真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)常(chang)見的(de)(de)故(gu)障及處(chu)理方式 真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)在(zai)使(shi)用長時(shi)(shi)(shi)間后會(hui)(hui)出現一些故(gu)障,這(zhe)是(shi)在(zai)所(suo)難(nan)免的(de)(de)。今天八佳小編就和大家(jia)(jia)說說當(dang)故(gu)障出現,要做哪些處(chu)理方法。 1、故(gu)障現象(xiang):真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)運行正常(chang),但(dan)(dan)在(zai)正常(chang)過流(liu)保護動(dong)作(zuo)時(shi)(shi)(shi)燒(shao)(shao)毀較(jiao)(jiao)多(duo)的(de)(de)是(shi)KP晶(jing)閘(zha)管(guan)和快熔。 分析處(chu)理:過流(liu)保護時(shi)(shi)(shi)為(wei)了(le)向電(dian)(dian)(dian)網釋放(fang)平波電(dian)(dian)(dian)抗(kang)器的(de)(de)能(neng)量,整(zheng)流(liu)橋(qiao)由(you)整(zheng)流(liu)狀態轉到逆(ni)變(bian)(bian)狀態,這(zhe)時(shi)(shi)(shi)如果α>120度;,就有可能(neng)造成有源逆(ni)變(bian)(bian)顛(dian)覆,燒(shao)(shao)毀多(duo)只晶(jing)閘(zha)管(guan)和快熔,開關(guan)跳伴(ban)隨(sui)有巨大的(de)(de)電(dian)(dian)(dian)流(liu)短路爆(bao)炸聲,對(dui)變(bian)(bian)壓器產生較(jiao)(jiao)大的(de)(de)電(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)磁力沖擊(ji),嚴(yan)重時(shi)(shi)(shi)會(hui)(hui)損(sun)壞變(bian)(bian)亞(ya)器。 2、故(gu)障現象(xiang):真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)運行正常(chang),但(dan)(dan)在(zai)高電(dian)(dian)(dian)壓區內(nei)某點附近設備工作(zuo)不穩定,直流(liu)電(dian)(dian)(dian)壓表晃動(dong),設備伴(ban)隨(sui)有吱(zhi)(zhi)吱(zhi)(zhi)的(de)(de)聲音,這(zhe)種情況極(ji)容易造成逆(ni)變(bian)(bian)橋(qiao)顛(dian)覆燒(shao)(shao)毀晶(jing)閘(zha)管(guan)。 分析處(chu)理:這(zhe)種故(gu)障較(jiao)(jiao)難(nan)排除,多(duo)發生于設備的(de)(de)某部(bu)件高壓打(da)(da)(da)火(huo): (1)真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)的(de)(de)連接(jie)(jie)銅排接(jie)(jie)頭螺絲(si)松動(dong)造成打(da)(da)(da)火(huo) (2)斷路器主接(jie)(jie)頭氧化導致打(da)(da)(da)火(huo); (3)補(bu)償(chang)電(dian)(dian)(dian)容接(jie)(jie)線(xian)樁螺絲(si)松動(dong),引(yin)起(qi)打(da)(da)(da)火(huo),補(bu)償(chang)電(dian)(dian)(dian)容內(nei)部(bu)放(fang)電(dian)(dian)(dian)阻(zu)容吸收電(dian)(dian)(dian)打(da)(da)(da)火(huo); (4)水冷散熱(re)器絕緣部(bu)分太臟或炭(tan)化對(dui)地打(da)(da)(da)火(huo); (5)真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)爐(lu)(lu)體(ti)(ti)(ti)感應(ying)線(xian)圈對(dui)爐(lu)(lu)殼/爐(lu)(lu)底(di)板打(da)(da)(da)火(huo),爐(lu)(lu)體(ti)(ti)(ti)感應(ying)線(xian)圈匝(za)間距太近,匝(za)間打(da)(da)(da)火(huo)或起(qi)弧。固定爐(lu)(lu)體(ti)(ti)(ti)感應(ying)線(xian)圈的(de)(de)絕緣柱因高溫炭(tan)化放(fang)電(dian)(dian)(dian)打(da)(da)(da)火(huo) (6)晶(jing)閘(zha)管(guan)內(nei)部(bu)打(da)(da)(da)火(huo)。 以上就是(shi)真(zhen)(zhen)空(kong)(kong)熔煉(lian)(lian)(lian)爐(lu)(lu)廠家(jia)(jia)分析的(de)(de)兩種常(chang)見的(de)(de)故(gu)障。大家(jia)(jia)明白(bai)(bai)了(le)嗎(ma)?如果還有不明白(bai)(bai),也可以打(da)(da)(da)電(dian)(dian)(dian)話咨詢。
