针对新大管道受到来自轻轨铁路及交流高压线路等杂散电流的干扰可能导致的腐蚀穿孔问题,进行了研究分析,并对其主要干扰源相关数据进行了测试分析,采取了有针对性的排流防护措施。实践表明,管道保护电位达到正常值,直流排流保护效果满足相关标准要求。
Aiming at the problem of corrosion and perforation caused by the interference of new sturdy pipes from stray current such as light-rail railway and AC high-voltage lines, the paper analyzes and analyzes the data of the main sources of interference, Flow protection measures. Practice shows that the pipeline protection potential to reach the normal value, DC discharge protection to meet the relevant standards.
