摘要
针对有载调容配电变压器可以根据负荷变化调整自身容量,实现配电网节能经济运行的特点,介绍有载调容配电变压器的基本结构和原理,详细分析了调容前后接线方式、电气量、绕组参数、自身损耗的变化情况,并从运行成本角度对有载调容配电变压器与普通配电变压器的差异进行了对比分析,验证了有载调容配电变压器的运行经济性。
The on-load capacity regulating transformer can adjust its capacity according to the change of load,so as to realize the energy saving and economic operation of the distribution network.This paper introduces basic structure and principle of the on-load capacity regulating transformer,anelyzes the adjustable capacity,winding connection mode,the electric parameters before and after the change of parameters, its loss,and from the controlled load capacity angle of operation cost compares and analyzes the distribution transformer with normal distribution transformer,through the contrast analysis of the differences is to verify the tuning capacity of distribution transformer running economy.
