1.可以降低電機(jī)的啟動(dòng)電流，從而減少電容量。 2.減少啟動(dòng)應(yīng)力，可以延長電動(dòng)氣以及其他的相關(guān)設(shè)備的使用壽命，維修率低。 3.平穩(wěn)的啟動(dòng)和軟停車，都是避免了傳統(tǒng)的啟動(dòng)設(shè)備的喘振問題等，淄博科恩軟啟動(dòng)器。 4，淄博科恩軟啟動(dòng)器.完善可靠的保護(hù)功能，能夠有效的保護(hù)電機(jī)以及設(shè)備的安全。 5.同時(shí)還能有效的升降起動(dòng)電流以及配電電容量。 6.多種起動(dòng)模式及寬范圍的電流、電壓等設(shè)定，可適應(yīng)多種負(fù)載情況；淄博科恩軟啟動(dòng)器</p><div

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)。淄博科恩軟啟動(dòng)器多少錢</p><div

高壓軟起動(dòng)器對(duì)信號(hào)的檢測比低壓軟起動(dòng)器要求更高。高壓軟起動(dòng)器所在的環(huán)境存在著大量的電磁干擾，并且高壓軟起動(dòng)器所用的真空接觸器和真空斷路器在其分?jǐn)嗪烷]合過程中會(huì)產(chǎn)生大量的電磁干擾。所以對(duì)檢測到的信號(hào)不僅要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號(hào)。軟起動(dòng)器在完成起動(dòng)過程后，要切換到旁路運(yùn)行狀態(tài)，如何平滑地切換到運(yùn)行狀態(tài)，這也是軟起動(dòng)器的一個(gè)難點(diǎn)，如何選準(zhǔn)旁路點(diǎn)非常重要。旁路點(diǎn)早了，電流沖擊非常大，即使在低壓條件下，也會(huì)造成三相電源中斷路器跳閘，甚至?xí)p壞斷路器。高壓條件下危害更大。旁路點(diǎn)遲了，電機(jī)抖動(dòng)得厲害，影響負(fù)載正常工作。因此，旁路信號(hào)的硬件檢測電路必須非常精確，并且程序處理也要恰到好處。綜上所述，盡管低壓軟起動(dòng)器和高壓軟起動(dòng)器的基本原理一致，但高壓軟起動(dòng)器存在的諸多技術(shù)難題，使得在低壓軟起動(dòng)器遍地開花的情況下，高壓軟起動(dòng)器的成熟產(chǎn)品并不多見。 </p><p style="text-indent:25px">電機(jī)軟啟動(dòng)器的主接線有三種方法主要是在線型、旁路型、內(nèi)置旁路型。 1.在線型：一切軟發(fā)動(dòng)器的控制器都有電動(dòng)機(jī)過載保護(hù)，當(dāng)軟啟動(dòng)器在線運(yùn)行時(shí)對(duì)電機(jī)進(jìn)行過載保護(hù)，不要加裝熱過載繼電器。由于經(jīng)過可控硅后的電流諧波電流非常大，所以不能加裝電子式熱過載繼電器，否則會(huì)使系統(tǒng)不能正常的工作。 2.旁路型：對(duì)于軟啟動(dòng)器上口的接觸器的作用和在線運(yùn)行方式下作用相同的情況下不能再重復(fù)。這邊注意的熱繼電器，把它安方在旁路接觸器的下口，不通電流，尤其是電子熱繼電器，由于經(jīng)過軟啟動(dòng)器后電流諧波很大能干擾電子熱繼電器誤動(dòng)作而使電機(jī)停車。 3.內(nèi)置旁路型：它的主接線和在線型的大致相同，它的主要優(yōu)點(diǎn)是可控硅的短時(shí)工作沒必要安裝快速熔斷器。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
