1、注意五金塑料件振動盤電壓大小要求：

國(guo)家標準(zhun)規定(ding)，并(bing)聯電(dian)(dian)容器工頻長(chang)時刻過(guo)電(dian)(dian)壓(ya)(ya)值zui多不超(chao)越1.1倍額定(ding)電(dian)(dian)壓(ya)(ya)。關于大(da)中(zhong)型(xing)異步變頻振動盤考慮(lv)到確保必定(ding)的補償效(xiao)果(guo)，而又(you)會(hui)出現較高(gao)過(guo)電(dian)(dian)壓(ya)(ya)，這時可選(xuan)用壓(ya)(ya)敏器件限制(zhi)過(guo)電(dian)(dian)壓(ya)(ya)。

2、注(zhu)意振動(dong)盤維(wei)持電(dian)壓時刻要求：

關于需主動(dong)投(tou)切的(de)變頻(pin)振(zhen)動(dong)盤(pan)，或可(ke)逆運轉的(de)變頻(pin)振(zhen)動(dong)盤(pan)，從正轉狀(zhuang)態到反轉狀(zhuang)態的(de)過渡時刻內，電(dian)(dian)容器(qi)的(de)端電(dian)(dian)壓(ya)必須(xu)降(jiang)到額定峰值(初始(shi)值)電(dian)(dian)壓(ya)的(de)10%以下，不(bu)然由于自勵磁(ci)的(de)添加，變頻(pin)振(zhen)動(dong)盤(pan)的(de)端電(dian)(dian)壓(ya)將升高到不(bu)能(neng)允許的(de)程度。當(dang)選(xuan)用主動(dong)投(tou)切時，投(tou)、切時刻間隔的(de)時限應大于或等于電(dian)(dian)容器(qi)放電(dian)(dian)時刻。

3、注意振動(dong)盤避免(mian)發(fa)作自勵磁和諧振：

為避免被(bei)補償變(bian)頻(pin)振(zhen)動(dong)(dong)盤(pan)發(fa)作自勵磁的情況發(fa)作，就地補償的電(dian)(dian)容器(qi)容量(liang)選用應盡量(liang)不(bu)過補。由于(yu)變(bian)頻(pin)振(zhen)動(dong)(dong)盤(pan)堵截電(dian)(dian)源(yuan)后，其(qi)轉速不(bu)能(neng)當即降為零，電(dian)(dian)容器(qi)對(dui)變(bian)頻(pin)振(zhen)動(dong)(dong)盤(pan)繞組放電(dian)(dian)，使變(bian)頻(pin)電(dian)(dian)機得(de)到勵磁，有可(ke)能(neng)造成短時過電(dian)(dian)壓。
