迁曹电气化铁路信号系统供电新技术的实现

Implementation of a New Power Supply Technology for Qian-Cao Electric Railway Signal System

采用交直交电源代替二路贯通电源是近年来一项新的铁路信号系统供电技术。阐述了交直交电源的工作原理,对迁曹电气化铁路应用该技术进行了探讨并就现场测试数据给出了具体分析。测试结果表明,从接触网接引的电源经过交直交电源装置后谐波含量总畸变率低于国家标准,完全满足信号系统对电源质量的要求。针对交直交电源运行过程中出现的技术问题,提出了相应的解决措施。

The use of AC-DC-AC power supply to instead of the power continuous is a new technology on the railway signal system in recent years. The working principle of AC-DC-AC power supply is introduced,discussed on this technology applied to the Qian-Cao Electric Railway and analyzed the site test data. The test results show that the total harmonic distortion rate of the power supply from the catenary system which through the AC-DC-AC power supply is less than the national standard and fully satisfy with the requirements of signal system power quality. For the technical problems arising in the process of AC-DC-AC power supply,the corresponding solutions are also put forward.
