摘要

文中研究目标是确定126 kV真空断路器触头合闸冲击力的大小以及相关因素的影响。利用PVDF压电传感器测量了合闸过程中触头冲击力曲线。得到合闸速度约为1.5 m/s时冲击力峰值为97 995 N

持续时间为0.487 ms。通过Ansys/LS-DYNA软件仿真研究了触头的凸台直径、材料弹性模量、合闸速度以及触头弹簧力对合闸冲击力的影响。仿真结果表明:触头凸台直径对触头冲击力基本无影响;触头材料弹性模量增大时

触头冲击力峰值增大

冲击力持续时间减小;触头合闸速度以及触头弹簧力增大时

触头冲击力峰值增大

冲击力持续时间基本不变。

Abstract

The object of this paper is to determine the closing impact force of a 126 kV vacuum circuit breaker and the influence of related factors. The impact force is measured by using PVDF piezoelectric sensors. The peak value of impact force is measured as 97 995 N and the duration is 0.487 ms when the closing speed is 1.5 m/s. The influence of the contact shape

the elastic modulus of the contact material

the contact closing speed and the spring force on the contact impact force during the closing process is studied by Ansys/LS-DYNA simulation. The simulation results show that: the contact shape has no effect on the impact force of the contact. As the elastic modulus of the contact material increases

the peak value of the contact force increases and the duration of the impact force decreases. As the contact closing speed or spring force increases

the peak value of the contact impact force increases

and the duration of the impact force basically unchanged.
