它的主要構(gòu)成是串接于電源與被控電機之間的三相反并聯(lián)閘管及其電子控制電路。運用不同的方法，控制三相反并聯(lián)閘管的導(dǎo)通角，使被控電機的輸入電壓按不同的要求而變化，就可實現(xiàn)不同的功能。變頻器（Variable-frequencyDrive，VFD）是應(yīng)用變頻技術(shù)與微電子技術(shù)，通過改變電機工作電源頻率方式來控制交流電動機的電力控制設(shè)備。變頻器主要由整流（交流變直流）、濾波、逆變（直流變交流）、制動單元、驅(qū)動單元、檢測單元微處理單元等組成。變頻器靠內(nèi)部IGBT的開斷來調(diào)整輸出電源的電壓和頻率，根據(jù)電機的實際需要來提供其所需要的電源電壓，進而達到節(jié)能、調(diào)速的目的，另外，變頻器還有很多的保護功能，如過流、過壓、過載保護等等。隨著工業(yè)自動化程度的不斷提高，變頻器也得到了非常的應(yīng)用。軟啟動器和變頻器是兩種完全不同用途的產(chǎn)品。變頻器是用于需要調(diào)速的地方，其輸出不但改變電壓而且同時改變頻率；軟啟動器實際上是個調(diào)壓器，用于電機起動時，輸出只改變電壓并沒有改變頻率。變頻器具備所有軟起動器功能，但它的價格比軟啟動器貴得多，結(jié)構(gòu)也復(fù)雜得多。軟啟動器只是改變電源電壓，相當于降壓起動器。變頻器要比軟啟動器復(fù)雜得多，價格也貴得多。變頻器也有軟啟動功能。 </p><p style="text-indent:25px">為什么現(xiàn)在的電機比以前更容易燒毀？由于絕緣技術(shù)的不斷發(fā)展，在電機的設(shè)計上既要求增加出力，又要求減小體積，使新型電機的熱容量越來越小，過負荷能力越來越弱；再由于生產(chǎn)自動化程度的提高，要求電機經(jīng)常運行在頻繁的起動、制動、正反轉(zhuǎn)以及變負荷等多種方式，對電機保護裝置提出了更高的要求。另外，電機的應(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><div

想的電機保護器？理想的電機保護器不是功能**多，也不是所謂**技術(shù)的，而是應(yīng)該滿足現(xiàn)場實際需求，做到經(jīng)濟性和可靠性的統(tǒng)一，具有較高的性能價格比。根據(jù)現(xiàn)場的實際情況合理地選擇保護器的種類、功能，湖南長沙軟啟動器同時考慮保護器安裝、調(diào)整、使用簡單方便，更重要的是要選擇高質(zhì)量的保護器。水泵啟動方式有直接啟動，降壓啟動，軟啟動和變頻啟動四種，直接啟動一般適合小功率的電機，我們一般只在15kw以下的泵上使用，價格便宜；降壓啟動是星—三角轉(zhuǎn)換啟動，就是啟動是分兩次加速才達到額定轉(zhuǎn)速的，一般在，價格適中；軟啟動是逐漸增加到額定轉(zhuǎn)速的，對泵的沖擊很小，價格比較高，一般是降壓啟動的3倍；高級的是變頻啟動，除了有軟啟動的優(yōu)點外，還可以設(shè)定在任意轉(zhuǎn)速工作，對節(jié)能降耗有效果。在關(guān)閉泵出口閥，打開泵進口閥，并能確保水泵“自灌”(液位高于泵的進口的管道條件下，水泵的啟動程序是：啟動電機，待電機正常運行時，緩緩打開出口閥，使電流慢慢加大。但在無人操作(開閥)，又是自動啟泵，且管道直徑與長度大(管道內(nèi)的水質(zhì)量會很大)，如電機快速啟動，要迅速推動大質(zhì)量的水加速(如同火車要很快加速)，會使電機啟動電流很大。淄博科恩軟啟動器銷售價格</p><p style="text-indent:25px">淄博科恩軟啟動器銷售價格</p><p>污水處理廠該如何選擇軟啟動器。污水處理廠一般使用軟啟動器的場景是水泵上，那么該如何為其選擇軟啟動器呢。首先我們需要考慮到，污水處理廠其實是有兩種水泵的，一種是清水泵，一種是污水泵。首先清水泵。因為只是常規(guī)的清水泵，所以我們只要選擇常規(guī)對應(yīng)功率的軟啟動器即可。并沒有太多需要注意的。對應(yīng)艾克威爾的品牌，我們推薦使用mg3系列軟啟動器，可以很好的解決水錘效應(yīng)。其次則是污水泵。污水泵和清水泵不同，有些需要處理的污水因為雜志較多，甚至可能出現(xiàn)淤泥狀，這對電機本身也是增大了符合，瞬間啟動電流會比常規(guī)同等功率的電機大很多。那么這個時候我們就需要考慮，把軟啟動器加大一檔，甚至根據(jù)現(xiàn)場的情況，我們可以考慮加大兩檔處理。對應(yīng)艾克威爾的軟啟動器，我們推薦使用Mg6系列軟啟動器，加大一檔話，則是37KW的電機可以選用45KW的軟啟動器。淄博科恩軟啟動器銷售價格</p><p
