韓國AUTOMA,AQL04-25A店鋪推薦 我仔佃查看互感器的穿芯匝數(shù)。如下圖a所示圖a明顯繞線方法錯(cuò)誤，原接線電工誤以為計(jì)算繞線匝數(shù)是以繞在鐵芯外圈的數(shù)為標(biāo)準(zhǔn)，實(shí)際應(yīng)以穿繞入互感器中心的圈數(shù)為標(biāo)準(zhǔn)，導(dǎo)線每穿過“窗口”一次，為一匝來計(jì)算，因/此發(fā)生錯(cuò)誤。
在后兩種電路中，功率因數(shù)都為0。對(duì)于一般性負(fù)載的電路，功率因數(shù)就介于0與1之間。一般來說，絡(luò)中，用電器的功率因數(shù)有兩方面的意義，一是可以減小輸電線路上的功率損失；二是可以充分發(fā)揮電力設(shè)備（如發(fā)電機(jī)、變壓器等）的潛力。

韓國AUTOMA,AQL04-25A店鋪推薦 發(fā)生短路事故時(shí)，電路中的短路電流可達(dá)40kA，甚至更大。斷路器承受的電動(dòng)力可達(dá)幾千牛以上，操作機(jī)構(gòu)必須克服如此巨大的電動(dòng)力，才能關(guān)合斷路器。2保持合閘為了縮小斷路器整體尺寸和降低能耗，合閘線圈被設(shè)計(jì)成短時(shí)工作制，只允許在很短的時(shí)間內(nèi)通以合閘電流，若通電時(shí)間過長，會(huì)燒毀合閘線圈。
比如上海電器開關(guān)廠生產(chǎn)的DZ47LE-162PC16A型漏電斷路器，其中2P就是級(jí)數(shù)，除此之外，在漏電斷路器中還會(huì)碰到諸如，4P，+N等各種不同類型的級(jí)數(shù)，不同的級(jí)數(shù)又各自代表著什么意思呢，這據(jù)個(gè)人理解。 多用在控制三相交流回路電源的三根相線，接下來介紹下這個(gè)級(jí)數(shù)中的P和N各自有什么含義，上的一些資料整理，從兩個(gè)方面進(jìn)行討論:一:從產(chǎn)品分類來說1P，2P，1P+N，，4P，4P+N，P指的是裝設(shè)了保護(hù)的極(刀極)。

這種情況下，一般是不能合閘的。要想判斷斷路器是否是由于漏電合不上閘，也很簡單。在漏電斷路器上，會(huì)有一個(gè)按鈕，按鈕的旁邊用小字寫著“合閘前按下”。當(dāng)斷路器由于漏電跳閘后，這個(gè)按鈕會(huì)突出來。一方面是提醒你，電路中發(fā)生漏電了。
