变压器运行效率与最佳运行效率的计算

摘要

The input power and output power are continuously changing, so does the operating efficiency of transformer due to the difference between the power supply object and load nature. For this reason, designer should firstly understand the power supply object and operation characteristic of load when selecting the transformer and then correctly select the transformer capacity comprehensively considering other conditions based on acquisition of optimal operating efficiency of transformer. The calculating method proposed in this paper for operating efficiency and optimal operating efficiency of transformer has practical value for the economic and energy-saving operation of transformer.%由于供电对象与负荷性质的差异，变压器运行中的输入、输出功率在不断地变化，变压器运行时的效率不是恒定不变的，因此，在选择变压器时，首先应了解供电对象和负荷运行特点，在求得变压器最佳运行效率的基础上，再综合考虑其它条件来正确选取变压器容量，本文介绍的变压器运行效率与最佳运行效率的计算对变压器的经济、节能运行具有实用参考价值。
