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。貴州電氣更換廠家在設(shè)備未通電時，判定電氣設(shè)備按鈕、接觸器、熱繼電器以及保險(xiǎn)絲的好壞，從而判定故障的所在。</p><div

1．先普遍后非凡因裝配配件質(zhì)量或其他設(shè)備故障而引起的故障，一般占常見故障的50左右。電氣設(shè)備的非凡故障多為軟故障，要靠經(jīng)驗(yàn)和儀表來測量和維修。 2．先**后內(nèi)部先不要急于更換損壞的電氣部件，在確認(rèn)**設(shè)備電路正常時，再考慮更換損壞的電氣部件。 3．先直流后交流檢修時，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)。 4．先故障后調(diào)試對于調(diào)試和故障并存的電氣設(shè)備，應(yīng)先排除故障，再進(jìn)行調(diào)試，調(diào)試必須在電氣線路速的前提下進(jìn)行。貴州電氣更換廠家</p><p
