Description

本発明は、雷害から設備機器等を保護するための避雷装置に関するものであり、特に、設備機器等周辺の落雷を避けるための避雷装置に関するものである。   The present invention relates to a lightning arrester for protecting equipment and the like from lightning damage, and more particularly to a lightning arrester for avoiding lightning strikes around the equipment and the like.

大気中に雷雲が発生し発達すると、雷雲の雲底から先行放電(ステップリーダ)が大地に向かって発生し、この先行放電が進展すると、地表面側から、先行放電の電荷と反対の電荷を有するストリーマ放電が上昇する。そして、先行放電とストリーマ放電が結合すると、大地と雷雲との間に放電路が形成され、この放電路を通って、大地と雷雲との間に大電流が流れる。この現象が落雷現象である。   When thunderclouds are generated and developed in the atmosphere, a leading discharge (step leader) is generated from the thundercloud's cloud bottom toward the ground, and when this leading discharge progresses, a charge opposite to that of the preceding discharge is generated from the ground surface side. The streamer discharge is increased. When the preceding discharge and the streamer discharge are combined, a discharge path is formed between the ground and the thundercloud, and a large current flows between the ground and the thundercloud through the discharge path. This phenomenon is a lightning phenomenon.

従来の避雷装置は、建造物を含む設備機器等の被保護対象物より高い位置に配置された避雷突針で落雷を受けて、大電流を、大地に吸収するように構成されており、落雷を避雷突針が受けることで、被保護対象物に落雷が生じないように構成されている。   Conventional lightning arresters are configured to receive a lightning strike with a lightning striker located at a higher position than the object to be protected such as equipment including buildings, and to absorb a large current to the ground. It is configured so that no lightning strikes the object to be protected by receiving the lightning strike needle.

落雷を、被保護対象物より高い位置に配置した避雷突針で受けて、雷雲と大地間の絶縁破壊で起きる落雷を吸収する従来の避雷装置は、被保護対象物への直撃雷を回避することはできるが、落雷自体を無くすことは極めて困難である。     A conventional lightning arrester that receives lightning strikes with a lightning striker located higher than the object to be protected and absorbs lightning strikes caused by insulation breakdown between the thundercloud and the ground must avoid direct lightning strikes on the object to be protected. Although it is possible, it is extremely difficult to eliminate the lightning strike itself.

従来の避雷突針に変え、雷雲と対向する上面を、突針部のない面状の放電面部として形成して、多くの放電点を形成し、一度に多量の電荷を、弱い勢いで放電することにより、先行放電と雷雲の電荷が極めて結合し難くなり、大電流の帰還電流を抑え、落雷による被保護対象物の損傷を最小限にする提案が、本出願人によりなされた。   By replacing the conventional lightning arrester needle with the upper surface facing the thundercloud as a planar discharge surface part without the needle part, forming many discharge points, and discharging a large amount of charge at once with a weak momentum The applicant has made a proposal that makes it difficult to combine the preceding discharge with the thundercloud charge, suppresses a large feedback current, and minimizes damage to the object to be protected by lightning strikes.

このような、雷雲と対向する上面を、面状の放電面部として形成し、大電流の帰還電流を抑えることができる避雷装置が、一例として、本出願人の先の出願である特許文献1に開示されている。   An example of such a lightning arrester in which the upper surface facing the thundercloud is formed as a planar discharge surface portion and can suppress a large feedback current is disclosed in Patent Document 1, which is an earlier application of the present applicant. It is disclosed.

特開2008−10241号公報JP 2008-10241 A

落雷自体を無くすことは極めて困難であり、避雷極部材に、雷雲が近づいた際には、上部電極体が、雷雲に分布する電荷を有する下部電極体との電位差を、周辺の大気中から収集することになり、従って、雷雲に分布する電荷が飽和するようなことを防止することができ、落雷の発生を回避することができるが、落雷自体を無くすことはできない。 It is extremely difficult to eliminate the lightning strike itself, and when a thundercloud approaches the lightning pole member, the upper electrode body collects the potential difference from the lower electrode body with charges distributed in the thundercloud from the surrounding atmosphere. Therefore, it is possible to prevent the electric charge distributed in the thundercloud from being saturated and to avoid the occurrence of a lightning strike, but the lightning strike itself cannot be eliminated.

従来の上部電極体と下部電極体と環状絶縁体とからなる避雷装置においては、落雷による大電流が、上部電極体から、下部電極体を介して、大地に吸収されることになるが、放電時間の長いエネルギーの大きい雷の場合、上部電極体と環状絶縁体との間及び下部電極体と環状絶縁体との間に、過大な電圧が加わり、環状絶縁体の絶縁破壊を生じ、避雷装置の機能の低下をきたすという問題があった。   In a conventional lightning arrester composed of an upper electrode body, a lower electrode body, and an annular insulator, a large current due to a lightning strike is absorbed from the upper electrode body through the lower electrode body to the ground. In the case of lightning with a long time and large energy, an excessive voltage is applied between the upper electrode body and the annular insulator and between the lower electrode body and the annular insulator, causing dielectric breakdown of the annular insulator, and a lightning arrester. There was a problem of causing a decline in the function of.

また、上部電極体と環状絶縁体及び下部電極体と環状絶縁体とは、それぞれ、ボルトにて取り付けていたので、上部電極体と下部電極体との絶縁距離が短く、従って、環状絶縁体が絶縁破壊されるという問題があった。   Further, since the upper electrode body and the annular insulator and the lower electrode body and the annular insulator are respectively attached with bolts, the insulation distance between the upper electrode body and the lower electrode body is short, and therefore the annular insulator is There was a problem of dielectric breakdown.

更に、上部電極体の天部中央に上部凸部を形成するとともに、下部電極体の底部中央部に下部凸部を形成し、且つ、上部電極体と上部凸部とが一体に形成されているとともに、下部電極体と下部凸部とが一体に形成されているので、上部電極体と下部電極体とを任意の間隔で取り付けることができず、従って、上部電極体と下部電極体との間の放電が、迅速に、且つ、確実に行われずに、環状絶縁体の絶縁破壊による絶縁低下を起すという問題があった。   Furthermore, an upper convex portion is formed at the center of the top portion of the upper electrode body, a lower convex portion is formed at the central portion of the bottom portion of the lower electrode body, and the upper electrode body and the upper convex portion are integrally formed. In addition, since the lower electrode body and the lower protrusion are integrally formed, the upper electrode body and the lower electrode body cannot be attached at an arbitrary interval. There is a problem in that the electrical discharge is not promptly and surely performed and the insulation is lowered due to the dielectric breakdown of the annular insulator.

本発明の目的は、上述した従来の避雷装置が有する課題を解決することにある。   The objective of this invention is solving the subject which the conventional lightning arrester mentioned above has.

本発明は、上述した目的を達成するために、避雷装置を、上部電極体に形成された上部凹部を囲むように配置された上部放電電極体と、下部電極体に形成された下部凹部を囲むように配置された下部放電電極体とにより構成するとともに、更に、上部電極体と下部電極体とにより挟持された円筒状絶縁体と、円筒状絶縁体に嵌合された絶縁保持体とを配設したものである。   In order to achieve the above-described object, the present invention surrounds a lightning arrester with an upper discharge electrode body disposed so as to surround an upper recess formed in the upper electrode body and a lower recess formed in the lower electrode body. And a cylindrical insulator sandwiched between the upper electrode body and the lower electrode body, and an insulating holding body fitted to the cylindrical insulator. It is set.

本発明は、上述した構成を有しているので、以下に記載する効果を奏することができる。   Since this invention has the structure mentioned above, there can exist the effect described below.

避雷装置を、上部電極体に形成された上部凹部を囲むように配置された上部放電電極体と、下部電極体に形成された下部凹部を囲むように配置された下部放電電極体とにより構成するとともに、更に、上部電極体と下部電極体とにより挟持された円筒状絶縁体と、円筒状絶縁体に嵌合された絶縁保持体とを配設したので、避雷極部材に、雷雲が近づいた際には、上部電極体が、雷雲に分布する電荷と反対の電荷を有する下部電極体との電位差を解消するように働くため、上部電極体が、下部電極体の電荷と反対の電荷を、周辺の大気中から取り入れることになるので雷雲に分布する電荷が飽和するようなことを防止することができ、よって、落雷の発生を回避することができる。   The lightning arrester is composed of an upper discharge electrode body disposed so as to surround an upper recess formed in the upper electrode body, and a lower discharge electrode body disposed so as to surround a lower recess formed in the lower electrode body. In addition, since a cylindrical insulator sandwiched between the upper electrode body and the lower electrode body and an insulating holding body fitted to the cylindrical insulator are disposed, a thundercloud approaches the lightning protection pole member. In this case, since the upper electrode body works so as to eliminate the potential difference with the lower electrode body having the charge opposite to the charge distributed in the thundercloud, the upper electrode body has a charge opposite to the charge of the lower electrode body. Since the air is taken from the surrounding atmosphere, it is possible to prevent the electric charge distributed in the thundercloud from being saturated, and thus it is possible to avoid the occurrence of lightning.

また、上部電極体に落雷が発生した場合、上部電極体の上部放電電極体から下部電極体の下部放電電極体とで、放電時間の長くエネルギーの大きい雷に対しても、例えば、設置する環境に対応して、予め、上部放電電極体と下部放電電極体との間隙距離を任意に設定することが容易にでき、放電時間が長くエネルギーの大きい雷に対しても、放電動作を早く確実に処理することができ、円筒状絶縁体に与える高電圧の影響を小さくすることができ、結果的に、円筒状絶縁体の絶縁破壊を防止でき、確実に処理できる。   In addition, when a lightning strike occurs in the upper electrode body, for example, in the environment where the lightning discharge is long and the energy is large between the upper discharge electrode body of the upper electrode body and the lower discharge electrode body of the lower electrode body. The gap distance between the upper discharge electrode body and the lower discharge electrode body can be easily set in advance, and the discharge operation can be performed quickly and reliably even for lightning with a long discharge time and high energy. Therefore, the influence of the high voltage on the cylindrical insulator can be reduced, and as a result, the dielectric breakdown of the cylindrical insulator can be prevented and the processing can be reliably performed.

更に、上部電極体と下部電極体とを狭持する円筒状絶縁体に嵌合された絶縁保持体を配設したことにより、大気中の筒状絶縁体の外周縁間の放電を回避することができ、従って、放電による絶縁破壊を防止でき、避雷装置の信頼性が向上する。   Furthermore, by disposing an insulating holder fitted to a cylindrical insulator that sandwiches the upper electrode body and the lower electrode body, discharge between the outer peripheral edges of the cylindrical insulator in the atmosphere is avoided. Therefore, dielectric breakdown due to electric discharge can be prevented, and the reliability of the lightning protection device is improved.

上部電極体に取着された上部放電電極体と下部電極体に取着された下部放電電極体による放電間隔を容易に設定することができるので、早く確実に放電設定ができるとともに、上部放電電極体と下部放電電極体と円筒状絶縁体との距離が大きく得られるので、円筒状絶縁体の絶縁破壊を、相乗的により確実に防止することができ、寿命の長い信頼性に優れた避雷装置を提供することができる。   The discharge interval between the upper discharge electrode body attached to the upper electrode body and the lower discharge electrode body attached to the lower electrode body can be easily set, so that the discharge can be set quickly and reliably, and the upper discharge electrode Since the distance between the body, the lower discharge electrode body and the cylindrical insulator is large, the dielectric breakdown of the cylindrical insulator can be prevented synergistically and surely, and the lightning protection device with long life and excellent reliability Can be provided.

上部電極体と下部電極体との間に配設された円筒状絶縁体に、絶縁保持体を嵌合したことにより、大気中に面した円筒状絶縁体が、外気の気候の影響を受け難く、且つ、絶縁保持体の連結環状フランジにより、沿面距離を大きくすることができるので、大気中の放電も回避することができ、従って、寿命の長い信頼性に優れた避雷装置を提供することができる。   The cylindrical insulator disposed between the upper electrode body and the lower electrode body is fitted with an insulating holder, so that the cylindrical insulator facing the atmosphere is hardly affected by the climate of the outside air. In addition, since the creeping distance can be increased by the connecting annular flange of the insulating holder, it is possible to avoid discharge in the atmosphere, and therefore to provide a lightning protection device with a long life and excellent reliability. it can.

上部放電電極体と下部放電電極体に穿設された透孔により、上部電極体に形成された上部凹部と、下部電極体に形成された下部凹部及び円筒状絶縁体に囲まれた中央部との空間が一体となり、ゆえに当該空間が略同一気圧となり、従って、避雷装置の安定した放電動作ができる。   An upper recess formed in the upper electrode body by a through-hole drilled in the upper discharge electrode body and the lower discharge electrode body, and a lower recess formed in the lower electrode body and a central portion surrounded by the cylindrical insulator Therefore, the spaces are at substantially the same pressure, so that the lightning arrester can be stably discharged.

Reference numeral 11 denotes an intermediate fitting. The intermediate fitting 11 includes a cylindrical portion 11a and a top portion 11b, and a through-hole through which the conductive connecting screw rod 8 can be inserted in the center portion of the top portion 11b. 11b1 is drilled.

次に、避雷極部材1を構成する上部電極体2、下部電極体3、円筒状絶縁体4及び絶縁保持体5等の組み立てについて説明する。   Next, assembly of the upper electrode body 2, the lower electrode body 3, the cylindrical insulator 4, the insulating holder 5, and the like constituting the lightning protection pole member 1 will be described.

先ず最初に、上部放電電極体6が取着された上部電極体2の環状溝2b2に、円筒状絶縁体4の上端部を嵌合するとともに、円筒状絶縁体4に、絶縁保持体5の内側円筒体5aを嵌合させる。耐候性や耐熱性や接着力に優れたエポキシ系の接着剤を用いて、上部放電電極体6が取着された上部電極体2の環状溝2b2に、円筒状絶縁体4の上端部を取り付けることもできる。次いで、下部放電電極体7が取着された下部電極体3の環状溝3b2に、円筒状絶縁体4の下端部を嵌合させる。耐候性や耐熱性や接着力に優れたエポキシ系の接着剤を用いて、下部放電電極体7が取着された下部電極体3の環状溝3b2に、円筒状絶縁体4の下端部を取り付けることもできる。   First, the upper end of the cylindrical insulator 4 is fitted into the annular groove 2b2 of the upper electrode body 2 to which the upper discharge electrode body 6 is attached, and the insulating holder 5 is attached to the cylindrical insulator 4. The inner cylindrical body 5a is fitted. The upper end portion of the cylindrical insulator 4 is attached to the annular groove 2b2 of the upper electrode body 2 to which the upper discharge electrode body 6 is attached using an epoxy adhesive having excellent weather resistance, heat resistance and adhesive strength. You can also. Next, the lower end portion of the cylindrical insulator 4 is fitted into the annular groove 3b2 of the lower electrode body 3 to which the lower discharge electrode body 7 is attached. A lower end portion of the cylindrical insulator 4 is attached to the annular groove 3b2 of the lower electrode body 3 to which the lower discharge electrode body 7 is attached using an epoxy adhesive having excellent weather resistance, heat resistance and adhesive strength. You can also.

上述したように、上部放電電極体6が取着された上部電極体2と円筒状絶縁体4と絶縁保持体5と下部放電電極体7が取着された下部電極体3とが組み立てられた際には、絶縁保持体5の連結環状フランジ5cの上面が、上部電極体2の下端水平環状フランジ2cの下面に面接触するように構成されているとともに、絶縁保持体5の外側円筒体5bと下部電極体3の上端水平環状フランジ3cとの間には、間隙D1が形成されるように構成されている。換言すれば、絶縁保持体5の外側円筒体5bは、上部電極体2の下端水平環状フランジ2c及び下部電極体3の上端水平環状フランジ3cより、外側に位置するように構成されている。   As described above, the upper electrode body 2 to which the upper discharge electrode body 6 is attached, the cylindrical insulator 4, the insulating holding body 5, and the lower electrode body 3 to which the lower discharge electrode body 7 is attached are assembled. In this case, the upper surface of the connecting annular flange 5c of the insulating holding body 5 is configured to be in surface contact with the lower surface of the lower horizontal annular flange 2c of the upper electrode body 2, and the outer cylindrical body 5b of the insulating holding body 5 is used. A gap D1 is formed between the upper electrode 3 and the upper horizontal flange 3c of the lower electrode body 3. In other words, the outer cylindrical body 5 b of the insulating holding body 5 is configured to be located outside the lower end horizontal annular flange 2 c of the upper electrode body 2 and the upper end horizontal annular flange 3 c of the lower electrode body 3.

次に、導電性接続ネジ棒8の上端部を、下部電極体3に形成された取付用ネジ孔3dに螺合することにより、下部電極体3に、導電性接続ネジ棒8を接続し、その後、導電性接続ネジ棒8に、絶縁部材9に形成された縦長貫通孔9aを挿通して、下部電極体3bと絶縁部材9とが連接されることになるが、この際には、下部電極体3に形成されているネジ孔3eと絶縁部材9の上部フランジ9bに形成されているガス栓用穴9cとにより構成される空間部に、上述したように、ガス抜用のガス栓Gが配設されることになる。   Next, the conductive connection screw rod 8 is connected to the lower electrode body 3 by screwing the upper end portion of the conductive connection screw rod 8 into the mounting screw hole 3d formed in the lower electrode body 3, Thereafter, the vertically long through hole 9a formed in the insulating member 9 is inserted into the conductive connecting screw rod 8, and the lower electrode body 3b and the insulating member 9 are connected to each other. As described above, in the space formed by the screw hole 3e formed in the electrode body 3 and the gas plug hole 9c formed in the upper flange 9b of the insulating member 9, the gas plug G for venting gas is used. Will be disposed.

次いで、絶縁部材9の下部フランジ9dに形成された凹部9d1内に位置する導電性接続ネジ棒8に、ワッシャWとスプリングワッシャSWを挿入するとともに、導電性接続ネジ棒8に、ナットNを螺合させることにより、絶縁部材9を取り付ける。その後、絶縁部材9の下部フランジ9dに形成された凹部9d1に、導電性接続ネジ棒8を囲むように、円筒状保護体10の上端部を嵌合する。次いで、中間金具11の天部11bに穿設された透孔11b1に、導電性接続ネジ棒8を挿入するとともに、円筒状保護体10の下端部に、中間金具11の円筒部11aを嵌合させるとともに、中間金具11の円筒部11a内に位置する導電性接続ネジ棒8に、ワッシャWとスプリングワッシャSWを挿入するとともに、導電性接続ネジ棒8に、ナットNを螺合させることにより、円筒状保護体10を取り付ける。   Next, the washer W and the spring washer SW are inserted into the conductive connection screw rod 8 located in the recess 9 d 1 formed in the lower flange 9 d of the insulating member 9, and the nut N is screwed into the conductive connection screw rod 8. The insulating member 9 is attached by combining. Thereafter, the upper end portion of the cylindrical protective body 10 is fitted into the recess 9 d 1 formed in the lower flange 9 d of the insulating member 9 so as to surround the conductive connection screw rod 8. Next, the conductive connection screw rod 8 is inserted into the through hole 11b1 formed in the top portion 11b of the intermediate metal piece 11, and the cylindrical portion 11a of the intermediate metal piece 11 is fitted to the lower end portion of the cylindrical protective body 10. And by inserting the washer W and the spring washer SW into the conductive connection screw rod 8 located in the cylindrical portion 11a of the intermediate fitting 11, and screwing the nut N into the conductive connection screw rod 8, A cylindrical protective body 10 is attached.

上述したようにして、避雷極部材1を構成する上部電極体2、下部電極体3、円筒状絶縁体4及び絶縁保持体5等が組み立てられることになる。   As described above, the upper electrode body 2, the lower electrode body 3, the cylindrical insulator 4, the insulating holder 5, and the like that constitute the lightning pole member 1 are assembled.

その後、導電性接続ネジ棒8の下端部に、導電性を有する連結フランジF1を、適当数、螺合させるとともに、適当数の碍子H1を介して、避雷極部材1が、支持体Tに配設されることになる。   Thereafter, an appropriate number of conductive connecting flanges F1 are screwed onto the lower end of the conductive connection screw rod 8, and the lightning pole member 1 is disposed on the support T via an appropriate number of insulators H1. Will be established.

なお、Lは、導電性を有する連結フランジF1に、その上端部が、電気的に接続された引下げ線であり、引下げ線Lは、図示されていない大地に配設された接地極体に接続されており、全体として、避雷装置が構成されることになる。   Note that L is a pull-down line electrically connected to the conductive connecting flange F1 at its upper end, and the pull-down line L is connected to a grounding pole body arranged on the ground (not shown). As a whole, a lightning arrester is constructed.

次に、上述した避雷装置の動作について説明する。   Next, the operation of the above lightning arrester will be described.

雷雲が発生し、雷雲が、避雷装置に近づくと、大地の表面には、雷雲の雲底に分布する電荷と反対の電荷が分布することになる。そして、大地の表面に分布した電荷が、飽和レベルに達すると、大地に設置された接地極体及び引下げ線Lを介して、大地と等電位の避雷極部材1を構成する下部電極体3に、雷雲の電荷と反対の電荷が集まることになる。一方、上部電極体2は、下部電極体3との電位差を解消するために、下部電極体3の電荷と反対の電荷を、周辺の大気中から収集する。   When a thundercloud is generated and the thundercloud approaches the lightning arrester, a charge opposite to the charge distributed on the bottom of the thundercloud is distributed on the surface of the ground. Then, when the charge distributed on the surface of the earth reaches a saturation level, the lower electrode body 3 constituting the lightning pole member 1 having the same potential as the ground is connected to the ground via the grounding pole body and the pull-down line L installed on the ground. The charge opposite to that of thundercloud will be collected. On the other hand, the upper electrode body 2 collects the charge opposite to the charge of the lower electrode body 3 from the surrounding atmosphere in order to eliminate the potential difference with the lower electrode body 3.

上部電極部2の電荷と、下部電極体3の電荷とは、円筒状絶縁体4を通じて、上部電極体2に取着された上部放電電極体6と下部電極体3に取着された下部放電電極体7との間で、一方の電荷と該電荷と反対のもう一方の電荷の電荷移動が始まり、その後、次第に、電荷移動が、上部電極体2と下部電極体3の全体に拡がり、電荷同士が活発に動き、また、円筒状絶縁体4を介して、電荷の移動が生じる。そして、更に、雷雲が、避雷装置に近づくと、電荷レベルが更に活発に動き、小電流を流すとともに、避雷極部材1の周辺の大気中から、上部電極体2が、電荷を活発に収集して、避雷極部材1の周辺の大気中の前記電荷と反対の電荷の飽和を解消し、従って、落雷の発生が回避されることになる。このように、上部電極体2の上部放電電極体6と下部電極体3の下部放電電極体7との間での電荷移動が、確実に、且つ、迅速に開始することになる。   The charge of the upper electrode part 2 and the charge of the lower electrode body 3 are, through the cylindrical insulator 4, the upper discharge electrode body 6 attached to the upper electrode body 2 and the lower discharge attached to the lower electrode body 3. The charge transfer of one charge and the other charge opposite to the charge starts with the electrode body 7, and then the charge transfer gradually spreads over the entire upper electrode body 2 and the lower electrode body 3. They move actively, and charge transfer occurs through the cylindrical insulator 4. Further, when the thundercloud approaches the lightning arrester, the charge level moves more actively, a small current flows, and the upper electrode body 2 actively collects the charge from the atmosphere around the lightning pole member 1. Thus, the saturation of the electric charge opposite to the electric charge in the atmosphere around the lightning protection electrode member 1 is eliminated, and therefore the occurrence of lightning strike is avoided. Thus, the charge transfer between the upper discharge electrode body 6 of the upper electrode body 2 and the lower discharge electrode body 7 of the lower electrode body 3 starts reliably and rapidly.

上述したように、避雷極部材1に雷雲が近付くと、大地の表面に雷雲の雲底に分布する電荷と反対の電荷が分布するようになる。そして、大地の表面に分布した電荷が、飽和レベルに達すると、大地に設置された接地極体及び引下げ線Lを介して、大地と等電位の避雷極部材1の構成する下部電極体3に集まることになる。一方、上部電極体2は下部電極体3との電位差を解消するため、周囲から下部電極体3に集められた電荷の反対の電荷を集める。従って、大気中の電荷の飽和を解消するので、落雷の発生を回避することができる。しかし、収集された電荷が極めて大きい場合には、広面積を有する面状の放電面部として形成された避雷極部材1の広面部から夏期雷時にはストリーマ放電を、冬季雷時には先行放電を生じることもあるが、図示されていない絶縁ケーブルが持つインピーダンスにより、地表から引き寄せられる電荷量が制限される。よって、避雷極部材1の広面部にある多くの放電点から多量の電荷が弱い勢いで放電されるため、ストリーマ放電や先行放電は共に放電距離が短くなり、雷雲からの放電と結合しにくくなる。ゆえに、大電流を伴うリターンストローク(帰還電撃)には至らず、大きな被害を被る落雷を回避できる。   As described above, when a thundercloud approaches the lightning pole member 1, a charge opposite to the charge distributed on the cloud bottom of the thundercloud is distributed on the surface of the ground. Then, when the electric charge distributed on the surface of the earth reaches a saturation level, the ground electrode body and the pull-down line L installed on the ground are connected to the lower electrode body 3 constituting the lightning pole member 1 having the same potential as the earth. Will be gathered. On the other hand, the upper electrode body 2 collects charges opposite to those collected in the lower electrode body 3 from the periphery in order to eliminate the potential difference with the lower electrode body 3. Therefore, since the saturation of electric charges in the atmosphere is eliminated, the occurrence of lightning can be avoided. However, when the collected charge is extremely large, streamer discharge may occur during a lightning in the summer from the wide surface portion of the lightning pole member 1 formed as a planar discharge surface portion having a large area, and a preceding discharge may occur during a lightning in the winter. However, the amount of charge drawn from the ground surface is limited by the impedance of the insulated cable (not shown). Therefore, since a large amount of charge is discharged from a large number of discharge points on the wide surface portion of the lightning protection electrode member 1 with a weak momentum, both the streamer discharge and the preceding discharge have a short discharge distance and are difficult to combine with the discharge from the thundercloud. . Therefore, it does not reach a return stroke (return electric shock) with a large current, and it is possible to avoid a lightning strike that causes a great damage.

また、落雷に伴う接地抵抗による大地電位上昇があっても、落雷自体が小さいので大地電位上昇を低く抑えられるメリットがある。   Moreover, even if there is a ground potential increase due to grounding resistance due to a lightning strike, there is an advantage that the ground potential rise can be suppressed low because the lightning strike itself is small.

更にまた、例えば、冬季の日本海側においては、稀に想像を越す大きな落雷が連続して生じることがあり、このような場合、円筒状絶縁体4に、放電を生じさせて絶縁破壊を生じさせることがあるが、上部電極体2の上部放電電極体6と下部電極体3の下部放電電極体7との空間部の放電間隙の調整が容易となり、早い放電で低い放電電圧にでき、上部電極体2と下部電極体3との放電極間電圧を低い電圧にでき、円筒状絶縁体4に加わる電圧が小さく、よって、円筒状絶縁体4の絶縁破壊を防止でき、更に、円筒状絶縁体4と上部電極体2及び下部電極体3の取付にボルトを無くして接着としたことで、絶縁距離が拡大され、想像を超える過大な雷に対しても、絶縁破壊を防止でき、寿命の長い信頼性の向上がある避雷装置を実現することができる。   Furthermore, for example, on the Sea of Japan side in the winter season, rarely large lightning strikes beyond imagination may occur continuously. In such a case, the cylindrical insulator 4 is caused to discharge and cause dielectric breakdown. However, the adjustment of the discharge gap in the space between the upper discharge electrode body 6 of the upper electrode body 2 and the lower discharge electrode body 7 of the lower electrode body 3 is facilitated, and a low discharge voltage can be achieved by rapid discharge. The voltage between the discharge electrodes of the electrode body 2 and the lower electrode body 3 can be made low, the voltage applied to the cylindrical insulator 4 is small, so that the dielectric breakdown of the cylindrical insulator 4 can be prevented, and further the cylindrical insulation By attaching bolts to the body 4 and the upper electrode body 2 and the lower electrode body 3 without using bolts, the insulation distance is expanded, and it is possible to prevent insulation breakdown against excessive lightning beyond imagination, Realize a lightning arrester with long reliability improvement It can be.

避雷極部材1に、雷雲の近づく状況下で、上部電極体2が、大地と接続された下部電極体3と反対の電荷を周辺の大気中から収集するので、雷雲がより近づいてストリーマが放電し、落雷が生じても大気中の電荷を吸収している状況下であり、よって、放電時間は短くでき、落雷の処理時間を早くでき、大きい落雷を未然に防止する効果を有する。   Under conditions where a thundercloud is approaching the lightning pole member 1, the upper electrode body 2 collects charges opposite to the lower electrode body 3 connected to the ground from the surrounding atmosphere, so the thundercloud approaches and the streamer discharges. However, even if a lightning strike occurs, the electric charge in the atmosphere is absorbed. Therefore, the discharge time can be shortened, the lightning treatment time can be shortened, and the large lightning strike can be prevented.

また、避雷極部材1の形状を、落雷頻度、大きさ、設備機器等を考慮して落雷の状況にあった選択ができ、避雷装置のコスト低減の対応ができる。   In addition, the shape of the lightning protection pole member 1 can be selected in accordance with the lightning strike situation in consideration of the lightning strike frequency, size, equipment, etc., and it is possible to reduce the cost of the lightning arrester.
