摘　　要：电力电缆是电力系统的重要组成部分,电缆运行是否可靠直接影响电力系统的供电可靠性。而电缆附件上电应力集中问题严重影响电缆的安全可靠运行,亟待解决。针对这一问题,以交联聚乙烯绝缘电缆结构为基础,分析电缆附件上的电场分布情况,重点研究电应力的控制方法,并提出一种满足高电压等级电缆需求的电应力控制新途径。Power cable is an important part of the power system, and its running reliably directly affects the reliability of the power system supply. However, the problems of electrical stress concentration in cable accessories seriously affect the safe and reliable operation of the cable, which is to be solved urgently. In terms of this problem, electric field distribution in cable accessories has been analyzed on the basis of the structure of XLPE insulated cable, and stress-controlling methods has been studied mainly. Moreover, a kind of new way of stress-controlling, which can meet the demand of high voltage electric cable, has been put forward.
