摘要
本文介绍外加电流保护技术应用于长输埋地钢质管道,由于定向穿越段管道保护电流损失严重,且部分山体段土壤电阻率偏高,保护电流流向管道较少,导致部分管道难以得到保护。
Used in this paper,the impressed current protection technology in buried steel pipeline,due to the directional cross section of the pipeline protection current loss is serious,and part of the mountain soil resistivity on the high side,less protection current flow to the pipe,lead to part of the pipeline to be protected.
