軟啟動(dòng)器的優(yōu)越性能有哪些(1)軟啟動(dòng)器在起動(dòng)過程中，能控制電機(jī)電壓按線性增加，以使電機(jī)電流也線性增加，因此不會(huì)對(duì)電網(wǎng)造成沖擊，不會(huì)對(duì)配電回路造成更大的電壓降，延長(zhǎng)了電氣設(shè)備的使用壽命。并且電機(jī)起動(dòng)電流，起動(dòng)轉(zhuǎn)矩可調(diào)節(jié)，滿足了生產(chǎn)工藝的要求。(2)軟啟動(dòng)器在起動(dòng)過程當(dāng)中不受電網(wǎng)電壓波動(dòng)的影響。當(dāng)電網(wǎng)電壓出現(xiàn)波動(dòng)時(shí)，由于軟起動(dòng)器的晶閘管控制電路中引入了電流反饋，使得在整個(gè)起動(dòng)過程當(dāng)中，通過控制晶閘管的觸發(fā)角和導(dǎo)通角來保持起動(dòng)電流的恒定，使電動(dòng)機(jī)平穩(wěn)起動(dòng)，不受配電回路電壓波動(dòng)的影響。(3)應(yīng)用的范圍非常廣。通過調(diào)節(jié)軟啟動(dòng)器的電壓、電流和時(shí)間參數(shù)，可以滿足不同的起動(dòng)電流、轉(zhuǎn)矩和時(shí)間以及各種停止的要求，時(shí)間電動(dòng)機(jī)的軟起動(dòng)和軟停止。(4)對(duì)于重復(fù)短時(shí)工作制的設(shè)備，電機(jī)長(zhǎng)時(shí)間運(yùn)行在空載和低負(fù)載狀態(tài)下，短時(shí)運(yùn)行于重負(fù)載狀態(tài)下。軟啟動(dòng)器在滿足其他要求的同時(shí)，還有節(jié)能控制環(huán)節(jié)，提高空載和低負(fù)荷時(shí)的功率因素，以達(dá)到節(jié)能目的。(5)一臺(tái)軟啟動(dòng)器可以起動(dòng)多臺(tái)電動(dòng)機(jī)。尤其是對(duì)于外接法只要加上一定的輔助電路，就能實(shí)現(xiàn)用一臺(tái)軟啟動(dòng)器帶動(dòng)多臺(tái)電動(dòng)機(jī)，這樣就的減少了成本?？傊?，深入的了解生產(chǎn)工藝過程，了解對(duì)起動(dòng)和停止的要求。 </p><p> 高壓軟起動(dòng)器對(duì)信號(hào)的檢測(cè)比低壓軟起動(dòng)器要求更高。高壓軟起動(dòng)器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動(dòng)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(huì)產(chǎn)生大量的電磁干擾。所以對(duì)檢測(cè)到的信號(hào)不*要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號(hào)。軟起動(dòng)器在完成起動(dòng)過程后，要切換到旁路運(yùn)行狀態(tài)，如何平滑地切換到運(yùn)行狀態(tài)，這也是軟起動(dòng)器的一個(gè)難點(diǎn)，如何選準(zhǔn)旁路點(diǎn)非常重要。旁路點(diǎn)早了，電流沖擊非常大，即使在低壓條件下，也會(huì)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(diǎn)遲了，電機(jī)抖動(dòng)得厲害，影響負(fù)載正常工作。因此，旁路信號(hào)的硬件檢測(cè)電路必須非常精確，并且程序處理也要恰到好處。綜上所述，盡管低壓軟起動(dòng)器和高壓軟起動(dòng)器的基本原理一致，但高壓軟起動(dòng)器存在的諸多技術(shù)難題，使得在低壓軟起動(dòng)器遍地開花的情況下，高壓軟起動(dòng)器的成熟產(chǎn)品并不多見。

從長(zhǎng)期來看：變頻軟起將會(huì)成為軟起動(dòng)器（西馳分級(jí)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，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(dòng)而選用變頻器將不再會(huì)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，可以實(shí)現(xiàn)包括軟停止在內(nèi)的各種起動(dòng)功能。對(duì)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)器怎么聯(lián)系</p><p
