摘要： Provided is a switchgear, including: a stationary contact; a movable contact, which is configured to be shifted between a closed position and an opened position; an electromagnetic actuator, which is configured to generate power for shifting the movable contact, the electromagnetic actuator including a stator and a movable element; and a power transmission unit, which is configured to shift the movable contact through transmission of the power of the electromagnetic actuator, and to press the movable contact against the stationary contact when the movable contact is located at the closed position, the power transmission unit including: a drive unit-side spring bearing portion, which is configured to be shifted together with the movable element; a contact-side spring bearing portion, which is provided so as to be opposed to the drive unit-side spring bearing portion, and is configured to be shifted together with the movable contact; and a spring member, which is provided between the drive unit-side spring bearing portion and the contact-side spring bearing portion, the spring member including: an outer spring; and an inner spring, which is connected in parallel to the outer spring, and is arranged so as to be contracted by the same amount as the outer spring during a period in which the movable contact is shifted from a state of being located at the opened position to a state of being located at a terminal end of switch-on action.

摘要： Provided are: a vacuum interrupter (1) having a fixed contact (1a) and a movable contact (1b); a fixed side mounting plate (2) which supports a fixed side conductor (1d) connected to the fixed contact (1a); a cylindrical insulation support (3) in which the vacuum interrupter (1) is contained and to which the fixed side mounting plate (2) is firmly fixed at one end side; and an operating mechanism which is coupled to a movable side conductor (1e) connected to the movable contact (1b) and performs opening and closing operation of both the contacts. The fixed side mounting plate (2) is configured such that a plurality of plate-like members are overlapped; an exposed portion of the fixed side conductor (1d) exposed to the outside of the vacuum vessel (1) is attached with a divided terminal (6) which has a fitting hole to be fitted to the exposed portion and is formed with a slit in a radial direction from the fitting hole; and the divided terminal (6) is fixed to the fixed side mounting plate (2) and the fixed side conductor (1d) is supported by the fixed side mounting plate (2) via the divided terminal (6).
