一、產(chan)品簡(jian)介：

冠宇(yu)臭氧發(fa)生(sheng)(sheng)器(qi)是冠宇(yu)設備公司依靠自身技術綜合(he)實力，廣泛結合(he)國內外發(fa)生(sheng)(sheng)器(qi)的(de)技術，開發(fa)生(sheng)(sheng)產的(de)高(gao)科技產品，該產品分為氧氣型和(he)空氣型兩大類，集中(zhong)性(xing)好、具有高(gao)穩定(ding)性(xing)、高(gao)產氣量(liang)、高(gao)濃度、低電(dian)耗、操作簡便等(deng)特點。

2、電源系統(tong)的設計

  臭氧電(dian)(dian)(dian)源(yuan)設計(ji)是根據臭氧產量和放電(dian)(dian)(dian)單元臭氧產量所耗功率(lv)來設計(ji),電(dian)(dian)(dian)源(yuan)頻(pin)率(lv)、電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓與使用介質 ,放電(dian)(dian)(dian)氣隙大小(xiao)有關.可根據有條件(jian)的實驗數據獲得.

臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)包括電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)控制系(xi)(xi)(xi)統(tong)、整流、變頻(pin)(pin)器、升壓變壓器，它的作用就是向臭(chou)(chou)(chou)氧(yang)(yang)放電(dian)(dian)(dian)(dian)室提供(gong)必要條件—高(gao)壓交變電(dian)(dian)(dian)(dian)場，而臭(chou)(chou)(chou)氧(yang)(yang)產生效率與高(gao)壓電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)成正向增長(chang)關系(xi)(xi)(xi)，因(yin)此臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)在整個臭(chou)(chou)(chou)氧(yang)(yang)發生系(xi)(xi)(xi)統(tong)中(zhong)具(ju)有(you)重要的作用。臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)依據高(gao)壓放電(dian)(dian)(dian)(dian)頻(pin)(pin)率可分為工(gong)頻(pin)(pin)臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)、中(zhong)頻(pin)(pin)臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)、高(gao)頻(pin)(pin)臭(chou)(chou)(chou)氧(yang)(yang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)系(xi)(xi)(xi)統(tong)三(san)類，其中(zhong)頻(pin)(pin)率為 60/50Hz 的電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)稱為工(gong)頻(pin)(pin)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，頻(pin)(pin)率超過(guo) 1000Hz 的電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)稱為高(gao)頻(pin)(pin)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，介(jie)于工(gong)頻(pin)(pin)與高(gao)頻(pin)(pin)之間的稱為中(zhong)頻(pin)(pin)。

1）工(gong)頻(pin)臭氧電(dian)源系統(tong)

  工頻臭氧電源系統的工作原理：交流 380V 電壓經高壓變壓器后，變壓器輸出交流 10000V 電壓供給臭氧合成系統。其結構圖如下所示：

  工頻臭(chou)氧(yang)電源系統(tong)需(xu)要漏(lou)感很大(da)的(de)高(gao)壓變壓器(qi)、效率(lv)低、耗電大(da)、產生臭(chou)氧(yang)的(de)產量(liang)與濃(nong)度(du)低；一般采用玻璃管(guan)作放電介電體，用于生產中、大(da)型臭(chou)氧(yang)發生器(qi)。

2 ）中(zhong)頻臭(chou)氧電源(yuan)系統

中頻臭氧電源系統的電路結構圖，此電源是根據介質和臭氧放電室而設計的與之相匹配的高壓電源，其中可控硅屬大功率器件，工作壓降低，過載特性好，輸出功率大，用于中頻大功率電源時的性能比較高，能很好地滿足臭氧發生器對電源的需要。 

A．三(san)相全控整流橋(qiao)

  用于(yu)控制調(diao)節整(zheng)流器(qi)的輸出(chu)電(dian)(dian)(dian)壓，實現高壓輸出(chu)電(dian)(dian)(dian)壓與臭(chou)(chou)氧(yang)產(chan)(chan)量的平滑調(diao)節。該電(dian)(dian)(dian)路能(neng)避免臭(chou)(chou)氧(yang)放電(dian)(dian)(dian)室(shi)在起輝和工(gong)作放電(dian)(dian)(dian)時因負(fu)載變動產(chan)(chan)生(sheng)高電(dian)(dian)(dian)壓，從而(er)保證(zheng)了臭(chou)(chou)氧(yang)電(dian)(dian)(dian)源和臭(chou)(chou)氧(yang)放電(dian)(dian)(dian)室(shi)的可(ke)靠性。

B．可控硅(gui)全橋(qiao)逆變

  因可(ke)控(kong)(kong)(kong)硅(gui)是半開關器件，它必(bi)須在(zai)自身電(dian)流(liu)過(guo)零時(shi)才能關斷，而可(ke)控(kong)(kong)(kong)硅(gui)又在(zai)電(dian)源與負(fu)(fu)(fu)載(zai)之間作開關使用(yong)(yong)，可(ke)控(kong)(kong)(kong)硅(gui)一旦打開就失(shi)去了控(kong)(kong)(kong)制電(dian)流(liu)大小的(de)作用(yong)(yong)。因此(ci)電(dian)流(liu)的(de)大小和(he)相位受前級(ji)和(he)負(fu)(fu)(fu)載(zai)影(ying)響(xiang)，為(wei)(wei)保證(zheng)可(ke)控(kong)(kong)(kong)硅(gui)正(zheng)常關斷，要求(qiu)在(zai)可(ke)控(kong)(kong)(kong)硅(gui)自身電(dian)流(liu)過(guo)零時(shi)其兩端電(dian)壓為(wei)(wei)零或已變(bian)(bian)為(wei)(wei)負(fu)(fu)(fu)值，這(zhe)在(zai)臭氧放電(dian)室(shi)這(zhe)一負(fu)(fu)(fu)載(zai)下很難實現，而且(qie)在(zai)起輝、正(zheng)常工作、瞬時(shi)跳火(huo)或局部(bu)跳火(huo)時(shi)負(fu)(fu)(fu)載(zai)特性變(bian)(bian)化很大，這(zhe)地影(ying)響(xiang)了可(ke)控(kong)(kong)(kong)硅(gui)的(de)正(zheng)常關斷。為(wei)(wei)了保證(zheng)可(ke)控(kong)(kong)(kong)硅(gui)的(de)正(zheng)常關斷，有受負(fu)(fu)(fu)載(zai)影(ying)響(xiang)較小的(de)關斷電(dian)路與之相匹配。

C．濾波(bo)電路(lu)

  由電抗器、電容組成的濾波電路，用于提高功率因數，平滑輸出電流，穩定(ding)逆(ni)變(bian)器的工作(zuo)點，抑制逆(ni)變(bian)雜(za)波，減小對(dui)電源網(wang)絡的干擾。

D．吸收回路

 由電(dian)(dian)容(rong)、電(dian)(dian)阻組成(cheng)的緩沖電(dian)(dian)路，可以防止過壓，保(bao)護可控硅(gui)和其他元器件的正常工作。

E．高壓變壓器

高壓(ya)(ya)變(bian)(bian)壓(ya)(ya)器(qi)用(yong)于(yu)傳遞(di)功(gong)率和(he)使(shi)電(dian)子(zi)功(gong)率電(dian)路的(de)輸(shu)出與放(fang)電(dian)室匹配，對其參數的(de)要求與普(pu)通(tong)變(bian)(bian)壓(ya)(ya)器(qi)有(you)所區(qu)別。由于(yu)放(fang)電(dian)室在(zai)整個工作過程中，負載不(bu)僅在(zai)數值上變(bian)(bian)化很(hen)大，其特性也隨著起輝或正常工作時(shi)的(de)狀態不(bu)同(tong)而改變(bian)(bian)，從而要求變(bian)(bian)壓(ya)(ya)器(qi)有(you)一定的(de)漏感(gan)來平衡上述變(bian)(bian)化，以便保護(hu)電(dian)子(zi)元器(qi)件。同(tong)時(shi)，漏感(gan)又容易引起電(dian)路損耗和(he)換相(xiang)時(shi)產生瞬時(shi)高電(dian)壓(ya)(ya)，因此需要

根據(ju)電子(zi)電路的情況選擇其大小(xiao)。

中(zhong)頻臭氧(yang)電(dian)源是(shi)上比較(jiao)流行的一種臭氧(yang)電(dian)源，具有(you)效率高、耗(hao)電(dian)小(xiao)的特點。一般采用非玻璃或玻璃作放電(dian)介電(dian)體，用于生(sheng)產中(zhong)、大型臭氧(yang)發生(sheng)器。
