3．先直流后交流檢修時(shí)，必須先檢查直流回路靜態(tài)工作點(diǎn)，再交流回路動態(tài)工作點(diǎn)。

(一)電阻測試法電阻測試法是一種常用的測量方法。通常是指利用萬用表的電阻檔，測量電機(jī)、線路、觸頭等是否符合使用標(biāo)稱值以及是否通斷的一種方法，或用兆歐表測量相與相、相與地之間的絕緣電阻等。測量時(shí)，注意選擇所使用的量程與校對表的準(zhǔn)確性，一般使用電阻法測量時(shí)通用做法是先選用低檔，同時(shí)要注意被測線路是否有回路，并嚴(yán)禁帶電測量。 (二)電壓測試法電壓測試法是指利用萬用表相應(yīng)的電壓檔，測量電路中電壓值的一種方法。通常測量時(shí)，有時(shí)測量電源、負(fù)載的電壓，有時(shí)也測量開路電壓，以判斷線路是否正常。測量時(shí)應(yīng)注意表的檔位，選擇合適的量程，一般測量未知交流或開路電壓時(shí)通常選用電壓的較高級，以確保不至于在高電壓低量程下進(jìn)行操作，以免把表損壞;同時(shí)測量直流時(shí)，要注意正負(fù)極性。 (三)電流測試法電流測試法是通常測量線路中的電流是否符合正常值，以判斷故障原因的一種方法。對弱電回路，常采用將電流表或萬用表電流檔串接在電路中進(jìn)行測量;對強(qiáng)電回路，常采用鉗形電流表檢測。</p><p style="text-indent:25px">電氣檢查方法逐步開路（或接入）法：多支路并聯(lián)且控制較復(fù)雜的電路短路或接地時(shí)，一般有明顯的外部表現(xiàn)，如冒煙、有火花等。電動機(jī)內(nèi)部或帶有護(hù)罩的電路短路、接地時(shí)，除熔斷器熔斷外，不易發(fā)現(xiàn)其他外部現(xiàn)象。這種情況可采用逐步開路（或接入）法檢查。逐步開路法：碰到難以檢查的短路或接地故障，可重新更換熔體，把多支路交聯(lián)電路，一路一路逐步或重點(diǎn)地從電路中斷開，然后通電試驗(yàn)，若熔斷器一再熔斷，故障就在剛剛斷開的這條電路上。然后再將這條支路分成幾段，逐段地接入電路。當(dāng)接入某段電路時(shí)熔斷器又熔斷，故障就在這段電路及某電器元件上。這種方法簡單，但輕易把損壞不嚴(yán)重的電器元件徹底燒毀。逐步接入法：電路出現(xiàn)短路或接地故障時(shí)，換上新熔斷器逐步或重點(diǎn)地將各支路一條一條的接入電源，重新試驗(yàn)。當(dāng)接到某段時(shí)熔斷器又熔斷，故障就在剛剛接入的這條電路及其所包含的電器元件上。氣維護(hù)是指技術(shù)工程師利用專業(yè)儀器對電氣設(shè)備，包括發(fā)電機(jī)、變壓器、電力線路、斷路器等設(shè)備的專業(yè)維護(hù)。</p><div

1.電源故障:缺電源、電壓、頻率偏差、極性接反、相線和中性線接反、缺一相電源、相序改變、交直流混 2.電路故障:斷線、短路、短接，接地、接線錯誤。 3.設(shè)備和元件故障:過熱燒毀、不能運(yùn)行、電氣擊穿、性能變劣。根據(jù)故障現(xiàn)象分析故障原因，是查找電氣故障的關(guān)鍵。分析的基礎(chǔ)是電工基本理論，是對電氣裝置的構(gòu)造、原理、性能的充分理解，是與故障實(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，并運(yùn)用方法去排除故障。例如，某三相籠型異步電動機(jī)出現(xiàn)了不能運(yùn)轉(zhuǎn)的故障，不論是什么情況，較集中的表現(xiàn)是電動機(jī)不能工作，但故障不一定是在電動機(jī)，而可能是電源故障，也可能是電路故障或者是設(shè)備和元件故障等。也就是說，同一種故障形式，故障的原因多種多樣。在這些原因中，到底是哪個(gè)方面的原因使電動機(jī)不能運(yùn)轉(zhuǎn)，還要經(jīng)過更深入、更詳細(xì)的分析。對于生疏的設(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。云南老設(shè)備電氣更換哪里有</p><p
