消雷器能否消雷的分析

WHETHER LIGHTNING ELIMINATOR CAN ELIMINATE LIGHTNING STROKE

武当山金顶庙已有540多年历史，未被雷击过，这一直被当成自然界消雷成功的一个典型例子。本文以金顶庙消雷模拟实验为依据，提出了只有在特殊条件下，“中和”电流才能消除雷击的看法。对肯定消雷功能的文献进行了分析，包括：消雷的定义，“中和”与“限流”消雷机理、消雷器的保护范围、消雷器防雷效果分析，指出了其中存在的问题及支持消雷的文献中给出的有关数值是不可信的。把消雷器及其被保护物未遭雷击，说成是消雷的成功是不正确的，在一般情况下消雷是实现不了的。

There is an old temple named 'Jinding' locatedin Wudang Mountain, Hubei Province, which has never beenstruck by lightning during the period of past 540 years. ThisPhenomenon is regarded as a typical successful example oflightning e1iminator in nature. Based on the lightning eliminat-ing simulation test of 'Jinding Temple',a conc1usion of light-ning eIiminating is obtained that lightning stroke can not be e-liminated by neutralizing the charge in thunder stone cell un-less some very special conditions exist. The author analyzes thedefinition of the lightning elimination, the lightning e1imina-tion mechanism of neutralization and current limiation, theprotection zone of lightning eliminator, puts forward someproblems about the above mentioned respects, and points outthat the data in the literatures which affirm the lightning elim-inators are untrustworthy. The author emphasizes that it is notexact to regard the phenomena that the lightning eliminator it-self and the objects being protected have not been struck as asuccessful example of lightning elimination, and generally, un-der ordinary condition the lightning elimination is only an un-realistic viewpoint.
