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，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)，淄博科恩軟啟動(dòng)器銷(xiāo)售公司，通過(guò)改變電機(jī)工作電源頻率方式來(lái)控制交流電動(dòng)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）、制動(dòng)單元、驅(qū)動(dòng)單元、檢測(cè)單元微處理單元等組成。變頻器靠?jī)?nèi)部IGBT的開(kāi)斷來(lái)調(diào)整輸出電源的電壓和頻率，根據(jù)電機(jī)的實(shí)際需要來(lái)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(guò)流、過(guò)壓、過(guò)載保護(hù)等等。隨著工業(yè)自動(dòng)化程度的不斷提高，變頻器也得到了非常的應(yīng)用。軟啟動(dòng)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(dòng)器實(shí)際上是個(gè)調(diào)壓器，用于電機(jī)起動(dòng)時(shí)，輸出只改變電壓并沒(méi)有改變頻率。變頻器具備所有軟起動(dòng)器功能，但它的價(jià)格比軟啟動(dòng)器貴得多，結(jié)構(gòu)也復(fù)雜得多。軟啟動(dòng)器只是改變電源電壓，淄博科恩軟啟動(dòng)器銷(xiāo)售公司，相當(dāng)于降壓起動(dòng)器，淄博科恩軟啟動(dòng)器銷(xiāo)售公司。變頻器要比軟啟動(dòng)器復(fù)雜得多，價(jià)格也貴得多。變頻器也有軟啟動(dòng)功能。淄博科恩軟啟動(dòng)器銷(xiāo)售公司</p><div

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(wú)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(guò)載保護(hù)功能一般電機(jī)的過(guò)載保護(hù)是通過(guò)熱元件來(lái)實(shí)現(xiàn)的，熱元件在電動(dòng)機(jī)起動(dòng)過(guò)程中很難避開(kāi)電機(jī)的起動(dòng)電流而產(chǎn)生誤動(dòng)作。為避免誤動(dòng)，用戶常加大熱元件的動(dòng)作電流，因而使得過(guò)載保護(hù)的靈敏度不夠，使過(guò)載保護(hù)形同虛設(shè)。而軟起動(dòng)器內(nèi)置的過(guò)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(zhǎng)短)來(lái)選擇不同的脫扣特性曲線，以避免在起動(dòng)過(guò)程中誤跳。由于它的過(guò)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。 </p><p> 軟啟動(dòng)器1.無(wú)沖擊電流，軟啟動(dòng)器在啟動(dòng)電動(dòng)機(jī)時(shí)，通過(guò)逐漸增大晶閘管導(dǎo)通角，使電動(dòng)機(jī)啟動(dòng)電流從零線性上升至設(shè)定值。2.恒流啟動(dòng)，軟啟動(dòng)器可以引人電流閉環(huán)控制，使電動(dòng)機(jī)在啟動(dòng)過(guò)程中保持恒流，確保電動(dòng)機(jī)平穩(wěn)啟動(dòng)。3.根據(jù)負(fù)載情況及電網(wǎng)繼電保護(hù)特性選擇，可自由地?zé)o級(jí)調(diào)整至比較好的啟動(dòng)電流。4.電動(dòng)機(jī)停機(jī)時(shí)，傳統(tǒng)的控制方式都是通過(guò)瞬間停電完成的。但有許多應(yīng)用場(chǎng)合，不允許電動(dòng)機(jī)瞬問(wèn)關(guān)機(jī)。例如:高層建筑、大樓的水泵系統(tǒng)，如果瞬間停機(jī)，會(huì)產(chǎn)生巨大的“水錘”效應(yīng)，使軟起甚至水泵損壞。為減少和防止“水錘”效應(yīng)，需要電動(dòng)機(jī)逐步停機(jī)，即軟停車(chē)，采用軟啟動(dòng)器能滿足這一要求。在泵站中，應(yīng)用軟停車(chē)技術(shù)可避免泵站的“拍門(mén)”損壞，減少維修費(fèi)用和維修工作量。5.軟啟動(dòng)器輕載節(jié)能?；\型異步電動(dòng)機(jī)是感性負(fù)載，在運(yùn)行中，定子線圈繞組中的電流滯后于電壓。如電動(dòng)機(jī)工作電壓不變，處于輕載時(shí)。功率因數(shù)低;處于重載時(shí)，功率因數(shù)高。在輕載時(shí)，軟啟動(dòng)器通過(guò)降低電動(dòng)機(jī)端電壓，提高功率因數(shù)，減少電動(dòng)機(jī)的鋼耗、鐵耗，達(dá)到輕載節(jié)能的目的;負(fù)載重時(shí)，則提高電動(dòng)機(jī)端電壓，確保電動(dòng)機(jī)正常運(yùn)行。</p><div
