摘　　要：通过分析现场试验发生的重击穿与NSDD所产生的过电压对电容器和真空断路器断口过电压影响的实际情况,对照国标GB/T 1984—2014对真空断路器开合电容器组试验要求、试验参数选择、判据条件,探讨一些试验要求和试验参数选择的疑难点,提供符合现场实际情况的参数选择,为用户解读试验报告中试验参数和试验结果判据是否符合应用要求提供借鉴。In this paper,the difficult points on test requirement and test parameter selection are discussed on the basis of the analysis of the actual influence on the over voltage across open contacts of capacitor and the vacuum breaker due to the re-strike at the site test and the over voltage by NSDD and with reference of the test requirement of vacuum circuit breaker in switching the capacitor specified in GB/T 1984,test parameter selection and criteria condition,the parameter selection complying with actual situation at site is provided so to provide the clients with reference in understanding whether the test parameters and test results criteria the test report are in line with the application requirements.
