Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the present invention will be described in detail, and following examples are explanation of the invention, and the present invention is not limited to following execution mode.
As shown in Figure 1, the OPGW Lightning Proof for Optical Cables be installed on parapet provided by the invention hits device, comprises OPGW optical cable 3, insulator 2, remaining cable frame 11, OPGW cable splice closure 12.OPGW optical cable 3 top is fixed on parapet 1 by insulator 2, the downlead redundance of OPGW optical cable 3 is wrapped on remaining cable frame 11, the downlead end of OPGW optical cable 3 is connected to OPGW cable splice closure 12, and remaining cable frame 11 and OPGW cable splice closure 12 are fixedly mounted on parapet 1.
OPGW optical cable 3 top is by earth connection 5 ground connection, earth connection 5 one end connects OPGW optical cable 3, the other end by a parallel groove clamp 6 and the earth electrode 4 be arranged on parapet 1 is connected, earth connection 5 is bolted with earth electrode 4 by crimping copper aluminium terminal, energy effective guarantee leakage current.The OPGW optical cable 3 of remaining cable frame 11 front end is by No. two earth connection 8 ground connection, and No. two earth connection 8 one end are connected with OPGW optical cable 3 by No. two parallel groove clamps 7, and the other end is connected with lightning protection grounding network 10 by No. three parallel groove clamps 9.The position winding aluminum band contacted with No. three parallel groove clamps 9 of lightning protection grounding network 10, in case the reinforcing bar rugosity of lightning protection grounding network 10 is inadequate, and can not good earth.In reinforcing bar and the earth connection junction of lightning protection grounding network 10, all derust with sand papering, guarantee that ground connection is good.An earth connection 5 and No. two earth connections 8 all can adopt the naked aluminum conductor material of 100 ~ 130mm, optimum adopt the naked aluminium of 120mm, soft or hard appropriateness, easily bend, be convenient to install, and can reach the requirement of thunder and lightning leakage current, ensure the smooth and easy inflow underground of electric current.
A parallel groove clamp 6 is all not less than 4000mm with the contact area of OPGW optical cable 3, No. two parallel groove clamps 7 with the contact area of OPGW optical cable 3 and the contact area of No. three parallel groove clamps 9 and lightning protection grounding network 10
2, parallel groove clamp is fully contacted with OPGW optical cable 3, lightning protection grounding network 10, avoids parallel groove clamp excessive heating and burn out optical cable.
Parallel groove clamp is one of weakest link of communication network operation, when the maximum temperature that parallel groove clamp place temperature can bear more than OPGW optical cable 3, will cause the overheated fault such as even on fire in junction, the reliability of parallel groove clamp will directly have influence on the reliability of communication network.But, parallel groove clamp surface irregularity makes that contact resistance is excessive, surface oxidation, running overload, and wind, vibrations etc. cause the holding screw of parallel groove clamp loosen and make the factors such as parallel groove clamp contact resistance increase, parallel groove clamp contact-making surface all can be made to produce amount of heat, there is potential safety hazard, therefore should monitor the temperature of parallel groove clamp in real time, prevent trouble before it happens.
As shown in Figure 2, this lightning protection device also comprises parallel groove clamp device for detecting temperature, a parallel groove clamp 6 arranges a temperature sensor 13, No. two parallel groove clamps 7 are arranged No. two temperature sensors 14, No. three parallel groove clamps 9 are arranged No. three temperature sensors 15, a temperature sensor 13, No. two temperature sensors 14, No. three temperature sensors 15 are electrically connected with controller 16 respectively, and controller 16 is electrically connected with wireless communication device 17.Temperature sensor detects the temperature of parallel groove clamp in real time, and detection signal is passed to controller 16, temperature signal is passed to host computer by wireless communication device 17 by controller 16, monitor for staff, namely report to the police if temperature exceedes early warning value, staff can deal with in time, and to avoid, parallel groove clamp temperature is too high burns out circuit.This device for monitoring temperature structure is simple, and cost is low, monitors easily and effectively.
The preferred embodiment of the present invention is only above; but the present invention is not limited thereto; any those skilled in the art can think there is no creationary change, and some improvements and modifications done without departing from the principles of the present invention, all should drop in protection scope of the present invention.
