高壓開關柜是電(dian)力(li)系統中(zhong)不可或缺(que)的一部分，主(zhu)要用于工廠和電(dian)力(li)系統中(zhong)接(jie)受和分配電(dian)能并對電(dian)路實行(xing)控制(zhi)、保護(hu)和監(jian)測，適用范圍廣(guang)泛，比(bi)如建材、冶金、電(dian)力(li)、化工、船(chuan)舶、鐵路、紡織、礦產等(deng)多行(xing)業。如果高壓開關柜發(fa)生(sheng)儲(chu)能障礙，會發(fa)生(sheng)開關無法合閘。因此，工作人員需要及時有效地(di)從以下(xia)幾(ji)個方面進行(xing)檢查和維(wei)護(hu)：

1．控制(zhi)開關故障或(huo)電(dian)路開路

控(kong)(kong)制(zhi)開(kai)(kai)關損壞使電(dian)(dian)(dian)(dian)路(lu)(lu)不(bu)能閉合(he)及(ji)控(kong)(kong)制(zhi)回路(lu)(lu)斷線造成開(kai)(kai)路(lu)(lu)時，故障表(biao)(biao)現(xian)形式都是(shi)電(dian)(dian)(dian)(dian)機(ji)不(bu)轉(zhuan)、電(dian)(dian)(dian)(dian)機(ji)兩端沒有(you)電(dian)(dian)(dian)(dian)壓。查找方法(fa)(fa)是(shi)用萬用表(biao)(biao)測量電(dian)(dian)(dian)(dian)壓或電(dian)(dian)(dian)(dian)阻(zu)。測量電(dian)(dian)(dian)(dian)壓法(fa)(fa)是(shi)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)路(lu)(lu)通(tong)電(dian)(dian)(dian)(dian)情況下，萬用表(biao)(biao)調(diao)到電(dian)(dian)(dian)(dian)壓檔，如果有(you)電(dian)(dian)(dian)(dian)壓(降壓元件除外)被測兩點(dian)間(jian)有(you)開(kai)(kai)路(lu)(lu)點(dian)。用測量電(dian)(dian)(dian)(dian)阻(zu)法(fa)(fa)應(ying)當(dang)注意旁(pang)路(lu)(lu)的通(tong)斷，如果有(you)旁(pang)路(lu)(lu)并聯電(dian)(dian)(dian)(dian)路(lu)(lu)，應(ying)將被測線路(lu)(lu)一端斷開(kai)(kai)。

2．行程開(kai)關(guan)調節不當

行程開(kai)(kai)關(guan)是控(kong)制(zhi)電(dian)機(ji)儲(chu)能(neng)(neng)(neng)位置的(de)限(xian)(xian)位開(kai)(kai)關(guan)。當電(dian)機(ji)儲(chu)能(neng)(neng)(neng)到(dao)位時將電(dian)機(ji)電(dian)源(yuan)切(qie)斷。如(ru)果限(xian)(xian)位過高時，機(ji)構儲(chu)能(neng)(neng)(neng)已滿。故(gu)障(zhang)現象是:電(dian)機(ji)空轉不(bu)停機(ji)、儲(chu)能(neng)(neng)(neng)指示(shi)燈不(bu)亮。只有打開(kai)(kai)控(kong)制(zhi)開(kai)(kai)關(guan)(HK)才能(neng)(neng)(neng)使(shi)電(dian)機(ji)停止。限(xian)(xian)位調節(jie)過低時，電(dian)機(ji)儲(chu)能(neng)(neng)(neng)未(wei)滿提前停機(ji)。由于儲(chu)能(neng)(neng)(neng)不(bu)到(dao)位開(kai)(kai)關(guan)不(bu)能(neng)(neng)(neng)合(he)閘。調節(jie)限(xian)(xian)位的(de)方法是手動慢慢儲(chu)能(neng)(neng)(neng)找到(dao)正確位置，并(bing)且緊(jin)固。

3．電機故障

如果電(dian)機(ji)(ji)繞組燒毀，將有異味、冒煙、保險熔(rong)斷等現象發生。如果電(dian)機(ji)(ji)兩端有電(dian)壓(ya)(ya)，電(dian)機(ji)(ji)不轉。可能(neng)是碳刷脫落或磨損嚴(yan)重等故障(zhang)。判斷是否是電(dian)機(ji)(ji)故障(zhang)的方法(fa)有測(ce)量電(dian)機(ji)(ji)兩端電(dian)壓(ya)(ya)、電(dian)阻(zu)或用(yong)其它好(hao)的電(dian)機(ji)(ji)替換(huan)進行檢查。
