1、注意五金塑料件振動盤電壓大小要求：

國家標準規定(ding)，并(bing)聯電(dian)容器工頻長時刻過電(dian)壓(ya)(ya)值zui多不超越1.1倍(bei)額(e)定(ding)電(dian)壓(ya)(ya)。關于大中型異步變頻振動盤考慮(lv)到確保(bao)必定(ding)的補償效果(guo)，而又會出現較高過電(dian)壓(ya)(ya)，這時可選用壓(ya)(ya)敏器件限制(zhi)過電(dian)壓(ya)(ya)。

2、注(zhu)意振動盤維持電壓(ya)時刻要求：

關(guan)于需主動(dong)(dong)投切(qie)的(de)變頻(pin)振動(dong)(dong)盤(pan)，或可逆運轉的(de)變頻(pin)振動(dong)(dong)盤(pan)，從正轉狀態到(dao)反轉狀態的(de)過渡時(shi)(shi)刻內(nei)，電(dian)容(rong)器(qi)的(de)端電(dian)壓(ya)必須降到(dao)額定峰值(初始值)電(dian)壓(ya)的(de)10%以下(xia)，不(bu)然由于自勵磁的(de)添加(jia)，變頻(pin)振動(dong)(dong)盤(pan)的(de)端電(dian)壓(ya)將升(sheng)高(gao)到(dao)不(bu)能允許(xu)的(de)程度。當選用主動(dong)(dong)投切(qie)時(shi)(shi)，投、切(qie)時(shi)(shi)刻間隔的(de)時(shi)(shi)限應(ying)大于或等于電(dian)容(rong)器(qi)放電(dian)時(shi)(shi)刻。

3、注意振(zhen)動盤避免發作自勵磁和諧振(zhen)：

為避免(mian)被補償(chang)變頻(pin)(pin)振(zhen)(zhen)動(dong)(dong)盤(pan)(pan)發作(zuo)自勵磁的(de)情況發作(zuo)，就地(di)補償(chang)的(de)電(dian)(dian)(dian)(dian)(dian)容器容量(liang)選用應盡量(liang)不(bu)過補。由于變頻(pin)(pin)振(zhen)(zhen)動(dong)(dong)盤(pan)(pan)堵截電(dian)(dian)(dian)(dian)(dian)源(yuan)后(hou)，其轉速不(bu)能當即降為零，電(dian)(dian)(dian)(dian)(dian)容器對變頻(pin)(pin)振(zhen)(zhen)動(dong)(dong)盤(pan)(pan)繞組(zu)放(fang)電(dian)(dian)(dian)(dian)(dian)，使變頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)機得到勵磁，有可能造成短時過電(dian)(dian)(dian)(dian)(dian)壓(ya)。
