| titleOfInvention | Vacuum switch provided with horseshoe-shaped elements for generating an axial magnetic field |
| abstract | ABSTRACT Electrical vacuum switch provided with two mutually movable contacts of conductive material, mounted on the ends of a fixed or movable contact rod, with a laminated horseshoe-shaped ferromagnetic element being fitted around each contact rod. The magnetic circuit around the contact rod consists of a section of low magnetic resistance and a section of a high magnetic resistance. The circular base of the U-shaped inner cavity of the horseshoe-shaped element is adjacent to the associated contact rod and the elements are offset through 180°C with respect to each other, so that the internal magnetic fields generated in the horseshoe-shaped elements when current passes through the switch, to the extent that the section with high magnetic resistance is approached, are mainly oriented axially between the two horseshoe-shaped elements. Said elements are so designed that their magnetic resistance to the internal magnetic field increases in going from the U-shaped base section to the section with high magnetic resistance. |
