接触网质量评价方法与评价体系
|
摘要
目前世界各国普遍采用对接触网检测参数进行幅值管理的方式,以发现设备的局部缺陷并消除安全隐患。为克服该方法无法对接触网整体质量进行量化描述的不足,提出综合考虑影响接触网静态质量与弓网运行质量的多个参数,对接触网质量进行区段评价的方法。接触网检测参数幅值管理与区段质量评价2种方法共同构成完整的接触网质量评价体系。经大量检测数据验证,将2种方法相结合,既可找出局部缺陷,又可准确判断每段接触网的质量状态,对基础设施管理合理制定维修策略、分配维修资源具有指导意义。
At present,various countries in the world widely adopt amplitude management for overhead contact line system(OCS) detecting parameter,to find out partial defect and eliminate security risks.To overcome the shortcoming of the method which cannot implement quantitative description of the overall quality of OCS,the paper proposes several parameters affecting static quality of OCS and running quality of pantograph and contact wire,as well as the section assessment of OCS quality.The quality assessment system consists of two methods,namely,the amplitude management of OCS detecting parameter and section quality assessment.Verified by a mass of test data,the combination of the two methods can not only find out partial defect,but also accurately estimate the quality situation of each OCS,providing guidance for infrastructure management to make reasonable maintenance strategy and allocate maintenance resources.
