KZ4A型机车交流电机及其控制系统的综合试验

Combined testing of AC motors and their control system on type KZ4A locomotive

文章主要介绍了利用滚动试验台进行KZ4A型高速客运电力机车逆变器供电的交流电机及其控制系统综合试验的方法及验证机车牵引/电制动性能的结果,并对其试验结果与机车线路试验结果进行了比对,得出滚动试验台模拟线路负载完全满足机车牵引/电制动特性试验要求。

Presented in this paper are the method of combined testing of AC motors and their control system for inverter on type KZ4A high-speed passenger electric locomotive and its test results for verifying locomotive traction/electric brake characteristics. Comparison is made between test results from the roller running rig test and locomotive line running test. It is concluded that using the roller running rig can fully meet the requirements of locomotive traction electric brake characteristics tests.
