Xiang Chi · Power System Technology · 2008
In this paper, the present operation situation of distribution transformers in rural power network and the factors hindering the popularization and application of amorphous alloy distribution transformers are analyzed. The performance and features of amorphous material, the level of production technology and application situation of amorphous alloy distribution transformers home and abroad are presented. In the aspects of annual operating cost, investment payback period, relation between efficiency and load factor as well as total owning cost (TOC), the theoretical calculation and analysis of energy-saving effect of amorphous alloy distribution transformer are conducted; to directly reflect the optimal load rate and comprehensive economy of amorphous alloy distribution transformer, the graphic charts are used to provide basis for reasonable selection of amorphous alloy distribution transformers. Several problems to be paid attention to during the ordering and adoption of amorphous alloy distribution transformers are put forward and the suggestions related to the selection of capacity and installation locale of amorphous alloy distribution transformers are given.
