±800 kV宾金线浙江段带电绝缘子积污特性及离子成分分析
|
摘要
为获得特高压直流电场作用下的盘型悬式绝缘子带电积污特性及其污秽离子成分特征,在±800 kV宾金线浙江段选取3基典型环境杆塔,同塔设置高电位污秽测试串、地电位污秽测试串,积污1年、2年后开展等值盐密、等值灰密测试,对绝缘子积污带电系数、电场对污秽增长的影响进行了分析,并对积污2年时绝缘子上、下表面的离子成分进行了研究。结果显示,绝缘子积污2年时等值盐密、等值灰密带电系数分别为1. 54、1. 36,与单年积污结果相近;高电位绝缘子串的污秽增长率与地电位串接近;绝缘子上、下表面的污秽离子主成分一致,但主成分离子比例存在差异,下表面Ca~(2+)占比显著高于上表面。
In order to investigate the contamination deposit characteristics and pollution ion components of energized cap and pin insulator on UHVDC transmission line,three points with typical environment were chosen as the test tower. On each tower,energized insulators and de-energized insulators were set for contamination test. The equivalent salt deposit density( ESDD) and non-soluble deposit density( NSDD)of test insulators were measured after one year and two year contamination,based on which the energized coefficient and the effect of electrical field on pollution accumulation were analyzed,and the pollution ion components of top and bottom of test insulators after two year contamination were grasped. It can be concluded that the energized coefficient of ESDD and NSDD are 1. 54 and 1. 36 of the two year polluted insulators,which are close to the results of one year polluted sample. The pollution increase rate of energized insulators is proximate to the de-energized samples. The main ion species is the same between top and bottom of insulators,while differences exist in the ion proportion that the ratio of Ca~(2+)of bottom insulators is dramatically larger than that of top insulators.
