某长输管道强制电流阴极保护系统故障分析及排除措施

摘要

For the abnormal potentiostat output of Impressed Current Cathodic Proteetion（ICCP） in a long-distance pipeline, the ICCP system failure was analyzed and problems were found finally, and then some measures were taken to restore the CP system. And taking it as an example, the frequent failure analysis and treatment measures in ICCP system of long-distance pipeline are introduced briefly.%针对某长输管道强制电流阴极保护系统出现的恒电位仪输出异常的情况，对阴保系统故障进行了分析排查，并采取排除措施使阴保系统恢复正常运行。以此为例，简述了长输管道阴极保护系统常出现的故障及排除措施。
