style="text-indent:25px">軟啟動(dòng)是指電機(jī)的電壓由零慢慢上升到額定電壓，這樣電機(jī)在啟動(dòng)的過程中啟動(dòng)電流，由過去的過載沖擊不可控電流變成了可控制的電流，并且可以根據(jù)需要來對(duì)電機(jī)啟動(dòng)器進(jìn)行電流的大小調(diào)整。如果直接啟動(dòng)電機(jī)軟啟動(dòng)器對(duì)軟啟動(dòng)器有什么樣的危害呢？ 1.會(huì)引起電網(wǎng)電壓的波動(dòng) 交流電動(dòng)機(jī)在全壓下直接啟動(dòng)，起動(dòng)電流會(huì)達(dá)到額定電流的4到7倍，如果電機(jī)的容量相對(duì)來說比較大時(shí)，啟動(dòng)電流會(huì)引起電網(wǎng)電壓的急劇下降，同時(shí)還會(huì)影響電網(wǎng)和其他設(shè)備的正常運(yùn)行。 2，淄博科恩軟啟動(dòng)器廠家推薦.對(duì)電網(wǎng)的影響對(duì)于電網(wǎng)的影響會(huì)表現(xiàn)在兩個(gè)方面（1）超大型的電機(jī)直接啟動(dòng)，大電流對(duì)電網(wǎng)的沖擊相當(dāng)于三相短路對(duì)電網(wǎng)的沖擊，淄博科恩軟啟動(dòng)器廠家推薦，這時(shí)會(huì)常常應(yīng)發(fā)發(fā)動(dòng)機(jī)的振蕩，使電網(wǎng)失去穩(wěn)定。（2）起動(dòng)電流中含有大量的高次諧波，會(huì)與電網(wǎng)電路參數(shù)引起高頻諧振，造成繼電保護(hù)誤動(dòng)作、自動(dòng)控制失靈等故障，淄博科恩軟啟動(dòng)器廠家推薦。 3.傷害電機(jī)絕緣（1）大電流所產(chǎn)生的焦耳熱反復(fù)作用于導(dǎo)線外絕緣，使絕緣加速老化、壽命降低。（2）大電流產(chǎn)生的機(jī)械力使導(dǎo)線相互摩擦，降低絕緣壽命。（3）高壓開關(guān)合閘時(shí)觸頭的抖動(dòng)現(xiàn)象會(huì)在電機(jī)定子繞組上產(chǎn)生操作過電壓，有時(shí)會(huì)達(dá)到外加電壓的5倍以上，這樣高的過電壓會(huì)對(duì)電機(jī)絕緣造成極大。淄博科恩軟啟動(dòng)器廠家推薦</p><div

style="text-indent:25px">淄博科恩軟啟動(dòng)器廠家推薦</p><p> 軟起動(dòng)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(dòng)過程,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)器廠家推薦</p><p
