Title:
SWITCH UNIT, ISOLATION SWITCH, AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/017046
Kind Code:
A1
Abstract:
The present application relates to the technical field of low-voltage electric appliances, and discloses a switch unit, an isolation switch, and a power supply system. The switch unit of the present application comprises a housing having a cavity; static contacts are arranged in offset positions in a first direction on two opposing side walls of the housing; the static contacts extend into the cavity; a moving contact driven to rotate is provided in the cavity; during the rotating process, two ends of the moving contact are respectively in contact with the static contacts on the two sides to be in a closed state or separated from the static contacts on the two sides to be in an open state; in the closed state, an included angle between an extension direction of the moving contact and a second direction ranges from 15° to 65°; arc extinguishing chambers are provided on two opposite sides in the cavity in the second direction; the arc extinguishing chambers are provided on the sides of the static contacts farthest from the moving contact, and extend and are arranged in the rotating direction of the moving contact; and the first direction is perpendicular to the second direction. The switch unit, the isolation switch, and the power supply system provided by the present application can improve the arc extinguishing effect of the switch unit.
