Definitions

  • the switching rod 54 is hollow and is inserted in a blow piston 58 upon which a rod of insulating material 59 is secured.
  • the piston 58 slides in the cylinder 60 which likewise is carried by the high voltage conductor 51.
  • the rod 59 is coupled with a drive crank 61 which is pivotally mounted on a shaft 62.
  • the shaft 62 extends out of the metal capsule 49.
