從長(zhǎng)期來(lái)看：變頻軟起將會(huì)成為軟起動(dòng)器（西馳分級(jí)變頻軟起動(dòng)器）的主流。各種形式的降壓軟起動(dòng)將與星三角起動(dòng)等技術(shù)一起歸并為傳統(tǒng)的起動(dòng)技術(shù)。隨著變頻器價(jià)格的逐漸下降，可靠性的進(jìn)一步提高，也隨著技術(shù)人員水平的提高，**為軟起動(dòng)而選用變頻器將不再會(huì)被人們認(rèn)為是一種。變頻軟起動(dòng)勝出的根本原因是：它可以在限流（起動(dòng)電流不超過(guò)電機(jī)額定電流值）的同時(shí)獲得大的起動(dòng)轉(zhuǎn)矩，可以實(shí)現(xiàn)包括軟停止在內(nèi)的各種起動(dòng)功能。對(duì)于**為軟起動(dòng)而制作的變頻器而言，應(yīng)在起動(dòng)完成后使變頻器脫電，使電動(dòng)機(jī)直掛電網(wǎng)。這樣做的目的是節(jié)能，消除無(wú)謂的損耗。這種操作應(yīng)該在安全的不引起電流沖擊的條件下完成，或者叫做軟切換。軟切換的可能步驟是“先脫（電）后掛（網(wǎng)）”或“先掛后脫”，軟切換應(yīng)該在基本上不增加硬件（例如軟切換電抗器）的條件下主要靠軟件完成。淄博科恩軟啟動(dòng)器價(jià)格行情</p><div

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(lái)了許多設(shè)計(jì)問(wèn)題。在設(shè)計(jì)問(wèn)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(shì)。在增加井口回壓來(lái)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(lái)能量的浪費(fèi)，并引起泵內(nèi)止推軸承發(fā)生問(wèn)題而導(dǎo)致過(guò)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(lái)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(wèn)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。 </p><p> 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)如下。(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(guò)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(guò)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(méi)有超常地發(fā)熱。

軟起動(dòng)器具有軟起動(dòng)、軟停止、泵控制功能、定時(shí)低速運(yùn)行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動(dòng)力設(shè)備控制中具有傳統(tǒng)降壓起動(dòng)器不可比擬的優(yōu)越性。三相異步電動(dòng)機(jī)有很多優(yōu)點(diǎn)，但也有兩個(gè)致命的弱點(diǎn)：一是啟動(dòng)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(gè)典型的產(chǎn)品改善了異步電動(dòng)機(jī)這兩個(gè)弱點(diǎn)，一是變頻器，二是軟啟動(dòng)器。變頻器改善異步電動(dòng)機(jī)的調(diào)速性能；軟起動(dòng)在起動(dòng)時(shí)間ts內(nèi)，電機(jī)的端電壓從設(shè)定的初始值逐漸增至滿壓，電機(jī)平滑、無(wú)級(jí)地加速。同時(shí)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(shí)脫扣器在電機(jī)起動(dòng)時(shí)誤跳閘。過(guò)載保護(hù)功能一般電機(jī)的過(guò)載保護(hù)是通過(guò)熱元件來(lái)實(shí)現(xiàn)的，熱元件在電動(dòng)機(jī)起動(dòng)過(guò)程中很難避開電機(jī)的起動(dòng)電流而產(chǎn)生誤動(dòng)作。為避免誤動(dòng)，用戶常加大熱元件的動(dòng)作電流，因而使得過(guò)載保護(hù)的靈敏度不夠，使過(guò)載保護(hù)形同虛設(shè)。而軟起動(dòng)器內(nèi)置的過(guò)載保護(hù)功能是根據(jù)起動(dòng)負(fù)荷的輕重(即起動(dòng)時(shí)間的長(zhǎng)短)來(lái)選擇不同的脫扣特性曲線，以避免在起動(dòng)過(guò)程中誤跳。由于它的過(guò)載保護(hù)是可編程的，軟啟動(dòng)器廠家從而為用戶提供了更大的靈活性。淄博科恩軟啟動(dòng)器價(jià)格行情</p><p

軟起動(dòng)器主回路采用晶閘管,通過(guò)逐步改變晶閘管的導(dǎo)通角來(lái)抬升電壓,完成起動(dòng)過(guò)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(chǎng),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(duì)信號(hào)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(méi)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)器價(jià)格行情</p><p
