軌道交通系統電源子系統

摘要：軌道交通信號系統是軌道交通的指揮者，而軌道交通信號系統電源子系統則是整個信號系統的心臟。一套穩定、可靠的供電系統，是信號系統的基礎保障，也是保障軌道交通有序、快速運行的根本保障。本文主要介紹城市軌道交通信號電源的
架構和原理，及其設計時的一些要點。 敘詞：軌道交通系統，信號系統，電源子系統 Abstract：While rail transportation signal system is the conductor of rail transportation, power supply subsystem for rail transportationsignal system is the heart of the whole signal system. A reliable and stable power supply system is primary not only for the signal system,but also for the orderly and swift functioning of rail transportation. The paper mainly introduces the basci structure and principle of signalpower supply for urban rail transportation, and also sheds some light on the key points for the design.
