复杂结构沿面闪络产生发展阶段模拟研究
Simulation study of initialization and development stages of surface flashover in 3D complex structure
摘要
Abstract
The electric field emission and thermal emission around the junction of triple point and the secondary electron emission are believed to play a major role in the initialization and the development stages of the surface flashover.We have extend-ed OPAL,a parallel framework for charged particle optics in accelerator structures and beam lines,with the necessary particle-boundary collision test model,field emission model as well as secondary emission models to simulate the initialization and develop-ment of surface flashover in an X-pinch load case with complex geometry.The discharge experiment shows that the silicon oil coa-ted case has a stronger return current than the not-coated case.Accordingly,possible way of flashover suppression is discussed.关键词
