摘　　要：为了满足e级污秽等级下750 k V屋外配电装置布置设计的最小安全净距要求,分析了e级污秽等级对绝缘子串选择和构架选型的影响,提出了适用于e级污区的750 k V屋外配电装置构架宽度和挂线点高度的选型方案,该方案满足e级污秽等级下750 k V屋外配电装置布置设计最小安全净距要求。To satisfy the minimum safety distance requirements of 750 k V outdoor switchgear layout design under the e pollution level. The influences of e pollution level on insulator string selection and frame selection are analyzed. The selection scheme about the hang line point height and width of frame for 750 kV outdoor switchgear is proposed, which is applicable to e pollution zone. The scheme satisfies the minimum safety distance requirements of 750 kV outdoor switchgear layout design under the e pollution level.
