一電力控制器
SCR電力控制器的基本原理是通過(guò)控制信號(hào)輸入,去控制串在主回路中的SCR(晶閘管)模塊,改變主回路中電壓的導(dǎo)通與關(guān)斷,由此達(dá)到調(diào)節(jié)電壓或功率的目的。控制器一般是由控制板加上主機(jī)(主回路)組成。 SCR電力控制器又可分為調(diào)壓器和調(diào)功器。 采用相位控制模式的SCR電力控制器可叫做調(diào)壓器,它可以方便地調(diào)節(jié)電壓值,可用于電爐溫度控制,燈光調(diào)節(jié),異步電動(dòng)機(jī)降壓軟啟動(dòng)和調(diào)壓調(diào)速等,也可用做調(diào)節(jié)變壓器一次側(cè)電壓,代替效率低下的調(diào)壓變壓器。

德國(guó)AEG電源系統(tǒng)公司電源調(diào)功器

 

德國(guó)AEG電源調(diào)功器產(chǎn)品的主要特點(diǎn)
1:耐反擊穿電壓高。
2:具有總線通訊功能。其他產(chǎn)品不一定帶。
3:具有自診斷功能,可以實(shí)現(xiàn)診斷信息上傳到計(jì)算機(jī),進(jìn)行維護(hù)提示。其他產(chǎn)品沒(méi)有此功能。
4:當(dāng)控制系統(tǒng)故障時(shí),可以通過(guò)盤(pán)柜上的手動(dòng)按鈕和液晶顯示器進(jìn)行手動(dòng)控制。在不停機(jī)的情況下,實(shí)現(xiàn)功率的精確控制,其他產(chǎn)品必須外配儀表進(jìn)行操作,增加了成本且不安全.
5在總線卡故障時(shí),AEG的總線卡自動(dòng)保留故障前的一個(gè)設(shè)定值作為默認(rèn)值,生產(chǎn)的正常運(yùn)行! 而其他產(chǎn)品要么沒(méi)有總線卡,要么總線卡不能保留一個(gè)設(shè)定值作為默認(rèn)值,造成生產(chǎn)難以繼續(xù)正常進(jìn)行。
6. 精度非常高,達(dá)到0.5%、1%、3%。
7:性非常高,不但用于阻性負(fù)載,也可用于變壓器負(fù)載,其他產(chǎn)品難以用于變壓器負(fù)載。在洛陽(yáng)浮法玻璃集團(tuán)公司的浮法一線、二線使用的AEG調(diào)功器已經(jīng)十年了,現(xiàn)在仍然正常運(yùn)行。且洛玻集團(tuán)公司的浮法玻璃生產(chǎn)線的調(diào)功器負(fù)載為感性負(fù)載(變壓器),更難以控制和精度.可是AEG調(diào)功器卻滿足了這些要求,十年來(lái)連續(xù)保障了生產(chǎn)正常.
8. 在風(fēng)冷狀態(tài)下,電流可以高達(dá)2900A,超過(guò)3000A 用水冷.其他產(chǎn)品大多在600 A以下風(fēng)冷,超過(guò)600A用水冷,給設(shè)備帶來(lái)極大的安全隱患.
9. 同等功率下,體積最小,功能最強(qiáng).
10.自帶電流、電壓測(cè)量裝置,能夠?qū)⒇?fù)載的電流、電壓和功率值傳給上位機(jī),自帶報(bào)的供電電源24VDC。
11. 五年以上的國(guó)內(nèi)眾多用戶中,目前沒(méi)有發(fā)現(xiàn)一例調(diào)功器可控硅被擊穿的事情,最多是保險(xiǎn)絲被燒壞.
12. 使用專業(yè)的Thyro組態(tài)調(diào)試軟件—Thyro-Tool Family進(jìn)行組態(tài)測(cè)試,并可以保存每個(gè)調(diào)功器的組態(tài)測(cè)試參數(shù),以便優(yōu)化.
13. 內(nèi)置快熔保險(xiǎn)絲,回路檢測(cè).真正實(shí)現(xiàn)了調(diào)功的一體化,包括快熔,可控硅,觸發(fā)電路板,保護(hù)電路, 電流電壓功率檢測(cè),散熱器,通訊,自診斷,控制板等功能.
14:具有50多年專業(yè)經(jīng)驗(yàn)的高品質(zhì)。 AEG公司已經(jīng)為法國(guó)空中客車公司,德國(guó)奔馳汽車公司,德國(guó)寶馬汽車公司,德國(guó)瓦克公司(多晶硅),拜耳公司,巴斯夫公司,易普森電爐公司,洛玻公司,南玻公司,英國(guó)Pilkington上海玻璃公司(常州),等世界公司提供產(chǎn)品和服務(wù)。

    過(guò)流保護(hù):一般地說(shuō),過(guò)流保護(hù)不能避免負(fù)載短路造成的設(shè)備損壞,不能代替快速熔斷器。     負(fù)載短路保護(hù):用戶需外配快速熔斷器作為短路保護(hù),一般按額定負(fù)載電流的1.5 倍選擇。三. 裝箱清單表 GBC2M-3 整機(jī)一臺(tái), 10K 電位器(含刻度盤(pán))兩套, 說(shuō)明書(shū)1 份四.選型單五.訂貨說(shuō)明: 1.電力調(diào)整器電流容量選擇參考    一般純阻負(fù)載:所選電力調(diào)整器的電流容量應(yīng)大于負(fù)載最大電流。    硅碳棒負(fù)載:當(dāng)取消變壓器時(shí),硅碳棒應(yīng)串聯(lián),使之能夠承受電源電壓的70%~80%以上。硅碳棒在700~800 ℃存在負(fù)阻區(qū),所選電力調(diào)整器的電流容量應(yīng)大于負(fù)載電流1.7 倍以上。   電熱管負(fù)載:易受潮、局部短路等,所選電力調(diào)整器的電流容量應(yīng)大于負(fù)載電流1.7 倍以上。   變壓器負(fù)載:應(yīng)帶電流限制功能,所選電力調(diào)整器的電流容量應(yīng)大于負(fù)載電流2~2.5 倍以上。 2. 定貨例:GBC2M-3-4T-080-N-U00 含義解釋:4~20mA 控制信號(hào)輸入,電流容量80A(純阻負(fù)載最大電流80A;硅碳棒負(fù)載、電熱管負(fù)載最大電流48A;變壓器負(fù)載最大電流32A)。六.安裝尺寸圖和電器原理圖框圖(參考尺寸) 不應(yīng)出現(xiàn)突跳、抖動(dòng)或變化趨勢(shì)與輸入信號(hào)不成線性關(guān)系等現(xiàn)象?砂醋詈(jiǎn)接線圖(見(jiàn)下圖)接線,進(jìn)行自動(dòng)或手動(dòng)調(diào)試。負(fù)載電源應(yīng)與調(diào)壓器控制板電源筒相位。 27.  自動(dòng)調(diào)試: 將儀表4~20mA 的輸出信號(hào)接到C1、C2 端,R1、R2 短路,按上圖的自動(dòng)控制接線。輸入變化信號(hào)逐步增大時(shí),綠色輸入燈亮度和負(fù)載電壓應(yīng)隨輸入增加。 28.  手動(dòng)調(diào)整:外接10KΩ手動(dòng)電位器。電位器的兩個(gè)固定端分別接V0、GND 端,滑動(dòng)端接R2 端,按上圖的手動(dòng)控制接線。調(diào)整手動(dòng)電位器,負(fù)載電壓調(diào)整范圍為0~100%。此時(shí),負(fù)載電壓應(yīng)均勻變化。 29.  上電緩起動(dòng)時(shí)間:調(diào)整控制板內(nèi)的P3 電位器,啟動(dòng)時(shí)間0.2~120 秒用戶可設(shè)。注:空載調(diào)試所測(cè)得的輸出電壓無(wú)效。八. 接實(shí)際負(fù)載調(diào)試假負(fù)載調(diào)試通過(guò)后,再接實(shí)際負(fù)載調(diào)試。對(duì)于變壓器負(fù)載,變壓器的二次側(cè)不能空載開(kāi)路,必須加實(shí)際負(fù)載。加電前,需檢查負(fù)載絕緣強(qiáng)度,有無(wú)短路、接觸不良等現(xiàn)象。檢查調(diào)壓器安裝位置是否合適,機(jī)柜通風(fēng)是否良好等?刂瓢咫娫措妷簯(yīng)與負(fù)載電壓同相位,電壓應(yīng)符合要求。逐步增加控制輸入信號(hào)或調(diào)整手動(dòng)電位器,使負(fù)載電壓從小到大逐步增加。若發(fā)現(xiàn)異常,需停機(jī)檢查。負(fù)載的最大電壓取決于新電爐的烘爐情況,負(fù)載特性,爐溫高低,負(fù)載電流大小等情況。變壓器負(fù)載若發(fā)生磁飽和時(shí),負(fù)載最大電壓也受限制。九.控制板常見(jiàn)接線組合下圖列出了常見(jiàn)的接線組合,供設(shè)計(jì)時(shí)參考。十.電流限制(選件)參照接線組合圖(上圖)的組合方式4 或6,接實(shí)際負(fù)載調(diào)試: 30. 先將限流電位器調(diào)至不限流位置,R3 與GND 間電壓約為5V。 31. 手動(dòng)給定負(fù)載電流值后,調(diào)限流電位器直到負(fù)載電流值剛開(kāi)始下降,電流限制即調(diào)好。 32. 調(diào)功方式時(shí),最大電流限制功能被取消。十一. 過(guò)流報(bào)警(選件)參照接線組合圖(上圖),接實(shí)際負(fù)載調(diào)試:   DIP 功能開(kāi)關(guān)SW1-1 的設(shè)置8 SW1-1:ON,過(guò)流報(bào)警方式 SW1-1: OFF,標(biāo)定過(guò)流報(bào)警值 n             過(guò)流報(bào)警值的標(biāo)定方法一般,選取過(guò)流報(bào)警值為最大負(fù)載電流的1.3 倍。按過(guò)流報(bào)警值的1/2 進(jìn)行標(biāo)定。 1. 設(shè)SW1-1 為OFF。 2. 手動(dòng)調(diào)節(jié)負(fù)載電流,達(dá)到過(guò)流報(bào)警值的1/2。 3. 調(diào)整控制板內(nèi)P2 電位器,使?fàn)顟B(tài)燈由綠變成黃色,標(biāo)定完成。例如:若最大負(fù)載電流為100A,過(guò)流報(bào)警值選130A,而按過(guò)流報(bào)警值的1/2 即:65A 標(biāo)定。 n             過(guò)流報(bào)警 1. 設(shè)SW1-1 為ON 2. 運(yùn)行中,負(fù)載電流大于過(guò)流報(bào)警值時(shí),過(guò)流報(bào)警動(dòng)作:調(diào)節(jié)輸出急停、報(bào)警輸出接點(diǎn)吸合、狀態(tài)指示燈為紅色。例如:若最大負(fù)載電流為100A,過(guò)流報(bào)警值選130A,按65A 標(biāo)定。SW1-1 為ON,運(yùn)行過(guò)程中,負(fù)載電流大于130A 時(shí),過(guò)流報(bào)警動(dòng)作。 n             調(diào)功方式時(shí)過(guò)流報(bào)警值的標(biāo)定調(diào)功方式的過(guò)流報(bào)警值必須在調(diào)壓方式下進(jìn)行標(biāo)定。標(biāo)定后,再轉(zhuǎn)到調(diào)功方式。 n        過(guò)流報(bào)警的復(fù)位過(guò)流報(bào)警保護(hù)時(shí),狀態(tài)燈變成紅色,繼電器動(dòng)作吸合、輸出停止。需檢查過(guò)流原因排除故障后再啟動(dòng)。復(fù)位方法:1)斷電后重新上電運(yùn)行或2)閉合起停開(kāi)關(guān),置待機(jī)狀態(tài),黃燈閃爍;斷開(kāi)起停開(kāi)關(guān),系統(tǒng)運(yùn)行,綠燈亮。 n        注意事項(xiàng)由于實(shí)際負(fù)載冷熱阻變化、負(fù)載老化、變壓器負(fù)載、上電浪涌電流、瞬間電流異常等因素,過(guò)流保護(hù)動(dòng)作靈敏度過(guò)高容易造成誤動(dòng)作。進(jìn)一步可微調(diào)P2,反時(shí)針調(diào)整靈敏度高,動(dòng)作提前;順時(shí)針調(diào)整靈敏度低,旋到極限位置時(shí)(或置SW1-1 為OFF 時(shí))保護(hù)被取消。因?yàn)檫^(guò)流保護(hù)并不能取代快速熔斷器的作用,所以用戶應(yīng)自行外配快速熔斷器,容量應(yīng)為負(fù)載最大電流的1.5 倍左右。注:電流限制、過(guò)流報(bào)警選件均是通過(guò)選件“C”一個(gè)選件實(shí)現(xiàn),過(guò)零調(diào)功時(shí)無(wú)電流限制功能。十二.調(diào)試中的問(wèn)題及故障排除當(dāng)用戶系統(tǒng)出現(xiàn)故障時(shí),首應(yīng)判斷故障的部位,應(yīng)將儀表、調(diào)壓器和負(fù)載的問(wèn)題分開(kāi)處理。 n             負(fù)載無(wú)輸出 1. 檢查電源:控制板、負(fù)載電源是否正常,快熔是否燒斷。 2. 檢查負(fù)載:負(fù)載是否開(kāi)路或接線有問(wèn)題。 3. 檢查控制板狀態(tài)燈:綠色,運(yùn)行狀態(tài);黃色閃爍,待機(jī)狀態(tài)(無(wú)輸出);紅色,過(guò)流報(bào)警(無(wú)輸出);紅、黃閃爍,散熱器超溫報(bào)警(無(wú)輸出);黃色常亮,控制板故障;不亮,控制板未供電或有故障。 4. 檢查控制板輸入指示燈:綠色,亮度應(yīng)隨輸入信號(hào)變化。 5. 檢查控制板P1 電位器的位置:順時(shí)針調(diào)整,輸出電壓增加。 6. 檢查控制板R1、R2 短路片:自動(dòng)控制時(shí),R1、R2 短路片應(yīng)接好。 7. 檢查輸入信號(hào):范圍,4~20mA。輸入信號(hào)> 5.6mA, 極性是否接反。 8. 檢查控制板R2 端:R2 輸出0~5V(隨輸入信號(hào)4~20mA 變化)。 9. 檢查控制板RS 端:RS、GND 端短路,待機(jī)狀態(tài)(無(wú)輸出),狀態(tài)燈黃色閃爍。 10. 檢查電流限制電位器:是否限流值調(diào)得太低。 n       負(fù)載電壓不正常 1. 檢查電源:控制板、負(fù)載電源是否正常?刂瓢咫娫磻(yīng)與負(fù)載電源同相位。 2. 檢查負(fù)載:是否空載、輕載運(yùn)行。變壓器負(fù)載:二次側(cè)不能空載,必須帶全載。 3. 手動(dòng)檢查:若手動(dòng)控制正常,初步判斷調(diào)壓器沒(méi)有問(wèn)題。否則,接假負(fù)載繼續(xù)檢查。 4. 自動(dòng)檢查:控制輸入變化4~20mA 時(shí),R2 端的電壓變化范圍應(yīng)為0~5V。 5. 輸出電壓只能調(diào)到負(fù)載電源的一半:調(diào)壓器的晶閘管模塊損壞一半。 6、負(fù)載電壓為最大不受控輸出始終為最大,無(wú)論是手動(dòng)還是自動(dòng)都不可調(diào),可能原因: 1. 可能負(fù)載開(kāi)路或未接負(fù)載 2. 調(diào)壓器的晶閘管模塊擊穿損壞。晶閘管模塊輸出端的電阻一般大于500KΩ。         開(kāi)始運(yùn)行正常,一段時(shí)間后,輸出始終為最大。無(wú)論是手動(dòng)還是自動(dòng)都不可調(diào)。關(guān)機(jī)后、再開(kāi)機(jī),又可正常運(yùn)行?赡茉颍 1. 環(huán)境溫度過(guò)高。 2. 負(fù)載過(guò)流。負(fù)載瞬時(shí)過(guò)流造成晶閘管模塊熱擊穿。 n       接假負(fù)載按最簡(jiǎn)接線調(diào)試若故障部位不易判斷,可采用假負(fù)載調(diào)試法,假負(fù)載一般為100~200W 的燈泡。 1. 手動(dòng)調(diào)節(jié)正常:初步判斷調(diào)壓器正常,懷疑負(fù)載有問(wèn)題。需檢查負(fù)載電源電壓、保險(xiǎn)絲和接觸不良、斷線、短路、絕緣下降、放電打火等問(wèn)題。 2. 手動(dòng)調(diào)節(jié)正常,自動(dòng)不正常:若控制輸入4~20mA 電流不正常,需進(jìn)一步檢查儀表;否則,需檢查 P1 電位器是否將電壓限幅調(diào)得太低,R1、R2 短路片是否接好。 3. 手動(dòng)、自動(dòng)調(diào)節(jié)都正常:判斷調(diào)壓器沒(méi)有問(wèn)題。十三.加熱器特性十四. 不同負(fù)載的控制策略 1. 變壓器控制:a)變壓器的設(shè)計(jì)容量不足,造成當(dāng)電流增加到一定程度時(shí)變壓器鐵芯飽合,導(dǎo)致電流劇增、波形畸變、損壞器件。需重新設(shè)計(jì)變壓器,或加負(fù)載最大電流限制功能。b)運(yùn)行過(guò)程瞬間斷電后又上電等,造成上電時(shí)的磁通極性與剩磁極性(固有剩磁和瞬間斷電正在衰減的磁場(chǎng))的“撞車”,產(chǎn)生危害性沖擊電壓、電流。所以電感負(fù)載尤其是變壓器,應(yīng)采用上電緩起動(dòng),逐步順磁和緩關(guān)斷逐步衰減磁場(chǎng)。c) 變壓器為感性負(fù)載,窄脈沖觸發(fā)不。脈寬可變直流觸發(fā)技術(shù),能提供負(fù)載電流到達(dá)晶閘管擎駐電流的足夠時(shí)間,確保觸發(fā)。注:變壓器負(fù)載不能空載調(diào)試、運(yùn)行。 2. 純金屬類:硅鉬、鉬絲、鎢、白金、石墨等負(fù)載冷態(tài)電阻小,低、中溫段需限壓和限流;隨著溫度增高,電阻按線性增大,在高溫段反而需增加負(fù)載電壓。RK16P 調(diào)壓器的電流限制功能,是專門(mén)為這類負(fù)載設(shè)計(jì)的。此外,帶有多組PID 和調(diào)節(jié)輸出限幅的儀表,也可控制負(fù)載電流。例如:島電的FP21、SR253、FP93 等可設(shè)計(jì)低、中、高溫區(qū)的調(diào)節(jié)輸出限制。 3. 硅碳棒: 一般采用緩起動(dòng)> 1 分鐘或更長(zhǎng)和電流限制,避開(kāi)在700℃附近負(fù)阻的沖擊電流(新棒更明顯)。 4. 恒阻(泛指冷熱阻變化小的負(fù)載):控制策略較簡(jiǎn)單,可采用過(guò)零調(diào)功方式,克服調(diào)壓方式功率因數(shù)低、污染電網(wǎng)的缺點(diǎn)。周期過(guò)零(占空比控制),一般采用大功率SSR 實(shí)現(xiàn)。周波過(guò)零調(diào)功,負(fù)載電流以全正弦波為單位均勻分布,多臺(tái)設(shè)備運(yùn)行時(shí),總動(dòng)力電流相對(duì)均衡(避免了周期過(guò)零方式電流集中),改善爐溫均勻性,避免了電流表撞針,重要的是:提高了電源利用率和避免電力設(shè)備增容,節(jié)電效果十分明顯。RK16P 是調(diào)功調(diào)壓一體化設(shè)計(jì),既可調(diào)壓也能調(diào)功(周期和周波過(guò)零兩種方式),可滿足不同的控制策略。十五.GBC2M-3 控制器的基本特性圖示: 十六.調(diào)功、調(diào)壓一體化技術(shù)(選件) 調(diào)壓方式具有負(fù)載電流沖擊小、適合變壓器控制等特點(diǎn),但不可避免產(chǎn)生電源污染和降低電網(wǎng)功率因數(shù)。過(guò)零調(diào)功方式避免了調(diào)壓方式的不足,但無(wú)法限制電流,負(fù)載沖擊電流較大,GBC2M-3的調(diào)功調(diào)壓功能提供了兩者優(yōu)點(diǎn)的結(jié)合,可根據(jù)負(fù)載情況方便地切換這兩種工作方式。 USER(U1)外部開(kāi)關(guān)設(shè)置:開(kāi)路時(shí),為調(diào)功;短路時(shí),為調(diào)壓。

Passing high currents through the glass produces direct heating in the resistance presented by the glass, named boosting. This heating is beneficial as it heats the&lsquo;colder&rsquo; bottom glass in the furnace. This heated bottom glass rises towards the tophas a stirring effect which helps with melting, heat transfertemperature homogenisation. Boosting is often used to meet periodic fluctuations in production demand or to support the pull rate of a furnace at the end of its operating life. Boosting may also help to reduce NOx emissions. In this application the EPower Controller is controlling the power injected by the electrodes in the molten glass while controlling the true power or the current (the power injected is self compensated by the glass temperature) Controlled convection currents to promote homogeneity Accurate true power or electrodes current control Digital communication allowing process parameters to be monitored by a supervisor: current, voltage, poweralarms Electrodes Molten glass Three phase power supply T2550 Input/output control Eycon&trade; Visual Supervisor Vacuum furnace control Energy control Efficiency optimization EPower Controller Control Modularity Energy information Several switching modes iTools software configuration Digital communications Vacuum device Digital communication COMPOSITE MATERIAL In composite material production polymerisation is made in an autoclave at very high temperature.

Ageing compensation of the silicon carbide heaters with power control Power distribution control in the heater elements providing cost savings: suppression of inrush current for a better energy managementa minimum stress on the power transformers Digital communication with standard protocols for an efficient process monitoring Use Predictive Load Management across the glass plant to reduce energy costs www.eurotherm.com/ E Power SEMICONDUCTOR MANUFACTURING Silicon was discovered in 1823 and is used in the manufacture of today''s semiconductors. Semiconductors need a silicon of a very high purity and, therefore, the silicon is transformed by successive stages (crystal growing, epitaxy) that need very slowaccurate heating. The EPower Controller will provide many solutions to this specific and expensive process: Precisesteady control of the heater elements Advancedconfigurable strategy enables the EPower Controller to adapt to the load state Secure your process utilising a comprehensive alarm strategyby transferring process information to a supervisor CONTINUOUS ANNEALING FURNACE After castingmilling, metals are passed through an annealing furnace in order to increase ductilityreduce brittleness. In the case of a continuous metal sheet, this is a multi-zone furnace consuming several Megawatts of power. Each zone consists of one or multiple thermocouples feeding the process variable (PV) into a temperature controller, Programmable Automation Controller (T2550 PAC) or PLC. The control device then calculates the required power input to meet the process set point (SP),sends this to the Power Controller via digital comms or via an analogue signal. The Power Controller then fires the element, either directly or via a transformer depending on the element specifications. Two-leg, true three phase control or 4 x single phase control available Load Sequencing - integral firing sequence control optimises instantaneous energy consumption across all zones Load Shedding - Predictive Load Management peak energy demand algorithm enables power smoothing to reduce peak demand Communication of PV, SPprocess data Remote configuration via comms or user interface TIN BATH FURNACE IN FLOAT MANUFACTURING Three phase power supply Multizone control Molten glass Multizone heating Roof heating with silicon carbide elements Supervisor Slave Master Network Multiple Slaves (1 per Zone) Zone 1 Zone n Continuous Annealing Furnace Transformer Transformer Molten tin PLM PLM PLM Predictive Load Management PLM PLM PLM Predictive Load Management With EPower Controllers you are not only buying one of the best power controllers in the world, you are supported by a global network of application and control specialists from Eurotherm.
