摘要
从立体几何和平面几何原理角度,对利用滚球法确定单支、双支避雷针保护范围进行了说明与分析。介绍了常州新一代天气雷达站接闪器的设计过程。经分析、计算,确定安装3支15.8m等高避雷针和1.5m高不锈钢护栏作为混合接闪器,以保证天气雷达站安全、有效。
From the angle of solid geometry and plane geometry,the method that use rolling ball method to determine the protection scale of single and double lightning rod was described and analyzed.The design process of Changzhou new flash grounding device of radar station was introduced.After analysis and calculation,it was determined that setting three 15.8 meter high lightning rod and 1.5 meter high stainless steel guardrail as mixed flash grounding device to guarantee the safety,effectiveness of weather radar sta...
