摘　　要：采用电化学噪声测试技术对变电站接地网土壤腐蚀状况进行实时在线监测。结果表明:接地网环境发生改变时,对土壤腐蚀特性有较大影响,接地网腐蚀状态变化较大。电化学噪声监测系统对土壤腐蚀环境的变化反应灵敏,能够进行实时准确的监控预警,可用于变电站基建勘察以及运行维护阶段的腐蚀监控。The substation grounding grid corrosion status was in real-time and online monitored using electrochemical noise technology.The results show that the change of grounding grid environment had a great effect on soil corrosion characteristics and led to great changes of the grounding grid corrosion.Electrochemical noise monitoring system is sensitive to the changes of environment and may implement real-time accurate monitoring and warning,and thus it can be used for corrosion monitoring in the stages of substation construction survey and operation.
