隨著紫外線(xian)殺菌燈(deng)(deng)應用(yong)領域不(bu)斷(duan)擴大(da),為(wei)了(le)能夠讓(rang)使用(yong)紫外線(xian)燈(deng)(deng)得到最(zui)大(da)化(hua)的發展,所(suo)以現在(zai)的紫外線(xian)燈(deng)(deng)配置了(le)專用(yong)電子(zi)鎮(zhen)流器,大(da)大(da)提(ti)高了(le)紫外線(xian)燈(deng)(deng)的強度輸出。你知道電子(zi)鎮(zhen)流器在(zai)紫外線(xian)殺菌燈(deng)(deng)中的作用(yong)嗎?鎮(zhen)流器的選擇有哪些注意事項嗎?
1、什(shen)么是紫外線殺菌燈鎮流器?
鎮流(liu)器,簡單地說是金屬導電(dian)線(xian)圈。可在低頻率或高頻率下工作(zuo)。因(yin)為線(xian)圈的熱損(sun)失小,所以(yi)較電(dian)阻有效。能起到限流(liu)與產生瞬間(jian)高壓的作(zuo)用(yong)。
最早出現,結(jie)構(gou)較為(wei)簡單。電(dian)(dian)感(gan)(gan)鎮流(liu)器是利用(yong)電(dian)(dian)感(gan)(gan)的(de)(de)感(gan)(gan)抗(kang)和(he)自(zi)感(gan)(gan)電(dian)(dian)動(dong)勢來點亮氣體放電(dian)(dian)燈(deng)的(de)(de),自(zi)感(gan)(gan)電(dian)(dian)動(dong)勢“擊(ji)穿”燈(deng)管(guan)的(de)(de)氣體啟動(dong)燈(deng)管(guan),電(dian)(dian)感(gan)(gan)限(xian)制(zhi)燈(deng)管(guan)電(dian)(dian)流(liu)不(bu)使其燒毀。由于電(dian)(dian)子(zi)鎮流(liu)器具有節能降耗,低壓啟動(dong)迅速,功(gong)率(lv)因數高(gao)等優點,且紫外線(xian)殺菌(jun)燈(deng)使用(yong)壽命大大延長。傳(chuan)統的(de)(de)電(dian)(dian)感(gan)(gan)鎮流(liu)器逐步(bu)換成專用(yong)的(de)(de)電(dian)(dian)子(zi)鎮流(liu)器,雖然(ran)成本有所提高(gao),但是從長遠來看(kan),其潛在的(de)(de)經(jing)濟效益卻非常可觀。
2、紫外線殺菌(jun)燈鎮流器的(de)作用
(1)產生高壓,起輝燈管打(da)破(po)燈內的稀有氣(qi)體(ti)。
(2)殺菌燈(deng)管(guan)起輝后(hou)起鎮流(限流)作用(yong),使燈(deng)管(guan)正常穩定地(di)工作。氣體放電(dian)(dian)(dian)(dian)燈(deng)都有(you)較高(gao)的(de)(de)啟(qi)(qi)動電(dian)(dian)(dian)(dian)壓(ya)和低(di)放電(dian)(dian)(dian)(dian)維持(chi)電(dian)(dian)(dian)(dian)壓(ya).當燈(deng)通過高(gao)壓(ya)啟(qi)(qi)動后,電(dian)(dian)(dian)(dian)壓(ya)下降,電(dian)(dian)(dian)(dian)流(liu)(liu)加大,如不(bu)加限制,燈(deng)電(dian)(dian)(dian)(dian)流(liu)(liu)將不(bu)斷(duan)加大直至(zhi)使(shi)燈(deng)燒毀(hui),所以必需在放電(dian)(dian)(dian)(dian)燈(deng)的(de)(de)點燈(deng)回路(lu)中串接一個與燈(deng)的(de)(de)類型、規(gui)格匹配的(de)(de)鎮(zhen)流(liu)(liu)器提供使(shi)燈(deng)啟(qi)(qi)動的(de)(de)高(gao)啟(qi)(qi)動電(dian)(dian)(dian)(dian)壓(ya),并限制燈(deng)電(dian)(dian)(dian)(dian)流(liu)(liu)使(shi)之穩定(ding)在所規(gui)定(ding)的(de)(de)范(fan)圍。
3、使(shi)用(yong)紫(zi)外(wai)線殺(sha)菌(jun)燈(deng)鎮(zhen)流(liu)器注意事(shi)項
(1)瞬時啟(qi)動(dong)V.S.延時啟(qi)動(dong)
匹配小(xiao)功率(lv)燈(deng)(deng)管(guan)時,影響還不太明顯,不過(guo)匹配大(da)功率(lv)紫外線(xian)殺(sha)菌燈(deng)(deng)(比如120W,150W及320W等)時,瞬時啟(qi)動對紫外線(xian)燈(deng)(deng)使用(yong)壽命影響非常大(da)。這是(shi)由于紫外線(xian)殺(sha)菌燈(deng)(deng)在啟(qi)動時,所需的(de)啟(qi)動電流(liu)非常大(da),容易(yi)擊(ji)穿燈(deng)(deng)管(guan),而延(yan)時啟(qi)動,通過(guo)蓄能減少瞬時壓(ya)力,對燈(deng)(deng)管(guan)起到更好的(de)保護(hu)作用(yong)。
(2)選擇適(shi)配
一定要選擇(ze)適配的型號(hao)。既然(ran)鎮(zhen)(zhen)流器的核心功(gong)能是保護紫(zi)外線殺(sha)菌燈管,延長(chang)使用壽命。若選擇(ze)的鎮(zhen)(zhen)流器與的燈管參數不匹(pi)配,兩(liang)方(fang)都是受害(hai)者。
