AI Technical Summary
When the electric field strength of a thundercloud reaches a certain level, existing lightning protection devices may fail to establish a conductive path due to the lag or advance of the upward leader compared to the downward leader, resulting in lightning striking the protected object.
A solid insulating rod and a self-dissipating component are installed between the lightning arrester and the lower support. The charge is merged and returned to zero in the self-dissipating component to avoid the generation of an upward leader. A charge zeroing point is formed by setting a metal coil and a conductive rod to prevent lightning detection devices.
It effectively prevents lightning from striking the protected object, protecting the equipment from lightning strikes and overvoltage damage, and achieving safe lightning guidance and zeroing effect.

[0035] That is, the first conductive rod 410, the second conductive rod 420 and the third conductive rod 430 are located in the same plane, the first conductive rod 410, the second conductive rod 420 and the third conductive rod 430 are in conductive connection with the metal coil 210, the position where the third conductive rod 430 is connected with the metal coil 210 is the midpoint between the two ends of the metal coil 210, and the number of turns and direction of the metal coil 210 between the third conductive rod 430 and the first conductive rod 410 are the same as the number of turns and direction of the metal coil 210 between the second conductive rod 420 and the third conductive rod 430.

[0038] In some embodiments, the distance between the first ball head 411 and the third ball head 431 and the distance between the second ball head 421 and the third ball head 431 are both 5cm-10cm.
[0039] In some embodiments, the diameters of the first ball head 411, the second ball head 421 and the third ball head 431 are equal, and the diameter is 1cm-2cm.
[0040] In some embodiments, the lightning receptor 100, the metal coil 210, the first conductive rod 410, the second conductive rod 420, the third conductive rod 430, the first ball head 411, the second ball head 421, the third ball head 431 and the lower support 300 are all made of metal.

[0043] In some embodiments, the diameter of the umbrella skirt 230 includes a large diameter and a small diameter, and the umbrella skirt 230 is arranged equidistantly along the insulating rod 200 between the large diameter and the small diameter. The equidistant arrangement of the large diameter and the small diameter is to make the electric field distribution more uniform, and the values of the large diameter and the small diameter need to be determined according to the voltage borne by the umbrella skirt 230.
[0044] In some embodiments, the number of turns of the metal coil 210 is 32-60 turns.
[0045] That is, the number of turns between the first conductive rod 410 and the third conductive rod 430 is 16-30 turns, and the number of turns between the second conductive rod 420 and the third conductive rod 430 is also 16-30 turns, and the number of turns between the first conductive rod 410 and the third conductive rod 430 is equal to the number of turns between the second conductive rod 420 and the third conductive rod 430.

[0047] It should be noted that the base 500 needs to be conductively connected in the use position to ensure that the electric charge can reach the lower support 300 through the base 500.
[0048] Figure 5 It is shown that in another embodiment, it further includes a lightning monitoring device 310 arranged on the lower support 300, for monitoring whether there is lightning strike, the number of lightning strikes and the amplitude of lightning current.
[0049] When the thunder cloud passes, the leading discharge charge will flow from the ground to the self-energy consumption lightning protection device, the self-energy consumption component 400 will drive the voltage U of the leading discharge charge, taking the third ball head 431 as zero point, +U / 2 and -U / 2 on the first ball head 411 and the second ball head 421 respectively, +U / 2 and -U / 2 will be combined to zero at the third ball head 431, thus, the leading discharge to the sky will not be generated, the thunder cloud will not identify the device protected by the device, and the real lightning protection effect is achieved. Similarly, when the lightning or other overvoltage caused by other factors passes through the device protected by the device, the self-energy consumption component 400 of the device will divide the lightning voltage or other overvoltage U into +U / 2 and -U / 2 at the third ball head 431, and finally the positive and negative voltages will be combined at the third ball head 431, the voltage driving the charge movement will be zero, and finally the lightning or overvoltage damage will not be generated.
[0050] In some embodiments, the effective protection range of the self-energy consumption lightning protection device is 1-2 lightning wavelengths.
[0051] Figure 6 The detection laboratory layout photo of one embodiment of the present application is shown, in which the lightning impulse voltage test is carried out, and the lightning impulse voltage is 1.2 / 50 μs (1.2 / 50 μs refers to a smooth lightning impulse full wave with a wave front time T1 of 1.2 μs and a half-wave peak time T2 of 50 μs); Figure 7 The lightning striking moment photo of one embodiment of the present application is shown, in which Figure 7 As shown, at the lightning striking moment, strong electric sparks appear between the lightning rod tip and the upper end experimental plate, and the first ball head 411, the second ball head 421 and the third ball head 431 are not broken down.

[0053] Figure 9 The voltage collection waveform graph of the third ball head 431 to the ground in one embodiment of the present application is shown, in which Figure 9 As shown, the third ball head 431 can form a waveform with a positive and negative amplitude close to each other at the lightning striking moment, which proves that the +U / 2 and -U / 2 voltages are formed on both sides of the third ball head 431, and at the same time, the +U / 2 and -U / 2 voltages are also formed between the first ball head 411 and the third ball head 431 and between the second ball head 421 and the third ball head 431; Figure 10 The voltage collection waveform graph of the first ball head 411 to the ground in one embodiment of the present application is shown, in which Figure 10As shown, the starting point of the waveform is negative voltage, and the first ball head 411 is closer to the lightning receptor, so it can be explained that the lightning protection device will not generate an uplink guide to the thundercloud.
