机械式有载分接开关灭弧方案的研究

Arc Extinguishing Scheme Research on Mechanical On-Load Tap-Changer

有载分接开关是变压器在调压过程中的重要器件。介绍了传统的机械式有载分接开关及混合式有载分接开关的灭弧方案,总结了有载分接开关的改进过程,给出了三种改进方案,并进行了对比。指出全电力电子式有载分接开关将是未来的发展方向。

The on-load tap-changer is the important part for transformer in pressure regulating process. Introduction was made to the arc ex-tinguishing scheme of traditional mechanical and mixed on-load tap-changer, the improved process of the on-load tap-changer was summarized and three kinds of improved schemes were given and compared. It is pointed out that the full electric power electronic type on-load tap-changer will be the trend of development.
