臭(chou)氧是(shi)一種不穩定的氣體，不能(neng)儲存運輸，因此臭(chou)氧必須在(zai)使(shi)用(yong)(yong)(yong)現(xian)場(chang)發生(sheng)制備。臭(chou)氧具有很(hen)強的氧化(hua)(hua)性(xing)，臭(chou)氧化(hua)(hua)空(kong)(kong)氣幾乎對所(suo)有的金屬都(dou)有腐(fu)蝕(shi)作用(yong)(yong)(yong)。臭(chou)氧技術已(yi)在(zai)污水處理、醫學(xue)、食品、化(hua)(hua)工生(sheng)產、空(kong)(kong)氣凈化(hua)(hua)、飲用(yong)(yong)(yong)水殺菌(jun)消毒等領域得(de)到(dao)廣泛(fan)應用(yong)(yong)(yong)。那(nei)么臭(chou)氧發生(sheng)器(qi)的電(dian)路(lu)圖如圖所(suo)示：

臭氧(yang)發(fa)(fa)生器(qi)(qi)電(dian)(dian)(dian)路(lu)由(you)三極(ji)管VT1、VT2與(yu)電(dian)(dian)(dian)感(gan)線(xian)圈L1一13、脈(mo)沖變壓器(qi)(qi)T、限流(liu)電(dian)(dian)(dian)阻器(qi)(qi)R1、充電(dian)(dian)(dian)電(dian)(dian)(dian)容器(qi)(qi)C3,雙(shuang)向觸發(fa)(fa)二極(ji)管叨(tao)5等組(zu)成推(tui)挽(wan)振(zhen)蕩電(dian)(dian)(dian)路(lu)；濾(lv)(lv)波電(dian)(dian)(dian)感(gan)線(xian)圈L0,整流(liu)二極(ji)管VD1與(yu)濾(lv)(lv)波電(dian)(dian)(dian)容器(qi)(qi)C1、C2等組(zu)成半(ban)波整流(liu)濾(lv)(lv)波電(dian)(dian)(dian)路(lu)。 接通電(dian)(dian)(dian)源，交流(liu)220V電(dian)(dian)(dian)壓經LO濾(lv)(lv)波，VD1整流(liu)后(hou)，在C1兩(liang)端產(chan)生十280V左右的電(dian)(dian)(dian)壓，供(gong)給推(tui)挽(wan)振(zhen)蕩電(dian)(dian)(dian)路(lu)。 在開機瞬間(jian)，VT1導(dao)(dao)通。由(you)于C3的充電(dian)(dian)(dian)作用，雙(shuang)向觸發(fa)(fa)二極(ji)管VD5截止。當C3兩(liang)端的充電(dian)(dian)(dian)電(dian)(dian)(dian)壓升至32V時(shi)，VD5被觸發(fa)(fa)而導(dao)(dao)通，使VT2導(dao)(dao)通。

在(zai)VT2導通期(qi)間，C3逐漸放(fang)電，又使(shi)VT2截止。VTl導通后(hou)，在(zai)脈沖(chong)變壓器T的(de)作用下，L1、L2上產(chan)生(sheng)正反饋電壓，此電壓分(fen)別(bie)加至VTl和VT2的(de)基極，使(shi)VTl和VT2交替導通與截止（即VTl導通時(shi)(shi)，VT2截止；VT2導通時(shi)(shi)，VTl截止），推(tui)挽振蕩(dang)電路振蕩(dang)工作。 推(tui)挽振蕩(dang)電路工作后(hou)，在(zai)脈沖(chong)變壓器T的(de)二次側繞組(zu)L6上產(chan)生(sheng)脈沖(chong)高壓，使(shi)臭氧(yang)發生(sheng)片VG工作，產(chan)生(sheng)臭氧(yang)。

同(tong)時，發光二極管VD7也點亮(liang)工作(zuo)。 元器(qi)件選(xuan)擇 VTl、VT2選(xuan)用(yong)(yong)(yong)2SC2653或BU406型硅NPN高(gao)反壓(ya)三極管。要求電流放(fang)大系數β＞100。 VDl一VD4、VD6選(xuan)用(yong)(yong)(yong)1 N4007型整(zheng)流二極管；VD5選(xuan)用(yong)(yong)(yong)DB3型雙向觸(chu)發二極管。 R1一R6全部選(xuan)用(yong)(yong)(yong)RJ一1/8W型金屬(shu)膜電阻器(qi)。 L0為(wei)5mH的(de)磁心電感線(xian)圈(quan)，可用(yong)(yong)(yong)Φ0.25mm的(de)漆(qi)包線(xian)在骨架上繞(rao)210匝；L1一璐用(yong)(yong)(yong)Φ0.2mm的(de)單心塑銅(tong)線(xian)在同(tong)一磁環上繞(rao)制(zhi)而成，其(qi)中L1、L2分別繞(rao)3匝，L3繞(rao)9匝。脈沖變壓(ya)器(qi)T可使用(yong)(yong)(yong)14in（英寸）黑白(bai)電視機行輸出(chu)變壓(ya)器(qi)改制(zhi)，改制(zhi)時用(yong)(yong)(yong)高(gao)壓(ya)包作(zuo)為(wei)L6，在低壓(ya)包骨架上用(yong)(yong)(yong)Φ0.45mm的(de)漆(qi)包線(xian)繞(rao)168匝作(zuo)為(wei)L4，用(yong)(yong)(yong)Φ0.23mm的(de)漆(qi)包線(xian)繞(rao)4匝作(zuo)為(wei)L5（在最(zui)外層繞(rao)制(zhi)）。 

臭(chou)氧發(fa)生(sheng)(sheng)片VG選用Z二(er)10或Z一15、Z一20等型號(hao)。 制作與(yu)調試(shi) 除臭(chou)氧發(fa)生(sheng)(sheng)片VG外(wai)所有(you)電子元器件安(an)裝(zhuang)在(zai)(zai)一塊(kuai)自制的印制電路板上(shang)，并將其裝(zhuang)人大小合適的塑(su)料或木制盒(he)內。在(zai)(zai)盒(he)面(mian)開孔(kong)固定發(fa)光(guang)二(er)極(ji)管VD7，接(jie)上(shang)臭(chou)氧發(fa)生(sheng)(sheng)片VG，只要元器件良好(hao)、接(jie)線無誤(wu)，通電即能正常工作。
