[0064] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0065] With reference to the following description and accompanying drawings, specific embodiments of the present application are disclosed in detail, indicating the manner in which the principles of the present application can be employed. It should be understood that the embodiments of the present application are not limited in scope. Within the spirit and scope of the appended claims, the embodiments of the present application include many variations, modifications and equivalents.

[0066] Features described and / or illustrated with respect to one embodiment may be used in the same or similar manner in one or more other embodiments, combined with features in other embodiments, or substituted for features in other embodiments.

[0067] It should be emphasized that the term "include / comprising" when used herein refers to the presence of features, integers, steps or components, but does not exclude the presence or addition of one or more other features, integers, steps or components.

[0068] At present, there are mainly two types of overhead ground wires for 110kV and above transmission lines: ordinary ground wires and fiber-optic composite ground wires. Based on lightning protection and communication considerations, overhead ground wires mostly adopt a base-by-base grounding method. Due to the electromagnetic induction between the overhead ground wire and the conductor, a large induced current is generated in the overhead ground wire.

[0069] First, overhead ground wires are installed above transmission lines to protect them from direct lightning strikes. As the coverage of overhead transmission lines continues to expand, the probability of lightning strikes on transmission lines is also increasing. Installing overhead ground wires on transmission lines can reduce lightning accidents and improve the safety of line operations. Overhead ground wires are installed above the protected conductors and equipment. When thunderclouds appear above the lines and discharge to the ground, the lightning channel is likely to strike the overhead ground wires. The lightning current is then directed into the earth through the overhead ground wire's grounding wire or the metal tower itself, protecting the transmission line from power failure. In recent years, it has been discovered that when fiber-optic composite overhead ground wires are struck by lightning, they can suffer mechanical damage, leading to malfunctions in fiber-optic communications.

[0070] Furthermore, due to the complex and ever-changing operating environment, the fiber-optic composite overhead ground wire and the three-phase current carrier form a spatially parallel multi-conductor system. Due to the electromagnetic coupling effect between the conductors in this system, changes in the current in the three-phase current carrier induce a corresponding electromotive force in the fiber-optic composite overhead ground wire, which in turn forms an induced current. When the line is impacted by the induced current, the current jumps, causing the metal strands to soften, melt, anneal, and break. Simultaneously, the temperature of the optical unit rises sharply. If the temperature rise lasts long enough and reaches a certain level, the fiber-optic composite overhead ground wire cannot withstand the full short-circuit current, resulting in an asymmetric short-circuit fault. This seriously affects the transmission performance of the optical fiber, causing increased fiber attenuation and dispersion changes, which in turn threatens the quality of communication signals and may even damage or break the optical fiber core, severely impacting power communication and grid security.

[0071] The details are described in detail through the following embodiments.

[0072] In order to avoid asymmetric short circuit faults and improve the reliability of optical cable communication, this embodiment provides a hardware suitable for fusion arrangement of optical cable conductors, such as Figures 1 to 4 As shown, it specifically includes the following contents:

[0073] Strain fittings 1, suspension fittings 2 and first spacer 3; one end of the strain fittings is connected to the first insulator string 5, and the other end is connected to the cable 6 in the gear; the cable in the gear passes through the first spacer; the cable in the gear includes: a first split conductor 6-1 and a first optical cable 6-2 arranged on its central axis; the suspension fitting 2 includes: a connecting plate 2-1, a first fixed support wire clamp 2-3 connected thereto and a plurality of suspension wire clamps 2-2; the second split conductor 7 passes through the suspension wire clamp and the suspension wire clamp grips the second split conductor; the top of the connecting plate is connected to the second insulator string 8, and the bottom is provided with an opening 2-5, the first fixed support wire clamp is arranged in the opening, and the second optical cable 9 passes through the opening via the first fixed support wire clamp; the second optical cable is arranged on the central axis of the second split conductor.

[0074] Specifically, the optical cable, the first optical cable, and the second optical cable can all be fiber-optic composite overhead ground wires; the fiber-optic composite overhead ground wire is arranged on the central axis of the split conductor. The first insulator string can be a horizontally arranged insulator string, one end of which can be connected to the base tower and the other end to the tension fitting. The second insulator string can be a suspension insulator string or a jumper insulator string, one end of which can be connected to the base tower, and the bowl-shaped hanging plate at the other end of the second insulator string can be connected to the top of the connecting plate. The cable within the section can represent the cable segment between two adjacent base towers. The first split conductor can represent the split conductor in the cable within the section, and the first optical cable can represent the optical cable in the cable within the section. The first fixed support clamp can represent the main fixed support clamp for the optical cable in the suspension fitting. The second split conductor can represent the split conductor in a jumper bundle, and the second optical cable can represent the optical cable in the jumper bundle. The first spacer can represent the spacer through which the cable within the section passes. There can be multiple first spacers, and they can be arranged on the cable within the section as needed. The connecting plate can be a dedicated small-man connecting plate. The split conductors may be single-phase conductors. It is understandable that the tension fittings, suspension fittings and first spacer bars in the fittings suitable for fusion arrangement of optical cable conductors are all made of metal.

[0075] Preferably, the first split conductor and the second split conductor are both four-split conductors, and there are four suspension clamps, which are fixedly connected to the suspension holes of the connecting plate; the four sub-conductors in the second split conductor pass through each of the suspension clamps respectively.

[0076] As can be seen from the above description, in this embodiment, the optical cable is arranged on the central axis of the split conductor, allowing the optical cable to be arranged in the center of the single-phase conductor along the direction of the transmission line, thereby avoiding optical fiber communication failures caused by lightning strikes, severe ice disasters, etc. Hardware suitable for the fusion arrangement of optical cables and conductors is installed on the split conductors, and the optical cable is gripped by a first fixed support clamp. The first fixed support clamp and the conductor are at the same potential. The first fixed support clamp is made of aluminum alloy and is connected to the optical cable and the connecting plate. Therefore, the conductor, connecting plate, and optical cable are at the same potential, which can avoid the generation of induced electricity and protect the optical cable from the mechanical and electrical performance aspects.

[0077] In order to withstand the full tension of the optical cable and meet the electrical performance requirements, such as Figure 5 and Figure 6 As shown, in one embodiment, the tension fitting 1 includes: a special connecting plate 1-1, a connecting fitting assembly 1-2 and a tension clamp 1-3 connected in sequence; one end of the special connecting plate is connected to the first insulator string, and the other end is connected to the first split conductor and the connecting fitting assembly; the tension clamp is connected to the first optical cable.

[0078] Specifically, one end of the special connecting plate is connected to the bowl head hanging plate of the first insulator string; the special connecting plate can be an isosceles triangular prism connecting plate, the top corner side edge of the isosceles triangular prism connecting plate can be connected to the first insulator string, and the bottom corner side edge of the isosceles triangular prism connecting plate can be connected to the first split conductor; the connecting hardware can be connected to the center position of the side surface composed of each bottom corner side edge, and the connecting hardware assembly is located at the center of the split conductor, that is, on the center axis. The top corner side edge refers to the edge connecting the two isosceles triangle vertices in the isosceles triangular prism connecting plate. The tension clamp can be a pre-twisted optical cable tension clamp. In order to facilitate the installation of the first optical cable, the main body frame of the first spacer rod can be provided with an opening. In order to protect the first optical cable, the optical cable is wrapped with a protective wire at the clamping position of the first fixed support clamp, and the protective wire can be a double-layer optical cable pre-twisted wire protective wire.

[0079] Preferably, the first split conductor is a four-split conductor, two of which can be connected to a hanging hole at one bottom corner of the isosceles triangle connecting plate via a first hardware fixture, and the other two of which can be connected to a hanging hole at another bottom corner via a second hardware fixture. The first hardware fixture and the second hardware fixture can be arranged in parallel, with the first hardware fixture connecting the two sub-conductors to the hanging hole at one bottom corner, and the second hardware fixture connecting the other two sub-conductors to the hanging hole at another bottom corner. The second split conductor can be connected to the first and second hardware fixtures, and the second optical cable can be connected to the tension clamp.

[0080] In order to realize the clamping and positioning of the split conductors and the optical cable, on the basis of realizing the support of the optical cable, further ensure the equipotential between the optical cable and the conductor, avoid the generation of induced electricity, and protect the optical cable from the mechanical and electrical performance. Figure 7 and Figure 8 As shown, in one embodiment, the first spacer comprises:

[0081] A main body frame 3-1, a second fixed support clamp 3-2 arranged at the center of the main body frame, and a plurality of wire clamps 3-3 arranged around the periphery of the main body frame, the second fixed support clamp and the wire clamps are both fixedly connected to the main body frame; the first optical cable 6-2 passes through the second fixed support clamp 3-2, the second fixed support clamp 3-2 holds the first optical cable 6-2, and the first split wire passes through the wire clamp.

[0082] Specifically, the second fixed support clamp is a fixed support clamp in the first spacer. The main body frame can represent a split slotted conductor spacer; preferably, the main body frame is a rectangular frame, such as a square frame, and the second fixed support clamp is arranged at the center of the rectangular frame and can be fixedly connected to the rectangular frame by a metal connecting rod. The first split conductor is a four-split conductor, and the four corners of the rectangular frame are connected to the conductor clamps. The sub-conductors of the four split conductors pass through each conductor clamp respectively. For example, the four sub-conductors are A1 to A4 in sequence, and the four conductor clamps are B1 to B4 in sequence. Then A1 can pass through B1, A2 through B2, A3 through B3, and A4 through B4. The first spacer is made of metal. The first spacer is connected to the first optical cable and the first split conductor at the same potential. The first optical cable, the first split conductor and the first spacer are at the same potential, which can further avoid the generation of induced electricity and protect the optical cable from the mechanical and electrical performance. The part of the first optical cable gripped by the second fixed support clamp can be wrapped with a double-layer twisted wire protective bar.

[0083] In order to realize the connection and splicing of optical fibers on the optical fiber transmission line, ensure the stable transmission of optical fiber signals, and realize the arrangement of optical fiber splice boxes between the various sub-conductors of the split conductors, so as to improve the lightning protection and discharge corona effect, such as Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, in one embodiment, the hardware suitable for the fusion arrangement of optical cable conductors further includes: an integrated splicing box 4, the integrated splicing box 4 includes: a second spacer rod 4-1, an optical fiber splicing box 4-2 and a connection support seat 4-3; the second spacer rod is connected to the optical fiber splicing box via the connection support seat.

[0084] Specifically, the second spacer can be a wire spacer connected to the connection support base, and the structure of the second spacer can be the same as that of the first spacer, which will not be described in detail. The upper end of the body frame of the second spacer can be fixedly connected to the connection support base.

[0085] In order to achieve the connection of the first optical cable, in one embodiment, the cable in the gear passes through the second spacer rod, and the connection point of the first optical cable is located in the connection support seat.

[0086] Specifically, the first optical cable may be formed by connecting a plurality of optical cables. The way in which the conductors and optical cables pass through the second spacer rods may be the same as the way in which the conductors and optical cables pass through the first spacer rods, which will not be described in detail here.

[0087] In order to achieve the connection of the second optical cable, in one embodiment, the second split conductor and the second optical cable pass through the second spacer rod, and the connection point of the second optical cable is located in the connection support seat.

[0088] Specifically, the second optical cable may be formed by connecting a plurality of optical cables. The way in which the conductors and the optical cables pass through the second spacer rods may be the same as the way in which the conductors and the optical cables pass through the first spacer rods, which will not be described in detail here.

[0089] In order to achieve excess cable processing, in one embodiment, the hardware suitable for the fusion arrangement of optical cable conductors further includes: an excess cable rack; the excess cable rack is used to collect the excess cables of the first optical cable and / or the excess cables of the second optical cable.

[0090] Specifically, if the optical cable length exceeds the actual requirement, the excess cable can be cut to avoid the impact of the excess cable, or other methods can be used, such as setting up an excess cable rack to achieve excess cable processing. The structure of the excess cable rack can be an existing excess cable rack structure, such as a cross-shaped excess cable rack, and the layout position can be set according to actual needs.

[0091] In order to improve the reliability of the hanging hardware, such as Figure 3 and Figure 4 As shown, in one embodiment, the suspension hardware further includes: a U-shaped weight piece 2-6, which is arranged on both sides of the connecting plate. The suspension hardware may also include: a third fixed support wire clamp 2-4, which is fixedly arranged on the outside of the U-shaped weight piece.

[0092] Specifically, the third fixed support clamp may be a cable side fixed support clamp.

[0093] In order to further illustrate the present solution, the present application provides an application example of hardware suitable for the fusion arrangement of optical cables and conductors. In this application example, the split conductor is a four-split conductor, and the hardware suitable for the fusion arrangement of optical cables and conductors includes: integrated optical cable / conductor tension fittings, integrated optical cable / conductor suspension fittings, integrated optical cable / conductor spacers, integrated optical cable / conductor excess cable racks, and integrated optical cable / conductor junction boxes. Among them, the functions achieved by the integrated optical cable / conductor tension fittings can be equivalent to the functions achieved by the above-mentioned tension fittings, the functions achieved by the integrated optical cable / conductor suspension fittings can be equivalent to the functions achieved by the above-mentioned suspension fittings, the functions achieved by the integrated optical cable / conductor spacers can be equivalent to the functions achieved by the above-mentioned first spacers, the functions achieved by the integrated optical cable / conductor excess cable racks can be equivalent to the functions achieved by the above-mentioned excess cable racks, and the functions achieved by the integrated optical cable / conductor junction boxes can be equivalent to the functions achieved by the above-mentioned junction boxes.

[0094] 1. The integrated optical cable / conductor tension fittings are designed to keep the optical cable in the center of the four-split conductor while bearing the full tension of the optical cable and meeting electrical performance requirements. They include: dedicated connecting plates, connection fitting components, and pre-twisted optical cable tension clamps.

[0095] Specifically, the dedicated connector plate is one of the connectors in the four-wire conductor string. It has a reserved connection hole that connects to the connector assembly of the integrated cable / conductor tensioning hardware, positioning the connector assembly at the center of the four-wire conductor. The connector assembly's load must meet the cable tension requirements, and its length is determined by the position of the pre-twisted cable tension clamp. The pre-twisted cable tension clamp bears the full tension of the cable, guiding it down to the jumper bundle while ensuring that the cable is positioned at the center of the conductor down conductor.

[0096] Specifically, after the laying out of the four-split conductors of the transmission line is completed, the optical cable is laid out. At the starting end of the laying out, the connecting hardware assembly of the optical cable / conductor integrated tension hardware is connected to the reserved connection hole of the special connecting plate to realize the positioning of the hanging point of the optical cable / conductor integrated tension hardware. The length of the connecting hardware assembly is adjusted according to the distance from the conductor tension clamp to the special connecting plate, so that after the pre-twisted tension clamp is installed, the optical cable down lead is located in the center of the four-split conductor and can be led down at the same time as the four-split conductor. Similarly, at the other end of the optical cable within the span, the installation of the optical cable / conductor integrated tension hardware 1 is completed.

[0097] 2. The integrated optical cable / conductor suspension fittings are connected to the suspension insulator string or jumper insulator string, and simultaneously carry the four-split conductors and the optical cable in the middle, including: a special small connecting plate, a suspension clamp, a main fixed support clamp for the optical cable, a side fixed support clamp for the optical cable, a pre-twisted wire protection bar for the optical cable, and a U-shaped weight.

[0098] Specifically, the upper end of the special man-made connecting plate is connected to the bowl-head hanging plate of the insulator string, and the four hanging holes are connected to the hanging wire clamps, while the bottom end is slotted and the main fixed support wire clamp of the optical cable is installed. In order to prevent the main fixed support wire clamp of the optical cable from damaging the optical fiber skeleton inside the optical cable, the optical cable sheathing bar is designed to be double-layered. The optical cable wrapped with the double-layer sheathing bar is then clamped into the main fixed support wire clamp of the optical cable. At this time, the optical cable is located in the center of the four-split conductor. The integrated optical cable / conductor suspension hardware not only meets the mechanical load requirements of the conductors and optical cables, but also meets the grip requirements and electrical requirements of the two. According to the string type requirements, U-shaped weights are designed and installed on both sides of the special man-made connecting plate. At the same time, optical cable side fixed support wire clamps are also designed and installed on the outside of the U-shaped weight to support and fix the optical cables on both sides of the main fixed support wire clamp of the optical cable to prevent external interference from damaging the optical cable and the U-shaped weight.

[0099] Specifically, the integrated optical cable / conductor suspension fittings are installed at the lower end of the suspension insulator string or the jumper insulator string. The special man-shaped connecting plate is connected to the bowl head hanging plate under the insulator, and four suspension clamps are suspended in the four-split suspension holes to achieve the supporting effect of the four-split conductors. After the optical cable is wrapped with a double-layer pre-twisted wire protective strip, enter the interior from the notch on the lower side of the special man-shaped connecting plate (which can be equivalent to the above-mentioned opening), and then install the main fixed support clamp of the optical cable to complete the fixation of the optical cable. According to actual needs, if a U-shaped weight piece needs to be installed, install it on both sides of the special man-shaped connecting plate, and then install the side fixed support clamp of the optical cable on the outside of the U-shaped weight piece to achieve support and fixation of the optical cable.

[0100] 3. The optical cable / conductor integrated spacer is arranged within the span to complete the clamping and positioning of the split conductor and the optical cable, which not only supports the optical cable, but also achieves the equipotentiality of the optical cable and the conductor, avoids the generation of induced electricity, and protects the optical cable from the mechanical and electrical performance.

[0101] Specifically, the integrated optical cable / conductor spacer includes: a four-split slotted conductor spacer, an optical cable fixing and supporting wire clamp, and a wire clamp chuck. The wire clamp chuck of the four-split slotted conductor spacer is used to clamp the split conductors. The double-frame plate is slotted at the bottom to facilitate the insertion of the optical cable. The connecting plate of the optical cable fixing and supporting wire clamp is arranged between the slotted double-frame plates. The optical cable is wrapped with a double-layer pre-twisted wire sheath and then clamped into the optical cable fixing and supporting wire clamp. The functions achieved by the four-split slotted conductor spacer can be equivalent to the functions achieved by the above-mentioned main body frame, the functions achieved by the wire clamp chuck can be equivalent to the functions achieved by the above-mentioned conductor clamp, and the functions achieved by the optical cable fixing and supporting wire clamp can be equivalent to the functions achieved by the above-mentioned second fixed and supporting wire clamp.

[0102] Specifically, the optical cable / conductor integrated spacers are arranged within the span. The installation of the four-split conductors is completed first, and then the optical cable is installed. The optical cable / conductor integrated spacers are arranged at intervals according to the requirements of the construction drawings.

[0103] 4. The function of the integrated optical cable / conductor excess cable rack is to store excess optical cables. It is installed and fixed on the split conductors. It can be arranged within the conductor span or in the jumper string. The installation position is selected according to actual needs to ensure the position stability of the optical cable inside the four-split conductor and the long-term stable and orderly storage of excess optical cables.

[0104] 5. The optical cable / conductor integrated splice box includes: conductor spacer, optical fiber splice box and connection support seat.

[0105] The conductor spacers are clamped on the split conductors and serve as the clamping and fixing points for the optical fiber splice box. The function of the optical fiber splice box is to realize the connection and splicing of optical fibers on the optical fiber transmission line and ensure the stable transmission of optical fiber signals. The connection support seat is designed to realize the fixation between the optical fiber splice box and the conductor spacers, so that the optical fiber splice box can be arranged in line between the four split conductors, which has a good lightning and discharge corona effect and ensures the safety of optical fiber communication. An optical cable / conductor integrated spacer is arranged on both sides of the optical cable / conductor integrated splice box to ensure the stability of the position of the incoming and outgoing optical cables. The optical cable / conductor integrated splice box can be arranged within the span or in the jumper bundle, depending on actual needs. First, the optical cable / conductor integrated splice box is fixed on the four split conductors, and a set of optical cable / conductor integrated spacers are installed on both sides to clamp and fix the spliced ​​optical cables respectively, and finally the splicing of the spliced ​​optical cables in the optical fiber splice box is completed.
