消雷器的运行实效及消雷机理的试验探索

The Operation Effects of Lightning Eliminators and the Tests for the Mechanism of Lightning Elimination

金属消雷器在云南的运行取得了良好的实效。为探索消雷机理用体积电荷雷云进行了模拟试验。结果表明，消散电流对雷云净起电电流的削减将减缓雷云电压的上升速度并减低雷云电压数值，从而实现消雷。雷云参数及其与消雷器的相对位置对消雷效果也有很大影响。

Lightning eliminators have been running very well in Yunnan province. To explain the lightning eliminating mechanism simulation tests were carried out which reveal that the dissipating current will cut down the net charging current inside a thundercloud, slow down the rising speed of voltage and reduce the cloud voltage value so as to prevent from lightning strokes. Both the parameters of thundercloud and the relative locations between the cloud and eliminator will largely influence the effects of lightning elimination.
