The granted patent (Publication Number: US11887799B2) discloses an arc-extinguishing apparatus for an air circuit breaker. The apparatus includes a chamber unit with receiving grooves, a dividing unit with grids and insulating caps, a filter unit for removing substances from the fluid, and a cover unit with discharge holes. The grids divide the fluid path into multiple paths, with ventilation channels defined between them.
Furthermore, the apparatus features a filter unit with first and second filters, where the second filter has a smaller pore size than the first filter. An insulating film with communication holes is placed between the dividing unit and the filter unit. The insulating caps prevent fluid from branching to the top of the grid, ensuring efficient operation. Overall, the design of the arc-extinguishing apparatus aims to enhance the performance and reliability of air circuit breakers by effectively filtering substances and controlling the flow of fluid through the device.
