電機絕緣電阻和接地電阻阻值(電動(dòng)機相對地絕緣電阻多大為合格)

絕緣電阻是對電機繞組部分的要求，即電機帶電部分相對于其他非帶電部分的絕緣性能。標準根據電機額定電壓和冷熱狀態(tài)的不同，規定了絕緣電阻的小值，也...

低壓無(wú)功補償柜接線(xiàn)原理說(shuō)明圖(無(wú)功補償裝置接線(xiàn)圖)

無(wú)功補償裝置靜止進(jìn)相器的接線(xiàn)說(shuō)明靜止進(jìn)相器不僅可以應用于各種繞線(xiàn)式負載，還可以節能降耗大中型繞線(xiàn)式異步電動(dòng)機，凸顯了傳統無(wú)功補償裝置不可比擬...

電的度數和功率的關(guān)系(一功率等于多少度電)

1.電功率電功率是單位時(shí)間內電流所做的功，也就是說(shuō)1S內電流所做的功。在交流電路中，電能分為視在功率、有功功率和無(wú)功功率。1.1有功功率在之...

單相電機用什么型號電容(單相電機電容怎么選配)

1.為什么單相電機需要電容？1.兩個(gè)線(xiàn)圈同時(shí)通電。對于單相異步電動(dòng)機，只有一個(gè)交流電。定子圖A和B同時(shí)連接(線(xiàn)圈通電產(chǎn)生磁場(chǎng)，吸引轉子旋轉)...

電機的啟動(dòng)電容是多少？電工看過(guò)，但沒(méi)道理

作為一名電工，大家一定知道三相交流電機和單相交流電機的區別。只要稍微注意一下，就能發(fā)現單相交流電機比三相交流電機多了一個(gè)裝置，那就是起動(dòng)電容...

單相電機怎么接倒順開(kāi)關(guān)怎么接(怎樣連接單相電動(dòng)機倒順開(kāi)關(guān)線(xiàn))

機械給我們帶來(lái)便利的同時(shí)，保養和維修也是必須的。我們在生活中看到多的是單相電機，它的應用范圍很廣，所以有必要學(xué)習一些知識。比如單相電機的原理...

單相電機為何要加電容(單相電機為什么需要電容)

單相電機單相電機有兩個(gè)線(xiàn)圈，主線(xiàn)圈和輔助線(xiàn)圈。當單相正弦電流通過(guò)主線(xiàn)圈時(shí)，主線(xiàn)圈會(huì )產(chǎn)生交變脈動(dòng)磁場(chǎng)。這個(gè)磁場(chǎng)的強度隨時(shí)隨正弦電流的變化而變化...

單相電機有沒(méi)有不接電容的(小電機與電容接線(xiàn))

“我已經(jīng)清楚地連接了電纜，但是馬達就是不動(dòng)……”客戶(hù)打電話(huà)說(shuō)新買(mǎi)的黎明電機有問(wèn)題。我們技術(shù)員了解了情況，說(shuō)：“哦！怪不得它不會(huì )動(dòng)，因為你沒(méi)接...

三相電機始終一相帶電(三相電機變成單相電機)

在現代工業(yè)生產(chǎn)中，電機得到了廣泛的應用。但在生產(chǎn)中，因缺相運行而燒毀電機的事故占了很大比例。如何減少這些問(wèn)題，全面提高電機的效率，是一個(gè)值得...

單相洗車(chē)機電機接線(xiàn)圖(清洗機電氣原理電路控制圖)
