Definitions

  • the invention relates to a surge arrester, in particular for the limitation of overvoltages in low-voltage systems and for the lightning protection coupling of galvanically isolated circuits, with at least one spark gap, the electrodes of which are kept at a distance by means of an insulating piece.
  • Surge arresters have become known, for example, from DE-OS 23 37 743 and 26 27 648, the overturning point in the outer region either between the jacket surfaces of the preferably planar, disk-shaped electrodes, the end faces of which are kept at a distance by an insulation layer, or between the jacket surface which forms one and the end face of the other electrode.
  • This surge arrester it is from Advantage that the energy generated during the rollover can be dissipated quickly, thus eliminating the risk of explosion.
  • the disadvantage is that the extinguishing behavior for network after-flows is not quite optimal.
  • the surge arrester according to the invention has the advantage that the energy generated during the flashover is used in a chamber adjacent to the arc area and having openings to generate extinguishing gas from the chamber walls made of appropriate insulating material in such a way that the arc is pushed away from the gap and the ionized gases are blown to the outside so that no further ignition can take place after the overvoltage has ended due to the mains voltage.
  • corresponding geometrical designs of the electrodes and the chambers surrounding them have a "broadband" quenching behavior, i.e. achieved for any current.
  • the arc discharge area 1 is located between the lateral surfaces of the disk-shaped electrodes 2, 3 and 3, 4, which are kept at a distance by insulating disks 6, 6 ' will.
  • the arrangement of hollow cylinders 6a, 6b, which consist of hard gas or a similar substance that gives off gas under the action of heat, and have outlet openings around the electrodes or around the arc area, ensures that quenching gas is generated by the heat of the arc, which Arc is slightly pushed outwards and is extinguished after the overvoltage has ended, so that no renewed ignition can take place after the mains voltage returns.
  • a common hollow cylinder 6a is arranged over both spark gaps, the spark gaps being sealed off from one another so that they cannot unite.
  • the hollow cylinder 6a has annular outlet openings 8 at the top and bottom and bore hole-shaped outlet openings 8b on its outer surface.
  • the upper radio link has a distance switch 6, which can also consist of hard gas or a similar substance that emits gas in the region 1 under the action of heat from the arc. Such a distance switch provides an additional improvement in the extinguishing behavior.
  • the lower spark gap between the electrodes 3 and 4 has a spacer 6 ', which does not consist of Harugas but of mica. This has the advantage that the double spark gap still has the required insulation resistance if the hard gas intermediate piece 6 of the upper spark gap has burned or melted after a long period of use and is no longer able to sufficiently isolate the electrodes 2 and 3 from one another.
  • each spark gap is surrounded by a hollow cylinder made of hard gas 6b.
  • This hollow cylinder is in each case on the outer electrodes 2 and 4 in their likewise hollow cylindrical extensions 20 and 40 inserted such that there is only one opening on the connecting piece 30 of the two electrodes 3.
  • the two radio links are also sealed off by an annular insulating material body 6c around the connecting piece 30, so that they cannot unite.
  • This arrangement of electrodes and insulating material body creates a chamber-like area 5 on the outer electrodes 2, 4, in which a gas overpressure can form during the arc discharge. This excess gas pressure can dissipate via the annular channel 10 and past the annular insulating material body 6c through the band-ring-shaped opening 8, the arc discharge area being blown out cleanly.
  • Fig. 2a shows another embodiment of the invention, wherein a hollow cylindrical top electrode 2 is placed over a cylindrical lower electrode 3 in such a way that a closed chamber 5 is formed between the end faces and an arc discharge can develop between the outer surfaces in the area 1.
  • a hollow-liner-shaped body made of hard gas 6e between the jacket surfaces, so that the arc cannot migrate into chamber 5, and especially with larger currents down into area 1 'between the outer jacket surface of the lower inner one Electrode 3 and the phase surface 21 or the lower end face 22 of the electrode 2 is pressed.
  • the electrode 2 has a disc-shaped extension 20 at the top.
  • a hollow cylinder made of hard gas 6d which is closed on one side, is arranged as a spacer 9, so that an annular chamber 10 is formed.
  • the hard gas cylinder has borehole-shaped openings 8a, b on its bottom surface and on its lateral surface, through which openings that arise during the arc discharge Gases can escape, the excess pressure arising in the chamber 5 contributing to the fact that the arc discharge area is blown out cleanly.
  • FIG. 2b shows an advantageous embodiment of the invention, three disc-shaped electrodes 2, 3, 4, which are insulated from one another by disc-shaped spacers 6, 6 'and are kept at a distance, are arranged one above the other. Both spark gaps are surrounded by a hollow cylinder made of hard gas 6f closed at the top in such a way that an annular outlet opening 8 remains on the lower electrode.
  • the two outer electrodes 2 and 4 have a jump in diameter at a certain distance.
  • the two single flashover sections 1 combine shortly after the ignition (approximately after 20 microseconds) such that an arc discharge only takes place between the changes in diameter of the two outer electrodes 2, 4 in the area 1 ', the same being pressed magnetically against the center electrode, strongly cooled there and again repelled.
  • a stable arc is formed at a medium distance from the central electrode.
  • hardly any discharge occurs at the gaps between the electrodes or at their edges, so that there is only a particularly small amount of erosion.
  • one electrode spacer is realized with hard gas 6 and the other with mica 6 ', such a surge arrester according to the invention combines a high level of reliability, a long service life and optimal extinguishing behavior for mains after-currents.
  • FIG. 3 shows another exemplary embodiment according to the invention, in which the two disk-shaped electrodes 2, 3 have an insulating piece of the same diameter be kept at a distance from hard gas 6. Due to the one-sided closed hollow cylinder surrounding the two electrodes 2, 3 and their connections 20, 30, which has an annular outlet opening 8 at the bottom and the walls of which are made of hard gas 6f, which produces extinguishing gas under the action of heat from the arc, An overpressure is generated in the chamber 10 upstream of the arc region, which has a favorable effect on the extinguishing of the arc. At a certain distance from one another, the two electrodes experience a jump in diameter and have a further increase in diameter as the distance increases.
  • the arc can develop with increasing current intensity from area 1 between the outer surfaces of electrodes 2 and 3 to the outside (area 1 ').
  • area 1 ' At the jump in diameter, there is now a gap in each of the electrodes, which ensures that the large thermal energy which arises at high currents in the outer arc region 1 'cannot reach the spacer 6 via the adjacent electrode parts and destroy it at an early stage.
  • this gap will not only be filled with air but also with hard gas 6g, as a result of which an increased blowing effect for extinguishing the arc is achieved.
