可控矽作為中頻爐設備的重要係統組成部分，一旦出現故障，往往會導致係統效率下降或停止運行，嚴重的甚至會造成設備本身的損壞。那麼，中zhong頻pin爐lu可ke控kong矽gui在zai平ping時shi使shi用yong過guo程cheng中zhong都dou經jing常chang會hui出chu現xian哪na些xie問wen題ti
？出chu現xian這zhe些xie故gu障zhang的de原yuan因yin有you哪na些xie？今jin天tian小xiao編bian為wei大da家jia總zong結jie了le一yi些xie比bi較jiao常chang見jian的de可ke控kong矽gui損sun壞huai原yuan因yin和he診zhen斷duan經jing驗yan，在zai這zhe裏li與yu大da家jia一yi起qi分fen享xiang。

第二種經常遇到的中頻爐可控矽故障現象
，相信很多工程師都曾經遇到過，那就是槽路連接導線有you接jie觸chu不bu良liang和he斷duan線xian情qing況kuang。遇yu到dao這zhe種zhong問wen題ti時shi，工gong程cheng技ji術shu人ren員yuan需xu要yao全quan麵mian檢jian查zha槽cao路lu連lian接jie導dao線xian，根gen據ju實shi際ji情qing況kuang酌zhuo情qing處chu理li。當dang槽cao路lu連lian接jie導dao線xian有you接jie觸chu不bu良liang或huo斷duan線xian情qing況kuang時shi，功gong率lv升sheng到dao一yi定ding值zhi後hou會hui產chan生sheng打da火huo現xian象xiang
，影ying響xiang了le設she備bei的de正zheng常chang工gong作zuo，從cong而er導dao致zhi設she備bei保bao護hu動dong作zuo。有you時shi因yin打da火huo時shi會hui在zai可ke控kong矽gui兩liang端duan產chan生sheng瞬shun時shi過guo電dian壓ya，如ru果guo過guo壓ya保bao護hu動dong作zuo來lai不bu及ji，會hui燒shao壞huai可ke控kong矽gui元yuan件jian。該gai現xian象xiang經jing常chang會hui出chu現xian過guo電dian壓ya、過電流同時動作。

可ke控kong矽gui冷leng卻que係xi統tong故gu障zhang也ye同tong樣yang是shi在zai中zhong頻pin爐lu運yun行xing過guo程cheng中zhong，比bi較jiao多duo發fa的de故gu障zhang問wen題ti之zhi一yi。由you於yu可ke控kong矽gui在zai工gong作zuo時shi發fa熱re量liang很hen大da，需xu要yao對dui其qi冷leng卻que才cai能neng保bao證zheng正zheng常chang工gong作zuo，一yi般ban可ke控kong矽gui的de冷leng卻que有you兩liang種zhong方fang式shi：一種是水冷
，另一種是風冷。水冷的應用較為廣泛
，風冷一般隻用於100KW以(yi)下(xia)的(de)電(dian)源(yuan)設(she)備(bei)。通(tong)常(chang)采(cai)用(yong)水(shui)冷(leng)方(fang)式(shi)的(de)中(zhong)頻(pin)設(she)備(bei)均(jun)設(she)有(you)水(shui)壓(ya)保(bao)護(hu)電(dian)路(lu)

除chu了le上shang麵mian提ti及ji的de幾ji種zhong可ke控kong矽gui常chang見jian故gu障zhang之zhi外wai，電dian抗kang器qi故gu障zhang在zai一yi些xie比bi較jiao老lao的de中zhong頻pin爐lu設she備bei中zhong也ye比bi較jiao多duo發fa。由you於yu電dian抗kang器qi內nei部bu打da火huo造zao成cheng逆ni變bian側ce的de電dian流liu斷duan續xu，因yin此ci也ye會hui在zai逆ni變bian輸shu入ru側ce產chan生sheng高gao壓ya燒shao壞huai可ke控kong矽gui。另ling外wai，如ru果guo在zai維wei修xiu中zhong更geng換huan了le電dian抗kang器qi，而er電dian抗kang器qi的de電dian感gan量liang、鐵芯麵積小於要求值
，會使電抗器在大電流工作時，因飽和失去限流作用燒壞可控矽。
