1.母線(xian)槽長期(qi)運(yun)行時至(zhi)少每年定期(qi)檢(jian)修一(yi)次(ci)。

2.檢查(cha)總(zong)的負載電(dian)流不(bu)得超過設計(ji)電(dian)流和主母線槽的額定電(dian)流。母線槽檢(jian)(jian)修前(qian)需(xu)對母線槽系(xi)統進行停(ting)電檢(jian)(jian)查(cha)!完全切斷母線槽所有電(dian)(dian)(dian)(dian)源!并用萬用電(dian)(dian)(dian)(dian)表測量導電(dian)(dian)(dian)(dian)體(ti)(ti)有無(wu)電(dian)(dian)(dian)(dian)壓，確認母線槽系統(tong)未帶(dai)電(dian)(dian)(dian)(dian)方可例行檢修。防(fang)止高電(dian)(dian)(dian)(dian)壓對操作人員構(gou)成(cheng)身(shen)體(ti)(ti)傷害甚至死亡的(de)嚴(yan)重事(shi)故!

3.母(mu)線槽(cao)運行中(zhong)，應不間(jian)斷查(cha)看整條系(xi)統的四(si)周(zhou)是否(fou)存在滲漏、噴(pen)水、潛在的潮氣(qi)源，是否(fou)存在對系(xi)統構成威脅(xie)的重物，以及對母(mu)線槽(cao)系(xi)統溫升構成影響(xiang)的熱源，檢查(cha)有(you)無異(yi)物進(jin)入母(mu)線槽(cao)內部(bu)。檢查(cha)母(mu)線槽(cao)系(xi)統零部(bu)件有(you)無缺損(sun)、銹蝕(shi)現(xian)象、支架彈簧是否(fou)有(you)合(he)適的彈力(li)，發現(xian)問題后立(li)即更換。

4.母線槽長期運行時(shi)每(mei)年(nian)定期檢測一次接(jie)(jie)頭溫(wen)升(sheng)，接(jie)(jie)頭溫(wen)升(sheng)應按照GB7251標(biao)準不超過70℃為合格(ge)(環(huan)境(jing)溫(wen)度為40℃)。檢查(cha)所有(you)母線槽接(jie)(jie)頭連接(jie)(jie)螺栓及導(dao)(dao)電體接(jie)(jie)觸部(bu)分(fen)是(shi)否(fou)有(you)松動(dong)現(xian)(xian)(xian)象(xiang)(xiang)。防(fang)止因松動(dong)產生的阻值增高(gao)而使接(jie)(jie)頭產生發(fa)熱現(xian)(xian)(xian)象(xiang)(xiang)。檢查(cha)絕(jue)(jue)緣材料是(shi)否(fou)有(you)老化現(xian)(xian)(xian)象(xiang)(xiang)，導(dao)(dao)電部(bu)分(fen)是(shi)否(fou)有(you)熔化變形現(xian)(xian)(xian)象(xiang)(xiang)。如發(fa)現(xian)(xian)(xian)有(you)相間(jian)接(jie)(jie)地、絕(jue)(jue)緣擊穿現(xian)(xian)(xian)象(xiang)(xiang)，應分(fen)段拆除并用耐(nai)壓測試(shi)儀分(fen)段檢查(cha)，找出(chu)故障，或(huo)重新更換母線槽，或(huo)重新進行絕(jue)(jue)緣包覆處理。檢查(cha)母線槽系統(tong)的插(cha)接(jie)(jie)箱插(cha)腳與(yu)母排接(jie)(jie)觸是(shi)否(fou)良好。

5.定(ding)期清除母線槽系統表面積塵，確保散熱(re)良好。

6.母線槽系統檢修完畢，重新送電(dian)(dian)前(qian)，應檢查絕緣(yuan)電(dian)(dian)阻并有完整(zheng)的檢修記錄。
