It should be noted that the fixed connection may be welding, or may be other fixed connection manners, and is not limited specifically herein.
The following theoretical analysis is combined to verify that the lightning protection device provided by the embodiment of the invention can reduce damage to other equipment accessing the metal grounding grid while lightning protection is realized, and the specific analysis is as follows:
the existing lightning rod cannot prevent lightning is that a large amount of charges in thundercloud enter the ground from a lightning channel, so the lightning rod must be grounded; pictures of lightning taken with a high-speed camera show that the lightning time is only 70 mus, since thunderclouds are media in which there are not a large number of free electrons, and only on the order of 10 in such a short time by calculation of the charge measurement data in the thunderclouds-8Coulomb charges go to ground, so it can be considered that no charges go to ground. The causes of lightning are: the ice crystals in the thundercloud collide with each other to be charged, the charged clustered ice crystals form a distortion electric field to break down air, according to the high-voltage streamer theory, the broken down air forms a pilot plasma and a space positive charge cluster, and a ground induction object forms a charged body with separated positive and negative charges under the charge induction of the space positive charge cluster; as the positive and negative charges are attracted, when an electric field formed by the space positive charge groups breaks down an air gap between the electric field and an electric field formed by the ground induction object, lightning is formed; after lightning disappears, the space positive charge groups and electrons in breakdown air are neutralized and disappear, positive and negative ions in the induction object are also neutralized, and relaxation current can be generated when the charged state is restored to the uncharged state; the lightning current measured by various devices is actually relaxation current when the metal lightning receptor 101, the grounding wire 102 and the ground grid 103 are restored to an uncharged state from a charged state; at the same time, the relaxation current produces a ground potential rise in the distribution parameters on the earth screen 103, which is applied to the device via the earth line of the device connected to the earth screen 103, breaking the insulation between the earth line and the power supply line of the device, and the device is damaged.
According to the generation and development process of the direct lightning, the direct lightning can be divided into four stages of initial breakdown, pilot ionization, re-breakdown, end disappearance and the like, in the initial breakdown and pilot ionization processes, according to the flow stream theory of high-voltage large-gap breakdown, a pilot plasma column and a flow stream high-density space positive charge group are formed after the large-gap air breakdown, a lightning receptor or other inductive objects are arranged below the pilot plasma column and the flow stream high-density space positive charge group, opposite charges are induced on the ground lightning receptor by the space positive charge group of the pilot head flow stream, referring to fig. 1, in the prior art, the lightning receptor 101 is connected with the metal grounding grid 103 through a grounding down conductor 102, but after the direct lightning, the lightning receptor 101 and the metal grounding grid 103 both generate relaxation currents which are recovered from a charged state to an uncharged state, and the high-rise test shows that the larger the metal structure of the metal grounding grid 103 generates relaxation currents, as measured in a 60-meter overhead tv tower in south africa, a relaxation current of 44KA, which produces a huge ground potential rise on the metal counterpoise 103, which is applied via the metal counterpoise 103 to other grounded devices or buildings connected to the metal counterpoise 103, in particular to base station devices in the field of communications, causing damage to these devices.
Through the above analysis, it is a key factor for lightning protection of base stations to prevent ground potential rise caused by relaxation current, if no or small, so that the ground potential rise caused by the relaxation current is within the endurance of the grounding devices, and thus the ground potential rise does not damage the grounding devices. As can be seen from the above analysis, it is inevitable that the lightning receptor attracts the lightning, so that it is difficult to avoid generating the relaxation current, and therefore, only the relaxation current can be reduced, so as to reduce the generated ground potential rise as much as possible, thereby playing a role of lightning protection and reducing damage of the ground potential rise to other grounding devices.
From the Gaussian theorem, it can be known that: the flux of the electric field through any closed surface in vacuum is equal to the algebraic sum of the charges enclosed by the closed surface divided by epsilon0. Due to the epsilon of air01, can obtain:
wherein,for said electric field intensity flux, qiThe electric charge enclosed by the closed curved surface.
Fig. 3 is a schematic diagram of induced charges between the lightning receptor and the protected object, as shown in fig. 3, after the lightning receptor 301 is induced by the space charges of lightning to generate induced charges Q, the induced charges Q can be used as induced charges to also induce charges Q on the protected object 302 (such as a building or a base station iron tower, etc.), since the area of the lower portion of the lightning receptor 301 is relatively small, the induced charges Q are regarded as point charges, and the electric field generated at a position with a distance r from the lower portion of the lightning receptor 301 is:
where Q is the induced charge in the lightning receptor 301 (i.e. the induced charge of the protected object) and E is the electric field generated by the induced charge in the lightning receptor 301 at a distance r therefrom. Taking the top of the protected object 302 as a gaussian surface, assuming that the area of the top of the protected object 302 is S, and meanwhile, according to the equations (1) and (2), we can obtain:
where Q is the induced charge in the lightning receptor 301 (i.e. the induced charge for the protected object 302), S is the area of the top of the protected object 302, r is the distance between the protected object 302 and the induced charge of the lightning receptor 301, and Q is the induced charge in the protected object 302. If the diameter of the top of the protected object 302 is 0.4 m, S is 0.125m2. Fig. 4 is a schematic structural diagram of a lightning arrester and a protected object according to an embodiment of the present invention, as shown in fig. 4, wherein a base of the lightning arrester is not shown in the drawing, a length L of the insulator 402 is a distance between the lightning receptor 401 and the protected object 403, that is, r in the above formula (3), and Q/Q values corresponding to insulators with different lengths can be obtained, as shown in table 1:
TABLE 1
It can be seen that, when the distance between the lightning receptor 401 and the protected object 403 is 2 meters, the amount of charge induced by the protected object 403 is only five thousandths of the amount of charge induced by the lightning receptor 401. Since the current and the charge are in a proportional relationship, the voltage across the object 403 to be protected is caused by charge redistribution, and as can be seen from the fact that the current i is q/t, the charge decreases in the same time, the current decreases, and it can be seen from ohm's law that the voltage difference generated across the object 403 to be protected naturally decreases. According to tests, the relaxation current generated by a single lightning arrester is 30KA-44KA, 0.5% of the relaxation current is 150A-220A, the relaxation current is reduced by two orders of magnitude, the relaxation current of the protected object 403 is greatly reduced, the ground potential of the protected object 403 connected with the metal grounding grid on the metal grounding grid is reduced due to the reduction of the current, and when the ground potential is reduced to a range which can be borne by other equipment connected with the metal grounding grid, the other equipment cannot be damaged.
According to the lightning arrester provided by the embodiment of the invention, the insulator is fixedly connected below the lightning receptor, so that the damage of induced charges generated after the lightning receptor receives lightning to an object to be protected is isolated, the damage of ground potential rise generated by the fact that the lower lead is connected to a metal grounding grid to other equipment connected to the grounding grid is reduced, the lightning protection effect is enhanced, and the lightning protection cost is reduced.

The lightning receptor 501 induces a negative charge near the end of the lightning conductor after receiving the lightning, and generates a positive charge at the end connected to the insulator, and the positive charge generates a negative charge (induced charge) as an induced charge at the end of the metal rod 503 connected to the insulator 502 (the end near the lightning receptor 501), that is, the relaxation current is generated in the metal rod 503, and the relaxation current is much smaller than the relaxation current of the lightning receptor 501, and the other end of the metal rod 503 is connected to the base 504, and further, the induced current on the protected object 505 is much smaller than the relaxation current of the lightning receptor 501, so as to further ensure that the protected object is not damaged by the lightning conductor, and simultaneously reduce the relaxation current on the metal ground mesh, thereby reducing the damage to other grounding devices.
