电气化铁路接触网可靠性及维修探析

Discussion on Reliability and Maintenance of Electrified Railway Catenary

电气化铁路接触网作为长年累月裸露在外的露天设备,其本身的零件与结构必定会受到自然条件变化的直接影响,再加上受电弓沿接触线高速摩擦滑行,就会让接触网处于摩擦、振动、电热等物理变化影响之中,导致接触网技术参数很容易发生变化。为了能够满足电力机车安全行驶的要求,就应该对接触网的可靠性进行分析,并且做好其相应的维修,这样才能确保电气化铁路接触网能够满足铁路运营的要求。因此,文章在分析电气化铁路接触网基本性征的前提下,通过对接触网系统维修计划的实际分析,希望可以通过可靠性和维修的探讨,为电子化铁路的发展奠定良好的基础条件。

The electrified railway catenary as long exposed outdoor equipment, its components and structure must be affected by changes of natural conditions, coupled with the pantograph high-speed friction sliding along the contact line, can let a catenary in friction, vibration, electric heat physical changes, such as result in changes of catenary parameters easily.In order to meet the requirements of electric locomotive safe operation, the reliability of the contact network should be analyzed and its corresponding maintenance should be done, so as to ensure that the electrified railway contact network can meet the requirements of railway operation.Therefore, based on the analysis of the basic characteristics of electrified railway catenary system, through the actual analysis of the catenary system maintenance plan, this paper hoped that the reliability and mainte- nance can be discussed to lay a good foundation for the development of electronic railway.
