强制电流阴极保护系统主要面临核心部件故障和阴极保护系统性能欠缺等问题。 为保证阴极保护系统正常稳定运行，提升阴极保护系统管理效率，通过对上述阴极保护系统常见故障及原因进行分析总结，结合恒电位仪输出参数的监测，为后续阴极保护系统故障自动诊断及现场快速诊断排查提供参考。

The impressed current cathodic protection system primarily faces issues such as core component failures and inadequate system performance.To ensure the normal and stable operation of the cathodic protection system and improve its management efficiency， an analysis and summary of common faults and their causes in the system were conducted.By monitoring the output parameters using a potentiostat， this study provided a reference for the subsequent automatic fault diagnosis and on-site rapid troubleshooting of the cathodic protection system.
