style="text-indent:25px">電機(jī)軟啟動器常見故障：目前國內(nèi)的軟起動器生產(chǎn)廠家很多，大都是旁路型的電機(jī)軟啟動器，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)軟啟動器常見故障有哪些？1.電動機(jī)起不來：電動機(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)通或者是啟動參數(shù)或啟動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.軟啟動器誤動作：電動機(jī)在運(yùn)行的裝態(tài)下因電機(jī)軟起動器受干擾而停機(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。淄博科恩軟啟動器全國發(fā)貨</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">為什么現(xiàn)在的電機(jī)比以前更容易燒毀？由于絕緣技術(shù)的不斷發(fā)展，在電機(jī)的設(shè)計上既要求增加出力，又要求減小體積，使新型電機(jī)的熱容量越來越小，過負(fù)荷能力越來越弱；再由于生產(chǎn)自動化程度的提高，要求電機(jī)經(jīng)常運(yùn)行在頻繁的起動、制動、正反轉(zhuǎn)以及變負(fù)荷等多種方式，對電機(jī)保護(hù)裝置提出了更高的要求。另外，電機(jī)的應(yīng)用面更廣，常工作于環(huán)境極為惡劣的場合，如潮濕、高溫、多塵、腐蝕等場合。所有這些，造成了現(xiàn)在的電機(jī)比過去更容易損壞，尤其是過載、短路、缺相、掃膛等故障出現(xiàn)頻率比較高。</p><p style="text-indent:25px">電機(jī)軟啟動器是一種集電機(jī)軟啟動、軟停車、輕載節(jié)能等多功能于一體的新穎電機(jī)裝置，可普遍應(yīng)用到風(fēng)機(jī)、水泵、輸送類及壓縮機(jī)等負(fù)載。 1.電機(jī)軟啟動器本身是沒有短路保護(hù)的，為了保護(hù)其中的晶閘管應(yīng)該采用快速熔斷器，因此我們在要根據(jù)軟啟動器的額定電流來選擇快速熔斷器，因為低壓斷路器開斷時間較長(約為0.1S)，所以不宜用于晶閘管的保護(hù)。 2.當(dāng)我們在使用電機(jī)軟啟動器時，使電動機(jī)制動停機(jī)，主要的原因是由于晶閘管不導(dǎo)通，所以我們在檢修電動機(jī)或線路時，必須要先斷開供電電源，這樣可以使軟啟動器與電源之間增設(shè)斷路器 3.電機(jī)軟啟動器在內(nèi)部設(shè)置了多種保護(hù)功能，在具體使用時要根據(jù)實際的需要，通過編程來選擇保護(hù)功能或者使某些保護(hù)功能失效，例如：突然斷電時過負(fù)載造成的損失會更大，其過負(fù)載保護(hù)應(yīng)作用與信號而不應(yīng)用于切斷電路。 4.當(dāng)電機(jī)軟啟動器功率較大或者臺數(shù)較多時，產(chǎn)生的高次諧波會對電網(wǎng)所造成不良影響，并且對電子設(shè)備產(chǎn)生干擾，當(dāng)電動機(jī)平穩(wěn)啟動到正常轉(zhuǎn)速時，旁路接觸器閉合，把軟啟動器短接，在啟動完成之后，大功率晶閘管不在工作，從而消去除高次諧波對電網(wǎng)以及電子設(shè)備的干擾。</p><div

style="text-indent:25px">電機(jī)軟啟動器一般以大功率雙向晶閘管構(gòu)成三相交流調(diào)壓電路，以微處理器及信號采集、保護(hù)環(huán)節(jié)構(gòu)成控制器，通過控制晶閘管的觸發(fā)角，調(diào)節(jié)晶閘管調(diào)壓電路的輸出電壓，實現(xiàn)電動機(jī)的無觸點降壓軟啟動、軟停車和空載、輕載的節(jié)能及保護(hù)功能。為此，通過對軟啟動方式與傳統(tǒng)的啟動方式進(jìn)行比較，來分析軟啟動器的特性。軟啟動器，其實是一種擁有電機(jī)軟起動、軟停車、輕載節(jié)能以及多種保護(hù)功能一身的電機(jī)控制裝置。主要是串接在電源與被控電機(jī)之間的三相反并聯(lián)閘管及其電子控制電路。通過控制三相反并聯(lián)閘管的導(dǎo)通角，讓被控電機(jī)的輸入電壓會根據(jù)不同的要求而變化，實現(xiàn)各種功能。軟啟動器是用在要降壓啟動和停止的地方，這時的電機(jī)轉(zhuǎn)速不變；但是科恩變頻器主要是用來調(diào)速，恒壓的地方，轉(zhuǎn)速由頻率決定。淄博科恩軟啟動器全國發(fā)貨</p><p
