(一)調(diào)整參數(shù)法有些情況，出現(xiàn)故障時(shí)，線路中元器件不一定壞，線路接觸也良好，只是由于某些物理量調(diào)整得不合適或運(yùn)行時(shí)間長(zhǎng)了，有可能因外界因素致使系統(tǒng)參數(shù)發(fā)生改變或不能自動(dòng)修正系統(tǒng)值，從而造成系統(tǒng)不能正常工作，這時(shí)應(yīng)根據(jù)設(shè)備的具體情況進(jìn)行調(diào)整。 (二)原理分析法根據(jù)控制系統(tǒng)的組成原理圖，通過(guò)追蹤與故障相關(guān)聯(lián)的信號(hào)，進(jìn)行分析判斷，找出故障點(diǎn)，并查出故障原因。使用本方法要求維修人員對(duì)整個(gè)系統(tǒng)和單元電路的工作原理有清楚的理解。 (三)比較、分析、判斷法它是根據(jù)系統(tǒng)的工作原理，控制環(huán)節(jié)的動(dòng)作程序以及它們之間的邏輯關(guān)系，結(jié)合故障現(xiàn)象，進(jìn)行比較、分析和判斷，減少測(cè)量與檢查環(huán)節(jié)，并迅速判斷故障范圍。山西機(jī)電電氣更換平臺(tái)熔斷器的熔體更換時(shí)，嚴(yán)禁用不符合原規(guī)格的熔體代替。</p><div

1．測(cè)量電壓法測(cè)量電壓法是根據(jù)電器的供電方式，測(cè)量各點(diǎn)的電壓值與電流值并與正常值比較。具體可分為分階測(cè)量法、分段測(cè)量法和點(diǎn)測(cè)法。 2．測(cè)電阻法可分為分階測(cè)量法和分段測(cè)量法。這兩種方法適用于開(kāi)關(guān)、電器分布距離較大的電氣設(shè)備。 3．對(duì)比、置換元件、逐步開(kāi)路（或接入）法（1）對(duì)比法：把檢測(cè)數(shù)據(jù)與圖紙資料及平時(shí)記錄的正常參數(shù)相比較來(lái)判定故障。對(duì)無(wú)資料又無(wú)平時(shí)記錄的電器，可與同型號(hào)的完好電器相比較。電路中的電器元件屬于同樣控制性質(zhì)或多個(gè)元件共同控制同一設(shè)備時(shí)，可以利用其他相似的或同一電源的元件動(dòng)作情況來(lái)判定故障。（2）置轉(zhuǎn)換元件法：某些電路的故障原因不易確定或檢查時(shí)間過(guò)長(zhǎng)時(shí)，但是為了保證電氣設(shè)備的利用率，可轉(zhuǎn)換同一相性能良好的元器件實(shí)驗(yàn)，以證實(shí)故障是否由此電器引起。運(yùn)用轉(zhuǎn)換元件法檢查時(shí)應(yīng)注重，當(dāng)把原電器拆下后，要認(rèn)真檢查是否已經(jīng)損壞，只有肯定是由于該電器本身因素造成損壞時(shí)，才能換上新電器，以免新?lián)Q元件再次損壞。</p><p style="text-indent:25px">電氣維修常識(shí)： 1．先動(dòng)口再動(dòng)手對(duì)于有故障的電氣設(shè)備，不應(yīng)急于動(dòng)手，應(yīng)先詢問(wèn)產(chǎn)生故障的前后經(jīng)過(guò)及故障現(xiàn)象。對(duì)于生疏的設(shè)備，還應(yīng)先熟悉電路原理和結(jié)構(gòu)特點(diǎn)，遵守相應(yīng)規(guī)則。拆卸前要充分熟悉每個(gè)電氣部件的功能、位置、連接方式以及與四周其他器件的關(guān)系，在沒(méi)有組裝圖的情況下，應(yīng)一邊拆卸，一邊畫草圖，并記上標(biāo)記。 2．先外部后內(nèi)部應(yīng)先檢查設(shè)備有無(wú)明顯裂痕、缺損，了解其維修史、使用年限等，然后再對(duì)機(jī)內(nèi)進(jìn)行檢查。拆前應(yīng)排隊(duì)周邊的故障因素，確定為機(jī)內(nèi)故障后才能拆卸，否則，盲目拆卸，可能將設(shè)備越修越壞。 3．先機(jī)械后電氣只有在確定機(jī)械零件無(wú)故障后，再進(jìn)行電氣方面的檢查。檢查電路故障時(shí)，應(yīng)利用檢測(cè)儀器尋找故障部位，確認(rèn)無(wú)接觸不良故障后，再有針對(duì)性地查看線路與機(jī)械的運(yùn)作關(guān)系，以免誤判。因裝配配件質(zhì)量或其他設(shè)備故障而引起的故障，一般占常見(jiàn)故障的50左右。</p><div

1、觀察和調(diào)查故障現(xiàn)象電氣故障現(xiàn)象是多種多樣的。例如，同一類故障可能有不同的故障現(xiàn)象，不同類故障可能有同種故障現(xiàn)象，這種故障現(xiàn)象的同一性和多樣性，給查找故障帶來(lái)復(fù)雜性。但是，故障現(xiàn)象是檢修電氣故障的基本依據(jù)，是電氣故障檢修的起點(diǎn)，因而要對(duì)故障現(xiàn)象進(jìn)行仔細(xì)觀察、分析，找出故障現(xiàn)象中較主要的、較典型的方面，搞清故障發(fā)生的時(shí)間、地點(diǎn)、環(huán)境等。 2、分析故障原因，初步確定故障范圍、縮小故障部位根據(jù)故障現(xiàn)象分析故障原因是電氣故障檢修的關(guān)鍵。分析的基礎(chǔ)是電工電子基本理論，是對(duì)電氣設(shè)備的構(gòu)造、原理、性能的充分理解，是電工電子基本理論與故障實(shí)際的結(jié)合。某一電氣故障產(chǎn)生的原因可能比較多，重要的是在眾多原因中找出較主要的原因。 3、確定故障的部位，判斷故障點(diǎn) 確定故障部位是電氣故障檢修的較終目的和結(jié)果。確定故障部位可理解成確定設(shè)備的故障點(diǎn)，如短路點(diǎn)、損壞的元器件等，也可理解成確定某些運(yùn)行參數(shù)的變異，如電壓波動(dòng)、三相不平衡等。確定故障部位是在對(duì)故障現(xiàn)象進(jìn)行周密的考察和細(xì)致分析的基礎(chǔ)上進(jìn)行的。在這一過(guò)程中，往往要采用下面將要介紹的多種手段和方法。配電箱、開(kāi)關(guān)箱周圍應(yīng)有足夠兩人同時(shí)工作的空間，其周圍不得堆放任何有礙操作、維修的物品。山西機(jī)電電氣更換平臺(tái)</p><p
