      一電力控制器
      SCR電力控制器的基本原理是通過控制信號輸入,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通與關(guān)斷,由此達到調(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(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),異步電動機降壓軟啟動和調(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AEG電源系統(tǒng)公司電源調(diào)功器

       

      德國AEG電源調(diào)功器產(chǎn)品的主要特點
      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,可以實現(xiàn)診斷信息上傳到計算機,進行維護提示。其他產(chǎn)品沒有此功能。
      4:當控制系統(tǒng)故障時,可以通過盤柜上的手動按鈕和液晶顯示器進行手動控制。在不停機的情況下,實現(xiàn)功率的精確控制,其他產(chǎn)品必須外配儀表進行操作,增加了成本且不安全.
      5在總線卡故障時,AEG的總線卡自動保留故障前的一個設(shè)定值作為默認值,生產(chǎn)的正常運行! 而其他產(chǎn)品要么沒有總線卡,要么總線卡不能保留一個設(shè)定值作為默認值,造成生產(chǎn)難以繼續(xù)正常進行。
      6. 精度非常高,達到0.5%、1%、3%。
      7:性非常高,不但用于阻性負載,也可用于變壓器負載,其他產(chǎn)品難以用于變壓器負載。在洛陽浮法玻璃集團公司的浮法一線、二線使用的AEG調(diào)功器已經(jīng)十年了,現(xiàn)在仍然正常運行。且洛玻集團公司的浮法玻璃生產(chǎn)線的調(diào)功器負載為感性負載(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,十年來連續(xù)保障了生產(chǎn)正常.
      8. 在風冷狀態(tài)下,電流可以高達2900A,超過3000A 用水冷.其他產(chǎn)品大多在600 A以下風冷,超過600A用水冷,給設(shè)備帶來極大的安全隱患.
      9. 同等功率下,體積最小,功能最強.
      10.自帶電流、電壓測量裝置,能夠?qū)⒇撦d的電流、電壓和功率值傳給上位機,自帶報的供電電源24VDC。
      11. 五年以上的國內(nèi)眾多用戶中,目前沒有發(fā)現(xiàn)一例調(diào)功器可控硅被擊穿的事情,最多是保險絲被燒壞.
      12. 使用專業(yè)的Thyro組態(tài)調(diào)試軟件—Thyro-Tool Family進行組態(tài)測試,并可以保存每個調(diào)功器的組態(tài)測試參數(shù),以便優(yōu)化.
      13. 內(nèi)置快熔保險絲,回路檢測.真正實現(xiàn)了調(diào)功的一體化,包括快熔,可控硅,觸發(fā)電路板,保護電路, 電流電壓功率檢測,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)驗的高品質(zhì)。 AEG公司已經(jīng)為法國空中客車公司,德國奔馳汽車公司,德國寶馬汽車公司,德國瓦克公司(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Pilkington上海玻璃公司(常州),等世界公司提供產(chǎn)品和服務(wù)。

27.  自動調(diào)試: 將儀表4~20mA 的輸出信號接到C1、C2 端,R1、R2 短路,按上圖的自動控制接線。輸入變化信號逐步增大時,綠色輸入燈亮度和負載電壓應(yīng)隨輸入增加。 28.  手動調(diào)整:外接10KΩ手動電位器。電位器的兩個固定端分別接V0、GND 端,滑動端接R2 端,按上圖的手動控制接線。調(diào)整手動電位器,負載電壓調(diào)整范圍為0~100%。此時,負載電壓應(yīng)均勻變化。 29.  上電緩起動時間:調(diào)整控制板內(nèi)的P3 電位器,啟動時間0.2~120 秒用戶可設(shè)。注:空載調(diào)試所測得的輸出電壓無效。八. 接實際負載調(diào)試假負載調(diào)試通過后,再接實際負載調(diào)試。對于變壓器負載,變壓器的二次側(cè)不能空載開路,必須加實際負載。加電前,需檢查負載絕緣強度,有無短路、接觸不良等現(xiàn)象。檢查調(diào)壓器安裝位置是否合適,機柜通風是否良好等。控制板電源電壓應(yīng)與負載電壓同相位,電壓應(yīng)符合要求。逐步增加控制輸入信號或調(diào)整手動電位器,使負載電壓從小到大逐步增加。若發(fā)現(xiàn)異常,需停機檢查。負載的最大電壓取決于新電爐的烘爐情況,負載特性,爐溫高低,負載電流大小等情況。變壓器負載若發(fā)生磁飽和時,負載最大電壓也受限制。九.控制板常見接線組合下圖列出了常見的接線組合,供設(shè)計時參考。十.電流限制(選件)參照接線組合圖(上圖)的組合方式4 或6,接實際負載調(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. 手動給定負載電流值后,調(diào)限流電位器直到負載電流值剛開始下降,電流限制即調(diào)好。 32. 調(diào)功方式時,最大電流限制功能被取消。十一. 過流報警(選件)參照接線組合圖(上圖),接實際負載調(diào)試:   DIP 功能開關(guān)SW1-1 的設(shè)置8 SW1-1:ON,過流報警方式 SW1-1: OFF,標定過流報警值 n             過流報警值的標定方法一般,選取過流報警值為最大負載電流的1.3 倍。按過流報警值的1/2 進行標定。 1. 設(shè)SW1-1 為OFF。 2. 手動調(diào)節(jié)負載電流,達到過流報警值的1/2。 3. 調(diào)整控制板內(nèi)P2 電位器,使狀態(tài)燈由綠變成黃色,標定完成。例如:若最大負載電流為100A,過流報警值選130A,而按過流報警值的1/2 即:65A 標定。 n             過流報警 1. 設(shè)SW1-1 為ON 2. 運行中,負載電流大于過流報警值時,過流報警動作:調(diào)節(jié)輸出急停、報警輸出接點吸合、狀態(tài)指示燈為紅色。例如:若最大負載電流為100A,過流報警值選130A,按65A 標定。SW1-1 為ON,運行過程中,負載電流大于130A 時,過流報警動作。 n             調(diào)功方式時過流報警值的標定調(diào)功方式的過流報警值必須在調(diào)壓方式下進行標定。標定后,再轉(zhuǎn)到調(diào)功方式。 n        過流報警的復位過流報警保護時,狀態(tài)燈變成紅色,繼電器動作吸合、輸出停止。需檢查過流原因排除故障后再啟動。復位方法:1)斷電后重新上電運行或2)閉合起停開關(guān),置待機狀態(tài),黃燈閃爍;斷開起停開關(guān),系統(tǒng)運行,綠燈亮。 n        注意事項由于實際負載冷熱阻變化、負載老化、變壓器負載、上電浪涌電流、瞬間電流異常等因素,過流保護動作靈敏度過高容易造成誤動作。進一步可微調(diào)P2,反時針調(diào)整靈敏度高,動作提前;順時針調(diào)整靈敏度低,旋到極限位置時(或置SW1-1 為OFF 時)保護被取消。因為過流保護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)為負載最大電流的1.5 倍左右。注:電流限制、過流報警選件均是通過選件“C”一個選件實現(xiàn),過零調(diào)功時無電流限制功能。十二.調(diào)試中的問題及故障排除當用戶系統(tǒng)出現(xiàn)故障時,首應(yīng)判斷故障的部位,應(yīng)將儀表、調(diào)壓器和負載的問題分開處理。 n             負載無輸出 1. 檢查電源:控制板、負載電源是否正常,快熔是否燒斷。 2. 檢查負載:負載是否開路或接線有問題。 3. 檢查控制板狀態(tài)燈:綠色,運行狀態(tài);黃色閃爍,待機狀態(tài)(無輸出);紅色,過流報警(無輸出);紅、黃閃爍,散熱器超溫報警(無輸出);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)隨輸入信號變化。 5. 檢查控制板P1 電位器的位置:順時針調(diào)整,輸出電壓增加。 6. 檢查控制板R1、R2 短路片:自動控制時,R1、R2 短路片應(yīng)接好。 7. 檢查輸入信號:范圍,4~20mA。輸入信號> 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4~20mA 變化)。 9. 檢查控制板RS 端:RS、GND 端短路,待機狀態(tài)(無輸出),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       負載電壓不正常 1. 檢查電源:控制板、負載電源是否正常?刂瓢咫娫磻(yīng)與負載電源同相位。 2. 檢查負載:是否空載、輕載運行。變壓器負載:二次側(cè)不能空載,必須帶全載。 3. 手動檢查:若手動控制正常,初步判斷調(diào)壓器沒有問題。否則,接假負載繼續(xù)檢查。 4. 自動檢查:控制輸入變化4~20mA 時,R2 端的電壓變化范圍應(yīng)為0~5V。 5. 輸出電壓只能調(diào)到負載電源的一半:調(diào)壓器的晶閘管模塊損壞一半。 6、負載電壓為最大不受控輸出始終為最大,無論是手動還是自動都不可調(diào),可能原因: 1. 可能負載開路或未接負載 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。         開始運行正常,一段時間后,輸出始終為最大。無論是手動還是自動都不可調(diào)。關(guān)機后、再開機,又可正常運行?赡茉颍 1. 環(huán)境溫度過高。 2. 負載過流。負載瞬時過流造成晶閘管模塊熱擊穿。 n       接假負載按最簡接線調(diào)試若故障部位不易判斷,可采用假負載調(diào)試法,假負載一般為100~200W 的燈泡。 1. 手動調(diào)節(jié)正常:初步判斷調(diào)壓器正常,懷疑負載有問題。需檢查負載電源電壓、保險絲和接觸不良、斷線、短路、絕緣下降、放電打火等問題。 2. 手動調(diào)節(jié)正常,自動不正常:若控制輸入4~20mA 電流不正常,需進一步檢查儀表;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、自動調(diào)節(jié)都正常:判斷調(diào)壓器沒有問題。十三.加熱器特性十四. 不同負載的控制策略 1. 變壓器控制:a)變壓器的設(shè)計容量不足,造成當電流增加到一定程度時變壓器鐵芯飽合,導致電流劇增、波形畸變、損壞器件。需重新設(shè)計變壓器,或加負載最大電流限制功能。b)運行過程瞬間斷電后又上電等,造成上電時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)的“撞車”,產(chǎn)生危害性沖擊電壓、電流。所以電感負載尤其是變壓器,應(yīng)采用上電緩起動,逐步順磁和緩關(guān)斷逐步衰減磁場。c) 變壓器為感性負載,窄脈沖觸發(fā)不。脈寬可變直流觸發(fā)技術(shù),能提供負載電流到達晶閘管擎駐電流的足夠時間,確保觸發(fā)。注:變壓器負載不能空載調(diào)試、運行。 2. 純金屬類:硅鉬、鉬絲、鎢、白金、石墨等負載冷態(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載電壓。RK16P 調(diào)壓器的電流限制功能,是專門為這類負載設(shè)計的。此外,帶有多組PID 和調(diào)節(jié)輸出限幅的儀表,也可控制負載電流。例如:島電的FP21、SR253、FP93 等可設(shè)計低、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> 1 分鐘或更長和電流限制,避開在700℃附近負阻的沖擊電流(新棒更明顯)。 4. 恒阻(泛指冷熱阻變化小的負載):控制策略較簡單,可采用過零調(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。周期過零(占空比控制),一般采用大功率SSR 實現(xiàn)。周波過零調(diào)功,負載電流以全正弦波為單位均勻分布,多臺設(shè)備運行時,總動力電流相對均衡(避免了周期過零方式電流集中),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,既可調(diào)壓也能調(diào)功(周期和周波過零兩種方式),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)壓方式具有負載電流沖擊小、適合變壓器控制等特點,但不可避免產(chǎn)生電源污染和降低電網(wǎng)功率因數(shù)。過零調(diào)功方式避免了調(diào)壓方式的不足,但無法限制電流,負載沖擊電流較大,GBC2M-3的調(diào)功調(diào)壓功能提供了兩者優(yōu)點的結(jié)合,可根據(jù)負載情況方便地切換這兩種工作方式。 USER(U1)外部開關(guān)設(shè)置:開路時,為調(diào)功;短路時,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.

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.
