非晶配变与调容变的节能分析

本文推导了调容变高档位与低档位容量之间切换的临界负载率的计算公式,给出了配变年运行有功能耗的计算公式,并采用Excel表计算和画出了配变年运行有功能耗——负载率的曲线,分析了非晶配变的节能效果。

An Energy Saving Analysis of Amorphous Metal Distribution Transformer and Capacity Regulating Distribution Transformer

This paper deduces the calculation formula of the critical load rate(generated when high-grade and low-grade capacity switches)of the on-load capacity and voltage regulating silicon steel distribution transformer,then gives the calculation formula of the annual active energy consumption,and draws the load rate curve of annual active energy consumption of distribution transformer via Excel,the energy-saving effect of amorphous metal distribution transformers is concluded.
