Urban Rail Transit Signal Power Supply Solution---ups Power Supply

The emergence of urban rail transit has provided great convenience for people's daily travel. In recent years, it has been built in many cities in my country. In the operation of trains, the signal system can be said to be an important guarantee for the safe and stable operation of trains. In order to enable it to work more stably, a very important element is to have a stable and high-quality power supply system. In this case, Uninterruptible Power Supply(UPS) was introduced and became an important part of the construction of rail transit signal systems.

UPS uninterruptible power supply is a modern power supply device with voltage and frequency stabilization, which contains energy storage devices and is mainly composed of rectifiers and inverters. It has the functions of isolating interference, frequency conversion and uninterrupted switching, and is very suitable for application in today's urban rail transit construction. At the same time, UPS and its supporting batteries can store electricity while supplying power on a daily basis. If the external power supply fails or is interrupted, it will continue to provide power through the inverter. Not only does it need to have a stable voltage and frequency, but it also needs to ensure the uninterrupted power supply.
