出(chu)現(xian)問題(ti)不良現(xian)象一：無(wu)交流電輸(shu)出(chu)功(gong)(gong)率輸(shu)出(chu)或(huo)輸(shu)出(chu)功(gong)(gong)率輸(shu)出(chu)不平穩
倘若保(bao)(bao)險金絲是(shi)完好(hao)性(xing)的，在有電(dian)機負債(zhai)的根(gen)本(ben)原(yuan)(yuan)因(yin)下，各級黨(dang)委交(jiao)流電(dian)相電(dian)壓無所在。這(zhe)些(xie)根(gen)本(ben)原(yuan)(yuan)因(yin)最(zui)主要的是(shi)以(yi)下根(gen)本(ben)原(yuan)(yuan)因(yin)致使(shi)的：電(dian)原(yuan)(yuan)中(zhong)展現串(chuan)入，電(dian)壓擊(ji)(ji)穿(chuan)癥狀(zhuang)，過(guo)(guo)壓，過(guo)(guo)電(dian)壓保(bao)(bao)護的控(kong)制用電(dian)線(xian)路(lu)系(xi)統展現內部故障，諧(xie)振控(kong)制用電(dian)線(xian)路(lu)系(xi)統還沒有事(shi)情，電(dian)原(yuan)(yuan)電(dian)機負債(zhai)過(guo)(guo)大，高頻(pin)整流濾波控(kong)制用電(dian)線(xian)路(lu)系(xi)統中(zhong)整流穩壓管被電(dian)壓擊(ji)(ji)穿(chuan)，濾波電(dian)解電(dian)容漏電(dian)等。
維護保養(yang)培訓做法(fa)：第一，用(yong)(yong)(yong)萬用(yong)(yong)(yong)表(biao)在(zai)(zai)線(xian)(xian)(xian)(xian)校正一些低頻(pin)變電(dian)(dian)(dian)(dian)器次級的有幾個元電(dian)(dian)(dian)(dian)子元器件(jian)什(shen)么(me)(me)狀況(kuang)下(xia)不利(li)壞。在(zai)(zai)排查(cha)了(le)低頻(pin)整(zheng)流(liu)(liu)整(zheng)流(liu)(liu)穩壓(ya)管熱擊穿、額定(ding)負載燒壞的狀況(kuang)后，但是在(zai)(zai)在(zai)(zai)線(xian)(xian)(xian)(xian)校正各工(gong)作(zuo)模(mo)擬(ni)輸(shu)送(song)(song)高端的電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)值，如若這時候工(gong)作(zuo)模(mo)擬(ni)輸(shu)送(song)(song)仍為零，則行充分(fen)肯定(ding)是主(zhu)機(ji)(ji)直流(liu)(liu)電(dian)(dian)(dian)(dian)的抑(yi)(yi)制(zhi)直流(liu)(liu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)路出(chu)了(le)故章。抑(yi)(yi)制(zhi)直流(liu)(liu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)路的倆個分(fen)是集成系統電(dian)(dian)(dian)(dian)開關主(zhu)機(ji)(ji)直流(liu)(liu)電(dian)(dian)(dian)(dian)抑(yi)(yi)制(zhi)器和過壓(ya)維護直流(liu)(liu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)路。最終(zhong)用(yong)(yong)(yong)萬用(yong)(yong)(yong)表(biao)靜止在(zai)(zai)線(xian)(xian)(xian)(xian)校正低頻(pin)濾波(bo)直流(liu)(liu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)路中整(zheng)流(liu)(liu)整(zheng)流(liu)(liu)穩壓(ya)管及高壓(ya)低壓(ya)濾波(bo)電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容什(shen)么(me)(me)狀況(kuang)下(xia)傷(shang)害(hai)。如若我(wo)覺(jue)得一些的元器件(jian)傷(shang)害(hai)，在(zai)(zai)換個好新的完整(zheng)，的元器件(jian)后，開機(ji)(ji)藍(lan)屏自測，大部分(fen)故章就能排查(cha)。是需要解(jie)釋的是：主(zhu)機(ji)(ji)直流(liu)(liu)電(dian)(dian)(dian)(dian)工(gong)作(zuo)模(mo)擬(ni)輸(shu)送(song)(song)線(xian)(xian)(xian)(xian)斷開或(huo)開焊，虛焊也會引發這般故章。在(zai)(zai)維護保養(yang)培訓應(ying)該把冷卻(que)水(shui)提前(qian)準備這一點點。
發動機故障現(xian)像二：有直(zhi)(zhi)流變壓器(qi)變壓器(qi)電阻降(jiang)輸送，但(dan)輸送直(zhi)(zhi)流變壓器(qi)變壓器(qi)電阻降(jiang)過低
這對于類似這些錯誤(wu)碼的(de)問題，要根據售后維(wei)修技術 所知，除(chu)穩壓設(she)定電線會吸引工作(zuo)輸(shu)入(ru)(ru)電流過低(di)外，還很多(duo)理由會吸引工作(zuo)輸(shu)入(ru)(ru)電流過低(di)，主耍有下(xia)面幾點鐘:
1.旋轉(zhuan)24v電(dian)電(dian)開(kai)關電(dian)原(yuan)(yuan)(yuan)(yuan)負乘載(zai)短路(lu)(lu)(lu)等問(wen)題(ti)出現問(wen)題(ti)的問(wen)題(ti)。于此，應切斷旋轉(zhuan)24v電(dian)電(dian)開(kai)關電(dian)原(yuan)(yuan)(yuan)(yuan)用電(dian)線路(lu)(lu)(lu)原(yuan)(yuan)(yuan)(yuan)理的一切阻(zu)抗(kang)(kang)，以區分(fen)處理是(shi)(shi)旋轉(zhuan)24v電(dian)電(dian)開(kai)關電(dian)原(yuan)(yuan)(yuan)(yuan)用電(dian)線路(lu)(lu)(lu)原(yuan)(yuan)(yuan)(yuan)理或者是(shi)(shi)阻(zu)抗(kang)(kang)用電(dian)線路(lu)(lu)(lu)原(yuan)(yuan)(yuan)(yuan)理有出現問(wen)題(ti)的問(wen)題(ti)。若(ruo)切斷阻(zu)抗(kang)(kang)用電(dian)線路(lu)(lu)(lu)原(yuan)(yuan)(yuan)(yuan)理直流電(dian)壓(ya)輸(shu)出電(dian)壓(ya)正常值，表示是(shi)(shi)阻(zu)抗(kang)(kang)過(guo)大;若(ruo)仍不對常，情(qing)況說明開(kai)關按鈕主機電(dian)源線路(lu)(lu)(lu)有故障(zhang)率。
2.輸(shu)入電(dian)流端(duan)整流場效應管、濾波電(dian)容(rong)（電(dian)容(rong)器）失靈等，能夠經(jing)由代換法(fa)對其進行分辯。
3.打開工作功率管(guan)的的性能減(jian)低(di)，必定出(chu)現打開管(guan)沒法常規導通，使電源(yuan)適配(pei)器的電阻增大，帶負荷(he)力減(jian)低(di)。
4.開(kai)關按鈕輸出管的源極(S極)，普通(tong)接(jie)這(zhe)個阻(zu)值非常小，但(dan)工作(zuo)效率(lv)(lv)更大的電(dian)(dian)容，對于短路保護好在線(xian)檢測電(dian)(dian)容，此(ci)電(dian)(dian)容的阻(zu)值應該在0.2到(dao)0.8直接(jie)。此(ci)功率(lv)(lv)電(dian)(dian)阻(zu)如(ru)變值或(huo)開(kai)焊(han)，排(pai)斥不恰當的也會(hui)出現效果電(dian)(dian)流值過低的故(gu)障率(lv)(lv)。
5.中頻變電器異(yi)常(chang)情況，就導(dao)致傳(chuan)輸交(jiao)流電壓急(ji)劇(ju)下(xia)降，還(huan)是導(dao)致電電開關輸出功率管激烈不(bu)足之處而屢損(sun)電電開關管。
6. 油田交流(liu)電濾波電容(rong)(rong)（電容(rong)(rong)器）惡意，容(rong)(rong)易造成電源線帶額定(ding)額定(ding)負載(zai)作用差，一接額定(ding)額定(ding)負載(zai)輸送(song)電流(liu)值便驟降。
7.電(dian)原打印輸(shu)出精(jing)度線了解較差，還有一個定的(de)了解熱敏電(dian)阻，會(hui)造(zao)成(cheng)打印輸(shu)出精(jing)度端電(dian)壓過(guo)低。
8.農電(dian)線(xian)交流電(dian)流值能(neng)否(fou)過(guo)低(di)。既然打(da)開輸(shu)出(chu)功率降適配器在低(di)壓低(di)下卻仍然能(neng)打(da)出(chu)額定值的(de)線(xian)交流電(dian)流值值，但當(dang)農電(dian)線(xian)交流電(dian)流值小于打(da)開輸(shu)出(chu)功率降適配器的(de)最低(di)值線(xian)交流電(dian)流值限制值時，也會使(shi)打(da)出(chu)線(xian)交流電(dian)流值過(guo)低(di)。
返(fan)修(xiu)(xiu)保(bao)養方(fang)法步(bu)驟：相對(dui) 這錯誤咱們(men)能夠 表(biao)(biao)明上(shang)(shang)述(shu)錯誤原因(yin)分析(xi)，來(lai)順次(ci)(ci)對(dui)其開(kai)(kai)(kai)(kai)展(zhan)逐(zhu)步(bu)觀(guan)察(cha)。但(dan)在真正(zheng)(zheng)返(fan)修(xiu)(xiu)保(bao)養時(shi)，可表(biao)(biao)明真正(zheng)(zheng)的(de)(de)(de)情況來(lai)對(dui)其開(kai)(kai)(kai)(kai)展(zhan)逐(zhu)步(bu)觀(guan)察(cha)，不(bu)(bu)某種要(yao)順次(ci)(ci)逐(zhu)步(bu)觀(guan)察(cha)。第(di)一用(yong)萬用(yong)表(biao)(biao)觀(guan)察(cha)一次(ci)(ci)高電(dian)(dian)(dian)(dian)(dian)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)源濾波濾波電(dian)(dian)(dian)(dian)(dian)容(rong)有沒(mei)有變(bian)(bian)(bian)質(zhi)，余量有沒(mei)有減低，是(shi)(shi)否平常充蓄電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)。如(ru)無(wu)上(shang)(shang)述(shu)癥狀，則校正(zheng)(zheng)一次(ci)(ci)旋轉(zhuan)開(kai)(kai)(kai)(kai)關輸出功(gong)率(lv)(lv)(lv)管的(de)(de)(de)柵(zha)極(ji)(G極(ji))的(de)(de)(de)限流(liu)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值還有源極(ji)(S極(ji))的(de)(de)(de)過(guo)流(liu)守護查(cha)測量電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)值會不(bu)(bu)變(bian)(bian)(bian)值，變(bian)(bian)(bian)質(zhi)或(huo)(huo)開(kai)(kai)(kai)(kai)焊，接(jie)觸(chu)惡(e)意(yi)。經判別后，如(ru)果(guo)沒(mei)有間題，自己就查(cha)一番中頻率(lv)(lv)(lv)干(gan)(gan)(gan)式(shi)(shi)(shi)干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)力(li)(li)低壓(ya)變(bian)(bian)(bian)壓(ya)器(qi)的(de)(de)(de)鐵(tie)(tie)(tie)芯會不(bu)(bu)良好無(wu)損音樂。因(yin)在每天的(de)(de)(de)生話的(de)(de)(de)使(shi)(shi)用(yong)中，不(bu)(bu)行切勿的(de)(de)(de)重(zhong)摔或(huo)(huo)重(zhong)幢，使(shi)(shi)中頻率(lv)(lv)(lv)干(gan)(gan)(gan)式(shi)(shi)(shi)干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)力(li)(li)低壓(ya)變(bian)(bian)(bian)壓(ya)器(qi)的(de)(de)(de)鐵(tie)(tie)(tie)芯損毀。使(shi)(shi)中頻率(lv)(lv)(lv)干(gan)(gan)(gan)式(shi)(shi)(shi)干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)力(li)(li)低壓(ya)變(bian)(bian)(bian)壓(ya)器(qi)的(de)(de)(de)磁通量，磁光感(gan)應承載力(li)(li)，和磁路(lu)等(deng)也(ye)會受極(ji)大的(de)(de)(de)導致，帶來(lai)文件(jian)傳遞的(de)(de)(de)效果(guo)，電(dian)(dian)(dian)(dian)(dian)能會大半價扣(kou)。根據中頻率(lv)(lv)(lv)干(gan)(gan)(gan)式(shi)(shi)(shi)干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)力(li)(li)低壓(ya)變(bian)(bian)(bian)壓(ya)器(qi)要(yao)為增(zeng)加渦旋，大中頻率(lv)(lv)(lv)學習交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)文件(jian)傳遞效果(guo)，它的(de)(de)(de)鐵(tie)(tie)(tie)芯是(shi)(shi)用(yong)軟(ruan)吸鐵(tie)(tie)(tie)石氧機(ji)制作而成的(de)(de)(de)。一些磁塊物料有高的(de)(de)(de)導磁率(lv)(lv)(lv)，但(dan)質(zhi)脆，易碎。由此(ci)(ci)(ci)它的(de)(de)(de)損毀率(lv)(lv)(lv)也(ye)是(shi)(shi)很(hen)高的(de)(de)(de)。由此(ci)(ci)(ci)在維修(xiu)(xiu)費時(shi)1000萬不(bu)(bu)可忘啦查(cha)此(ci)(ci)(ci)地(di)，切勿走彎路(lu)。除(chu)此(ci)(ci)(ci)本身以及或(huo)(huo)許即使(shi)(shi)模擬輸出濾波電(dian)(dian)(dian)(dian)(dian)容(rong)（電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)）存儲空間變(bian)(bian)(bian)低，甚至于失(shi)容(rong)或(huo)(huo)開(kai)(kai)(kai)(kai)焊，虛接(jie);主機(ji)主機(ji)電(dian)(dian)(dian)(dian)(dian)源效果(guo)限流(liu)熱(re)敏電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)變(bian)(bian)(bian)值或(huo)(huo)虛接(jie)，主機(ji)主機(ji)電(dian)(dian)(dian)(dian)(dian)源效果(guo)線虛接(jie)等(deng)。在實(shi)計維修(xiu)(xiu)部時(shi)，某些影響(xiang)因(yin)素(su)都最(zui)好不(bu)(bu)要(yao)招惹，都應審核下，以保(bao)證質(zhi)量百無(wu)一失(shi)。
