1、注意五金塑料件振動盤電壓大小要求(qiu)：

國家標準規定，并聯電(dian)(dian)容器工頻長時刻過電(dian)(dian)壓(ya)值zui多不(bu)超越(yue)1.1倍額定電(dian)(dian)壓(ya)。關于大(da)中(zhong)型異(yi)步變頻振動盤考慮(lv)到確保(bao)必定的補(bu)償(chang)效(xiao)果，而又(you)會出(chu)現(xian)較高過電(dian)(dian)壓(ya)，這時可(ke)選(xuan)用壓(ya)敏器件限制過電(dian)(dian)壓(ya)。

2、注意振動(dong)盤維持(chi)電壓時刻要求：

關于(yu)需主動(dong)(dong)投切(qie)的變(bian)頻振(zhen)(zhen)動(dong)(dong)盤(pan)，或(huo)可逆(ni)運轉(zhuan)(zhuan)的變(bian)頻振(zhen)(zhen)動(dong)(dong)盤(pan)，從(cong)正轉(zhuan)(zhuan)狀(zhuang)態到反(fan)轉(zhuan)(zhuan)狀(zhuang)態的過渡時刻(ke)內，電(dian)(dian)容(rong)器(qi)的端(duan)電(dian)(dian)壓(ya)必須降到額定峰值(初始值)電(dian)(dian)壓(ya)的10%以下，不然由于(yu)自勵磁的添加，變(bian)頻振(zhen)(zhen)動(dong)(dong)盤(pan)的端(duan)電(dian)(dian)壓(ya)將升高到不能(neng)允許的程(cheng)度。當選用主動(dong)(dong)投切(qie)時，投、切(qie)時刻(ke)間隔的時限應大于(yu)或(huo)等于(yu)電(dian)(dian)容(rong)器(qi)放電(dian)(dian)時刻(ke)。

3、注意振動盤避免(mian)發(fa)作(zuo)自勵磁和(he)諧(xie)振：

為(wei)避免(mian)被(bei)補(bu)(bu)償變(bian)頻(pin)振(zhen)動(dong)盤(pan)(pan)發作自勵磁(ci)的情況(kuang)發作，就(jiu)地補(bu)(bu)償的電(dian)(dian)容(rong)器(qi)容(rong)量(liang)(liang)選用應盡(jin)量(liang)(liang)不(bu)過(guo)補(bu)(bu)。由于(yu)變(bian)頻(pin)振(zhen)動(dong)盤(pan)(pan)堵截(jie)電(dian)(dian)源后，其轉(zhuan)速(su)不(bu)能當(dang)即降(jiang)為(wei)零，電(dian)(dian)容(rong)器(qi)對(dui)變(bian)頻(pin)振(zhen)動(dong)盤(pan)(pan)繞組放電(dian)(dian)，使(shi)變(bian)頻(pin)電(dian)(dian)機得(de)到勵磁(ci)，有可能造成短時過(guo)電(dian)(dian)壓。
