變頻器過電流故障檢查步䠫
1、檢(jian)查(zha)電(dian)機(ji)過(guo)載(zai)對(dui)變(bian)頻(pin)器(qi)過(guo)電(dian)流(liu)故(gu)障(zhang)的(de)影(ying)響(xiang)，變(bian)頻(pin)器(qi)在(zai)運(yun)行(xing)時(shi)電(dian)機(ji)過(guo)載(zai)，工(gong)作(zuo)電(dian)流(liu)會(hui)大(da)於(yu)限(xian)定(ding)的(de)電(dian)流(liu)，短(duan)時(shi)間(jian)的(de)過(guo)載(zai)是(shi)沒(mei)有(you)問(wen)題(ti)的(de)，但(dan)是(shi)長(chang)時(shi)間(jian)的(de)過(guo)載(zai)電(dian)流(liu)增(zeng)大(da)這(zhe)時(shi)會(hui)造(zao)成(cheng)機(ji)器(qi)過(guo)電(dian)流(liu)故(gu)障(zhang) ，嚴重時還會造成更大的故障，因此一定要及時的處理電機過載問題。
2、檢jian查zha變bian頻pin器qi的de電dian源yuan電dian壓ya輸shu入ru是shi否fou正zheng常chang，變bian頻pin器qi電dian源yuan電dian壓ya輸shu入ru出chu現xian不bu正zheng常chang時shi容rong易yi造zao成cheng機ji器qi故gu障zhang，電dian壓ya過guo高gao或huo是shi過guo低di也ye是shi會hui引yin起qi線xian路lu電dian壓ya偏pian低di或huo是shi偏pian高gao對dui機ji器qi造zao成cheng危wei害hai，如ru有you問wen題ti及ji時shi調tiao整zheng輸shu入ru電dian源yuan參can數shu。
3、檢jian查zha變bian頻pin器qi內nei部bu器qi件jian的de損sun壞huai造zao成cheng的de過guo電dian流liu故gu障zhang，在zai檢jian查zha變bian頻pin器qi過guo電dian流liu故gu障zhang時shi內nei部bu的de器qi件jian是shi一yi定ding要yao檢jian查zha的de，如ru開kai關guan短duan路lu，因yin線xian路lu短duan路lu，斷duan路lu，或huo是shi電dian路lu板ban短duan路lu，等deng有you時shi很hen小xiao有you一yi個ge問wen題ti也ye是shi會hui引yin起qi機ji器qi的de故gu障zhang問wen題ti。
