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*要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，淄博科恩軟啟動器代理，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(jī)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，淄博科恩軟啟動器代理，并且程序處理也要恰到好處，淄博科恩軟啟動器代理。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。淄博科恩軟啟動器代理</p><div

從長期來看：變頻軟起將會成為軟起動器（西馳分級變頻軟起動器）的主流。各種形式的降壓軟起動將與星三角起動等技術(shù)一起歸并為傳統(tǒng)的起動技術(shù)。隨著變頻器價格的逐漸下降，可靠性的進(jìn)一步提高，也隨著技術(shù)人員水平的提高，**為軟起動而選用變頻器將不再會被人們認(rèn)為是一種。變頻軟起動勝出的根本原因是：它可以在限流（起動電流不超過電機(jī)額定電流值）的同時獲得大的起動轉(zhuǎn)矩，可以實現(xiàn)包括軟停止在內(nèi)的各種起動功能。對于**為軟起動而制作的變頻器而言，應(yīng)在起動完成后使變頻器脫電，使電動機(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。淄博科恩軟啟動器代理</p><div

style="text-indent:25px">軟啟動是指電機(jī)的電壓由零慢慢上升到額定電壓，這樣電機(jī)在啟動的過程中啟動電流，由過去的過載沖擊不可控電流變成了可控制的電流，并且可以根據(jù)需要來對電機(jī)啟動器進(jìn)行電流的大小調(diào)整。如果直接啟動電機(jī)軟啟動器對軟啟動器有什么樣的危害呢？ 1.會引起電網(wǎng)電壓的波動交流電動機(jī)在全壓下直接啟動，起動電流會達(dá)到額定電流的4到7倍，如果電機(jī)的容量相對來說比較大時，啟動電流會引起電網(wǎng)電壓的急劇下降，同時還會影響電網(wǎng)和其他設(shè)備的正常運行。 2.對電網(wǎng)的影響對于電網(wǎng)的影響會表現(xiàn)在兩個方面（1）超大型的電機(jī)直接啟動，大電流對電網(wǎng)的沖擊相當(dāng)于三相短路對電網(wǎng)的沖擊，這時會常常應(yīng)發(fā)發(fā)動機(jī)的振蕩，使電網(wǎng)失去穩(wěn)定。（2）起動電流中含有大量的高次諧波，會與電網(wǎng)電路參數(shù)引起高頻諧振，造成繼電保護(hù)誤動作、自動控制失靈等故障。 3.傷害電機(jī)絕緣（1）大電流所產(chǎn)生的焦耳熱反復(fù)作用于導(dǎo)線外絕緣，使絕緣加速老化、壽命降低。（2）大電流產(chǎn)生的機(jī)械力使導(dǎo)線相互摩擦，降低絕緣壽命。（3）高壓開關(guān)合閘時觸頭的抖動現(xiàn)象會在電機(jī)定子繞組上產(chǎn)生操作過電壓，有時會達(dá)到外加電壓的5倍以上，這樣高的過電壓會對電機(jī)絕緣造成極大。</p><p> 電機(jī)軟啟動器是一種集軟啟動、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，也能使用軟啟動器來進(jìn)行代替。節(jié)約了成本的同時，也使不必要的浪費得到控制。那么是哪些方面造就了電機(jī)軟啟動器的高性價比呢?1、啟動方式：根據(jù)負(fù)載特點選擇不同的啟動模式及參數(shù)設(shè)置，可很大程度的使電動機(jī)實現(xiàn)比較好的啟動效果，三種啟動方式：電壓斜坡啟動——可得到比較大的輸出扭矩;限流啟動——可有效地限制啟動電流;點動——可實現(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小時高溫循環(huán)試驗和振動試驗，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)軟啟動器擁有便捷直觀的操作顯示鍵盤，可根據(jù)不同負(fù)載。

變頻器和軟啟動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改變頻率。變頻器具備所有軟啟動器和其他啟動控制裝置的功能，且啟動特性上較之其他電動機(jī)啟動裝置有比較大的優(yōu)勢.因此完全可以用作電動機(jī)的軟啟動控制。但之所以目前在電動機(jī)的啟動控制領(lǐng)城軟啟動器仍占據(jù)主要位置.是由于變頻器固有的一些劣勢，且短期內(nèi)很難克服.只有克服了這些劣勢之后.變頻器才有可能取代軟啟動器。變頻器的特點如下。(1)啟動轉(zhuǎn)矩大，功率因數(shù)高。因為電動機(jī)的功率因數(shù)與工作頻率有關(guān)，在電動機(jī)低速運行時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機(jī)從低頻起步.且在整個啟動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.或啟動期間采取減載卸載等措施時.變頻器容量可以比電動機(jī)容量小。當(dāng)然，啟動完成后變頻器需要退出運行。(3)啟動電流小。變頻器一電動機(jī)拖動系統(tǒng)允許的啟動時間可以很長。因為在這期間，電動機(jī)電流可以不超過電動機(jī)額定電流，因此，不論是變頻器、電動機(jī)還是其他元器件均沒有超常地發(fā)熱。淄博科恩軟啟動器代理</p><p
