高壓固態軟啟動柜在西鋼燒結廢氣治理中的應用

2019-09-26

髙壓固態軟起動柜詳細介紹:

髙壓(ya)固態軟(ruan)(ruan)起動(dong)(dong)關(guan)鍵(jian)適用10kV下列的(de)中(zhong)髙壓(ya)交(jiao)流(liu)電(dian)機,選用優秀DSP控(kong)制(zhi)系(xi)統、電(dian)力電(dian)子技(ji)術。髙壓(ya)軟(ruan)(ruan)起動(dong)(dong)器是用好幾個可控(kong)硅(gui)串并聯而成,能(neng)(neng)(neng)夠(gou)考慮不(bu)一樣的(de)電(dian)流(liu)量和工(gong)作(zuo)電(dian)壓(ya)規定,操(cao)縱可控(kong)硅(gui)的(de)開啟(qi)角就能(neng)(neng)(neng)夠(gou)操(cao)縱輸(shu)出(chu)工(gong)作(zuo)電(dian)壓(ya)的(de)尺寸。髙壓(ya)交(jiao)流(liu)電(dian)機軟(ruan)(ruan)起動(dong)(dong)器具備重量輕、功率低、銷售電(dian)價(jia)、高靈敏、無觸(chu)點、免維護保養、無空氣污染、安裝便捷(jie)等(deng)優勢。與別的(de)傳統式的(de)啟(qi)動(dong)(dong)方式 相較為,其(qi)獨(du)有的(de)智能(neng)(neng)(neng)控(kong)制(zhi)系(xi)統方法,既(ji)能(neng)(neng)(neng)夠(gou)便捷(jie)精確(que)地設(she)定起動(dong)(dong)轉矩、啟(qi)動(dong)(dong)電(dian)流(liu)量、啟(qi)動(dong)(dong)時間、關(guan)機時間等(deng)主(zhu)要參數,又能(neng)(neng)(neng)夠(gou)與微(wei)型機、PLC等(deng)開展聯網控(kong)制(zhi)。本(ben)新項目選用RNMV2000系(xi)列產品(pin)髙壓(ya)固態硬盤軟(ruan)(ruan)起動(dong)(dong)器。

髙壓固態軟起動柜的原(yuan)理(li)RNMV2000系列產(chan)品的操縱關鍵是微控(kong)(kong)制器 CPUO這一微控(kong)(kong)制器自動控(kong)(kong)制系統能夠對電機開展

啟(qi)動(dong)(dong)(dong)和維護。CPU對(dui)SCR開展相(xiang)(xiang)位(wei)角開啟(qi)操(cao)縱以減少加進電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)上(shang)的工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)壓,使電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)上(shang)的工(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)(dian)流量光(guang)滑地提升電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的轉距,直至電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)加快到飛速運作(zuo)情況,進而降低了電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)起(qi)動(dong)(dong)(dong)時對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)網、電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)自身(shen) 、相(xiang)(xiang)接(jie)機(ji)(ji)(ji)器設(she)(she)備(bei)的電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設(she)(she)備(bei)及(ji)機(ji)(ji)(ji)械設(she)(she)備(bei)沖擊(ji)性。當電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)超過(guo)一切正常轉速比后,雙回路供電(dian)(dian)(dian)(dian)(dian)(dian)交流接(jie)觸器接(jie)入。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)(ji)起(qi)動(dong)(dong)(dong)結(jie)束后,髙(gao)壓軟起(qi)動(dong)(dong)(dong)器再次監(jian)控器電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)并(bing)出(chu)示(shi)(shi)各種各樣常見故障維護。其操(cao)縱基本原理如圖所示(shi)(shi)2圖示(shi)(shi)。RNMV2000系列產品出(chu)示(shi)(shi)了3種啟(qi)動(dong)(dong)(dong)方式:

(1)工作(zuo)電(dian)(dian)壓陡(dou)坡(po)啟(qi)動(dong)(dong)方式原始轉(zhuan)距(ju)設置為電(dian)(dian)機(ji)恰好能推動(dong)(dong)負荷(he)旋轉(zhuan)時(shi)(shi)的值,隨(sui)后工作(zuo)電(dian)(dian)壓慢慢地光滑(hua)升高,在(zai)限制的陡(dou)坡(po)時(shi)(shi)間和電(dian)(dian)動(dong)(dong)機(ji)起動(dong)(dong)電(dian)(dian)流量范圍之內,使(shi)電(dian)(dian)機(ji)光滑(hua)地超過飛速運(yun)行。本(ben)新項目的電(dian)(dian)機(ji)設定為具備(bei)制人數(shu)作(zuo)用的工作(zuo)電(dian)(dian)壓陡(dou)坡(po) 

(2)制人數(shu)啟動方式

啟(qi)動時,電流(liu)量迅速(su)(su)提升(sheng)到(dao)規(gui)定(ding)值,始(shi)終到(dao)電機飛速(su)(su)運作。

(3)輕載啟動方式

這(zhe)類啟動方(fang)式主要用于電機(ji)帶動大慣(guan)性力(li)負荷(he)如濕式球磨機(ji)等,增加8 s的轉(zhuan)換(huan)時間來(lai)確保(bao)不容易(yi)由于太早(zao)轉(zhuan)換(huan)產生過大的電流量沖擊(ji)性。
