摘要
为准确检测和谐型电力机车DC 600 V供电装置的各项性能,提高测试效率,基于阻感性负载试验原理,设计一种适用于和谐型电力机车DC 600 V供电装置性能检测的自动化试验系统,采用LabVIEW平台开发测试系统的应用软件,通过TestSand软件对试验过程进行序列化管理,并应用试验系统,对空载和满载工况下DC 600 V供电装置的电流、电压和接地故障情况进行现场测试。测试结果表明,该试验系统可以实现在多种运行工况下机车DC 600 V供电装置的电压、电流和接地故障情况的准确检测,满足机车DC 600 V供电装置检修要求。
In order to accurately detect the performance of the DC 600 V power supply and improve test efficiency,based on the principle of resistive load test,an automated test system for performance detection of DC 600 V power supply devices of harmony electrical locomotives was proposed.By using LabVIEW platform,the test system application software was developed,and TestSand software was used to serialized the test process.The current,voltage and grounding faults of DC 600 V power supply device under noload and full load conditions were tested with the test system.The test results indicated that the test system could realize the detection of the voltage,current and grounding faults of the locomotive DC 600 V power supply unit in a variety of operations,which met the maintenance requirements of the locomotive DC 600 V power supply device.
