陕京三线交流干扰防护新技术应用与优化总结

Application and Optimization of New AC Interference Protection Technology in 3^rd Shaanxi - Beijing Gas Pipeline

陕京三线输气管道工程对受交流干扰的区段采用了集中接地、故障屏蔽、固态去耦合器接地等交流干扰防护新技术，本文根据现场对干扰程度调查与测试、防护效果评价检测、固态去耦合器运行参数、持续干扰防护接地点优化调整与测试等工作所获得的详细的实际数据，侧重对固态去耦合器接地方式新技术的应用情况，以及防护点的优化进行了总结，对埋地钢质管道交流干扰防护工程的设计、施工及运行测试具有指导作用。

For those sections of 3^rd Shaanxi - Beijing Gas Pipeline effected by AC interference, a number of new AC interference protection technology are applied such as an integrated grounding, shiel- ding of faults, and solid decoupler grounding. Based upon the detailed actual data obtained on site during the investigation and testing of the interference degree, the evaluation and detection of protection effect, the operation parameters of the solid decoupler, and the optimization adjustment and testing of those con- tinuous interference protection grounding points, the paper focuses on the summarization of the application of new solid decoupler grounding method and the optimization guide in the design, construction, operation and testing of AC steel pipeline of the protection points. It is useful as a interference protection projects of buried
