摘要

非晶質鐵心變壓器是以非晶合金材料製成鐵心之變壓器，它具有超低鐵損的特性，再加上適度的降低銅損，故非晶質鐵心變壓器可說是一種具環保及省能源產品，值得推廣應用於電力系統中。油浸式非晶質鐵心變壓器的設計，可以分為電氣設計和構造設計（機械設計）兩大部份。依顧客所要求的規格，計算所需鐵心大小、線圈導體的匝數及尺寸，以及電氣特性（通常包括效率、電壓調整率、激磁電流、漏阻抗及耐壓等特性）的設計，稱為電氣設計。依照電氣設計所求出的各種參數，隨後進行構造設計，主要為絕緣間距及構造強度相關之設計並繪製製造圖面。本報告主要針對油浸式非晶質鐵心配電變壓器之電氣設計，文中首先介紹非晶質鐵心變壓器的特點及目前台電公司使用此種變壓器之現況與預期發展，然後針對此種變壓器在電氣設計上所考慮的因素及項目加以介紹，並針對鐵心、線圈及主要配件的設計方法及相關計算加以說明，最後並舉實例，以說明整個設計的過程細節以供參考。

The transformers with amorphous metal core have characteristics of very low core loss and moderate decreasing the copper loss. Therefore, they are compatible with environmental protection and energy conservation. They are widely used in the power systems. The design of amorphous metal core transformers can be divided into two major parts, namely electrical design and structure design. The electrical design, according to the specifications requested by the customers, is to calculate the core size, the conductor size and turn number of windings, and the required electrical characteristics which in general include efficiency, voltage regulation, excitation current, leakage impedance and voltage stress. Based on the electrical design parameters, the structure design is proceeded which mainly include the designs related to insulation span and strength of structure. This report mainly focuses on the electrical design of oil-immersed amorphous metal core transformers. The features of this type of transformer are first introduced, and their application situations on Taipower system and future tendency are described too. Then the considerations associated with electrical design are illustrated. Furthermore, the design method and related calculations are described in detail. Finally, a practical design case is presented for depicting the whole design procedure details.
