1、注意五金塑料件振動盤電壓大(da)小要(yao)求：

國家(jia)標準規定(ding)，并聯電(dian)(dian)容器(qi)工(gong)頻長時刻過電(dian)(dian)壓值zui多(duo)不(bu)超越(yue)1.1倍額定(ding)電(dian)(dian)壓。關于大中型異步(bu)變頻振動盤(pan)考慮到確保必定(ding)的(de)補(bu)償效(xiao)果，而又會出現較高過電(dian)(dian)壓，這(zhe)時可(ke)選用壓敏器(qi)件限制過電(dian)(dian)壓。

2、注意振動(dong)盤維持(chi)電壓時刻要求：

關于需主動(dong)投切(qie)的(de)變頻振(zhen)動(dong)盤，或可逆運轉(zhuan)的(de)變頻振(zhen)動(dong)盤，從正轉(zhuan)狀態到反轉(zhuan)狀態的(de)過渡時刻內，電(dian)(dian)容(rong)(rong)器的(de)端(duan)電(dian)(dian)壓必須(xu)降到額定峰值(zhi)(初(chu)始值(zhi))電(dian)(dian)壓的(de)10%以下，不然由(you)于自勵(li)磁的(de)添加，變頻振(zhen)動(dong)盤的(de)端(duan)電(dian)(dian)壓將升高到不能允許的(de)程度。當選用主動(dong)投切(qie)時，投、切(qie)時刻間隔的(de)時限(xian)應大于或等于電(dian)(dian)容(rong)(rong)器放電(dian)(dian)時刻。

3、注意振動(dong)盤避免(mian)發作(zuo)自勵(li)磁和諧振：

為避免(mian)被補(bu)償變(bian)頻振動(dong)(dong)盤發作自勵磁的情況發作，就地補(bu)償的電(dian)容(rong)器(qi)容(rong)量選(xuan)用(yong)應盡量不過(guo)補(bu)。由(you)于(yu)變(bian)頻振動(dong)(dong)盤堵(du)截電(dian)源后，其轉(zhuan)速(su)不能當即降為零，電(dian)容(rong)器(qi)對變(bian)頻振動(dong)(dong)盤繞組放電(dian)，使變(bian)頻電(dian)機得到勵磁，有(you)可能造(zao)成短時過(guo)電(dian)壓。
