Summary:The invention belongs to the technical field of vacuum switches, and particularly relates to a vacuum circuit breaker. The vacuum circuit breaker comprises a shell, solid-sealed polar poles are sequentially arranged on the shell, insulating pull rods are arranged in the solid-sealed polar poles, each insulating pull rod is connected with a corresponding electromagnetic driver, and the electromagnetic drivers are arranged in the shell. According to the invention, by arranging the corresponding electromagnetic driver for each phase of solid-sealed polar pole, simultaneous driving of three phases of the circuit breaker during action can be effectively ensured, so that the synchronism of action is improved. 本发明属于真空开关技术领域，尤其涉及一种真空断路器。真空断路器包括壳体，壳体上设置有依次布置的固封极柱，所述固封极柱中设置有绝缘拉杆，各绝缘拉杆均连接有对应的电磁驱动器，所述电磁驱动器设置于壳体中。本发明通过为每相固封极柱设置对应的电磁驱动器，可以有效保证断路器的三相在动作时同时驱动，从而提高动作的同步性。
