此外回路損耗也使諧振過電壓受到阻尼和限制。當回路電阻大于一定的數(shù)值時，就不會出現(xiàn)強烈的鐵磁諧振過電壓。3）串聯(lián)諧振電路來說，產(chǎn)生鐵磁諧振過電壓的的必要條件是ω0=1/L0C<；因此鐵磁諧振可在很大的范圍內(nèi)發(fā)生。4）維持諧振振蕩和抵償回路電阻損耗的能量均由工頻電源供給。為使工頻能量轉(zhuǎn)化為其它諧振頻率的能量，其轉(zhuǎn)化過程必須是周期性且有節(jié)律的，即…1/2(1，3…）倍頻率的諧振。5）鐵磁諧振對PT的損壞。電磁諧振（分頻）一般應(yīng)具備如下三個條件。①鐵磁式電壓互感器（PT）的非線性效應(yīng)是產(chǎn)生鐵磁諧振的主要原因。②PT感抗為容抗的100倍以內(nèi)，即參數(shù)匹配在諧振范圍。③要有激發(fā)條件，如PT突然合閘、單相接地突然消失、外界對系統(tǒng)的干擾或系統(tǒng)操作產(chǎn)生的過電壓等。

如果能降低變頻器運行溫度，就延長了變頻器的使用壽命，性能也穩(wěn)定。我們一直忙于變頻器的保養(yǎng)。⑴可以延長變頻器的使用期⑵電器方面我們可以說減少維修率⑶也可以體現(xiàn)公司的管理，公司的形象！我司保養(yǎng)的具體方案如下：變頻器須解體，查看內(nèi)部是否有異常現(xiàn)象.（如：鏍絲松動、焊錫脫落、器件松動、器件燒焦、燒煳現(xiàn)象。）檢查變頻器內(nèi)部易老化器件，如：風(fēng)扇，功率器件，功率電容，及印板老化現(xiàn)象。清理變頻器內(nèi)部粉塵，油污，腐蝕性及導(dǎo)體雜質(zhì)。對主要印板如：主控板，驅(qū)動板，開關(guān)電源板。采用全新品進口電子清潔劑進行噴洗，去除其老化層及導(dǎo)電物質(zhì)。對變頻器主要控制部分進行先進的加膜處理。起到防塵，防老化，防導(dǎo)電物質(zhì)。
