Definitions

  • the interrupting portions 30 are formed on the insulating plates 13 of the arc extinguishing plates 15 in the present embodiment.
  • the arc extinguishing plate 15 is disposed such that the surface on which the interrupting portions 30 are formed faces downward as shown in FIG. 4 .
  • the interrupting portions 30 are preferably formed in regions in which the grids 12 are disposed on the arc extinguishing plate 15. Specifically, the interrupting portions 30 are preferably formed on the surfaces of the grids 12 stacked on the arc extinguishing plate 15 or at locations that: are present on a surface, of the arc extinguishing plate 15, that is opposite to the surface on which the grids 12 are formed; and correspond to the locations at which the grids 12 are formed.
  • FIG. 5 is a modification in which a grid 12 is disposed between the insulating plate 13 and interrupting portions 30. This arrangement also makes it possible to obtain the favorable effect of controlling the arc.
  • each interrupting portion 30 having the bent portions disposed so as to face each other have been used.
  • an example has been shown in which four interrupting portions 30 originating from edges of the opening at the center and extending to edges on the outer peripheral side are used on one arc extinguishing plate 15.
  • the shape of each interrupting portion 30 is not limited to a bent shape and a projecting shape in the form of a line.
