摘要:
统计了广州地区110 kV氧化锌避雷器停电试验的数据,运用统计学方法获得了避雷器的直流参考电压和泄漏电流的分布特性; 在此基础上研究了这两个参量与外界温度、湿度和运行年限的规律关系,根据拟合直线斜率求出了环境温度和湿度的换算公式。分析了3个因素对参考电压和泄漏电流的影响程度大小,由增量方程的斜率可知,对参考电压和泄漏电流影响最大的因素是运行年限,其次是环境温度,环境湿度对上述两个参量的影响程度最小。从而可以根据参考电压和泄漏电流的值对避雷器的状态做出更加准确的判断。
Abstract:
The data of the off-line detection of 110 kV Zinc Oxide arresters in Guangzhou area were collected, and the distribution characteristics of DC reference voltage and leakage current were obtained by using the statistical method. On this basis, the relationship between these two parameters and the external temperature, humidity and operating time is studied, and the conversion formula of ambient temperature and humidity is calculated based on the slope of the fitted line. The influence of three factors on the reference voltage and leakage current is analyzed. The slope of the incremental equation shows that the factor that has the greatest influence on the reference voltage and leakage current is the operating years, followed by the ambient temperature, and the ambient humidity has the least influence on the above two parameters. Therefore, a more accurate determination of the state of the arrester can be made based on the value of the reference voltage and the leakage current.
