style="text-indent:25px">在確定故障點(diǎn)以后，無(wú)論是修復(fù)還是更換，排除故障相對(duì)電氣維修人員來(lái)說，一般比查找故障要簡(jiǎn)單得多。但在排除故障中一般不可能只用單一的方法，往往多種方法綜合運(yùn)用。 1.在排除故障的過程中，應(yīng)先動(dòng)腦、后動(dòng)手，正確分析可以起到事半功倍的效果。具體應(yīng)遵循先外部后內(nèi)部、先機(jī)械后電氣、先靜后動(dòng)、先公用后**、先簡(jiǎn)單后復(fù)雜、先一般后特殊的原則。需要注意的是，不要一遇到故障，拿起表就測(cè)，拿起工具就拆。要養(yǎng)成良好的分析、判斷習(xí)慣，要做到每次測(cè)量均有明確的目的，即測(cè)量的結(jié)果能說明什么。在找出有故障點(diǎn)的組件后，應(yīng)該進(jìn)一步確定引起故障的根本原因。例如:當(dāng)電路板內(nèi)的一只晶體管被燒壞，單純地更換一個(gè)晶體管是不夠的，重要的是要查出被燒壞的原因，并采取補(bǔ)救和預(yù)防的措施。 2.一般情況下，以設(shè)備的動(dòng)作順序?yàn)榕懦龝r(shí)分析、檢測(cè)的次序。以此為前提，先檢查電源，再檢查線路和負(fù)載;先檢查公共回路再檢查各分支回路;先檢查主電路再檢查控制電路;先檢查容易檢測(cè)的部分(如各控制柜)，再檢查不易檢測(cè)的部分(如某一設(shè)備的控制器件)。配電箱、開關(guān)箱安裝要端正、牢固，移動(dòng)式的箱體應(yīng)裝設(shè)在堅(jiān)固的支架上。廣東電氣更換哪里有</p><p
