一(yi)、鋁合金陽極氧化、電鍍(du)電源
長期以來，人們對金(jin)屬表(biao)面(mian)(mian)處(chu)理過(guo)(guo)程，比較注重工藝(yi)技術、添加劑等方(fang)面(mian)(mian)的(de)改進和提高，與(yu)(yu)表(biao)面(mian)(mian)處(chu)理相關的(de)電源(yuan)的(de)性能和作(zuo)用往(wang)往(wang)放在(zai)次要方(fang)面(mian)(mian)。金(jin)屬表(biao)面(mian)(mian)形成和性能不(bu)僅(jin)與(yu)(yu)其工藝(yi)配方(fang)、添加劑有密切的(de)關系，而且與(yu)(yu)電源(yuan)技術水平(ping)息(xi)息(xi)相關，是工藝(yi)與(yu)(yu)設備(bei)配合的(de)結果。隨著我國鋁加工、金(jin)屬電鍍(du)、電泳涂裝等行(xing)業(ye)的(de)不(bu)斷發展，一個年銷售(shou)額超(chao)過(guo)(guo)200億人民幣的(de)鋁型(xing)材行(xing)業(ye)及年超(chao)過(guo)(guo)6億平(ping)方(fang)米電鍍(du)面(mian)(mian)積的(de)電鍍(du)工業(ye)已經(jing)形成，該類電力整流電源(yuan)的(de)需求(qiu)量是有相當(dang)可(ke)觀的(de)。
鋁合(he)金(jin)陽極氧(yang)化(hua)、電(dian)(dian)(dian)鍍電(dian)(dian)(dian)源(yuan)(yuan)(yuan)主(zhu)(zhu)要特(te)(te)點(dian)是：電(dian)(dian)(dian)流(liu)(liu)大、電(dian)(dian)(dian)壓低、功能(neng)(neng)較為(wei)簡(jian)單及(ji)使用環境相對較差。八十年代引進(jin)(jin)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)設(she)備(bei)有(you)(you)共同的(de)(de)(de)(de)(de)特(te)(te)點(dian)，就(jiu)是電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)形式采用可控硅整流(liu)(liu)。可控硅整流(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)具(ju)有(you)(you)節約(yue)能(neng)(neng)源(yuan)(yuan)(yuan)、控制(zhi)先進(jin)(jin)等特(te)(te)點(dian)。引進(jin)(jin)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)設(she)備(bei)各(ge)有(you)(you)特(te)(te)色(se)，意大利、西德的(de)(de)(de)(de)(de)氧(yang)化(hua)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)多(duo)(duo)為(wei)脈沖整流(liu)(liu)方式，日(ri)(ri)本、美(mei)國采用普通整流(liu)(liu)方式。在冷(leng)卻(que)設(she)計(ji)方面，西德、美(mei)國的(de)(de)(de)(de)(de)氧(yang)化(hua)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)以水冷(leng)為(wei)主(zhu)(zhu)，主(zhu)(zhu)變(bian)壓器和匯流(liu)(liu)母(mu)排都設(she)置了水冷(leng)管道，設(she)備(bei)的(de)(de)(de)(de)(de)密(mi)(mi)封性較好(hao)(hao)。日(ri)(ri)本、意大利卻(que)以風冷(leng)設(she)計(ji)，主(zhu)(zhu)變(bian)壓器和整流(liu)(liu)元(yuan)(yuan)件(jian)采用風冷(leng)，控制(zhi)線路(lu)有(you)(you)良好(hao)(hao)的(de)(de)(de)(de)(de)隔(ge)離密(mi)(mi)封，主(zhu)(zhu)變(bian)壓器經過嚴格的(de)(de)(de)(de)(de)絕緣密(mi)(mi)封處理，抗腐蝕性能(neng)(neng)好(hao)(hao)。以上(shang)產(chan)品使用中(zhong)各(ge)有(you)(you)千(qian)秋，總(zong)體來說使用性能(neng)(neng)良好(hao)(hao)，可靠性高。而臺灣產(chan)的(de)(de)(de)(de)(de)氧(yang)化(hua)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)主(zhu)(zhu)要用油冷(leng)方式，主(zhu)(zhu)變(bian)壓器甚至(zhi)硅元(yuan)(yuan)件(jian)也浸在絕緣油中(zhong)，整體密(mi)(mi)封性好(hao)(hao)。控制(zhi)線路(lu)是日(ri)(ri)本產(chan)品的(de)(de)(de)(de)(de)復制(zhi)品，元(yuan)(yuan)器件(jian)多(duo)(duo)為(wei)進(jin)(jin)口(kou)。由于產(chan)品設(she)計(ji)的(de)(de)(de)(de)(de)缺陷，使用中(zhong)的(de)(de)(de)(de)(de)缺點(dian)、故(gu)障(zhang)較多(duo)(duo)。
八十年代(dai)初我(wo)國整(zheng)流器(qi)行業受到大功(gong)率半道體制造水平(ping)(ping)及一(yi)貫(guan)設(she)計規范的制約，還(huan)處于發展較慢、技術水平(ping)(ping)落(luo)后階段。采用可控硅(gui)(gui)形式(shi)的整(zheng)流設(she)備較少。八十年代(dai)后期，國家機械工業部對表面處理電(dian)源(yuan)專門(men)列項進(jin)行研究(jiu)、公關。廣州電(dian)器(qi)科(ke)學研究(jiu)所作為承擔單位之一(yi)，通過了(le)解引進(jin)電(dian)源(yuan)在(zai)國內(nei)的使用情況，主(zhu)要解剖學習(xi)日本(ben)(例如三(san)社(she)、千代(dai)田等(deng))風冷式(shi)可控硅(gui)(gui)整(zheng)流氧化電(dian)源(yuan)。在研制過程中主要突破了多方面的技術的問題：
(1)主變(bian)(bian)壓(ya)(ya)器(qi)(qi)形式(shi)：氧化(hua)、電(dian)鍍電(dian)源的(de)(de)(de)關(guan)鍵部分是(shi)(shi)主變(bian)(bian)壓(ya)(ya)器(qi)(qi)，其功率(lv)大、重(zhong)量占整(zheng)臺設備重(zhong)量百分之(zhi)五十以上，也是(shi)(shi)節(jie)能(neng)(neng)的(de)(de)(de)關(guan)鍵。研究(jiu)解決主變(bian)(bian)壓(ya)(ya)器(qi)(qi)結(jie)構形式(shi)是(shi)(shi)設計(ji)的(de)(de)(de)難(nan)點。國外(wai)很(hen)早研究(jiu)節(jie)能(neng)(neng)型、特殊結(jie)構整(zheng)流變(bian)(bian)壓(ya)(ya)器(qi)(qi)，特別是(shi)(shi)日本生產(chan)的(de)(de)(de)大小功率(lv)的(de)(de)(de)表面處理電(dian)源，采用三(san)相五芯柱(zhu)風冷(leng)、節(jie)能(neng)(neng)和特殊結(jie)構的(de)(de)(de)變(bian)(bian)壓(ya)(ya)器(qi)(qi)技術(shu)相當普遍。國內首先突破(po)特殊變(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)(de)理論計(ji)算、采用國產(chan)材料(liao)制造的(de)(de)(de)工藝(yi)控(kong)制，同時改進了(le)(le)繞組方式(shi)，用小并聯(lian)、多繞組有效(xiao)地(di)解決了(le)(le)大電(dian)流氧化(hua)電(dian)源的(de)(de)(de)整(zheng)流元件均流技術(shu)，為全風冷(leng)結(jie)構創造了(le)(le)條件。
(2)整流(liu)形(xing)式(shi)選擇：全風冷(leng)式(shi)結(jie)構(gou)受到大(da)功(gong)率半道(dao)體元件(jian)風冷(leng)散熱器(qi)(qi)極限(xian)的(de)限(xian)制，決定了(le)整流(liu)元件(jian)必須(xu)小(xiao)容量(liang)并(bing)聯。由(you)于國外(wai)半道(dao)體功(gong)率器(qi)(qi)件(jian)的(de)生(sheng)產技術、工藝條件(jian)比國內優越，產品的(de)一致性好，因此采(cai)(cai)用電流(liu)容量(liang)更小(xiao)的(de)螺旋式(shi)二極管(guan)多(duo)個并(bing)聯，均流(liu)系數仍(reng)然很高，國內卻難于采(cai)(cai)用這種形(xing)式(shi)。因此，主變壓(ya)器(qi)(qi)多(duo)繞組均流(liu)和平板型硅元件(jian)安裝專(zhuan)用散熱器(qi)(qi)小(xiao)并(bing)聯技術，成功(gong)地解決了(le)大(da)電流(liu)氧化(hua)電源采(cai)(cai)用全風冷(leng)形(xing)式(shi)的(de)難題。
(3)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)：整流(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)是(shi)(shi)設備(bei)的(de)(de)“靈魂”。控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)的(de)(de)先進性、可靠(kao)性和(he)操(cao)作性直接影響電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)性能(neng)(neng)。國(guo)(guo)內一貫采(cai)用(yong)的(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)結(jie)構(gou)、安裝(zhuang)方(fang)式及控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)性能(neng)(neng)等已(yi)不(bu)適用(yong)于(yu)整流(liu)(liu)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)需(xu)要。為(wei)了(le)(le)迅速(su)提(ti)高(gao)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)的(de)(de)技術(shu)水(shui)(shui)平、減少(shao)重復研究，通過消(xiao)化、吸收和(he)改進進口電(dian)(dian)(dian)源(yuan)(yuan)(yuan)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)性能(neng)(neng)，大(da)(da)(da)(da)大(da)(da)(da)(da)提(ti)高(gao)了(le)(le)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)線(xian)路(lu)(lu)的(de)(de)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)性能(neng)(neng)和(he)可靠(kao)性。集(ji)成電(dian)(dian)(dian)路(lu)(lu)的(de)(de)技術(shu)應(ying)用(yong)，大(da)(da)(da)(da)大(da)(da)(da)(da)簡化了(le)(le)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)線(xian)路(lu)(lu)板的(de)(de)結(jie)構(gou)，整臺(tai)設備(bei)所有控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)功(gong)能(neng)(neng)集(ji)中在(zai)一塊電(dian)(dian)(dian)路(lu)(lu)板上，電(dian)(dian)(dian)路(lu)(lu)板的(de)(de)互換(huan)性好，維修極為(wei)方(fang)便。目前國(guo)(guo)產可控(kong)(kong)(kong)(kong)(kong)(kong)硅整流(liu)(liu)設備(bei)控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)采(cai)用(yong)的(de)(de)幾乎是(shi)(shi)國(guo)(guo)外(大(da)(da)(da)(da)多是(shi)(shi)日本(ben)的(de)(de))八十(shi)年代普遍采(cai)用(yong)的(de)(de)模擬控(kong)(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)電(dian)(dian)(dian)路(lu)(lu)的(de)(de)翻版。大(da)(da)(da)(da)大(da)(da)(da)(da)提(ti)高(gao)了(le)(le)國(guo)(guo)內電(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)(de)整體(ti)(ti)水(shui)(shui)平。
(4)防腐(fu)(fu)(fu)技術：由于主(zhu)變(bian)(bian)(bian)壓(ya)器(qi)為風冷(leng)結(jie)構(gou)(gou)，空氣(qi)中腐(fu)(fu)(fu)蝕性(xing)(xing)氣(qi)體高(gao)速流過主(zhu)變(bian)(bian)(bian)壓(ya)器(qi)時腐(fu)(fu)(fu)蝕性(xing)(xing)加強。采(cai)用(yong)常規變(bian)(bian)(bian)壓(ya)器(qi)難于實現防腐(fu)(fu)(fu)，必須對主(zhu)變(bian)(bian)(bian)壓(ya)器(qi)采(cai)取真空浸漆的特(te)殊(shu)方(fang)式(shi)，即使(shi)有腐(fu)(fu)(fu)蝕性(xing)(xing)介質吸附在變(bian)(bian)(bian)壓(ya)器(qi)表面，也不可能對變(bian)(bian)(bian)壓(ya)器(qi)產(chan)生腐(fu)(fu)(fu)蝕。另外(wai)(wai)，控(kong)制電(dian)路(lu)采(cai)用(yong)密封方(fang)式(shi)，防止了(le)外(wai)(wai)界(jie)空氣(qi)對控(kong)制電(dian)路(lu)腐(fu)(fu)(fu)蝕。結(jie)構(gou)(gou)外(wai)(wai)殼也都采(cai)用(yong)了(le)相應的防腐(fu)(fu)(fu)措施。無論(lun)在變(bian)(bian)(bian)壓(ya)器(qi)絕緣(yuan)防腐(fu)(fu)(fu)，還(huan)是整機控(kong)制線路(lu)及結(jie)構(gou)(gou)上的防腐(fu)(fu)(fu)技術，都有了(le)很大(da)的改變(bian)(bian)(bian)，大(da)大(da)延長了(le)設備使(shi)用(yong)壽(shou)命。
目前(qian)，我國(guo)(guo)(guo)氧化、電鍍整流(liu)電源(yuan)的(de)整體水(shui)平(ping)有(you)(you)了很(hen)大的(de)提(ti)高，廣東繼續走在全國(guo)(guo)(guo)的(de)前(qian)列(lie)，出(chu)(chu)現了眾多有(you)(you)規(gui)模、有(you)(you)實力(li)的(de)專業(ye)電力(li)整流(liu)電源(yuan)生產廠，為中國(guo)(guo)(guo)的(de)表面處理電源(yuan)的(de)技術(shu)進步和(he)國(guo)(guo)(guo)產化作出(chu)(chu)了很(hen)大的(de)貢獻。同(tong)時也(ye)要看到(dao)國(guo)(guo)(guo)產電源(yuan)在工藝相對(dui)穩定情況下與(yu)國(guo)(guo)(guo)外電源(yuan)技術(shu)相比還有(you)(you)一定的(de)差距。需要解決的(de)問題(ti)還很(hen)多，也(ye)是(shi)今后需要發展和(he)提(ti)高的(de)方(fang)面。
(1)大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)整流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)準(zhun)確性(xing)：直流(liu)(liu)(liu)(liu)(liu)(liu)(liu)大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)檢(jian)測精(jing)度是(shi)個(ge)難題，檢(jian)測的(de)(de)手段目(mu)前有很(hen)多(duo)，最為普遍(bian)使用(yong)的(de)(de)是(shi)分流(liu)(liu)(liu)(liu)(liu)(liu)(liu)器(qi)和直流(liu)(liu)(liu)(liu)(liu)(liu)(liu)互感器(qi)，可(ke)以在直流(liu)(liu)(liu)(liu)(liu)(liu)(liu)輸(shu)(shu)(shu)出(chu)母排直接(jie)檢(jian)測電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)值，進(jin)口產品(pin)中(zhong)(zhong)普遍(bian)采(cai)用(yong)。需要(yao)檢(jian)測精(jing)度要(yao)求或在特(te)大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)檢(jian)測，例如電(dian)(dian)(dian)(dian)(dian)解鋁、氯堿電(dian)(dian)(dian)(dian)(dian)解等(deng)行業中(zhong)(zhong)則可(ke)采(cai)用(yong)先進(jin)的(de)(de)霍(huo)爾元件，其精(jing)度可(ke)達到1%。而目(mu)前鋁材氧(yang)化電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)檢(jian)測絕大部分采(cai)用(yong)對(dui)應(ying)方式(shi)(shi)，即(ji)檢(jian)測電(dian)(dian)(dian)(dian)(dian)源(yuan)設備的(de)(de)進(jin)線電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)大小相(xiang)對(dui)應(ying)直流(liu)(liu)(liu)(liu)(liu)(liu)(liu)輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)值大小，該種方式(shi)(shi)影(ying)響因素較多(duo)，例如：電(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)壓(ya)波動，變(bian)壓(ya)器(qi)參數及功率因素的(de)(de)變(bian)化等(deng)，測量裝置穩定性(xing)也較差，都會造(zao)(zao)成輸(shu)(shu)(shu)出(chu)直流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)與(yu)實(shi)際值有較大的(de)(de)誤(wu)差，直接(jie)影(ying)響工(gong)藝員正確計算與(yu)設定而造(zao)(zao)成產品(pin)質(zhi)量不(bu)穩定，也是(shi)造(zao)(zao)成電(dian)(dian)(dian)(dian)(dian)源(yuan)損壞的(de)(de)不(bu)安全因素。
(2)氧化(hua)電(dian)(dian)(dian)(dian)源(yuan)(yuan)保(bao)護(hu)(hu)功(gong)能(neng)：電(dian)(dian)(dian)(dian)工產品的(de)(de)(de)(de)設(she)計(ji)必須注重保(bao)護(hu)(hu)功(gong)能(neng)，特別是(shi)設(she)備(bei)的(de)(de)(de)(de)關鍵(jian)部(bu)分。雖然大電(dian)(dian)(dian)(dian)流(liu)氧化(hua)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)(de)整(zheng)(zheng)流(liu)元件并聯的(de)(de)(de)(de)增加，減少了元件的(de)(de)(de)(de)損壞，但是(shi)整(zheng)(zheng)流(liu)元件的(de)(de)(de)(de)損壞是(shi)不可避(bi)免的(de)(de)(de)(de)，關鍵(jian)要有一(yi)套可靠(kao)的(de)(de)(de)(de)保(bao)護(hu)(hu)措施(shi)。上面(1)中所述：目前國內(nei)(nei)氧化(hua)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)(de)輸出電(dian)(dian)(dian)(dian)流(liu)指(zhi)示和控制電(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)反饋(kui)信號都(dou)來(lai)自三相(xiang)(xiang)進線(xian)電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)取(qu)樣值(zhi)(zhi)，對(dui)應輸出電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)大小，不是(shi)來(lai)自測量輸出電(dian)(dian)(dian)(dian)流(liu)值(zhi)(zhi)。若整(zheng)(zheng)流(liu)元件損壞造成短路(lu)，三相(xiang)(xiang)進線(xian)電(dian)(dian)(dian)(dian)流(liu)值(zhi)(zhi)被設(she)在該處的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)檢測裝置反饋(kui)到控制電(dian)(dian)(dian)(dian)路(lu)，控制電(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)限(xian)(xian)流(liu)功(gong)能(neng)將電(dian)(dian)(dian)(dian)流(liu)限(xian)(xian)制在最大值(zhi)(zhi)，造成電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)(de)空氣開(kai)關(總開(kai)關)因電(dian)(dian)(dian)(dian)流(liu)沒有達到保(bao)護(hu)(hu)極限(xian)(xian)不能(neng)起到斷開(kai)保(bao)護(hu)(hu)作用，結果主變壓器(qi)次級繞組長(chang)時間短路(lu)而損壞。國內(nei)(nei)目前使(shi)用的(de)(de)(de)(de)大部(bu)分電(dian)(dian)(dian)(dian)源(yuan)(yuan)都(dou)有這種潛在的(de)(de)(de)(de)缺點。其它保(bao)護(hu)(hu)功(gong)能(neng)的(de)(de)(de)(de)有效性(例如：過(guo)熱、缺相(xiang)(xiang)、過(guo)流(liu)等(deng))、特別是(shi)某些傳(chuan)感器(qi)的(de)(de)(de)(de)可靠(kao)性有待提高。
(3)電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)(ya)：電(dian)(dian)源(yuan)設(she)備(bei)電(dian)(dian)壓(ya)(ya)的高低(di)對表面的處理(li)質量影響不大，與電(dian)(dian)流密(mi)度有(you)密(mi)切關系(xi)。電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)(ya)不宜(yi)設(she)計過(guo)高(脈(mo)沖電(dian)(dian)源(yuan)除外)。否則，電(dian)(dian)源(yuan)設(she)備(bei)產生諧波，嚴重干(gan)擾(rao)電(dian)(dian)網的波形、破壞補償電(dian)(dian)容器(qi)，給(gei)用(yong)戶(hu)和(he)供電(dian)(dian)部門造成了(le)損失。
(4)電(dian)(dian)(dian)源(yuan)技術進(jin)步：我國(guo)(guo)表面(mian)(mian)處理電(dian)(dian)(dian)源(yuan)從仿制(zhi)到成(cheng)熟已有十多年了(le)，技術水平(ping)基本保(bao)持原來水平(ping)。國(guo)(guo)外已經(jing)發展(zhan)了(le)性能可(ke)靠，自(zi)(zi)動(dong)化水平(ping)高的智能化電(dian)(dian)(dian)源(yuan)。例如，當鋁材工(gong)件進(jin)入氧化槽后，只需(xu)輸入需(xu)要(yao)氧化膜厚度，檢測系統根據槽液溫(wen)度、槽液中(zhong)內阻等，自(zi)(zi)動(dong)顯示(shi)出(chu)工(gong)件的實際(ji)面(mian)(mian)積(ji)和需(xu)要(yao)氧化的。
