1.大(da)功率蓄電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)指(zhi)(zhi)示(shi)燈不(bu)亮,充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)指(zhi)(zhi)示(shi)燈也不(bu)亮。檢查充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器輸(shu)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)插(cha)頭與市電(dian)(dian)(dian)(dian)(dian)(dian)有(you)(you)沒(mei)有(you)(you)連接(jie)好,可將(jiang)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器輸(shu)入(ru)(ru)插(cha)頭插(cha)至(zhi)正(zheng)常(chang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)插(cha)座中試一(yi)下,如(ru)情(qing)況依舊,將(jiang)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器外殼打開(kai),觀察一(yi)下機內(nei)保險絲(si)(si)有(you)(you)沒(mei)有(you)(you)斷,如(ru)沒(mei)有(you)(you)斷,先檢查一(yi)下電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸(shu)入(ru)(ru)線是(shi)(shi)否良好,在排(pai)除電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)輸(shu)入(ru)(ru)線的(de)(de)故障后,應(ying)檢查一(yi)下電(dian)(dian)(dian)(dian)(dian)(dian)路板上(shang)(shang)高壓區(qu)附近(jin)的(de)(de)元器件是(shi)(shi)否有(you)(you)虛(xu)焊(han),保險絲(si)(si)座是(shi)(shi)否有(you)(you)接(jie)觸不(bu)良現象,重(zhong)點(dian)檢查變壓器T1、三(san)極管(guan)(guan)V1、V2等是(shi)(shi)否有(you)(you)虛(xu)焊(han)現象。另外,R5或R6開(kai)路,也會(hui)(hui)引起上(shang)(shang)述故障,如(ru)機內(nei)保險絲(si)(si)已斷,則千萬不(bu)要(yao)(yao)更換(huan)大(da)安(an)培的(de)(de)保險絲(si)(si)管(guan)(guan)(充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)保險絲(si)(si)管(guan)(guan)一(yi)般為2A),應(ying)重(zhong)點(dian)檢查D1-D4、V1、V2、R4、R7及D15、D21有(you)(you)無損(sun)(sun)(sun)壞,如(ru)有(you)(you)損(sun)(sun)(sun)壞,可用同類型的(de)(de)更換(huan)。請注(zhu)意,上(shang)(shang)述元件損(sun)(sun)(sun)壞時(shi),可能會(hui)(hui)同時(shi)損(sun)(sun)(sun)壞一(yi)到二個(ge),有(you)(you)時(shi)可能會(hui)(hui)同時(shi)損(sun)(sun)(sun)壞好幾個(ge),檢修時(shi)需要(yao)(yao)逐一(yi)檢查、更換(huan)這些元件后才(cai)能通電(dian)(dian)(dian)(dian)(dian)(dian)。
2.大(da)功率(lv)蓄電池充電機(ji)發熱量大(da)、且伴有異常響(xiang)聲。故障原因(yin)是(shi)輸出級(ji)消振(zhen)阻容R31、C17損(sun)壞所致。另外,C12開路或(huo)虛焊也會引起上述故障。
3.大功率蓄電池充電機工作時有異常響聲,充不進電。檢查電路板上C8是否有虛焊或損壞,一般更換C8均能解決.上海施能電器設(she)備有限(xian)公司始(shi)建于(yu)1984年,上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機系列放電機系列充放電機等電器產品。
