現(xiàn)在跟大家講講根據(jù)負載性質(zhì)選擇不同型號的軟啟動器來選用軟啟動器軟啟動器選型：目前市場上常見的軟啟動器有旁路型軟啟動器、無旁路型軟啟動器、節(jié)能型軟啟動器等。下面我們來一一講它們的功能：旁路型軟啟動器：在電動機達到額定轉(zhuǎn)數(shù)時，用旁路接觸器取代已完成任務的軟啟動器，降低晶閘管的熱損耗，提高其工作效率。也可以用一臺軟啟動器去啟動多臺電動機。無旁路型軟啟動器：晶閘管處于全導通狀態(tài)，電動機工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時重復工作的電動機。節(jié)能型軟啟動器：當電動機負荷較輕時，軟啟動器自動降低施加于電動機定子上的電壓，減少電動機電流勵磁分量，提高電動機功率因數(shù)。軟啟動器如何選規(guī)格?根據(jù)電動機的標稱功率，電流負載性質(zhì)選擇啟動器，一般軟啟動器容量稍大于電動機工作電流，還應考慮保護作用是否完備，例如：缺相保護、短路保護，淄博科恩軟啟動器價格行情、過載保護，淄博科恩軟啟動器價格行情、逆序保護，淄博科恩軟啟動器價格行情、過壓保護、欠壓保護等。淄博科恩軟啟動器價格行情</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淄博科恩軟啟動器價格行情,科恩軟啟動器" src="https://tyunfile.71360.com/UploadFile/keendianqi/637235132859755860/5468229.jpg"></div><p> 軟啟動的好處1．降低電動機的起動電流，減少配電容量，避免增容投資；2．減少起動應力，延長電動機及相關設備的使用壽命；3．平穩(wěn)的起動和軟停車避免了傳統(tǒng)起動設備的喘振問題、水錘效應；4．多種起動模式及寬范圍的電流、電壓等設定，可適應多種負載情況，改善工藝；5．完善可靠的保護功能，更有效的保護電動機及相關設備的安全；軟啟動器的工作原理軟起動主要由串接于電源與被控電動機之間三對反并聯(lián)晶閘管調(diào)壓電路構(gòu)成。現(xiàn)代軟啟動器基本上都采用了電力電子技術(shù)和微機控制技術(shù)，以單片微機作為**控制器控制來完成測量及各種控制算法。因此，山東濟寧軟啟動器具備了很強的功能和靈活性。整個起動過程是數(shù)字化程序軟件控制下自動進行。利用三對晶閘管的電子開關特性，通過MCU或單片機控制其觸發(fā)脈沖的遲早來改變觸發(fā)角的大小。而改變觸發(fā)導通角的大小，又改變了晶閘管的導通時間，**終改變定子繞組的三相電壓的大小。主要元件1、晶閘管：每相一對反并聯(lián)晶閘管，這是主要的功率元件，也是軟啟動器的主要成本之一，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：基本上每個廠家都有自己開發(fā)的主板，市場上也有很多通用主板。淄博科恩軟啟動器</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.減少啟動應力，可以延長電動氣以及其他的相關設備的使用壽命，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、電壓等設定，可適應多種負載情況；</p><div

它的主要構(gòu)成是串接于電源與被控電機之間的三相反并聯(lián)閘管及其電子控制電路。運用不同的方法，控制三相反并聯(lián)閘管的導通角，使被控電機的輸入電壓按不同的要求而變化，就可實現(xiàn)不同的功能。變頻器（Variable-frequencyDrive，VFD）是應用變頻技術(shù)與微電子技術(shù)，通過改變電機工作電源頻率方式來控制交流電動機的電力控制設備。變頻器主要由整流（交流變直流）、濾波、逆變（直流變交流）、制動單元、驅(qū)動單元、檢測單元微處理單元等組成。變頻器靠內(nèi)部IGBT的開斷來調(diào)整輸出電源的電壓和頻率，根據(jù)電機的實際需要來提供其所需要的電源電壓，進而達到節(jié)能、調(diào)速的目的，另外，變頻器還有很多的保護功能，如過流、過壓、過載保護等等。隨著工業(yè)自動化程度的不斷提高，變頻器也得到了非常的應用。軟啟動器和變頻器是兩種完全不同用途的產(chǎn)品。變頻器是用于需要調(diào)速的地方，其輸出不但改變電壓而且同時改變頻率；軟啟動器實際上是個調(diào)壓器，用于電機起動時，輸出只改變電壓并沒有改變頻率。變頻器具備所有軟起動器功能，但它的價格比軟啟動器貴得多，結(jié)構(gòu)也復雜得多。軟啟動器只是改變電源電壓，相當于降壓起動器。變頻器要比軟啟動器復雜得多，價格也貴得多。變頻器也有軟啟動功能。淄博科恩軟啟動器</p><p
