純電容濾波補償(chang)模組補償(chang)原理與優缺點

在諧(xie)(xie)(xie)波(bo)(bo)電壓作用下(xia)，電容器(qi)會產生(sheng)額外(wai)的功率損(sun)耗，加快絕緣介(jie)質(zhi)的老化(hua)。更為嚴重的是，大量諧(xie)(xie)(xie)波(bo)(bo)電流很可能引發電容器(qi)和系統其他元件之間的并聯(lian)諧(xie)(xie)(xie)振或串(chuan)聯(lian)諧(xie)(xie)(xie)振，造成電容器(qi)超載而(er)損(sun)壞(huai)。如果對智能建筑配(pei)電回路(lu)(lu)(lu)(lu)的諧(xie)(xie)(xie)波(bo)(bo)進行治理的話，稍有不當(dang)就(jiu)會使(shi)斷(duan)路(lu)(lu)(lu)(lu)器(qi)遮(zhe)斷(duan)能力降低，而(er)且(qie)還會導(dao)致斷(duan)路(lu)(lu)(lu)(lu)器(qi)損(sun)壞(huai)。除此(ci)之外(wai)，感應電動機(ji)的額外(wai)損(sun)耗、電力電纜和配(pei)電線(xian)路(lu)(lu)(lu)(lu)集(ji)膚(fu)效(xiao)應的出現也都是諧(xie)(xie)(xie)波(bo)(bo)惹(re)的禍。

一旦(dan)出(chu)現以(yi)上(shang)幾(ji)種(zhong)出(chu)現放(fang)電(dian)(dian)(dian)聲(sheng)狀況，應針(zhen)對每種(zhong)情況做出(chu)處(chu)(chu)理(li)(li)，即其處(chu)(chu)理(li)(li)方法依次為：將電(dian)(dian)(dian)容(rong)器(qi)(qi)停(ting)運并放(fang)電(dian)(dian)(dian)后把外套管卸出(chu)，擦干重新裝好(hao)；添加(jia)同種(zhong)規格的(de)電(dian)(dian)(dian)容(rong)器(qi)(qi)油(you)；如放(fang)電(dian)(dian)(dian)聲(sheng)不止(zhi)，應拆(chai)開修理(li)(li)；將電(dian)(dian)(dian)容(rong)器(qi)(qi)停(ting)運并放(fang)電(dian)(dian)(dian)后進行處(chu)(chu)理(li)(li)，使其芯(xin)子和外殼接觸(chu)好(hao)。
