摘　　要：建立了非线性防晕材料的高精度测试系统,对测试过程中的电压、压力、时间和湿度等影响因素进行了试验分析及研究,得到了获取准确试验数据的方法。通过对试验数据进行线性拟合,提取了防晕设计所需的参数,进行了防晕结构的设计,并进一步通过仿真线棒的耐压试验和理论计算,对测试方法的正确性进行了验证。A high-precision test system of nonlinear anti-corona material was established. The effects of voltage, pressure, time and humidity in the test process on the test results were analyzed, and the method that can gain accurate test results was obtained. By linear fitting the experimental data, the anti-corona design parameters were extracted and the anti-corona structure was designed. The method was validated by the voltage withstand test of simulating stator bar and theoretical calculation.
