2.當(dāng)我們在使用電機軟啟動器時，使電動機制動停機，主要的原因是由于晶閘管不導(dǎo)通，所以我們在檢修電動機或線路時，必須要先斷開供電電源，淄博科恩軟啟動器批發(fā)價格，這樣可以使軟啟動器與電源之間增設(shè)斷路器

采用矢量控制方式的通用變頻器不僅可在調(diào)速范圍內(nèi)與直流電動機相匹配，而且可以控制異步電動機產(chǎn)生的轉(zhuǎn)矩。轉(zhuǎn)矩控制根據(jù)不同的數(shù)學(xué)算法其功能結(jié)構(gòu)也不相同，如圖所示是一種典型的采用矢量方式實現(xiàn)的轉(zhuǎn)矩控制功能框圖。先是根據(jù)轉(zhuǎn)矩設(shè)定值計算出轉(zhuǎn)差頻率，并與變頻器獲得的反饋速度(一般用編碼器PG)或是直接推算的電動機速度相加，在速度限制下輸出同步頻率。很顯然，在轉(zhuǎn)矩控制方式下，速度調(diào)節(jié)器ASR并不起直接作用，也無法控制速度。轉(zhuǎn)矩控制時，變頻器的輸出頻率自動負(fù)載速度的變化，但輸出頻率的變化受設(shè)定的加速和減速時間影響，如需要加快的速度，需要將加速和減速時間設(shè)得短一些。轉(zhuǎn)矩分正向轉(zhuǎn)矩和反向轉(zhuǎn)矩，其設(shè)定可以通過模擬量端子的電平來決定，該轉(zhuǎn)矩方向與運行指令的方向（即正轉(zhuǎn)和反轉(zhuǎn)）無關(guān)。當(dāng)模擬量信號為0～10V時，為正轉(zhuǎn)矩，即電動機正轉(zhuǎn)方向的轉(zhuǎn)矩指令（從電動機的輸出軸看是逆時針轉(zhuǎn)）；當(dāng)模擬量信號為-10～0V時，為負(fù)轉(zhuǎn)矩，即電動機反轉(zhuǎn)方向的轉(zhuǎn)矩指令（從電動機的輸出軸看是順時針轉(zhuǎn)）。淄博科恩軟啟動器批發(fā)價格科恩電氣嚴(yán)格控制原材料的選取與生產(chǎn)工藝的每個環(huán)節(jié)，保證產(chǎn)品質(zhì)量不出問題。</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(dǎo)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(yīng)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(shè)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(jìn)而達(dá)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(yīng)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(fù)雜得多。軟啟動器只是改變電源電壓，相當(dāng)于降壓起動器。變頻器要比軟啟動器復(fù)雜得多，價格也貴得多。變頻器也有軟啟動功能。 </p><p> 高壓軟起動器對信號的檢測比低壓軟起動器要求更高。高壓軟起動器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動器所用的真空接觸器和真空斷路器在其分?jǐn)嗪烷]合過程中會產(chǎn)生大量的電磁干擾。所以對檢測到的信號不僅要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號。軟起動器在完成起動過程后，要切換到旁路運行狀態(tài)，如何平滑地切換到運行狀態(tài)，這也是軟起動器的一個難點，如何選準(zhǔn)旁路點非常重要。旁路點早了，電流沖擊非常大，即使在低壓條件下，也會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。旁路點遲了，電機抖動得厲害，影響負(fù)載正常工作。因此，旁路信號的硬件檢測電路必須非常精確，并且程序處理也要恰到好處。綜上所述，盡管低壓軟起動器和高壓軟起動器的基本原理一致，但高壓軟起動器存在的諸多技術(shù)難題，使得在低壓軟起動器遍地開花的情況下，高壓軟起動器的成熟產(chǎn)品并不多見。科恩電氣憑著良好的信用、優(yōu)良的服務(wù)與多家企業(yè)建立了長期的合作關(guān)系。</p><div

軟啟動器（softstarter）是一種集電機軟起動、軟停車、多種保護功能于一體的新穎電機控制裝置，國外稱為SoftStarter。從短期來看軟起動將仍然以各種形式的降壓（限流）軟起動為它的主要形式，從市場的理論來講，軟起動器的性價比高將會占據(jù)市場的巨大份額。但是由于人們對于軟起動器的各種性能側(cè)重面不同，這就使得了各類軟起產(chǎn)品在市場上都會有自己的一席之地?？陀^的方面有：使用的環(huán)境（溫度、濕度變化范圍）、起動負(fù)載的輕重、使用的頻繁度、防爆、防塵燈方面的因素。例如如果是南方的客戶則不會很在意于液態(tài)軟起動液阻會不會結(jié)冰。主觀方面：主管人員的知識水平、維護人員的技術(shù)水平以及用戶單位的管理水品等等都可以成為主觀方面的因素。例如在一些主管技術(shù)人員知識老化的單位中，他們可能不會樂意選用技術(shù)含量高的產(chǎn)品。淄博科恩軟啟動器批發(fā)價格</p><p
