1、注意五金塑料件振動盤電壓大小要(yao)求：

國家標準(zhun)規(gui)定(ding)，并(bing)聯電(dian)(dian)容(rong)器工頻長時刻(ke)過電(dian)(dian)壓(ya)(ya)值zui多(duo)不超越1.1倍(bei)額定(ding)電(dian)(dian)壓(ya)(ya)。關(guan)于(yu)大中型異步變頻振動盤考慮到確保必定(ding)的補(bu)償(chang)效果，而又會出現較高過電(dian)(dian)壓(ya)(ya)，這時可選用壓(ya)(ya)敏器件限制過電(dian)(dian)壓(ya)(ya)。

2、注意振動(dong)盤維持電(dian)壓時刻(ke)要求：

關于(yu)(yu)需(xu)主(zhu)動(dong)投切(qie)的變頻振動(dong)盤，或可逆運(yun)轉(zhuan)的變頻振動(dong)盤，從正(zheng)轉(zhuan)狀態(tai)到反(fan)轉(zhuan)狀態(tai)的過(guo)渡時刻(ke)內，電(dian)(dian)(dian)容器的端電(dian)(dian)(dian)壓必須降到額定(ding)峰值(初始值)電(dian)(dian)(dian)壓的10%以下，不然由于(yu)(yu)自(zi)勵磁的添加，變頻振動(dong)盤的端電(dian)(dian)(dian)壓將(jiang)升(sheng)高到不能允許的程(cheng)度。當選用主(zhu)動(dong)投切(qie)時，投、切(qie)時刻(ke)間隔的時限(xian)應(ying)大于(yu)(yu)或等于(yu)(yu)電(dian)(dian)(dian)容器放電(dian)(dian)(dian)時刻(ke)。

3、注意(yi)振動盤避免發作自勵磁和(he)諧振：

為(wei)避(bi)免被補(bu)償變頻(pin)(pin)振(zhen)動(dong)盤(pan)發作(zuo)自勵(li)磁的情況發作(zuo)，就地補(bu)償的電容(rong)(rong)器容(rong)(rong)量選用應(ying)盡量不過(guo)補(bu)。由于變頻(pin)(pin)振(zhen)動(dong)盤(pan)堵截電源后(hou)，其轉速不能當即降(jiang)為(wei)零(ling)，電容(rong)(rong)器對變頻(pin)(pin)振(zhen)動(dong)盤(pan)繞組放(fang)電，使(shi)變頻(pin)(pin)電機得到勵(li)磁，有可能造成短時過(guo)電壓。
