Abstract: A power supply system includes a switch unit and an operating mechanism. The switch unit includes: an arc-extinguishing functional component, a fixed contact assembly, a moving contact, and a first magnet assembly. The arc-extinguishing functional component is located inside the arc-extinguishing functional component and can move relative to the fixed contact assembly. The operating mechanism controls the switch unit to be opened when receiving a switch-off signal, so that the moving contact is separated from the fixed contact assembly. An electric arc is formed between the moving contact and the fixed contact assembly in a separation process. Directions of at least some magnetic induction lines of the first magnet assembly intersect a current direction of the electric arc to drive the electric arc to move towards the arc-extinguishing functional component. The first magnet assembly includes a first magnet and a second magnet that are spaced apart.

Abstract: A power supply system includes a control unit, a switch, a direct current source, and a power change unit. The switch includes a switch unit and an operation mechanism. The operation mechanism is configured to receive a switch-off signal and control the switch unit to be turned on or off. The switch unit includes a first static contact, a movable contact, and a first arc extinguishing structure. When the switch unit is turned off, the movable contact rotates about a rotation center relative to the first static contact by a first included angle to be separated from the first static contact, to generate a first arc. The first arc extinguishing structure includes a first arc extinguishing end part and a second arc extinguishing end part. A connection line between the first arc extinguishing end part and the rotation center of the movable contact is a first line.

Abstract: A power mechanism, a switch, a power conversion apparatus, and a power supply system. The switch includes a contact component, a knob, and a power mechanism connected between the contact component and the knob. The power mechanism includes a fastening bracket, a knob connector, a contact connector, a transmission component, a trip unit, and a cradle. Both the knob connector and the contact connector are rotatively connected to the fastening bracket, and rotation centers of the knob connector and the contact connector are collinear. The transmission component is configured to implement power transmission between the knob connector and the contact connector. The trip unit is configured to receive a switch-off signal, to implement tripping of the trip unit and the cradle. The transmission component is driven to move by using the cradle, to separate the movable contact from the static contact, so that the switch is switched off.
