摘要
在当今工程的设计与实践中,变压器的装机容量选择问题一直是业内热议的焦点,如何判断建筑电气设计时变压器容量是否过大,成为评价建筑电气节能设计的重要问题。本文采集了北京、上海、广州、南京四地的大量工程实际运行数据,并以此为样本,对数据进行分析处理,通过运用正态分布和频数分布法,最后得出不同类型建筑的变压器容量指标的建议值。希望为减少能源浪费、避免固定资产投资增加以及电气的节能设计提供数据支持。
In the process of design and practice of current construction,how to choose installed capacity of transformers is always a hot topic in the industry.How to tell whether the capacity of transformer in electrical design is oversized becomes a key factor in evaluating the energy-saving design of buildings. In this article,vast engineering and practical operation sample data collected from Beijing,Shanghai,Guangzhou,and Nanjing was analyzed. Recommended values for transformer capacity in different building types are drawn out upon normal distribution and frequency distribution. The author hopes that this article can provide data support for reducing energy waste,avoiding increased investment in fixed assets,and designing energy-saving electrical system.
