style="text-indent:25px">電機(jī)軟啟動器是主要采用電力電子技術(shù)和微處理技術(shù)以及現(xiàn)代控制理論而設(shè)計(jì)生產(chǎn)的具有先進(jìn)水平的新型啟動設(shè)備，電機(jī)軟啟動器主要具有抗干擾功能、可靠性高、多重保護(hù)功能等特點(diǎn)，根據(jù)這些特點(diǎn)電機(jī)軟啟動器得到了普遍應(yīng)用，主要應(yīng)用于風(fēng)機(jī)、水泵、輸送類及壓縮機(jī)等領(lǐng)域。電機(jī)軟啟動器是一種集電機(jī)軟起動、軟停車、輕載節(jié)能等多功能于一體的新型電機(jī)控制裝備。軟啟器主要是采用三相反并聯(lián)晶閘管作為調(diào)壓器將它連接在電源和電動機(jī)定子之間，使軟啟動器啟動電動機(jī)時，晶閘管所輸出的電壓逐漸增加，同時電動機(jī)也逐漸加速，直到晶閘管全部疏通，電動機(jī)工作在額定電壓的機(jī)械特性上，才能實(shí)現(xiàn)平滑啟動，降低啟動電流，來避免啟動電流過大而產(chǎn)生跳閘的現(xiàn)象。待電機(jī)達(dá)到額定轉(zhuǎn)數(shù)時，啟動過程結(jié)束，軟啟動器自動用旁路所接觸器來取代晶閘管，為電動機(jī)正常運(yùn)轉(zhuǎn)提供額定電壓，以降低晶閘管的熱損耗同時還延長軟啟動器的使用壽命，提高其工作效率。同時電氣軟啟動器還提供了軟停車的功能，軟停車與軟啟動過程真好相反，電壓逐漸降低，轉(zhuǎn)數(shù)逐漸下降到零，避免自由停車引起的轉(zhuǎn)矩沖擊。淄博科恩軟啟動器報價</p><div

軟起動器具有軟起動、軟停止、泵控制功能、定時低速運(yùn)行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動力設(shè)備控制中具有傳統(tǒng)降壓起動器不可比擬的優(yōu)越性。三相異步電動機(jī)有很多優(yōu)點(diǎn)，但也有兩個致命的弱點(diǎn)：一是啟動性能差；二是調(diào)速性能差。隨著電力半導(dǎo)體技術(shù)的發(fā)展以及大功率晶體管在工業(yè)控制領(lǐng)域里的應(yīng)用，有兩個典型的產(chǎn)品改善了異步電動機(jī)這兩個弱點(diǎn)，一是變頻器，二是軟啟動器。變頻器改善異步電動機(jī)的調(diào)速性能；軟起動在起動時間ts內(nèi)，電機(jī)的端電壓從設(shè)定的初始值逐漸增至滿壓，電機(jī)平滑、無級地加速。同時ts可調(diào)節(jié)(通常在60s之間),這有利于與低壓斷路器之間的配合，防止低壓斷路器的瞬時脫扣器在電機(jī)起動時誤跳閘。過載保護(hù)功能一般電機(jī)的過載保護(hù)是通過熱元件來實(shí)現(xiàn)的，熱元件在電動機(jī)起動過程中很難避開電機(jī)的起動電流而產(chǎn)生誤動作。為避免誤動，用戶常加大熱元件的動作電流，因而使得過載保護(hù)的靈敏度不夠，使過載保護(hù)形同虛設(shè)。而軟起動器內(nèi)置的過載保護(hù)功能是根據(jù)起動負(fù)荷的輕重(即起動時間的長短)來選擇不同的脫扣特性曲線，以避免在起動過程中誤跳。由于它的過載保護(hù)是可編程的，軟啟動器廠家從而為用戶提供了更大的靈活性。 </p><p> 鼠籠型異步電動機(jī)因價格低廉，性能可靠，在工業(yè)領(lǐng)域得到廣泛應(yīng)用。隨著近年來各種新技術(shù)、新工藝的出現(xiàn)，<span style="font-size:12px;">對鼠籠型異步電動機(jī)的起動和停止提出了新的要求，而軟起動器的出現(xiàn)滿足了這一要求。軟啟動控制器是一種</span><span

Starter。它的主要構(gòu)成是串接于電源與被控電機(jī)之間的三相反并聯(lián)閘管及其電子控制電路。運(yùn)用不同</span><span style="font-size:12px;">的方法，控制三相反并聯(lián)閘管的導(dǎo)通角，使被控電機(jī)的輸入電壓按不同的要求而變化，就可實(shí)現(xiàn)不同的功能。</span> </p><div

軟起動器的日常維修與檢查平時注意檢查軟起動器的環(huán)境條件防止在超過其允許的環(huán)境條件下運(yùn)行。注意檢查軟起動器周圍是否有妨礙其通風(fēng)散熱的物體確保軟起動器四周有足夠的空間大于150mm定期檢查配電線端子是否松動柜內(nèi)元器件有否過熱、變色、焦臭味等異?，F(xiàn)象。定期清掃灰塵以免影響散熱，防止晶閘管因溫升過高而損壞同時也可避免因積塵引起的漏電和短路。清掃灰塵可用干燥的毛刷進(jìn)行也可用于皮老虎吹和吸塵器吸。對于大塊污垢可用絕緣棒去除。若有條件可用。平時注意觀察風(fēng)機(jī)的運(yùn)行情況一旦發(fā)現(xiàn)風(fēng)機(jī)轉(zhuǎn)速慢或異常應(yīng)及時修理如油垢、積塵加潤滑油更換損壞或變質(zhì)的電容器。對損壞的風(fēng)機(jī)要及時更換。如果在沒有風(fēng)機(jī)的情況下使用軟起動器將會損壞晶閘管。如果軟起動器使用環(huán)境較潮濕或易結(jié)露應(yīng)經(jīng)常用紅外燈泡或電吹風(fēng)烘干驅(qū)除潮氣以避免漏電或短路的發(fā)生。淄博科恩軟啟動器報價</p><p

交流感應(yīng)電動機(jī)在直接啟動時存在著兩點(diǎn)缺點(diǎn)，首先它的啟動電流可高達(dá)額定電流的5－7倍，這要求電網(wǎng)寬裕量比較大，而且降低電器控制設(shè)備的使用壽命，增加維護(hù)成本；其次，啟動轉(zhuǎn)矩可達(dá)正常轉(zhuǎn)矩的兩倍，這會對負(fù)載產(chǎn)生沖擊，增加傳動部件的磨損和額外維護(hù)。基于以上原因，產(chǎn)生交流感應(yīng)電動機(jī)降壓啟動設(shè)備。傳統(tǒng)的降壓啟動方法有Y/△啟動和自耦變壓器降壓啟動兩種，每種都有各自的缺點(diǎn)。電動機(jī)用Y/△啟動設(shè)備啟動時，在切換瞬間會出現(xiàn)很高的電流尖峰，產(chǎn)生破壞性的動態(tài)轉(zhuǎn)矩，其引起的機(jī)械振動對電動機(jī)轉(zhuǎn)子、軸連接器、中間齒輪以及負(fù)載等都非常有害；自耦變壓器降壓啟動設(shè)備體積龐大、成本高，而且還存在與負(fù)載匹配的電動機(jī)轉(zhuǎn)矩很難控制等缺點(diǎn)。由于傳統(tǒng)的降壓啟動設(shè)備存在諸多缺點(diǎn)，這才出現(xiàn)了電子式數(shù)字軟啟動裝置。淄博科恩軟啟動器報價</p><p
