摘要

随着对可靠性要求的不断提高,人们越来越关注开发有效的断开系统,以提高工程系统的安全性并防止故障升级。考虑到这一前景,本文介绍并讨论了由一个同轴磁耦合器和一个电磁装置组成的两个断开执行器的优化设计。断开执行器通过同轴磁耦合器提供非接触式扭矩传输,而电磁装置则在通过专用算法检测到故障的情况下中断扭矩传输。所执行的设计程序依赖于二维有限元分析和权衡研究,以实现电磁装置的优化几何形状。最后,对两个用于高速和高扭矩应用的断开执行器进行了原型设计和测试,目的是评估其断开能力。对这两个断开致动器的显影力和电压电流特性以及断开时间进行了测量。

Design and Testing of Disconnection Actuators for Enhancing Safety and Preventing Failure Escalation
The growing demand for reliability has led to an increased interest in developing effective disconnection systems for enhancing the safety of and preventing failure escalation in engineering systems. Considering this prospect, the design optimization of two disconnection actuators composed of a coaxial magnetic coupling linked to an electromagnetic device is presented and discussed. The disconnection actuator delivers a contactless torque transmission through the coaxial magnetic coupling, whereas the torque transfer is interrupted by the electromagnetic device in case a failure is detected via a dedicated algorithm. The performed design procedure relies on 2D finite element analysis, and trade-off studies are carried out to achieve an optimized geometry of an electromagnetic device. Finally, two disconnection actuators, for high-speed and high-torque applications, are prototyped and tested, with the aim of evaluating their disconnection capability. For both disconnection actuators, the developed force and voltage–current characteristics are measured along with the disconnection time.
