一种混合型杂散电流排除方法
A hybrid method for eliminating stray current interference
摘要
Abstract
In the operation and management of long-distance transmission pipelines,two independent stray current draining facilities are usually required to eliminate the impact of DC interference and AC interference on the pipeline respectively,as the two types of interference on the pipeline cannot be eliminated by one set of current draining facilities simultaneously.In order to solve this problem,a comprehensive analysis of the interference impact of a gas transmission pipeline was carried out,and a hybrid stray current elimination method was proposed,which used AC and DC dual-purpose stray current drain unit + special discharge bed to form a set of hybrid discharge facilities,so as to eliminate the AC interference and DC interference on the pipeline at the same time,and ensure the safe operation of the pipeline.The system has passed field trials and tests and achieved remarkable results.The hybrid stray current elimination method can eliminate two different stray currents at the same time,thereby reduces the land acquisition area and minimizes environmental impact of the project.关键词
