Diagnostics and monitoring of railway automation and remote control power supply devices

This article is devoted to the research of diagnostics and monitoring of power supply devices of railway automation and remote control. The analysis of failure statistics of power supply devices in recent years has been carried out and the most vulnerable elements of power supply systems have been identified on its basis. Objects are described, the state of which must be diagnosed in the input devices, in switchgears, as well as the diagnostic parameters of the battery and the backup power station; the principles of determining their technical condition are presented. The authors for the first time proposed technical solutions for increasing the survivability of power supply devices in case of poor-quality external power supply. The article also presents possible solutions for the implementation of diagnostics of monitored facilities, which save time spent by personnel on maintenance to reduce operational costs, improve the reliability of the power supply of automation and remote control, which will improve the safety, uninterrupted operation and efficiency of the transportation process.
