Inspection and Evaluation of Solid State Decoupler in AC Interference Mitigation
摘 要
某原油输送管道在交流干扰严重区段采用了固态去耦合器接地的交流干扰缓解措施。通过现场干扰程度调查与测试、防护效果检测评价、固态去耦合器运行参数测试等工作, 获得了详细的现场数据, 对固态去耦合器产品的性能与应用效果进行了评价总结, 为埋地钢管交流干扰缓解工程的固态去耦合器的选型与应用提供参考。
Abstract
AC interference mitigation of a crude oil pipeline was applied using DC decoupler within grounding system. Inspection results of on-site survey have been analyzed to evaluate the performance of AC mitigation system and decoupler. The parameters involved in the inspection include AC interference magnitude before and after mitigation, operation data of DC decoupler, etc. This study could be helpful for design and application of DC decoupler in AC mitigation.
