隨著(zhu)紫(zi)外(wai)(wai)(wai)線(xian)殺(sha)菌燈(deng)應用領(ling)域不(bu)斷擴(kuo)大,為(wei)了能(neng)夠(gou)讓使用紫(zi)外(wai)(wai)(wai)線(xian)燈(deng)得到最大化(hua)的(de)(de)發(fa)展(zhan),所以現(xian)在(zai)的(de)(de)紫(zi)外(wai)(wai)(wai)線(xian)燈(deng)配置了專用電子鎮(zhen)流器(qi),大大提高了紫(zi)外(wai)(wai)(wai)線(xian)燈(deng)的(de)(de)強(qiang)度輸出。你知道電子鎮(zhen)流器(qi)在(zai)紫(zi)外(wai)(wai)(wai)線(xian)殺(sha)菌燈(deng)中的(de)(de)作(zuo)用嗎?鎮(zhen)流器(qi)的(de)(de)選擇有哪些注意(yi)事項嗎?

1、什(shen)么是紫外線殺菌燈鎮(zhen)流器?

鎮流器,簡單地說(shuo)是金屬導電線圈。可在(zai)低頻率(lv)或高頻率(lv)下(xia)工(gong)作。因為線圈的熱損(sun)失小,所(suo)以(yi)較電阻(zu)有(you)效(xiao)。能起到限流與產生瞬間高壓的作用。

最早出現,結構(gou)較為簡單(dan)。電(dian)(dian)(dian)感(gan)鎮(zhen)(zhen)流(liu)(liu)(liu)器(qi)是(shi)利用(yong)電(dian)(dian)(dian)感(gan)的感(gan)抗(kang)和自(zi)感(gan)電(dian)(dian)(dian)動(dong)(dong)勢(shi)來(lai)點亮氣體放電(dian)(dian)(dian)燈的,自(zi)感(gan)電(dian)(dian)(dian)動(dong)(dong)勢(shi)“擊穿”燈管的氣體啟動(dong)(dong)燈管,電(dian)(dian)(dian)感(gan)限制燈管電(dian)(dian)(dian)流(liu)(liu)(liu)不使其燒(shao)毀。由于(yu)電(dian)(dian)(dian)子(zi)鎮(zhen)(zhen)流(liu)(liu)(liu)器(qi)具有(you)節能降耗,低壓啟動(dong)(dong)迅速(su),功(gong)率(lv)因數高等優點,且紫外線(xian)殺菌燈使用(yong)壽命大(da)大(da)延(yan)長。傳統的電(dian)(dian)(dian)感(gan)鎮(zhen)(zhen)流(liu)(liu)(liu)器(qi)逐步(bu)換成(cheng)專用(yong)的電(dian)(dian)(dian)子(zi)鎮(zhen)(zhen)流(liu)(liu)(liu)器(qi),雖然成(cheng)本(ben)有(you)所提高,但(dan)是(shi)從長遠來(lai)看,其潛(qian)在的經濟效(xiao)益卻非常可觀。

2、紫外線(xian)殺菌(jun)燈鎮流(liu)器的作用

(1)產生高(gao)壓,起輝燈管打(da)破燈內(nei)的稀有(you)氣體。

(2)殺菌燈(deng)管(guan)起(qi)輝后起(qi)鎮流(限流)作(zuo)用,使燈(deng)管(guan)正常穩定(ding)地工作(zuo)。氣體放(fang)電(dian)(dian)(dian)燈(deng)(deng)都有較(jiao)高(gao)的(de)啟(qi)動(dong)電(dian)(dian)(dian)壓和低放(fang)電(dian)(dian)(dian)維持電(dian)(dian)(dian)壓.當(dang)燈(deng)(deng)通過高(gao)壓啟(qi)動(dong)后,電(dian)(dian)(dian)壓下降(jiang),電(dian)(dian)(dian)流(liu)加大,如不加限制,燈(deng)(deng)電(dian)(dian)(dian)流(liu)將不斷(duan)加大直至使燈(deng)(deng)燒(shao)毀,所(suo)以必(bi)需在放(fang)電(dian)(dian)(dian)燈(deng)(deng)的(de)點燈(deng)(deng)回路中串接一(yi)個與(yu)燈(deng)(deng)的(de)類(lei)型、規格匹配(pei)的(de)鎮流(liu)器提供使燈(deng)(deng)啟(qi)動(dong)的(de)高(gao)啟(qi)動(dong)電(dian)(dian)(dian)壓,并限制燈(deng)(deng)電(dian)(dian)(dian)流(liu)使之穩定(ding)在所(suo)規定(ding)的(de)范圍。

3、使用紫外線殺菌燈鎮流器(qi)注意(yi)事項

(1)瞬時啟動(dong)V.S.延時啟動(dong)

匹配小功(gong)(gong)率燈(deng)管時(shi)(shi),影(ying)響(xiang)還不太明顯,不過匹配大(da)功(gong)(gong)率紫(zi)(zi)外(wai)(wai)線殺菌燈(deng)(比如(ru)120W,150W及320W等)時(shi)(shi),瞬時(shi)(shi)啟(qi)動對紫(zi)(zi)外(wai)(wai)線燈(deng)使用壽命(ming)影(ying)響(xiang)非常大(da)。這是由于紫(zi)(zi)外(wai)(wai)線殺菌燈(deng)在啟(qi)動時(shi)(shi),所需的(de)(de)啟(qi)動電流(liu)非常大(da),容易擊(ji)穿燈(deng)管,而延時(shi)(shi)啟(qi)動,通過蓄(xu)能減少瞬時(shi)(shi)壓力,對燈(deng)管起(qi)到更好的(de)(de)保護作用。

(2)選擇適配(pei)

一定要選擇適配(pei)的型號。既然鎮(zhen)流器(qi)的核心功(gong)能是保護紫外線殺菌燈(deng)管,延(yan)長使用壽命。若選擇的鎮(zhen)流器(qi)與(yu)的燈(deng)管參數(shu)不匹配(pei),兩方都是受害者。
