摘要
为保障埋地钢质管道的安全运行,针对区域阴极保护对站外管道的直流阴极干扰问题进行了专项测试与研究。通过通断电位测试确定了对外部管道造成干扰的区域阴极保护电源,通过站外管道的电位测试明确了受干扰段的长度。针对区域阴极保护的特点分析了造成外管道阴极干扰的原因。
In order to ensure the safe operation of buried steel pipelines,special tests and studies were carried out on the cathodic DC interference of regional cathodic protection to pipelines outside the station.Through the on-off potential test,the regional cathodic protection DC power that interferes with the external pipeline is determined,and the length of the affected section is determined through potential survey of the pipeline outside the station.According to the characteristics of cathodic protection in confined area,the causes of external pipeline cathodic interference are analyzed.
