BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a virtual multi-point grounding multi-tubular surge discharge ground rod that enables the rapid discharge of huge charges induced by lightning rods and down-conductors into the ground. In particular, a plurality of conductive regions are provided horizontally and radially around the outside of the ground rod. The present invention relates to a virtual multi-point grounding multi-tubular surge discharge ground rod that is formed to create a virtual multi-point grounding effect.

In general, it is recognized that it is desirable to install underground depth as much as possible to lower the ground resistance. However, as the geology of Korea is a paleozoic earth, the lower the lower the lower the frequency, the higher the frequency of rocks and the lower the resistance of ground resistance. There is a problem.

Therefore, the inventors of the present application, as part of an attempt to reduce the ground resistance in the horizontal direction in the state buried at a depth of about 1.5m or more without excessively installed deep underground, Republic of Korea Patent Publication No. 10447447 (name of the invention: Tubular surge discharge ground rod (hereinafter referred to as 'quoting invention') has been proposed, which is a "center tube 200, a first copper tube 300, and a second copper tube 400 formed with an outlet hole 801 on the circumferential surface thereof. Put the reducing agent 800 in the buried, but inside the first and second copper tubes 300, 400 having a diameter larger than the center tube 200 so that the second copper tube 400 of the largest diameter is disposed at the outermost ,

And a plurality of first and second copper tubes 300 and 400 overlapping and fixed by fixing the upper and lower covers 500 and 501 to the upper and lower portions of the second copper tube 400, and "and" a " The embedding of the reducing agent in the second copper tube 400 is formed in the circumferential hole 801, the second copper tube larger in diameter than the center tube 200, one or more central tube 200 is small Put inside the 400 to be placed in the outermost second copper tube 400 of the largest diameter,

The upper and lower covers 500 and 501 are fixed to the upper and lower ends of the second copper tube 400 so that a plurality of copper tubes overlap and are fixed, and a plurality of spaces are formed between the center tube 200 and the second copper tube 400.

According to this cited invention, a huge amount of charges entered through a lightning rod in a very short time is to be directly ground-discharged or ground-discharged through a reducing agent due to the skin effect of a very large surface of a multi-tubular surge discharge ground rod. As a result, it is possible to safely and effectively discharge the electric charge that reaches the ground rod without flowing backward through the lightning rod, and thus it is expected to have an excellent effect of greatly improving the performance of the ground rod.

In addition, as shown in FIG. 1, by repeatedly forming protrusions on the surfaces of the plurality of copper tubes, the surface area can be greatly increased, and the vast amount of charges reached in a very short time can be immediately discharged to the ground by a very large surface. Since the ground rod underground discharge performance is greatly improved.

As can be seen from the above, the cited invention is able to rapidly discharge a huge charge by increasing a large surface area, and although it is possible to accommodate a large amount of reducing agent to maintain a continuous reduction of ground resistance, the construction area According to the soil quality, there was a case in which contact resistance increased due to insufficient soil contact with the soil.

That is, as shown in Figure 3, the cited invention is the degree to which the reducing agent is dispersed around the discharge hole 801 of the circumferential surface of the second copper tube 400 disposed in the outermost, so that the soil and glass is not sufficiently absorbed in the surrounding soil There is a problem that does not sufficiently lower the ground resistance.

It is ejected to the outside through the discharge hole 901 of the formed stone pipe (900).

As described above, the reducing agent discharged to the discharge hole 901 is discharged around the tip of the stone pipe 900 and absorbed into the soil around the stone pipe 900, so that the stone pipe 900 and the soil are electrically integrated with each other. An area is formed, and this state is shown in FIG. 8.

As can be seen from this, in the present invention, the conductive area is formed by the number of the protrusions 900, so that the grounding rod according to the present invention has a plurality of contact resistances with the earth due to the outermost third copper tube circumferential area and a plurality of The number of conductive regions 902 by the two protrusions 900 is in a state in which contact resistances with the earth are connected in parallel by contact with the soil, and an equivalent circuit diagram of such a state is shown in FIG. 9.
