| Split phase power supply is the main mode of power supply of electrified railwayinChina,the electric locomotive auto-passing neutral-section device technique has been an important part of the locomotive department to explore the smooth operation.ShuoHuang Railway as heavy load electrified railway,Ac drive electric locomotive and DC electric locomotive are widely used in ShuoHuang Railway.Electric locomotive auto-passing neutral-section technology is an important technology to improve the degree of locomotive automation,in ShuoHuang Railway is also widely used.On the basis of the application of auto-passing neutral-section in ShuoHuang Railway,the main problem of this study is how to use the information of the locomotive and the corresponding intelligent algorithm to achieve the control of the locomotive automatic passing phase separation.This paper studies the design principle of auto-passing neutral-section device ShenHua eight axis AC drive electric locomotive based on ShuoHuang line,and combined with the characteristics of shuohuang line and the application of auto-passing neutral-section,this paper forms a set of improved hardware and software design,and the improved device is verified by experiments.This system has changed the traditional concept,from the original point into a continuous mode,change the existing auto phase control mode,does not need the corresponding sensing device is embedded in the line,improve the reliability,simplifies equipment and maintenance.At the same time,combining with the engineering application experience of automatic passing phase separation in the ShuoHuang railway,some engineering application problems in the application process are solved according to the experiment.Device through the use of assessment,the indicators meet the design requirements. |
