 一(yi)、故障表征(zheng)　　

　　一次柴(chai)油(you)發電機(ji)(ji)租賃日(ri)常運(yun)(yun)行(xing)維護操作申，對某柴(chai)油(you)機(ji)(ji)潤滑油(you)系(xi)統(tong)、燃袖系(xi)統(tong)、冷卻水(shui)系(xi)統(tong)和起動系(xi)統(tong)等進(jin)行(xing)檢查(cha)準備(bei);用機(ji)(ji)旁操縱手輪對柴(chai)油(you)機(ji)(ji)進(jin)行(xing)起動、調速、停車(che)及換(huan)向(xiang)操作測試正(zheng)常，備(bei)車(che)程序結束(shu)后(hou)交給駕(jia)駛室操縱。柴(chai)袖機(ji)(ji)運(yun)(yun)行(xing)約(yue)lOmin后(hou)，換(huan)向(xiang)操作時突然停車(che)，運(yun)(yun)行(xing)監控(kong)系(xi)統(tong)報警提示換(huan)向(xiang)操作失敗。

于是(shi)再(zai)次起動(dong)(dong)柴(chai)油機(ji)，但(dan)未能成功(gong)，監(jian)控系(xi)統顯示操(cao)縱系(xi)統故障。隨(sui)后在(zai)機(ji)艙(cang)用(yong)(yong)操(cao)縱手輪操(cao)作柴(chai)油機(ji)，發現柴(chai)油機(ji)起動(dong)(dong)和換向(xiang)時(shi)，需要(yao)先將操(cao)縱手輪置(zhi)(zhi)于順車(che)或倒車(che)的位置(zhi)(zhi)，用(yong)(yong)手推動(dong)(dong)起動(dong)(dong)輔助手柄向(xiang)順車(che)或倒車(che)方向(xiang)偏轉(zhuan)(zhuan)來實現;柴(chai)油機(ji)起動(dong)(dong)運轉(zhuan)(zhuan)后，則(ze)可由操(cao)縱手輪完成調速(su)與(yu)停(ting)車(che)指(zhi)令的操(cao)作。　

　　該柴(chai)油(you)機為8320CZ型柴(chai)油(you)機，有關(guan)參(can)數如下:額定轉速428Mmin;活塞行程(cheng)480mm;額定功率97OkW(132Ohp);壓縮空氣起動可逆轉直列式四沖程(cheng)柴(chai)油(you)機。機艙集中監控與(yu)報警系統(tong)采用FCS現場總(zong)線系統(tong)與(yu)雙(shuang)機冗余(yu)設計，自(zi)動化監測系統(tong)使(shi)用OPC體系C/S應用模式和分布式控制系統(tong)，的操作(zuo)平(ping)臺為Windowsxp操作(zuo)系統(tong)，為ForceControl6?0實時應用軟件(jian)。　

　　二、故(gu)障(zhang)檢修(xiu)　

　　柴(chai)(chai)油(you)發電機(ji)租賃操(cao)(cao)(cao)縱(zong)系統狀(zhuang)態正常良好(hao)時，對柴(chai)(chai)油(you)機(ji)操(cao)(cao)(cao)作(zuo)既可通過安(an)裝在機(ji)旁(pang)的操(cao)(cao)(cao)縱(zong)手輪完成，也可以由(you)集控室遙控操(cao)(cao)(cao)作(zuo)實現。柴(chai)(chai)油(you)機(ji)出現這種操(cao)(cao)(cao)縱(zong)故(gu)障很(hen)大程(cheng)度上(shang)影響著(zhu)機(ji)器的使用性(xing)能和安(an)全系數，對此，必須對柴(chai)(chai)油(you)機(ji)故(gu)障原(yuan)因(yin)作(zuo)進(jin)一步分析檢查。

發電機租賃(lin)啟動換向(xiang)操作失靈故障及排(pai)除方法　　

1、燒毀(hui)(hui)電(dian)動(dong)機。如(ru)果電(dian)壓(ya)太低超過10%，電(dian)機電(dian)流將(jiang)增加，線圈(quan)溫度將(jiang)升高。嚴重時使機械(xie)設備(bei)停止運轉或(huo)無法(fa)啟動(dong)，甚至燒毀(hui)(hui)電(dian)動(dong)機；

   2、光線很暗。電(dian)壓(ya)降(jiang)(jiang)(jiang)低5%，普通點(dian)燈的照度(du)下降(jiang)(jiang)(jiang)18%；電(dian)壓(ya)下降(jiang)(jiang)(jiang)10%，照度(du)下降(jiang)(jiang)(jiang)35%；電(dian)壓(ya)降(jiang)(jiang)(jiang)低20%。則日光燈無(wu)法(fa)啟動；

   3、增(zeng)大線損。在輸送一定電力時(shi)，電壓(ya)降低，電流相應增(zeng)大，引(yin)起線損增(zeng)大；

   4、降(jiang)(jiang)低(di)電(dian)力系統的(de)靜態和瞬態穩定性。隨著電(dian)壓(ya)(ya)的(de)降(jiang)(jiang)低(di)，相(xiang)應(ying)降(jiang)(jiang)低(di)線路輸送極(ji)限(xian)容(rong)量，穩定性降(jiang)(jiang)低(di)，電(dian)壓(ya)(ya)過低(di)可能(neng)會發生電(dian)壓(ya)(ya)崩潰事(shi)故；

   5、發電機出(chu)力(li)降低(di)。如果電壓下降超過5%，發電機輸出(chu)也會相應下降。

   6、影響電壓(ya)的穩定性(xing)。如果區域無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)補償不足，無(wu)(wu)功(gong)(gong)的缺(que)(que)額只(zhi)能(neng)由電壓(ya)降低來(lai)補償，導致無(wu)(wu)功(gong)(gong)缺(que)(que)額越(yue)(yue)來(lai)越(yue)(yue)大，電壓(ya)越(yue)(yue)來(lai)越(yue)(yue)低，直至崩潰。

   這表(biao)明(ming)發(fa)電(dian)(dian)(dian)機(ji)的低(di)(di)電(dian)(dian)(dian)壓(ya)運行對(dui)發(fa)電(dian)(dian)(dian)機(ji)的安 全使用構成重(zhong)大(da)威脅，每個人都需(xu)要警惕低(di)(di)電(dian)(dian)(dian)壓(ya)情況。當電(dian)(dian)(dian)壓(ya)嚴重(zhong)異常而影響發(fa)電(dian)(dian)(dian)機(ji)工作時，需(xu)要立即將(jiang)發(fa)電(dian)(dian)(dian)機(ji)與電(dian)(dian)(dian)力(li)系統斷開，以保(bao)護發(fa)電(dian)(dian)(dian)機(ji)免受(shou)損壞。
