  • Publication number: 20240075653
    Abstract: A saw assembly including a base, a frame assembly disposed on the base and a rail system disposed on the frame assembly. The rail system extends in a longitudinal direction and a table assembly is slidingly disposed in the longitudinal direction on the rail system. The assembly includes a split table having a first table portion and a second table portion separated by a gap extending parallel to the longitudinal direction of the rail system. A pair of fences are mounted to the first and second table portions and bridge the gap to connect the first and second table portions to each other. The gap and corresponding channels and drain apertures allow the tile saw to channel and retain water while cutting a tile. At least one of the fences has a projection in the form of a bridge that is pivotable about the fence to move the projection away from the path of the blade.

  • Patent number: 11600460
    Abstract: A system for limiting a peak current of short-circuit current comprises a first high-frequency branch configured to provide a first high-frequency current to a first switch (1SKa) of a first phase branch of a three-phase AC when the first phase branch occurs a short-circuit; a second high-frequency branch configured to provide a second high-frequency current to a second switch (1SKc) of a second phase branch of the three-phase AC when the second phase branch occurs a short-circuit; and a third phase branch of the three-phase AC connected in parallel with the first phase branch and the second phase branch and configured to always supply power.
