Abstract
Description
Technical Field
[0001] This utility model relates to the field of overhead ground wire optical cable technology, specifically to an optical fiber composite overhead ground wire. Background Technology
[0002] In modern power systems, optical fiber composite overhead ground wires (OPGWs) play a crucial role. They not only perform the lightning protection and grounding functions of traditional overhead ground wires but also possess optical communication capabilities, making them a key infrastructure for the intelligent and information-based transformation of power systems. With the rapid development of the power industry, the performance requirements for OPGWs are also increasing. Especially in complex power grid environments, OPGWs need to be able to more accurately identify and manage different optical fiber channels to meet the growing communication and power grid operation monitoring needs. The development of a patented full-spectrum optical fiber composite overhead ground wire has emerged to address this need, aiming to improve the performance and functionality of OPGWs through innovative technologies, providing strong support for the stable operation and efficient communication of power systems.
[0003] Currently, all manufacturers on the market are replacing black optical fibers with natural-colored ones. This makes it difficult for workers to quickly and accurately identify and distinguish different optical fibers during construction, maintenance, and repair, greatly reducing work efficiency and increasing the risk of communication failures and power grid operation caused by misconnection or misjudgment of optical fibers. Utility Model Content
[0004] Therefore, this utility model provides an optical fiber composite overhead ground wire to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A fiber optic composite overhead ground wire includes an optical cable body.
[0006] The optical cable body contains multiple optical fibers, and the outer surface of each optical fiber is colored with different colored layers.
[0007] The optical cable body has two limiting structures installed inside for limiting the position of multiple optical fibers. The limiting structures include identification plates for labeling different optical fibers.
[0008] Furthermore, an optical fiber sensor for monitoring the optical fiber is installed inside the optical cable body, and the optical fiber sensor has slots on both sides.
[0009] Furthermore, an outer twisted wire layer is provided on the outside of the optical cable body.
[0010] Furthermore, the limiting structure includes an insulating sleeve, which is a semi-circular plate. One side of the insulating sleeve has multiple fiber limiting grooves for limiting the fiber, and the identification plate is located on one side of the fiber limiting groove.
[0011] Furthermore, the insulating sleeve has a plug that engages with the card slot on the side facing the fiber optic sensor.
[0012] Furthermore, the outer wall of the insulating sleeve is equipped with a plurality of elastic metal sheets, the elastic metal sheets being V-shaped plates, and the opening directions of two adjacent elastic metal sheets being opposite. One side of the elastic metal sheet is equipped with an arc-shaped plate that abuts against the inner wall of the optical cable body, and the outer wall of the arc-shaped plate is roughened.
[0013] This utility model has the following advantages: This invention, by setting different colors on the surface of different optical fibers, enables workers to quickly and accurately identify and distinguish different optical fibers during construction, maintenance, and repair, greatly improving work efficiency and reducing communication failures and power grid operation risks caused by misconnection or misjudgment of optical fibers. Furthermore, the identification tags allow workers to quickly and accurately identify and distinguish different optical fibers even when the colors on the fibers are faded and difficult to distinguish. The limiting structure facilitates the differentiation of multiple optical fibers and protects them from damage when the optical cable itself shakes, preventing damage to the end of the fiber optic cable near the fiber optic sensor.

[0020] Please see Figures 1-4 This utility model provides an optical fiber composite overhead ground wire, including an optical cable body 1, with multiple optical fibers 2 disposed inside the optical cable body 1. The outer surface of the optical fibers 2 is colored with a colored layer 21, and different optical fibers are colored differently. This utility model can use 12 international standard colors (blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, and cyan) to color each optical fiber, so that during construction, maintenance and repair, the staff can quickly and accurately identify and distinguish different optical fibers, which greatly improves work efficiency and reduces communication failures and power grid operation risks caused by misconnection or misjudgment of optical fibers.
[0021] The optical cable body 1 has two limiting structures 4 installed inside for limiting multiple optical fibers 2, and the two limiting structures 4 are set facing each other. The limiting structure 4 includes a label 43 for marking different optical fibers 2. When the optical fiber has been used for a long time, the color on the optical fiber will fade, making it difficult to distinguish between multiple colors. In this invention, when installing optical fibers, each color of optical fiber corresponds to a label 43. When the color on the optical fiber is difficult to distinguish due to fading, the staff can quickly and accurately identify and distinguish different optical fibers through the label 43.
[0022] The optical cable body 1 is equipped with an optical fiber sensor 3 for monitoring the optical fiber. The optical fiber sensor 3 is a distributed scattering type optical fiber sensor. Multiple optical fiber sensors 3 are connected in series on the optical fiber 2. Through OTDR and OFDR technologies, the changes in temperature and strain at different positions along the optical fiber are detected. An additional circuit is connected in the junction box to power the sensor and transmit data. It can monitor parameters such as temperature and attenuation of the optical fiber in real time. If the parameters are abnormal, the power operation and maintenance personnel can take measures to troubleshoot the fault in the first time, so as to ensure the smooth power communication and the safe and stable operation of the power grid.
[0023] The optical cable body 1 is provided with an outer twisted wire layer 5, and the optical fiber sensor 3 has card holes 31 on both sides for limiting the limiting structure 4.
[0024] The limiting structure 4 includes an insulating sleeve 41, which is a semi-circular plate. One side of the insulating sleeve 41 is provided with multiple fiber limiting grooves 42 for limiting the fiber 2. The identification plate 43 is located on one side of the fiber limiting groove 42. When the two insulating sleeves 41 are set facing each other, the fiber limiting grooves 42 on the two insulating sleeves 41 are staggered, which facilitates the separation of different fibers.
[0025] An insert 44 is installed on the side of the insulating sleeve 41 facing the fiber optic sensor 3, which engages with the locking hole 31. When the insert 44 is inserted into the locking hole 31, the insulating sleeve 41 is made of rubber, so that when the optical cable body 1 shakes, the optical fiber 2 inside the optical cable body 1 is less likely to break at the interface of the optical fiber sensor 3 due to torsion. Multiple elastic metal plates 45 are installed on the outer wall of the insulating sleeve 41. The elastic metal plates 45 are V-shaped plates, and the opening directions of two adjacent elastic metal plates 45 are opposite. The elastic metal plates 45 are made of aluminum alloy. An arc-shaped plate 46 is installed on one side of the elastic metal plate 45, which abuts against the inner wall of the optical cable body 1. The outer wall of the arc-shaped plate 46 is roughened, which increases the friction between the arc-shaped plate 46 and the inner wall of the optical cable body 1, so that the limiting structure 4 is less likely to shift within the optical cable body 1. When the optical cable body 1 shakes, the multiple elastic metal plates 45 provide cushioning to prevent the optical cable body 1 from being squeezed and damaged.
[0026] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
