高壓軟起動器對信號的檢測比低壓軟起動器要求更高。高壓軟起動器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動器所用的真空接觸器和真空斷路器在其分?jǐn)嗪烷]合過程中會產(chǎn)生大量的電磁干擾。所以對檢測到的信號不僅要進行硬件濾波，也要進行軟件濾波，去掉干擾信號。軟起動器在完成起動過程后，要切換到旁路運行狀態(tài)，如何平滑地切換到運行狀態(tài)，這也是軟起動器的一個難點，如何選準(zhǔn)旁路點非常重要。旁路點早了，電流沖擊非常大，即使在低壓條件下，也會造成三相電源中斷路器跳閘，甚至?xí)p壞斷路器。高壓條件下危害更大。旁路點遲了，電機抖動得厲害，影響負(fù)載正常工作。因此，旁路信號的硬件檢測電路必須非常精確，并且程序處理也要恰到好處。綜上所述，盡管低壓軟起動器和高壓軟起動器的基本原理一致，但高壓軟起動器存在的諸多技術(shù)難題，使得在低壓軟起動器遍地開花的情況下，高壓軟起動器的成熟產(chǎn)品并不多見。淄博科恩軟啟動器總代理科恩電氣具有一支經(jīng)驗豐富、技術(shù)力量過硬的專業(yè)技術(shù)人才管理團隊。</p><div

軟起動器具有軟起動、軟停止、泵控制功能、定時低速運行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動力設(shè)備控制中具有傳統(tǒng)降壓起動器不可比擬的優(yōu)越性。三相異步電動機有很多優(yōu)點，但也有兩個致命的弱點：一是啟動性能差；二是調(diào)速性能差。隨著電力半導(dǎo)體技術(shù)的發(fā)展以及大功率晶體管在工業(yè)控制領(lǐng)域里的應(yīng)用，有兩個典型的產(chǎn)品改善了異步電動機這兩個弱點，一是變頻器，二是軟啟動器。變頻器改善異步電動機的調(diào)速性能；軟起動在起動時間ts內(nèi)，電機的端電壓從設(shè)定的初始值逐漸增至滿壓，電機平滑、無級地加速。同時ts可調(diào)節(jié)(通常在60s之間),這有利于與低壓斷路器之間的配合，防止低壓斷路器的瞬時脫扣器在電機起動時誤跳閘。過載保護功能一般電機的過載保護是通過熱元件來實現(xiàn)的，熱元件在電動機起動過程中很難避開電機的起動電流而產(chǎn)生誤動作。為避免誤動，用戶常加大熱元件的動作電流，因而使得過載保護的靈敏度不夠，使過載保護形同虛設(shè)。而軟起動器內(nèi)置的過載保護功能是根據(jù)起動負(fù)荷的輕重(即起動時間的長短)來選擇不同的脫扣特性曲線，以避免在起動過程中誤跳。由于它的過載保護是可編程的，軟啟動器廠家從而為用戶提供了更大的靈活性。 </p><p> 電機軟啟動器是一種集軟啟動、軟停車、輕載節(jié)能和多功能保護于一體的新穎電機控制裝置，的應(yīng)用于風(fēng)機、水泵、輸送類及壓縮機等負(fù)載，是傳統(tǒng)的星/三角轉(zhuǎn)換、自耦降壓磁控降壓等降壓設(shè)備的理想換代產(chǎn)品。在某些變頻器大材小用的場合，也能使用軟啟動器來進行代替。節(jié)約了成本的同時，也使不必要的浪費得到控制。那么是哪些方面造就了電機軟啟動器的高性價比呢?1、啟動方式：根據(jù)負(fù)載特點選擇不同的啟動模式及參數(shù)設(shè)置，可很大程度的使電動機實現(xiàn)比較好的啟動效果，三種啟動方式：電壓斜坡啟動——可得到比較大的輸出扭矩;限流啟動——可有效地限制啟動電流;點動——可實現(xiàn)試車調(diào)試功能。2、高技術(shù)性能：由于采用了高性能微處理器及強大的軟件支持功能使控制電路得以簡化，無需對電路參數(shù)進行調(diào)整，即可獲得一致、準(zhǔn)確及快速的執(zhí)行速度;**度抗干擾功能。3、高可靠性：電機軟啟動器所有電器元件均經(jīng)過嚴(yán)格的篩選，其主控板還須經(jīng)過72小時高溫循環(huán)試驗和振動試驗，從而保證了出廠產(chǎn)品的高可靠性。4、優(yōu)化的結(jié)構(gòu)：獨特緊湊的模塊化結(jié)構(gòu)及上進線下出線的連接方式，非常方便用戶的集成、成套。5、鍵盤設(shè)置功能：電機軟啟動器擁有便捷直觀的操作顯示鍵盤，可根據(jù)不同負(fù)載。科恩電氣生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。</p><div

style="text-indent:25px">在電動機啟動時，降低加到電動機定子繞組的電壓可以減小電動機的啟動電流。一般降壓啟動是指電動機在啟動過程中加在電動機定子繞組的電壓變化是瞬間突變的，主要有“Y—△”降壓啟動和自藕變壓器降壓啟動等;而軟啟動是使用調(diào)壓裝置在規(guī)定的啟動時間內(nèi)，自動地將啟動電壓連續(xù)、平滑地上升，直到達(dá)到額定電壓。若采用一般降壓啟動，則啟動過程是跳躍的、不平滑的，所以又叫作硬啟動，對生產(chǎn)工藝要求穩(wěn)啟動的場合不宜采用。而軟啟動從初始電壓開始電壓連續(xù)平穩(wěn)地增大，在啟動過程中電動機的轉(zhuǎn)矩是平滑的而不是跳躍的，啟動過程是平穩(wěn)的，所以叫軟啟動。軟啟動器工作原理是當(dāng)電機啟動時，由電子電路控制晶閘管的導(dǎo)通角使電機的端電壓以設(shè)定的速度逐漸升高，一直升到全電壓，使電機實現(xiàn)無沖擊啟動到控制電動機軟啟動的過程。當(dāng)電動機啟動完成并達(dá)到額定電壓時，使三相旁路接觸器閉合，電動機直接投入電網(wǎng)運行。如果是輕載，則在正常運行時，也保持所需的較低端電壓，使電機的功率因數(shù)升高，效率增大。在電機停機時，也通過控制晶閘管的導(dǎo)通角，使電機端電壓慢慢降低至0，從而實現(xiàn)軟停機?？贫麟姎獗小靶抛u保證，質(zhì)量質(zhì)優(yōu)，服務(wù)至上”的企業(yè)宗旨。淄博科恩軟啟動器</p><p
