摘要 针对断路器隔离开关触头接触压力的测量需求,设计了一种能够快速测量隔离开关触头接触压力的传感器。首先建立弹性体力学模型,初定了弹性体的结构尺寸,并利用有限元法分析了弹性体的受力情况,确定了应变片最佳贴片位置;其次通过正交试验对弹性体结构进行优化,结果表明传感器综合性能提升了19.5%;最后通过对比传感器的试验参数验证了有限元模型的正确性,证明了弹性体结构设计的合理性。 To meet the measurement requirements of contact pressure in disconnector contacts,a sensor capable of rapidly measuring the contact pressure is designed.First,the elastomer's structural dimensions were preliminarily determined by establishing a mechanical model.Using finite element method(FEM),the mechanical behavior of the elastomer was studied,and the optimal strain gauge attachment location was identified.Next,orthogonal experiments were conducted to optimize the elastomer's structure,resulting in a 19.5%improvement in the sensor's overall performance.Finally,the accuracy of the finite element model is validated by comparing experimental data,confirming the rationality of the elastomers structural design.
