Definitions

  • the invention relates to a gas discharge surge arrester with two axially opposing main electrodes and a central electrode coaxially surrounding the discharge gap, which is flared at the ends and with the main electrodes via a connecting element and an annular insulating housing, on the inside of which there is at least one line made of electrically conductive material as an ignition line extending over part of the pipe length.
  • Such a gas discharge surge arrester which is also called a two-way arrester, is known from US Pat. No. 4,187,526.
  • two-way arresters with a closely coupled discharge space have the advantage over two single conductors that when a discharge path responds, the common discharge space is ionized and, as a result, the second discharge path also responds without delay.
  • these arresters are used e.g. B. used to protect common in a high-rise news lines (central building).
  • Two-way arresters are known in different designs.
  • ejngangs mentioned there are e.g. B. also a compact version (see. DE-OS-2 828 409, in particular, special Fig. 3).
  • the present invention is therefore based on the object of providing a two-section gas discharge surge arrester which has a high level of constancy in its electrical data during and after exposure to surge current, alternating current and lifetime.
  • a gas discharge surge arrester of the type mentioned at the outset that the main electrodes forming a discharge path are stepped in a double cylinder shape and have an elastic transition to the ends of the insulating housings, that the central electrode forming a main discharge path with the two main electrodes as a hollow cylinder with a tapering tapered profile, at least partially surrounding the two main electrodes and with them the insulating housing is concealed from the discharge paths and that the electrodes made of copper are provided with an electrode activation compound in their overlap area.
  • At least one ignition bar is electrically conductively connected to a main electrode and at least one ignition bar is connected to the center electrode per insulating housing. It has proven to be particularly advantageous to apply two ignition bars in each case.
  • the electrodes can consist of copper, the expansion coefficient of which is not matched to that of the insulating housing, which is expediently made of ceramic.
  • the best life cycle results are achieved with copper by low sputtering.
  • the shape of the electrode allows economical production, namely preferably using extrusion technology.
  • the material costs of copper are significantly lower compared to the Ni-Co-Fe alloys that can also be used.
  • Two-way arresters are often used in sockets that have current loops due to closely parallel feed lines. As a result, the arc burns due to one-sided deflection, preferably at a narrowly limited area of the center electrode edge. This melts and reduces the electrode gap, so that an impermissible reduction in the DC response voltage occurs.
  • the insulating housing with its ignition lines is arranged in a low-vaporization rear space, so that both the good pick-up voltage values and the good insulation with a small residual insulation distance are retained even during service life despite the use of cathode sputtering.
  • Each ceramic insulating body is preferably given two ignition lines which are connected to the main electrode (wire electrode) and two ignition lines which are connected to the center electrode.
