現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號的軟啟動(dòng)器來選用軟啟動(dòng)器軟啟動(dòng)器選型：目前市場上常見的軟啟動(dòng)器有旁路型軟啟動(dòng)器、無旁路型軟啟動(dòng)器、節(jié)能型軟啟動(dòng)器等。下面我們來一一講它們的功能：旁路型軟啟動(dòng)器：在電動(dòng)機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí)，用旁路接觸器取代已完成任務(wù)的軟啟動(dòng)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(dòng)器去啟動(dòng)多臺電動(dòng)機(jī)。無旁路型軟啟動(dòng)器：晶閘管處于全導(dǎo)通狀態(tài)，電動(dòng)機(jī)工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時(shí)重復(fù)工作的電動(dòng)機(jī)。節(jié)能型軟啟動(dòng)器：當(dāng)電動(dòng)機(jī)負(fù)荷較輕時(shí)，軟啟動(dòng)器自動(dòng)降低施加于電動(dòng)機(jī)定子上的電壓，減少電動(dòng)機(jī)電流勵(lì)磁分量，提高電動(dòng)機(jī)功率因數(shù)。軟啟動(dòng)器如何選規(guī)格?根據(jù)電動(dòng)機(jī)的標(biāo)稱功率，電流負(fù)載性質(zhì)選擇啟動(dòng)器，一般軟啟動(dòng)器容量稍大于電動(dòng)機(jī)工作電流，還應(yīng)考慮保護(hù)作用是否完備，例如：缺相保護(hù)、短路保護(hù)、過載保護(hù)、逆序保護(hù)、過壓保護(hù)、欠壓保護(hù)等。淄博科恩軟啟動(dòng)器怎么聯(lián)系</p><div

電機(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)用場合，不允許電機(jī)瞬間關(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)，使管道，甚至水泵遭到損壞.為減少和防止“水錘“效應(yīng).需要電機(jī)逐漸停機(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)可遇免泵站的“拍門“損壞，減少維修費(fèi)用和維修工作量.。<span style="font-size:12px;">軟啟動(dòng)器中的軟停車功能是，晶閘管在得到停機(jī)指令后，從全導(dǎo)通逐漸地減小導(dǎo)通角.經(jīng)過一定時(shí)間過渡到全關(guān)閉的過程.停車的時(shí)間根據(jù)實(shí)際需要可在0-120s調(diào)整。</span> </p><p> 由于設(shè)備的起動(dòng)一停止特性，不希望電潛泵循環(huán)運(yùn)行?！翱缇€路”起動(dòng)導(dǎo)致電流波動(dòng)為標(biāo)準(zhǔn)工作電流的5-8倍。這種波動(dòng)能損壞馬達(dá)和電纜，還會(huì)引起線路電壓紊亂。而停車(會(huì)引起較大的電流量和電壓峰值。因此，許多操作者常常不建議使電潛泵設(shè)備更多的起動(dòng)和停車)，除非需要.這就給使用電潛泵帶來了許多設(shè)計(jì)問題。在設(shè)計(jì)問題上，若電潛泵選小了，泵一定被拖住使產(chǎn)量降低.若泵尺寸設(shè)計(jì)大了，會(huì)造成油井有停泵的趨勢。在增加井口回壓來減小離心泵的排量時(shí)，原采用循環(huán)運(yùn)行。這是不希望出現(xiàn)的。由于施加回壓要帶來能量的浪費(fèi)，并引起泵內(nèi)止推軸承發(fā)生問題而導(dǎo)致過早的損壞。如果減小電壓或電潛泵采用軟啟動(dòng)顯示出消除循環(huán)運(yùn)行的不利影響，那么電潛泵的設(shè)計(jì)就變得容易的多.泵排量可選為油井排量的25-30%，這樣每天油井生產(chǎn)有足夠的時(shí)數(shù)來滿足油井排量.目前所使用高電壓起動(dòng)的標(biāo)準(zhǔn)電氣設(shè)備大功率感應(yīng)式馬達(dá)，是一個(gè)電力一機(jī)械“跨線路”起動(dòng)器.它能控制電壓高達(dá)2500V和1000hp的功率，而本身不發(fā)生問題.按一下按鈕即可起動(dòng)，它激發(fā)一個(gè)110VAC繼電器，繼而依次接通主電源繼電器.起動(dòng)幾乎是瞬時(shí)的。每當(dāng)使用通常方法進(jìn)行控制起動(dòng)，在常用的星形接三相電的轉(zhuǎn)換線路中。

軟起動(dòng)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(dòng)過程,這是軟起動(dòng)器的基本原理。目前在低壓軟起動(dòng)器市場,產(chǎn)品繁多,但是高壓軟起動(dòng)器產(chǎn)品還是比較少。高壓軟起動(dòng)器與低壓軟起動(dòng)器基本原理一樣，但是高壓軟起動(dòng)器與低壓軟起動(dòng)器相比,有些地方存在著其特殊性：1.高壓軟起動(dòng)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(qiáng)。高壓軟起動(dòng)器組成電氣柜時(shí),電氣元器件的布局以及與高壓軟起動(dòng)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(dòng)器必須有一個(gè)高性能的控制,能對信號進(jìn)行及時(shí)和快速地處理。因此這個(gè)控制一般采用高性能的DSP芯片,而不是低壓軟起動(dòng)器的普通單片機(jī)芯。低壓軟起動(dòng)器主回路由三組反并聯(lián)的晶閘管組成。而在高壓軟起動(dòng)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(gè)高壓晶閘管串聯(lián)進(jìn)行分壓。但是每個(gè)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(huì)導(dǎo)致晶閘管開通時(shí)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(dòng)器的工作環(huán)境容易受到各種電磁干擾。淄博科恩軟啟動(dòng)器怎么聯(lián)系</p><p
