style="text-indent:25px">軟啟動是指電機的電壓由零慢慢上升到額定電壓，這樣電機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，淄博科恩軟啟動器推薦，并且可以根據(jù)需要來對電機啟動器進行電流的大小調(diào)整，淄博科恩軟啟動器推薦。如果直接啟動電機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在全壓下直接啟動，起動電流會達到額定電流的4到7倍，如果電機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，造成繼電保護誤動作、自動控制失靈等故障。 3.傷害電機絕緣（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，淄博科恩軟啟動器推薦、壽命降低。（2）大電流產(chǎn)生的機械力使導(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)象會在電機定子繞組上產(chǎn)生操作過電壓，有時會達到外加電壓的5倍以上，這樣高的過電壓會對電機絕緣造成極大。淄博科恩軟啟動器推薦</p><div

軟啟動器以體積小,轉(zhuǎn)矩可以調(diào)節(jié)、啟動平穩(wěn)、沖擊小并具有軟停機功能等優(yōu)點得到了越來越多的應(yīng)用,大有取代傳統(tǒng)的自耦減壓、星三角變換降壓啟動的趨勢。由于軟啟動器是近年來新發(fā)展起來的啟動設(shè)備,缺少相應(yīng)的設(shè)計及使用經(jīng)驗等籠形異步電動機是應(yīng)用**的用電設(shè)備。由于電動機直接啟動時的沖擊電流很大，特別是大容量電動機直接啟動會對電網(wǎng)及其他負載造成干擾甚至危害電網(wǎng)的安全運行，所以按不同工況，采用許多種減壓啟動方式。早期的方式有串聯(lián)電抗或電阻、串聯(lián)自耦變壓器星三角轉(zhuǎn)換等。從20世紀(jì)70年代起，工程上開始推廣利用晶閘管交流調(diào)壓技術(shù)制作的軟啟動器。這種軟啟動器是集電動機軟啟動、軟停車、輕載節(jié)能和多種保護功能于一體的新穎電動機控制裝置，國外稱為softstarter。軟啟動器的構(gòu)成主要是串接于電源與被控電動機之間的三相反并聯(lián)晶閘管及其電子控制電路。軟啟動器的工作原理是，控制電路運用不同的方法，控制三相反并聯(lián)晶閘管的導(dǎo)通角，使電動機輸入電壓從零以預(yù)設(shè)的函數(shù)關(guān)系逐漸上升，直至啟動結(jié)束，賦予電動機全電壓，實現(xiàn)軟啟動。在軟啟動過程中，電動機啟動轉(zhuǎn)矩逐漸增加，轉(zhuǎn)速也逐漸增加。在上述基礎(chǔ)上，把功率因數(shù)控制技術(shù)結(jié)合進去。淄博科恩軟啟動器找哪家</p><div

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啟動裝置有比較大的優(yōu)勢.因此完全可以用作電動機的軟啟動控制。但之所以目前在電動機的啟動控制領(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。因為電動機的功率因數(shù)與工作頻率有關(guān)，在電動機低速運行時工頻電源下的功率因數(shù)遠低于低頻電源下的功率因數(shù)。變頻器可以控制電動機從低頻起步.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，電動機電流可以不超過電動機額定電流，因此，不論是變頻器、電動機還是其他元器件均沒有超常地發(fā)熱。 </p><p> 有電機有負載，就需要使用到電機軟啟動器，我們知道，電機直接啟動停止會給電網(wǎng)電壓帶來很大沖擊，對我們電機本身也會帶來很大傷害，嚴(yán)重縮短使用壽命，甚至?xí)陔妷弘娏鬟^大時，燒毀電機。這時候，選擇一款合適的電機軟啟動器就非常重要了。那么，你知道電機軟啟動器怎么選擇嗎？一般來說，負載電機的功率達到，我們就建議使用軟啟動器來進行電機起停、保護工作。（這里家庭電器不列在內(nèi)）常見的風(fēng)機、水泵這種類型的負載，屬于輕型負載，選擇輕載軟起動器，功率也可以一比一選擇，如：15KW的風(fēng)機，就可以選擇15KW的Mg3軟啟動器和Mg6軟啟動器。破碎機、球磨機、皮帶機這些，則屬于重型負載，需要選擇重載軟起動器，而且要根據(jù)現(xiàn)場環(huán)境來選擇放大一檔到兩檔。如：110KW的破碎機，就可以選擇132KW的FC1000軟起動器。礦用軟啟動器，則根據(jù)井下和井上的使用環(huán)境，區(qū)分選擇，井下是需要防爆型軟啟動器的，井上則是通用型軟啟動器的。高壓軟啟動器，在選擇時，要看電網(wǎng)電壓，如果電網(wǎng)電壓是10KV，我們就需要選擇10KV的高壓軟啟動器，而不能為省成本選擇6KV，電壓等級不對，會對安全生產(chǎn)帶來很大，可能發(fā)生的危險。
