定(ding)期巡檢(jian)(jian)(jian)(jian)制度(du)(du)：建(jian)立完(wan)善的(de)定(ding)期巡檢(jian)(jian)(jian)(jian)制度(du)(du)是(shi)(shi)保(bao)障配(pei)電柜正(zheng)常(chang)(chang)運行(xing)的(de)重要(yao)措施。巡檢(jian)(jian)(jian)(jian)人(ren)員應按照(zhao)規定(ding)的(de)周期（一(yi)(yi)般(ban)每周至少一(yi)(yi)次(ci)）對(dui)配(pei)電柜進行(xing)全面(mian)檢(jian)(jian)(jian)(jian)查，檢(jian)(jian)(jian)(jian)查內容包括(kuo)電氣元件(jian)(jian)(jian)的(de)工作狀(zhuang)態，查看斷路(lu)器、接(jie)觸器等元件(jian)(jian)(jian)的(de)觸點是(shi)(shi)否有燒蝕(shi)、氧化現(xian)象，指示(shi)燈是(shi)(shi)否正(zheng)常(chang)(chang)顯示(shi)；檢(jian)(jian)(jian)(jian)查接(jie)線(xian)端(duan)子是(shi)(shi)否松(song)動，通(tong)過觀(guan)察(cha)和(he)使用工具進行(xing)緊(jin)固(gu)，防止因(yin)(yin)接(jie)線(xian)松(song)動導致接(jie)觸不良、發熱等問題；監測(ce)電氣元件(jian)(jian)(jian)的(de)溫(wen)度(du)(du)，使用紅(hong)外測(ce)溫(wen)儀(yi)檢(jian)(jian)(jian)(jian)測(ce)關鍵部(bu)位的(de)溫(wen)度(du)(du)，如母線(xian)連接(jie)處、開關觸點等，當發現(xian)溫(wen)度(du)(du)異(yi)常(chang)(chang)升高時(shi)，及時(shi)查找原因(yin)(yin)并(bing)進行(xing)處理；此外，還需檢(jian)(jian)(jian)(jian)查配(pei)電柜的(de)通(tong)風(feng)(feng)散熱情況，確保(bao)風(feng)(feng)扇正(zheng)常(chang)(chang)運轉(zhuan)，通(tong)風(feng)(feng)口無堵塞。

清(qing)(qing)潔(jie)保養工(gong)作：定期對配電(dian)柜內部進行(xing)(xing)清(qing)(qing)潔(jie)是防止電(dian)氣(qi)(qi)故障的(de)重要手段。由(you)于(yu)(yu)配電(dian)柜在運行(xing)(xing)過(guo)程(cheng)中會(hui)產生靜電(dian)，容易吸附(fu)灰(hui)塵，灰(hui)塵積(ji)聚(ju)過(guo)多(duo)會(hui)影響(xiang)電(dian)氣(qi)(qi)元(yuan)(yuan)件(jian)(jian)的(de)散熱性能，甚至可能導致絕緣性能下降，引發短路等故障。因(yin)此，每隔(ge)一段時間（一般(ban)每季度一次），應使(shi)用(yong)干燥的(de)壓縮空氣(qi)(qi)或吸塵器對配電(dian)柜內部進行(xing)(xing)清(qing)(qing)潔(jie)，清(qing)(qing)除灰(hui)塵和雜(za)物；對于(yu)(yu)頑固污漬，可使(shi)用(yong)干凈的(de)軟布蘸(zhan)取適(shi)量的(de)專(zhuan)用(yong)清(qing)(qing)潔(jie)劑進行(xing)(xing)擦拭，但需(xu)注意避免清(qing)(qing)潔(jie)劑進入電(dian)氣(qi)(qi)元(yuan)(yuan)件(jian)(jian)內部；在清(qing)(qing)潔(jie)過(guo)程(cheng)中，還應檢查電(dian)氣(qi)(qi)元(yuan)(yuan)件(jian)(jian)的(de)固定情況，確保無(wu)松動、脫落現象(xiang)。

元(yuan)(yuan)件(jian)(jian)更(geng)(geng)換(huan)(huan)與升(sheng)級(ji)：隨(sui)著使用(yong)時間(jian)的增長，配電柜(ju)內的電氣元(yuan)(yuan)件(jian)(jian)會逐漸(jian)老化，其性(xing)(xing)能(neng)(neng)和(he)(he)可(ke)靠性(xing)(xing)也會隨(sui)之下降。當發現電氣元(yuan)(yuan)件(jian)(jian)出現老化、損(sun)壞等(deng)問(wen)題時，應及時進行更(geng)(geng)換(huan)(huan)。在(zai)更(geng)(geng)換(huan)(huan)元(yuan)(yuan)件(jian)(jian)時，必須選擇與原型號、規格相(xiang)同或兼容的產(chan)品，并(bing)嚴格按照操作規程(cheng)進行安(an)裝和(he)(he)接線；此外，隨(sui)著電力技術(shu)的不斷發展，為了(le)提(ti)高配電柜(ju)的性(xing)(xing)能(neng)(neng)和(he)(he)安(an)全性(xing)(xing)，還可(ke)以(yi)根據實際需(xu)求對部分元(yuan)(yuan)件(jian)(jian)進行升(sheng)級(ji)改造(zao)，例如(ru)將傳(chuan)統的電磁式斷路器更(geng)(geng)換(huan)(huan)為智能(neng)(neng)型斷路器，增加(jia)漏電保護(hu)、通信功能(neng)(neng)等(deng)，提(ti)升(sheng)配電柜(ju)的智能(neng)(neng)化水平和(he)(he)故障診斷能(neng)(neng)力 。
