摘要
在接触网系统中,衡量弓网关系的性能指标有接触线高度、拉出值、坡度、硬点和弹性等。而在诸多接触网技术性能指标中,链形悬挂双接触线的等高度是否符合标准将直接关系到弓网间的平滑过渡和受流质量。
In the catenary system, the performance indexes of pantograph -catenary relation include contact line height, pull out value, slope, hard point and elasticity, etc. Among the technical performance indexes of catenary, whether the equal height of the double contact line of the chain suspension meets the standard will directly affect the smooth transition and the quality of the current receiving between the pantograph and the catenary.
