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)，淄博科恩軟啟動(dòng)器生產(chǎn)商，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，淄博科恩軟啟動(dòng)器生產(chǎn)商，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，淄博科恩軟啟動(dòng)器生產(chǎn)商。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。淄博科恩軟啟動(dòng)器生產(chǎn)商</p><div

軟啟動(dòng)的好處1．降低電動(dòng)機(jī)的起動(dòng)電流，減少配電容量，避免增容投資；2．減少起動(dòng)應(yīng)力，延長電動(dòng)機(jī)及相關(guān)設(shè)備的使用壽命；3．平穩(wěn)的起動(dòng)和軟停車避免了傳統(tǒng)起動(dòng)設(shè)備的喘振問題、水錘效應(yīng)；4．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，改善工藝；5．完善可靠的保護(hù)功能，更有效的保護(hù)電動(dòng)機(jī)及相關(guān)設(shè)備的安全；軟啟動(dòng)器的工作原理軟起動(dòng)主要由串接于電源與被控電動(dòng)機(jī)之間三對(duì)反并聯(lián)晶閘管調(diào)壓電路構(gòu)成?，F(xiàn)代軟啟動(dòng)器基本上都采用了電力電子技術(shù)和微機(jī)控制技術(shù)，以單片微機(jī)作為**控制器控制來完成測(cè)量及各種控制算法。因此，山東濟(jì)寧軟啟動(dòng)器具備了很強(qiáng)的功能和靈活性。整個(gè)起動(dòng)過程是數(shù)字化程序軟件控制下自動(dòng)進(jìn)行。利用三對(duì)晶閘管的電子開關(guān)特性，通過MCU或單片機(jī)控制其觸發(fā)脈沖的遲早來改變觸發(fā)角的大小。而改變觸發(fā)導(dǎo)通角的大小，又改變了晶閘管的導(dǎo)通時(shí)間，**終改變定子繞組的三相電壓的大小。主要元件1、晶閘管：每相一對(duì)反并聯(lián)晶閘管，這是主要的功率元件，也是軟啟動(dòng)器的主要成本之一，國內(nèi)做反并聯(lián)晶閘管的廠家有很多，從便宜的到貴的都有，質(zhì)量更是參差不齊。2、控制主板：基本上每個(gè)廠家都有自己開發(fā)的主板，市場(chǎng)上也有很多通用主板。 </p><p style="text-indent:25px">在電動(dòng)機(jī)啟動(dòng)時(shí)，降低加到電動(dòng)機(jī)定子繞組的電壓可以減小電動(dòng)機(jī)的啟動(dòng)電流。一般降壓啟動(dòng)是指電動(dòng)機(jī)在啟動(dòng)過程中加在電動(dòng)機(jī)定子繞組的電壓變化是瞬間突變的，主要有“Y—△”降壓啟動(dòng)和自藕變壓器降壓啟動(dòng)等;而軟啟動(dòng)是使用調(diào)壓裝置在規(guī)定的啟動(dòng)時(shí)間內(nèi)，自動(dòng)地將啟動(dòng)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(dòng)，則啟動(dòng)過程是跳躍的、不平滑的，所以又叫作硬啟動(dòng)，對(duì)生產(chǎn)工藝要求穩(wěn)啟動(dòng)的場(chǎng)合不宜采用。而軟啟動(dòng)從初始電壓開始電壓連續(xù)平穩(wěn)地增大，在啟動(dòng)過程中電動(dòng)機(jī)的轉(zhuǎn)矩是平滑的而不是跳躍的，啟動(dòng)過程是平穩(wěn)的，所以叫軟啟動(dòng)。軟啟動(dòng)器工作原理是當(dāng)電機(jī)啟動(dòng)時(shí)，由電子電路控制晶閘管的導(dǎo)通角使電機(jī)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(jī)實(shí)現(xiàn)無沖擊啟動(dòng)到控制電動(dòng)機(jī)軟啟動(dòng)的過程。當(dāng)電動(dòng)機(jī)啟動(dòng)完成并達(dá)到額定電壓時(shí)，使三相旁路接觸器閉合，電動(dòng)機(jī)直接投入電網(wǎng)運(yùn)行。如果是輕載，則在正常運(yùn)行時(shí)，也保持所需的較低端電壓，使電機(jī)的功率因數(shù)升高，效率增大。在電機(jī)停機(jī)時(shí)，也通過控制晶閘管的導(dǎo)通角，使電機(jī)端電壓慢慢降低至0，從而實(shí)現(xiàn)軟停機(jī)。</p><div

高壓軟起動(dòng)器對(duì)信號(hào)的檢測(cè)比低壓軟起動(dòng)器要求更高。高壓軟起動(dòng)器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動(dòng)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(huì)產(chǎn)生大量的電磁干擾。所以對(duì)檢測(cè)到的信號(hào)不僅要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號(hào)。軟起動(dòng)器在完成起動(dòng)過程后，要切換到旁路運(yùn)行狀態(tài)，如何平滑地切換到運(yùn)行狀態(tài)，這也是軟起動(dòng)器的一個(gè)難點(diǎn)，如何選準(zhǔn)旁路點(diǎn)非常重要。旁路點(diǎn)早了，電流沖擊非常大，即使在低壓條件下，也會(huì)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(diǎn)遲了，電機(jī)抖動(dòng)得厲害，影響負(fù)載正常工作。因此，旁路信號(hào)的硬件檢測(cè)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(dòng)器和高壓軟起動(dòng)器的基本原理一致，但高壓軟起動(dòng)器存在的諸多技術(shù)難題，使得在低壓軟起動(dòng)器遍地開花的情況下，高壓軟起動(dòng)器的成熟產(chǎn)品并不多見。淄博科恩軟啟動(dòng)器生產(chǎn)商</p><p
