    摘 要:電網中無功功率的變化會導致電壓的波動,為調節無功功率,需對電壓進行調節,電力變壓器有載分接開關是電壓調節的重要手段。通過分析不同類型有載分接開關的工作原理和調壓過程,對機械式、電力電子式和混合式有載分接開關進行了對比研究,總結了它們的優缺點。介紹了三種混合式有載分接開關的結構及實現時存在的技術難點,為進一步開展混合式有載分接開關研究提供了參考。

    Abstract: Changes of reactive power will lead to voltage fluctuations in power system. In order to adjust reactive power, there is a need to have voltage adjustment, and power transformer on-load tap-changer is an important means for voltage adjustment. Via analysis of working principle and on-load tap-changer voltage adjusting process of different kind of on-load tap-changers, comparisons were carried out for mechanical type, power electronic type and hybrid type, their advantages and disadvantages summarized. Introduction was made to structures and existing technical difficulties in realization for three kinds of hybrid type on-load tap-changers, which provided reference for further carrying out hybrid type on-load tap-changer study.
           Key words: on-load tap-changer; mechanical; power electronic type; hybrid
