style="text-indent:25px">大家都知道在軟啟動器中都會有一個(gè)R型變壓器，R型變壓器主要是采用取向性高磁導(dǎo)率硅鋼帶制成的，同時(shí)具有體積小、重量輕、效率高、漏磁小等特點(diǎn)得到了普遍的應(yīng)用。軟啟動器在控制電路時(shí)需要使用低壓直電流，但是又不能直接使用開關(guān)電源，所以在使用時(shí)需要一種隔離電源變壓器，于是軟啟動器就看上了R型變壓器了。軟啟動器選擇R型變壓器也不是沒有道理的，下面來說一下使用R型變壓器的好處。 1.效率高 R型變壓器鐵芯無切割，損失小，并且使用***的材料和緊湊的結(jié)構(gòu)，可以把鐵芯與繞組之間的距離降底，這樣效率可以達(dá)到百分之90以上。 2.無噪音由于R型變壓器是使用***低損耗的材料，并且具有均勻圓形截面和連續(xù)的繞線，淄博科恩軟啟動器推薦企業(yè)，電阻的損耗和產(chǎn)熱都非常的低，磁致伸縮應(yīng)力很容易被吸收，因此在使用過程中不會發(fā)出噪音來。 3，淄博科恩軟啟動器推薦企業(yè).漏磁小 R型變壓器的鐵芯都是繞線極勻衡，因此漏磁是非常小的，在使用過程中無需采取防范措施來防止漏磁的現(xiàn)象。 4.符合安全的標(biāo)準(zhǔn) 由于它的獨(dú)特設(shè)計(jì)，淄博科恩軟啟動器推薦企業(yè)，將初級與次級的骨架分開，并且具有良好的絕緣性。由于阻燃材料制成的互相分離的骨架這樣可以滿足我國的安全標(biāo)準(zhǔn)淄博科恩軟啟動器推薦企業(yè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">淄博科恩軟啟動器推薦企業(yè)</p><p> 軟起動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,完成起動過程,這是軟起動器的基本原理。目前在低壓軟起動器市場,產(chǎn)品繁多,但是高壓軟起動器產(chǎn)品還是比較少。高壓軟起動器與低壓軟起動器基本原理一樣，但是高壓軟起動器與低壓軟起動器相比,有些地方存在著其特殊性：1.高壓軟起動器在高壓環(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)。高壓軟起動器組成電氣柜時(shí),電氣元器件的布局以及與高壓軟起動器與其它電氣設(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,而不是低壓軟起動器的普通單片機(jī)芯。低壓軟起動器主回路由三組反并聯(lián)的晶閘管組成。而在高壓軟起動器中,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．高壓軟起動器的工作環(huán)境容易受到各種電磁干擾。淄博科恩軟啟動器推薦企業(yè)</p><p
