軟起動(dòng)器主回路采用晶閘管,通過(guò)逐步改變晶閘管的導(dǎo)通角來(lái)抬升電壓,完成起動(dòng)過(guò)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(méi)有完全一致。晶閘管參數(shù)的不一致，會(huì)導(dǎo)致晶閘管開(kāi)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)器廠家報(bào)價(jià)以客戶至上為理念，為客戶提供咨詢服務(wù)。</p><div

晶閘管導(dǎo)通條件為：加正向電壓且門(mén)極有觸發(fā)電流;其派生器件有：快速晶閘管，雙向晶閘管，逆導(dǎo)晶閘管，光控晶閘管等。它是一種大功率開(kāi)關(guān)型半導(dǎo)體器件，在電路中用文字符號(hào)為“V”、“VT表示。晶閘管在工作過(guò)程中，它的陽(yáng)極(A)和陰極(K)與電源和負(fù)載連接，組成晶閘管的主電路，晶閘管的門(mén)極G和陰極K與控制晶閘管的裝置連接，組成晶閘管的控制電路。高壓晶閘管軟啟動(dòng)器為半控型電力電子器件，它的工作條件如下：1.晶閘管承受反向陽(yáng)極電壓時(shí)，不管門(mén)極承受何種電壓，晶閘管都處于反向阻斷狀態(tài)。2.晶閘管承受正向陽(yáng)極電壓時(shí)，*在門(mén)極承受正向電壓的情況下晶閘管才導(dǎo)通。這時(shí)晶閘管處于正向?qū)顟B(tài)，這就是晶閘管的閘流特性，即可控特性。3.晶閘管在導(dǎo)通情況下，只要有一定的正向陽(yáng)極電壓，不論門(mén)極電壓如何，晶閘管保持導(dǎo)通，即晶閘管導(dǎo)通后，門(mén)極失去作用。門(mén)極只起觸發(fā)作用。4.晶閘管在導(dǎo)通情況下，當(dāng)主回路電壓(或電流)減小到接近于零時(shí)，晶閘管關(guān)斷。

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(lái)很大沖擊，對(duì)我們電機(jī)本身也會(huì)帶來(lái)很大傷害，嚴(yán)重縮短使用壽命，甚至?xí)陔妷弘娏鬟^(guò)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(lái)說(shuō)，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(lái)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(jiàn)的風(fēng)機(jī)、水泵這種類(lèi)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(lái)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(lái)很大，可能發(fā)生的危險(xiǎn)。科恩電氣產(chǎn)品遠(yuǎn)銷(xiāo)中國(guó)臺(tái)灣、韓國(guó)、日本、越南、印度、馬來(lái)西亞、新加坡、俄羅斯等國(guó)家。</p><div
