電(dian)(dian)動機使用工頻電(dian)(dian)源驅動時，電(dian)(dian)壓(ya)下(xia)降(jiang)則電(dian)(dian)流(liu)增(zeng)(zeng)加(jia);對于變頻器驅動，如果頻率下(xia)降(jiang)時電(dian)(dian)壓(ya)也下(xia)降(jiang)，那么電(dian)(dian)流(liu)是否增(zeng)(zeng)加(jia)?

　　鋼鐵廠西門子調速器6RA70開機報警F030修理頻率(lv)下降(低速)時,如果輸出相(xiang)同(tong)的功率(lv),則(ze)電流(liu)增加，但在轉矩規定的條件(jian)下,電流(liu)幾乎不(bu)變。

　　采用變頻器運轉(zhuan)時，電機的(de)起動電流(liu)、起動轉(zhuan)矩怎(zen)樣?

　　采(cai)用變(bian)頻(pin)(pin)器運轉(zhuan)，隨著電(dian)機的加速(su)相應提高頻(pin)(pin)率和電(dian)壓(ya)，起(qi)動(dong)電(dian)流(liu)被限制在(zai)150%額定(ding)(ding)電(dian)流(liu)以(yi)(yi)下(根據機種不(bu)同，為(wei)(wei)125%～200%)。用工頻(pin)(pin)電(dian)源直接起(qi)動(dong)時，起(qi)動(dong)電(dian)流(liu)為(wei)(wei)6～7倍，因(yin)此(ci)，將產生(sheng)機械電(dian)氣上的沖(chong)擊。采(cai)用變(bian)頻(pin)(pin)器傳動(dong)可(ke)以(yi)(yi)平滑地起(qi)動(dong)(起(qi)動(dong)時間變(bian)長)。起(qi)動(dong)電(dian)流(liu)為(wei)(wei)額定(ding)(ding)電(dian)流(liu)的1.2～1.5倍，起(qi)動(dong)轉(zhuan)矩為(wei)(wei)70%～120%額定(ding)(ding)轉(zhuan)矩;對(dui)于帶有(you)轉(zhuan)矩自(zi)動(dong)增強功能的變(bian)頻(pin)(pin)器，起(qi)動(dong)轉(zhuan)矩為(wei)(wei)100%以(yi)(yi)上，可(ke)以(yi)(yi)帶全負載起(qi)動(dong)
