摘　　要：由于对绝缘子污闪特性的研究主要是针对单串绝缘子,而对于多串并联、V形串等特殊安装形式绝缘子的污闪电压特性研究得并不多。文章结合线路运行中绝缘子污闪故障的特点,对单串、双串并行和V形串绝缘子的污闪电压特性进行了试验研究。通过两种普通型绝缘子(XP-70和XLP-160)得到了不同安装结构对绝缘子污闪电压的影响规律。研究结果可为输电线路绝缘设计借鉴。Most of the existing references of insulator＇s pollution flashover characteristics are mainly related to single insulator string, and there are few references related to the pollution flashover characteristics of special installation forms of insulator strings, such as parallel multi-strings, strings connected in V-shape, etc. Combining with the features of insulator pollution flashover faults occurred in the operation of transmission lines, the experimental investigation of pollution flashover voltage characteristics for single string, parallel double strings and strings connected in V-shape are carried out. Taking two conventional types of insulators for example, i.e., the porcelain insulator XP-70 and glass insulator XLP-160, the influence of. installation forms on pollution flashover characteristics for above-mentioned installation forms of insulator strings under three kinds of pollution levels are researched. The obtained results could be available for reference in the insulation design of overhead transmission line.
