针对多断口真空断路器分压均匀性优化设计研究

Research on Optimal design of Voltage Distribution Uniformity of Multi Break Vacuum Circuit Breaker

断路器是保证电力系统安全运行的重要组成部分,该设备凭借自身良好安全性、使用寿命时间长等优势在中压领域得以广泛应用。为了进一步推动真空断撸起向高级电压方向发展,文章采用将间隙长度分割多个短间隙并串联的方式来实现,并设置相关实验对改变真空灭弧室电压的分布情况和提升多断口真空断路器的开断性能进行验证。

Circuit breaker is an important part to ensure the safe operation of power system.With its advantages of good safety and long service life,the circuit breaker is widely used in the medium voltage field.In order to further promote the development of vacuum interrupter to advanced voltage,the gap length is divided into several short gaps and connected in series,and relevant experiments are set up to verify the change of voltage distribution of vacuum interrupter and the improvement of breaking performance of multi break vacuum circuit breaker.
