The design of this device includes multiple key parts, among which the discharge sphere and the discharge rod are key components, responsible for guiding the current safely into the ground during a lightning strike, thereby protecting the line from damage. The main function of the lightning flashover protector is to detect abnormal changes in the current and quickly guide the overvoltage to the ground, thereby protecting the connected equipment from damage. The lightning flashover protector can quickly cut off the current under transient overvoltage conditions caused by lightning strikes or other electrical interferences, prevent it from being conducted to the equipment, can effectively absorb and dissipate the surge current in the power system, protect the safety of electronic equipment, and is usually connected to the grounding system to ensure that the overvoltage is effectively guided to the ground. In some complex power systems, multi-stage protection devices may be used to provide more comprehensive protection.

[0003] The installation of a lightning flashover protector usually requires the use of a mounting bracket to ensure that the protector is firmly and reliably fixed in the required position. Select a suitable bracket according to the type of the protector. Usually, screws or other fixing devices are needed to firmly fix the bracket on the wall or other supporting structures. However, it is inconvenient to adjust the installation position between the existing lightning flashover protector and the bracket, and it is not easy to install the protector according to different line lengths or other installation requirements, resulting in poor use effect of the mounting bracket. Moreover, the discharge rod and the discharge sphere of the existing lightning flashover protector are both in the open air, and when it rains, it is easy to cause damage to the lightning flashover protector and affect its use, which is rather inconvenient.

[0033] The present utility model will be further described in detail below in conjunction with embodiments:

[0034] Embodiment 1

[0035] As Figures 1-6 shown, the present utility model provides a lightning strike flashover protection device with an arc ignition electrode and multi-stage series gaps, including a flashover protector body 1, a connection component 4, and a first mounting bracket 6.

[0036] The connection component 4 is detachably connected to the flashover protector body 1; the connection component 4 includes a fixed plate 401, a "U"-shaped adjusting ring 402, and a fixed bolt 403; the "U"-shaped adjusting ring 402 is fixedly installed on the surface of the fixed plate 401, and two fixed bolts 403 are installed on the surface of the "U"-shaped adjusting ring 402; a sliding groove 601 for sliding connection with the "U"-shaped adjusting ring 402 is provided on the surface of the first mounting bracket 6, and positioning holes 602 matching a plurality of fixed bolts 403 are provided on the surface of the first mounting bracket 6.

[0037] In this embodiment, the top end of the flashover protector body 1 can penetrate through the surface of the connection component 4 and be fixedly installed by bolts. At this time, the connection component 4 can be connected to the flashover protector body 1. Since the "U"-shaped adjustment ring 402 is in a "U" shape, the operation of fixing the flashover protector body 1 on the fixing plate 401 is unobstructed. The "U"-shaped adjustment ring 402 is in a "U" shape, and both ends thereof can penetrate into two sliding grooves 601 on the surface of the first mounting bracket 6. When the flashover protector body 1 is fixedly connected to the connection component 4, the flashover protector body 1 is slid according to the installation position required. At this time, the "U"-shaped adjustment ring 402 slides on the first mounting bracket 6, and the installation position of the flashover protector body 1 can be adjusted according to the line length, which is more convenient and avoids the traditional bracket being fixed only by a plurality of bolts during use, and it is more laborious to adjust the position of the flashover protector body 1 during installation. A plurality of positioning holes 602 are opened on both sides of the surface of the first mounting bracket 6, and each positioning hole 602 conforms to the installation of each fixing bolt 403, so that after the position of the "U"-shaped adjustment ring 402 is adjusted, the fixing bolt 403 can correspond to the positioning hole 602 where it is located, thereby facilitating the use of the fixing bolt 403 to fix the installation position of the flashover protector body 1.

[0038] As Figures 1-6 shown, in this embodiment, preferably, it further includes two "U"-shaped connecting frames 7, which are respectively fixedly connected to both ends of the first mounting bracket 6; fixing holes 701 are respectively opened on the surfaces of the two "U"-shaped connecting frames 7. The two "U"-shaped connecting frames 7 are fixedly connected to both ends of the first mounting bracket 6 for use when installing at different position angles. The fixing holes 701 opened on the surfaces of the "U"-shaped connecting frames 7 are for facilitating the embedding of bolts for fixing, and the "U"-shaped connecting frames 7 being in a "U" shape is convenient for sliding positioning.

[0039] As Figures 1-6 shown, preferably, it further includes a second mounting bracket 8, which is detachably connected to the "U"-shaped connecting frame 7; a positioning chute 801 for sliding connection with the "U"-shaped connecting frame 7 is opened on the surface of the second mounting bracket 8. The second mounting bracket 8 is for connecting and using when the flashover protector body 1 is installed at a special position. During use, the second mounting bracket 8 can be clamped with the "U"-shaped connecting frame 7. At this time, both ends of the "U"-shaped connecting frame 7 can just be embedded into the inside of the two positioning chutes 801, which can play a positioning role, so that the installation position will not be offset when the "U"-shaped connecting frame 7 and the second mounting bracket 8 are installed, and it can better make each fixing hole 802 correspond to the fixing hole 701.

[0040] As Figures 1-6As shown, preferably, it further includes a protective cover 5, which is fixedly connected to the connection component 4. To ensure the effective operation of the components on the flashover protector body 1 and extend its service life, the protective cover 5 can be effectively used for protection to avoid being affected by the external environment, especially the influence of rain. If the rain directly contacts, it may affect its normal working state and even cause equipment damage.

[0041] As Figures 1-6 shown, preferably, the protective cover 5 is sleeved on the surface of the flashover protector body 1. One side of the protective cover 5 is connected through a wiring chamber 501, and a sealing ring 502 is arranged at the bottom of the protective cover 5. By setting the protective cover 5 and sleeving it on the flashover protector body 1, direct contact with rain can be avoided, thereby keeping it dry and clean and ensuring its normal operation when needed. In addition, the protective cover 5 can also provide additional protection to prevent damage caused by other external factors such as dust and pollutants, further enhancing the performance and reliability of the flashover protector body 1. The sealing ring 502 is sleeved on the other end of the flashover protector body 1 to prevent other dust and impurities from entering and affecting its use. The wiring chamber 501 communicates with the inside of the protective cover 5. After the protective cover 5 is sleeved on the flashover protector body 1, the wires on the flashover protector body 1 can be passed out through the wiring chamber 501 for connection and use. And the whole protective cover 5 is in a conical umbrella shape, so that rainwater can slide down from the surface of the protective cover 5 to the bottom end in rainy weather, avoiding rainwater accumulation on the surface of the protective cover 5, and making the protective effect of the protective cover 5 on rainwater better.

[0042] As Figures 1-6 shown, preferably, a plurality of fixing holes two 802 are formed on the surface of the mounting bracket two 8, and each fixing hole two 802 corresponds to the fixing hole one 701. When assembling and splicing between the "U" - shaped connecting frame 7 and the mounting bracket two 8, the two ends of the "U" - shaped connecting frame 7 can be movably embedded in the positioning chute 801 formed on the surface of the mounting bracket two 8, so as to preliminarily position the installation between the "U" - shaped connecting frame 7 and the mounting bracket two 8. Adjust the position of the mounting bracket two 8 according to the installation requirements, so that the mounting bracket two 8 will not shift from the corresponding position of the "U" - shaped connecting frame 7 during the adjustment process. After the fixing hole two 802 corresponds to the fixing hole one 701, use two bolts to fix them, so that the flashover protector body 1 can be installed and used. Splicing the "U" - shaped connecting frame 7 and the mounting bracket two 8 can expand the use range of the bracket, and can install the flashover protector body 1 at different positions and angles, making the use effect of the bracket better and convenient for disassembly.

[0043] As Figures 1-6As shown, preferably, it further includes a discharge rod 2 and a discharge ball 3. Two discharge rods 2 are provided on one side of the flashover protector body 1, and a discharge ball 3 is provided on one side of each discharge rod 2. The discharge rod 2 and the discharge ball 3 are key components for guiding and dispersing lightning current. During a lightning strike, the discharge rod 2 and the discharge ball 3 can provide a low-impedance path to safely guide the lightning current to the ground, reducing damage to equipment and buildings. The design of the discharge rod 2 and the discharge ball 3 can promote the ionization of the gas in the surrounding air to form a conductive channel, enhancing the discharge ability, so that the lightning current can be released more effectively. By effectively guiding the lightning current, the discharge rod 2 and the discharge ball 3 can protect electronic equipment and buildings from voltage spikes and electromagnetic interference caused by lightning strikes.

[0044] Next, the working principle of the multi-stage series gap lightning flashover protection device with an arc ignition electrode will be specifically described.

[0045] As Figures 1-6 shown, during use, first insert one end of the flashover protector body 1 into the inside of the embedded protective cover 5, so that one end of the flashover protector body 1 passes through the connecting component 4, and then fix the flashover protector body 1 with a nut. The position of the flashover protector body 1 can be moved according to the installation length of the flashover protector body 1 circuit or other installation requirements, so that the connecting component 4 can slide on the first mounting bracket 6 for position adjustment. After adjusting to a reasonable position, fix the connecting component 4 on the first mounting bracket 6 through two "U"-shaped adjusting rings 402. At this time, the installation position of the flashover protector body 1 can be fixed, and it is judged whether it is necessary to connect the second mounting bracket 8 according to the installation of the flashover protector body 1 for special position installation, so that the "U"-shaped connecting frame 7 is spliced with the second mounting bracket 8 for use. At this time, both ends of the "U"-shaped connecting frame 7 can be movably embedded in two positioning chutes 801 and can slide. After adjustment, use two bolts to fixedly connect the "U"-shaped connecting frame 7 and the second mounting bracket 8, which is convenient for operation. Since the protective cover 5 is connected to the connecting component 4, the protective cover 5 can be sleeved on the surface of the flashover protector body 1 to protect the discharge rod 2 and the discharge ball 3. The protective cover 5 can effectively protect the discharge rod 2 and the discharge ball 3 from the influence of the external environment, especially the influence of rainwater, preventing rainwater from contacting the discharge rod 2 and the discharge ball 3 and affecting their normal working state, and avoiding equipment damage, further enhancing the performance and reliability of the flashover protector body 1. After connecting the flashover protector body 1 and the connecting component 4, the position of the flashover protector body 1 can be slid for adjustment, making the installation of the flashover protector body 1 more flexible, reducing the installation difficulty of the staff, being more convenient to operate, and being able to use different brackets in combination when installing the flashover protector body 1 at different positions, with better use effects.

[0046] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
