class="box"><p><p>污水處理廠該如何選擇軟啟動器。污水處理廠一般使用軟啟動器的場景是水泵上，那么該如何為其選擇軟啟動器呢。首先我們需要考慮到，污水處理廠其實是有兩種水泵的，一種是清水泵，一種是污水泵。首先清水泵。因為只是常規(guī)的清水泵，所以我們只要選擇常規(guī)對應(yīng)功率的軟啟動器即可。并沒有太多需要注意的。對應(yīng)艾克威爾的品牌，我們推薦使用mg3系列軟啟動器，可以很好的解決水錘效應(yīng)。其次則是污水泵。污水泵和清水泵不同，有些需要處理的污水因為雜志較多，甚至可能出現(xiàn)淤泥狀，這對電機本身也是增大了符合，瞬間啟動電流會比常規(guī)同等功率的電機大很多，淄博科恩軟啟動器找哪家，淄博科恩軟啟動器找哪家。那么這個時候我們就需要考慮，把軟啟動器加大一檔，甚至根據(jù)現(xiàn)場的情況，淄博科恩軟啟動器找哪家，我們可以考慮加大兩檔處理。對應(yīng)艾克威爾的軟啟動器，我們推薦使用Mg6系列軟啟動器，加大一檔話，則是37KW的電機可以選用45KW的軟啟動器。淄博科恩軟啟動器找哪家</p><div

軟啟動器，應(yīng)用先進的軟件設(shè)計方法和的硬件技術(shù)，采用晶閘管相移技術(shù)，使加到電動機上的電壓按某一規(guī)律慢慢達到全電壓，通過設(shè)置適當?shù)目刂茀?shù)，可以使電動機的轉(zhuǎn)矩和電流與負載要求得到較好的匹配。同時，通過軟件與硬件的配合，對軟啟動器本身、電動機、負載提供的保護。一般來講，電動機功率的選擇總是大于比較大負載要求，其結(jié)果是電動機很少在額定功率下運行，經(jīng)常處于輕載或變載的情況，能量嚴重浪費。軟啟動在運行時，首先保持輸出額定電壓，以保證電動機和負載在加速后進入穩(wěn)定狀態(tài)；保持一段很短時間之后，自動進入節(jié)電運行階段。其獨有的節(jié)電控制軟件自動負載變化，通過不斷對電流和功率因數(shù)的綜合計算，進行實時調(diào)節(jié)、更新觸發(fā)角，控制輸出電壓，降低勵磁電流，提高功率因數(shù)，實現(xiàn)節(jié)電。淄博科恩軟啟動器找哪家</p><div

軟起動器具有軟起動、軟停止、泵控制功能、定時低速運行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動力設(shè)備控制中具有傳統(tǒng)降壓起動器不可比擬的優(yōu)越性。三相異步電動機有很多優(yōu)點，但也有兩個致命的弱點：一是啟動性能差；二是調(diào)速性能差。隨著電力半導(dǎo)體技術(shù)的發(fā)展以及大功率晶體管在工業(yè)控制領(lǐng)域里的應(yīng)用，有兩個典型的產(chǎn)品改善了異步電動機這兩個弱點，一是變頻器，二是軟啟動器。變頻器改善異步電動機的調(diào)速性能；軟起動在起動時間ts內(nèi)，電機的端電壓從設(shè)定的初始值逐漸增至滿壓，電機平滑、無級地加速。同時ts可調(diào)節(jié)(通常在60s之間),這有利于與低壓斷路器之間的配合，防止低壓斷路器的瞬時脫扣器在電機起動時誤跳閘。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，熱元件在電動機起動過程中很難避開電機的起動電流而產(chǎn)生誤動作。為避免誤動，用戶常加大熱元件的動作電流，因而使得過載保護的靈敏度不夠，使過載保護形同虛設(shè)。而軟起動器內(nèi)置的過載保護功能是根據(jù)起動負荷的輕重(即起動時間的長短)來選擇不同的脫扣特性曲線，以避免在起動過程中誤跳。由于它的過載保護是可編程的，軟啟動器廠家從而為用戶提供了更大的靈活性。 </p><p> 現(xiàn)在跟大家講講根據(jù)負載性質(zhì)選擇不同型號的軟啟動器來選用軟啟動器軟啟動器選型：目前市場上常見的軟啟動器有旁路型軟啟動器、無旁路型軟啟動器、節(jié)能型軟啟動器等。下面我們來一一講它們的功能：旁路型軟啟動器：在電動機達到額定轉(zhuǎn)數(shù)時，用旁路接觸器取代已完成任務(wù)的軟啟動器，降低晶閘管的熱損耗，提高其工作效率。也可以用一臺軟啟動器去啟動多臺電動機。無旁路型軟啟動器：晶閘管處于全導(dǎo)通狀態(tài)，電動機工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時重復(fù)工作的電動機。節(jié)能型軟啟動器：當電動機負荷較輕時，軟啟動器自動降低施加于電動機定子上的電壓，減少電動機電流勵磁分量，提高電動機功率因數(shù)。軟啟動器如何選規(guī)格?根據(jù)電動機的標稱功率，電流負載性質(zhì)選擇啟動器，一般軟啟動器容量稍大于電動機工作電流，還應(yīng)考慮保護作用是否完備，例如：缺相保護、短路保護、過載保護、逆序保護、過壓保護、欠壓保護等。

軟起動器主回路采用晶閘管,通過逐步改變晶閘管的導(dǎo)通角來抬升電壓,完成起動過程,這是軟起動器的基本原理。目前在低壓軟起動器市場,產(chǎn)品繁多,但是高壓軟起動器產(chǎn)品還是比較少。高壓軟起動器與低壓軟起動器基本原理一樣，但是高壓軟起動器與低壓軟起動器相比,有些地方存在著其特殊性：1.高壓軟起動器在高壓環(huán)境下工作,各種電氣元器件的絕緣性能一定要好,電子芯片的抗干擾能力要強。高壓軟起動器組成電氣柜時,電氣元器件的布局以及與高壓軟起動器與其它電氣設(shè)備的連接也是非常重要的。2.高壓軟起動器必須有一個高性能的控制,能對信號進行及時和快速地處理。因此這個控制一般采用高性能的DSP芯片,而不是低壓軟起動器的普通單片機芯。低壓軟起動器主回路由三組反并聯(lián)的晶閘管組成。而在高壓軟起動器中,由于目前單只高壓晶閘管的耐壓能力不夠,所以必須由多個高壓晶閘管串聯(lián)進行分壓。但是每個晶閘管的性能參數(shù)沒有完全一致。晶閘管參數(shù)的不一致，會導(dǎo)致晶閘管開通時間不一致，從而導(dǎo)致晶閘管的損壞。因此在晶閘管的選配上,必須保證每一相的晶閘管參數(shù)盡可能地一致，并且每一相晶閘管的RC濾波電路的元件參數(shù)盡可能一致。3．高壓軟起動器的工作環(huán)境容易受到各種電磁干擾。淄博科恩軟啟動器找哪家</p><p
