Comprehensive Evaluation of Energy-Saving Amorphous Alloy Transformer in Distribution Grid

Firstly, this paper introduces the development of amorphous alloy transformer. According to the technical characteristics of amorphous alloy transformer and the application of Jiangsu power, the comprehensive evaluation about amorphous alloy transformer from the safety performance, the economic performance and the environmental impact are studied comparing with S11 type, S13 type and S15 type transformer. In the safety performance, overload capacity and over-excitation ability of amorphous alloy transformer is insufficient; in the economic performance, low no-load loss, high efficiency, energy saving effect of amorphous alloy transformer is obvious; in terms of environmental impact, the audible noise level of amorphous alloy transformer is higher than that of conventional transformer, and manufacturers need to study to reduce the noise level. Finally, the application recommends of amorphous alloy transformer is presented based on comprehensive evaluation.
