摘要
以永磁式断路器为分析对象,基于毕奥-萨伐尔定律和安培力公式,理论计算断路器峰值短时耐受电流下的电动斥力,分析断路器合闸状态下动触头和传动部件的受力情况,并辅以有限元Ansys软件,简单仿真计算永磁机构的合闸保持力,以此分析断路器短耐下的电动稳定性。通过计算永磁式断路器电动斥力,能为断路器的设计提供保证。
This paper calculated the electric repulsion at short time withstand current of the circuit breaker theoretically based on the Biot Savart law and the Ampere force formula which focuses on the permanent magnetic circuit breaker. The paper also analyzed the force status of the moving contacts and the driving parts and simulated the permanent magnetic actuator＇s holding force in order to analyze the electric stability of the circuit breaker. This paper provided a theoretical method for calculating the electric repulsion, and a guarantee for the design of the circuit breaker.
