摘要:

触头的分断速度是影响接触器燃弧特性的重要因素,动触头的运动速度依赖于弹簧刚度、阻尼及压缩量,因此探究压簧参数对动触头运动状态的影响十分必要。建立双断点接触器触头分断过程的动触头及可动部分的运动状态方程,理论与仿真验证结果表明,理论模型与仿真的计算结果具有较好的一致性。进一步探究影响因素对动触头及可动部分运动速度的影响,结果显示,可动部分运动末速度与影响因素的关系可近似用简单函数表征。

关键词: 分断速度, 运动状态函数, 压簧参数, 行程参数

Abstract:

Breaking speed of contact is an important factor affecting the arcing characteristics of contactors.Motion speed of the moving contact depends on spring stiffness,damping,and compression.Hence,it is necessary to explore the influence of spring parameters on the motion state of the moving contact.A constitutive model of moving contact and movable parts during the contact breaking process for double-break contactors is devoted to being established. Theoretical and simulation results indicate good consistency.Subsequently,the influencing factors on the motion speed of the moving contact and movable parts are investigated.The results demonstrate that the relationship between the final velocity of movable parts and the influencing factors can be approximated by simple functions.

Key words: breaking speed, motion-state function, spring parameters, travel parameters
