摘要: 航天器充放电效应地面模拟试验中需要测量的一个重要参数是介质的充电电位。文章基于介质充电电位的非接触式转接测量技术,分析了测量中引起误差的各个因素,讨论了减小测量误差和提高转接测量分辨率的方法,并进行试验验证。据此设计了一套介质电位非接触式转接测量系统,其测量分辨率达到10 V以下,且由电荷泄漏引起的测量误差< 1%,能够满足航天器介质充电电位的测量要求。Abstract: The dielectric charging potential is one of the important parameters to be measured in the charging and discharging effect simulation test. A non-contact transferred measurement method is presented, the influencing factors on the measurement errors are analyzed, the methods for improving the transferred measurement resolution are proposed, and a non-contact measurement system with a transfer mechanism is designed. The validation test results show that the resolution of the dielectric charging voltage is less than 10 V, and the error caused by the charge leakage is less than 1%. The system can meet the requirements of the spacecraft dielectric charging potential measurement.
