What Role Does The Ups Uninterruptible Power Supply Play In Railway Power Supply Systems?

After entering the 21st century, my country's railway signal equipment has achieved rapid development. In this case, the power supply screen that used to apply power frequency technology can no longer meet the use requirements in the current environment, and the power supply system has gradually shown low reliability and intelligence. In this case, Uninterruptible Power Supply(UPS) has become an important part of the power supply system construction.

With more and more new equipment and new technologies being applied in the railway field, many power supply equipment have higher requirements for power supply quality and power supply stability. UPS uninterruptible power supply not only guarantees the quality of the power supply system, but also ensures the uninterruptibility of power supply.

When the external network power supply is interrupted, the UPS uninterruptible power supply can also continue to ensure the normal operation of the signal system for a certain period of time. During this emergency period, the dispatching staff can promptly direct the train to a safe area and store the train operation data to avoid the impact of data loss on the operation of the system. According to the characteristics of the signal system itself, we generally design the UPS in a redundant way. Under this design method, if a UPS has a problem during operation, the system will switch to another backup UPS in time to ensure the stability of power supply.
