低压开关的机构动态仿真分析与优化

摘要/Abstract

摘要： 低压开关的动态过程分析对于其优化设计非常重要，机构系统中碰撞接触导致的弹跳会引起电弧烧蚀，直接影响开关的电气寿命。采用虚拟样机技术对开关的闭合过程进行动态仿真，获得机构的动态过程及各接触位置的接触状态变化，并通过与开关闭合过程的弹跳时间测试结果进行对比，以及与电气寿命试验后样品的烧蚀位置进行对比，证明了仿真模型的正确性。最后通过仿真模型的正交试验研究了相关设计参数对开关弹跳的影响，分析得到机构的优化方案并进行了试验，试验结果验证了所提出方案的有效性。

Abstract: In the optimum design of low-voltage switches, it was necessary to analyze the dynamic behaviors. The bounces caused by impact contacts in the mechanical system would lead to arc ablations, and directly a effect the electrical lifetimes of the switches. With virtual prototyping technologies to do the dynamic simulations for the closing processes of the switches, the dynamic behaviors of the mechanical system and the changes of the contact status were investigated. The simulation model was verified by comparing with the bounce time tests of the switch closing processes, and the bounce positions were the same as the arc ablation positions of the test samples. The influences of the design parameters on the contact bounce of the switches were investigated through the orthogonal test of the simulation model, and the optimization method was designed and verified by the test samples.

Key words: low-voltage switch, dynamic simulation, contact bounce;orthogonal test
