和谐型交流电力机车复合冷却器试验台设计 摘要：随着中国经济持续增长，铁路货运需求也随之增加，2002年以来，我国采取引进、消化、吸收的方式，逐步推广单机牵引5,000吨级重载列车的大功率交流电力机车。为保障安全，新型高速重载机车在规定时间的运行作业后必须检修，但国内目前尚无配套的检修试验装置。 本课题论述和谐型交流电力机车复合冷却器试验台的设计，详细分析了复合冷却器的性能要求，规划了实验台的功能，提出了总体设计方案，阐明了系统设计要求和试验参数，完成了复合冷却器试验台的硬件设计，进行了压力、流量、真空度传感器的选型，对电气元件如电机、继电器-接触器也进行了参数计算和选型。压力传感器选用AUTO-VP4-H系列通用压力传感器/变送器，流量传感器选用YF-21流量传感器；真空度传感器选用PTJ410F采集，通过PCI1710数据采集卡将数据传送至上位机；继电器选用欧姆龙一般通用中间继电器MY-J系列，电机选用Y系列中小型三相异步电动机。基于KingView组态软件开发了监控界面，利用动画连接函数设计仿真界面，实现了对通风机组测试状态的动态监控，利用ACCESS数据库进行实时数据的记录和查询，调用PRINT函数实现了报表打印。 经南车集团襄阳国铁机电有限公司的实际应用，该系统实现和谐型大功率电力机车的通风机组性能检测，具有自动化程度高的特点。 关键词：监控系统；组态软件；电力机车；复合冷却器；数据采集； Dive pump test-bed duct comprehensive relays Abstract：With Chinas sustained economic growth and increased demand for rail freight since 2002, China adopted the introduction, digestion, absorption, and gradually promote the single 5,000-ton heavy train traction power AC electric locomotives. To ensure safety, the new high-speed heavy locomotive operating in a specified time after the operation must overhaul, but the maintenance of domestic support is currently no test equipment. This topic discusses the Harmony AC electric locomotive composite cooler test bed design, detailed analysis of the performance of the composite cooling requirements of the functions planned for the test bed, the overall design scheme is proposed to clarify the system design requirements and test parameters, complete Cooler test bed complex hardware design, for the pressure, flow, vacuum sensor selection, electrical components such as motors, relays - contactors have also been calculated and the selection of parameters. Pressure sensors use AUTO-VP4-H Series Universal pressure sensor / transmitters, flow sensors used YF-21 flow sensors; vacuum sensors used PTJ410F acquisition, through the PCI1710 data acquisition card to transfer data first bit machine; relay selection Omron General use intermediate relay MY-J series, the motor selection of small and medium three-phase induction motor Y serie
