摘　　要：阴极保护电位检测时候常用万用表检测管道的保护电位,但是当管道有杂散电流干扰存在时,管道电位会波动变化,需要进行连续24、48 h或更长时间的数据监测,既需要监测管道的通电位、管道的断电位,还需要监测管道交流电压、交流电流密度。这种状况下如果使用万用表就存在很大局限,要使用类似uDL2这样一款具有多功能的数据记录仪。文章结合具体案例阐述了数据记录仪uDL2在管道杂散电流干扰监测方面的实际应用,为解决该类问题提供了实践经验。A multimeter is commonly used to detect the protective potential of pipelines during cathodic protection potential detection.However,when there is stray current interference in the pipeline,the pipeline potential will fluctuate and change,requiring continuous data monitoring for 24 hours,48 hours or longer.It is necessary to monitor both the on potential and off potential of the pipeline,as well as the AC voltage and AC current density of the pipeline.In this situation,the use of a multimeter has significant limitations and requires the use of a multifunctional data recorder such as uDL2.This paer combines specific cases to illustrate the practical application of the data recorder uDL2 in monitoring stray current interference in pipelines,providing practical experience for solving such problems.
