Abstract

Buffer is one of the most essential parts in spring operating mechanism

its cushion performance fit and unfit quality immediate influence to the workability index of high voltage circuit breaker and the reliability of spring operating mechanism. Based on the working principle analysis and mathematical model of buffer

the circuit breaker and spring operating mechanism as a whole are simulated by Adams and MATLAB. The displacement-time characteristics of moving contact are obtained

and the results are consistent with the experimental results. The diameter and the spacing interval of buffer orifice are optimized though particle swarm optimizer arithmetic. The optimized buffer is not only satisfied with performance requirement

but also smoother deceleration process of moving contact

lower buffer force peak value

higher cushion efficiency and better reliability and service life of spring operating mechanism. This modeling and optimizing methods offer useful references for the cushion perfor-mance design and optimum of buffer.
