高壓軟起動(dòng)器對信號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。所以對檢測到的信號不僅要進(jìn)行硬件濾波，也要進(jìn)行軟件濾波，去掉干擾信號。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。科恩電氣交通便利，地理位置優(yōu)越。淄博科恩軟啟動(dòng)器經(jīng)銷商</p><p

軟啟動(dòng)的好處1．降低電動(dòng)機(jī)的起動(dòng)電流，減少配電容量，避免增容投資；2．減少起動(dòng)應(yīng)力，延長電動(dòng)機(jī)及相關(guān)設(shè)備的使用壽命；3．平穩(wěn)的起動(dòng)和軟停車避免了傳統(tǒng)起動(dòng)設(shè)備的喘振問題、水錘效應(yīng)；4．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，改善工藝；5．完善可靠的保護(hù)功能，更有效的保護(hù)電動(dòng)機(jī)及相關(guān)設(shè)備的安全；軟啟動(dòng)器的工作原理軟起動(dòng)主要由串接于電源與被控電動(dòng)機(jī)之間三對反并聯(lián)晶閘管調(diào)壓電路構(gòu)成。現(xiàn)代軟啟動(dòng)器基本上都采用了電力電子技術(shù)和微機(jī)控制技術(shù)，以單片微機(jī)作為**控制器控制來完成測量及各種控制算法。因此，山東濟(jì)寧軟啟動(dòng)器具備了很強(qiáng)的功能和靈活性。整個(gè)起動(dòng)過程是數(shù)字化程序軟件控制下自動(dòng)進(jìn)行。利用三對晶閘管的電子開關(guān)特性，通過MCU或單片機(jī)控制其觸發(fā)脈沖的遲早來改變觸發(fā)角的大小。而改變觸發(fā)導(dǎo)通角的大小，又改變了晶閘管的導(dǎo)通時(shí)間，較終改變定子繞組的三相電壓的大小。主要元件1、晶閘管：每相一對反并聯(lián)晶閘管，這是主要的功率元件，也是軟啟動(dòng)器的主要成本之一，國內(nèi)做反并聯(lián)晶閘管的廠家有很多，從便宜的到貴的都有，質(zhì)量更是參差不齊。2、控制主板：基本上每個(gè)廠家都有自己開發(fā)的主板，市場上也有很多通用主板。淄博科恩軟啟動(dòng)器經(jīng)銷商</p><p
