一种新型永磁驱动操作机构及其控制方案

摘要/Abstract

摘要：

回顾了采用电磁驱动、永磁保持原理的永磁电动操作机构的发展历程及最新研究进展。鉴于典型永磁电动操作机构在分合闸过程中容易加速，不易减速，分合闸特性不够理想，而改进型的永磁电动操作机构结构较为复杂，可靠性不高的特性，从操作机构的原理出发，提出了一种永磁驱动、永磁保持的新型永磁驱动操作机构，并阐述了其工作原理，分析了其静态特性，给出了其控制方案。与永磁电动操作机构相比，新型永磁驱动操作机构结构更简单、控制方案更灵活。

Abstract:

This paper introduced the developing history of permanent magnetic operating mechanism(PMOM), which was electromagnetic drived and permanent magnetic kept, and analyzed the recent research work by researchers on how to improve the performance of PMOM. As the performance of a typical PMOM was not ideal and the structure of the improved PMOM was complex, a new permanent magnetic drived and permanent magnetic kept operating mechanism was proposed. Its working principles were introduced, its static characteristics was analyzed, and its control scheme was given. Compared with the typical PMOM, this new operating mechanism has more simple structure and more flexible control scheme.
