捷德電子(zi)防爆閃(shan)光燈的工作原理解析：

電(dian)(dian)(dian)路(lu)由四部分(fen)(fen)組(zu)成:振(zhen)蕩升壓(ya)部分(fen)(fen)、整(zheng)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)部分(fen)(fen)、電(dian)(dian)(dian)壓(ya)指(zhi)(zhi)示(shi)部分(fen)(fen)和(he)脈沖(chong)觸(chu)發(fa)閃(shan)光(guang)(guang)部分(fen)(fen)。 當(dang)電(dian)(dian)(dian)源接通(tong)后(hou)，利用晶體管V1的(de)(de)(de)開關特性，形成一(yi)個間歇振(zhen)蕩，使T1的(de)(de)(de)初級(ji)(ji)獲得一(yi)個交(jiao)變電(dian)(dian)(dian)壓(ya)，經T1升壓(ya)，使其(qi)次級(ji)(ji)獲得大于300V的(de)(de)(de)交(jiao)變電(dian)(dian)(dian)壓(ya)。交(jiao)變電(dian)(dian)(dian)壓(ya)經二極管D1半波整(zheng)流(liu)(liu)后(hou)變成直流(liu)(liu)電(dian)(dian)(dian)壓(ya)，對主(zhu)電(dian)(dian)(dian)容C2和(he)觸(chu)發(fa)電(dian)(dian)(dian)容C3充(chong)(chong)電(dian)(dian)(dian)儲能(neng)。當(dang)電(dian)(dian)(dian)壓(ya)充(chong)(chong)至額定電(dian)(dian)(dian)壓(ya)的(de)(de)(de)70%左右(you)時(shi)，指(zhi)(zhi)示(shi)電(dian)(dian)(dian)路(lu)中的(de)(de)(de)氖燈(deng)(Ne)起(qi)輝，指(zhi)(zhi)示(shi)閃(shan)光(guang)(guang)燈(deng)處于正常閃(shan)光(guang)(guang)等待狀態。當(dang)按(an)下按(an)鈕AN，觸(chu)發(fa)電(dian)(dian)(dian)路(lu)(由R3、C3、T2和(he)Xe組(zu)成)產生脈沖(chong)電(dian)(dian)(dian)壓(ya)，在T2的(de)(de)(de)次級(ji)(ji)感應出瞬間高壓(ya)(約(yue)10kV)脈沖(chong)，通(tong)過Xe閃(shan)光(guang)(guang)管的(de)(de)(de)觸(chu)發(fa)極使Xe閃(shan)光(guang)(guang)管內氮(dan)氣電(dian)(dian)(dian)離并導通(tong)，電(dian)(dian)(dian)容C2上儲存的(de)(de)(de)電(dian)(dian)(dian)能(neng)瞬間通(tong)過閃(shan)光(guang)(guang)燈(deng)管放電(dian)(dian)(dian)轉(zhuan)化為(wei)光(guang)(guang)能(neng)，完成一(yi)次閃(shan)光(guang)(guang)。
