人工预防雷电危害自古有之,特别是200多年前发明了避雷针以来,人工防雷技术大大发展。目前我国的防雷产品就有上百个品种。雷电发生时,其放电电压可高达几千万伏,放电功率可高达3亿千瓦以上。据测算全球每年有31～125千万次闪电,雷击事故危害的立体性强,其损失也大。据不完全统计,我国每年雷电伤亡达万人以上,因此,预防和减少雷电事故,正是国防,石油
Artificial prevention of lightning hazards since ancient times, especially since more than 200 years ago invented the lightning rod, artificial lightning protection technology has greatly developed. At present, there are hundreds of varieties of lightning protection products in our country. Lightning occurs, the discharge voltage up to tens of millions of volts, the discharge power can be as high as 300 million kilowatts. It is estimated that there are 31 to 125 million lightning strikes in the world each year. The solidity of the lightning accident is so great that the loss is also large. According to incomplete statistics, there are more than 10 million lightning strikes each year in our country. Therefore, preventing and reducing lightning accidents is precisely the task of national defense and petroleum
