GN0WK2W9Q5XDZ變壓器組成部件包括器身(鐵芯、繞組、絕緣、引線)、變壓器油、油箱和冷卻裝置、調壓裝置、保護裝置(吸濕器、安全氣道、氣體繼電器、儲油柜及測溫裝置等)和出線套管。1．鐵芯鐵芯是變壓器中主要的磁路部分。通常由含硅量較高，厚度分別為0.35 mm\0.3mm\0.27 mm，表面涂有絕緣漆的熱軋或冷軋硅鋼片疊裝而成鐵芯分為鐵芯柱和橫片兩部分，鐵芯柱套有繞組；橫片是閉合磁路之用。鐵芯結構的基本形式有心式和殼式兩種2．繞組繞組是變壓器的電路部分，它是用雙絲包絕緣扁線或漆包圓線繞成。變壓器的基本原理是電磁感應原理，現以單相雙繞組變壓器為例說明其基本工作原理：當一次側繞組上加上電壓U1時，流過電流I1，在鐵芯中就產生交變磁通O1，這些磁通稱為主磁通，在它作用下，兩側繞組分別感應電勢E1，E2，感應電勢公式為：E=4.44fN?m式中：E--感應電勢有效值f--頻率N--匝數?m--主磁通最大值由于二次繞組與一次繞組匝數不同，感應電勢E1和E2大小也不同，當略去內阻抗壓降后，電壓U1和U2大小也就不同。當變壓器二次側空載時，一次側僅流過主磁通的電流（I0），這個電流稱為激磁電流。當二次側加負載流過負載電流I2時，也在鐵芯中產生磁通，力圖改變主磁通，但一次電壓不變時，主磁通是不變的，一次側就要流過兩部分電流，一部分為激磁電流I0，一部分為用來平衡I2，所以這部分電流隨著I2變化而變化。當電流乘以匝數時，就是磁勢。生產經營陽谷S11油浸式變壓器
