軟啟動器以體積小，淄博科恩軟啟動器生產(chǎn)商，淄博科恩軟啟動器生產(chǎn)商,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)展起來的啟動設備,缺少相應的設計及使用經(jīng)驗等籠形異步電動機是應用**的用電設備。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)晶閘管的導通角，使電動機輸入電壓從零以預設的函數(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，淄博科恩軟啟動器生產(chǎn)商。在上述基礎上，把功率因數(shù)控制技術(shù)結(jié)合進去。淄博科恩軟啟動器生產(chǎn)商</p><div

軟啟動器1.無沖擊電流，軟啟動器在啟動電動機時，通過逐漸增大晶閘管導通角，使電動機啟動電流從零線性上升至設定值。2.恒流啟動，軟啟動器可以引人電流閉環(huán)控制，使電動機在啟動過程中保持恒流，確保電動機平穩(wěn)啟動。3.根據(jù)負載情況及電網(wǎng)繼電保護特性選擇，可自由地無級調(diào)整至比較好的啟動電流。4.電動機停機時，傳統(tǒng)的控制方式都是通過瞬間停電完成的。但有許多應用場合，不允許電動機瞬問關(guān)機。例如:高層建筑、大樓的水泵系統(tǒng)，如果瞬間停機，會產(chǎn)生巨大的“水錘”效應，使軟起甚至水泵損壞。為減少和防止“水錘”效應，需要電動機逐步停機，即軟停車，采用軟啟動器能滿足這一要求。在泵站中，應用軟停車技術(shù)可避免泵站的“拍門”損壞，減少維修費用和維修工作量。5.軟啟動器輕載節(jié)能?；\型異步電動機是感性負載，在運行中，定子線圈繞組中的電流滯后于電壓。如電動機工作電壓不變，處于輕載時。功率因數(shù)低;處于重載時，功率因數(shù)高。在輕載時，軟啟動器通過降低電動機端電壓，提高功率因數(shù)，減少電動機的鋼耗、鐵耗，達到輕載節(jié)能的目的;負載重時，則提高電動機端電壓，確保電動機正常運行。淄博科恩軟啟動器生產(chǎn)商</p><div

style="text-indent:25px">電機軟啟動器是主要采用電力電子技術(shù)和微處理技術(shù)以及現(xiàn)代控制理論而設計生產(chǎn)的具有先進水平的新型啟動設備，電機軟啟動器主要具有抗干擾功能、可靠性高、多重保護功能等特點，根據(jù)這些特點電機軟啟動器得到了普遍應用，主要應用于風機、水泵、輸送類及壓縮機等領(lǐng)域。電機軟啟動器是一種集電機軟起動、軟停車、輕載節(jié)能等多功能于一體的新型電機控制裝備。軟啟器主要是采用三相反并聯(lián)晶閘管作為調(diào)壓器將它連接在電源和電動機定子之間，使軟啟動器啟動電動機時，晶閘管所輸出的電壓逐漸增加，同時電動機也逐漸加速，直到晶閘管全部疏通，電動機工作在額定電壓的機械特性上，才能實現(xiàn)平滑啟動，降低啟動電流，來避免啟動電流過大而產(chǎn)生跳閘的現(xiàn)象。待電機達到額定轉(zhuǎn)數(shù)時，啟動過程結(jié)束，軟啟動器自動用旁路所接觸器來取代晶閘管，為電動機正常運轉(zhuǎn)提供額定電壓，以降低晶閘管的熱損耗同時還延長軟啟動器的使用壽命，提高其工作效率。同時電氣軟啟動器還提供了軟停車的功能，軟停車與軟啟動過程真好相反，電壓逐漸降低，轉(zhuǎn)數(shù)逐漸下降到零，避免自由停車引起的轉(zhuǎn)矩沖擊。</p><p> 過載保護功能。一般電機的過載保護是通過熱元件來實現(xiàn)的，熱元件在電動機的啟動瞬間過電流而產(chǎn)生誤<span style="font-size:12px;">動作。為避免誤動，用戶常加大熱元件的設定電流，因而使得過載保護的靈敏度不夠，使過載保護形同虛設。</span><span style="font-size:12px;">而軟啟動器內(nèi)置的過載保護功能是根據(jù)啟動負荷的輕重（即啟動時間的長短）來選擇不同的脫扣特性曲線，以</span><span style="font-size:12px;">避免突然啟動過程中誤跳。由于它的過載保護是可編程的，從而為用戶提供了更大的靈活性。選用帶內(nèi)置過載</span><span style="font-size:12px;">保護功能的軟啟動器還可以省去熱繼電器，使控制柜內(nèi)布線簡單。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="淄博科恩軟啟動器生產(chǎn)商,科恩軟啟動器"

2.可控硅燒毀：可控硅擊穿或，此類故障不分國內(nèi)外品牌，因廠家而易，但這類故障率低，而且主要問題出現(xiàn)在餅式可控硅的安裝工藝上。　 3.控制器燒損：控制器燒損這類故障主要是控制器的電源和觸發(fā)電路以及輸入電路三部分容易燒毀。 4.軟啟動器誤動作：電動機在運行的裝態(tài)下因電機軟起動器受干擾而停機在停止狀態(tài)下其中原因可能是產(chǎn)品的質(zhì)量問題或是線路布局的問題。淄博科恩軟啟動器生產(chǎn)商</p><p
