1．強迫閉合法在排隊電器故障時，經(jīng)過直觀檢查后沒有找到故障點而手下也沒有適當?shù)膬x表進行測量，可用一絕緣棒將有關(guān)繼電器、接觸器、電磁鐵等用外力強行按下，使其常開觸點閉合，然后觀察電器部分或機械部分出現(xiàn)的各種現(xiàn)象，如電動機從不轉(zhuǎn)到轉(zhuǎn)動，山東老機電電氣更換平臺，設(shè)備相應(yīng)的部分從不動到正常運行等。 2．短接法設(shè)備電路或電器的故障大致歸納為短路、過載、斷路、接地、接線錯誤、電器的電磁及機械部分故障等六類。諸類故障中出現(xiàn)較多的為斷路故障。它包括導(dǎo)線斷路、虛連、松動、觸點接觸不良、虛焊、假焊、熔斷器熔斷等。對這類故障除用電阻法，山東老機電電氣更換平臺，山東老機電電氣更換平臺、電壓法檢查外，還有一種更為簡單可靠的方法，就是短接法。方法是用一根良好絕緣的導(dǎo)線，將所懷疑的斷路部位短路接起來，如短接到某處，電路工作恢復(fù)正常，說明該處斷路。具體操作可分為局部短接法和長短接法。許多故障都是由臟污及導(dǎo)電塵塊引起的，一經(jīng)清潔故障往往會排除。山東老機電電氣更換平臺</p><div

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、線路、觸頭等是否符合使用標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，注意選擇所使用的量程與校對表的準確性，一般使用電阻法測量時通用做法是先選用低檔，同時要注意被測線路是否有回路，并嚴禁帶電測量。 (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，有時測量電源、負載的電壓，有時也測量開路電壓，以判斷線路是否正常。測量時應(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行操作，以免把表損壞;同時測量直流時，要注意正負極性。 (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行測量;對強電回路，常采用鉗形電流表檢測。配電箱、開關(guān)箱內(nèi)的各種電器應(yīng)按規(guī)定的位置緊固在安裝板上，不得歪斜和松動。</p><div style="width:100%;text-align:
