摘要
为研究百纳秒脉冲下两种典型的绝缘材料(尼龙和有机玻璃)在气体中的沿面闪络特性,设计了百纳秒脉冲沿面闪络实验平台。通过实验研究了绝缘材料的闪络电压随气体气压、闪络距离、等物理因素的变化规律,实验表明:闪络电压随着气压的增加而增加,但是闪络场强随着闪络间距的增加而降低;在相同条件下,有机玻璃的闪络电压比尼龙高。同时通过沿面闪络实验,得到在百纳秒脉冲下不同气压、不同闪络间距的闪络电压值。
Abstract
In order to research the surface flashover characteristics of two typical insulating materials (nylon and synthetic glass) under hundred-nanosecond pulse in nitrogen gas, experimental device of surface flashover under hundred-nanosecond pulse was designed. The variation laws of the flashover voltage of the insulating material with air pressure and flashover distance have been researched via experimentation. The experimental results showed that the flashover voltage increased with the increasing of the air pressure. However, the flashover electric field intensity decreased with the increasing of the distance. In the same condition, the flashover voltage of PMMA is higher than that of nylon. The flashover voltage of the materials with different gas pressure and distance under hundred-nanosecond pulse were obtained via the surface flashover experiment.
