軟起動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,完成起動過程,這是軟起動器的基本原理。目前在低壓軟起動器市場,產(chǎn)品繁多,但是高壓軟起動器產(chǎn)品還是比較少。高壓軟起動器與低壓軟起動器基本原理一樣，但是高壓軟起動器與低壓軟起動器相比,有些地方存在著其特殊性：1.高壓軟起動器在高壓環(huán)境下工作,各種電氣元器件的絕緣性能一定要好，淄博科恩軟啟動器怎么聯(lián)系，淄博科恩軟啟動器怎么聯(lián)系,電子芯片的抗干擾能力要強(qiáng)。高壓軟起動器組成電氣柜時,電氣元器件的布局以及與高壓軟起動器與其它電氣設(shè)備的連接也是非常重要的。2.高壓軟起動器必須有一個高性能的控制,能對信號進(jìn)行及時和快速地處理。因此這個控制一般采用高性能的DSP芯片,而不是低壓軟起動器的普通單片機(jī)芯。低壓軟起動器主回路由三組反并聯(lián)的晶閘管組成。而在高壓軟起動器中,由于目前單只高壓晶閘管的耐壓能力不夠,所以必須由多個高壓晶閘管串聯(lián)進(jìn)行分壓。但是每個晶閘管的性能參數(shù)沒有完全一致。晶閘管參數(shù)的不一致，淄博科恩軟啟動器怎么聯(lián)系，會導(dǎo)致晶閘管開通時間不一致，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．高壓軟起動器的工作環(huán)境容易受到各種電磁干擾。淄博科恩軟啟動器怎么聯(lián)系</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(jī)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(jī)是應(yīng)用**的用電設(shè)備。由于電動機(jī)直接啟動時的沖擊電流很大，特別是大容量電動機(jī)直接啟動會對電網(wǎng)及其他負(fù)載造成干擾甚至危害電網(wǎng)的安全運(yùn)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(jī)軟啟動、軟停車、輕載節(jié)能和多種保護(hù)功能于一體的新穎電動機(jī)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(jī)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(yùn)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(jī)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(jī)全電壓，實現(xiàn)軟啟動。在軟啟動過程中，電動機(jī)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(jìn)去。淄博科恩軟啟動器怎么聯(lián)系</p><div

軟起動器的日常維修與檢查平時注意檢查軟起動器的環(huán)境條件防止在超過其允許的環(huán)境條件下運(yùn)行。注意檢查軟起動器周圍是否有妨礙其通風(fēng)散熱的物體確保軟起動器四周有足夠的空間大于150mm定期檢查配電線端子是否松動柜內(nèi)元器件有否過熱、變色、焦臭味等異常現(xiàn)象。定期清掃灰塵以免影響散熱，防止晶閘管因溫升過高而損壞同時也可避免因積塵引起的漏電和短路。清掃灰塵可用干燥的毛刷進(jìn)行也可用于皮老虎吹和吸塵器吸。對于大塊污垢可用絕緣棒去除。若有條件可用。平時注意觀察風(fēng)機(jī)的運(yùn)行情況一旦發(fā)現(xiàn)風(fēng)機(jī)轉(zhuǎn)速慢或異常應(yīng)及時修理如油垢、積塵加潤滑油更換損壞或變質(zhì)的電容器。對損壞的風(fēng)機(jī)要及時更換。如果在沒有風(fēng)機(jī)的情況下使用軟起動器將會損壞晶閘管。如果軟起動器使用環(huán)境較潮濕或易結(jié)露應(yīng)經(jīng)常用紅外燈泡或電吹風(fēng)烘干驅(qū)除潮氣以避免漏電或短路的發(fā)生。

電機(jī)保護(hù)的發(fā)展現(xiàn)狀？目前電機(jī)保護(hù)器已由過去的機(jī)械式發(fā)展為電子式和智能型，可直接顯示電機(jī)的電流、電壓、溫度等參數(shù)，靈敏度高，可靠性高，功能多，調(diào)試方便，保護(hù)動作后故障種類一目了然，既減少了電機(jī)的損壞，又極大方便了故障的判斷，有利于生產(chǎn)現(xiàn)場的故障處理和縮短恢復(fù)生產(chǎn)時間。另外，利用電機(jī)氣隙磁場進(jìn)行電機(jī)偏心檢測技術(shù)，使電機(jī)磨損狀態(tài)在線監(jiān)測成為可能，通過曲線顯示電機(jī)偏心程度的變化趨勢，可早期發(fā)現(xiàn)軸承磨損和走內(nèi)圓、走外圓等故障，做到早發(fā)現(xiàn)，早處理，避免掃膛發(fā)生。3．保護(hù)器選擇的原則？合理選用電機(jī)保護(hù)裝置，實現(xiàn)既能充分發(fā)揮電機(jī)的過載能力，又能免于損壞，從而提高電力拖動系統(tǒng)的可靠性和生產(chǎn)的連續(xù)性。具體的功能選擇應(yīng)綜合考慮電機(jī)的本身的價值、負(fù)載類型、使用環(huán)境、電機(jī)主體設(shè)備的重要程度、電機(jī)退出運(yùn)行是否對生產(chǎn)系統(tǒng)造成嚴(yán)重影響等因素，力爭做到經(jīng)濟(jì)合理。

在多粉塵場所，特別是多金屬粉塵、絮狀物的場所使用控制柜時，采取正確、合理的防護(hù)措施是十分必要的，防塵措施得當(dāng)對保證控制柜正常工作非常重要。總體要求控制柜整體應(yīng)該密封，應(yīng)該通過專門設(shè)計的進(jìn)風(fēng)口、出風(fēng)口進(jìn)行通風(fēng);控制柜頂部應(yīng)該有防護(hù)網(wǎng)和防護(hù)頂蓋出風(fēng)口；控制柜底部應(yīng)該有底板和進(jìn)風(fēng)口、進(jìn)線孔，并且安裝防塵網(wǎng)。粉塵場所對控制柜的設(shè)計要求：(1)控制柜的風(fēng)道要設(shè)計合理，排風(fēng)通暢，避免在柜內(nèi)形成渦流，在固定的位置形成灰塵堆積。(2)如果采用控制柜頂部側(cè)面排風(fēng)方式，出風(fēng)口必須安裝防護(hù)網(wǎng)。(3)控制柜頂部出風(fēng)口上面要安裝防護(hù)頂蓋，防止雜物直接落入;防護(hù)頂蓋高度要合理，不影響排風(fēng)。防護(hù)頂蓋的側(cè)面出風(fēng)口要安裝防護(hù)網(wǎng)，防止絮狀雜物直接落入。(4)控制柜的前、后門和其他接縫處，要采用密封墊片或者密封膠進(jìn)行一定的密封處理，防止粉塵進(jìn)入。(5)一定要確?？刂乒耥敳康妮S流風(fēng)機(jī)旋轉(zhuǎn)方向正確，向外抽風(fēng)。如果風(fēng)機(jī)安裝在控制柜頂部的外部，必須確保防護(hù)頂蓋與風(fēng)機(jī)之間有足夠的高度；如果風(fēng)機(jī)安裝在控制柜頂部的內(nèi)部，安裝所需螺釘必須采用止逆彈件，防止風(fēng)機(jī)脫落造成柜內(nèi)元件和設(shè)備的損壞。建議在風(fēng)機(jī)和柜體之間加裝塑料或者橡膠減振墊圈。淄博科恩軟啟動器怎么聯(lián)系</p><p

style="text-indent:25px">在電動機(jī)啟動時，降低加到電動機(jī)定子繞組的電壓可以減小電動機(jī)的啟動電流。一般降壓啟動是指電動機(jī)在啟動過程中加在電動機(jī)定子繞組的電壓變化是瞬間突變的，主要有“Y—△”降壓啟動和自藕變壓器降壓啟動等;而軟啟動是使用調(diào)壓裝置在規(guī)定的啟動時間內(nèi)，自動地將啟動電壓連續(xù)、平滑地上升，直到達(dá)到額定電壓。若采用一般降壓啟動，則啟動過程是跳躍的、不平滑的，所以又叫作硬啟動，對生產(chǎn)工藝要求穩(wěn)啟動的場合不宜采用。而軟啟動從初始電壓開始電壓連續(xù)平穩(wěn)地增大，在啟動過程中電動機(jī)的轉(zhuǎn)矩是平滑的而不是跳躍的，啟動過程是平穩(wěn)的，所以叫軟啟動。軟啟動器工作原理是當(dāng)電機(jī)啟動時，由電子電路控制晶閘管的導(dǎo)通角使電機(jī)的端電壓以設(shè)定的速度逐漸升高，一直升到全電壓，使電機(jī)實現(xiàn)無沖擊啟動到控制電動機(jī)軟啟動的過程。當(dāng)電動機(jī)啟動完成并達(dá)到額定電壓時，使三相旁路接觸器閉合，電動機(jī)直接投入電網(wǎng)運(yùn)行。如果是輕載，則在正常運(yùn)行時，也保持所需的較低端電壓，使電機(jī)的功率因數(shù)升高，效率增大。在電機(jī)停機(jī)時，也通過控制晶閘管的導(dǎo)通角，使電機(jī)端電壓慢慢降低至0，從而實現(xiàn)軟停機(jī)。淄博科恩軟啟動器怎么聯(lián)系</p><p
