id="3v7ajfx" class="box"><p><p style="text-indent:25px">電機軟啟動器的主接線有三種方法主要是在線型、旁路型、內(nèi)置旁路型。 1.在線型：一切軟發(fā)動器的控制器都有電動機過載保護，淄博科恩軟啟動器訂購，當軟啟動器在線運行時對電機進行過載保護，不要加裝熱過載繼電器。由于經(jīng)過可控硅后的電流諧波電流非常大，所以不能加裝電子式熱過載繼電器，否則會使系統(tǒng)不能正常的工作。 2，淄博科恩軟啟動器訂購.旁路型：對于軟啟動器上口的接觸器的作用和在線運行方式下作用相同的情況下不能再重復。這邊注意的熱繼電器，把它安方在旁路接觸器的下口，不通電流，尤其是電子熱繼電器，由于經(jīng)過軟啟動器后電流諧波很大能干擾電子熱繼電器誤動作而使電機停車。 3，淄博科恩軟啟動器訂購.內(nèi)置旁路型：它的主接線和在線型的大致相同，它的主要優(yōu)點是可控硅的短時工作沒必要安裝快速熔斷器。我公司將以優(yōu)良的產(chǎn)品，周到的服務與尊敬的用戶攜手并進！淄博科恩軟啟動器訂購</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淄博科恩軟啟動器訂購,科恩軟啟動器" src="http://tyunfile.71360.com/UpLoadFile/2019/4/13/14/636907616797936241_keendianqi_9481264.jpg"></div><p> 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一起歸并為傳統(tǒng)的起動技術。隨著變頻器價格的逐漸下降，可靠性的進一步提高，也隨著技術人員水平的提高，**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，應在起動完成后使變頻器脫電，使電動機直掛電網(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。淄博科恩軟啟動器訂購我公司生產(chǎn)的產(chǎn)品、設備用途非常多。</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)境條件下運行。注意檢查軟起動器周圍是否有妨礙其通風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?，F(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。平時注意觀察風機的運行情況一旦發(fā)現(xiàn)風機轉(zhuǎn)速慢或異常應及時修理如油垢、積塵加潤滑油更換損壞或變質(zhì)的電容器。對損壞的風機要及時更換。如果在沒有風機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)境較潮濕或易結露應經(jīng)常用紅外燈泡或電吹風烘干驅(qū)除潮氣以避免漏電或短路的發(fā)生。 </p><p> 軟啟動的好處1．降低電動機的起動電流，減少配電容量，避免增容投資；2．減少起動應力，延長電動機及相關設備的使用壽命；3．平穩(wěn)的起動和軟停車避免了傳統(tǒng)起動設備的喘振問題、水錘效應；4．多種起動模式及寬范圍的電流、電壓等設定，可適應多種負載情況，改善工藝；5．完善可靠的保護功能，更有效的保護電動機及相關設備的安全；軟啟動器的工作原理軟起動主要由串接于電源與被控電動機之間三對反并聯(lián)晶閘管調(diào)壓電路構成。現(xiàn)代軟啟動器基本上都采用了電力電子技術和微機控制技術，以單片微機作為**控制器控制來完成測量及各種控制算法。因此，山東濟寧軟啟動器具備了很強的功能和靈活性。整個起動過程是數(shù)字化程序軟件控制下自動進行。利用三對晶閘管的電子開關特性，通過MCU或單片機控制其觸發(fā)脈沖的遲早來改變觸發(fā)角的大小。而改變觸發(fā)導通角的大小，又改變了晶閘管的導通時間，較終改變定子繞組的三相電壓的大小。主要元件1、晶閘管：每相一對反并聯(lián)晶閘管，這是主要的功率元件，也是軟啟動器的主要成本之一，國內(nèi)做反并聯(lián)晶閘管的廠家有很多，從便宜的到貴的都有，質(zhì)量更是參差不齊。2、控制主板：基本上每個廠家都有自己開發(fā)的主板，市場上也有很多通用主板。科恩電氣愿和各界朋友真誠合作一同開拓。</p><div

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、合理的防護措施是十分必要的，防塵措施得當對保證控制柜正常工作非常重要?？傮w要求控制柜整體應該密封，應該通過專門設計的進風口、出風口進行通風;控制柜頂部應該有防護網(wǎng)和防護頂蓋出風口；控制柜底部應該有底板和進風口、進線孔，并且安裝防塵網(wǎng)。粉塵場所對控制柜的設計要求：(1)控制柜的風道要設計合理，排風通暢，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)面排風方式，出風口必須安裝防護網(wǎng)。(3)控制柜頂部出風口上面要安裝防護頂蓋，防止雜物直接落入;防護頂蓋高度要合理，不影響排風。防護頂蓋的側(cè)面出風口要安裝防護網(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行一定的密封處理，防止粉塵進入。(5)一定要確保控制柜頂部的軸流風機旋轉(zhuǎn)方向正確，向外抽風。如果風機安裝在控制柜頂部的外部，必須確保防護頂蓋與風機之間有足夠的高度；如果風機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，防止風機脫落造成柜內(nèi)元件和設備的損壞。建議在風機和柜體之間加裝塑料或者橡膠減振墊圈。科恩電氣重信譽、守合同，嚴把產(chǎn)品質(zhì)量關，熱誠歡迎廣大用戶前來咨詢考察，洽談業(yè)務！淄博科恩軟啟動器訂購</p><p

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，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。淄博科恩軟啟動器訂購</p><p
