1、注意五金塑料件振動盤電壓大小要求：

國家標準規定，并聯(lian)電(dian)容器工頻長時(shi)刻過電(dian)壓值zui多(duo)不(bu)超越(yue)1.1倍額定電(dian)壓。關于大(da)中型異(yi)步變(bian)頻振(zhen)動盤考慮到確保必(bi)定的補償效果(guo)，而又會出現較高過電(dian)壓，這時(shi)可選(xuan)用壓敏器件(jian)限制過電(dian)壓。

2、注(zhu)意振動(dong)盤維持電壓(ya)時刻(ke)要求：

關于(yu)需主(zhu)動(dong)投切的(de)變頻振動(dong)盤(pan)，或可逆運(yun)轉(zhuan)的(de)變頻振動(dong)盤(pan)，從(cong)正轉(zhuan)狀(zhuang)(zhuang)態到反轉(zhuan)狀(zhuang)(zhuang)態的(de)過渡時刻內，電(dian)(dian)容(rong)(rong)器(qi)的(de)端(duan)電(dian)(dian)壓(ya)(ya)必(bi)須降到額定峰值(初始值)電(dian)(dian)壓(ya)(ya)的(de)10%以下，不(bu)然由(you)于(yu)自勵磁的(de)添(tian)加，變頻振動(dong)盤(pan)的(de)端(duan)電(dian)(dian)壓(ya)(ya)將升高到不(bu)能允許的(de)程度(du)。當選用主(zhu)動(dong)投切時，投、切時刻間隔(ge)的(de)時限應大于(yu)或等于(yu)電(dian)(dian)容(rong)(rong)器(qi)放電(dian)(dian)時刻。

3、注意振動盤避(bi)免(mian)發作自勵磁和(he)諧振：

為(wei)避免被補償變頻(pin)(pin)振動(dong)盤發作自勵磁的情(qing)況發作，就(jiu)地補償的電(dian)(dian)(dian)容(rong)(rong)器(qi)容(rong)(rong)量選用應盡量不(bu)過補。由(you)于變頻(pin)(pin)振動(dong)盤堵(du)截電(dian)(dian)(dian)源后(hou)，其(qi)轉速(su)不(bu)能當即降為(wei)零(ling)，電(dian)(dian)(dian)容(rong)(rong)器(qi)對變頻(pin)(pin)振動(dong)盤繞(rao)組(zu)放電(dian)(dian)(dian)，使變頻(pin)(pin)電(dian)(dian)(dian)機得到勵磁，有可能造成(cheng)短(duan)時過電(dian)(dian)(dian)壓。
