摘要
近年来,随着对动态直流杂散电流干扰研究的不断深入,如何准确地测试埋地管道在动态直流杂散电流干扰下的阴极保护数据并评价其有效性已成为阴极保护工程师亟待解决的问题。本文通过比较极化试片法和GPS同步中断法采集的两种阴极保护数据结果,得到了简化日常测试过程和优化测试结果的方法,给管道阴极保护日常维护减负、专业化测试调查提供了参考建议。
In recent years,with the continuous research on dynamic DC stray current interference,we recognized how to accurately test the cathodic protection data of buried pipeline under dynamic DC stray current interference and evaluate the effectiveness has become an urgent problem that need to be solved for cathodic protection engineers.After comparing the data collected by coupon polarization test and GPS synchronous interruption test,we obtained a method that could simplify the daily test process and optimize test result.In this paper,we discussed some reference suggestion for pipeline daily cathodic protection maintenance and comprehensive investigation tests.
