土体雷电冲击实验装置设计与特性分析

Design and Characteristic Analysis of Experimental Device for Lightning Shock of Soil

结合雷电场作用下土地的击穿机理和土体中接地与接地电阻理论,设计土地雷电冲击特性实验方案,利用雷电冲击电压电流发生器和设计的试验装置完成各因素影响下的雷电冲击试验。通过改变土地含水量和含盐量,研究不同条件下土体的冲击特性。

Combining with the mechanism of land breakdown and the grounding and grounding resistance theory of soil under the action of lightning field,the experimental scheme of mine lightning impulse characteristic is designed.The lightning impulse voltage and current generator and the designed test device are used to complete the lightning impulse test.The impact characteristics of soil under different conditions were studied by changing the water content and salt content of the land.
