  • 箱式高溫電阻爐的溫度提升不上去怎么回事???
        瀏覽:10478    日期:2011/08/11    
    問: ; ; ;我的電爐額定溫度是1400℃,功率達4KW,剛看了下有根硅碳棒斷了,把“硅碳棒”全換掉了。
       ; ; ;八根長450mm的電阻大約5歐姆,我按說明書接線方法分別用四根串聯然后并聯,但電源跳閘了之后試著將8根硅碳棒串聯好了。我的爐子可以開工了,但是溫度達到930℃左右就再也升不上去了,緊急求助啊。。。謝謝
    答:新硅碳棒阻值比老棒小功率大電流大才會跳閘
    用四根串聯,后并聯電源跳閘有可能,按理來說應該采取調壓器降壓,沒有調壓器,經過930℃左右燒結,然后四根串聯后并聯,這時功率應該回下來點了。在不可以的話就換個大一點的電器原件和電線保證可以搞定,八根硅碳棒串聯功率太小,肯定提高不了溫度。  如果您還有什么問題可以直接打電話來問,鄭州科晶電爐!
