style="font-size:16px;">分割法對電器電路是由多個模塊或多個電路板及轉(zhuǎn)插件組合起來的電路，應(yīng)用起來較方便，例如：某電器的直流保險絲熔斷，說明負(fù)載電流過大，同時導(dǎo)致電源輸出電壓下降。要確定故障原因，可將電流表串在直流保險絲處，然后應(yīng)用分割法將懷疑的那一部分電路與總電路分割開。這時看總電流的變化，若分割開某部分電路后電流降到正常值，說明故障就在分割出來的電路中。分割法依其分割法不同有對分法、特征點分割法、經(jīng)驗分割法及逐點分割法等。所謂對分法，是指把整個電路先一分為二，測出故障在哪一半電路中；然后將有故障一半電路再一分為二，這樣一次又一次分為二，直到檢測出故障為止。經(jīng)驗分割法則是根據(jù)人們的經(jīng)驗，估計故障在哪一級，那么將該級的輸入、輸出端作為分割點。逐點分割法，是指按信號的傳輸順序，由前到后或由后到前逐級加以分割。其實，在上面介紹的信號注入法已經(jīng)采用了分割法。應(yīng)用分割法檢測電路時要小心謹(jǐn)慎，有些電路不能隨便斷開的要給予重視，不</span><span style="font-size:16px;">然故障沒排除，還會添新的故障。</span> </p><p> <span style="font-size:16px;">短路法是用一只電容或一根跨接線來短路電路的某一部分或某一元件，使之暫時失去作用，從而來判斷故障的一種檢測方法。2．應(yīng)用短路法主要適用于檢修故障電器中產(chǎn)生的噪聲、交流聲或其他干擾信號等，對于判斷電路是否有阻斷性故障十分有效。應(yīng)用短路法檢測電路過程中，對于低電位，可直接用短接線直接對地短路；對于高電位、應(yīng)采用交流短路，即用20μF以上的電解電容對地短接，保證直接高電位不變；對電源電路不能隨便使用短路法。例如：有一臺收音機(jī)噪聲大，這時可用一只100μF電容器，從檢波級開路將其輸入、輸出端短路接地，這樣逐級往后進(jìn)行。當(dāng)短路某一級的輸入端時，收音機(jī)仍有噪聲，而短路其輸出端即無噪聲時，那么該級是噪聲源也是故障級。從上述介紹中可看到，短路法實質(zhì)上是一種特殊的分割法。</span>
