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)閘管及其電子控制電路。運(yùn)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(jī)的輸入電壓按不同的要求而變化，淄博科恩軟啟動器報(bào)價(jià)，就可實(shí)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(jī)工作電源頻率方式來控制交流電動機(jī)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），淄博科恩軟啟動器報(bào)價(jià)、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，淄博科恩軟啟動器報(bào)價(jià)，根據(jù)電機(jī)的實(shí)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(hù)功能，如過流、過壓、過載保護(hù)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(shí)改變頻率；軟啟動器實(shí)際上是個(gè)調(diào)壓器，用于電機(jī)起動時(shí)，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(jià)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(jià)格也貴得多。變頻器也有軟啟動功能。淄博科恩軟啟動器報(bào)價(jià)</p><div

軟啟動器（softstarter）是一種集電機(jī)軟起動、軟停車、多種保護(hù)功能于一體的新穎電機(jī)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(jià)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(hù)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。淄博科恩軟啟動器報(bào)價(jià)</p><div

軟起動器具有軟起動、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)域的動力設(shè)備控制中具有傳統(tǒng)降壓起動器不可比擬的優(yōu)越性。三相異步電動機(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)品改善了異步電動機(jī)這兩個(gè)弱點(diǎn)，一是變頻器，二是軟啟動器。變頻器改善異步電動機(jī)的調(diào)速性能；軟起動在起動時(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，熱元件在電動機(jī)起動過程中很難避開電機(jī)的起動電流而產(chǎn)生誤動作。為避免誤動，用戶常加大熱元件的動作電流，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)。而軟起動器內(nèi)置的過載保護(hù)功能是根據(jù)起動負(fù)荷的輕重(即起動時(shí)間的長短)來選擇不同的脫扣特性曲線，以避免在起動過程中誤跳。由于它的過載保護(hù)是可編程的，軟啟動器廠家從而為用戶提供了更大的靈活性。 </p><p>在很多從業(yè)人員和非從業(yè)人員的眼中，軟啟動器行業(yè)都是夕陽產(chǎn)業(yè)。那么軟啟動器是否是夕陽西下，日落西山了呢？我們首先來看一個(gè)圖這是軟啟動器近10年來的一個(gè)搜索數(shù)據(jù)的曲線除了2015年異軍突起，其他的時(shí)間都保持著平穩(wěn)發(fā)展的趨勢，沒有說是特別的下降。即便是今年的**影響下，搜索量也是與往年相比保持個(gè)持平的狀態(tài)，可以說，低壓軟啟動器行業(yè)雖然沒有太高的提升，但是還是保持著一個(gè)平穩(wěn)發(fā)展的態(tài)勢。再來看高壓端高壓軟啟動器的發(fā)展則是肉眼可見的。從19年開始高壓軟啟動器的搜索量開始快速增長，這是夕陽產(chǎn)業(yè)該有的態(tài)勢嗎。很明顯不是，那么為什么還是很多人唱衰軟啟動器行業(yè)呢。首先，國產(chǎn)變頻器從18年開始價(jià)格大量下浮，導(dǎo)致很多人覺得軟啟動器的生存空間被壓縮了。但是這些人卻沒想到，大部分變頻器能替代的地方基本上已經(jīng)在過去已經(jīng)替代光了。剩下的一些場景*需啟動，監(jiān)測，而不需要調(diào)速，根本用不上變頻器。同時(shí)雖然變頻器價(jià)格下浮，但是價(jià)格還是遠(yuǎn)比軟啟動器貴很多?，F(xiàn)在市場上的低壓軟啟動器，種類偏多，大抵分為外置旁路軟啟動器、內(nèi)置旁路軟啟動器和在線式軟啟動器。其中外置旁路軟啟動器，把接觸器外置，啟動之后直接切旁路運(yùn)行。</p><div

我們常常聽到電氣行業(yè)生產(chǎn)的軟啟動器應(yīng)用在很多行業(yè)的生產(chǎn)中，其中有一項(xiàng)重要的原因是節(jié)能，那么軟啟動器節(jié)能在那些方面呢？電動機(jī)屬感性負(fù)載，電流滯后電壓，大多數(shù)用電器都屬此類。為了提高功率因數(shù)須用容性負(fù)載來補(bǔ)償，并電容或用同步電動機(jī)補(bǔ)償。降低電動機(jī)的激磁電流也可提高功率因數(shù)（HPS2節(jié)能功能，在輕載時(shí)降低電壓，使激磁電流降低，使COS∮提高）。節(jié)能運(yùn)行模式：輕載時(shí)降低電壓減少了激磁電流，電機(jī)電流分為有功分量和無功分量（激磁分量）提高COS∮。節(jié)能運(yùn)行模式：當(dāng)電動機(jī)負(fù)載輕時(shí)，甘肅蘭州軟起動器在選擇節(jié)能功能的狀態(tài)下，PF開關(guān)熱撥至Y位，在電流反饋的作用下，軟起動器自動降低電動機(jī)電壓。減少了電動機(jī)電流的勵(lì)磁分量。從而提高了電動機(jī)的功率因數(shù)（COS∮）。（國產(chǎn)軟起動器多無此功能）在接觸器旁路狀態(tài)下無法實(shí)現(xiàn)此功能。TPF開關(guān)提供了節(jié)能功能的兩種反應(yīng)時(shí)間；正常、慢速。節(jié)能運(yùn)行模式：自動節(jié)能運(yùn)行。（正常、慢速兩種反應(yīng)速度）空載節(jié)能40%，負(fù)載節(jié)能5%。淄博科恩軟啟動器報(bào)價(jià)</p><p

style="font-size:12px;">電動機(jī)按照運(yùn)行工況分為S1~S10十種不同的制式。對于S1工作制(連續(xù)工作制)的電機(jī)，不論是否采用軟啟動，都不適合頻繁啟動。</span><span

style="font-size:12px;">軟起動器的啟動周期是有一定限制的，即在多長時(shí)間內(nèi)允許啟動多少次。而且軟起動器是短時(shí)工作制的，不能長期運(yùn)行。</span><span style="font-size:12px;">再者，頻繁啟動對電機(jī)也不好，會減少電機(jī)的使用壽命。</span>
