現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號(hào)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(chǎng)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(tái)軟啟動(dòng)器去啟動(dòng)多臺(tái)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，淄博科恩軟啟動(dòng)器代理，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，淄博科恩軟啟動(dòng)器代理，例如：缺相保護(hù)、短路保護(hù)、過載保護(hù)、逆序保護(hù)，淄博科恩軟啟動(dòng)器代理、過壓保護(hù)、欠壓保護(hù)等。我公司將以優(yōu)良的產(chǎn)品，周到的服務(wù)與尊敬的用戶攜手并進(jìn)！淄博科恩軟啟動(dòng)器代理</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。

有電機(jī)有負(fù)載，就需要使用到電機(jī)軟啟動(dòng)器，我們知道，電機(jī)直接啟動(dòng)停止會(huì)給電網(wǎng)電壓帶來很大沖擊，對(duì)我們電機(jī)本身也會(huì)帶來很大傷害，嚴(yán)重縮短使用壽命，甚至?xí)陔妷弘娏鬟^大時(shí)，燒毀電機(jī)。這時(shí)候，選擇一款合適的電機(jī)軟啟動(dòng)器就非常重要了。那么，你知道電機(jī)軟啟動(dòng)器怎么選擇嗎？一般來說，負(fù)載電機(jī)的功率達(dá)到，我們就建議使用軟啟動(dòng)器來進(jìn)行電機(jī)起停、保護(hù)工作。（這里家庭電器不列在內(nèi)）常見的風(fēng)機(jī)、水泵這種類型的負(fù)載，屬于輕型負(fù)載，選擇輕載軟起動(dòng)器，功率也可以一比一選擇，如：15KW的風(fēng)機(jī)，就可以選擇15KW的Mg3軟啟動(dòng)器和Mg6軟啟動(dòng)器。破碎機(jī)、球磨機(jī)、皮帶機(jī)這些，則屬于重型負(fù)載，需要選擇重載軟起動(dòng)器，而且要根據(jù)現(xiàn)場(chǎng)環(huán)境來選擇放大一檔到兩檔。如：110KW的破碎機(jī)，就可以選擇132KW的FC1000軟起動(dòng)器。礦用軟啟動(dòng)器，則根據(jù)井下和井上的使用環(huán)境，區(qū)分選擇，井下是需要防爆型軟啟動(dòng)器的，井上則是通用型軟啟動(dòng)器的。高壓軟啟動(dòng)器，在選擇時(shí)，要看電網(wǎng)電壓，如果電網(wǎng)電壓是10KV，我們就需要選擇10KV的高壓軟啟動(dòng)器，而不能為省成本選擇6KV，電壓等級(jí)不對(duì)，會(huì)對(duì)安全生產(chǎn)帶來很大，可能發(fā)生的危險(xiǎn)。 </p><p> 從長(zhǎng)期來看：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。科恩電氣具有一支經(jīng)驗(yàn)豐富、技術(shù)力量過硬的專業(yè)技術(shù)人才管理團(tuán)隊(duì)。</p><div
