晶閘管導(dǎo)通條件為：加正向電壓且門極有觸發(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。晶閘管在工作過程中，它的陽極(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.晶閘管承受反向陽極電壓時(shí)，不管門極承受何種電壓，晶閘管都處于反向阻斷狀態(tài)。2.晶閘管承受正向陽極電壓時(shí)，*在門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極電壓，不論門極電壓如何，晶閘管保持導(dǎo)通，即晶閘管導(dǎo)通后，門極失去作用。門極只起觸發(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。 </p><p> 軟啟動(dòng)器，應(yīng)用先進(jìn)的軟件設(shè)計(jì)方法和的硬件技術(shù)，采用晶閘管相移技術(shù)，使加到電動(dòng)機(jī)上的電壓按某一規(guī)律慢慢達(dá)到全電壓，通過設(shè)置適當(dāng)?shù)目刂茀?shù)，可以使電動(dòng)機(jī)的轉(zhuǎn)矩和電流與負(fù)載要求得到較好的匹配。同時(shí)，通過軟件與硬件的配合，對(duì)軟啟動(dòng)器本身、電動(dòng)機(jī)、負(fù)載提供的保護(hù)。一般來講，電動(dòng)機(jī)功率的選擇總是大于比較大負(fù)載要求，其結(jié)果是電動(dòng)機(jī)很少在額定功率下運(yùn)行，經(jīng)常處于輕載或變載的情況，能量嚴(yán)重浪費(fèi)。軟啟動(dòng)在運(yùn)行時(shí)，首先保持輸出額定電壓，以保證電動(dòng)機(jī)和負(fù)載在加速后進(jìn)入穩(wěn)定狀態(tài)；保持一段很短時(shí)間之后，自動(dòng)進(jìn)入節(jié)電運(yùn)行階段。其獨(dú)有的節(jié)電控制軟件自動(dòng)負(fù)載變化，通過不斷對(duì)電流和功率因數(shù)的綜合計(jì)算，進(jìn)行實(shí)時(shí)調(diào)節(jié)、更新觸發(fā)角，控制輸出電壓，降低勵(lì)磁電流，提高功率因數(shù)，實(shí)現(xiàn)節(jié)電。

style="text-indent:25px">電機(jī)軟啟動(dòng)器常見故障：目前國(guó)內(nèi)的軟起動(dòng)器生產(chǎn)廠家很多，大都是旁路型的電機(jī)軟啟動(dòng)器，產(chǎn)品的可靠性與世界**品牌相比差距越來越小，下面我們來總結(jié)一下電機(jī)軟啟動(dòng)器常見故障有哪些？1.電動(dòng)機(jī)起不來：電動(dòng)機(jī)起不來的原因可能是六只可控硅的其中一只觸發(fā)不可靠或是不導(dǎo)通或者是啟動(dòng)參數(shù)或啟動(dòng)曲線不合適造成電機(jī)起不來。 2.可控硅燒毀：可控硅擊穿或，此類故障不分國(guó)內(nèi)外品牌，因廠家而易，但這類故障率低，而且主要問題出現(xiàn)在餅式可控硅的安裝工藝上?！?3.控制器燒損：控制器燒損這類故障主要是控制器的電源和觸發(fā)電路以及輸入電路三部分容易燒毀。 4.軟啟動(dòng)器誤動(dòng)作：電動(dòng)機(jī)在運(yùn)行的裝態(tài)下因電機(jī)軟起動(dòng)器受干擾而停機(jī)在停止?fàn)顟B(tài)下其中原因可能是產(chǎn)品的質(zhì)量問題或是線路布局的問題。淄博科恩軟啟動(dòng)器值得信賴</p><p

從長(zhǎng)期來看：變頻軟起將會(huì)成為軟起動(dòng)器（西馳分級(jí)變頻軟起動(dòng)器）的主流。各種形式的降壓軟起動(dòng)將與星三角起動(dòng)等技術(shù)一起歸并為傳統(tǒng)的起動(dòng)技術(shù)。隨著變頻器價(jià)格的逐漸下降，可靠性的進(jìn)一步提高，也隨著技術(shù)人員水平的提高，**為軟起動(dòng)而選用變頻器將不再會(huì)被人們認(rèn)為是一種。變頻軟起動(dòng)勝出的根本原因是：它可以在限流（起動(dòng)電流不超過電機(jī)額定電流值）的同時(shí)獲得大的起動(dòng)轉(zhuǎn)矩，可以實(shí)現(xiàn)包括軟停止在內(nèi)的各種起動(dòng)功能。對(duì)于**為軟起動(dòng)而制作的變頻器而言，應(yīng)在起動(dòng)完成后使變頻器脫電，使電動(dòng)機(jī)直掛電網(wǎng)。這樣做的目的是節(jié)能，消除無謂的損耗。這種操作應(yīng)該在安全的不引起電流沖擊的條件下完成，或者叫做軟切換。軟切換的可能步驟是“先脫（電）后掛（網(wǎng)）”或“先掛后脫”，軟切換應(yīng)該在基本上不增加硬件（例如軟切換電抗器）的條件下主要靠軟件完成。淄博科恩軟啟動(dòng)器值得信賴</p><p
