Description
Technical field
The present invention relates to a kind of plugging device, be specifically related to a kind of fiber optic cable quick plugging device.
Background technology
Optical cable and cable are the important transmission equipments in electric system, and they are transported to clean electric energy and communication service information from all directions, are the ties that connects each transformer station, each responsible consumer.The safe operation of optical cable and cable, directly have influence on the stable of communication network and electrical network and to user's reliable power supply.The optical cable of below only take is set forth as example, and cable is applicable equally.
OPGW optical cable and ADSS optical cable be as the electric power special optical cable, and with it, the characteristic of exclusive adaptation electric power transmission line is as high as hitch point, safety coefficient stable, anti-high electromagnetic field etc. and being adopted by power telecom network widely.From the actual conditions of power communication network operation, the fault that communications optical cable occurs is in rising trend.Long-term operating statistic the analysis showed that, except being subject to outside destroy, causes the reason of interruption by optical cable, it is also to cause the main cause of Cable's Fault that the design of engineering and construction quality problem, optical fiber cable fitting are installed the problem such as defective, and particularly transformer station's downlead optical cable more easily goes wrong and causes whole Cable's Fault.
Transformer station's downlead optical cable is as the coupling part of line side and transformer substation communication machine room, and all links such as its design, construction, operation maintenance have its singularity.Exactly because the position that it is special and strict mounting process, make its important hidden danger that becomes OPGW and ADSS safe and stable operation, is also a weak link of whole lightguide cable link.
In transformer station in optical cable practice of construction process, the shutoff of guiding optical cable, in rules (DL/T5344-2006 power optical fiber communication engineering acceptance specification) and State Grid Corporation of China issue the documents in recent years, does not have unified construction method and standard.The not good situation of guiding optical cable plugging effect has continued for a long time, and in system, each unit does not all have good method to solve.Especially at extremely frigid zones, if you would western electrical network, North China Power Telecommunication Network, Northeast China Power Grid, Northwest Grid etc., all can occur over the years because of guiding optical cable shutoff not sternly, cause rainy season precipitation through inflow place, space pipe laying, because the pipe internal drainage is bad, cause winter ponding to freeze, cause the optical cable fibre core impaired, an even whole optical cable is scrapped, and causes the situation of communicating interrupt.
Guiding optical cable shutoff at present adopts following several method substantially:
Method one: use fireproof blocking mud to carry out shutoff to guiding optical cable underground pipe is suitable for reading.Mounting process is simple, and the engineering time is short, but the easy aging distortion of shutoff mud easily causes the underground pipe water inlet, and sealing effectiveness is poor, and outward appearance is not attractive in appearance, needs regular reparation, and the maintenance work frequency is high, and the life-span is short.
Method two: again smear in a large number glass cement, coated metal aluminium film outside fireproof blocking mud.Though it is aging to have delayed shutoff mud, than method one sealing effectiveness, but inherent vice is difficult for finding.
Method three: construction in earlier stage, before the guiding fiber cable laying, is installed heat-shrink tube, wait guiding after optical cable welding finishes, carries out the pyrocondensation processing again.Appearance looks elegant, integral sealing, but the easy season cracking of the heat-shrink tube of outdoor use, the life-span is short, cause the underground pipe water inlet, and construction is more complicated.
Method four: the optical cable construction later stage adopts open heat-shrink tube to be processed.Appearance looks elegant, overall sealing performance is good, and the life-span is long, but open heat-shrink tube complicated construction technique needs to use benzine blow lamp, and dangerous high, very easily cause the damage of guiding optical cable, belong to disposable products, this method accounts for 10%, and difficulty of construction is very large.
Method five: the method is to be applied to guide the shutoff between optical cable and underground pipe by the interim fast splicing sleeve pipe of rushing to repair be subject to outside destroy for the cable accident after through transformation.Fast splicing sleeve pipe (with reference to Fig. 1) one-piece construction is spindle, and two is thin, middle thick, two tip diameter 1.3cm, middle maximum gauge 4.5cm.During use, the fast splicing sleeve pipe is cut into to two halves, the tip suitable for reading of sleeve pipe can be mated with the guiding optical cable, and the end opening internal diameter of sleeve pipe and the diameter of underground pipe are complementary, and after processing, go for guiding the shutoff between optical cable and underground pipe.
The fast splicing sleeve pipe can meet our demand to the shutoff of guiding optical cable substantially, and it has following characteristics:
(1) the PVC material is made, and-65 ℃～135 ℃ all can keep sealing;
(1) structure generally is applicable to the shutoff of guiding optical cable.Tip is less, is applicable to the optical cable sealing; The sleeve pipe lower port diameter is larger, bases fit buried optical cable pipe diameter;
(2) sleeve pipe Seal Design suitable for reading, meet on-the-spot waterproof requirement substantially, but the sleeve pipe end opening owing to blocking in the middle of the fast splicing sleeve pipe, and sealing property is bad.
The fast splicing sleeve pipe has solved the problem of guiding optical cable shutoff substantially, but be not to solve fully, it can process the situation of 1～2 optical cable shutoff, if there are many optical cables to need shutoff simultaneously, this method is with regard to some difficulty, and in recent years along with the continuous increase of electric system capacity, the sharp increase of society's power consumption, voltage class of electric power system also constantly increases, large capacity, and high voltage is the principal feature of current electric system.Be mainly used in voltage levels, strong-electromagnetic field intensity, field environment that filthy situation is serious through the quick cable joint coupling of transformation, but its insulating property are poor, creepage distance is shorter, easily in edge flashing accidents such as guiding optical cable and sleeve pipe join generation suitable for reading pollution flashover, mist sudden strain of a muscle, rain sudden strains of a muscle.
