變頻器和軟啟動(dòng)器是兩種完全不同用途的產(chǎn)品。變頻器主要是用于需要電動(dòng)機(jī)調(diào)速的地方，因此也被稱為變頻調(diào)速器，其輸出不但改變電壓而且同時(shí)改變頻率。變頻器具備所有軟啟動(dòng)器和其他啟動(dòng)控制裝置的功能，且啟動(dòng)特性上較之其他電動(dòng)機(jī)啟動(dòng)裝置有比較大的優(yōu)勢(shì).因此完全可以用作電動(dòng)機(jī)的軟啟動(dòng)控制。但之所以目前在電動(dòng)機(jī)的啟動(dòng)控制領(lǐng)城軟啟動(dòng)器仍占據(jù)主要位置.是由于變頻器固有的一些劣勢(shì)，且短期內(nèi)很難克服.只有克服了這些劣勢(shì)之后.變頻器才有可能取代軟啟動(dòng)器。變頻器的特點(diǎn)如下。(1)啟動(dòng)轉(zhuǎn)矩大，功率因數(shù)高。因?yàn)殡妱?dòng)機(jī)的功率因數(shù)與工作頻率有關(guān)，在電動(dòng)機(jī)低速運(yùn)行時(shí)工頻電源下的功率因數(shù)遠(yuǎn)低于低頻電源下的功率因數(shù)。變頻器可以控制電動(dòng)機(jī)從低頻起步.且在整個(gè)啟動(dòng)過程中在接近額定電流的條件下始終保持比較高的功率因數(shù)和接近額定轉(zhuǎn)矩的輸出轉(zhuǎn)矩。(2)輕載或空載條件下.或啟動(dòng)期間采取減載卸載等措施時(shí).變頻器容量可以比電動(dòng)機(jī)容量小。當(dāng)然，啟動(dòng)完成后變頻器需要退出運(yùn)行。(3)啟動(dòng)電流小。變頻器一電動(dòng)機(jī)拖動(dòng)系統(tǒng)允許的啟動(dòng)時(shí)間可以很長。因?yàn)樵谶@期間，電動(dòng)機(jī)電流可以不超過電動(dòng)機(jī)額定電流，因此，不論是變頻器、電動(dòng)機(jī)還是其他元器件均沒有超常地發(fā)熱。 </p><p style="text-indent:25px">大家都知道在軟啟動(dòng)器中都會(huì)有一個(gè)R型變壓器，R型變壓器主要是采用取向性高磁導(dǎo)率硅鋼帶制成的，同時(shí)具有體積小、重量輕、效率高、漏磁小等特點(diǎn)得到了普遍的應(yīng)用。軟啟動(dòng)器在控制電路時(shí)需要使用低壓直電流，但是又不能直接使用開關(guān)電源，所以在使用時(shí)需要一種隔離電源變壓器，于是軟啟動(dòng)器就看上了R型變壓器了。軟啟動(dòng)器選擇R型變壓器也不是沒有道理的，下面來說一下使用R型變壓器的好處。 1.效率高 R型變壓器鐵芯無切割，損失小，并且使用***的材料和緊湊的結(jié)構(gòu)，可以把鐵芯與繞組之間的距離降底，這樣效率可以達(dá)到百分之90以上。 2.無噪音由于R型變壓器是使用***低損耗的材料，并且具有均勻圓形截面和連續(xù)的繞線，電阻的損耗和產(chǎn)熱都非常的低，磁致伸縮應(yīng)力很容易被吸收，因此在使用過程中不會(huì)發(fā)出噪音來。 3.漏磁小 R型變壓器的鐵芯都是繞線極勻衡，因此漏磁是非常小的，在使用過程中無需采取防范措施來防止漏磁的現(xiàn)象。 4.符合安全的標(biāo)準(zhǔn) 由于它的獨(dú)特設(shè)計(jì)，將初級(jí)與次級(jí)的骨架分開，并且具有良好的絕緣性。由于阻燃材料制成的互相分離的骨架這樣可以滿足我國的安全標(biāo)準(zhǔn)科恩電氣始終以適應(yīng)和促進(jìn)工業(yè)發(fā)展為宗旨。</p><div style="width:100%;text-align: center;"><img

我們常常聽到電氣行業(yè)生產(chǎn)的軟啟動(dòng)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(dòng)器節(jié)能在那些方面呢？電動(dòng)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(dòng)機(jī)補(bǔ)償。降低電動(dòng)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(dòng)機(jī)負(fù)載輕時(shí)，甘肅蘭州軟起動(dòng)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(dòng)器自動(dòng)降低電動(dòng)機(jī)電壓。減少了電動(dòng)機(jī)電流的勵(lì)磁分量。從而提高了電動(dòng)機(jī)的功率因數(shù)（COS∮）。（國產(chǎn)軟起動(dòng)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(dòng)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%。以客戶至上為理念，為客戶提供咨詢服務(wù)。淄博科恩軟啟動(dòng)器選購</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。淄博科恩軟啟動(dòng)器生產(chǎn)商</p><p
