摘要

本文主要是以現場量測與分析的方法，探討非晶質鐵心變壓器的飽和特性與磁滯迴線的求取，並對同規格之矽鋼片鐵心變壓器作相同的量測，將所得數據作分析比較。
實驗中利用諧波電壓產生器和電力品質記錄器，分別對兩台不同鐵心之單相三線桿上變壓器（25KVA）加以量測，測試電壓有效值由160V~265V，記錄其電壓、電流值進而探討其鐵損、銅損與磁滯迴線在電壓變動下的變化，與兩種變壓器的差異。實驗結果非晶質鐵心變壓器的鐵損與磁滯曲線的大小約為相同規格矽鋼片鐵心變壓器的三分之ㄧ，銅損則差異不大。
希望本研究結果可對變壓器設計者及使用者提供有利的參考，進而對變壓器製造品質及電力系統安全的提升有所助益。

This thesis analyzes the saturation characters of amorphous core transformer and re-establish it’s hysteresis loops by field measurement. The hysteresis loops of silicon steel core transformer are also measured. Then the results are compared.
We measure the different core transformers（single-phase, 6900/240 V, 25KVA） each by means of harmonic voltage generator and power quality recorder. In this experiment, the test voltages（RMS value） are chosen from 160V to 265V. We find the iron loss and hysteresis loss of amorphous core transformer are about one-third of silicon steel core transformer. However the copper loss is not much difference.
We hope that the results can serve as useful reference for the designer and user of transformer.
