點(dian)火器在修理閃光燈工作中應(ying)用的具體方法如下。

一(yi)、檢(jian)(jian)測氖(nai)(nai)泡(pao)(pao)      將氖(nai)(nai)泡(pao)(pao)串(chuan)聯(lian)一(yi)只0.001μF的(de)電(dian)(dian)(dian)(dian)容或10MΩ的(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)（若不(bu)易購(gou)到，可(ke)用2MΩ的(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)串(chuan)聯(lian)獲得(de)）后(hou)，與電(dian)(dian)(dian)(dian)子點火(huo)(huo)器或壓(ya)電(dian)(dian)(dian)(dian)打火(huo)(huo)機心的(de)高壓(ya)輸出端相(xiang)連(lian)，然后(hou)接(jie)通電(dian)(dian)(dian)(dian)子點火(huo)(huo)器的(de)電(dian)(dian)(dian)(dian)源或撳動壓(ya)電(dian)(dian)(dian)(dian)打火(huo)(huo)機心，在這同(tong)時(shi)觀(guan)察氖(nai)(nai)泡(pao)(pao)是(shi)否發光。如(ru)果氖(nai)(nai)泡(pao)(pao)發出桔紅色(se)閃(shan)光，說明氖(nai)(nai)泡(pao)(pao)完(wan)好，否則為(wei)漏氣損壞。串(chuan)聯(lian)電(dian)(dian)(dian)(dian)容或電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)為(wei)了防(fang)止脈沖高壓(ya)損壞氖(nai)(nai)泡(pao)(pao)。在用壓(ya)電(dian)(dian)(dian)(dian)打火(huo)(huo)機心檢(jian)(jian)測氖(nai)(nai)泡(pao)(pao)時(shi)，也可(ke)不(bu)串(chuan)聯(lian)電(dian)(dian)(dian)(dian)容或電(dian)(dian)(dian)(dian)阻(zu)(zu)。因為(wei)單脈沖高壓(ya)能量不(bu)大(da)，作用時(shi)間又(you)極(ji)短(duan)，尚不(bu)致損壞氖(nai)(nai)泡(pao)(pao)。

二、檢測閃(shan)光燈(deng)(deng)(deng)管      將電子點(dian)火器或壓(ya)電打(da)火機(ji)心(xin)(xin)高(gao)壓(ya)輸出的(de)(de)正(zheng)負端分別(bie)和閃(shan)光燈(deng)(deng)(deng)管的(de)(de)陰陽(yang)極相連。接(jie)通電子點(dian)火器的(de)(de)電源或撳動(dong)壓(ya)電打(da)火機(ji)心(xin)(xin)，兩極間應(ying)有(you)電弧(hu)跳過。否則為(wei)燈(deng)(deng)(deng)管漏氣(qi)。有(you)的(de)(de)燈(deng)(deng)(deng)管雖有(you)電弧(hu)跳過，卻不會閃(shan)亮，那是衰老了。可按(an)下述(shu)方(fang)法測定燈(deng)(deng)(deng)管衰老的(de)(de)程度。

三、測(ce)定(ding)燈管(guan)的(de)(de)起(qi)閃(shan)(shan)電(dian)(dian)壓(ya)(ya)      起(qi)閃(shan)(shan)電(dian)(dian)壓(ya)(ya)是燈管(guan)在施加觸發(fa)高(gao)(gao)壓(ya)(ya)下發(fa)生(sheng)閃(shan)(shan)光(guang)所需的(de)(de)最 低電(dian)(dian)壓(ya)(ya)，它和燈管(guan)的(de)(de)新舊(jiu)程度有(you)關。通(tong)常新燈管(guan)的(de)(de)起(qi)閃(shan)(shan)電(dian)(dian)壓(ya)(ya)在160V左右(you)。隨著使用次數的(de)(de)增加，起(qi)閃(shan)(shan)電(dian)(dian)壓(ya)(ya)逐漸升高(gao)(gao)。當(dang)升高(gao)(gao)到(dao)300V左右(you)時(shi)，閃(shan)(shan)光(guang)燈會出(chu)現(xian)(xian)有(you)時(shi)閃(shan)(shan)有(you)時(shi)不閃(shan)(shan)的(de)(de)現(xian)(xian)象。而當(dang)起(qi)閃(shan)(shan)電(dian)(dian)壓(ya)(ya)超過(guo)330V時(shi)就(jiu)不能觸發(fa)閃(shan)(shan)亮。這時(shi)就(jiu)判定(ding)為燈管(guan)衰老損壞了。

測(ce)定(ding)燈(deng)(deng)管(guan)(guan)的(de)起閃(shan)電(dian)(dian)壓(ya)(ya)要用電(dian)(dian)子點火(huo)器(qi)(qi)(qi)(qi)，具體做(zuo)法是(shi)：將(jiang)連接(jie)燈(deng)(deng)管(guan)(guan)觸(chu)(chu)發極(ji)的(de)接(jie)線，從閃(shan)光燈(deng)(deng)觸(chu)(chu)發變壓(ya)(ya)器(qi)(qi)(qi)(qi)高壓(ya)(ya)輸(shu)(shu)出端(duan)處焊開，接(jie)到電(dian)(dian)子點火(huo)器(qi)(qi)(qi)(qi)脈沖高壓(ya)(ya)輸(shu)(shu)出正端(duan)，再將(jiang)電(dian)(dian)子點火(huo)器(qi)(qi)(qi)(qi)脈沖高壓(ya)(ya)輸(shu)(shu)出負(fu)端(duan)和燈(deng)(deng)管(guan)(guan)的(de)陰極(ji)（或儲能電(dian)(dian)容的(de)負(fu)極(ji)）相(xiang)連，這樣就用電(dian)(dian)子點火(huo)器(qi)(qi)(qi)(qi)取(qu)代了閃(shan)光燈(deng)(deng)原來的(de)觸(chu)(chu)發電(dian)(dian)路(lu)。

最后(hou)在燈(deng)(deng)管的(de)陰陽(yang)極（或儲能電(dian)容的(de)正負極）之間(jian)跨接(jie)一塊量程(cheng)為soov的(de)直流電(dian)壓(ya)表，如附圖所(suo)示(shi)。接(jie)線完成后(hou)分別接(jie)通電(dian)子(zi)點火器和閃(shan)光燈(deng)(deng)的(de)電(dian)源。這(zhe)時(shi)(shi)(shi)電(dian)子(zi)點火器便不(bu)斷地(di)產生脈沖高壓(ya)，而閃(shan)光燈(deng)(deng)則(ze)對儲能電(dian)容充電(dian)。當儲能電(dian)容的(de)電(dian)壓(ya)升高到一定(ding)程(cheng)度時(shi)(shi)(shi)，燈(deng)(deng)管便閃(shan)亮。這(zhe)時(shi)(shi)(shi)的(de)電(dian)壓(ya)便是燈(deng)(deng)管的(de)起閃(shan)電(dian)壓(ya)，其數(shu)值可從(cong)電(dian)壓(ya)表上讀出。

對(dui)于充(chong)電(dian)正(zheng)常而且(qie)儲(chu)能電(dian)容和燈(deng)(deng)管之(zhi)間接(jie)線完好卻不能閃(shan)亮的閃(shan)光燈(deng)(deng)，可試用電(dian)子點火器或(huo)(huo)壓電(dian)打火機心引(yin)燃燈(deng)(deng)管，從而判斷(duan)閃(shan)光燈(deng)(deng)的觸發電(dian)路是否有故(gu)障(zhang)或(huo)(huo)燈(deng)(deng)管是否損(sun)壞(huai)。試驗時接(jie)線同上，電(dian)壓表也可不用。

所不同的是：要先接通閃光燈的龜源使儲能電容充電，然后再接通電子點火器的電源或撳動壓電打火機心產生脈沖高壓。如果燈管是完好的，這時就會閃亮。而原來閃光燈不亮是觸發電路發生了故障，可進一步查找原因。如果燈管不亮，則是損壞了，在更換燈管恢復線路后便能閃亮。實踐證明，用脈沖高壓點火器測定燈(deng)(deng)管的起(qi)閃(shan)(shan)電壓或(huo)引(yin)燃(ran)燈(deng)(deng)管，小(xiao)至機載閃(shan)(shan)光(guang)燈(deng)(deng)，大至影室(shi)專用(yong)的高功率(lv)電子傘燈(deng)(deng)均行(xing)之有效。因(yin)而是(shi)閃(shan)(shan)光(guang)燈(deng)(deng)修理工作中最(zui)為方(fang)便有用(yong)的方(fang)法(fa)。
