Description

Technical Field

[0001] This invention belongs to the field of power transmission line engineering technology, and specifically relates to a smart pole tower with four ground wire lightning protection and communication. Background Technology

[0002] Electric poles are crucial supporting structures for overhead transmission lines. They suspend conductors, insulator strings, and fittings in the air, transferring vertical and horizontal loads to foundations buried deep in the earth. With the gradual expansion of power grid construction, and in response to calls for energy conservation and environmental protection while reducing pole costs, composite crossarm materials are being applied to the fabrication of transmission poles.

[0003] Chinese invention patent application number 201711070918.3 discloses a 110kV short-pole utility pole and its manufacturing method. The pole includes a pole body, a ground wire crossarm, an upper crossarm, a middle crossarm, and a lower crossarm. The upper, middle, and lower crossarms are all connected to the pole body via clamps. The ground wire crossarm includes a lower support, a first ground wire crossarm, and a second ground wire crossarm. The lower support is connected to the upper end of the pole body, and the lower ends of the first and second ground wire crossarms are connected to the lower support. The first and second ground wire crossarms intersect each other, and the intersection is connected by bolts. Both the first and second ground wire crossarms have ground wire mounting plates at their upper ends. By optimizing the structure of the ground wire crossarm, the height of the pole is reduced, saving materials while simultaneously improving the structural strength of the ground wire crossarm.

[0004] However, this 110kV short pole only has two ground wires. As the protection angle of the tower decreases, the lightning protection performance of the tower is improved. However, as the protection angle decreases, the horizontal distance between the two ground wires will inevitably increase. When the horizontal distance between the two ground wires is greater than 5 times the vertical distance between the conductors, the two ground wires cannot be effectively shielded. The traditional double ground wire structure cannot achieve better lightning protection performance. Summary of the Invention

[0005] This invention provides a smart communication pole with four ground wires for lightning protection, which aims to solve the problem that the existing dual ground wire structure cannot achieve better lightning protection performance.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A smart communication pole with four ground wires for lightning protection includes: a pole body, on which a first crossarm, a second crossarm, and a third crossarm are horizontally arranged from bottom to top. The first, second, and third crossarms are symmetrically distributed around the pole body. Insulator strings are installed at the lower ends of both ends of the first, second, and third crossarms, and conductors are installed at the lower ends of the insulator strings. Two extension arms are installed above the third crossarm. The extension arms are inclined upwards in a direction away from the pole body and are symmetrically distributed around the vertical line of the pole body. A dove-shaped ground wire bracket is installed at the top of each extension arm. An inner ground wire fitting is installed on the side of the dove-shaped ground wire bracket closest to the pole body, and an outer ground wire fitting is installed on the side of the dove-shaped ground wire bracket away from the pole body. An inner ground wire is installed on the inner ground wire fitting, and an outer ground wire is installed on the outer ground wire fitting. The height of the inner ground wire is higher than that of the outer ground wire.

[0008] Furthermore, the first crossarm, the second crossarm, and the third crossarm are of the same length, the distance between the outer ground wires is greater than the length of the third crossarm, and the distance between the inner ground wires is less than the length of the third crossarm.

[0009] Furthermore, the angle between the plumb line of the outer ground wire and the line connecting the outer ground wire to the conductor on the adjacent first crossarm is 5°-10°.

[0010] Furthermore, a data box is provided on the upper part of the third crossarm, the data box is communicatively connected to the inner ground wire, a number of first monitoring device groups are provided on each conductor, and a number of second monitoring device groups are provided on the tower body, the first monitoring device groups and the second monitoring device groups are communicatively connected to the data box.

[0011] Furthermore, the first monitoring device group further includes: a distributed fault monitoring device, a micro-wind vibration monitoring device, a conductor icing monitoring device, a conductor temperature monitoring device, a conductor sag monitoring device, a conductor wind deflection monitoring device, and a conductor galloping monitoring device.

[0012] Furthermore, the second monitoring device group further includes: a tower tilt monitoring device, a fitting temperature monitoring device, a micro-meteorological monitoring device, a wildfire monitoring device, a grounding current monitoring device, and a panoramic visualization monitoring device.

[0013] Furthermore, the outer grounding wire hardware further includes: a first trunnion mounting plate, the upper part of which cooperates with the dove-shaped grounding wire bracket, the lower part of which is pinned to a first U-shaped mounting plate, the lower part of which is pinned to a first connecting plate, the first connecting plate being an isosceles triangular flat plate, the apex of which is pinned to the lower part of the first U-shaped mounting plate, the two base corners of which are pinned to first connecting plates, the lower part of which is pinned to a suspension clamp, an outer grounding wire being provided in the two suspension clamps, a first parallel groove clamp being provided on the outer grounding wire, one end of a first grounding wire being connected to the first parallel groove clamp, and the other end of the first grounding wire being introduced into the ground through the tower body.

[0014] Furthermore, the inner grounding hardware further includes: a second trunnion mounting plate, the upper part of which mates with a dove-shaped grounding bracket; a second U-shaped mounting plate pinned to the lower part of the second trunnion mounting plate; an extension plate pinned to the lower part of the second U-shaped mounting plate; a second connecting plate pinned to the lower part of the extension plate; the second connecting plate being an isosceles triangular flat plate; the apex of the second connecting plate pinned to the lower part of the extension plate; and pinned to one end of a connector at each of the two base corners of the second connecting plate; the other end of each connector is pinned to a third... The third connecting plate is an isosceles triangular flat plate. The apex of the third connecting plate is pinned to one end of the connector. The two base corners of the third connecting plate are pinned to one end of a right-angled hanging plate. The other end of each right-angled hanging plate is connected to a tension clamp. Each tension clamp is connected to an inner ground wire. The two inner ground wires are distributed on both sides of the tower body. Each of the two inner ground wires is equipped with a second parallel groove clamp. The second parallel groove clamp is connected to one end of a second grounding wire. The other end of the second grounding wire is led into the ground through the tower body.

[0015] Furthermore, both the inner and outer ground wires are OPGW composite optical cable ground wires.

[0016] Compared with the prior art, the present invention has the following technical effects:

[0017] 1. The four-ground-wire lightning protection smart tower of the present invention can increase the height of the ground wire by setting up two extension arms and a dove-shaped ground wire bracket, thereby expanding the lightning protection area below the ground wire; by reasonably distributing the inner and outer ground wires, the four ground wires form an arc-shaped shielding surface, which can reduce the tower protection angle of the two outer ground wires, thereby obtaining better lightning protection performance. Furthermore, the two inner ground wires can compensate for the problem of reduced lightning protection performance in the middle after the outer ground wires are far apart, ensuring the overall lightning protection performance of the ground wire.

[0018] 2. The four-ground-wire lightning protection communication smart tower of the present invention, by setting the distance between the outer ground wires to be greater than the length of the third crossarm and the distance between the inner ground wires to be less than the length of the third crossarm, can make the tower protection angle formed between the outer ground wires and the conductor smaller, thereby obtaining better tower lightning protection performance.

[0019] 3. The four-ground-wire lightning protection smart pole tower of the present invention has a structural setting in which the angle between the plumb line of the outer ground wire and the line connecting the outer ground wire to the conductor on the adjacent first crossarm is 5°-10°. The resulting pole tower protection angle is -5°--10°. This angle setting satisfies the lightning protection performance of the ground wire while ensuring the structural strength of the entire power pole tower and avoids the stability of the overall power pole tower structure being affected by the excessive distance between the two dove-shaped ground wire supports.

[0020] 4. The four-ground-wire lightning protection communication smart pole of this invention facilitates data acquisition and storage by installing a data box on the third crossarm. Simultaneously, the data box communicates with the inner ground wire, enabling stable data transmission without the need for additional transmission lines. Furthermore, data transmission via the inner ground wire ensures stable communication even in areas without public wireless networks. By installing several first monitoring device groups on the conductors and several second monitoring device groups on the pole body, multi-directional monitoring of the pole and conductors can be achieved, comprehensively monitoring their operational status. The communication connection between the first and second monitoring device groups and the data box allows for real-time monitoring and data acquisition, enabling timely detection, diagnosis, and handling of pole and conductor faults, thus improving the reliability and stability of the pole and communication equipment.

[0021] 5. The four-ground-wire lightning protection communication smart pole described in this invention uses OPGW composite optical cable ground wires for both the inner and outer ground wires, which can greatly improve data transmission capacity. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0028] like Figure 1-2 As shown, a smart communication pole with four ground wire lightning protection includes: a pole body 1, on which a first crossarm 2, a second crossarm 3, and a third crossarm 4 are horizontally arranged from bottom to top. The first crossarm 2, the second crossarm 3, and the third crossarm 4 are symmetrically distributed around the pole body 1. Insulator strings 9 are provided at the lower ends of both ends of the first crossarm 2, the second crossarm 3, and the third crossarm 4. Conductors 10 are provided at the lower ends of the insulator strings 9. Two extension arms 5 are provided above the third crossarm 4, and the extension arms 5 face away from the ground. The tower body 1 is inclined upward and symmetrically distributed with the vertical line of the tower body 1 as the center line. The top of each extension arm 5 is provided with a dove-shaped ground wire bracket 6. The dove-shaped ground wire bracket 6 is provided with an inner ground wire hardware 15 on the side closer to the tower body 1, and an outer ground wire hardware 14 on the side away from the tower body 1. An inner ground wire 7 is provided on the inner ground wire hardware 15, and an outer ground wire 13 is provided on the outer ground wire hardware 14. The height of the inner ground wire 7 is higher than the height of the outer ground wire 13.

[0029] like Figure 1-2 As shown, the first crossarm 2, the second crossarm 3, and the third crossarm 4 have the same length. The distance between the outer ground wires 13 is greater than the length of the third crossarm 4, and the distance between the inner ground wires 7 is less than the length of the third crossarm 4.

[0030] like Figure 1-2As shown, the angle formed by the vertical line of the outer ground wire 13 and the line connecting the outer ground wire 13 to the conductor 10 on the adjacent first crossarm 2 is 5°-10°. The tower protection angle formed by the outer ground wire 13 and the conductor 10 on the adjacent first crossarm 2 is -5°--10°. This protection angle can improve the lightning protection performance of the transmission line, reduce the backflashover rate, and at the same time, it can also ensure the structural strength of the entire power pole tower, avoiding the instability of the overall structure due to excessive distance between the two dove-shaped ground wire supports.

[0031] like Figure 1-2 As shown, a data box 8 is installed on the upper part of the third crossarm 4. The data box 8 is communicatively connected to the inner ground wire 7. Several first monitoring device groups 11 are installed on each conductor 10, and several second monitoring device groups 12 are installed on the tower body 1. Both the first monitoring device groups 11 and the second monitoring device groups 12 are communicatively connected to the data box 8. Among multiple power towers, the outer ground wire 13 is a complete OPGW composite optical cable ground wire, while the inner ground wire is several segments of OPGW composite optical cable ground wire. The optical fiber inside each segment of the inner ground wire connects to the data boxes 8 on two adjacent power towers, thereby realizing data transmission between the data boxes 8 of different power towers.

[0032] like Figure 1-2 As shown, the first monitoring device group 11 further includes: a distributed fault monitoring device, a micro-wind vibration monitoring device, a conductor icing monitoring device, a conductor temperature monitoring device, a conductor sag monitoring device, a conductor wind deflection monitoring device, and a conductor galloping monitoring device.

[0033] like Figure 1-2 As shown, the second monitoring device group 12 further includes: a tower tilt monitoring device, a fitting temperature monitoring device, a micro-meteorological monitoring device, a wildfire monitoring device, a grounding power monitoring device, and a panoramic visualization monitoring device.

[0034] like Figure 3As shown, the outer ground wire hardware 14 further includes: a first trunnion mounting plate 141, the upper part of which cooperates with the dove-shaped ground wire bracket 6; a first U-shaped mounting plate 142 pin-connected to the lower part of the first trunnion mounting plate 141; a first connecting plate 143 pin-connected to the lower part of the first U-shaped mounting plate 142; the first connecting plate 143 is an isosceles triangular flat plate; the apex of the first connecting plate 143 is pin-connected to the lower part of the first U-shaped mounting plate 142; a first connecting plate 144 pin-connected to the two bottom corners of the first connecting plate 143; a suspension clamp 145 pin-connected to the lower part of the first connecting plate 144; an outer ground wire 13 disposed in the two suspension clamps 145; a first parallel groove clamp 146 disposed on the outer ground wire 13; one end of a first grounding wire 147 connected to the first parallel groove clamp 146; and the other end of the first grounding wire 147 introduced into the ground through the tower body 1. The outer ground wire is a complete OPGW composite optical cable ground wire. Therefore, in the entire power transmission line, the clamps that match the middle power poles and the outer ground wire mainly bear the vertical load. Therefore, the clamps that match the middle power poles and the outer ground wire can be suspension clamps 145.

[0035] like Figure 4 As shown, the inner grounding hardware 15 further includes: a second trunnion mounting plate 151, the upper part of which mates with the dove-shaped grounding bracket 6; a second U-shaped mounting plate 152 pinned to the lower part of the second trunnion mounting plate 151; an extension plate 158 pinned to the lower part of the second U-shaped mounting plate 152; a second connecting plate 153 pinned to the lower part of the extension plate 158; the second connecting plate 153 is an isosceles triangular flat plate; the apex of the second connecting plate 153 is pinned to the lower part of the extension plate 158; and one end of a connector 1510 pinned to each of the two base corners of the second connecting plate 153; the other end of each connector 1510 is pinned to a third... The connecting plate 154 is an isosceles triangular flat plate. The apex of the third connecting plate 154 is pin-connected to one end of the connector 1510. The two base corners of the third connecting plate 154 are pin-connected to one end of the right-angle hanging plate 155. The other end of the right-angle hanging plate 155 is connected to the tension clamp 156. The two tension clamps 156 are respectively matched with an inner ground wire 7. The two inner ground wires 7 are distributed on both sides of the tower body 1. The two inner ground wires 7 are each equipped with a second parallel groove clamp 159. The second parallel groove clamp 159 is connected to one end of the second ground wire 157. The other end of the second ground wire 157 is introduced into the ground through the tower body 1. Since the inner ground wire 7 between two adjacent power poles is an independent OPGW composite optical cable ground wire, the clamps that connect the middle power poles and the inner ground wires in the entire power transmission line need to withstand tension along the line direction in addition to the vertical load. Therefore, tension clamps 156 are used for the clamps that connect the middle power poles and the inner ground wires.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
