真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)常(chang)見的(de)(de)故(gu)障(zhang)(zhang)有(you)哪(na)些
真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)在(zai)使用長時(shi)(shi)間(jian)后(hou)會(hui)出現(xian)一些故(gu)障(zhang)(zhang),這是在(zai)所難(nan)免的(de)(de)。今天八佳小編就和(he)大家(jia)說說當故(gu)障(zhang)(zhang)出現(xian),要做哪(na)些處(chu)(chu)理方法(fa)。
1、故(gu)障(zhang)(zhang)現(xian)象: 真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)運(yun)行正常(chang),但在(zai)正常(chang)過流(liu)(liu)保護(hu)動(dong)作(zuo)時(shi)(shi)燒毀較(jiao)多的(de)(de)是KP晶閘管(guan)和(he)快(kuai)熔(rong)(rong)(rong)。
分(fen)(fen)(fen)析處(chu)(chu)理: 過流(liu)(liu)保護(hu)時(shi)(shi)為(wei)了(le)向(xiang)電(dian)(dian)(dian)(dian)(dian)網釋放平(ping)波電(dian)(dian)(dian)(dian)(dian)抗器(qi)的(de)(de)能量,整(zheng)流(liu)(liu)橋由整(zheng)流(liu)(liu)狀態轉(zhuan)到逆變(bian)狀態,這時(shi)(shi)如果α>120度;,就有(you)可能造(zao)成(cheng)有(you)源逆變(bian)顛覆,燒毀多只晶閘管(guan)和(he)快(kuai)熔(rong)(rong)(rong),開(kai)關跳伴隨有(you)巨大的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)短路爆炸聲,對(dui)變(bian)壓(ya)器(qi)產生較(jiao)大的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)和(he)電(dian)(dian)(dian)(dian)(dian)磁(ci)力(li)沖擊(ji),嚴重時(shi)(shi)會(hui)損壞變(bian)亞器(qi)。
2、故(gu)障(zhang)(zhang)現(xian)象: 真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)運(yun)行正常(chang),但在(zai)高電(dian)(dian)(dian)(dian)(dian)壓(ya)區內(nei)某點(dian)附近(jin)設(she)備(bei)工(gong)作(zuo)不(bu)(bu)穩(wen)定(ding),直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya)表晃動(dong),設(she)備(bei)伴隨有(you)吱吱的(de)(de)聲音,這種(zhong)情況極容(rong)易(yi)造(zao)成(cheng)逆變(bian)橋顛覆燒毀晶閘管(guan)。
分(fen)(fen)(fen)析處(chu)(chu)理: 這種(zhong)故(gu)障(zhang)(zhang)較(jiao)難(nan)排(pai)除,多發生于設(she)備(bei)的(de)(de)某部(bu)件高壓(ya)打(da)(da)(da)火(huo)
(1)真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)的(de)(de)連(lian)接(jie)銅排(pai)接(jie)頭(tou)螺(luo)絲松動(dong)造(zao)成(cheng)打(da)(da)(da)火(huo)
(2)斷路器(qi)主接(jie)頭(tou)氧化導致打(da)(da)(da)火(huo)
(3)補償電(dian)(dian)(dian)(dian)(dian)容(rong)接(jie)線(xian)樁螺(luo)絲松動(dong),引起打(da)(da)(da)火(huo),補償電(dian)(dian)(dian)(dian)(dian)容(rong)內(nei)部(bu)放電(dian)(dian)(dian)(dian)(dian)阻容(rong)吸收電(dian)(dian)(dian)(dian)(dian)打(da)(da)(da)火(huo)
(4)水(shui)冷散熱器(qi)絕(jue)緣部(bu)分(fen)(fen)(fen)太臟或炭化對(dui)地打(da)(da)(da)火(huo)
(5)真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)爐(lu)(lu)體(ti)(ti)感應(ying)線(xian)圈(quan)對(dui)爐(lu)(lu)殼(ke)/爐(lu)(lu) 底(di)板打(da)(da)(da)火(huo),爐(lu)(lu)體(ti)(ti)感應(ying)線(xian)圈(quan)匝間(jian)距(ju)太近(jin),匝間(jian)打(da)(da)(da)火(huo)或起弧。固定(ding)爐(lu)(lu)體(ti)(ti)感應(ying)線(xian)圈(quan)的(de)(de)絕(jue)緣柱因(yin)高溫炭化放電(dian)(dian)(dian)(dian)(dian)打(da)(da)(da)火(huo)
(6)晶閘管(guan)內(nei)部(bu)打(da)(da)(da)火(huo)。
以上(shang)就是真(zhen)(zhen)空(kong)(kong)(kong)(kong)熔(rong)(rong)(rong)煉爐(lu)(lu)廠(chang)家(jia)分(fen)(fen)(fen)析的(de)(de)兩種(zhong)常(chang)見的(de)(de)故(gu)障(zhang)(zhang)。大家(jia)明白了(le)嗎?如果還有(you)不(bu)(bu)明白,也可以打(da)(da)(da)電(dian)(dian)(dian)(dian)(dian)話咨(zi)詢。
