Definitions

  • the invention relates to a surge arrester with a gas-tight housing in which frustoconical electrodes form a gap opposite each other, which are inserted into the ends of a tubular insulating body, on the inside of which there is at least one line of electrically conductive material as an ignition line over part of the tube length in the direction extends from one electrode to the other.
  • Such a surge arrester is known from DE-AS 23 46 174.
  • the response voltage should not be affected by the distance from the ignition line to the counter electrode.
  • the ignition line connected to one electrode extends beyond the height of the gap and the distance between the ignition line and the counter electrode is greater than the gap between the two electrodes.
  • arresters that do not contain radioactive substances have the following property: If the arresters are brought from the bright room into the dark, their ignition voltage is about 2% above that at room brightness. If the arresters are in the dark for several hours or days, their ignition voltage rises to twice the value, with the collective scattering between 2% and 100% drift.
  • radioactive preparations are suitable for the pre-ionization of the gas filling, the half-life of which is of the order of the component life.
  • tritium is also used as the gas and promethium 147 or radium 226 as the solid substance.
  • the serious disadvantage of using radioactive preparations is that because of their powdery or gaseous nature there is always the possibility of contamination of the environment. Radioactive substances therefore require extensive safety precautions from the manufacturer of arresters as well as from their customers. The disposal of defective arresters is also problematic.
  • the invention has for its object to provide a gas discharge surge arrester in which no radioactive substances are used and which has only the 2% drift of the ignition voltage in the dark, which is caused by the dependence of the triggering coefficient on the light.
  • a surge arrester of the type mentioned at the outset that the ignition line 3 is connected to an electrode 1, 2 and at a distance a from the side wall and a distance b ends in front of the second electrode (1, 2), at least one of the two distances a or b being smaller than the gap length c.
  • the ignition line 3 is not connected to both electrodes, but at least one of the two sums of the ignition line distances a 1 + a 2 or b 1 + b 2 is smaller than the gap length c.
  • the ignition line 3 is electrically conductively connected at both ends to the respective electrode (1, 2) and preferably has an interruption outside the gap space, the length 1 of which is less than the gap length c.
  • the electrodes are provided with an activating compound on their active surfaces, the triggering coefficient of which is greater than the triggering coefficient of the material of the primer, for which pencil graphite is particularly suitable.
  • the ignition line preferably ends at a distance a in front of the respective electrode, which is less than half the gap length c.
  • the distance a or a 1 + a 2 of the ends of the ignition stroke to the respective side wall of the electrodes is smaller than the distance b or b 1 + b 2 to the bottom of the electrodes.
  • tubular insulating body is made of glass, it is advantageous to roughen the insulating body at least on its inside by etching to apply the primer.
  • the distances between the ignition lines are first made too small and, after the arrester has been sealed gas-tight, they are burned to the desired size by applying a voltage and igniting the arrester. It is expedient to add 0.1% to 10% oxygen to the gas atmosphere of the arrester when the electrodes melt, so that the combustion of the graphite used as the material for the primer is accelerated.
  • Surge arrester shown schematically in section consists of a gas-tight housing in which frusto-conical electrodes 1, 2 face each other forming a gap c, which are inserted into the ends of a tubular insulating body 4.
  • the ignition line 3 ends at a distance b in front of the respective electrode 1 or 2, at least one of the two distances a or b being smaller than the gap length c.
  • the distance a between the ends of the priming line 3 and the respective side wall of the electrodes 1, 2 is preferably smaller than the distance b between the bottom of the electrodes 1, 2, because this requires good insulation between the electrodes.
  • the ignition line 3 is not connected to any of the two electrodes 1, 2 in an electrically conductive manner. Therefore, at least one of the two primer spacing sums a 1 + a 2 or b 1 + b 2 is smaller than the electrode spacing c.
  • the ignition dash 3 is the ignition dash 3 connected to both electrodes 1, 2.
  • the ignition 3 is interrupted outside the combustion chamber over the length 1, 1 being smaller than the electrode spacing.
