中(zhong)(zhong)頻(pin)(pin)爐(lu)使(shi)用電源(yuan)方(fang)式不同(tong)于工頻(pin)(pin)電爐(lu)中(zhong)(zhong)頻(pin)(pin)電源(yuan),將單相交流中(zhong)(zhong)頻(pin)(pin)電壓、中(zhong)(zhong)頻(pin)(pin)電源(yuan),電流輸(shu)入加(jia)熱器(qi)產生感應電對電爐(lu)內的(de)水(shui)進行(xing)感應加(jia)熱。因此本(ben)(ben)鍋爐(lu)的(de)加(jia)熱過程中(zhong)(zhong)水(shui)電分離，安全可靠的(de)。本(ben)(ben)鍋爐(lu)還裝(zhuang)有以(yi)下保護裝(zhuang)置：

　　1、水控和傳感溫調(diao)報(bao)警均可轉(zhuan)入自動(dong)保(bao)護(hu)(hu)系統，故(gu)障時，中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源相(xiang)(xiang)應(ying)指示燈(deng)閃亮，且自動(dong)停(ting)機。，是將380V的工頻(pin)交流(liu)(liu)電(dian)(dian)源輸入中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源柜（中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源柜內具有過壓(ya)(ya)保(bao)護(hu)(hu)、中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源,過流(liu)(liu)保(bao)護(hu)(hu)、如有過壓(ya)(ya)、過流(liu)(liu)現象會自動(dong)停(ting)機報(bao)警），中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源,在中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)源柜內將工頻(pin)交流(liu)(liu)電(dian)(dian)源整流(liu)(liu)為單(dan)相(xiang)(xiang)直(zhi)流(liu)(liu)電(dian)(dian)，再(zai)通過逆變成(cheng)為單(dan)相(xiang)(xiang)交流(liu)(liu)中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)壓(ya)(ya)、電(dian)(dian)流(liu)(liu)（單(dan)相(xiang)(xiang)交流(liu)(liu)中(zhong)(zhong)(zhong)頻(pin)電(dian)(dian)壓(ya)(ya)、電(dian)(dian)流(liu)(liu)是安(an)全的）。

　　2、裝有液晶數字顯(xian)(xian)示(shi)，能準確直觀地顯(xian)(xian)示(shi)供水(shui)(shui)(shui)溫度，回水(shui)(shui)(shui)溫度；爐內水(shui)(shui)(shui)位高低，可(ke)在水(shui)(shui)(shui)位計上顯(xian)(xian)示(shi)，操作人員(yuan)可(ke)以很(hen)清楚(chu)地掌握鍋爐運行情況。

　　3、裝有(you)溫(wen)(wen)控(kong)儀，水控(kong)儀，可以自動(dong)溫(wen)(wen)調，中頻(pin)電(dian)源(yuan)自動(dong)補水，可根據用(yong)戶需要設(she)定供水溫(wen)(wen)度，回水溫(wen)(wen)度自動(dong)調節。供水溫(wen)(wen)度超(chao)過設(she)定溫(wen)(wen)度時，自動(dong)停機，中頻(pin)電(dian)源(yuan),回水溫(wen)(wen)度低于設(she)定溫(wen)(wen)度時，自動(dong)開(kai)機。
