Description

Technical Field

[0001] The invention relates to a ground potential installation system for a lightning protection device and an installation method thereof. Background Art

[0002] Currently, 10kV overhead lines generally employ a combination of channeling and blocking lightning protection methods. This involves installing an overvoltage protector in parallel with the original lightning protection insulator or support insulator. This protector limits overvoltage and interrupts power-frequency continuous current, resulting in improved lightning protection. However, these parallel-installed overvoltage protectors almost always require a power outage for maintenance or live installation using an insulated boom truck. If the overhead line passes through narrow old town streets, farmland orchards, or highway greenery, where an insulated boom truck cannot enter for live installation, installation is necessary during a power outage.

[0003] As the requirements for power supply reliability of power lines continue to increase, power grid companies are vigorously developing live working technology. Some key and important lines have repeatedly experienced tripping accidents, but they are unable to carry out long-term power outages for maintenance or due to environmental conditions that do not allow insulated boom trucks to intervene to install lightning protection measures. Ground potential installation is an important method for live installation of distribution lines. Especially in recent years, the State Grid Corporation has placed high demands on line power supply reliability, and the scope of live working has become increasingly broad. There are already a large number of plug-type lightning protection devices of various structural types in China, including those with pure air gaps and those with fixed gaps, but no application technology for lightning protection devices that can be installed at ground potential has been proposed.

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the specific implementation methods thereof are described in detail below with reference to the accompanying drawings:

[0046] See also Figures 1 to 13 In an embodiment of the present invention, a ground potential installation system for a lightning protection device includes a lightning protection device A, a high-voltage drainage clamp B, and a live installation tool C.

[0047] See also Figure 2 The lightning protection device A includes a high-voltage soft lead 301, a supporting insulator 302, a high-voltage discharge ball 303, a lower drainage ball 304, a lightning arrester body 305, a lightning protection base 306 and a clamp 307. The lower end of the supporting insulator 302 and the lower end of the lightning arrester body 305 are respectively connected to one side of the lightning protection base 306, and a V-shaped angle is formed between the supporting insulator 302 and the lightning arrester body 305; the other side of the lightning protection base 306 is connected to the clamp 307. The high-voltage discharge ball 303 is arranged at the upper end of the support insulator 302 and is located on the inner side of the V-shaped angle; the lower drainage ball 304 is arranged at the lower end of the arrester body 305 and is located on the inner side of the V-shaped angle; an air gap is formed between the high-voltage discharge ball 303 and the lower drainage ball 304, and the air gap is located on the inner side of the V-shaped angle formed between the support insulator and the arrester body; one end of the high-voltage soft lead 301 is connected to the upper end of the support insulator 302.

[0048] Lightning arrester device A differs from other lightning-break overvoltage protectors used on 10kV insulated overhead lines. It features a systematically redesigned structure. The entire device features a V-shaped, integrated structure. Beyond the high-voltage flexible lead terminals, the grounded arrester base 306, and the clamp 307, there are no exposed metal parts. No additional insulating cover is required, resulting in a higher level of insulation and a more positive ecological coexistence with birds and other animals on the line. Although the high-voltage discharge ball is supported by a support insulator, it is a pure air-series-gap metal oxide arrester. The sheath of the insulator support 302 fully ensures the insulation level of the insulator itself, ensuring the stability of the pure air-gap discharge over long-term use and superior pollution resistance. Because the support insulator 302 and arrester body 305 are not connected in series but are instead split into two sections, both fixed to the arrester base 306, the device's dimensions are shortened, significantly improving the device's mechanical performance and flexibility in installation space. The arrester body 305 can greatly improve its flow capacity and pollution resistance on the basis of meeting the mechanical properties.

[0053] The fixing screw 5 is screwed into the fixing screw threaded hole 19 of the clamping base 1. The fixing screw 5 is used to insert and lock the high-voltage soft lead. The high-voltage soft lead is screwed into the lead threaded hole 14 of the clamping base 1. After tightening, the end of the high-voltage soft lead is tightened and fixed by the fixing screw 5 in the fixing screw threaded hole 19.

[0054] The high-voltage drainage clamp B can be equipped with a puncture needle 6 as needed. Two puncture needle mounting holes 13 are provided on the inner wall of the wire clamping groove 15 of the wire clamping base 1.

[0057] The ratchet socket wrench 10 includes an insulating handle 102, a ratchet socket head 101 and a wrench operating ring 103. The insulating handle 102 is hollow cylindrical. One end of the insulating handle 102 is connected to the ratchet socket head 101 through an elastic cylindrical pin 104, and the other end of the insulating handle 102 is connected to the wrench operating ring 103 through an elastic cylindrical pin 104.

[0058] The wrench operating rod 20 includes an operating base 203, an insulating operating rod 204, a U-shaped bracket 202 and a wrench cylindrical pin 201. The operating base 203 is fixed to the top of the insulating operating rod 204, the bottom end of the U-shaped bracket 202 is fixed to the top of the operating base 203, and the two ends of the wrench cylindrical pin 201 are connected to the two ends of the U-shaped bracket 202 one by one.

[0059] The wire clamp support rod 9 and the wrench operating rod 20 are arranged opposite each other and are connected by the ratchet socket wrench 10.

By pulling the insulating operating rod 204 up and down, the ratchet socket head 101 can be driven to rotate.

[0060] In actual use, the live installation tool C is an integrated type and cannot be temporarily disassembled. The insulating support rod 95 and the insulating operating rod 204 respectively adopt a telescopic rod with adjustable length or a multi-section rod that can be spliced ​​in multiple sections, and the length can be adjusted according to actual use.

[0061] See also Figure 11 、 Figure 12 and Figure 13When using the lightning protection device A, the high-voltage drainage clamp B and the live installation tool C, first screw the high-voltage soft lead 301 of the lightning protection device A into the lead threaded hole 14 of the clamp base 1 through the thread, and then tighten it with the fixing screw 5 in the fixing screw threaded hole 19; then, the installation tool connecting blocks 11 on the front and rear sides of the clamp base 1 of the high-voltage drainage clamp B are plugged into the front F-type plate and the rear F-type plate of the F-type clamp connecting block 91 one by one, and the hexagonal head of the tightening shaft 3 of the high-voltage drainage clamp 1 passes through the right U-shaped plate of the F-type clamp connecting block 91 and is inserted into the ratchet socket head 101. After the dedicated live installation tool is inserted through the above cooperation, the high-voltage drainage clamp is slowly hung into the overhead wire through the wire clamping groove 15 with the insulating support rod 95. After it is hung securely, the ratchet socket head 101 is driven to rotate the tightening shaft 3 by pulling the insulating operating rod 204 up and down. As the tightening shaft 3 rotates, the clamping block 9 tightens accordingly, ultimately securing the overhead wire within the wire clamping groove 15 of the clamping base 1 and the wire pressing groove 74 of the clamping block 7. The puncture needle 6 then penetrates the insulation layer of the insulated wire. When the insulating operating lever 204 becomes incapable of being pulled up or down, the high-voltage drain wire clamp is securely in place, and the live installation tool can be withdrawn horizontally.

[0069] S7. After confirming that the high-voltage drainage wire clamp B is tightened into place, first move the wire clamp support rod 9 of the live installation tool C horizontally, remove the high-voltage drainage wire clamp B from the F-type wire clamp connecting block 91 of the wire clamp support rod 9 of the live installation tool C, and then slowly lower the live installation tool C vertically to complete the live construction of connecting the ground potential on the pole to the lightning protection device.

[0071] The lightning protection device is installed horizontally, with the air gap inside the V-shaped angle. The discharge balls are all hidden inside, preventing birds from flying or moving through the gap and making it difficult for them to get caught on high-altitude objects, thereby improving the lightning protection device's ability to withstand external damage. On-site installation is very simple and convenient.

[0072] The lightning protection device ground potential installation system and its installation method of the present invention can complement the live installation technology of lightning protection measures in areas where insulated boom trucks cannot access live installation operations. This completely resolves the limitations of on-site installation conditions for lightning protection devices and meets the needs for upgrading lightning protection measures for both new and existing power lines. This provides a new technical means for installing lightning protection measures without power outages, greatly expanding the scope of line implementation for lightning protection device installation without power outages, and is of great significance for improving power supply reliability.

[0073] In summary, the ground potential installation system and installation method of the lightning protection device of the present invention can realize live installation operations directly on the pole, simplify the operating personnel and working tools, improve work efficiency, and reduce equipment use costs. In particular, many areas where the original insulated bucket trucks could not intervene in live installation operations can now realize ground potential live installation, expanding the scope of non-stop power operations.
