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(dǎo)通角，使電動機啟動電流從零線性上升至設(shè)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?zé)o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(yīng)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(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(yīng)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。淄博科恩軟啟動器代理科恩電氣以質(zhì)量求生存，以信譽求發(fā)展！</p><div

style="font-size:12px;">動作。為避免誤動，用戶常加大熱元件的設(shè)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(shè)。</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

想的電機保護器？理想的電機保護器不是功能多，也不是所謂技術(shù)的，而是應(yīng)該滿足現(xiàn)場實際需求，做到經(jīng)濟性和可靠性的統(tǒng)一，具有較高的性能價格比。根據(jù)現(xiàn)場的實際情況合理地選擇保護器的種類、功能，長沙軟啟動器同時考慮保護器安裝、調(diào)整、使用簡單方便，更重要的是要選擇高質(zhì)量的保護器。水泵啟動方式有直接啟動，降壓啟動，軟啟動和變頻啟動四種，直接啟動一般適合小功率的電機，我們一般只在15kw以下的泵上使用，價格便宜；降壓啟動是星—三角轉(zhuǎn)換啟動，就是啟動是分兩次加速才達到額定轉(zhuǎn)速的，一般在，價格適中；軟啟動是逐漸增加到額定轉(zhuǎn)速的，對泵的沖擊很小，價格比較高，一般是降壓啟動的3倍；高級的是變頻啟動，除了有軟啟動的優(yōu)點外，還可以設(shè)定在任意轉(zhuǎn)速工作，對節(jié)能降耗有效果。在關(guān)閉泵出口閥，打開泵進口閥，并能確保水泵“自灌”(液位高于泵的進口的管道條件下，水泵的啟動程序是：啟動電機，待電機正常運行時，緩緩打開出口閥，使電流慢慢加大。但在無人操作(開閥)，又是自動啟泵，且管道直徑與長度大(管道內(nèi)的水質(zhì)量會很大)，如電機快速啟動，要迅速推動大質(zhì)量的水加速(如同火車要很快加速)，會使電機啟動電流很大。科恩電氣設(shè)備的引進更加豐富了公司的設(shè)備品種，為用戶提供了更多的選擇空間。</p><div

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(lǐng)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(guān)，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(dāng)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。科恩電氣深受行業(yè)客戶的好評，值得信賴。淄博科恩軟啟動器代理</p><p

軟啟動器的優(yōu)越性能有哪些(1)軟啟動器在起動過程中，能控制電機電壓按線性增加，以使電機電流也線性增加，因此不會對電網(wǎng)造成沖擊，不會對配電回路造成更大的電壓降，延長了電氣設(shè)備的使用壽命。并且電機起動電流，起動轉(zhuǎn)矩可調(diào)節(jié)，滿足了生產(chǎn)工藝的要求。(2)軟啟動器在起動過程當(dāng)中不受電網(wǎng)電壓波動的影響。當(dāng)電網(wǎng)電壓出現(xiàn)波動時，由于軟起動器的晶閘管控制電路中引入了電流反饋，使得在整個起動過程當(dāng)中，通過控制晶閘管的觸發(fā)角和導(dǎo)通角來保持起動電流的恒定，使電動機平穩(wěn)起動，不受配電回路電壓波動的影響。(3)應(yīng)用的范圍非常廣。通過調(diào)節(jié)軟啟動器的電壓、電流和時間參數(shù)，可以滿足不同的起動電流、轉(zhuǎn)矩和時間以及各種停止的要求，時間電動機的軟起動和軟停止。(4)對于重復(fù)短時工作制的設(shè)備，電機長時間運行在空載和低負載狀態(tài)下，短時運行于重負載狀態(tài)下。軟啟動器在滿足其他要求的同時，還有節(jié)能控制環(huán)節(jié)，提高空載和低負荷時的功率因素，以達到節(jié)能目的。(5)一臺軟啟動器可以起動多臺電動機。尤其是對于外接法只要加上一定的輔助電路，就能實現(xiàn)用一臺軟啟動器帶動多臺電動機，這樣就的減少了成本。總之，深入的了解生產(chǎn)工藝過程，了解對起動和停止的要求。淄博科恩軟啟動器代理</p><p
