- 针对西气东输管道线路阀室发生多次GOV阀误关断问题，从防雷抗干扰方面进行分析并提出改造方案。阀室防雷电干扰改造项目完成后，GOV阀误关断事件大幅度下降，从而有效提高了管道运行的安全性和经济性。
In view of the problem that GOV valves have wrong shut off for many times in the West to East Gas Pipeline,the analysis from the aspect of lightning-proof and anti-jamming was performed and the modification scheme was put forward.After the modification project on lightning-proof and anti-jamming of valve chamber was completed,the events of wrong GOV valve shutoff were dropped substantially.The safety and economics of the pipeline operation were effectively improved.2013,4(4): 55-57 收稿日期：2012-6-19DOI：10.3969/j.issn.1001-2206.2013.04.017作者简介：端木君(1981-),男，上海人，工程师，2007年毕业于上海海事大学，硕士，主要从事电气管理工作。
