YG－WY H型電動互輪車智能充電器有電(dian)壓輸出，但充(chong)不進去電(dian)。

　　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)4顆(ke)緊固螺釘拆下(xia)，打(da)開(kai)上(shang)(shang)蓋。首(shou)先(xian)看(kan)到輸八整流電(dian)(dian)(dian)路申的(de)咆源濾波電(dian)(dian)(dian)容C5（82 uF/400V）已炸裂、漏(lou)液。然后(hou)用(yong)萬(wan)用(yong)表(biao)：“R*1”擋測(ce)量輸出電(dian)(dian)(dian)源插頭和充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)插座，發(fa)現阻(zu)值(zhi)很(hen)小(xiao)(xiao)，幾(ji)乎為(wei)0Ω，這說明它(ta)們接觸良好。為(wei)了萬(wan)無一(yi)失，再用(yong)萬(wan)用(yong)表(biao)測(ce)量其他易損壞的(de)元件及(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)保險管，相關的(de)電(dian)(dian)(dian)路圖(tu)如圖(tu)1 所(suo)示(shi)。經測(ce)量均未損壞。最(zui)后(hou)換上(shang)(shang)一(yi)個與原來(lai)(lai)的(de)耐(nai)(nai)壓(ya)（耐(nai)(nai)壓(ya)可(ke)大于原來(lai)(lai)的(de)值(zhi)，但絕對(dui)不能小(xiao)(xiao)于原來(lai)(lai)的(de)值(zhi)）和容量相同的(de)電(dian)(dian)(dian)解電(dian)(dian)(dian)容（82 n F／400∨），焊好，插上(shang)(shang)電(dian)(dian)(dian)源插頭和充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)插頭，經數小(xiao)(xiao)時的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，充(chong)(chong)(chong)(chong)龜器上(shang)(shang)的(de)“充(chong)(chong)(chong)(chong)滿(man)”指示(shi)燈亮，表(biao)明蓄電(dian)(dian)(dian)池(chi)已充(chong)(chong)(chong)(chong)滿(man)，故障排除。
