多间隙气体放电管研究及其应用
Study and Application of the Multi-Gap for Gas Discharge
摘要
Abstract
For solving the problems of high breakdown voltage and power-flow current in the gas discharge tube applied in lightning protection,a multi-gap model for gas discharge was constructed based on Townsend theory and Parson's law.Moreover,the breakdown voltage of the proposed model is β (β< 1) times the breakdown voltage of the ordinary single gas discharge tube.The lighting current impacting experiment was carried on the multi-gap discharge tube.The conclusions can be drawn as follows.The breakdown voltage of the proposed model is 5 times less than that of the traditional gas discharge tube,and the response time can be shorten to 200ns.Furthermore,the rising rate of residual voltage can be reduced to 0.3kV.μs-1.Besides,the multi-gap gas discharge model can reduce or even remove the power-flow current within a certain range of lightning current.关键词
