這個時(shi)候(hou)應該將電(dian)(dian)(dian)(dian)源(yuan)驅動(dong)(dong)(dong)(dong)板(ban)(ban)及主(zhu)板(ban)(ban)拆下(xia)(xia),著重檢查下(xia)(xia)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)上是(shi)否有(you)損壞的(de)部分,如有(you)損壞的(de)元器件(jian)就更換掉,作(zuo)好初步(bu)維修后接著使用(yong)上面(mian)介紹的(de)直流(liu)電(dian)(dian)(dian)(dian)源(yuan)單獨給板(ban)(ban)子上電(dian)(dian)(dian)(dian)并開起(qi)來(lai),接著需要使用(yong)電(dian)(dian)(dian)(dian)子示波(bo)(bo)器測量(liang)六(liu)(liu)路(lu)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)上電(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否相同(tong),當給定一(yi)個啟動(dong)(dong)(dong)(dong)信號(hao)時(shi)六(liu)(liu)路(lu)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)的(de)波(bo)(bo)形是(shi)否一(yi)致;如果(guo)手里沒有(you)電(dian)(dian)(dian)(dian)子示波(bo)(bo)器的(de)話,也可以嘗(chang)試(shi)使用(yong)數字式(shi)電(dian)(dian)(dian)(dian)子萬用(yong)表來(lai)測量(liang)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)六(liu)(liu)路(lu)的(de)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya),一(yi)般(ban)來(lai)說,未啟動(dong)(dong)(dong)(dong)時(shi)的(de)每路(lu)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)上的(de)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)約為10V左右,啟動(dong)(dong)(dong)(dong)后的(de)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)約為2-3V,如果(guo)測量(liang)結果(guo)一(yi)切正常的(de)話,基本(ben)可以判(pan)斷此變頻器的(de)驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)是(shi)好的(de)。
,它包(bao)括了變頻器加速(su)(su)中(zhong)過(guo)電流,減速(su)(su)中(zhong)過(guo)電流,和恒速(su)(su)中(zhong)過(guo)電流,此故障產生的(de)原因主要有以(yi)下幾種:
(1) 加(jia)速時(shi)間過短,這是我們(men)過電流現象(xiang)中最常見的。依據不同的負(fu)載(zai)情況(kuang)我們(men)相(xiang)應地調整加(jia)減速時(shi)間,就能消除(chu)此故(gu)障。
(2) 大(da)功率(lv)晶體(ti)管(guan)的(de)(de)損壞也可(ke)(ke)能(neng)引起OC報警,富士變頻(pin)器(qi)的(de)(de)大(da)功率(lv)晶體(ti)管(guan)隨著(zhu)半導(dao)體(ti)技術(shu)(shu)的(de)(de)發展經過了幾次(ci)換代,從早期的(de)(de)用于G2(P2),G5(P5),G7(P7)系(xi)列(lie)的(de)(de)GTR模塊,到G9(P9)系(xi)列(lie)的(de)(de)IGBT模塊,直到現在使用的(de)(de)IPM模塊,無論從封裝技術(shu)(shu)還(huan)是保護性(xing)能(neng),都有了很大(da)的(de)(de)提高,高耐(nai)壓、大(da)電流、高頻(pin)、低(di)耗、靜音、多保護功能(neng)已(yi)成為大(da)功率(lv)晶體(ti)管(guan)模塊的(de)(de)發展趨(qu)勢。大(da)功率(lv)晶體(ti)管(guan)模塊的(de)(de)損壞主要可(ke)(ke)能(neng)有以下幾種原因造(zao)成:
a) 輸出(chu)負載(zai)發生短路;
b) 負(fu)載過大,大電(dian)流持(chi)續出現;
c) 負載波動很大,導致浪涌電流(liu)過大,都(dou)可能引起OC報警(jing),損壞功率模塊。
(3) 驅(qu)(qu)動大(da)功率晶體管工(gong)作(zuo)的(de)驅(qu)(qu)動電路(lu)(lu)的(de)損壞也是(shi)導致(zhi)過(guo)流報(bao)警的(de)一個原因(yin)。富(fu)士G7S、G9S分別使用(yong)了PC922,PC923兩種光耦作(zuo)為驅(qu)(qu)動電路(lu)(lu)的(de)核心部分,由于內置放(fang)大(da)電路(lu)(lu),線路(lu)(lu)設計簡單,被包括富(fu)士變(bian)頻(pin)器在內的(de)多(duo)家變(bian)頻(pin)器廠家廣泛使用(yong)。驅(qu)(qu)動電路(lu)(lu)損壞表現(xian)出來最常見(jian)的(de)現(xian)象就是(shi)缺相,或三相輸出電壓不平衡。
(4) 檢測電路的(de)損壞(huai)也會導(dao)致變頻器顯示OC報警(jing),檢測電流的(de)霍爾傳感器由于(yu)受(shou)溫度,濕度等環境因數(shu)的(de)影響(xiang),工(gong)作點很容易發生飄移(yi),導(dao)致OC報警(jing)。、
