此外(wai)，挑選(xuan)線圈(quan)(quan)(quan)(quan)時，還要考慮(lv)其(qi)(qi)線徑，材(cai)質，耐(nai)溫耐(nai)壓性能等(deng)(deng)。這些也(ye)(ye)都是(shi)(shi)由(you)其(qi)(qi)使用(yong)(yong)(yong)條件決定(ding)(ding)的(de)。在實(shi)際選(xuan)配(pei)過程中，先要根據加(jia)(jia)熱(re)(re)(re)需(xu)(xu)求(qiu)確(que)定(ding)(ding)所(suo)需(xu)(xu)設備(bei)(bei)功(gong)率，然(ran)后就可(ke)以(yi)(yi)知道其(qi)(qi)輸出電(dian)(dian)(dian)流值(zhi)，進而確(que)定(ding)(ding)線徑、材(cai)質，然(ran)后視現(xian)場的(de)溫度情況，散熱(re)(re)(re)情況等(deng)(deng)考慮(lv)其(qi)(qi)耐(nai)溫性能。如(ru)(ru)果挑選(xuan)線圈(quan)(quan)(quan)(quan)時沒有(you)考慮(lv)到(dao)這些因素，就很容易(yi)出現(xian)設備(bei)(bei)故障(zhang)，例如(ru)(ru)線圈(quan)(quan)(quan)(quan)被燒壞，加(jia)(jia)熱(re)(re)(re)效(xiao)率低下(xia)，線圈(quan)(quan)(quan)(quan)不(bu)耐(nai)用(yong)(yong)(yong)等(deng)(deng)問題。輕則影響生產(chan)，重則造成人(ren)身事(shi)故。二線圈(quan)(quan)(quan)(quan)繞制(zhi)(zhi)：表面(mian)看來，線圈(quan)(quan)(quan)(quan)繞制(zhi)(zhi)這工作似乎是(shi)(shi)沒技術含量(liang)的(de)，不(bu)就是(shi)(shi)把線材(cai)繞下(xia)組成個(ge)線圈(quan)(quan)(quan)(quan)嘛，這誰不(bu)會(hui)？但(dan)實(shi)際上并沒有(you)那(nei)么簡單，線圈(quan)(quan)(quan)(quan)的(de)繞制(zhi)(zhi)需(xu)(xu)要考慮(lv)到(dao)疊加(jia)(jia)、干擾、散熱(re)(re)(re)、距(ju)離、感(gan)(gan)量(liang)匹配(pei)等(deng)(deng)因素。不(bu)同(tong)功(gong)率的(de)電(dian)(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)器(qi)其(qi)(qi)所(suo)需(xu)(xu)要的(de)線圈(quan)(quan)(quan)(quan)電(dian)(dian)(dian)感(gan)(gan)量(liang)是(shi)(shi)不(bu)樣的(de)，只有(you)實(shi)際電(dian)(dian)(dian)感(gan)(gan)量(liang)和理論值(zhi)直(zhi)，才能保證電(dian)(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)器(qi)的(de)功(gong)率大化。例如(ru)(ru)，臺30KW的(de)電(dian)(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)器(qi)，其(qi)(qi)理論電(dian)(dian)(dian)感(gan)(gan)量(liang)是(shi)(shi)240μH，線圈(quan)(quan)(quan)(quan)繞制(zhi)(zhi)時，只有(you)實(shi)際感(gan)(gan)量(liang)為240μH，其(qi)(qi)功(gong)率才有(you)可(ke)能完全(quan)達到(dao)。如(ru)(ru)果實(shi)際感(gan)(gan)量(liang)是(shi)(shi)100μH、150μH、300μH、400μH，那(nei)其(qi)(qi)這臺設備(bei)(bei)的(de)實(shi)際使用(yong)(yong)(yong)功(gong)率可(ke)能就只有(you)20KW，15KW，甚(shen)至根本啟動不(bu)了。三適(shi)用(yong)(yong)(yong)見場：電(dian)(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)器(qi)的(de)廣泛應用(yong)(yong)(yong)性決定(ding)(ding)了其(qi)(qi)現(xian)場使用(yong)(yong)(yong)情況的(de)復(fu)雜。在電(dian)(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)器(qi)眾多的(de)使用(yong)(yong)(yong)域中，食品、塑料、化工、印(yin)刷、供(gong)暖、垃圾處理，每(mei)個(ge)行業的(de)應用(yong)(yong)(yong)場景(jing)都不(bu)同(tong)，就是(shi)(shi)同(tong)個(ge)行業中，每(mei)個(ge)客戶的(de)使用(yong)(yong)(yong)現(xian)場也(ye)(ye)有(you)很大的(de)差(cha)別。所(suo)以(yi)(yi)，電(dian)(dian)(dian)磁線圈(quan)(quan)(quan)(quan)不(bu)具有(you)普(pu)遍適(shi)用(yong)(yong)(yong)性，是(shi)(shi)種(zhong)不(bu)同(tong)使用(yong)(yong)(yong)場景(jing)有(you)不(bu)同(tong)繞法的(de)非標(biao)配(pei)件。

挑選好(hao)的(de)電磁(ci)加熱器有什技巧？

1、性能(neng)：隨著(zhu)科學技術(shu)的(de)(de)進步，電(dian)磁(ci)(ci)加(jia)熱(re)器的(de)(de)功(gong)(gong)能(neng)集(ji)成程度非常(chang)高，些產品甚(shen)至集(ji)中(zhong)了各(ge)行各(ge)業(ye)工(gong)廠加(jia)熱(re)設備等等諸多功(gong)(gong)能(neng)，那么，是不(bu)是功(gong)(gong)能(neng)越(yue)多就越(yue)好呢？這(zhe)不(bu)定，因(yin)為(wei)很多功(gong)(gong)能(neng)或許客(ke)戶在以后(hou)的(de)(de)日子(zi)中(zhong)根本用不(bu)上。般工(gong)廠在考慮(lv)和挑(tiao)選電(dian)磁(ci)(ci)加(jia)熱(re)器的(de)(de)功(gong)(gong)能(neng)的(de)(de)時候，定要(yao)根據自(zi)己(ji)的(de)(de)實際需要(yao)購買，注重自(zi)己(ji)需要(yao)多大(da)功(gong)(gong)率(lv)的(de)(de)電(dian)磁(ci)(ci)加(jia)熱(re)控制器來選擇控制器。

2、節(jie)能(neng)與(yu)環保：眼下階梯電(dian)價(jia)即(ji)將實施，選擇款(kuan)節(jie)能(neng)的(de)(de)(de)產品也十分(fen)必要，畢竟電(dian)用的(de)(de)(de)越多，單價(jia)也將升(sheng)高，而且，本身電(dian)磁加(jia)熱器也是高功(gong)率(lv)電(dian)器，因此選購的(de)(de)(de)時候更應該注(zhu)意其能(neng)耗。當前(qian)，市場上銷售的(de)(de)(de)電(dian)磁加(jia)熱控制器，很多新型產品都(dou)使(shi)用了(le)節(jie)能(neng)與(yu)環保的(de)(de)(de)技術(shu)與(yu)設計，這對于消費者來說是有利的(de)(de)(de)。

下電(dian)磁(ci)加熱(re)器耗(hao)電(dian)與什么有關：

1、電(dian)(dian)磁加(jia)(jia)熱(re)器在工(gong)作(zuo)中(zhong)會直加(jia)(jia)熱(re)到(dao)設置的(de)溫度(du)，當(dang)溫度(du)沒達到(dao)設置的(de)溫度(du)時，電(dian)(dian)磁加(jia)(jia)熱(re)器就(jiu)會直加(jia)(jia)熱(re)，當(dang)達到(dao)了預設的(de)溫度(du)以后電(dian)(dian)磁加(jia)(jia)熱(re)器就(jiu)停止加(jia)(jia)熱(re)了，也就(jiu)不再(zai)耗電(dian)(dian)了。

2、電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)每個小(xiao)時的(de)(de)耗(hao)電(dian)(dian)(dian)量多(duo)少與電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)加(jia)熱(re)(re)(re)(re)的(de)(de)時間長短有關。電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)剛工(gong)(gong)作是(shi)滿功率，加(jia)熱(re)(re)(re)(re)溫度到溫度以后(hou)會停止然后(hou)再加(jia)熱(re)(re)(re)(re)。總體(ti)上(shang)來說，電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)耗(hao)電(dian)(dian)(dian)量是(shi)很小(xiao)的(de)(de)，因(yin)為電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)不是(shi)直加(jia)熱(re)(re)(re)(re)工(gong)(gong)作的(de)(de)，而(er)是(shi)有間隙的(de)(de)加(jia)熱(re)(re)(re)(re)的(de)(de)，達到溫度后(hou)就(jiu)停止加(jia)熱(re)(re)(re)(re)，之后(hou)就(jiu)開始保溫工(gong)(gong)作，直到溫度沒達到預設的(de)(de)溫度后(hou)再加(jia)熱(re)(re)(re)(re)下，整體(ti)上(shang)來講，電(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)(re)器(qi)(qi)(qi)并(bing)不是(shi)直加(jia)熱(re)(re)(re)(re)耗(hao)電(dian)(dian)(dian)的(de)(de)，這也是(shi)它比較省電(dian)(dian)(dian)的(de)(de)個原因(yin)。

3、料筒上還包(bao)有(you)層保溫(wen)棉(mian)也(ye)能起到(dao)保溫(wen)和(he)隔熱(re)的效果，那(nei)么熱(re)量就(jiu)不會損失掉了(le)，那(nei)么能夠持(chi)續(xu)恒(heng)溫(wen)加熱(re)的時間就(jiu)越長了(le)。耗電量也(ye)就(jiu)越小了(le)。

電壓(ya)340--350，電流65--68，加熱作用太慢。有什么(me)好辦法(fa)提高電壓(ya)嗎(ma)？

1、160KW的(de)變壓器用了(le)125A的(de)電(dian)流(liu)，那么也就是只用了(le)近1半的(de)負載(zai)罷了(le)，這(zhe)(zhe)個(ge)情況電(dian)壓由(you)410V～415V降(jiang)到(dao)340V～350V這(zhe)(zhe)是不正(zheng)常的(de)，從數據上看您這(zhe)(zhe)邊的(de)供電(dian)網還(huan)是非常不錯的(de)，這(zhe)(zhe)里(li)要是線路(lu)太長(chang)，線損太大引起。

2、可以用電(dian)容補(bu)償(chang)(chang)嗎?工(gong)業上(shang)(shang)高(gao)壓電(dian)容補(bu)償(chang)(chang)，這要是(shi)針對(dui)變壓器(qi)功(gong)率(lv)因數太低（補(bu)償(chang)(chang)前(qian)只(zhi)有0.8左(zuo)右(you)），如果您的變壓器(qi)之前(qian)沒有做無功(gong)補(bu)償(chang)(chang)，那(nei)么(me)這還是(shi)有作(zuo)(zuo)用的，并且也定要補(bu)償(chang)(chang)，不然電(dian)力公司檢測出(chu)來會被罰款的，但(dan)如1剖析(xi)，您這邊要不是(shi)功(gong)率(lv)因數低造成，所(suo)以對(dui)于(yu)電(dian)壓的上(shang)(shang)升作(zuo)(zuo)用不大。

3、50kw電(dian)磁加(jia)熱器(qi)(qi)電(dian)流卻只(zhi)有65A～68A，依(yi)照這個(ge)參數(shu)核算這臺控制(zhi)器(qi)(qi)連50KW都(dou)達(da)不(bu)到，或(huo)許(xu)您被騙(pian)了(le)(le)，隨著電(dian)磁加(jia)熱器(qi)(qi)行業(ye)的(de)競(jing)爭(zheng)劇烈，有非(fei)常多不(bu)法的(de)商家經常用小功(gong)率產品(pin)假充大功(gong)率產品(pin)再以相(xiang)對較低的(de)價(jia)格(ge)進行販(fan)賣，如用40KW超(chao)載運用假充50KW甚至(zhi)60KW再以比(bi)商場正(zheng)常50KW或(huo)許(xu)60KW的(de)價(jia)了(le)(le)解到的(de)數(shu)據。

工業運(yun)用電(dian)磁加(jia)熱器的五大優勢(shi)：

1、工作環(huan)境(jing)舒適。由于電(dian)阻式加熱(re)時，在部分熱(re)量輻射到空氣(qi)中，導致(zhi)員工工作環(huan)境(jing)溫度升(sheng)高，有(you)些車間(jian)還安(an)裝(zhuang)空調(diao)來降(jiang)溫，這樣樣，就(jiu)增(zeng)加了費用，導致(zhi)車間(jian)運行成本過高。改用電(dian)磁加熱(re)器后(hou)，線圈不存在發熱(re)，因此(ci)，環(huan)境(jing)工作溫度不會升(sheng)高，更(geng)不需要(yao)安(an)裝(zhuang)空調(diao)降(jiang)溫，車間(jian)不再出現(xian)溫度悶(men)熱(re)。

2、節能(neng)省電(dian)，達(da)到(dao)大幅度節能(neng)源，而比(bi)過(guo)去的電(dian)阻(zu)式加熱(re)方(fang)式是靠自(zi)身發熱(re)，通過(guo)接觸(chu)傳導的方(fang)式再把(ba)熱(re)量傳到(dao)炮(pao)筒中，還有(you)部分的能(neng)源輻射到(dao)空氣中，所以電(dian)阻(zu)式加熱(re)的熱(re)效率僅(jin)50-60%。本公司(si)的電(dian)磁加熱(re)器在拉(la)絲機中改造(zao)時(shi)節能(neng)明(ming)顯，達(da)45%以上(shang)，在大功(gong)率塑料機械設(she)備比(bi)如造(zao)粒機中改造(zao)時(shi)，節能(neng)效果(guo)更顯著(zhu)，可達(da)50%以上(shang)。

3、加(jia)熱(re)速(su)度(du)(du)快，由于(yu)利用電(dian)磁磁感應生產渦流發熱(re)原理，線圈(quan)本(ben)身(shen)不發熱(re)，而是(shi)炮(pao)筒自(zi)身(shen)發熱(re)。溫度(du)(du)升快速(su)度(du)(du)加(jia)快。而電(dian)阻式是(shi)靠自(zi)身(shen)發熱(re)，再傳出給炮(pao)筒，故加(jia)熱(re)速(su)度(du)(du)理所當然慢(man)很多。

4、維護成本(ben)低，般壽命(ming)達5年以上。線圈的表面溫度(du)僅不到(dao)100度(du)。有時(shi)僅70度(du)以內，手可觸摸。而(er)般電阻(zu)式由(you)于自身發(fa)熱，壽命(ming)很(hen)短，經常(chang)要維護，故(gu)造成維護成本(ben)過高。

5、在塑(su)料管(guan)道加(jia)熱面積小時可(ke)獲(huo)得(de)較大(da)的功率(lv)(lv)，傳統的電阻式般大(da)為(wei)5KW，基本上限狀態(tai)，而電磁加(jia)熱器在小面積大(da)可(ke)獲(huo)得(de)30KW甚至(zhi)更(geng)高功率(lv)(lv)，以保證出料的數量(liang)和品質。

電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)的(de)(de)(de)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)情況是(shi)(shi)怎樣的(de)(de)(de)？工作(zuo)原(yuan)理(li)是(shi)(shi)把220V或者380V交流電(dian)(dian)(dian)(dian)(dian)，整流后轉換成(cheng)直(zhi)(zhi)流電(dian)(dian)(dian)(dian)(dian)，再將直(zhi)(zhi)流電(dian)(dian)(dian)(dian)(dian)進(jin)行濾波，利(li)用IGBT或者可控硅再將直(zhi)(zhi)流變(bian)成(cheng)交流，在感應線(xian)圈內產(chan)生高頻磁(ci)(ci)(ci)(ci)(ci)力線(xian)，是(shi)(shi)感應線(xian)圈內導體工件(jian)表面產(chan)生渦流依靠自(zi)生內阻發熱(re)(re)(re)(re)(re)(re)(re)(re)。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)工作(zuo)中當(dang)溫(wen)(wen)度(du)(du)(du)沒(mei)達(da)到(dao)設置的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)時(shi)(shi)(shi)(shi)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)就(jiu)(jiu)(jiu)會(hui)直(zhi)(zhi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)，當(dang)達(da)到(dao)了(le)預設的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)以后電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)就(jiu)(jiu)(jiu)停止加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)了(le)，也就(jiu)(jiu)(jiu)不(bu)(bu)再耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)了(le)。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)每個小時(shi)(shi)(shi)(shi)的(de)(de)(de)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)多(duo)少與(yu)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)時(shi)(shi)(shi)(shi)間長短有關。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)剛(gang)工作(zuo)是(shi)(shi)滿功(gong)率，加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)溫(wen)(wen)度(du)(du)(du)了(le)，就(jiu)(jiu)(jiu)是(shi)(shi)工作(zuo)會(hui)，停會(hui)。總體上來說，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)是(shi)(shi)很(hen)小的(de)(de)(de)，因為電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)不(bu)(bu)是(shi)(shi)直(zhi)(zhi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)工作(zuo)的(de)(de)(de)，而是(shi)(shi)有間隙(xi)的(de)(de)(de)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)，先是(shi)(shi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)，然后達(da)到(dao)溫(wen)(wen)度(du)(du)(du)后就(jiu)(jiu)(jiu)停止加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)，之后就(jiu)(jiu)(jiu)開始保溫(wen)(wen)工作(zuo)，直(zhi)(zhi)到(dao)溫(wen)(wen)度(du)(du)(du)沒(mei)達(da)到(dao)預設的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)后再加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)下，整體上來講，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)并(bing)不(bu)(bu)是(shi)(shi)直(zhi)(zhi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)，所以也是(shi)(shi)比較省(sheng)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)個原(yuan)因。同時(shi)(shi)(shi)(shi)因為料筒上還(huan)包有層(ceng)保溫(wen)(wen)棉，能起到(dao)保溫(wen)(wen)和隔熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)效果，那么熱(re)(re)(re)(re)(re)(re)(re)(re)量(liang)就(jiu)(jiu)(jiu)不(bu)(bu)會(hui)損失(shi)掉了(le)，那么能夠持續恒溫(wen)(wen)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)時(shi)(shi)(shi)(shi)間就(jiu)(jiu)(jiu)越長了(le)。耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)也就(jiu)(jiu)(jiu)越小了(le)。通(tong)過(guo)上述(shu)對電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)感應加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)改造時(shi)(shi)(shi)(shi)所配功(gong)率的(de)(de)(de)介紹，我(wo)們可以了(le)解電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)時(shi)(shi)(shi)(shi)間越短那么耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)就(jiu)(jiu)(jiu)越小，反之電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)(de)時(shi)(shi)(shi)(shi)間越長，耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)(dian)量(liang)就(jiu)(jiu)(jiu)越大。

電(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)器，是現今工業域和民用設備(bei)中廣泛的(de)(de)(de)(de)種(zhong)加(jia)熱(re)(re)方式，采用電(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)技(ji)術，電(dian)(dian)(dian)磁(ci)(ci)感(gan)(gan)應加(jia)熱(re)(re)技(ji)術簡稱為(wei) IH(Induction Heating)技(ji)術，是在(zai)法拉(la)第感(gan)(gan)應定律(lv)的(de)(de)(de)(de)基礎(chu)上發(fa)展(zhan)起來(lai)的(de)(de)(de)(de)，是法拉(la)第感(gan)(gan)應定律(lv)的(de)(de)(de)(de)種(zhong)應用形式。其本質就是利用電(dian)(dian)(dian)磁(ci)(ci)感(gan)(gan)應在(zai)柱體內產生渦流(liu)來(lai)給加(jia)熱(re)(re)工件(jian)的(de)(de)(de)(de)電(dian)(dian)(dian)加(jia)熱(re)(re)，它(ta)是把電(dian)(dian)(dian)能轉(zhuan)(zhuan)換(huan)(huan)為(wei)電(dian)(dian)(dian)磁(ci)(ci)能，再由電(dian)(dian)(dian)磁(ci)(ci)能轉(zhuan)(zhuan)換(huan)(huan)為(wei)電(dian)(dian)(dian)能，電(dian)(dian)(dian)能在(zai)金屬(shu)內部轉(zhuan)(zhuan)變為(wei)熱(re)(re)能，達(da)到加(jia)熱(re)(re)金屬(shu)的(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)，從而杜了明火(huo)在(zai)加(jia)熱(re)(re)過程中的(de)(de)(de)(de)危害和干擾(rao)，是種(zhong)環保，提倡的(de)(de)(de)(de)加(jia)熱(re)(re)方案。

電磁加(jia)熱器線(xian)(xian)圈選型原則(ze)：線(xian)(xian)材本(ben)身：線(xian)(xian)材本(ben)身有很(hen)多種類(lei)，例(li)如高頻(pin)線(xian)(xian)、云母線(xian)(xian)、防水線(xian)(xian)、硅膠線(xian)(xian)、鍍鎳(nie)線(xian)(xian)、純鎳(nie)線(xian)(xian)、銅(tong)管、合金導線(xian)(xian)等，不同(tong)種類(lei)的(de)線(xian)(xian)材適用場合不同(tong)，選購前應仔細問詢(xun)。
