格蘭仕電磁爐不加熱怎么回事
一、電磁爐不加熱之內部因素條件保護
電(dian)磁爐(lu)不(bu)加(jia)熱1、IGBT過(guo)流(liu)保(bao)護(hu)(hu):過(guo)流(liu)保(bao)護(hu)(hu)強(qiang)制減小輸出功率或直接(jie)暫停工(gong)(gong)作,延時一段時間(jian)后再次(ci)啟動(dong)進入工(gong)(gong)作狀態。此類保(bao)護(hu)(hu)動(dong)作時會出現“有規律地間(jian)斷加(jia)熱”現象。
電磁(ci)爐不(bu)加熱2、溫度傳感(gan)器開路、短路保(bao)護:這類保(bao)護會強(qiang)制關閉工(gong)作中的電磁(ci)爐,并使電磁(ci)爐在沒有排除故障前(qian)都處于關閉狀態,任何鍵(jian)不(bu)起作用,并顯示電磁(ci)爐故障代碼。
電(dian)(dian)磁(ci)爐不(bu)加熱3、IGBT管(guan)超壓保護(hu)(hu):當某種(zhong)原因導致IGBT集(ji)(ji)電(dian)(dian)極電(dian)(dian)壓升(sheng)高(gao)并達(da)到保護(hu)(hu)觸發條件時,超壓保護(hu)(hu)動作,迫使電(dian)(dian)磁(ci)爐降低輸出(chu)(chu)功率,IGBT集(ji)(ji)電(dian)(dian)極電(dian)(dian)壓隨即(ji)降低。這一種(zhong)類的(de)保護(hu)(hu)電(dian)(dian)路動作有時會出(chu)(chu)現間斷加熱和輸出(chu)(chu)功率降低等現象。
二、電磁爐不加熱外部自然因素條件保護
電磁爐不(bu)加熱1、浪(lang)(lang)涌(yong)(yong)保(bao)護(hu)(hu):浪(lang)(lang)涌(yong)(yong)是電網中電壓在瞬時(shi)(shi)(shi)升高或降低時(shi)(shi)(shi)產生的一(yi)種(zhong)危害比較大(da)(da)的尖峰脈(mo)沖,過大(da)(da)的浪(lang)(lang)涌(yong)(yong)一(yi)般都會被壓敏電阻(zu)泄放掉,只有(you)一(yi)些(xie)較小(xiao)的浪(lang)(lang)涌(yong)(yong)會觸(chu)發(fa)浪(lang)(lang)涌(yong)(yong)保(bao)護(hu)(hu)電路動作。保(bao)護(hu)(hu)性(xing)質為(wei)短時(shi)(shi)(shi)暫(zan)(zan)停(ting)。如果電網陳舊,并且(qie)有(you)接觸(chu)不(bu)良的情況(kuang)時(shi)(shi)(shi),可能會出現不(bu)定時(shi)(shi)(shi)的暫(zan)(zan)停(ting)現象。
電(dian)(dian)(dian)(dian)磁(ci)爐不加熱2、電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓保(bao)護(hu)(hu):電(dian)(dian)(dian)(dian)壓高或電(dian)(dian)(dian)(dian)壓低(di)于電(dian)(dian)(dian)(dian)磁(ci)爐的工作電(dian)(dian)(dian)(dian)壓范圍時,出現保(bao)護(hu)(hu)。保(bao)護(hu)(hu)性質是強(qiang)制待機。并顯示故(gu)障代碼。
電磁爐不加熱(re)3、電磁爐內部過熱(re)保護(hu)(hu):保護(hu)(hu)觸(chu)發溫(wen)度(du)多在90到95度(du),解除(chu)溫(wen)度(du)在60到70度(du)。保護(hu)(hu)性質為暫停(ting)性停(ting)機,并顯示故障代碼。如果監(jian)測(ce)到溫(wen)度(du)達(da)到110度(du)時,保護(hu)(hu)電路強制(zhi)關機。
電磁爐不加熱4、鍋具超溫保護:這一種超溫保護又被稱為“防干燒保護”,觸發溫度為280到300度,也就是說一道280度,就會自動強制關機,解除溫度為70到80度,這種情況只要等到70度,就可以重新啟動使用了。格蘭仕電磁爐推薦>>
