摘　　要：操作机构是配电开关柜的核心部件,直接决定了配电开关柜的性能,当前的弹簧操作机构、永磁操作机构和电磁操作机构在应用过程中都各有优劣。介绍了一种基于新型FeGa磁致伸缩合金的快速操作机构,从技术参数设定原则和关键部件的设计过程上着手,设计了一款结构简单、体积小、操作电流小、动作时间短且寿命长的操作机构。经过对样品的测试验证,该快速操作机构在电气性能与机械特性指标上均满足设计预期。The operating mechanism is the core component of the distribution switch cabinet,which directly determines the performance of the distribution switch cabinet.The current spring operating mechanism,permanent magnet operating mechanism,and electromagnetic operating mechanism all have their own advantages and disadvantages in the application process.This article introduces a fast operating mechanism based on a new FeGa magnetostrictive alloy.Starting from the principles of technical parameter setting and the design process of key components,a simple structure,small volume,low operating current,short action time,and long service life operating mechanism is designed.After testing and verifying the samples,the quick operating mechanism meets the design expectations in terms of electrical and mechanical performance indicators.
