YG－WY H型電動互輪車智能充電器有(you)電壓(ya)輸出(chu)，但充不(bu)進去電。

　　根據故障現象，初步判斷電源輸人整流電路部分有故障，有可能是輸出電源插頭與充電插座接觸不良所致。用十字旋具將充電器的(de)(de)(de)4顆緊(jin)固(gu)螺釘拆下，打開上(shang)蓋。首(shou)先看到輸八整流(liu)電(dian)(dian)(dian)路(lu)申的(de)(de)(de)咆源(yuan)濾波(bo)電(dian)(dian)(dian)容C5（82 uF/400V）已(yi)炸裂(lie)、漏液(ye)。然后用萬用表：“R*1”擋(dang)測(ce)(ce)量(liang)(liang)輸出電(dian)(dian)(dian)源(yuan)插(cha)頭(tou)和充(chong)(chong)(chong)電(dian)(dian)(dian)插(cha)座，發現(xian)阻(zu)值(zhi)很(hen)小，幾乎為(wei)0Ω，這說明它們接觸良好。為(wei)了萬無一失(shi)，再用萬用表測(ce)(ce)量(liang)(liang)其他易損壞的(de)(de)(de)元件及充(chong)(chong)(chong)電(dian)(dian)(dian)保險管，相關的(de)(de)(de)電(dian)(dian)(dian)路(lu)圖(tu)如圖(tu)1 所示。經測(ce)(ce)量(liang)(liang)均(jun)未損壞。最后換(huan)上(shang)一個與(yu)原來(lai)的(de)(de)(de)耐(nai)壓（耐(nai)壓可大(da)于原來(lai)的(de)(de)(de)值(zhi)，但絕對不(bu)能(neng)小于原來(lai)的(de)(de)(de)值(zhi)）和容量(liang)(liang)相同的(de)(de)(de)電(dian)(dian)(dian)解電(dian)(dian)(dian)容（82 n F／400∨），焊好，插(cha)上(shang)電(dian)(dian)(dian)源(yuan)插(cha)頭(tou)和充(chong)(chong)(chong)電(dian)(dian)(dian)插(cha)頭(tou)，經數小時的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)，充(chong)(chong)(chong)龜器上(shang)的(de)(de)(de)“充(chong)(chong)(chong)滿(man)”指示燈亮，表明蓄(xu)電(dian)(dian)(dian)池已(yi)充(chong)(chong)(chong)滿(man)，故障排除。
