有载调容变压器技术参数的选择探讨

摘要

Expanding the application of on-load capacity regulating transformer is beneficial to the popularization of it. Two kinds of on-load capacity regulating transformers, which were different from the combination of high and low capacity, were carried out comparison and analysis on the reliability and economical efficiency. The short-circuit impedance value under low capacity should not be taken as the constraint condi-tion of combined capacity size, but make a choice according to load fluctuation of transformer practical installation site and economic operation requirement. The S13-type energy-saving products were adopted to raise the low capacity rating appropriately, which is conducive to decrease primary input-cost and can obtain good economic and social benefits.%扩大有载调容变压器的适用范围有利于该产品的推广应用。从可靠性、经济性两方面对两种有载调容变压器大小容量组合方案进行了对比分析，认为小容量下的短路阻抗值不应作为大小容量组合的约束条件，应根据变压器实际安装场合的负荷波动大小按经济运行要求来选择，采用 S13型节能型产品，适当提高小容量额定值，有利于减少一次性投入，获得较好的经济效益和社会效益。
