Description

Hybrid lightning protection device {HYBRID TYPE LIGHTNING PROTECTION APPARATUS}

The present invention relates to a hybrid lightning protection device, and more particularly, to apply a charge transfer system through the first and second ionizers having different discharge characteristics along with a function of inducing lightning through a lightning rod. The present invention relates to a hybrid lightning protection device that simultaneously performs a function of preventing lightning.

In recent years, as global warming progresses rapidly, the number of lightning strikes is frequently generated and the intensity of lightning strikes is increasing day by day, resulting in a sharp increase in damage to human life and communication facilities.

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

Conventionally, a lightning rod safely induces an impact current caused by a direct lightning strike to the ground to prevent damage such as a human accident and a damage to a communication facility caused by a lightning strike. It is occurring.

That is, when a direct lightning strike is induced by a conventional lightning rod, an induced lightning strike is generated by an essentially accompanying phenomenon, and the induction of the direct lightning strike causes an adverse effect on damage such as damage of an electronic communication facility installed indoors. do.

As shown in Figure 2, the hybrid lightning protection device according to an embodiment of the present invention is a lightning rod 110, the first ionizer 120, the second ionizer 130, the sleeve 140, the CAD weld ( 150, a support rod 160, a ground lead 170, and a CAD lead 180 for the ground lead.

At this time, the lightning arrester 110, the first ionizer 120 and the second ionizer 130 is composed of a single unit and electrically connected without the connection by the bolt and nut.

Specifically, the lightning rod 110 is made of stainless steel or copper rod with a cross-sectional area of 50mm ² or more, the upper end is formed in a conical shape to induce lightning when the thundercloud of the lightning protection performance is developed.

As shown in FIG. 3, the first ionizer 120 is formed in a cylindrical spiral brush state to be fitted to the lightning rod 110, and both ends thereof are fixed by welding to the lightning rod 110 to prevent impact of the lightning current. It is configured not to cause mechanical deformation.

In detail, the first ionizer 120 may include a plurality of stainless wires having a diameter of 0.1 mm to 0.3 mm between the first flat conductor 121 and the second flat conductor 122. 123 are arranged in a line at intervals of 1 mm to 5 mm, and the first flat plate conductor 121 and the second flat plate conductor 122 are folded in half, and then fixed to each other, thereby forming approximately 1000 to 3000 points. 110) maximizes ion discharge characteristics and at the same time disperses the earth's charge charge to the atmosphere at low constant voltage intensity.

Here, the Applicant has confirmed through experiments that the ion dissipation current value increases under the same conditions as the diameter of the wire 123 of the first ionizer 120 is thinner than 0.3 mm, as shown in FIG. 5.

The first ionizer 120 configured as described above is capable of repeatedly maintaining the lightning induction function and the lightning protection function by the lightning rod 110 wound around the center of the lightning ion induction center dedicated to the main circuit function of the brain current.

That is, the first ionizer 120 causes the lightning current to be discharged by the lightning rod 110 during lightning induction, and the first and second flat conductors do not twist and fix the wire 123 that performs the ionizer function. By folding and fixing the 121 and 122, the electrical burden is reduced.

On the other hand, the second ionizer 130 is disposed in the lower portion of the first ionizer 120 in a radiation type, one end is fixed to the lightning rod 110 by the sleeve 140 and the other end is the first ionizer The wires 123 of 110 are disposed at the same height so as to disperse the charged charge on the earth as high as possible at high constant voltage strength.

That is, as shown in FIG. 6, the second ionizer 130 has a bundle shape while being approximately the same height as the lightning rod 110 on the outside of the first ionizer 120 before being unfolded in the form of radiation. After fixed installation through the sleeve, it is unfolded in the form of a circular radiation.

At this time, by disposing the first ionizer 120 and the second ionizer 130 having different discharge characteristics at the same height in a radiation type, as shown in FIG. 7, the ion dissipation current is reduced from the low constant voltage intensity to the high constant voltage intensity. The formation of a space corona layer that increases and suppresses the counter reader is further strengthened to prevent lightning.

Here, the applicant has confirmed that the ion dissipation current value increases as the cutting angle of the tip of the second ionizer 130 is about 30 ° to 45 ° as shown in FIG. 9, as shown in FIG. 10. As the mutual spacing between the points of the second ionizer 130 is about 100 mm to 300 mm, the ion dissipation current value increases, and when the applied voltage is greater than a predetermined value at intervals of less than 100 mm, the insulation between the ends is broken and the points are mutually separated. The corona phenomenon occurred in the liver, and when the applied voltage is increased in stages, the discharge charge reaches the saturation point, and finally, it was confirmed through the experiment that the dissipation characteristic is the same as one point.

Meanwhile, after fixing the second ionizer 120, the sleeve 140 is welded to satisfy mechanical and electrical characteristics and then connected to the support rod 160 through the CAD weld 150.
