Description
Technical field
Enter the station method under drawing the present invention relates to ultra-high-tension power transmission line field more particularly to a kind of distribution building OPGW optical cable.
Background technique
OPGW optical cable (Optical Fiber Composite Overhead Ground Wire optical fiber composite overhead
Line), refer to and optical fiber is placed in the ground wire of aerial high voltage power line, to constitute the fiber optic communication network on transmission line of electricity,
Dual function with common aerial earth wire and communications optical cable, therefore be widely used in electric system.OPGW optical cable exists
When introducing distribution building, the strain insulator-string ground wire needs of the strain insulator-string of fixed OPGW optical cable connect with the ground wire on distribution building roof, and
OPGW cannot directly enter distribution building, must with the guiding cable connection of communication room, to form fiber-optic communications traffic pipeline.
Currently, existing distribution building OPGW optical cable enters the station, introducing method generally uses OPGW optical cable to climb over parapet upwards
Afterwards, the continuous guiding optical cable of the connector box transfer changing-over being arranged on the inside of parapet, then in the roof pipe laying through walls in distribution building, guiding
Optical cable enters distribution building by pipeline, and across distribution building inner space access communications room or secondary device room.In the method
Because connector box directly it is exposed outside, and then make OPGW optical cable and guide optical cable between connecting Environmental security reliability under.Together
When, in the wall in traditional distribution building, because not considering to introduce OPGW optical cable, and then it is not beforehand on distribution building roof through walls
Pipe laying design, the cable floor for being provided with guiding optical cable in addition are generally located on the bottom in distribution building, this results in OPGW optical cable
Conversion connecting cannot be carried out with the guiding optical cable in communications equipment room；It, can be to distribution building meanwhile if subsequent pipe laying through walls on roof
Integral house structure impact, in turn result in security performance reduction technological deficiency.Therefore it is not made for roof through walls
The distribution building of pipe laying design, how the introducing of entering the station of safe and reliable realizations OPGW optical cable becomes nowadays urgently to be resolved ask
Topic.
Summary of the invention
For this purpose, the technical problem to be solved in the present invention is that overcoming the OPGW optical cable of the prior art when entering the station because of conventional electrical distribution
The connector box in building is exposed outside, while the technological deficiency that pipe laying through walls is designed and can not be introduced is not made on roof, to provide one
Plant the method that enters the station under safe and reliable distribution building OPGW optical cable draws.
To achieve the goals above, the present invention provides a kind of method that enters the station under distribution building OPGW optical cable draws, including walks as follows
It is rapid:

It is continuous；
Guiding optical cable is allotted in connector well, and is laid along cable floor to communication room or secondary device room.
Preferably, the step of the extending direction on the ground close to wall along cable floor does a connector well
In, connector well location is in the lower section of OPGW optical cable.
Preferably, guiding optical cable optical cable will be guided in the step of allotting in connector well by pipeline and entering cable
In layer.
Preferably, by OPGW optical cable along the step that wall draws in connector well, the bending radius of OPGW optical cable
Not less than 350mm.
Preferably, OPGW optical cable is drawn the step in connector well along wall further include:
It is plugged in connector well in the end fixation of OPGW optical cable outer cladding Flame-retardant PVC plastic pipe, Flame-retardant PVC plastic pipe,
And waterproof closure processing is done to the two ends of Flame-retardant PVC plastic pipe.
Preferably, also being wrapped the step of the extending direction on the ground close to wall along cable floor does a connector well
It includes:
One angle bar is installed in connector well, connector box is fixedly mounted on angle bar.
Preferably, also being wrapped the step of the extending direction on the ground close to wall along cable floor does a connector well
It includes:
More than one cable frame is set in connector well, and remaining cable frame can be used to store optical cable extra in connector well.
Preferably, remaining cable frame is fixed on the side wall of connector well by expansion bolt when remaining cable frame is arranged.
The method of entering the station has the advantages that under distribution building OPGW optical cable provided by the invention draws
1. do a connector well by the extending direction on the ground close to wall along cable floor, and by OPGW light
Cable draws in connector well along wall, and then realizes OPGW optical cable and guide connector box transfer changing-over of the optical cable in connector well
Continuous, the interior optical cable layout more optimization that makes to stand is beautiful, safe and reliable；Meanwhile it being buried by using perforating on the wall of connector Jing Chu
Pipe, and then the pipeline being connected to inside and outside distribution building is made to be embedded in the bottom of wall, to will not influence the overall structure performance in house.
In conclusion improving the safety and reliability that distribution building OPGW optical cable enters the station by using the method to enter the station under drawing.
2. being connect due in the step of extending direction on the ground close to wall along cable floor does a connector well
Head well location keeps OPGW optical cable cable run distance short in the lower section of OPGW optical cable, when route breaks down, facilitates maintenance personal
Outside distribution building can the route in butt joint well repair, while but also in OPGW optical cable and distribution building electrical equipment away from
From farther out, to reduce its mutual electromagnetic interference.
3. that will guide optical cable in the step of allotting in connector well, guiding optical cable is entered in cable floor by pipeline, into
And it realizes guiding optical cable and is allotted out of connector well into cable floor, and lay along cable floor to communication room or secondary device room.
4. since OPGW optical cable is drawn the step in connector well along wall further include: in OPGW optical cable outer cladding PVC
The end fixation of flame retardant plastic expects pipe, Flame-retardant PVC plastic pipe is plugged in connector well, and then realizes the OPGW optical cable outside to wall
Protection；Meanwhile waterproof closure processing is done by the two ends to Flame-retardant PVC plastic pipe, and then realize Flame-retardant PVC plastic pipe
And the waterproof effect of connector well.
5. by the way that more than one cable frame is arranged in connector well, remaining cable frame can be used to store optical cable extra in connector well, into
And optical cable extra in connector well is made to obtain reasonably optimizing layout, to improve its security performance.
