摘要
介绍试片断电法的原理，采用两块不同规格的试片进行实验，对CIPS检测仪延迟时间的选取进行分析，得出最佳的延迟时间为100—250ms，所测得的试片断电电位达到稳定状态，可以反映埋地钢质管道真实有效的阴极保护情况。
The principle of test block power in- terruption method is introduced. Two test blocks with different specifications are tested, and the selection of delay time for CIPS detector is analyzed. The optimal delay time is 100 to 250 ms. The measured potential for power interruption of test blocks reaches a stable state, which can reflect the real and effective state of cathodic protection for buried steel pipeline.
