Description
Technical field
The present invention relates to ultra-high-tension power transmission line field, particularly relate to enter under a kind of distribution building OPGW optical cable draws
Stand method.
Background technology
(Optical Fiber Composite Overhead Ground Wire optical fiber is multiple for OPGW optical cable
Close aerial earth wire), refer to optical fiber is placed in the ground wire of aerial high voltage power line, in order to constitute transmission of electricity
Fiber optic communication network on circuit, it has the dual-use function of common aerial earth wire and communications optical cable, therefore
It is widely used in power system.OPGW optical cable, when introducing distribution building, fixes OPGW optical cable
The strain insulator-string ground wire of strain insulator-string needs to connect with the ground wire on roof, distribution building, and OPGW can not directly enter
Entering distribution building, it must be with the guiding cable connection of communication room, to form fiber-optic communications traffic pipeline.
At present, the OPGW optical cable introducing method that enters the station in existing distribution building typically uses OPGW optical cable upwards
After climbing over parapet, the connector box transfer changing-over arranged inside parapet is continuous guides optical cable, then exists
The roof pipe laying through walls in distribution building, guides optical cable and enters distribution building by pipeline, and stride across in distribution building
Access communications room, space, portion or secondary device room.In the method the most exposed outside because of connector box, enter
And make under the Environmental security reliability that continues between OPGW optical cable and guiding optical cable.Meanwhile, in tradition
Distribution building body of wall in, because not considering to introduce OPGW optical cable, and then on roof, distribution building the most in advance
Doing pipe laying through walls design, the cable floor being in addition provided with guiding optical cable is generally located on the end in distribution building
Layer, this results in OPGW optical cable and can not carry out conversion with the guiding optical cable in communications equipment room and continue；Meanwhile,
If follow-up pipe laying through walls on roof, the integral house structure in distribution building can be impacted, Jin Erzao
Become the technological deficiency that security performance reduces.Therefore the distribution building of pipe laying through walls design is not made for roof,
The most safe and reliable realize the introducing of entering the station of OPGW optical cable and become nowadays problem demanding prompt solution.
Summary of the invention
During to this end, the technical problem to be solved in the present invention is to overcome the OPGW optical cable of prior art to enter the station
Because the connector box in conventional electrical distribution building is exposed outside, roof is not made pipe laying through walls design and cannot be drawn simultaneously
The technological deficiency entered, thus provide a kind of safe and reliable distribution building OPGW optical cable to enter the station under drawing method.
To achieve these goals, the present invention provides a kind of distribution building OPGW optical cable to enter the station under drawing method,
Comprise the steps:
