摘　　要：通过对500 kV大房二回线路2000-2003年连续4年盐密测量结果的统计分析,结合华北电网其他供电公司及保定供电公司超高压工区多年的盐密测量经验,阐述了超高压输电线路绝缘子积污量与积污时间的关系,找出了盐密测量和输电线路绝缘子的防污清扫的最佳季节,同时探讨了绝缘子表面污秽分布情况对盐密值的影响。Based on the statistical analysis on the salty dense measurement results of 500 kV Dafang lines from 2000 years to 2003 years, combined with the experiences of other units of the North China electrical network and the Baoding electric power company ultrahigh voltage work area, the article elaborates the relations between accumulated filth quantity and the accumulated filth time of the ultrahigh voltage transmission line insulator, and then discovers the best season which the salty dense survey and the transmission line insulator antifouling sweeps clear. Meanwhile, carries on the discussion of the insulator surface contamination distribution situation and the salty dense value influence.
