紅外線發熱(re)管(guan)從外觀上(shang)看(kan)起來就像是一個更精(jing)致(zhi)小巧的(de)(de)燈管(guan),不過它的(de)(de)功能(neng)可(ke)不是發光,而是為了發熱(re),還能(neng)在緊湊的(de)(de)體積下達到比較大(da)的(de)(de)功率,既可(ke)以用(yong)在家(jia)用(yong)電器上(shang),也可(ke)以用(yong)在工業產品(pin)(pin)上(shang)。而作為一種電氣產品(pin)(pin),它在安裝(zhuang)的(de)(de)時候也要涉及到接線的(de)(de)問題,在這里為大(da)家(jia)介紹一下接線的(de)(de)方(fang)法與注意事項。
雖(sui)然(ran)在發(fa)熱(re)原理(li)上與傳統(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)熱(re)管(guan)(guan)并不一(yi)樣(yang),但它同(tong)樣(yang)可(ke)以歸為是一(yi)種電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)型的(de)(de)元件,所以是不用(yong)(yong)區分(fen)正(zheng)負極的(de)(de),如果是用(yong)(yong)直流來(lai)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian),只要(yao)(yao)把(ba)發(fa)熱(re)管(guan)(guan)的(de)(de)兩端接(jie)在兩個電(dian)(dian)(dian)(dian)(dian)(dian)極上即(ji)可(ke),無(wu)論接(jie)正(zheng)負極都可(ke)以正(zheng)常工作。而在強電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)當中,它也同(tong)樣(yang)不需要(yao)(yao)區分(fen)火線(xian)(xian)和零(ling)線(xian)(xian),無(wu)論怎樣(yang)接(jie)都能(neng)正(zheng)常發(fa)熱(re),而且也能(neng)正(zheng)常控制。但從安全用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)角度來(lai)說,在給發(fa)熱(re)管(guan)(guan)接(jie)線(xian)(xian)的(de)(de)時候(hou),還是有(you)必要(yao)(yao)區分(fen)一(yi)下火線(xian)(xian)零(ling)線(xian)(xian),做到統(tong)一(yi)和明確,這樣(yang)可(ke)以防止(zhi)斷電(dian)(dian)(dian)(dian)(dian)(dian)之后發(fa)熱(re)管(guan)(guan)依然(ran)帶電(dian)(dian)(dian)(dian)(dian)(dian),同(tong)時也方便(bian)日(ri)后的(de)(de)檢(jian)修維護。
需(xu)要強調的(de)(de)是(shi)(shi)(shi)工(gong)業(ye)環(huan)境(jing)下(xia)(xia)的(de)(de)接線(xian)(xian)方(fang)法(fa)(fa),比(bi)如工(gong)廠(chang)當中需(xu)要加熱的(de)(de)設備使用紅(hong)外線(xian)(xian)發熱管,接線(xian)(xian)的(de)(de)方(fang)式與家庭(ting)環(huan)境(jing)下(xia)(xia)完全不一(yi)樣。主要因為工(gong)業(ye)用電(dian)是(shi)(shi)(shi)380伏的(de)(de)三(san)相供電(dian),常規的(de)(de)方(fang)式是(shi)(shi)(shi)采(cai)用三(san)角形接線(xian)(xian)法(fa)(fa)。也(ye)就(jiu)(jiu)是(shi)(shi)(shi)要把三(san)個(ge)或三(san)組發熱管以三(san)角形的(de)(de)方(fang)式首位連(lian)接在(zai)一(yi)起(qi),而三(san)個(ge)相線(xian)(xian)分別(bie)接在(zai)三(san)角形的(de)(de)定(ding)點上,這樣才能正常工(gong)作。當然既(ji)然是(shi)(shi)(shi)連(lian)接在(zai)一(yi)起(qi),就(jiu)(jiu)要求發熱管的(de)(de)型號(hao)是(shi)(shi)(shi)完全一(yi)致的(de)(de)。
以上簡單介紹了紅外線(xian)(xian)(xian)發(fa)熱管的(de)(de)(de)接(jie)線(xian)(xian)(xian)方法與(yu)注意(yi)事項。在接(jie)線(xian)(xian)(xian)的(de)(de)(de)過(guo)程當(dang)中(zhong),一定要(yao)(yao)嚴格遵循安全用電的(de)(de)(de)規范,并且(qie)采用合適的(de)(de)(de)工具。所有的(de)(de)(de)接(jie)線(xian)(xian)(xian)部位都要(yao)(yao)做好絕緣保護,以防止在使用過(guo)程當(dang)中(zhong)發(fa)生漏電或(huo)者起火的(de)(de)(de)風險。
