Darfon Power BD Introduction

定義:所謂線圈,本來是指纏繞捲成螺狀狀之電氣零件而言,與電氣的導通與否及與磁束相交與否並無關聯,但在電氣學上,係指具有幾何學上捲成一繞一繞的電流通路而在電路內部具有作為電感的作用之電子零件而言。所謂變壓器是指將具有共通之磁氣迴路之兩個線圈組合起來,而利用電磁感應來施行交流電壓之昇降或阻抗之變換的一種電子零件。

名稱:線圈有時稱為電感線圈、電感器或簡稱 L ,在與電力有關之方面,又稱電抗器。日文的 Trans 是 Transformer 省略,表示可使性質、機能等起變化或變形的東西之意,本來 Trans 是表示變化、移轉的接頭語,並不是完整的用語,但日本人卻習慣於使用 Trans 來代表 Transformer ,此外在日文中,也常使用「變成器」、「變壓器」的稱呼。

TransformerTransformer

分類上之位置:線圈與變壓器祇有兩端子與四端子之差而已,因此雖然再機能上有些差異,但在設計及構造上,卻沒有本質上的不同,因此在分類上也採用概括的分類,有時也採用將其列入電感零件或繞線 ( 繞阻 ) 零件之分類辦法。電子零件→被動零件→線圈、變壓器
