變頻電源安裝調試應注意什么
變(bian)(bian)(bian)頻(pin)電(dian)(dian)(dian)源(yuan)(yuan)安裝調試應(ying)注意什(shen)么變(bian)(bian)(bian)頻(pin)電(dian)(dian)(dian)源(yuan)(yuan)通過AC—DC—AC變(bian)(bian)(bian)換對交流電(dian)(dian)(dian)源(yuan)(yuan)進行變(bian)(bian)(bian)換，輸(shu)出純正弦波(bo)功(gong)率(lv)(lv)。它(ta)是可(ke)變(bian)(bian)(bian)電(dian)(dian)(dian)壓(ya)和(he)頻(pin)率(lv)(lv)的(de)(de)重要設備。無論是家(jia)用(yong)(yong)還是工業(ye)用(yong)(yong)途(tu)的(de)(de)單(dan)相(xiang)(xiang)或三相(xiang)(xiang)交流電(dian)(dian)(dian)壓(ya)，其電(dian)(dian)(dian)壓(ya)和(he)頻(pin)率(lv)(lv)均按國(guo)家(jia)規定有一(yi)定標準。在中國(guo)大陸，單(dan)相(xiang)(xiang)電(dian)(dian)(dian)源(yuan)(yuan)為220V，三相(xiang)(xiang)電(dian)(dian)(dian)源(yuan)(yuan)為380V，頻(pin)率(lv)(lv)為50Hz。在其他國(guo)家(jia)，電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)壓(ya)和(he)頻(pin)率(lv)(lv)可(ke)能不同，例如(ru)美(mei)國(guo)/加拿大的(de)(de)單(dan)相(xiang)(xiang)110V60Hz、三相(xiang)(xiang)480v60Hz等。華源(yuan)(yuan)變(bian)(bian)(bian)頻(pin)電(dian)(dian)(dian)源(yuan)(yuan)靠內部(bu)IGBT
