在電器設備的(de)安裝(zhuang)與運作維護(hu)保(bao)養中，人們經常會遇上(shang)不一(yi)樣的(de)電氣故(gu)障，提早(zao)對(dui)故(gu)障的(de)歸類有一(yi)個總體的(de)了(le)解(jie)有益(yi)于鑒別(bie)故(gu)障的(de)種類，迅速找到解(jie)決(jue)方案。對(dui)提升勞動(dong)者生(sheng)產(chan)制造(Produce)率(productivity)，降低(di)財產(chan)損失（loss)和生(sheng)產(chan)安全都具備積(ji)意義，下邊金屬材料表箱生(sheng)產(chan)廠家就(jiu)帶大伙兒一(yi)起了(le)解(jie)一(yi)下電器設備故(gu)障的(de)詳盡歸類。
依照(zhao)電(dian)氣設備的組成(cheng)特性，從搜索電(dian)氣故(gu)障的見解(jie)考(kao)慮，普遍的電(dian)氣故(gu)障可分(fen)成(cheng)三(san)類
一、電源故障(zhang)
缺電(dian)(dian)源(yuan)、工作(zuo)電(dian)(dian)壓、頻率(frequency)誤差、旋光性(xing)接反、相(xiang)線和中性(xing)點(dian)接反、缺一相(xiang)電(dian)(dian)源(yuan)、相(xiang)序更(geng)改(gai)、交(jiao)直流電(dian)(dian)源(yuan)搞混。
二、電源(yuan)電路(lu)故障(zhang)
斷開、短路故(gu)障(zhang)(電流量沒經大功(gong)率電器(qi)、立即連電源兩方面(mian))、短路，接地裝置、布線不(bu)正確。
三、機器設備(bei)和元器件(jian)故障
超溫損(sun)壞、不可以(yi)運作、電氣熱擊穿、特性變(bian)劣。
依據故(gu)障(zhang)狀況剖析(Analyse)故(gu)障(zhang)原(yuan)(yuan)(yuan)因，是(shi)(shi)搜索電(dian)(dian)(dian)氣故(gu)障(zhang)的(de)重要（表(biao)述:形容事(shi)情的(de)關鍵(jian)構成(cheng))。剖析的(de)基(ji)本(ben)是(shi)(shi)安裝電(dian)(dian)(dian)工基(ji)礎(chu)基(ji)礎(chu)理論，是(shi)(shi)對(dui)電(dian)(dian)(dian)氣設備的(de)結構、基(ji)本(ben)原(yuan)(yuan)(yuan)理、特性的(de)充足了(le)解，是(shi)(shi)與(yu)故(gu)障(zhang)實際上的(de)融合。某一電(dian)(dian)(dian)氣故(gu)障(zhang)造成(cheng)的(de)原(yuan)(yuan)(yuan)因將會（maybe)許多，關鍵(jian)的(de)是(shi)(shi)在諸多原(yuan)(yuan)(yuan)因中(zhong)找(zhao)到關鍵(jian)的(de)原(yuan)(yuan)(yuan)因，并應(ying)(ying)用(yong)(yong)方(fang)式去清(qing)除（Remove)故(gu)障(zhang)。比如(ru)：假如(ru)電(dian)(dian)(dian)動(dong)機是(shi)(shi)次應(ying)(ying)用(yong)(yong)，就(jiu)需從(cong)電(dian)(dian)(dian)源、電(dian)(dian)(dian)源電(dian)(dian)(dian)路、電(dian)(dian)(dian)動(dong)機和負荷各個方(fang)面開(kai)展(zhan)巡視剖析；假如(ru)電(dian)(dian)(dian)動(dong)機是(shi)(shi)經(jing)維修后次應(ying)(ying)用(yong)(yong)，就(jiu)應(ying)(ying)著手于電(dian)(dian)(dian)動(dong)機自身的(de)查(cha)驗剖析；假如(ru)電(dian)(dian)(dian)動(dong)機運行(xing)一段時(shi)間(jian)忽然不可以運行(xing)，就(jiu)需從(cong)電(dian)(dian)(dian)源及操(cao)縱（control)元器件層面開(kai)展(zhan)查(cha)驗預測。歷經(jing)左右全(quan)過程，從(cong)而明確(que)電(dian)(dian)(dian)動(dong)機故(gu)障(zhang)的(de)實際原(yuan)(yuan)(yuan)因。
掌握(wo)電器設備故(gu)障的(de)類(lei)型，有利于在故(gu)障產生(sheng)時選準故(gu)障原因(yin)，立即找(zhao)到解決(jue)方案，防止多余的(de)損害（loss)。
