       在處理故障貼片鋁電解電容器(qi)時，應在(zai)斷開貼(tie)片(pian)電解(jie)電容(rong)器(qi)的斷路器(qi)，拉開斷路器(qi)兩則的隔離開關，并對貼(tie)片(pian)電解(jie)電容(rong)器(qi)組經放(fang)電電阻放(fang)電后進行。那么如何(he)處理貼(tie)片(pian)電解(jie)電容(rong)故障問題？以下(xia)幾點(dian)

       1、對于雙(shuang)星形接線的貼(tie)片電(dian)(dian)解電(dian)(dian)容器(qi)組的中性線上(shang)，以及(ji)多個貼(tie)片電(dian)(dian)解電(dian)(dian)容器(qi)的串接線上(shang)，還應單獨(du)進行放電(dian)(dian)。貼(tie)片電(dian)(dian)解電(dian)(dian)容器(qi)在變電(dian)(dian)，濾(lv)波，耦合(he)等(deng)各種(zhong)設備中屬于可(ke)靠性比(bi)較(jiao)薄弱的電(dian)(dian)器(qi)，它比(bi)同級電(dian)(dian)壓的其他設備的絕緣的電(dian)(dian)子元(yuan)器(qi)件較(jiao)為(wei)薄弱，內(nei)部(bu)元(yuan)件發熱較(jiao)多，而散熱情況又欠佳，內(nei)部(bu)故障的機會較(jiao)多，制造(zao)電(dian)(dian)力貼(tie)片電(dian)(dian)解電(dian)(dian)容器(qi)內(nei)部(bu)材料的可(ke)燃物(wu)成分又大，所以運行中極易著火。

       2、貼片電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容器(qi)組經放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)阻(放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)變壓器(qi)或(huo)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓互(hu)感器(qi))放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)以后，由于部分殘(can)存(cun)電(dian)(dian)(dian)(dian)(dian)荷一時(shi)放(fang)(fang)(fang)不盡，仍應(ying)進行一次人(ren)工放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)時(shi)先(xian)將接地(di)線接地(di)端(duan)接好(hao)(hao)，再用接地(di)棒(bang)多次對貼片電(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)容器(qi)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，直至無放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)火花及(ji)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)聲(sheng)為止(zhi)，然后將接地(di)端(duan)固定(ding)好(hao)(hao)。

       3、由于(yu)故(gu)(gu)(gu)障貼片電(dian)(dian)解電(dian)(dian)容(rong)(rong)(rong)器非常可能(neng)發(fa)生引線接觸(chu)不良(liang)、內(nei)部斷(duan)線或熔(rong)絲熔(rong)斷(duan)等，因此有(you)部分電(dian)(dian)荷可能(neng)未放盡，所(suo)以(yi)各種(zhong)檢修(xiu)人員(yuan)在(zai)接觸(chu)故(gu)(gu)(gu)障貼片電(dian)(dian)解電(dian)(dian)容(rong)(rong)(rong)器之前，還(huan)應戴上(shang)絕緣手(shou)套，先(xian)用(yong)短(duan)路(lu)線將故(gu)(gu)(gu)障貼片電(dian)(dian)解電(dian)(dian)容(rong)(rong)(rong)器兩極短(duan)接，然后方動(dong)手(shou)拆卸和(he)更換。
