| 改造DF4D內燃機車電路 減少輔控回路過電壓故障(37 卷) |
| 英文標題 |
| Improving the Circuit of DF4D Diesel Locomotive to Reduce the Overvoltage Problem in the Auxiliary Controlling Circuit |
| 摘要 |
| 當DF4D內燃機車在運行中由輔助發(fā)電狀態(tài)直接轉入固定發(fā)電狀態(tài)，而機車乘務員又不能準確判斷，人為用手拖動輔助發(fā)電勵磁接觸器FLC時，將引起機車啟動發(fā)電機電壓突升，輔控電路瞬間產生過電壓，導致燒損機車監(jiān)控主機、監(jiān)控顯示屏、勵調器、無線列調、信號等車載電子設備，嚴重影 |
