京九南线电力线路接地网存在的问题研究

Study on the Existing Problems of the Grounding Grid of the Power Line of Beijing Jiulong South Line

铁路电力系统的供电安全在整个铁路系统中占有重要地位,其直接影响铁路系统的运行。特别是近年来随着铁路电气化高速发展,大批新设备在铁路沿线得到广泛使用,对接地网的要求越来越高,在常规电力系统运维的基础上,需要一线技术人员采取更为精准和有效的策略,并结合日常运维工作的经验才能够更好地完成铁路电力系统线路接地网的维护工作,确保铁路电力系统工作的安全性和稳固性。笔者以自己在京九南线一线工作的经验,分析了铁路电力接地网存在的问题,并提出相应的改进建议。

Power supply security of railway power system plays an important role in the whole railway system,which directly affects the operation of the railway system.Especially in recent years,with the rapid development of railway electrification,a large number of new equipment are widely used along the railway,and the requirements for connect⁃ing to the ground network are becoming higher and higher.On the basis of conventional power system operation and maintenance,it is necessary for front-line technicians to take more accurate and effective strategies,and combine the experience of daily operation and maintenance work to better complete the maintenance of the railway power system line ground network Work to ensure the safety and stability of railway power system.Based on the experience of work⁃ing in the south line of Beijing Kowloon Railway,the author analyzed the existing problems of the railway power grounding network,and put forward corresponding improvement suggestions.
