Optimization of Dielectric Material Surface Charge Measurement and Impact of Plasma Treatment on Their Surface Electrical Characteristics
摘要
Abstract
The electrical performances of dielectric materials are determined by their charge decay property,which will significantly affect their polarity,anti-static property,and flashover voltage.It is of great significance to measure the surface charge distribution accurately.On the basis of self-built surface potential measurement system,we studied the effects of voltage amplitude,charging time,the presence or absence of grid mesh and humidity on the epoxy resin surface potential distribution.The optimal measurement condition was obtained.In addition,the discharge parameters of dielectric barrier discharge (DBD) plasma were optimized for epoxy resin modification.The surface potential decay property of epoxy resin with different plasma treatment time was studied.The results showed that the highest voltage potential increased with applied voltage,but saturated afterwards.The duration of applied voltage slightly affected the surface potential,while it increased with increased humidity.The grid mesh suppressed the surface potential decay rate.Further results showed that after DBD plasma treatment,the surface potential decay rate of epoxy resin increased.The optimal surface potential value was obtained after 180 s treatment.The results provide a solid reference for surface potential measurement and an effective modification method for accelerating surface potential decay.关键词
