广州地铁一二八增购车辅助逆变器拓展设计研究与分析

摘要

广州地铁一二八增购车调试工作中发现，在进行辅助逆变器拓展作业中，当切除一节车的辅助逆变器时，同一单元内其余2个辅助逆变器发生报黄的故障，对此进行深入研究，并提出了相应的整改措施。%The paper is focused on the development of auxiliary inverter in debugging the added metros in No.128 of Guangzhou Metro, during which the other two auxiliary inverters in the same unit will cause a yellow fault when the auxiliary inverter of one section is cut. Therefore,the paper gives a deeper study of it and propose the corresponding rectification measures.
