摘　　要：通过绝缘管型引雷针与普通导体避雷针的雷击模拟实验对比,得到其一系列优良特性。运用模拟电荷法,对绝缘管型引雷针与普通导体避雷针在雷云电场下所形成的电场分4种情况进行了计算结果的比较,得出绝缘管型引雷针所形成的空间场强大于普通导体避雷针所形成的空间场强,其引雷能力强于普通导体避雷针。The insulation-tube arrester has a series of characters which are better than the common lightning arrester through lightning stroke experiments. This paper compares calculation results under four different electric fields that formed by common lighten arrester and insulation-tube arrester with method of simulated electric charge. It is shown that the strength of the space electric field formed by insulation-tube arrester is larger than common arrester's. The ability of inducing lighten is better than the common arrester's.
