Description

Dipole Lightning Arrester with Flat Ground Electrode

According to the present invention, when the thundercloud has a (+) charge, and when the thundercloud has a (-) charge, the flashover voltage occurs according to the polarity of the thundercloud, thereby minimizing the deviation of the flashover eye and structurally simple dipole. It relates to a lightning arrester.

The pattern in which an avalanche occurs during corona discharge, in which discharge through the air layer is broken between the charged electrodes in a state where high voltage is charged between both ends, causes a discharge,

 First, a positive voltage is applied to the precipitation electrode, which is one of the electrodes to which high voltage is charged, and the other is a flat electrode, and an electric avalanche occurs when the earth is grounded to the ground. , As shown in FIG.

[Correction under Article 91 of the Rule 15.11.2016]

In the form of a cation (+) as shown in FIG. 5 (a), the electrons that have escaped are collected around the settling electrode, and a primary electron event occurs in which a cation is formed in a shape that gradually shrinks toward the plate electrode. In the vicinity, a mixed ion region in which a cation and an electron group are mixed is formed, and secondary avalanches of the type shown in FIG. 5 (b) are performed.

[Correction under Article 91 of the Rule 15.11.2016]
Next, as the negative ions are concentrated in the direction of the plate electrode in the mixed ion region, a glow discharge of the form as shown in FIG. 5 (c) is started, and the primary electron avalanche and the second electron are described again in the electron group region toward the plate electrode. As it progresses to the glow discharge through the situation and proceeds to the shape as shown in FIG. 5 (d) distributed around, light is emitted while a breakdown streamer is formed from the precipitation electrode toward the flat electrode.

If you apply it to a lightning protection device

The needle electrode corresponds to an electrode grounded to the earth to which the positive charge is charged, and the plate electrode charged to the negative charge corresponds to the thundercloud.

[Correction under Article 91 of the Rule 15.11.2016]
Therefore, the existing conventional lightning rod takes the form of a needle electrode based on this.

[Correction under Article 91 of the Rule 15.11.2016]
have.

[Correction under Article 91 of the Rule 15.11.2016]
Next, a negative voltage is applied to the needle electrode, which is one of the electrodes to which the high voltage is charged, and the other is applied as a flat plate electrode between the electrodes in the state of being grounded to the ground, whereby an avalanche is generated and insulation between the final electrodes If you look at the discharge process,

[Correction under Article 91 of the Rule 15.11.2016]
In the form of cations (+) and electrons, as shown in FIG. It is heavier than the former, so it is evenly distributed in the reader shape.

[Correction under Article 91 of the Rule 15.11.2016]
Since the electrons are lighter on the positive electrode of the positive electrode, all of them are easily formed in the form of an aggregate of electrons. The process of the glow discharge in the charged state is concentrated as the positron is gradually diffused toward the settling pole and the positive charge density is lowered in the portion away from the settling pole, thus the electrons are also dispersed around the cation which is lowered in density. It proceeds to the shape as shown in b).

[Correction under Article 91 of the Rule 15.11.2016]
Thereafter, the anion and the cation are repeated between the electrodes to form a breakdown streamer as shown in FIG. 6 (c), and the light is emitted.

In view of the above, even if the electrode has the same electrode structure, it can be seen that the development of flashover is different depending on the polarity of the voltage applied to each electrode.

Despite this, a conventional lightning arrester in which the grounded electrode is in the form of a sedimentary pole is used, and the present inventors also implement a lightning arrester using a dipole principle for reducing the probability of direct lightning strike, Has developed
