| 改造DF4D內(nèi)燃機(jī)車電路 減少輔控回路過(guò)電壓故障(37 卷) |
| 英文標(biāo)題 |
| Improving the Circuit of DF4D Diesel Locomotive to Reduce the Overvoltage Problem in the Auxiliary Controlling Circuit |
| 摘要 |
| 當(dāng)DF4D內(nèi)燃機(jī)車在運(yùn)行中由輔助發(fā)電狀態(tài)直接轉(zhuǎn)入固定發(fā)電狀態(tài)，而機(jī)車乘務(wù)員又不能準(zhǔn)確判斷，人為用手拖動(dòng)輔助發(fā)電勵(lì)磁接觸器FLC時(shí)，將引起機(jī)車啟動(dòng)發(fā)電機(jī)電壓突升，輔控電路瞬間產(chǎn)生過(guò)電壓，導(dǎo)致燒損機(jī)車監(jiān)控主機(jī)、監(jiān)控顯示屏、勵(lì)調(diào)器、無(wú)線列調(diào)、信號(hào)等車載電子設(shè)備，嚴(yán)重影 |
