軟啟動器以體積小,轉(zhuǎn)矩可以調(diào)節(jié)、啟動平穩(wěn)、沖擊小并具有軟停機功能等優(yōu)點得到了越來越多的應(yīng)用,大有取代傳統(tǒng)的自耦減壓、星三角變換降壓啟動的趨勢。由于軟啟動器是近年來新發(fā)展起來的啟動設(shè)備,缺少相應(yīng)的設(shè)計及使用經(jīng)驗等籠形異步電動機是應(yīng)用**的用電設(shè)備。由于電動機直接啟動時的沖擊電流很大，特別是大容量電動機直接啟動會對電網(wǎng)及其他負載造成干擾甚至危害電網(wǎng)的安全運行，所以按不同工況，采用許多種減壓啟動方式。早期的方式有串聯(lián)電抗或電阻、串聯(lián)自耦變壓器星三角轉(zhuǎn)換等。從20世紀70年代起，工程上開始推廣利用晶閘管交流調(diào)壓技術(shù)制作的軟啟動器。這種軟啟動器是集電動機軟啟動、軟停車、輕載節(jié)能和多種保護功能于一體的新穎電動機控制裝置，國外稱為softstarter。軟啟動器的構(gòu)成主要是串接于電源與被控電動機之間的三相反并聯(lián)晶閘管及其電子控制電路。軟啟動器的工作原理是，控制電路運用不同的方法，控制三相反并聯(lián)晶閘管的導通角，使電動機輸入電壓從零以預設(shè)的函數(shù)關(guān)系逐漸上升，直至啟動結(jié)束，賦予電動機全電壓，實現(xiàn)軟啟動。在軟啟動過程中，電動機啟動轉(zhuǎn)矩逐漸增加，轉(zhuǎn)速也逐漸增加。在上述基礎(chǔ)上，把功率因數(shù)控制技術(shù)結(jié)合進去。淄博科恩軟啟動器總代理</p><div

style="text-indent:25px">我們都知道電動機在直接啟動時，電流是額定電流的4到7倍，如果電機的功率比較小的時候，對電網(wǎng)的影響不是很大我們就可以直接開始啟動，對于一些電動機功率在7.5KM一下都是可以直接啟動的，對于那些大型的電機（功率特別大的）是不能直接啟動的，所以對于大型電機氣都要使用軟啟動器，下面我們就來介紹一下軟啟動器對電動機的作用軟啟動器就是在大型電機氣在啟動之前，我們給它加的電壓要低于額定電壓，我們常見的軟啟動主要軟啟動器啟動和自耦變壓器降壓啟動，軟啟動器要比自耦變壓器降壓啟動要先進些，其原理也都是一樣的，總結(jié)來說軟啟動器對電動機主要有以下這些作用： 1.可以降低電機的啟動電流，從而減少電容量。 2.減少啟動應(yīng)力，可以延長電動氣以及其他的相關(guān)設(shè)備的使用壽命，維修率低。 3.平穩(wěn)的啟動和軟停車，都是避免了傳統(tǒng)的啟動設(shè)備的喘振問題等。 4.完善可靠的保護功能，能夠有效的保護電機以及設(shè)備的安全。 5.同時還能有效的升降起動電流以及配電電容量。 6.多種起動模式及寬范圍的電流、電壓等設(shè)定，可適應(yīng)多種負載情況；</p><p> 軟起動器就是應(yīng)用**效用**突出的控制設(shè)備,軟啟動器在不同領(lǐng)域、不同行業(yè)甚至是不同設(shè)備上的應(yīng)用往往也有著極大的不同。1、軟起動器在城市雨水排污泵站、污水處理廠中的應(yīng)用雨水排污站的泄水池是雨水、生活污水、工業(yè)污水的集中地，為確保泄水池液位保持在允許的范圍內(nèi)，通過檢測泄水池液位來自動控制排污泵組工作以保證污水的正常排放。2、軟起動器應(yīng)用于自來水廠、加壓泵站清水泵主要實現(xiàn)大功率水泵電機的軟起動、軟停車，重點消除、減弱水錘的危害。當液體在管路系統(tǒng)中受外力突然加速或突然減速、或改變流向就會造成水錘，水錘危害很大，輕則引起管路，系統(tǒng)振動，發(fā)出噪聲，重則造成損壞，甚至使泵房被淹。3、軟起動器在消防泵控制中的應(yīng)用消火栓泵、噴淋泵是工業(yè)和民用建筑消防設(shè)施的重要消防裝備，其運行可靠性極其重要，隨著大中型建設(shè)項目的興建，所配置的消火栓泵、噴淋泵功率、揚程增大，傳統(tǒng)的降壓起動方式凸顯其缺點，尤其高層建筑水錘危害嚴重，給設(shè)備運行帶來不安全因素，目前軟起動在消防泵控制中得到的應(yīng)用。4、軟起動器在在各種類型的深井潛水泵、長軸泵中的應(yīng)用一般深井潛水泵揚程較大，非軟停機時水錘現(xiàn)象明顯。

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電機啟動時，由電子電路控制晶閘管的導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。當電動機啟動完成并達到額定電壓時，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通角，使電機端電壓慢慢降低至0，從而實現(xiàn)軟停機。淄博科恩軟啟動器總代理</p><p
