電磁(ci)加熱器用薄膜電容的要求和注意事項：

1、耐壓(ya)(ya)(ya)選(xuan)擇不當：例(li)如,交流(liu)輸(shu)入(ru)端,380V的(de)(de)線電(dian)(dian)壓(ya)(ya)(ya),EMI電(dian)(dian)路用的(de)(de)電(dian)(dian)容(rong)器,三(san)角形接法,部分工程師(shi)選(xuan)擇MKP-X2 275V.AC (這會導致電(dian)(dian)容(rong)擊穿(chuan))。例(li)如,LC諧(xie)振回路,很(hen)多工程師(shi)以(yi)為半(ban)橋(qiao)諧(xie)振電(dian)(dian)容(rong),耐壓(ya)(ya)(ya)只(zhi)是直流(liu)母(mu)線537V的(de)(de)半(ban)即可(實際上這是嚴重錯誤的(de)(de))。國(guo)內的(de)(de)機(ji)芯(xin),有使(shi)用的(de)(de)薄膜電(dian)(dian)容(rong)器耐壓(ya)(ya)(ya)等(deng)1200V 1600V 2000V 2500V 3000V 4000V 需要根(gen)據(ju)自己(ji)的(de)(de)實際電(dian)(dian)路來選(xuan)擇。正確(que)的(de)(de)方式是用示波(bo)器加高壓(ya)(ya)(ya)探頭,實際測量下機(ji)芯(xin)在大(da)功率的(de)(de)時候(hou),諧(xie)振電(dian)(dian)壓(ya)(ya)(ya)的(de)(de)波(bo)形。

2、電(dian)(dian)流(liu)(liu)(liu)選擇不當：很多企業的(de)(de)(de)(de)工程師,研發人員(yuan),對于直流(liu)(liu)(liu)母線支撐電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi),LC諧振電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi),電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)方(fang)面根本就(jiu)(jiu)沒(mei)經過具體計算和實(shi)際測(ce)(ce)量(liang)(liang),造成電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)工作溫度非(fei)常(chang)(chang)高,大大縮短(duan)薄膜電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)的(de)(de)(de)(de)使(shi)用(yong)壽命,嚴(yan)重的(de)(de)(de)(de)出現(xian)短(duan)時間就(jiu)(jiu)炸(zha)掉電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)了。正(zheng)(zheng)確(que)的(de)(de)(de)(de)方(fang)式,就(jiu)(jiu)是(shi)用(yong)電(dian)(dian)流(liu)(liu)(liu)互感器(qi)(qi)測(ce)(ce)量(liang)(liang)下諧振回(hui)路(lu)的(de)(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)值,還有通過機子在老化的(de)(de)(de)(de)時候測(ce)(ce)測(ce)(ce)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)的(de)(de)(de)(de)溫升是(shi)否正(zheng)(zheng)常(chang)(chang)。

3、接線(xian)方(fang)式不(bu)當：在設計(ji)電磁(ci)加熱機(ji)芯的(de)時候,很多(duo)情況下(xia)需要多(duo)個(ge)薄膜電容(rong)器并(bing)聯使用.并(bing)聯的(de)好處就是(shi)可以增加過流能力,降低溫升.但是(shi)并(bing)聯電路(lu),大(da)的(de)問題是(shi)過流不(bu)均.由于接線(xian)方(fang)式的(de)不(bu)當,往(wang)往(wang)造成并(bing)聯的(de)幾只(zhi)電容(rong)器,某(mou)個(ge)位置的(de)電容(rong)器溫度(du)高,容(rong)易先壞(huai)掉(diao)。

電磁(ci)加熱(re)控制器怎么安裝？

1、改造前先取下原設(she)備(bei)上(shang)面的電(dian)熱圈。

2、清潔料(liao)筒(tong)并測(ce)(ce)量料(liao)筒(tong)各種參數。將料(liao)筒(tong)清潔干(gan)凈并用(yong)(yong)工具測(ce)(ce)量料(liao)筒(tong)各種尺寸（管(guan)徑、長度(du)、加熱(re)區數、每(mei)區加熱(re)長度(du)、原功率大小(xiao)，以便(bian)確定用(yong)(yong)哪(na)種控制板）。

3、在料(liao)筒上包層隔熱保溫材(cai)(cai)料(liao)，按照步驟2將料(liao)筒清潔干凈后，在料(liao)筒上包上層隔熱保溫材(cai)(cai)料(liao)（石棉(mian)或者玻(bo)璃纖維均可），可以先做(zuo)區(qu)，區(qu)做(zuo)好后，再做(zuo)其它區(qu)，熟練且經驗豐富者可幾個(ge)加熱區(qu)起做(zuo) 。

4、用(yong)高溫(wen)布(bu)將保溫(wen)材(cai)料(liao)包好，保溫(wen)材(cai)料(liao)的(de)厚度根據使用(yong)的(de)不同的(de)電磁(ci)加熱(re)(re)控制器的(de)要求來(lai)配，保溫(wen)材(cai)料(liao)包好后，再(zai)用(yong)高溫(wen)布(bu)（纖(xian)維布(bu)）或者電木板(ban)（環(huan)氧樹脂(zhi)板(ban)）將保溫(wen)材(cai)料(liao)包緊(jin)起(qi)來(lai)，該步驟主要是確保料(liao)筒各處的(de)保溫(wen)材(cai)料(liao)厚度致，以保證電磁(ci)加熱(re)(re)的(de)磁(ci)場均(jun)。

5、纏繞(rao)高溫(wen)(wen)電纜，高溫(wen)(wen)電纜的規(gui)格與長(chang)度請根據(ju)各種不同(tong)型號電磁加(jia)熱控制器的要求選配，該步(bu)驟非常關鍵。

6、將(jiang)線(xian)(xian)圈與(yu)電磁(ci)加(jia)熱(re)控(kong)制(zhi)(zhi)器(qi)連接(jie)(jie)。則將(jiang)繞(rao)好(hao)的(de)(de)線(xian)(xian)圈與(yu)電磁(ci)加(jia)熱(re)控(kong)制(zhi)(zhi)器(qi)連接(jie)(jie)好(hao)，并給電磁(ci)加(jia)熱(re)控(kong)制(zhi)(zhi)器(qi)接(jie)(jie)上電源，即(ji)(ji)可對設備進行(xing)調(diao)試，需注(zhu)意的(de)(de)是調(diao)試過程中(zhong)要特別注(zhu)意測量電磁(ci)加(jia)熱(re)控(kong)制(zhi)(zhi)器(qi)的(de)(de)輸入電流與(yu)頻率。為保(bao)證設備的(de)(de)使用壽命建議電流調(diao)到額定工作電流的(de)(de)80%左(zuo)(zuo)右，如我司2.5KW的(de)(de)電磁(ci)加(jia)熱(re)控(kong)制(zhi)(zhi)板，額定工作電流是12A，則建議調(diao)到10A左(zuo)(zuo)右即(ji)(ji)可，或電流偏小則可減少(shao)線(xian)(xian)圈，反之則需再增加(jia)些線(xian)(xian)圈。

電磁加熱控制器(qi)運(yun)用在(zai)反應(ying)釜上有什么優(you)勢呢？

、加熱(re)升(sheng)溫時間短、能(neng)量轉換效率(lv)高，該設備采用(yong)就地電磁加熱(re)，直接加熱(re)罐體(ti)，減少中(zhong)間熱(re)傳遞(di)過程提高熱(re)效率(lv)利用(yong)。

二、安裝方便，次性投(tou)入成本低，只在(zai)原反應釜加入電磁感應器即可，不對(dui)原反應釜進行大量的改(gai)造(zao)。

三(san)、運行成本低，無需管道、鍋爐、煤場、智能監控，真正實現無人值守。

四、軟啟(qi)動(dong)：無啟(qi)動(dong)沖(chong)擊電(dian)流，可以(yi)有效保(bao)護設備不受傷害。

五(wu)、安(an)全防爆、無明火。線(xian)圈溫度在100度以內，加熱(re)部分采用電纜(lan)(lan)室結構，加熱(re)電纜(lan)(lan)本身不會(hui)產生熱(re)量。

六、升溫(wen)速(su)度(du)(du)快，溫(wen)度(du)(du)高(gao)，高(gao)可達600度(du)(du)加熱時(shi)，加熱介質與電分離，感應器本身不產生高(gao)溫(wen)，不產生火花，電源(yuan)采用特殊的(de)防爆外殼(ke)。

七、綠色環(huan)保，無(wu)任何廢棄物產生，符合可持續發展戰略。

電磁感應加熱(re)器不加熱(re)原因主要(yao)有以下三(san)點：

1、線路(lu)故障，沒電供及。

2、元(yuan)件損壞，查找(zhao)更換。

3、調(diao)整(zheng)不當，重(zhong)新調(diao)整(zheng)適(shi)當數(shu)據。

電(dian)磁加(jia)熱(re)器(qi)普通加(jia)熱(re)圈加(jia)熱(re)方式優(you)勢：

1、接(jie)觸式熱傳遞(di)加(jia)熱。

2、耗電的 30-70% 轉化為工作熱能。

3、加熱(re)通過接(jie)觸(chu)方式傳遞(di)熱(re)能。

4、加熱及(ji)冷卻都(dou)有慣(guan)性現象產(chan)生(sheng)，及(ji)升溫降溫都(dou)緩慢。

5、加熱有死角，不能完全包裹(guo)在料筒外層。

6、加熱圈損耗大，壽(shou)命短(duan)。

此外，挑選線(xian)(xian)圈(quan)(quan)(quan)時，還(huan)要(yao)(yao)(yao)考(kao)(kao)慮其(qi)(qi)線(xian)(xian)徑，材(cai)質(zhi)，耐(nai)溫(wen)(wen)耐(nai)壓性能等。這些也都是(shi)(shi)(shi)由其(qi)(qi)使(shi)(shi)用條件決(jue)定(ding)的(de)(de)(de)(de)。在(zai)(zai)實(shi)(shi)際選配(pei)過程中，先要(yao)(yao)(yao)根據加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)需求確(que)定(ding)所需設(she)備功(gong)率，然后就可(ke)以知(zhi)道其(qi)(qi)輸出電(dian)(dian)(dian)流值(zhi)(zhi)，進(jin)而確(que)定(ding)線(xian)(xian)徑、材(cai)質(zhi)，然后視現(xian)(xian)場(chang)(chang)的(de)(de)(de)(de)溫(wen)(wen)度情況(kuang)，散熱(re)(re)(re)(re)(re)情況(kuang)等考(kao)(kao)慮其(qi)(qi)耐(nai)溫(wen)(wen)性能。如(ru)(ru)果挑選線(xian)(xian)圈(quan)(quan)(quan)時沒有(you)(you)(you)考(kao)(kao)慮到這些因素(su)，就很(hen)(hen)容易出現(xian)(xian)設(she)備故(gu)障，例(li)如(ru)(ru)線(xian)(xian)圈(quan)(quan)(quan)被(bei)燒(shao)壞(huai)，加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)效率低(di)下(xia)，線(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)耐(nai)用等問題。輕(qing)則影響(xiang)生產，重則造成人(ren)身事故(gu)。二線(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)制(zhi)(zhi)：表面看來，線(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)制(zhi)(zhi)這工作似乎(hu)是(shi)(shi)(shi)沒技術含(han)量的(de)(de)(de)(de)，不(bu)(bu)(bu)就是(shi)(shi)(shi)把線(xian)(xian)材(cai)繞(rao)(rao)下(xia)組成個(ge)(ge)(ge)線(xian)(xian)圈(quan)(quan)(quan)嘛，這誰不(bu)(bu)(bu)會？但實(shi)(shi)際上(shang)并沒有(you)(you)(you)那(nei)么簡單，線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)繞(rao)(rao)制(zhi)(zhi)需要(yao)(yao)(yao)考(kao)(kao)慮到疊(die)加(jia)(jia)(jia)、干擾(rao)、散熱(re)(re)(re)(re)(re)、距離、感量匹(pi)配(pei)等因素(su)。不(bu)(bu)(bu)同(tong)功(gong)率的(de)(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器其(qi)(qi)所需要(yao)(yao)(yao)的(de)(de)(de)(de)線(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)感量是(shi)(shi)(shi)不(bu)(bu)(bu)樣(yang)的(de)(de)(de)(de)，只(zhi)有(you)(you)(you)實(shi)(shi)際電(dian)(dian)(dian)感量和理(li)論(lun)值(zhi)(zhi)直，才能保證(zheng)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器的(de)(de)(de)(de)功(gong)率大(da)化。例(li)如(ru)(ru)，臺(tai)30KW的(de)(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器，其(qi)(qi)理(li)論(lun)電(dian)(dian)(dian)感量是(shi)(shi)(shi)240μH，線(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)制(zhi)(zhi)時，只(zhi)有(you)(you)(you)實(shi)(shi)際感量為240μH，其(qi)(qi)功(gong)率才有(you)(you)(you)可(ke)能完全達到。如(ru)(ru)果實(shi)(shi)際感量是(shi)(shi)(shi)100μH、150μH、300μH、400μH，那(nei)其(qi)(qi)這臺(tai)設(she)備的(de)(de)(de)(de)實(shi)(shi)際使(shi)(shi)用功(gong)率可(ke)能就只(zhi)有(you)(you)(you)20KW，15KW，甚至(zhi)根本啟動(dong)不(bu)(bu)(bu)了。三適用見場(chang)(chang)：電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器的(de)(de)(de)(de)廣泛應(ying)用性決(jue)定(ding)了其(qi)(qi)現(xian)(xian)場(chang)(chang)使(shi)(shi)用情況(kuang)的(de)(de)(de)(de)復雜(za)。在(zai)(zai)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器眾(zhong)多的(de)(de)(de)(de)使(shi)(shi)用域(yu)中，食品、塑(su)料、化工、印刷、供暖(nuan)、垃圾處理(li)，每個(ge)(ge)(ge)行業的(de)(de)(de)(de)應(ying)用場(chang)(chang)景都不(bu)(bu)(bu)同(tong)，就是(shi)(shi)(shi)同(tong)個(ge)(ge)(ge)行業中，每個(ge)(ge)(ge)客(ke)戶的(de)(de)(de)(de)使(shi)(shi)用現(xian)(xian)場(chang)(chang)也有(you)(you)(you)很(hen)(hen)大(da)的(de)(de)(de)(de)差別(bie)。所以，電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)具有(you)(you)(you)普遍適用性，是(shi)(shi)(shi)種不(bu)(bu)(bu)同(tong)使(shi)(shi)用場(chang)(chang)景有(you)(you)(you)不(bu)(bu)(bu)同(tong)繞(rao)(rao)法的(de)(de)(de)(de)非(fei)標配(pei)件。

電磁加熱技術原(yuan)理：

1、電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)熱(re)器(qi)：電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)熱(re)器(qi)是種(zhong)利用(yong)電(dian)(dian)(dian)(dian)(dian)磁感(gan)應(ying)原理將(jiang)電(dian)(dian)(dian)(dian)(dian)能轉化成熱(re)能的(de)裝置，電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)熱(re)控制器(qi)將(jiang)220V，50/60HZ的(de)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)整流(liu)(liu)變成直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，再將(jiang)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉成頻(pin)率為20-40KHZ的(de)高(gao)頻(pin)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)，或者是380v 50/60HZ的(de)三相交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉換成直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)再將(jiang)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉換成10~30KHZ的(de)高(gao)頻(pin)低(di)壓(ya)大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，用(yong)來(lai)工業產品加(jia)(jia)熱(re)。

2、電(dian)(dian)磁(ci)加(jia)熱圈(quan)：高(gao)(gao)速(su)變化(hua)的(de)(de)(de)高(gao)(gao)頻高(gao)(gao)壓(ya)電(dian)(dian)流(liu)(liu)流(liu)(liu)過(guo)線圈(quan)會產(chan)(chan)生(sheng)(sheng)(sheng)高(gao)(gao)速(su)變化(hua)的(de)(de)(de)交(jiao)變磁(ci)場，當用含鐵質容(rong)器(qi)放置上面時，容(rong)器(qi)表面即具切(qie)割(ge)交(jiao)變磁(ci)力線而在容(rong)器(qi)底部(bu)(bu)金屬(shu)部(bu)(bu)分產(chan)(chan)生(sheng)(sheng)(sheng)交(jiao)變的(de)(de)(de)電(dian)(dian)流(liu)(liu)（即渦流(liu)(liu)），渦流(liu)(liu)使(shi)容(rong)器(qi)底部(bu)(bu)的(de)(de)(de)載流(liu)(liu)子高(gao)(gao)速(su)無規則運動，載流(liu)(liu)子互相碰(peng)撞、摩擦而產(chan)(chan)生(sheng)(sheng)(sheng)熱能(neng)。從而起(qi)到(dao)加(jia)熱物品的(de)(de)(de)效果。即是通(tong)過(guo)把電(dian)(dian)能(neng)轉化(hua)為(wei)磁(ci)能(neng)，使(shi)被(bei)加(jia)熱鋼體表面產(chan)(chan)生(sheng)(sheng)(sheng)感應渦流(liu)(liu)種(zhong)加(jia)熱方式(shi)。這種(zhong)方式(shi)從根本上解(jie)決(jue)了電(dian)(dian)熱片、電(dian)(dian)熱圈(quan)等電(dian)(dian)阻式(shi)的(de)(de)(de)，通(tong)過(guo)熱傳(chuan)導方式(shi)加(jia)熱產(chan)(chan)生(sheng)(sheng)(sheng)的(de)(de)(de)熱效率低下的(de)(de)(de)問題。
