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。 </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。

現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號(hào)的軟啟動(dòng)器來選用軟啟動(dòng)器軟啟動(dòng)器選型：目前市場(chǎng)上常見的軟啟動(dòng)器有旁路型軟啟動(dòng)器、無旁路型軟啟動(dòng)器、節(jié)能型軟啟動(dòng)器等。下面我們來一一講它們的功能：旁路型軟啟動(dòng)器：在電動(dòng)機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí)，用旁路接觸器取代已完成任務(wù)的軟啟動(dòng)器，降低晶閘管的熱損耗，提高其工作效率。也可以用一臺(tái)軟啟動(dòng)器去啟動(dòng)多臺(tái)電動(dòng)機(jī)。無旁路型軟啟動(dòng)器：晶閘管處于全導(dǎo)通狀態(tài)，電動(dòng)機(jī)工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時(shí)重復(fù)工作的電動(dòng)機(jī)。節(jié)能型軟啟動(dòng)器：當(dāng)電動(dòng)機(jī)負(fù)荷較輕時(shí)，軟啟動(dòng)器自動(dòng)降低施加于電動(dòng)機(jī)定子上的電壓，減少電動(dòng)機(jī)電流勵(lì)磁分量，提高電動(dòng)機(jī)功率因數(shù)。軟啟動(dòng)器如何選規(guī)格?根據(jù)電動(dòng)機(jī)的標(biāo)稱功率，電流負(fù)載性質(zhì)選擇啟動(dòng)器，一般軟啟動(dòng)器容量稍大于電動(dòng)機(jī)工作電流，還應(yīng)考慮保護(hù)作用是否完備，例如：缺相保護(hù)、短路保護(hù)、過載保護(hù)、逆序保護(hù)、過壓保護(hù)、欠壓保護(hù)等。淄博科恩軟啟動(dòng)器供應(yīng)</p><p
