Description

An Air Terminal of Space Charge Dissipation Type

The present invention relates to a space charge distributed lightning arrester, and more particularly, to a space charge distributed lightning arrester installed on a rooftop of a building to prevent electric shocks caused by lightning strikes by preliminarily discharging ground charges due to thunderstorm proximity. will be.

As is well known, a lightning arrester is a device for safely inducing (discharging) an impact current caused by a lightning strike to the ground to prevent fire, damage, and injury to a building. Installed on top of

In Fig. 1, this conventional general lightning arrester is shown.

As illustrated, the lightning arrester 10 includes a support member 30 fixed to a building, a support portion 16 coupled to the support member 30, and a suction sphere 12 coupled to the support portion 16. It consists of).

The support member 30 is provided with a ground piece 34 for coupling a lightning conductor wire connected to a ground electrode (not shown).

The suction sphere 12 is coupled to the support 16 through the coupling groove 12a.

The suction part 16c constituting the support part 16 is comprised of the support rod 16a and the suction pin 16b provided in the side surface of the support bar 16a, and can absorb the shock current by the lightning strike from the side easily. It is supposed to be. Specifically, the suction part 16c is twisted after producing a plurality of suction pins 16b having a predetermined length in the plurality of support bars 16a in the longitudinal direction.

The conventional lightning protection device 10 for lightning is configured to suck the shock current through the suction sphere 12 and the suction pin 16b, and to ground the suction shock current to the upper surface of the support member 30. It is guide | induced to the earth through the lightning conductor wire grounded at the piece 34.

However, the lightning protection device for lightning protection, even if all the shock currents caused by lightning strikes to safely guide to the ground, because the impact current caused by lightning strikes is very large, communication of electronic products, especially buildings due to lightning induced lightning strikes Facilities, computers, weak electrical equipment, etc. were affected and there was a problem of failure or malfunction.

In order to solve such a problem, a lot of researches on the space charge distributed lightning arrester have been conducted recently. This is a device for preventing electric shock due to lightning by lowering the voltage flowing in the ground by preliminarily discharging and discharging the ground charging charges due to the thundercloud proximity.

Representative configurations thereof are shown in FIGS.

2 shows the configuration of the space charge distributed lightning arrester disclosed in Korean Utility Model Registration No. 305180.

As shown, the space charge distribution type lightning arrester 100 includes a support member 110, a discharge member 120, an isolation member 150, and the isolation member 150 with the support member 120 interposed therebetween. It is composed of a discharge cap 160 is coupled insulated. That is, the isolation member 150 is made of an insulating material such as plastic, and the discharge member 120 and the discharge cap 160, which are conductors, are disposed through the isolation member 150. In addition, the top cap 140 for fastening is coupled to the top.

Accordingly, when a thundercloud having a negative polarity approaches, the support member 110, the discharge member 120, and the upper cap 140 exhibit a positive polarity, and the discharge cap 160 has a negative polarity. It shows polarity. Then, a very high potential difference is generated between the discharge member 120 and the discharge cap 160, and corona discharge is generated in the air. As a result, the ground voltage is lowered, and electrical shock due to lightning can be prevented as much as possible. In addition, as mentioned above, it is based on the electric dipole principle by electrostatic induction which has mutually opposite electrodes.

In the drawing, since the discharge member 120 has a structure in which the discharge pins 128a are inserted between the plurality of twisted support rods 126a, the discharge pins 128a form a spiral arrangement. Preliminary discharge is better made by the discharge pin 128a.

When the support rod 126a is coupled to the upper cap 140 and the coupling protrusion 112 for fastening, additional components such as the connecting piece 124 and the fixing piece 122 are required.

3 shows the configuration of the space charge distributed lightning arrester disclosed in Korean Utility Model Utility Model No. 305185.

As shown, the other configuration is similar to that of FIG. 2 except that a plurality of discharge members 134 including the discharge pins 134a and the support rods 125 are radially provided.

4 shows the configuration of the space charge distributed lightning arrest apparatus disclosed in Korean Patent Utility Model Publication No. 305193.

As shown, except that the arrangement of the support member 104 and the discharge member 120 is different, the other configuration is similar to that of FIGS. 2 and 3. The principle is also the same.

5 shows the configuration of the space charge distributed lightning arrester disclosed in Korean Laid-Open Patent Publication No. 2003-0026913.

As shown, a conductor protection member 66 and a discharge assisting member 65 are additionally included between the isolation member 62 and the discharge cap 67. In addition, a distance correction member 70 is provided between the discharge member 40 and the potential relaxing means 60. Accordingly, when the thundercloud is close, corona discharge occurs between the cap (67) for discharging polarity and the distance correction member (70) for polarity. The rest of the configuration is similar to that of FIG. Here, the support rod 45 and the discharge pin 43 which are the same as the above-mentioned structure are provided below the distance correction member 70 so that preliminary discharge may be performed better.

However, in the conventional space charge distributed lightning arrester, there is a disadvantage that the process of manufacturing the discharge member is very complicated and cumbersome. That is, in a state where a plurality of discharge pins having a predetermined length are sandwiched between the plurality of wires, the wires must be twisted to form a spiral arrangement of the discharge wires. There must be a twisting process of the wire.

In addition, when the torsional support rod braided wire is coupled to the potential relaxation means or the distance correction member, etc., additional components such as the fixing piece or the connecting piece must be mediated.

The present invention has been made to solve the above problems, the object of the invention is to provide a space charge distributed lightning protection device having a simple structure, a simple production process and good pre-discharge performance.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

6 and 7 show the configuration of the space charge distributed lightning arrest apparatus according to the embodiment of the present invention.

As shown, the space charge distributed lightning arrester of the present embodiment, the support member 1100 is fixed to the bottom, the fixed rod 1200 is installed standing on the support member 1100, and the fixed rod 1200 Fastening means for supporting the fastening member 1300, the isolation member 1400, the discharge assisting member 1500, and the preliminary discharging member 1600, and the preliminary discharging member 1600 on the support member 1100. 1700.

The fastening member 1300 is a component coupled to the upper end of the fixing rod 1200 so that components constituting the discharge portion do not escape. Therefore, the fastening member 1300, as shown in the figure, may be composed of a cap member, may be composed of nuts and the like.

The isolation member 1400 is composed of two disk-shaped insulators having a gap, and a hollow tube 1410 is formed below. The fixing rod 1200 is fitted into the hollow tube 1410.

In addition, the discharge assisting member 1500 and the ring member 1800 are sequentially inserted into the outer surface of the hollow tube 1410. At this time, since the ring member 1800 is fitted in close contact with the hollow tube 1410, the discharge assisting member 1500 does not fall out due to its own weight. The ring member 1800 is made of an insulating material such as plastic.

Two discharge assisting members 1500 are arranged, and can exhibit a double layer effect, thereby facilitating a discharge time. In this case, when the insulating material layer A such as an epoxy resin is applied to the upper surface of the discharge assisting member 1500, the discharge becomes faster. Moreover, it is inclined downward toward the edge.

Meanwhile, the preliminary discharge member 1600 includes a discharge pin assembly 1650 and a discharge panel 1640 supporting the discharge pin assembly 1650.

First, the discharge pin assembly 1650 is composed of a plurality of discharge pins 1630 fitted in the coupling ring 1610 in the vertical direction. In detail, the discharge pin assembly 1650 may be manufactured by a simple process of inserting a plurality of discharge pins 1630 between two thin strips and then pressing each other.

The discharge pin assembly 1650 may be fixed to the discharge panel 1640 by welding, for example, on the opposite edge of the portion where the discharge pin 1630 is fitted, but may be brought into contact with each other in a separated state. If separated, shakes should be eliminated as much as possible.

The discharge pin assembly 1650 has a circular shape and is fitted to the outside of the ring member 1800. In this case, the discharge pin 1630 of the discharge pin assembly 1650 may be fitted in close contact with the ring member 1800. Of course, the discharge panel 1640 is formed with a hole to be fitted to the fixed bar (1200).

In this state, the vertical length of the discharge pin 1630 should be set appropriately so that a gap can be formed between the discharge pin assembly 1650 and the discharge assist member 1500.

Between the preliminary discharge member 1600 and the support member 1100, a support tube 1250 is interposed through a fixing rod 1200. In this configuration, no additional means for fixing the pre-discharge member 1600 to the fixing rod 1200 is required.

In addition, when viewed in a plan view, the isolation member 1400, the discharge assisting member 1500, the discharge pin assembly 1650, and the discharge panel 1640 are shown in a circular shape, but the edge thereof is somewhat square or the like. Variation of is possible.

In such a configuration, not only each component is very simple and easy to manufacture, but also the assembly process is simple, so that the productivity can be significantly higher than in the related art.

In FIG. 8, a discharge unit assembly 1000 including the isolation member 1400, the discharge assisting member 1500, the ring member 1800, and the discharge pin assembly 1650 is provided along the fixing rod 1200. The configuration in which more than one set is provided is shown.

In this case, a ring-shaped spacing member 1201 made of a conductor is provided between the discharge unit assembly 1000 and the discharge unit assembly 1000.

In addition, a support tube 1250 is interposed between the lowermost discharge part assembly 1000 and the support member 1100 through the fixing rod 1200.

9 shows an embodiment in which the fixing means 1700 is configured differently from the above-described embodiment.

As shown, an extension tube 1641 fitted to the fixed bar 1200 is formed below the discharge panel 1640, and a fixing screw portion 1641 is provided on a side surface of the extension tube 1641.

Accordingly, when a (-) polar thundercloud is approached to a building in which the space charge distributed lightning arrester of the present invention is installed, the fastening member 1300, the preliminary discharge member 1600, and the discharge are sequentially inserted into the fixed rod 1200. Positive charge is concentrated in the pin assembly 1650 and the discharge panel 1640, and the discharge assisting member 1500 insulated from these elements is charged with negative charge, and discharged with the discharge pin assembly 1650. The pre-discharge of the earth charge is generated in the space between the auxiliary members 1500, so that the earth potential value greatly drops.

According to the present invention of the configuration as described above, since the structure is simple and the production process is simple compared to the conventional space charge distributed lightning arrester, there is an advantage that the production cost is reduced and the productivity is also greatly increased.
