Definitions

  • Object of the present invention is to develop a circuit breaker of the type mentioned, which has a higher current carrying capacity.
  • connection means are electron beam welded. Electron beam welding is particularly advantageous because the welds are executable in high precision.
  • FIG. 2 shows the solid contact 12 of the vacuum interrupter 5 in the form of a cylindrical bolt is connected to the first connection means 13 in the form of a copper-shaped plate having a bolt of the fixed contact 12 corresponding recess in the area 17 encircling electron beam welded, creating a non-positive and cohesive connection between the fixed contact 12 and the second connection means 13 is formed.
  • the second connection means 13 is also further electron beam welded to the first busbars 6 in the region 18.
  • To stabilize an aluminum spacer 19 is disposed between the busbars.
  • FIG. 3 shows a detailed view in the region of the moving contact of the vacuum interrupter 5 from the FIG. 1 ,
  • the moving contact 8 is electron beam welded at its tapered end 20 in the area 21 circumferentially with the second connection means 11 in the form of a copper-shaped plate with a corresponding recess of the bolt 20 of the moving contact 8 recess.
  • Flexible conductors 22 and 23 are also electron beam welded in the regions 24 to the second connection means 11 and electron beam welded at 26 and 27 to the second bus bar 7. Due to the non-positive and cohesive connection in the regions 21, 24, 25, 26 and 27, no further screw connections are required as fastening means in the region of the flexible current conductors 22 and 23 and the moving contact 8.
