定量分析了轨道电路固有衰耗和轨道电路一次参数之间的关系,推导出了轨道电路固有衰耗的计算公式,并利用这些公式分析了无砟轨道对轨道电路固有衰耗的影响.研究表明:轨道电路的最小固有衰耗值随着钢轨电阻的增加而增加;和有砟轨道相比,无砟轨道电路的最优补偿电容减小了,而最小固有衰耗却增加了;改变无砟轨道的结构设计是改善无砟轨道电路传输特性的根本措施.
The relationship between the inherent loss of the track circuit and the primary parameter of the track circuit is quantitatively analyzed and the calculation formula of the inherent loss of the track circuit is deduced.The influence of the ballastless track on the inherent loss of the track circuit is analyzed. : The minimum inherent loss value of the rail circuit increases with the increase of the rail resistance. The optimal compensation capacitance of the ballastless rail circuit decreases, while the minimum inherent loss increases compared to that of the ballasted rail. The structural design of the track is the fundamental measure to improve the transmission characteristics of the ballastless track circuit.
