本考案は、襲雷警報器の集合コロナ針電極に関
する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a collective corona needle electrode for a lightning strike alarm.
コロナ電流と電界強度の関係は、第１図に示さ
れるごとくコロナ電流は電界の強さに比例するの
ではなく、コロナ電流Icは図中の実線のように変
化する。これを数式で示すと、
Ic＝ｋ（Ｘ−X0）2
となり、俗に〓二乗法則〓といわれる。
Regarding the relationship between corona current and electric field strength, as shown in Figure 1, the corona current is not proportional to the electric field strength, but the corona current Ic changes as shown by the solid line in the figure. Expressing this mathematically, Ic=k(X-X 0 ) 2 , which is commonly referred to as the square law.
従つて、コロナ電流によつて電界の変化を検出
することは、電波や誘導の妨害を受けないばかり
か鋭敏な検知能力をもつている。 Therefore, detecting changes in the electric field using corona current is not only free from interference from radio waves or induction, but also has a sensitive detection ability.
落雷の前には、電界強度が異常に高くなる。従
つて、コロナ針電極によつてコロナ電流を測定
し、コロナ電流が一定値をこえた場合に警報を出
すことができる。 Before a lightning strike, the electric field strength becomes abnormally high. Therefore, the corona current can be measured using the corona needle electrode, and an alarm can be issued if the corona current exceeds a certain value.
雷雲があるときは、一本の針先から出るコロナ
電流は、数マイクロアンペア程度はあるが、雷雲
の接近中には１本の針先から出るコロナ電流は
0.2マイクロアンペア以下のわずかな量である。 When there is a thundercloud, the corona current emitted from a single needle tip is about a few microamperes, but when a thundercloud is approaching, the corona current emitted from a single needle tip is about a few microamperes.
It is a small amount of less than 0.2 microampere.
本件出願人が開発したコロナ電流を利用した襲
雷警報器として多数のコロナ針をもつもの（第２
図）があるが、雷雲の接近を知るためには簡単で
あつてかえつて信頼度が高い。 A lightning strike warning device using corona current developed by the applicant with multiple corona needles (second
(Fig.) is a simple method for determining the approach of thunderclouds, but it is also highly reliable.
第２図において、１はコロナ針、２は中心が０
の設定針付のマイクロアンメーター、３はメータ
ーリレー、４は接地極、５は電源、６は警報器で
ある。 In Figure 2, 1 is the corona needle, 2 is the center is 0
3 is a meter relay, 4 is a grounding electrode, 5 is a power supply, and 6 is an alarm.
従来このような警報器のセンサー電極に関して
は、特開昭56−30294号〓コロナ電流発生用電極
装置〓がある。 Regarding sensor electrodes for such alarm devices, there is a conventional example of such sensor electrodes in Japanese Patent Application Laid-Open No. 56-30294 entitled Electrode Device for Generating Corona Current.
この装置においては、数本のシールド導体の上
部絶縁体からわずかに先端を露出した針を設けた
構成である。 This device has a configuration in which needles are provided with tips slightly exposed from the upper insulator of several shield conductors.
針は、球の表面に添つて配置されている。 The needle is placed along the surface of the sphere.
しかし、前記第２図の装置において、コロナ電
流が発生するか否かの境目に電流値に乱れが多い
のでそれを平均化するためには、少なくとも20〜
30本程度のコロナ針が必要であることが解つた。
However, in the device shown in Fig. 2, there are many disturbances in the current value at the boundary between whether or not a corona current is generated, so in order to average it out, it is necessary to
It turned out that about 30 corona needles were required.
しかも、単位面積当りの針の数が多くなると、
コロナ電流が飽和するという傾向があり、せつか
くコロナ電流を指標として用いた襲雷警報器の特
色が出せない。 Moreover, when the number of needles per unit area increases,
There is a tendency for the corona current to saturate, making it impossible to obtain the characteristics of a lightning warning system that uses corona current as an indicator.
そして一定の電界値をコロナ電流により検出す
るためには、コロナ針の針先の尖鋭度を均一とす
る必要があること等が分つてきた。 It has been found that in order to detect a constant electric field value using corona current, it is necessary to make the tip of the corona needle uniform in sharpness.
すなわち、針先が密集したり、針先の尖鋭度が
不揃いであるとか、使用中に錆て摩耗するなどの
点があれば、襲雷警報器に使用する雷センサーと
しては不適当である。 In other words, if the needle tips are crowded together, if the sharpness of the needle tips is uneven, or if it rusts and wears out during use, it is unsuitable as a lightning sensor for use in lightning alarms.
しかし、このような警報器のセンサー電極にお
いて、多数の針先を適切に分散させたもの、針先
を一定の尖鋭度にそろえたもの、昆虫や鳥害等に
耐えかつ一定期間使用して針先が摩耗する前に交
換できる構成のものはなかつた。 However, the sensor electrodes of such alarm devices have many needle tips that are appropriately distributed, needle tips that are aligned to a certain sharpness, and those that can withstand insect and bird damage and are used for a certain period of time. There was no structure in which the tip could be replaced before it wore out.
さらに多数本の針先を常に一定の尖鋭度に維持
管理することは実際上困難であつた。 Furthermore, it is actually difficult to maintain and control the tips of a large number of needles to a constant sharpness.

２はテーパー付の小突起であり、適当な間隔を
おいて、放射状に電極本体１の表面に立設されて

Therefore, the electric field strength can be measured under constant conditions.
コロナ針電極のセンサーを屋外に設置する場

必ずしも頂上から作用するとは限らず斜めからの
ものもあるが、本考案のものでは電界が垂直でな
い場合でも感度の上ではなはだ有利である。 When a corona needle electrode sensor is installed outdoors, the electric field from a thundercloud does not necessarily act from the top, but may act from an angle, depending on the topography and installation conditions. However, with the device of this invention, if the electric field is not vertical. However, it has a significant advantage in terms of sensitivity.
