剖析構成貫穿電容的補償柜
貫穿電容由陶瓷介質、端電級、金屬電級三種材料構成，失效形式為金屬電級和陶介之間層錯，電氣表現為受外力（如輕輕彎曲板子或用烙鐵頭碰一下）和溫度沖擊（如烙鐵焊接）時貫穿電容時好時壞。多層陶瓷貫穿電容器通常具有2大類類足以損害產品靠譜性的基本可見內部缺陷：
電級間失效及結合線破裂(lie)燃燒破裂(lie)。
這(zhe)些缺陷都(dou)會造成(cheng)電流過量，因而損害到組(zu)件的靠譜性，詳細說明(ming)如下(xia)：
1、電級(ji)(ji)間失效及(ji)結合(he)線破裂(lie)主(zhu)要由陶瓷的(de)高空隙，或電介(jie)質層(ceng)(ceng)與(yu)相對電級(ji)(ji)間存在的(de)空隙引起(qi)，使電級(ji)(ji)間是電介(jie)質層(ceng)(ceng)裂(lie)開，成為潛(qian)伏性的(de)漏電危機；
2、燃燒(shao)破裂(lie)(lie)的(de)特性與(yu)電級垂直，且一般(ban)源自電級邊(bian)緣或(huo)終端。假如顯示出(chu)破裂(lie)(lie)是垂直的(de)話，則它們應是由燃燒(shao)所引起；
主要作用(yong)如下：
用于(yu)補償發(fa)電(dian)(dian)(dian)機無(wu)功(gong)電(dian)(dian)(dian)流、減輕發(fa)電(dian)(dian)(dian)機工作負荷，增加發(fa)電(dian)(dian)(dian)機可(ke)使用容量(liang)，可(ke)減少工廠(chang)一定的用電(dian)(dian)(dian)量(liang)、節省工業電(dian)(dian)(dian)力(li)，提高發(fa)供電(dian)(dian)(dian)設備的供電(dian)(dian)(dian)質量(liang)和供電(dian)(dian)(dian)能(neng)力(li)。 用電(dian)(dian)(dian)設備除電(dian)(dian)(dian)阻(zu)性負載外，大(da)部(bu)分用電(dian)(dian)(dian)設備均屬感(gan)性用電(dian)(dian)(dian)負載（如日光燈、變(bian)壓(ya)器、馬達(da)等用電(dian)(dian)(dian)設備）這些感(gan)應負載，使供電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)相位發(fa)生改變(bian)（即電(dian)(dian)(dian)流滯(zhi)后于(yu)電(dian)(dian)(dian)壓(ya)），因此電(dian)(dian)(dian)壓(ya)波(bo)動大(da)，無(wu)功(gong)功(gong)率增大(da)，浪費大(da)量(liang)電(dian)(dian)(dian)能(neng)。
當功(gong)率因(yin)數過低(di)時，以(yi)致供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源輸出(chu)電(dian)(dian)(dian)(dian)(dian)流過大而出(chu)現(xian)負載現(xian)象。貫穿電(dian)(dian)(dian)(dian)(dian)容補償(chang)柜內的電(dian)(dian)(dian)(dian)(dian)腦貫穿電(dian)(dian)(dian)(dian)(dian)容控制系(xi)統(tong)可解決以(yi)上弊端，它可根(gen)據用電(dian)(dian)(dian)(dian)(dian)負荷的變化，而自動(dong)設置貫穿電(dian)(dian)(dian)(dian)(dian)容組數的投入(ru)，進(jin)行電(dian)(dian)(dian)(dian)(dian)流補償(chang)，從而減低(di)大量無功(gong)電(dian)(dian)(dian)(dian)(dian)流，使線路(lu)電(dian)(dian)(dian)(dian)(dian)能損耗(hao)降到較低(di)程度，提(ti)供(gong)一個高素質的電(dian)(dian)(dian)(dian)(dian)力(li)源。 在工(gong)(gong)業生產中廣泛使用的交流異步電(dian)(dian)(dian)(dian)(dian)動(dong)機，電(dian)(dian)(dian)(dian)(dian)焊機、電(dian)(dian)(dian)(dian)(dian)磁(ci)鐵工(gong)(gong)頻(pin)加熱器導用點設備(bei)都是感性負載。
