摘要
本文对三种无弧有载调压变压器的技术方案进行了深入的研究。分析了晶闸管与机械开关相结合的无弧有载分接开关的灭弧机理和灭弧特性 ,论述了晶闸管控制串联调压变压器的工作原理和调压性能。通过物理模拟试验明确了它们不同的灭弧效果和动态响应特性。经过对三种方案的比较 ,提出晶闸管控制串联调压变压器是无弧有载调压的最佳方案。
Three schemes of arcless on load transformer for voltage regulation are studied in this paper. To the scheme of mechanical on load tap changer combined with thyristors, its characteristic of arc suppression is analyzed in details, and a corrected scheme is then present. To the scheme of series transformer for voltage regulation controlled by thyristors, its performance of voltage regulation is illuminated. By physical tests, the effects of arc suppression and dynamic response characteristics of those schemes are figured out and compared with each other. Series transformer for voltage regulation controlled by thyristors is proved to be the best scheme in arcless on load transformer for voltage regulation in this paper.
