摘要
文中利用显著性差异的分析手段对浙江电网在运的上海MWB公司220 k V COT型套管的介损数据进行统计分析,验证了该类套管介损符合正态分布规律,根据统计离群值的要求确定了样本数据的显著性差异条件,提出了在运的该类套管的介损阈值。
Based on significance difference analysis method, this paper statistically analyzes the dielectric loss data of Shanghai MWB＇s 220 k V COT bushings. It indicates that the data consist with normal distribution and the condition of significance difference is determined based on the statistical scatter value requirement. Finally, the threshold of the dielectric loss of these bushing is presented.
