Description
Technical Field

1. With the rapid development of the national electric power smart grid and the electric power internet of things, the electric power communication network plays a key role in the smart grid and the electric power internet of things as a transmission channel and service intellectualization, and an optical cable on a high-voltage line is a foundation and an important skeleton of the electric power communication network. Under the conventional condition of OPGW optical cable, the length of a production disc is about 5km, the connection position of the OPGW is required to be led down at a tension tower, and then the OPGW optical cable is fixed on a tower body angle steel of which the iron tower is about 10 meters away from the ground by using a clamping plate after the connection of a connecting box for the tower. The tangent tower can not be used as a point for downward connection of the OPGW optical cable, because the tangent tower normally only bears the gravity of the optical cable and does not bear horizontal force, and the optical cable can be supported in the vertical direction only by using a suspension wire clamp when passing through the tangent tower.
2. In recent years, due to the development of intelligent circuits, devices such as forest fire monitoring, wire sag monitoring, wire windage yaw monitoring and video monitoring are installed on a power transmission line iron tower, or an electric power internet of things service in a certain area is accessed in the middle of an OPGW, or a 5G base station of a shared operator is accessed, service or equipment is required to be accessed on a certain iron tower, and in the prior art, after an optical cable of the iron tower is cut off, the OPGW of the previous strain section is laid again, so that enough optical cable length is reserved, and then the service is accessed by adopting a traditional splice box. If the tower is a tangent tower, the tower is firstly transformed, or the triangle is adopted to lead down the optical cable in a mode of matching with the strain clamp, so that the phenomenon of uneven stress of the tangent tower is easily caused, and potential safety hazards exist; the development of the method for the downward connection is particularly important.
3. In addition to the optical fiber splicing and pigtail drop at the tangent tower of the OPGW cable, the limitations of existing OPGW splicing techniques are difficult to address as many difficulties as are:
(1) The method is limited by the influence of terrain, the linear towers are 2km or more frequently, the OPGW split-disk connection becomes a ridge which is difficult to surmount, and the conventional method is that the OPGW split-disk design needs to be considered to be continued in the nearest tension tower, so that the situation of multi-stage split-disk of the line OPGW can be possibly caused, the situation of overlong or too short single optical cable disk can also be possibly caused, and finally, the situation of too many connection points and too great attenuation of the whole optical cable relay section can be caused.
(2) The strain towers of the branch disc connection points are arranged on the mountain top, and at the moment, if the two sides are straight towers, the optical connection points cannot be adjusted. The optical cable coil can only consume a large amount of manpower resources to erect and connect the optical cable coil on the mountain top in a mode of manually backing the mountain top.
(3) The line is often occupied and moved, so that the engineering of changing the path is caused, and the OPGW cannot move along with the line flexibly at the moment, and an optical cable tray of the whole tension-resistant section must be purchased to connect the head-end tension-resistant tower.
(4) When lightning stroke occurs in OPGW, under the condition of broken core, the whole tension-resistant section optical cable is replaced in the existing mode, and then the whole tension-resistant section optical cable is connected with the original OPGW in a head-tail tension-resistant tower.
