摘　　要：针对电力机车过分相时产生的过电压和涌流造成危害,本文提出一种基于NI公司的DAQ数据采集卡和LabVIEW的同步关合控制系统。本系统采用数据采集、分析处理软件LabVIEW和PCI-6024E数据采集卡,实时测量系统电压、电流信号的过零点;采用自适应算法控制断路器在电压零点投入和在电流零点切除永磁真空断路器,以降低关合时产生的过电压和涌流.通过计算机仿真和实验的对比,验证了设计的可靠性、稳定性和正确性.A new type synchronous closing controller based on DAQ and LabVIEW is developed to Electric Locomotive for reducing the switching over voltage and high inrush currents. The controller based on data acquisition , analyze ＆ processing software LabVIEW and PCI-6024E realizes real-time measurement of tracks voltage ＆current zero points; an adaptive algorithm is adopted to minimize the affects of drifts ofactuator＇s operating time for closing magnetic vacuum circuit-breaker at the voltage zero point and opening at the current zero point.The computer simulation and test results show that the synchronous controlleris reliable, works smoothly and validity.
