style="text-indent:25px">掌握電氣故障排除的方法： (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">電氣設(shè)備操作與維修人員的要求： 1、施工現(xiàn)場內(nèi)臨時(shí)用電的施工和維修必須由經(jīng)過培訓(xùn)后取得上崗證書的專業(yè)電工完成，電工的等級應(yīng)同工程的難易程度和技術(shù)復(fù)雜性相適應(yīng)，初級電工不允許進(jìn)行中、高級電工的作業(yè)。 2、各類用電人員應(yīng)做到： (1)掌握安全用電基本知識和所用設(shè)備的性能； (2)使用設(shè)備前必須按規(guī)定穿戴和配備好相應(yīng)的勞動防護(hù)用品；并檢查電氣裝置和保護(hù)設(shè)施是否完好。嚴(yán)禁設(shè)備帶“病”運(yùn)轉(zhuǎn)； (3)停用的設(shè)備必須拉閘斷電，鎖好開關(guān)箱；

(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，通過追蹤與故障相關(guān)聯(lián)的信號，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整個系統(tǒng)和單元電路的工作原理有清楚的理解。
