摘　　要：对浙江省西部２２０ｋＶ新安江一杭州输电线路Ｉ回路在２７ａ中用磁钢棒实测到的全部雷击数据（７１６次）作了数据统计分析、得出该线路的雷电流幅值累积概率分布公式及其它雷电参数。它反映了浙江省部分地区的雷电活动规律，其计算公式已被电力行业标准ＤＬ／Ｔ６２０－１９９７《交流电气装置的过电压保护和绝缘配合》采用。The statistical analysis on lightning stroke data(716 strokes)measured by magnetic steel bars for 27 years on Xin'anjiang-Hangzhou 220 kV line in Zhejiang Province has obtained the lightning current amplitude accumulative probabilistic distribution formula and other lightning parameters. It reflects the rule of lightning activities in some areas in Zhejiang Province.The calculation formula has been employed and put into the power industry standards DL/T620-1997, the'Over Voltage Protection and insulation Coordination of AC Electrical Apparatus'.
