style="text-indent:25px">我們都知道電動機(jī)在直接啟動時，電流是額定電流的4到7倍，如果電機(jī)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(jī)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(jī)（功率特別大的）是不能直接啟動的，所以對于大型電機(jī)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(jī)的作用軟啟動器就是在大型電機(jī)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(jìn)些，其原理也都是一樣的，總結(jié)來說軟啟動器對電動機(jī)主要有以下這些作用： 1.可以降低電機(jī)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(hù)功能，能夠有效的保護(hù)電機(jī)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(fù)載情況；</p><p> 交流感應(yīng)電動機(jī)在直接啟動時存在著兩點缺點，首先它的啟動電流可高達(dá)額定電流的5－7倍，這要求電網(wǎng)寬裕量比較大，而且降低電器控制設(shè)備的使用壽命，增加維護(hù)成本；其次，啟動轉(zhuǎn)矩可達(dá)正常轉(zhuǎn)矩的兩倍，這會對負(fù)載產(chǎn)生沖擊，增加傳動部件的磨損和額外維護(hù)?；谝陨显颍a(chǎn)生交流感應(yīng)電動機(jī)降壓啟動設(shè)備。傳統(tǒng)的降壓啟動方法有Y/△啟動和自耦變壓器降壓啟動兩種，每種都有各自的缺點。電動機(jī)用Y/△啟動設(shè)備啟動時，在切換瞬間會出現(xiàn)很高的電流尖峰，產(chǎn)生破壞性的動態(tài)轉(zhuǎn)矩，其引起的機(jī)械振動對電動機(jī)轉(zhuǎn)子、軸連接器、中間齒輪以及負(fù)載等都非常有害；自耦變壓器降壓啟動設(shè)備體積龐大、成本高，而且還存在與負(fù)載匹配的電動機(jī)轉(zhuǎn)矩很難控制等缺點。由于傳統(tǒng)的降壓啟動設(shè)備存在諸多缺點，這才出現(xiàn)了電子式數(shù)字軟啟動裝置。

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(jī)的軟起動、軟停車，重點消除、減弱水錘的危害。當(dāng)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(yán)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(jī)時水錘現(xiàn)象明顯。淄博科恩軟啟動器全國發(fā)貨</p><p

電動機(jī)的啟動指標(biāo)啟動（startion）是指電動機(jī)從靜止?fàn)顟B(tài)開始轉(zhuǎn)動起來．直至達(dá)到穩(wěn)定運行。對干任何一臺電動機(jī)．在啟動時．都有下列兩個基本的要求。啟動轉(zhuǎn)矩要足夠大．只有Tｎ>TL時．電動機(jī)才能改變原來的靜止?fàn)顟B(tài)．拖動生產(chǎn)機(jī)械運轉(zhuǎn)。一般要求Tn≥()TL,Tn越大于TL．啟動過程所需要的時間就越短。啟動電流不要超過允許范圍。對三相異步電動機(jī)來說．由干啟動瞬間s=1,旋轉(zhuǎn)磁場與轉(zhuǎn)子之間的相對運動速度很大．轉(zhuǎn)子電路的感應(yīng)電動勢及電流都很大．所以．啟動電流遠(yuǎn)大干額定電流．在電源容量與電動機(jī)的額定功率相比不是足夠大時．會引起輸電線路上電壓降的增加．造成供電電壓的明顯下降．不僅影響了同一供電系統(tǒng)中其他負(fù)載的工作，而且會延長電動機(jī)本身的啟動時間。此外在啟動過干頻繁時，還會引起電動機(jī)過熱。在這兩種情況下．就必須設(shè)法減小啟動電流．下面分別介紹籠型和繞線型異步電動饑的啟動方法．異步電動機(jī)啟動籠型異步電動機(jī)的直接啟動直接啟動又稱為全壓啟動．就是將電動機(jī)的定子繞組直接加上額定電壓啟動．直接啟動電流雖然很大．但因啟動時間很短．而且隨著轉(zhuǎn)子轉(zhuǎn)動起來后。電流很快減小．只要啟動不過于頻繁．不致引起電動機(jī)過熱。淄博科恩軟啟動器全國發(fā)貨</p><p
