GIS中导电颗粒与电极碰撞系数的测量与分析
Measurement and Analysis of the Coefficient of Restitution Between Conducting Particles and Electrodes in GIS
摘要
Abstract
In GIS,the motion of conducting particles is random but the randomness depends on the coefficient of restitution and angle of incidence when approaching the coaxial conductors.In order to obtain the coefficient of restitution between charged particles and electrodes accurately in GIS and guide the research of the moving characteristics of charged conducting particles,a measuring platform is built for the coefficient of restitution between the charged conducting particles and a copper plate based on the principle of kinematics.I have studied separately the effects of radius of conducting particles,colliding speed,coating material and coating thickness on the coefficient of restitution by single-factor experiment and the regression analysis has also been carried out.The results show that the radius of particles has no significant effects on the coefficient of restitution;with the increase of colliding velocity,the normal coefficient of restitution will decrease in a power function with a negative exponent,and the tangential coefficient of restitution will decrease at first and then increase;coating of silicon rubber and epoxy resin can increase the normal coefficient of restitution and with the increase of coating thickness,the coefficient of restitution basically all shows a law of gradually increasing firstly and finally tending to be saturated.关键词
