starter）是一種集電機(jī)軟起動(dòng)、軟停車、多種保護(hù)功能于一體的新穎電機(jī)控制裝置。它的主要構(gòu)成是串接于電源與被控電機(jī)之間的三相反并聯(lián)晶閘管及其電子控制電路。軟啟動(dòng)器工作原理：軟啟器采用三相反并聯(lián)晶閘管作為調(diào)壓器，將其接入電源和電動(dòng)機(jī)定子之間。這種電路如三相全控橋式整流電路。使用軟啟動(dòng)器啟動(dòng)電動(dòng)機(jī)時(shí)，晶閘管的輸出電壓逐漸增加，電動(dòng)機(jī)逐漸加速，直到晶閘管全導(dǎo)通，電動(dòng)機(jī)工作在額定電壓的機(jī)械特性上，實(shí)現(xiàn)平滑啟動(dòng)，降低啟動(dòng)電流，避免啟動(dòng)過流跳閘。軟啟動(dòng)器起動(dòng)方式：斜坡升壓軟起動(dòng)、斜坡恒流軟起動(dòng)、階躍起動(dòng)、脈沖沖擊起動(dòng)。軟啟動(dòng)器的作用：軟起動(dòng)時(shí)具有起動(dòng)電流小、起動(dòng)速度平穩(wěn)可靠、對(duì)電網(wǎng)沖擊小等優(yōu)點(diǎn)，且起動(dòng)曲線可根據(jù)現(xiàn)場實(shí)際工況調(diào)整，從而減少了起動(dòng)時(shí)對(duì)設(shè)備的沖擊力，降低了對(duì)設(shè)備的損害，延長了使用壽命。主要目的是降低起動(dòng)電壓與電流。淄博科恩軟啟動(dòng)器公司誠摯的歡迎業(yè)界新朋老友走進(jìn)科恩電氣！</p><div

style="text-indent:25px">我們都知道電動(dòng)機(jī)在直接啟動(dòng)時(shí)，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(shí)候，對(duì)電網(wǎng)的影響不是很大我們就可以直接開始啟動(dòng)，對(duì)于一些電動(dòng)機(jī)功率在7.5KM一下都是可以直接啟動(dòng)的，對(duì)于那些大型的電機(jī)（功率特別大的）是不能直接啟動(dòng)的，所以對(duì)于大型電機(jī)氣都要使用軟啟動(dòng)器，下面我們就來介紹一下軟啟動(dòng)器對(duì)電動(dòng)機(jī)的作用軟啟動(dòng)器就是在大型電機(jī)氣在啟動(dòng)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(dòng)主要軟啟動(dòng)器啟動(dòng)和自耦變壓器降壓啟動(dòng)，軟啟動(dòng)器要比自耦變壓器降壓啟動(dòng)要先進(jìn)些，其原理也都是一樣的，總結(jié)來說軟啟動(dòng)器對(duì)電動(dòng)機(jī)主要有以下這些作用： 1.可以降低電機(jī)的啟動(dòng)電流，從而減少電容量。 2.減少啟動(dòng)應(yīng)力，可以延長電動(dòng)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(dòng)和軟停車，都是避免了傳統(tǒng)的啟動(dòng)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(shí)還能有效的升降起動(dòng)電流以及配電電容量。 6.多種起動(dòng)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 style="text-indent:25px">就損傷特殊連接的轉(zhuǎn)子馬達(dá)或線路中的變壓器。這種方法的缺點(diǎn)是增加了馬達(dá)費(fèi)用、昂貴的開關(guān)裝置、降壓部件、必須的機(jī)械裝置維護(hù)、扭矩階躍變化和起動(dòng)時(shí)產(chǎn)生的加速度。通過改進(jìn)可控硅整流谷(SCR)而研創(chuàng)的一種減小電壓的起動(dòng)器，它適用于控制油井大功率值。其基本線路使用六個(gè)連接的可控硅整流器作為三個(gè)全控交流開關(guān)。每個(gè)電源相和馬達(dá)之間安置一個(gè)開關(guān).它是在一個(gè)全橋控制之中限制電流。當(dāng)按圖連接時(shí)，在每個(gè)半循環(huán)期間電路能用改變每個(gè)可控硅整流器接通點(diǎn)來控制負(fù)載的交流功率，使用正確的時(shí)間信號(hào)把它加到可控硅整流器的整流柵進(jìn)行整流。在每個(gè)半循環(huán)中逐漸變化相后角，能平穩(wěn)增加馬達(dá)的功率通量。當(dāng)按“起動(dòng)”按鈕時(shí)，電流迅速上升到預(yù)置的滿載安培數(shù)值，通常是40%.該數(shù)值剛剛處于馬達(dá)負(fù)載裝置起動(dòng)扭矩之下。從這一點(diǎn)，電流將緩慢地開始上升到某些預(yù)置的滿載安培數(shù)值，該數(shù)值保證馬達(dá)在正確的電壓值運(yùn)轉(zhuǎn).時(shí)間間隔可從1s調(diào)到30s.在軟起動(dòng)時(shí)間，電壓和馬達(dá)速度也是緩慢地變化。當(dāng)馬達(dá)電流下降時(shí)，就表示馬達(dá)運(yùn)轉(zhuǎn)正常，此時(shí)起動(dòng)器系統(tǒng)對(duì)電路沒有較大的形響.若在“軟”起動(dòng)循環(huán)完成之后，馬達(dá)電流超過預(yù)置數(shù)值115%滿軟安培數(shù)達(dá)4s。該控制器將使用一個(gè)電流減速階躍關(guān)閉設(shè)備。科恩電氣交通便利，地理位置優(yōu)越。</p><div

軟起動(dòng)器具有軟起動(dòng)、軟停止、泵控制功能、定時(shí)低速運(yùn)行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動(dòng)力設(shè)備控制中具有傳統(tǒng)降壓起動(dòng)器不可比擬的優(yōu)越性。三相異步電動(dòng)機(jī)有很多優(yōu)點(diǎn)，但也有兩個(gè)致命的弱點(diǎn)：一是啟動(dòng)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(gè)典型的產(chǎn)品改善了異步電動(dòng)機(jī)這兩個(gè)弱點(diǎn)，一是變頻器，二是軟啟動(dòng)器。變頻器改善異步電動(dòng)機(jī)的調(diào)速性能；軟起動(dòng)在起動(dòng)時(shí)間ts內(nèi)，電機(jī)的端電壓從設(shè)定的初始值逐漸增至滿壓，電機(jī)平滑、無級(jí)地加速。同時(shí)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(shí)脫扣器在電機(jī)起動(dòng)時(shí)誤跳閘。過載保護(hù)功能一般電機(jī)的過載保護(hù)是通過熱元件來實(shí)現(xiàn)的，熱元件在電動(dòng)機(jī)起動(dòng)過程中很難避開電機(jī)的起動(dòng)電流而產(chǎn)生誤動(dòng)作。為避免誤動(dòng)，用戶常加大熱元件的動(dòng)作電流，因而使得過載保護(hù)的靈敏度不夠，使過載保護(hù)形同虛設(shè)。而軟起動(dòng)器內(nèi)置的過載保護(hù)功能是根據(jù)起動(dòng)負(fù)荷的輕重(即起動(dòng)時(shí)間的長短)來選擇不同的脫扣特性曲線，以避免在起動(dòng)過程中誤跳。由于它的過載保護(hù)是可編程的，軟啟動(dòng)器廠家從而為用戶提供了更大的靈活性。科恩電氣秉承“信譽(yù)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(dòng)器公司</p><p
