不銹鋼電加熱管

    電(dian)(dian)熱管發熱量(liang)的計算(suan) 可以用調(diao)壓器通(tong)過改變(bian)輸入電(dian)(dian)壓和電(dian)(dian)流來改變(bian)發熱量(liang)。

    發熱(re)量(liang)與電(dian)壓(ya)平方成(cheng)(cheng)正比，與電(dian)流平方成(cheng)(cheng)正比。

    電(dian)壓變(bian)為(wei)(wei)原來(lai)的1/2時(shi)，發(fa)熱量變(bian)為(wei)(wei)1/4

    電(dian)流變為(wei)原來的1/2時，發熱量也變為(wei)1/4
