一个或两个补偿电容故障条件下分路电流的建模与仿真
Modeling andSimulation of Shunt Current under the circumstances of one or two Compensation Capacitors Failure
Abstract
轨道电路是由钢轨线路和钢轨绝缘构成的电路，用于自动、连续检测某段线路是否被机车车辆占用，补偿电容作为轨道电路的重要组成设备，可以有效的改善轨道电路的传输特性，延长其传输距离，对于保障列车安全运行起到了不可替代的作用，补偿电容失效将直接影响轨道电路对信号的传输，甚至危及行车安全，制约正常的运输效率。单个补偿电容故障，一般只会造成轨道电路接受端的接受电压些许下降，并不会造成红轨。正因为如此，补偿电容故障具有其他显性故障没有的隐蔽性，另外，对于已经失效的补偿电容故障查找，传统的去线路上依次检查的查找方法费时费力，这种效率低下的故障查找方法显然不能满足我国铁路快速发展的需要。 根据文献调查，对轨道电... Track circuit is a circuit comprisedby the rail line and rail insulation. It is used to check the integrity of train and its occupation automatically and continuously .As an important component of track circuit equipment, The compensation capacitorcan effectively improve the transmission characteristics of the track circuit and extend its transmission distance. The compensation capacitor played an...
