| 摘 要： | 在铁路行车信号设备运行中，安全可靠供电是保证铁路运输的基础。在利用接触网作为信号设备第2路电源时，既有接触网供电装置由于没有对电源的电压波动、干扰谐波进行净化处理，经常出现烧坏设备的情况，急需进行优化改造。采用直流环节实现输入电压和输出电压解耦装置，有效地解决了输入电压品质差的问题。

| Abstract: | The safety and reliability of signal power is the base of railway transportation.The signal power often makes use of the catenaries as standby power supply.The signal equipment is often damaged due to voltage fluctuation and harmonic interference.To solve such issues of poor quality input voltage,the paper gives a design of DC decoupling device between input voltage and output voltage. |
