out from the another port of cable, and this port is the gas outlet of cable.The second humidity detection instrument is the humidity that is used for measuring gas port, thus monitoring dried effect.
The utility model can also be realized by following approach:
Also include a kind of gas converter, this gas converter includes an air inlet and a plurality of gas outlet, and air inlet connects the dry gas process device by a gas conduit, and a plurality of gas outlets then are connected on the cable by gas conduit and sealing shroud correspondence.
This gas converter is a kind of gas differentiation device of an import multiple exit, use this transducer after, just can improve the service efficiency of dry gas process device, handle the watered and wetting problem of many cables simultaneously.
In sum, advantage of the present utility model is, a kind of drying process device that is used for the cable water inlet is provided, and by dry up the method for pathogenic dryness body in cable, removes the moisture in the cable, and adopts the scientific and reliable detection method, and result is detected.Use this drying process device handle cable water inlet fault easily and fast, science, thoroughly solved a difficult problem that is difficult to handle after the cable water inlet, not only can save substantial contribution, avoid changing cable, required human and material resources and the financial resources of deduction and exemption engineering construction, can also shorten the time of putting into operation greatly, significant.
