Summary:The utility model relates to a vacuum breaker, which belongs to switches of high voltage appliances. The utility model is characterized in that a movable contact positioned at the lower end of a vacuum envelope and a flexible connector are integral transition connecting pieces, and the number of the transition connecting position of each phase at the inner part of the breaker is only three. The utility model is used for the control of 10KV circuits, and because the number of lapped surfaces at the inner part of the breaker is small, contact resistance is reduced. The temperature when the breaker works is decreased, and the operational reliability is improved.
