Definitions

  • the invention relates to a surge arrester made of a cylindrical insulating body as a structural unit with two electrodes for protecting telecommunications systems against overvoltages, surge currents and surge voltages.
  • Comparable surge arresters that have been known for a long time have a gas spark gap and are sealed airtight.
  • the invention has for its object to develop a surge arrester of the type mentioned, which is simpler in construction and can be produced with less effort than the known surge arrester with a gas spark gap, the design of the surge arrester being designed such that it can also be optionally used in existing recording magazines Replacement for known surge arresters can be used.
  • the insulating body of the surge arrester forming an air spark gap is arranged as a pin which has a dome at one pin end for the spark jump and at the other pin end has an abutting contact surface on the insulating body, and that a disk-shaped counter electrode is provided on the other end face of the cylindrical insulating body and a groove and an erosion collar are arranged on this end face.
  • An earth rail can be provided as a counter electrode as a counter electrode.
  • the insulating body expediently has two or three spark outlet openings which are arranged offset by 180 ° or 120 °.
  • the electrode designed as a pin advantageously has the shape of a hollow pin, the edges of which are crimped for holding in the insulating body, one crimp forming the contact surface.
  • an electrode 2 designed as a pin is arranged in the cylindrical insulating body 1 a of the surge arrester 1.
  • This electrode 2 has at one end of the pin for the spark jump a tip 2a and at the other end a contact surface 2b lying on the end face of the insulating body 1a.
  • a disk-shaped counter electrode 3 is arranged on the other end face of the insulating body 1 a.
  • a groove 1b is provided on this end face as a creepage distance and an erosion collar 1c which serves as an erosion brake (erosion limitation).
  • This burn-up collar lc limits z. B. with a surge current load and largely prevents a reduction in insulation resistance at the creepage distance.
  • a spark discharge opening 5 indicated by dashed lines can be seen.
  • FIG. 2 shows that, instead of the disk-shaped counterelectrode 3, depending on the intended use, an earth rail 4 can also be used as a discharge rail.
  • the remaining parts correspond to FIG. 1.
  • Fig. 3 shows that spark discharge openings 5 are provided in the cylindrical insulating body la, which are only indicated by dashed lines in Figs. 1, 2 and 4. There may preferably be two or three, but also more spark discharge openings, in particular at the same angular spacing distributed over the circumference of the insulator. They are used both for blowing out sparks and for reducing pressure and temperature, since in a closed spark chamber, when there is a current load, considerable pressure builds up while the temperature rises.
  • the remaining reference numerals designate the same parts as in FIG. 2.
  • the electrode 2 is designed as a hollow pin 2c.
  • edges 2d, 2e of the hollow pin 2c are flanged for holding in the insulating body la, the flanged edge 2d forming the contact surface 2b 'of the surge arrester 1.
  • the remaining reference numerals designate the same parts as in FIGS. 2 and 3.
