即起動過程中出現(xiàn)二次沖擊電流。軟起動與傳統(tǒng)減壓起動方式的不同之處是:無沖擊電流。軟起動器在起動電機時,通過逐漸增大晶閘管導(dǎo)通角,使電機起動電流從零線性上升至設(shè)定值。恒流起動。軟起動器可以引入電流閉環(huán)控制,使電機在起動過程中保持恒流,確保電機平穩(wěn)起動。⑶根據(jù)負載情況及電網(wǎng)繼電保護特性選擇,可自由地?zé)o級調(diào)整至的起動電流。適用于重載并需克服較大靜摩擦的起動場合。電壓雙斜坡起動:在起動過程中,電機的輸出力矩隨電壓增加,軟啟動器(圖3)軟啟動器(圖3)在起動時提供一個初始的起動電壓Us,Us根據(jù)負載可調(diào),將Us調(diào)到大于負載靜磨擦力矩,使負載能立即開始轉(zhuǎn)動。這時輸出電壓從Us開始按一定的斜率上升(斜率可調(diào))。

電流上升變化的速率是可以根據(jù)電動機負載調(diào)整設(shè)定。電流上升速率大,則起動轉(zhuǎn)矩大,起動時間短。該起動方式是應(yīng)用多的起動方式,尤其適用于風(fēng)機、泵類負載的起動。階躍起動:開機,即以短時間,使起動電流迅速達到設(shè)定值,即為階躍起動。軟啟動器(圖2)軟啟動器(圖2)通過調(diào)節(jié)起動電流設(shè)定值,可以達到快速起動效果。脈沖沖擊起動:在起動開始階段,讓晶閘管在極短時間內(nèi),以較大電流導(dǎo)通一段時間后回落,再按原設(shè)定值線性上升,連入恒流起動。該起動方法,在一般負載中較少應(yīng)用,適用于重載并需克服較大靜摩擦的起動場合?;\型電機傳統(tǒng)的減壓起動方式有Y-q起動、自耦減壓起動、電抗器起動等。這些起動方式都屬于有級減壓起動,存在明顯缺點。

傳統(tǒng)的直流調(diào)速技術(shù)因體積大故障率高而應(yīng)用受限。20世紀60年代以后,電力電子器件普遍應(yīng)用了晶閘管及其升級產(chǎn)品。但其調(diào)速性能遠遠無法滿足需要。1968年以丹佛斯為代表的高技術(shù)企業(yè)開始批量化生產(chǎn)變頻器,開啟了變頻器工業(yè)化的新時代。20世紀70年代開始,脈寬調(diào)制變壓變頻(PWM-VVVF)調(diào)速的研究得到突破,20世紀80年代以后微處理器技術(shù)的完善使得各種優(yōu)化算法得以容易的實現(xiàn)。20世紀80年代中后期,美、日、德、英等發(fā)達國家的VVVF變頻器技術(shù)實用化,商品投入市場,得到了廣泛應(yīng)用。早的變頻器可能是日本人買了英國專利研制的。不過美國和德國憑借電子元件生產(chǎn)和電子技術(shù)的優(yōu)勢,高端產(chǎn)品迅速搶占市場。步入21世紀后。

無紙記錄儀和無線通訊技術(shù)的有機結(jié)合,有效的解決了油田地域十分分散,而又急需解決數(shù)據(jù)遠傳和自動控制問題。本文向你介紹彩色無紙記錄儀在國內(nèi)某大型油田采油集、輸系統(tǒng)中的應(yīng)用一例?,F(xiàn)場情況編輯油田油井十分分散,往往離采油廠幾公里甚至幾十公里,因此,輸送原油及天然氣的管線遍布油區(qū)各地,要想實時獲得每口井以及各個區(qū)域的采油/氣量十分困難,多年來,各大油田的采油站、聯(lián)合站、運銷處等大都采用各采油站填寫報表的形式統(tǒng)計每天每口井以及各個區(qū)域的采油/氣量,然后通過累加的方式獲得月產(chǎn)量,這樣的方法不但要花費大量的人力和物力,很易出錯,而且在時間上也嚴重滯后,采油廠、油田很難動態(tài)掌握每口井甚至每個區(qū)域的采油情況,對突發(fā)事件難以做出迅速反應(yīng)。
