從長期來看：變頻軟起將會成為軟起動(dòng)器（西馳分級變頻軟起動(dòng)器）的主流。各種形式的降壓軟起動(dòng)將與星三角起動(dòng)等技術(shù)一起歸并為傳統(tǒng)的起動(dòng)技術(shù)。隨著變頻器價(jià)格的逐漸下降，淄博科恩軟啟動(dòng)器廠家直供，可靠性的進(jìn)一步提高，淄博科恩軟啟動(dòng)器廠家直供，也隨著技術(shù)人員水平的提高，**為軟起動(dòng)而選用變頻器將不再會被人們認(rèn)為是一種。變頻軟起動(dòng)勝出的根本原因是：它可以在限流（起動(dòng)電流不超過電機(jī)額定電流值）的同時(shí)獲得大的起動(dòng)轉(zhuǎn)矩，淄博科恩軟啟動(dòng)器廠家直供，可以實(shí)現(xiàn)包括軟停止在內(nèi)的各種起動(dòng)功能。對于**為軟起動(dòng)而制作的變頻器而言，應(yīng)在起動(dòng)完成后使變頻器脫電，使電動(dòng)機(jī)直掛電網(wǎng)。這樣做的目的是節(jié)能，消除無謂的損耗。這種操作應(yīng)該在安全的不引起電流沖擊的條件下完成，或者叫做軟切換。軟切換的可能步驟是“先脫（電）后掛（網(wǎng)）”或“先掛后脫”，軟切換應(yīng)該在基本上不增加硬件（例如軟切換電抗器）的條件下主要靠軟件完成。淄博科恩軟啟動(dòng)器廠家直供</p><div

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)，通過改變電機(jī)工作電源頻率方式來控制交流電動(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(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(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，相當(dāng)于降壓起動(dòng)器。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。 </p><p> 電機(jī)軟啟動(dòng)器是一種集軟啟動(dòng)、軟停車、輕載節(jié)能和多功能保護(hù)于一體的新穎電機(jī)控制裝置，的應(yīng)用于風(fēng)機(jī)、水泵、輸送類及壓縮機(jī)等負(fù)載，是傳統(tǒng)的星/三角轉(zhuǎn)換、自耦降壓磁控降壓等降壓設(shè)備的理想換代產(chǎn)品。在某些變頻器大材小用的場合，也能使用軟啟動(dòng)器來進(jìn)行代替。節(jié)約了成本的同時(shí)，也使不必要的浪費(fèi)得到控制。那么是哪些方面造就了電機(jī)軟啟動(dòng)器的高性價(jià)比呢?1、啟動(dòng)方式：根據(jù)負(fù)載特點(diǎn)選擇不同的啟動(dòng)模式及參數(shù)設(shè)置，可很大程度的使電動(dòng)機(jī)實(shí)現(xiàn)比較好的啟動(dòng)效果，三種啟動(dòng)方式：電壓斜坡啟動(dòng)——可得到比較大的輸出扭矩;限流啟動(dòng)——可有效地限制啟動(dòng)電流;點(diǎn)動(dòng)——可實(shí)現(xiàn)試車調(diào)試功能。2、高技術(shù)性能：由于采用了高性能微處理器及強(qiáng)大的軟件支持功能使控制電路得以簡化，無需對電路參數(shù)進(jìn)行調(diào)整，即可獲得一致、準(zhǔn)確及快速的執(zhí)行速度;**度抗干擾功能。3、高可靠性：電機(jī)軟啟動(dòng)器所有電器元件均經(jīng)過嚴(yán)格的篩選，其主控板還須經(jīng)過72小時(shí)高溫循環(huán)試驗(yàn)和振動(dòng)試驗(yàn)，從而保證了出廠產(chǎn)品的高可靠性。4、優(yōu)化的結(jié)構(gòu)：獨(dú)特緊湊的模塊化結(jié)構(gòu)及上進(jìn)線下出線的連接方式，非常方便用戶的集成、成套。5、鍵盤設(shè)置功能：電機(jī)軟啟動(dòng)器擁有便捷直觀的操作顯示鍵盤，可根據(jù)不同負(fù)載。

軟起動(dòng)器主回路采用晶閘管,通過逐步改變晶閘管的導(dǎo)通角來抬升電壓,完成起動(dòng)過程,這是軟起動(dòng)器的基本原理。目前在低壓軟起動(dòng)器市場,產(chǎn)品繁多,但是高壓軟起動(dòng)器產(chǎn)品還是比較少。高壓軟起動(dòng)器與低壓軟起動(dòng)器基本原理一樣，但是高壓軟起動(dòng)器與低壓軟起動(dòng)器相比,有些地方存在著其特殊性：1.高壓軟起動(dòng)器在高壓環(huán)境下工作,各種電氣元器件的絕緣性能一定要好,電子芯片的抗干擾能力要強(qiáng)。高壓軟起動(dòng)器組成電氣柜時(shí),電氣元器件的布局以及與高壓軟起動(dòng)器與其它電氣設(shè)備的連接也是非常重要的。2.高壓軟起動(dòng)器必須有一個(gè)高性能的控制,能對信號進(jìn)行及時(shí)和快速地處理。因此這個(gè)控制一般采用高性能的DSP芯片,而不是低壓軟起動(dòng)器的普通單片機(jī)芯。低壓軟起動(dòng)器主回路由三組反并聯(lián)的晶閘管組成。而在高壓軟起動(dòng)器中,由于目前單只高壓晶閘管的耐壓能力不夠,所以必須由多個(gè)高壓晶閘管串聯(lián)進(jìn)行分壓。但是每個(gè)晶閘管的性能參數(shù)沒有完全一致。晶閘管參數(shù)的不一致，會導(dǎo)致晶閘管開通時(shí)間不一致，從而導(dǎo)致晶閘管的損壞。因此在晶閘管的選配上,必須保證每一相的晶閘管參數(shù)盡可能地一致，并且每一相晶閘管的RC濾波電路的元件參數(shù)盡可能一致。3．高壓軟起動(dòng)器的工作環(huán)境容易受到各種電磁干擾。淄博科恩軟啟動(dòng)器廠家直供</p><p

現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號的軟啟動(dòng)器來選用軟啟動(dòng)器軟啟動(dòng)器選型：目前市場上常見的軟啟動(dòng)器有旁路型軟啟動(dòng)器、無旁路型軟啟動(dòng)器、節(jié)能型軟啟動(dòng)器等。下面我們來一一講它們的功能：旁路型軟啟動(dòng)器：在電動(dòng)機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí)，用旁路接觸器取代已完成任務(wù)的軟啟動(dòng)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(dòng)器去啟動(dòng)多臺電動(dòng)機(jī)。無旁路型軟啟動(dòng)器：晶閘管處于全導(dǎo)通狀態(tài)，電動(dòng)機(jī)工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時(shí)重復(fù)工作的電動(dòng)機(jī)。節(jié)能型軟啟動(dòng)器：當(dāng)電動(dòng)機(jī)負(fù)荷較輕時(shí)，軟啟動(dòng)器自動(dòng)降低施加于電動(dòng)機(jī)定子上的電壓，減少電動(dòng)機(jī)電流勵(lì)磁分量，提高電動(dòng)機(jī)功率因數(shù)。軟啟動(dòng)器如何選規(guī)格?根據(jù)電動(dòng)機(jī)的標(biāo)稱功率，電流負(fù)載性質(zhì)選擇啟動(dòng)器，一般軟啟動(dòng)器容量稍大于電動(dòng)機(jī)工作電流，還應(yīng)考慮保護(hù)作用是否完備，例如：缺相保護(hù)、短路保護(hù)、過載保護(hù)、逆序保護(hù)、過壓保護(hù)、欠壓保護(hù)等。淄博科恩軟啟動(dòng)器廠家直供</p><p
