1、注意五金塑料件振動盤電壓大小要求(qiu)：

國家標準(zhun)規定(ding)，并聯電(dian)容器(qi)工頻長時刻過(guo)電(dian)壓值zui多(duo)不超越1.1倍額定(ding)電(dian)壓。關于大(da)中型異步變頻振動盤考慮到(dao)確保必定(ding)的補償效果，而又會出現(xian)較高過(guo)電(dian)壓，這時可選用壓敏器(qi)件限制(zhi)過(guo)電(dian)壓。

2、注意(yi)振動(dong)盤維持(chi)電壓(ya)時刻要(yao)求：

關于需(xu)主(zhu)動(dong)投(tou)(tou)切(qie)的(de)(de)(de)變(bian)頻振動(dong)盤，或(huo)可逆運轉的(de)(de)(de)變(bian)頻振動(dong)盤，從正轉狀態到反轉狀態的(de)(de)(de)過渡時(shi)刻內，電(dian)(dian)容器的(de)(de)(de)端(duan)電(dian)(dian)壓(ya)必須(xu)降到額定峰值(初始(shi)值)電(dian)(dian)壓(ya)的(de)(de)(de)10%以下(xia)，不然由于自勵(li)磁的(de)(de)(de)添(tian)加，變(bian)頻振動(dong)盤的(de)(de)(de)端(duan)電(dian)(dian)壓(ya)將升高到不能允(yun)許的(de)(de)(de)程度。當選用(yong)主(zhu)動(dong)投(tou)(tou)切(qie)時(shi)，投(tou)(tou)、切(qie)時(shi)刻間隔(ge)的(de)(de)(de)時(shi)限應(ying)大于或(huo)等于電(dian)(dian)容器放電(dian)(dian)時(shi)刻。

3、注意振(zhen)動(dong)盤避免發作自勵磁和諧(xie)振(zhen)：

為避免被補償變頻振(zhen)動(dong)盤(pan)(pan)發作自勵(li)磁的(de)情(qing)況(kuang)發作，就地補償的(de)電(dian)(dian)(dian)容(rong)器容(rong)量選(xuan)用應(ying)盡(jin)量不過(guo)補。由于變頻振(zhen)動(dong)盤(pan)(pan)堵截電(dian)(dian)(dian)源(yuan)后，其轉速(su)不能當(dang)即降為零，電(dian)(dian)(dian)容(rong)器對變頻振(zhen)動(dong)盤(pan)(pan)繞組放電(dian)(dian)(dian)，使變頻電(dian)(dian)(dian)機得(de)到勵(li)磁，有可能造成短時(shi)過(guo)電(dian)(dian)(dian)壓。
