山西高壓開關柜發生儲能故障怎么辦？山西景泰電氣配電柜為您解答

當高壓(ya)(ya)開(kai)關柜發(fa)生(sheng)儲能故(gu)障的時，高壓(ya)(ya)開(kai)光柜不(bu)(bu)能合閘(zha)，不(bu)(bu)正常(chang)配(pei)送電源，工廠機器不(bu)(bu)能運行(xing)。所以，高壓(ya)(ya)開(kai)關柜發(fa)生(sheng)儲能故(gu)障是個非(fei)常(chang)大的故(gu)障。很多業(ye)主非(fei)常(chang)害怕(pa)高壓(ya)(ya)開(kai)關柜發(fa)生(sheng)儲能故(gu)障。

1．控制(zhi)開關故(gu)障或電(dian)路開路

控(kong)制開(kai)(kai)關(guan)損(sun)壞使電(dian)(dian)(dian)(dian)路(lu)(lu)不(bu)能閉合(he)及控(kong)制回(hui)路(lu)(lu)斷線造成開(kai)(kai)路(lu)(lu)時，故障表現形式都是電(dian)(dian)(dian)(dian)機(ji)不(bu)轉、電(dian)(dian)(dian)(dian)機(ji)兩端沒有(you)(you)電(dian)(dian)(dian)(dian)壓(ya)。查找方法是用萬(wan)用表測(ce)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)壓(ya)或電(dian)(dian)(dian)(dian)阻(zu)。測(ce)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)壓(ya)法是控(kong)制電(dian)(dian)(dian)(dian)路(lu)(lu)通(tong)電(dian)(dian)(dian)(dian)情況(kuang)下，萬(wan)用表調(diao)到電(dian)(dian)(dian)(dian)壓(ya)檔，如(ru)果有(you)(you)電(dian)(dian)(dian)(dian)壓(ya)(降壓(ya)元(yuan)件除(chu)外)被測(ce)兩點(dian)間有(you)(you)開(kai)(kai)路(lu)(lu)點(dian)。用測(ce)量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)阻(zu)法應(ying)當注(zhu)意旁路(lu)(lu)的(de)通(tong)斷，如(ru)果有(you)(you)旁路(lu)(lu)并聯電(dian)(dian)(dian)(dian)路(lu)(lu)，應(ying)將(jiang)被測(ce)線路(lu)(lu)一(yi)端斷開(kai)(kai)。

2．行程開(kai)關調節不當

行(xing)程開(kai)(kai)(kai)關(guan)是控制電(dian)(dian)(dian)機(ji)(ji)儲(chu)(chu)能(neng)位(wei)(wei)置的限位(wei)(wei)開(kai)(kai)(kai)關(guan)。當電(dian)(dian)(dian)機(ji)(ji)儲(chu)(chu)能(neng)到位(wei)(wei)時(shi)將(jiang)電(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)源(yuan)切斷。如果限位(wei)(wei)過高時(shi)，機(ji)(ji)構儲(chu)(chu)能(neng)已滿(man)。故(gu)障現象是:電(dian)(dian)(dian)機(ji)(ji)空轉不(bu)(bu)停機(ji)(ji)、儲(chu)(chu)能(neng)指示(shi)燈不(bu)(bu)亮。只有打開(kai)(kai)(kai)控制開(kai)(kai)(kai)關(guan)(HK)才能(neng)使電(dian)(dian)(dian)機(ji)(ji)停止。限位(wei)(wei)調節過低時(shi)，電(dian)(dian)(dian)機(ji)(ji)儲(chu)(chu)能(neng)未滿(man)提前停機(ji)(ji)。由(you)于儲(chu)(chu)能(neng)不(bu)(bu)到位(wei)(wei)開(kai)(kai)(kai)關(guan)不(bu)(bu)能(neng)合閘。調節限位(wei)(wei)的方法是手動慢(man)慢(man)儲(chu)(chu)能(neng)找到正確位(wei)(wei)置，并且緊固(gu)。

3．電機(ji)故障

如(ru)果(guo)電(dian)(dian)機繞組燒(shao)毀，將有(you)(you)異味、冒煙、保險熔斷等(deng)現(xian)象發生(sheng)。如(ru)果(guo)電(dian)(dian)機兩(liang)端有(you)(you)電(dian)(dian)壓，電(dian)(dian)機不(bu)轉。可能是碳刷脫(tuo)落或磨損(sun)嚴重等(deng)故(gu)障。判斷是否是電(dian)(dian)機故(gu)障的方(fang)法有(you)(you)測量電(dian)(dian)機兩(liang)端電(dian)(dian)壓、電(dian)(dian)阻或用其它(ta)好的電(dian)(dian)機替換進行(xing)檢查。

高壓(ya)開關柜的(de)控制(zhi)開關損(sun)壞(huai)，就會(hui)使電路(lu)不能閉(bi)合；當它控制(zhi)回(hui)路(lu)斷線造成開路(lu)時，故障(zhang)表(biao)現形式都是(shi)電機不轉、電機兩端沒有(you)電壓(ya)。這類故障(zhang)可以(yi)用萬用表(biao)測量電壓(ya)或電阻。測量電壓(ya)法是(shi)控制(zhi)電路(lu)通電情況下，萬用表(biao)調到電壓(ya)檔，如果(guo)有(you)電壓(ya)被測兩點(dian)間有(you)開路(lu)點(dian)。

行程開關是高壓(ya)開關柜中控制(zhi)電(dian)(dian)(dian)(dian)機(ji)儲(chu)(chu)能(neng)位置(zhi)的限位開關，當(dang)電(dian)(dian)(dian)(dian)機(ji)儲(chu)(chu)能(neng)到位時(shi)將電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)源切斷；如果限位過高時(shi)，機(ji)構儲(chu)(chu)能(neng)已滿(man)。這方面出現故(gu)障的主要表象是電(dian)(dian)(dian)(dian)機(ji)空轉不停機(ji)、儲(chu)(chu)能(neng)指示燈(deng)不亮，只有打開控制(zhi)開關才(cai)能(neng)使電(dian)(dian)(dian)(dian)機(ji)停止(zhi)；限位調節過低時(shi)，電(dian)(dian)(dian)(dian)機(ji)儲(chu)(chu)能(neng)未滿(man)提(ti)前停機(ji)。

由(you)于儲能不到位(wei)開(kai)關(guan)不能合閘，調節限位(wei)的方法(fa)是手動慢慢儲能找到正確位(wei)置(zhi)，并且(qie)緊(jin)固，從而使得高壓開(kai)關(guan)柜的行程開(kai)關(guan)恢復正常，并且(qie)起到制電機儲能位(wei)置(zhi)的作用。

如果高(gao)壓開關柜的(de)電(dian)(dian)(dian)機(ji)(ji)繞組燒毀，就會有(you)異味(wei)、冒煙、保險熔斷等(deng)現(xian)象發生，如果電(dian)(dian)(dian)機(ji)(ji)兩端有(you)電(dian)(dian)(dian)壓，電(dian)(dian)(dian)機(ji)(ji)不轉，可能是碳(tan)刷脫落或磨損嚴重等(deng)故(gu)障。判(pan)斷是否是電(dian)(dian)(dian)機(ji)(ji)故(gu)障的(de)方法(fa)有(you)測量電(dian)(dian)(dian)機(ji)(ji)兩端電(dian)(dian)(dian)壓、電(dian)(dian)(dian)阻或用(yong)其它好的(de)電(dian)(dian)(dian)機(ji)(ji)替換進行檢查。
