晶閘管導(dǎo)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(dǎo)晶閘管，光控晶閘管等。它是一種大功率開關(guān)型半導(dǎo)體器件，在電路中用文字符號(hào)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(fù)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(dòng)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(shí)，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(shí)，*在門極承受正向電壓的情況下晶閘管才導(dǎo)通。這時(shí)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(dǎo)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(dǎo)通，即晶閘管導(dǎo)通后，門極失去作用。門極只起觸發(fā)作用。4.晶閘管在導(dǎo)通情況下，當(dāng)主回路電壓(或電流)減小到接近于零時(shí)，晶閘管關(guān)斷。淄博科恩軟啟動(dòng)器代理公司將以優(yōu)異的產(chǎn)品，完善的服務(wù)與尊敬的用戶攜手并進(jìn)！</p><div

變頻器和軟啟動(dòng)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(dòng)機(jī)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(shí)改變頻率。變頻器具備所有軟啟動(dòng)器和其他啟動(dòng)控制裝置的功能，且啟動(dòng)特性上較之其他電動(dòng)機(jī)啟動(dòng)裝置有比較大的優(yōu)勢(shì).因此完全可以用作電動(dòng)機(jī)的軟啟動(dòng)控制。但之所以目前在電動(dòng)機(jī)的啟動(dòng)控制領(lǐng)城軟啟動(dòng)器仍占據(jù)主要位置.是由于變頻器固有的一些劣勢(shì)，且短期內(nèi)很難克服.只有克服了這些劣勢(shì)之后.變頻器才有可能取代軟啟動(dòng)器。變頻器的特點(diǎn)：(1)啟動(dòng)轉(zhuǎn)矩大，功率因數(shù)高。因?yàn)殡妱?dòng)機(jī)的功率因數(shù)與工作頻率有關(guān)，在電動(dòng)機(jī)低速運(yùn)行時(shí)工頻電源下的功率因數(shù)遠(yuǎn)低于低頻電源下的功率因數(shù)。變頻器可以控制電動(dòng)機(jī)從低頻起步.且在整個(gè)啟動(dòng)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(dòng)期間采取減載卸載等措施時(shí).變頻器容量可以比電動(dòng)機(jī)容量小。當(dāng)然，啟動(dòng)完成后變頻器需要退出運(yùn)行。(3)啟動(dòng)電流小。變頻器一電動(dòng)機(jī)拖動(dòng)系統(tǒng)允許的啟動(dòng)時(shí)間可以很長(zhǎng)。因?yàn)樵谶@期間，電動(dòng)機(jī)電流可以不超過電動(dòng)機(jī)額定電流，因此，不論是變頻器、電動(dòng)機(jī)還是其他元器件均沒有超常地發(fā)熱。 </p> <p> <br /> </p><p> 軟啟動(dòng)器1.無沖擊電流，軟啟動(dòng)器在啟動(dòng)電動(dòng)機(jī)時(shí)，通過逐漸增大晶閘管導(dǎo)通角，使電動(dòng)機(jī)啟動(dòng)電流從零線性上升至設(shè)定值。2.恒流啟動(dòng)，軟啟動(dòng)器可以引人電流閉環(huán)控制，使電動(dòng)機(jī)在啟動(dòng)過程中保持恒流，確保電動(dòng)機(jī)平穩(wěn)啟動(dòng)。3.根據(jù)負(fù)載情況及電網(wǎng)繼電保護(hù)特性選擇，可自由地?zé)o級(jí)調(diào)整至比較好的啟動(dòng)電流。4.電動(dòng)機(jī)停機(jī)時(shí)，傳統(tǒng)的控制方式都是通過瞬間停電完成的。但有許多應(yīng)用場(chǎng)合，不允許電動(dòng)機(jī)瞬問關(guān)機(jī)。例如:高層建筑、大樓的水泵系統(tǒng)，如果瞬間停機(jī)，會(huì)產(chǎn)生巨大的“水錘”效應(yīng)，使軟起甚至水泵損壞。為減少和防止“水錘”效應(yīng)，需要電動(dòng)機(jī)逐步停機(jī)，即軟停車，采用軟啟動(dòng)器能滿足這一要求。在泵站中，應(yīng)用軟停車技術(shù)可避免泵站的“拍門”損壞，減少維修費(fèi)用和維修工作量。5.軟啟動(dòng)器輕載節(jié)能?；\型異步電動(dòng)機(jī)是感性負(fù)載，在運(yùn)行中，定子線圈繞組中的電流滯后于電壓。如電動(dòng)機(jī)工作電壓不變，處于輕載時(shí)。功率因數(shù)低;處于重載時(shí)，功率因數(shù)高。在輕載時(shí)，軟啟動(dòng)器通過降低電動(dòng)機(jī)端電壓，提高功率因數(shù)，減少電動(dòng)機(jī)的鋼耗、鐵耗，達(dá)到輕載節(jié)能的目的;負(fù)載重時(shí)，則提高電動(dòng)機(jī)端電壓，確保電動(dòng)機(jī)正常運(yùn)行?？贫麟姎庠诳蛻艉托袠I(yè)中樹立了良好的企業(yè)形象。</p><div

高壓軟起動(dòng)器對(duì)信號(hào)的檢測(cè)比低壓軟起動(dòng)器要求更高。高壓軟起動(dòng)器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動(dòng)器所用的真空接觸器和真空斷路器在其分?jǐn)嗪烷]合過程中會(huì)產(chǎn)生大量的電磁干擾。所以對(duì)檢測(cè)到的信號(hào)不*要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號(hào)。軟起動(dòng)器在完成起動(dòng)過程后，要切換到旁路運(yùn)行狀態(tài)，如何平滑地切換到運(yùn)行狀態(tài)，這也是軟起動(dòng)器的一個(gè)難點(diǎn)，如何選準(zhǔn)旁路點(diǎn)非常重要。旁路點(diǎn)早了，電流沖擊非常大，即使在低壓條件下，也會(huì)造成三相電源中斷路器跳閘，甚至?xí)p壞斷路器。高壓條件下危害更大。旁路點(diǎn)遲了，電機(jī)抖動(dòng)得厲害，影響負(fù)載正常工作。因此，旁路信號(hào)的硬件檢測(cè)電路必須非常精確，并且程序處理也要恰到好處。綜上所述，盡管低壓軟起動(dòng)器和高壓軟起動(dòng)器的基本原理一致，但高壓軟起動(dòng)器存在的諸多技術(shù)難題，使得在低壓軟起動(dòng)器遍地開花的情況下，高壓軟起動(dòng)器的成熟產(chǎn)品并不多見。科恩電氣產(chǎn)品**國內(nèi)。淄博科恩軟啟動(dòng)器代理</p><p

style="text-indent:25px">就損傷特殊連接的轉(zhuǎn)子馬達(dá)或線路中的變壓器。這種方法的缺點(diǎn)是增加了馬達(dá)費(fèi)用、昂貴的開關(guān)裝置、降壓部件、必須的機(jī)械裝置維護(hù)、扭矩階躍變化和起動(dòng)時(shí)產(chǎn)生的加速度。通過改進(jìn)可控硅整流谷(SCR)而研創(chuàng)的一種減小電壓的起動(dòng)器，它適用于控制油井大功率值。其基本線路使用六個(gè)連接的可控硅整流器作為三個(gè)全控交流開關(guān)。每個(gè)電源相和馬達(dá)之間安置一個(gè)開關(guān).它是在一個(gè)全橋控制之中限制電流。當(dāng)按圖連接時(shí)，在每個(gè)半循環(huán)期間電路能用改變每個(gè)可控硅整流器接通點(diǎn)來控制負(fù)載的交流功率，使用正確的時(shí)間信號(hào)把它加到可控硅整流器的整流柵進(jìn)行整流。在每個(gè)半循環(huán)中逐漸變化相后角，能平穩(wěn)增加馬達(dá)的功率通量。當(dāng)按“起動(dòng)”按鈕時(shí)，電流迅速上升到預(yù)置的滿載安培數(shù)值，通常是40%.該數(shù)值剛剛處于馬達(dá)負(fù)載裝置起動(dòng)扭矩之下。從這一點(diǎn)，電流將緩慢地開始上升到某些預(yù)置的滿載安培數(shù)值，該數(shù)值保證馬達(dá)在正確的電壓值運(yùn)轉(zhuǎn).時(shí)間間隔可從1s調(diào)到30s.在軟起動(dòng)時(shí)間，電壓和馬達(dá)速度也是緩慢地變化。當(dāng)馬達(dá)電流下降時(shí)，就表示馬達(dá)運(yùn)轉(zhuǎn)正常，此時(shí)起動(dòng)器系統(tǒng)對(duì)電路沒有較大的形響.若在“軟”起動(dòng)循環(huán)完成之后，馬達(dá)電流超過預(yù)置數(shù)值115%滿軟安培數(shù)達(dá)4s。該控制器將使用一個(gè)電流減速階躍關(guān)閉設(shè)備。淄博科恩軟啟動(dòng)器代理</p><p
