真(zhen)空(kong)熔(rong)煉爐(lu)常見的故(gu)(gu)障(zhang)(zhang)及處理方式 真(zhen)空(kong)熔(rong)煉爐(lu)在(zai)(zai)使(shi)用長時間后會出現(xian)(xian)一(yi)些故(gu)(gu)障(zhang)(zhang),這是(shi)(shi)(shi)在(zai)(zai)所難免的。今天(tian)八佳小編就(jiu)和大(da)家說(shuo)說(shuo)當故(gu)(gu)障(zhang)(zhang)出現(xian)(xian),要做哪些處理方法。 1、故(gu)(gu)障(zhang)(zhang)現(xian)(xian)象:真(zhen)空(kong)熔(rong)煉爐(lu)運行正常,但(dan)在(zai)(zai)正常過(guo)流(liu)保護(hu)動作時燒毀較多(duo)(duo)的是(shi)(shi)(shi)KP晶(jing)閘(zha)管(guan)和快熔(rong)。 分析(xi)處理:過(guo)流(liu)保護(hu)時為(wei)了(le)向(xiang)電(dian)(dian)(dian)(dian)網釋放平(ping)波電(dian)(dian)(dian)(dian)抗器(qi)的能(neng)量,整流(liu)橋由整流(liu)狀態轉(zhuan)到逆變狀態,這時如果α>120度;,就(jiu)有可能(neng)造成(cheng)(cheng)有源(yuan)逆變顛(dian)(dian)覆,燒毀多(duo)(duo)只晶(jing)閘(zha)管(guan)和快熔(rong),開關跳伴隨有巨大(da)的電(dian)(dian)(dian)(dian)流(liu)短路爆炸聲,對變壓(ya)器(qi)產生較大(da)的電(dian)(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)(dian)磁力(li)沖(chong)擊,嚴重時會損壞變亞(ya)器(qi)。 2、故(gu)(gu)障(zhang)(zhang)現(xian)(xian)象:真(zhen)空(kong)熔(rong)煉爐(lu)運行正常,但(dan)在(zai)(zai)高(gao)電(dian)(dian)(dian)(dian)壓(ya)區內某(mou)點附近設(she)備(bei)工作不穩定(ding),直流(liu)電(dian)(dian)(dian)(dian)壓(ya)表晃動,設(she)備(bei)伴隨有吱吱的聲音,這種(zhong)情況極容易(yi)造成(cheng)(cheng)逆變橋顛(dian)(dian)覆燒毀晶(jing)閘(zha)管(guan)。 分析(xi)處理:這種(zhong)故(gu)(gu)障(zhang)(zhang)較難排除,多(duo)(duo)發生于設(she)備(bei)的某(mou)部(bu)件(jian)高(gao)壓(ya)打(da)(da)(da)(da)火(huo)(huo): (1)真(zhen)空(kong)熔(rong)煉爐(lu)的連(lian)接(jie)(jie)銅(tong)排接(jie)(jie)頭螺絲(si)松(song)動造成(cheng)(cheng)打(da)(da)(da)(da)火(huo)(huo) (2)斷(duan)路器(qi)主接(jie)(jie)頭氧化導致打(da)(da)(da)(da)火(huo)(huo); (3)補償電(dian)(dian)(dian)(dian)容接(jie)(jie)線(xian)樁螺絲(si)松(song)動,引(yin)起(qi)打(da)(da)(da)(da)火(huo)(huo),補償電(dian)(dian)(dian)(dian)容內部(bu)放電(dian)(dian)(dian)(dian)阻容吸收電(dian)(dian)(dian)(dian)打(da)(da)(da)(da)火(huo)(huo); (4)水冷散熱器(qi)絕緣部(bu)分太臟或炭化對地打(da)(da)(da)(da)火(huo)(huo); (5)真(zhen)空(kong)熔(rong)煉爐(lu)爐(lu)體感應(ying)線(xian)圈(quan)對爐(lu)殼(ke)/爐(lu)底(di)板打(da)(da)(da)(da)火(huo)(huo),爐(lu)體感應(ying)線(xian)圈(quan)匝(za)間距太近,匝(za)間打(da)(da)(da)(da)火(huo)(huo)或起(qi)弧。固定(ding)爐(lu)體感應(ying)線(xian)圈(quan)的絕緣柱因高(gao)溫炭化放電(dian)(dian)(dian)(dian)打(da)(da)(da)(da)火(huo)(huo) (6)晶(jing)閘(zha)管(guan)內部(bu)打(da)(da)(da)(da)火(huo)(huo)。 以上就(jiu)是(shi)(shi)(shi)真(zhen)空(kong)熔(rong)煉爐(lu)廠家分析(xi)的兩(liang)種(zhong)常見的故(gu)(gu)障(zhang)(zhang)。大(da)家明白了(le)嗎?如果還有不明白,也可以打(da)(da)(da)(da)電(dian)(dian)(dian)(dian)話(hua)咨詢(xun)。
