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

電磁爐不加(jia)(jia)熱(re)1、IGBT過流保護(hu)(hu)：過流保護(hu)(hu)強制(zhi)減小輸出功率或直接暫(zan)停(ting)工(gong)作，延時(shi)一段時(shi)間(jian)后(hou)再次啟動進入(ru)工(gong)作狀態。此類(lei)保護(hu)(hu)動作時(shi)會(hui)出現“有規律地(di)間(jian)斷加(jia)(jia)熱(re)”現象。

二、電磁爐不加熱外部自然因素條件保護

電(dian)(dian)磁(ci)爐不加(jia)熱1、浪(lang)(lang)涌(yong)(yong)(yong)保(bao)護(hu)(hu)：浪(lang)(lang)涌(yong)(yong)(yong)是電(dian)(dian)網(wang)中電(dian)(dian)壓在瞬時(shi)(shi)(shi)升高或降(jiang)低時(shi)(shi)(shi)產生(sheng)的(de)一(yi)種危害比(bi)較(jiao)大的(de)尖峰脈沖，過大的(de)浪(lang)(lang)涌(yong)(yong)(yong)一(yi)般都會被壓敏電(dian)(dian)阻泄放掉(diao)，只有一(yi)些較(jiao)小的(de)浪(lang)(lang)涌(yong)(yong)(yong)會觸(chu)發浪(lang)(lang)涌(yong)(yong)(yong)保(bao)護(hu)(hu)電(dian)(dian)路動(dong)作(zuo)。保(bao)護(hu)(hu)性質為(wei)短時(shi)(shi)(shi)暫停(ting)。如果電(dian)(dian)網(wang)陳(chen)舊，并且有接觸(chu)不良的(de)情況(kuang)時(shi)(shi)(shi)，可(ke)能會出(chu)現不定時(shi)(shi)(shi)的(de)暫停(ting)現象。

電(dian)(dian)磁(ci)(ci)爐(lu)不加熱2、電(dian)(dian)網電(dian)(dian)壓(ya)(ya)(ya)保(bao)護：電(dian)(dian)壓(ya)(ya)(ya)高(gao)或電(dian)(dian)壓(ya)(ya)(ya)低于(yu)電(dian)(dian)磁(ci)(ci)爐(lu)的工(gong)作(zuo)電(dian)(dian)壓(ya)(ya)(ya)范圍時(shi)，出現保(bao)護。保(bao)護性質是強制待(dai)機。并顯示故障代碼。

電(dian)磁爐不(bu)加(jia)熱3、電(dian)磁爐內部(bu)過熱保(bao)護：保(bao)護觸發(fa)溫度(du)(du)多在90到(dao)95度(du)(du)，解(jie)除(chu)溫度(du)(du)在60到(dao)70度(du)(du)。保(bao)護性質為暫(zan)停性停機，并顯(xian)示故(gu)障代碼。如果監測到(dao)溫度(du)(du)達到(dao)110度(du)(du)時(shi)，保(bao)護電(dian)路強制關機。

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>>
