軟啟動柜發(fā)生故障有哪些原因造成的

大功率電機在工業(yè)中的應(yīng)用也非常廣泛電機直啟會帶給電網(wǎng)極大的影響，也會使電機本身及機械產(chǎn)生傷害，因此就需要實現(xiàn)軟啟動。軟啟動就是采用軟件控制方式來平滑啟動電動機，如今常見的有兩種方式，變頻恒轉(zhuǎn)矩限流啟動，以及智能軟啟動。有關(guān)這二者我們也曾做過對比，變頻器可實現(xiàn)的功能多，軟啟動柜使用成本低，在只需要實現(xiàn)軟起的條件下就可以起動。
任何設(shè)備的使用都可能有故障發(fā)生，或設(shè)備本身的缺陷、或使用方式錯誤、或生產(chǎn)技術(shù)不到位，對于軟啟動柜來說，該技術(shù)還在不斷的發(fā)展中，如今常用的旁路式軟啟動柜就是我們在線式設(shè)備上的創(chuàng)新，那么導致軟啟動柜使用中發(fā)生故障的，有可能是使用方式不當造成的。軟啟動柜的使用需要串聯(lián)在電機與電源間，在實際應(yīng)用中常出現(xiàn)電機不能啟動的情況，主要有兩種原因?qū)е?。一是軟啟動柜設(shè)備中應(yīng)用的六只可控硅的其中一只觸發(fā)不可靠或是不導通，此時一相電路通過的是半波直流，電動機的兩相繞組通過的直流對電動機起到了制動作用，不僅電機起不來，嚴重的還會燒毀電機和可控硅。還有一個原因可能是設(shè)備啟動參數(shù)不合理，這種情況多發(fā)生在調(diào)試階段，一般來說使用方在受到設(shè)備時已經(jīng)經(jīng)過調(diào)試，所以不太可能出現(xiàn)這種情況。
使用中的軟啟動柜發(fā)生故障，還有可能是內(nèi)部插件接觸不良導致。這個問題如果使用廠家有定期對設(shè)備進行養(yǎng)護應(yīng)該是很容易就能發(fā)現(xiàn)的，但是因為對設(shè)備的不了解，所以也經(jīng)常會發(fā)生。對于擁有15年經(jīng)驗豐富的電氣設(shè)備廠家來說，我們對客戶的設(shè)備維修以及后期故障咨詢都會負責，如果發(fā)現(xiàn)有類似情況可直接聯(lián)系我們進行處理。
當然，軟啟動柜結(jié)構(gòu)簡單只是相對的，其原理與故障我們廠家明白，使用客戶可能不太清楚。在使用中設(shè)備可能發(fā)生的故障有很多，可控硅燒穿、設(shè)備誤動作、控制器損毀……所以在使用時還是建議使用方依照產(chǎn)品使用說明，如果設(shè)備發(fā)生故障及時聯(lián)系我們進行維修。
