【摘要】 介绍广州地区５００ｋＶ线路绝缘子串分布电压的现场实测，通过分析，得出如下规律：无论单串或双串，中相绝缘子串的电压分布总比边相串更不均匀；在相同条件下，绝缘子串的元件数越多，电压分布越不均匀；中相Ｖ型串与垂直串的电压分布规律非常接近；酒杯塔与拉Ｖ塔的塔型对边相绝缘子串的电压分布规律无明显影响。更多还原

【Abstract】 The paper describes the field measurement of voltage distribution on insulator strings on insulator strings on 500 kV transmission lines in Guangzhou area. By analysis, the regularities were obtained as follows: the voltage distribution on insulator string of the middle-phase, whether single or double strings are more uniform than that of side-phase under the same conditions, the more units of insulator strings the more uniform of voltage distribution on middle-phase. The regularity of voltage distribution are very similar between V-sin fig and vertical string. On side-phases, the voltage distribution of insulator string is not affected significantly by tower types.更多还原
