GE控制系统(AC)接地保护原理与故障点快速诊断

GE control system(AC)grounding protection principle and rapid diagnosis of fault points

为了快速判断和处理GE控制系统(AC)接地故障,分析了交流电动轮卡车接地保护电路的主要部件的作用及接地保护电路的工作原理,通过wPTU软件来对卡车实时运行数据进行数据分析,可以快速地判别接地故障的大概范围。结果表明:通过此处理方法可以大大地提高维修工作效率,避免了因盲目维修而造成的不必要损失。

In order to quickly judge and deal with the ground fault of GE control system(AC),the article analyzes the function of the main components of the grounding protection circuit of the AC electric wheel truck and the working principle of the grounding protection circuit,and analyzes the real-time operation data of the truck by the wPTU software,and quickly determines the approximate range of the ground fault.The results show that this method can greatly improve the efficiency of maintenance work and avoid unnecessary losses caused by blind maintenance.
