Discussion on the Evaluation and Protection of Stray Current Interference in Long-Distance Oil and Gas Pipeline

论文简述了油气长输管道阴极保护系统的各项控制要点,分别阐述了交流干扰和直流干扰对检测效果的影响及相应的防护措施,旨在通过分析交直流干扰的形式与危害性,找出有效的抗干扰检测与评价手段,为保障油气长输管道稳定运行提供参考。

The paper briefly describes the control points of cathodic protection system for long distance oil and gas pipeline, separately expounds the influence of AC interference and DC interference on the detection effect and the corresponding protective measures. The purpose of analyzing the form and harmfulness of AC-DC interference is to find out effective anti-interference detection and evaluation means, and provide reference for ensuringthe stable operation of long-distance oil and gas pipeline.
