摘要

依据电磁场基本定律和罐底阴极保护系统的几何特征推导深井阳极电场在罐底外侧的电位分布.根据电场叠加原理,综合考虑阳极电场和阴极电场的作用,研究了单侧深井阳极保护下罐底外侧的阴极保护电位分布,并将计算结果与实测数据作对比,吻合较好.

Abstract

Potential distributions of deep well anodic electric field on external tank bottom were derived according to the basic law of electromagnetic field and the geometry characteristics of cathodic protection system.Making use of electric field superposition principle,considering the action of anodic and cathodic electric fields,the potential distributions on external tank bottom under the protection of deep well anode were studied.The calculated results were compared and agred well with the measured data.
