韓國AUTOMA,ACV131R-15A 好貨鋪 磁場中閉合線圈的磁通量⒈定義一：φ=BS，S是與磁場方向垂直的面積，如果平面與磁場方向不垂直，應(yīng)把面積投影到與磁場垂直的方向上，求出投影面積；⒉定義二：表示穿過某一面積磁感線條數(shù)；此時，我們認(rèn)為B代表的意義是單位面積內(nèi)的磁感線密度。 接線時，1P斷路器不需要區(qū)分零火線方向——因為它只需要接火線（進(jìn)出線各一個接線柱）除了1P斷路器以外，剩下的四種斷路器都是上下各兩個接線柱，需要在接線時注意零火線的順序——上下為一組，零火線分左右（進(jìn)線的左右與出線的左右一致）。
迭式繞組由于嵌裝布線方式的變化不同，又有單雙圈交叉布線排列與單雙層混合布線排列之分；此外，從繞組端部的嵌裝形狀稱為鏈形繞組、籃形繞組，實際上均屬迭式繞組。一般三相異步電動機(jī)的定子繞組較多采用迭式繞組。三、轉(zhuǎn)子繞組轉(zhuǎn)子繞組基本上分鼠籠型和繞線型兩類。
【問題分析】電流互感器額定容量就是電流互感器額定二次電流I2e，通過二次回路額定負(fù)載Z2e時所消耗的視在功率S2e，即，S2e=I2eZ2e；因數(shù)顯表消耗的視在功率只有0.05VA，很小，所以我們可以不考慮，Z2e=ρ.2L/S=0.0176Ω.mm/m×2×200m/2.5。
