Provide case study on implementation explanation the utility model innovation below.Fig. 3 is the novel method figure that carries out optical cable welding on shaft tower 6, and Fig. 4 is the example schematic of the novel setting of optical cable welding on the utility model shaft tower.
The first optical cable 4 to 500kV the first transformer station 1 is connected to shaft tower 6, then draw down to the more than first cable box 11 along shaft tower 6, after being wound around in cable box 11, cause the first connector box 7 more than first, in the first connector box 7, the second optical cable 5 of the part fibre core of optical cable and 500kV second transformer station's direction is carried out to welding, thereby form the optical cable path of the first transformer station-the second transformer station.By the 3rd optical cable 8 is set, by the five terminal of the 3rd optical cable 8 and the second end, first, connector box 7 is interior is connected, and the 6th end and the 7th end are in the interior welding of the second connector box 10.So-called the 3rd optical cable 8 in the utility model, can be physically with the first optical cable 4 mutually completely distinguish optical cable, can be to be also physically the remainder fibre core of the first optical cable 4.In the present embodiment, be exemplified as the remainder fibre core of the first optical cable 4.Certainly, those skilled in the art also can arrange the optical cable of the 3rd optical cable 8 for physically distinguishing completely mutually with the first optical cable 4, are connected with the first optical cable 4 by modes such as weldings.In the present embodiment, be exemplified as the remainder fibre core of the first optical cable 4, the residue fibre core of the first optical cable 4 in the first connector box 7, convert the 3rd optical cable 8 to and be connected to the second connector box 10 for distant view engineering reserved.In the time of the first newly-built 220kV outlet to the three transformer station of transformer station, need to build the optical cable path of the first transformer station-tri-transformer stations.When engineering construction, need open the second connector box 10, by reserved first transformer station's direction preliminary engineering fibre core and the 3rd transformer station's direction the 4th optical cable 9 weldings, the optical cable path of formation the first transformer station-tri-transformer stations.
The optical fiber splicing method that provides the fiber optic communications system based on same tower mixed pressure multiloop system below, comprises the steps:
Step 1: first open the first connector box 7, the second end and the 3rd end, in the interior welding of the first connector box 7, in the interior welding of the first connector box 7, are drawn by the 6th end five terminal and the second end from the first connector box 7, more closed the first connector box 7;
Step 2: open the second connector box 10, the 6th end is arranged in the second connector box 10, close the second connector box 10;
Step 3: when need to be from the communication port of the first three transformer stations of transformer station to the, the second connector box 10 be opened, by the 6th end and the 7th end in the interior welding of the second connector box 10, more closed the second connector box 10.
Again taking another embodiment explanation: current period engineering is as the 500kV outlet engineering of the first transformer station-the second transformer station, establish 1 36 core OPGW(Optical Fiber composite overhead Ground Wire optical cable with coil holder), wherein 18 cores are special for current period 500kV circuit, and all the other 18 cores are the reserved fibre core of the 220kV outlet engineering of distant view the first transformer station-tri-transformer stations.Fig. 4 is the novel method example schematic of optical cable welding on shaft tower 6, the first optical cable 4 is the OPGW optical cable (as the first optical cable 4) of 1 36 core of first transformer station's direction, this OPGW optical cable carries out welding by the second optical cable 5 of 1-18 fibre core and second transformer station's direction in the first connector box 7, thereby forms the fiber channel of the first transformer station-the second transformer station.While using remaining 19-36 fibre core (as the 3rd optical cable 8) and the 4th optical cable 9 weldings, is then accessed the 4th optical cable 9 second the second connector box 10 in the first connector box 7, is that the distant view 220kV outlet engineering of the first transformer station-tri-transformer stations is reserved.In the time implementing distant view 220kV line project, only need open optical cable the second connector box 10, the optical cable of the 4th optical cable 9 and the 3rd transformer station's direction (i.e. the 3rd optical cable 8) is carried out to welding, thereby form the fiber channel of the first transformer station-tri-transformer stations.
Novel optical fiber welding process in the fiber optic communications system based on same tower mixed pressure multiloop system the utility model proposes has following significant advantage:
1), in the time implementing distant view engineering, only need open the second connector box 10.Because do not need to open the first connector box 7, so the 500kV circuit putting into operation early stage does not need power failure, so this method economical, societal benefits are remarkable;
2) between the first transformer station-the second transformer station, 500kV circuit optical fiber along the line generally all carries trunk circuit information above the provincial level.The utility model has ensured that the optical cable welding in distant view engineering can not affect the normal operation of trunk circuit above the provincial level.
Can find out from the description of above-mentioned optical cable welding novel method, when the utility model distant view engineering construction, not need to open preliminary engineering the first connector box 7, so can not impact the normal operation of preliminary engineering, ensure the stability of electric system.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
