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：(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。

軟起動器就是應用**效用**突出的控制設備,軟啟動器在不同領域、不同行業(yè)甚至是不同設備上的應用往往也有著極大的不同。1、軟起動器在城市雨水排污泵站、污水處理廠中的應用雨水排污站的泄水池是雨水、生活污水、工業(yè)污水的集中地，為確保泄水池液位保持在允許的范圍內(nèi)，通過檢測泄水池液位來自動控制排污泵組工作以保證污水的正常排放。2、軟起動器應用于自來水廠、加壓泵站清水泵主要實現(xiàn)大功率水泵電機的軟起動、軟停車，重點消除、減弱水錘的危害。當液體在管路系統(tǒng)中受外力突然加速或突然減速、或改變流向就會造成水錘，水錘危害很大，輕則引起管路，系統(tǒng)振動，發(fā)出噪聲，重則造成損壞，甚至使泵房被淹。3、軟起動器在消防泵控制中的應用消火栓泵、噴淋泵是工業(yè)和民用建筑消防設施的重要消防裝備，其運行可靠性極其重要，隨著大中型建設項目的興建，所配置的消火栓泵、噴淋泵功率、揚程增大，傳統(tǒng)的降壓起動方式凸顯其缺點，尤其高層建筑水錘危害嚴重，給設備運行帶來不安全因素，目前軟起動在消防泵控制中得到的應用。4、軟起動器在在各種類型的深井潛水泵、長軸泵中的應用一般深井潛水泵揚程較大，非軟停機時水錘現(xiàn)象明顯。 </p><p> 晶閘管導通條件為：加正向電壓且門極有觸發(fā)電流;其派生器件有：快速晶閘管，雙向晶閘管，逆導晶閘管，光控晶閘管等。它是一種大功率開關型半導體器件，在電路中用文字符號為“V”、“VT表示。晶閘管在工作過程中，它的陽極(A)和陰極(K)與電源和負載連接，組成晶閘管的主電路，晶閘管的門極G和陰極K與控制晶閘管的裝置連接，組成晶閘管的控制電路。高壓晶閘管軟啟動器為半控型電力電子器件，它的工作條件如下：1.晶閘管承受反向陽極電壓時，不管門極承受何種電壓，晶閘管都處于反向阻斷狀態(tài)。2.晶閘管承受正向陽極電壓時，*在門極承受正向電壓的情況下晶閘管才導通。這時晶閘管處于正向?qū)顟B(tài)，這就是晶閘管的閘流特性，即可控特性。3.晶閘管在導通情況下，只要有一定的正向陽極電壓，不論門極電壓如何，晶閘管保持導通，即晶閘管導通后，門極失去作用。門極只起觸發(fā)作用。4.晶閘管在導通情況下，當主回路電壓(或電流)減小到接近于零時，晶閘管關斷。

電機軟啟動器是一種集軟啟動、軟停車、輕載節(jié)能和多功能保護于一體的新穎電機控制裝置，的應用于風機、水泵、輸送類及壓縮機等負載，是傳統(tǒng)的星/三角轉(zhuǎn)換、自耦降壓磁控降壓等降壓設備的理想換代產(chǎn)品。在某些變頻器大材小用的場合，也能使用軟啟動器來進行代替。節(jié)約了成本的同時，也使不必要的浪費得到控制。那么是哪些方面造就了電機軟啟動器的高性價比呢?1、啟動方式：根據(jù)負載特點選擇不同的啟動模式及參數(shù)設置，可很大程度的使電動機實現(xiàn)比較好的啟動效果，三種啟動方式：電壓斜坡啟動——可得到比較大的輸出扭矩;限流啟動——可有效地限制啟動電流;點動——可實現(xiàn)試車調(diào)試功能。2、高技術性能：由于采用了高性能微處理器及強大的軟件支持功能使控制電路得以簡化，無需對電路參數(shù)進行調(diào)整，即可獲得一致、準確及快速的執(zhí)行速度;**度抗干擾功能。3、高可靠性：電機軟啟動器所有電器元件均經(jīng)過嚴格的篩選，其主控板還須經(jīng)過72小時高溫循環(huán)試驗和振動試驗，從而保證了出廠產(chǎn)品的高可靠性。4、優(yōu)化的結(jié)構(gòu)：獨特緊湊的模塊化結(jié)構(gòu)及上進線下出線的連接方式，非常方便用戶的集成、成套。5、鍵盤設置功能：電機軟啟動器擁有便捷直觀的操作顯示鍵盤，可根據(jù)不同負載。淄博科恩軟啟動器制造商</p><p

1.電機軟啟動器本身是沒有短路保護的，為了保護其中的晶閘管應該采用快速熔斷器，因此我們在要根據(jù)軟啟動器的額定電流來選擇快速熔斷器，因為低壓斷路器開斷時間較長(約為0.1S)，所以不宜用于晶閘管的保護。 2.當我們在使用電機軟啟動器時，使電動機制動停機，主要的原因是由于晶閘管不導通，所以我們在檢修電動機或線路時，必須要先斷開供電電源，這樣可以使軟啟動器與電源之間增設斷路器 3.電機軟啟動器在內(nèi)部設置了多種保護功能，在具體使用時要根據(jù)實際的需要，通過編程來選擇保護功能或者使某些保護功能失效，例如：突然斷電時過負載造成的損失會更大，其過負載保護應作用與信號而不應用于切斷電路。 4.當電機軟啟動器功率較大或者臺數(shù)較多時，產(chǎn)生的高次諧波會對電網(wǎng)所造成不良影響，并且對電子設備產(chǎn)生干擾，當電動機平穩(wěn)啟動到正常轉(zhuǎn)速時，旁路接觸器閉合，把軟啟動器短接，在啟動完成之后，大功率晶閘管不在工作，從而消去除高次諧波對電網(wǎng)以及電子設備的干擾。淄博科恩軟啟動器制造商</p><p
