摘要: Embodiments of this application provide a switch, a power conversion apparatus, and a power supply system. The power supply system includes a control unit, a switch, a direct current source, and a power conversion unit. The switch is electrically connected between the direct current source and the power conversion unit, and the control unit is configured to send a switch-off signal to the switch when a fault occurs on the direct current source or the power conversion unit. The switch includes a contact component, a trip-free structure, and a knob that are sequentially disposed in a stacked manner in a first direction. A trip unit of the trip-free structure is configured to receive the switch-off signal, to unlock the trip unit from the cradle. The cradle drives the connecting rod structure to move, to separate the moving contact from the fixed contact. When a circuit is faulty, the power supply system can automatically drive the switch provided in this application to be switched off without a manual operation.

摘要: The invention relates to a changeover switch for medium voltage switchgear, which changeover switch comprises:
- a first terminal body
- a second terminal body
- two elongate pole bodies arranged parallel to each other and rotatable arranged with first ends on opposite sides of, and in direct contact with the first terminal body around a rotation axis,
wherein the two elongate pole bodies are rotatable between an open position and a closed position, wherein the second ends of the two elongate pole bodies are positioned in direct contact with opposite sides of the second terminal body; and
- spring means arranged between the two elongate pole bodies to urge the pole bodies towards each other.-

摘要: An electric switch comprising a frame (2), a first stationary contact (41), a roll element (6) adapted to rotate relative to the frame (2), a rotating contact (8) stationary fixed to the roll element (6), and an arc extinguisher plate system. The arc extinguisher plate system comprises at least one first arc extinguisher plate (11) for extinguishing an electric arc generated during an opening event between the first stationary contact (41) and a first contact portion (81) of the rotating contact (8). The at least one first arc extinguisher plate (11) is fixed to the roll element (6).

摘要: A switching apparatus for electric power distribution grids comprising:
- one or more electric poles;
- for each electric pole, at least a fixed contact and a movable contact, said movable contact being reversibly movable between a coupled position, at which said movable contact is coupled to said fixed contact, and an uncoupled position, at which said movable contact is separated from said fixed contact;
- for each electric pole, an arc-breaking assembly comprising a plurality of arc-breaking plates arranged side by side and spaced one from another;
Said arc-breaking assembly comprises shielding means of electrically insulating material operatively coupled to said fixed contact and to said arc-breaking plates.
Said shielding means partially cover surfaces of said fixed contact and said arc-breaking plates, which are exposed to possible electric arcs, during an opening manoeuvre of said switching apparatus.-
