摘　　要：对真空断路器和二氧化碳气体断路器的串联的耦合和相互作用进行了实验描述,轴磁场型真空断路器的弧后电流是影响两个串联断路器之间相互作用的重要参数。通过比较单个真空断路器和混合断路器不同电流零点的行为,两个断路器上的电压分布是串联连接的主要评估标准。在电流过零点后,弧后电流对电压分布有主导影响,过渡阶段导致电容性分压阶段。In this paper,the coupling and interaction of a vacuum circuit breaker and a gas circuit breaker filled with carbon dioxide connected in series are described experimentally.The post-arc current of the axial magnetic field type vacuum circuit breaker is an important parameter affecting the interaction between the two series circuit breakers and is the focus of this paper.By comparing the behavior of a single vacuum breaker and a hybrid breaker with different current zeros,the voltage distribution across the two breakers is the main evaluation criterion for the series connection.After the current crossing the zero point,the post-arc current has a dominant influence on the voltage distribution and the transition phase leads to a capacitive voltage dividing phase.
