| Abstract: | The influence to 25Hz phase sensitive track circuit caused by 50Hz dynamic traction current is discussed.After setting up the mathematic model of 25Hz phase sensitive receiving circuit,the transient of phase sensitive receiving circuit is analysed by means of computer simulation,and a discussion on the relationship between the phase of dynamic traction current and the transient of phase sensitive rceiving cixcuit is given. |
