摘　　要：结合某项目地铁主所35 kV真空断路器在开断电抗器时发生的真空泡炸裂事故,对故障原因进行分析、总结,并采取相关的预防措施。建议在电抗器侧配置避雷器和阻容吸收装置并分组设置电抗器,以降低过电压水平。Combined with the vacuum envelope explosion accident of 35 kV vacuum circuit‑breaker in a metro main substation when breaking the reactor,this paper analyzes and summarizes the fault causes,and takes relevant preventive actions.To reduce the over‑voltage level,it is suggested to install a lightning arrester and resistance‑capacitance absorption device on the reactor side and set reactors in groups.
