摘要
根据我国目前铁路行业标准和电力机车主机厂现有技术条件,设计开发了一种新型的全自动数字式牵引变压器综合测试与故障诊断系统;通过对牵引变压器试验电源系统的研究和归纳,依据试验中对电源容量要求和接线方式的不同,将整个测试系统分为功能电源部分、上层工控机控制系统、可编程序控制器控制系统和变频调速系统;现场运行表明,利用该系统可以大大提高工作效率,且各项试验数据精确,可靠性高。
According to the existing railway industry standards trod technologies, a digital comprehensive test system have beca developed,which is used for the traction transformer testing and fauh diagnosis.Afler analyzing on lractioll lransformer lest power systetn, we can summarizing lheir characlerislics. Based on the reqNired power capacily and wiring conneciioll of the different testing, the system can be divided into four paris： functional power, the upper induslrial control compuler system, PLC control systems and frequency conversion lira ing system. Praclice has proved that the system can greatly＇ improve efficiency, and all accurate alld high reliable tesling data can be obtained.
