HXD3D型电力机车主断路器无法闭合的故障分析

Fault Analysis on Failure of Main Circuit Breaker of HXD3D Electric Locomotive

针对HXD3D型电力机车微机显示屏在无故障提示的情况下主断路器无法闭合的问题,通过实际情况并结合微机控制网络系统控制逻辑进行分析,进而提出微机网络控制系统的改进建议。

In view of the problem that the main circuit breaker can not be closed without fault prompt,the microcomputer display screen of HXD3D electric locomotive is analyzed through the actual situation and combined with the control logic of microcomputer control network system.Then the improvement suggestion of microcomputer network control system is put forward.
