Accordingly, the development and research to protect the electronic communication equipment used in all industrial fields from lightning strikes are actively underway.

Lightning strike is a phenomenon in which a lightning path is formed when the electric field strength between the thundercloud and the earth rises over a certain level due to the development of the thundercloud, and a discharge source is formed between the thundercloud and the earth. There is damage.

For example, in the related art, a lightning rod is installed on an upper end of a fixed structure such as a building or a communication tower to prevent damage to direct lightning during the lightning strike.

More preferably, the second ion emitter 213 of the second disk array 210 is thinner than the first ion emitter 113 of the first disk array 110 so that the charge in the air is easily charged. It is short and has more numbers.

In addition, the second disk array 210 allows the third disk array 310 to perform a standby discharge function and simultaneously perform the point discharge function by interacting with the second disk array 210. It is desirable to have a smaller diameter than the three disk array 310.

In addition, the first ion radiator 113 extends upward and downward in the first frame 112, and the second ion radiator 213 is upward and downward in the second frame 212. It is preferable to extend in the direction.

In addition, the first disk array 110 and the second disk array 210 is preferably detachably fixed to the support rod 100 by screwing.]

Other objects and advantages of the present invention in addition to the above object will be apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, a lightning protection device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a lightning protection device according to the present invention, Figure 2 is a view showing the operating principle of preventing lightning through the present invention.

As shown in Figure 1, the lightning protection device according to an embodiment of the present invention, the ground and ground support rod 100, the first disk array 110 is installed on the support rod, the lower portion of the first disk array The second disk array 210 and the third disk array 310 are installed.

Specifically, the first disk array 110 is coupled to the support plate 100 by a screw coupled to the support plate 100, the coupling plate and the branch (branch) integrally coupled to a plurality of circular A first frame 112 configured, a first ion radiator 113 fixed to the first frame in a plurality of vertical directions, and collecting and dispersing charges, and connected to the coupling plate and connected to the support rod Connection cable 114, and is configured in an umbrella shape to maximize the effect of the space charge layer.

At this time, the first washer 115 and the first nut 116 are fastened to the support bar 100 by the lower portion of the coupling plate 111 of the first disk array 110, the upper portion of the coupling plate As the second washer 117 and the head cap 118 are fastened, the first disk array 110 is coupled to and detached from the support rod 100.

In addition, the first ion emitter 113 of the first disk array 110 should have electrical strength as a light receiving unit, and according to the diameter of the first disk array, the number, size and number of the first ion radiator The quantity is different.

On the other hand, the second disk array 210 is installed on the lower portion of the first disk array 110, the insulating plate 211 is coupled to the support rod 100, integrally through the branch and the insulating plate. The second frame 212 is coupled to a plurality of circular and a plurality of second ion emitter 213 is fixed to the second frame in the vertical direction up and down to perform the function of the charge capture and point discharge.

At this time, the third washer 215 and the second nut 216 are fastened to the lower portion of the insulating plate 211 of the second disk array 210, and the fourth washer is mounted on the upper portion of the insulating plate 211. 217 and the third nut 218 are fastened so that the second disk array 210 is coupled to and detached from the support rod 100 to be electrically insulated.

In addition, the second disk array 210 has a smaller diameter than the first disk array 110 and the third disk array 310, and thus the ion radiator of the first disk array and the third disk array. It is possible to simultaneously discharge its own space charge and point discharge with the second disk array (210).

In addition, the second ion radiator 213 of the second disk array 210 facilitates charge collection in the atmosphere and ion emitters 113 of the first and third disk arrays 110 and 310 installed at the upper and lower portions thereof. And a thinner, shorter, and much larger number of needle shapes than the ion emitters 113 and 313 so that point discharge between the and 313 is effectively performed.

On the other hand, as shown in Figure 1, the lower portion of the second disk array 210, the third disk array 310 may be additionally installed according to the purpose of the protection facility to improve the protection range and protection class.

At this time, the third disk array 310 is the same diameter and the same components as the first disk array 110, and has a flat plate structure compared to the first disk array that is only an umbrella shape and reference indicating each component Since only the sign is different, a detailed description thereof will be omitted.

In other words, like the first disk array 110, the third ion radiator 313 of the third disk array 310 performs a space charge discharge function on its own and simultaneously, 2 The counter leader for the downstream streamer from thunderclouds by performing the point discharge function with the ion radiator 213 to suppress the electric field strength by the charge transfer and to form the space charge layer by the corona.

In addition, if the second disk array 210 and the third disk array 310 are added to the lower part in the same order and according to the protection range and the degree of protection, the charge charge density induced on the ground and the ground structure by thunderclouds will be better. By keeping it low, the electric field strength (KV / m) between the thundercloud and the earth is kept very low, thereby making it impossible to form a discharge path between the thundercloud and the earth, thereby preventing lightning.

That is, the space charge layer formed by the space charge discharge and the point discharge between the multi-layer disk arrays is protected by suppressing the generation of the counter leader against the down leader caused by the thundercloud. It is not possible to terminate lightning strikes in the area.

On the other hand, the principle of operation of the lightning protection device of the present invention configured as described above will be described.

As shown in FIG. 2, when a thunderstorm develops in the air, the earth is generally charged with a charge (positive polarity) opposite to the lower end polarity (negative polarity) of the thundercloud. Electrostatic strength is generated between the grounds.

Then, in proportion to the electrostatic field strength, the first disk array 110 discharges charges (positive charges) induced in the ground into the air by the CTS (Charge Transfer System) principle to the space charge layer. Will be

On the other hand, between the radiator facing downward of the first ion emitter 113 of the first disk array 110 and the radiator facing upward of the second ion emitter 213 of the second disk array 210. Point discharge occurs and more active discharge occurs.

That is, an atmospheric discharge for distributing charge into the air through the first disk array 110, between the first disk array 110 and the second disk array 210, and between the second disk array 210 and the second disk array 210. Through the point discharge between the third disk array 310, the charge charge induced on the ground is actively distributed to the atmosphere.

In this case, the point discharge between the second disk array 210 and the third disk array 310 is directed toward the bottom of the second ion radiator 213 of the second disk array 210 and the third discharger. It occurs between the radiators facing upwards of the disk array 310.

Therefore, the strongly formed space charge layer suppresses the generation of a counter leader against a down leader generated by thunderclouds, thereby making it impossible to terminate lightning in the protected area.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.

That is, in one embodiment of the present invention, the lightning protection device is described as being installed in the fixed structure, but it can be applied to mobile facilities such as mobile communication vehicles, broadcasting station relay vehicles, special outdoor performance venues and military communication vehicles.
