Definitions
- the invention relates to a surge arrester consisting of a gas, in particular air spark gap with a spacer for the electrodes consisting of insulating material and a chamber adjoining the area of the arc discharge, the walls of which are formed by the two electrodes and the spacer.
- Such surge arresters are known, for example from the article "Protection of electronic and communications systems by means of spark gaps" from bark-Elektronik 4-1979, pp. 127 to 130.
- the spark gaps described in this article are usually two- or three-electrode spark gaps with one hermetically sealed gas filling.
- Such spark gaps are suitable for protecting telecommunications cables or receiving antennas against lightning flashovers, but they only suffice for operational insulation, but not the increased requirements for protective insulation.
- an overvoltage protection for telecommunications lines which consists of a spark gap between two carbon electrodes, with a region being provided around the area of the arc discharge, which serves as an outlet for particles that pass from the electrodes into the Break out the arc gap.
- This spark gap also only suffices for operational insulation and, moreover, has a very limited service life.
- the object of the invention was therefore to provide a surge arrester of the type mentioned at the outset, the insulation resistance, the dielectric strength and the reliability thereof in the non-ignited state of the protective insulation according to VDE regulation 0845 are equivalent, the response voltage is lower than the dielectric strength of the protective insulation, that in the ignited state the voltage is limited to non-hazardous values and which can take up the full lightning current several times without its functions being impaired to such an extent that the above-mentioned requirements are no longer met by vaporizing the spacer relevant for the protective insulation with electrically conductive plasma particles and thus Decrease in its insulation resistance is prevented or inhibited.
- the surge arrester according to the invention has the advantages that high leakage currents can be dissipated through it, that there is high dielectric strength, high reliability and high insulation resistance in the non-ignited state and that these properties are retained even after many strong lightning loads.
- the surge arrester therefore fulfills the basic requirements for protective insulation, provided that its response voltage is correspondingly lower than the dielectric strength of the protective insulation, which can be achieved with known means.
- a suitable combination with arresters which meet the requirements for operational insulation and which can automatically extinguish the arc of the mains current after ignition by an overvoltage in accordance with the requirement of VDE 0675 Part 1, according to the patent .
- the surge arrester according to the invention can thus fully meet the requirements for protective insulation, which are neither additional grounding or potential equalization measures required (see patent . « (application P . «, BK 79/55, registered by DEHN + S ⁇ HNE and AEG-TELEFUNKEN AKTIENGESELLSCHAFT, registration priority as the present application)).
- FIG. 1 shows an advantageous embodiment of the invention, namely a rotationally symmetrical arrangement of the perforated disk-shaped electrode 1 and the fully cylindrical electrode 2 arranged underneath with a chamfered inner or outer edge 8.
- the area 3 of the arc discharge which is in the unignited state is gas, preferably air insulated.
- the spacer 4 between the outer edge of the disk-shaped lower extension of the electrode 2 and the outer edge of the electrode 1 is far from the area of the arc discharge.
- the pressurized arisen during the arc discharge For the most part, gases can escape upwards into the open. However, it cannot be avoided that a smaller part of the gases is pressed into the chamber 5 formed by the electrodes and spacers.
- This chamber is labyrinthine in such a way that an artificial extension of the path of the gases to the spacer and cooling takes place.
- This has the advantage that the evaporation of the inner surface of the spacer is prevented by metal particles torn out of the electrodes during the arc discharge, or can be carried out very slightly, which is an essential prerequisite for permanent and unrestrictedly effective protective insulation.
- the cooling is carried out by the heat-dissipating metal walls of the labyrinth, which are insulated on the electrodes 1 and 2 in order to prevent the arc discharge from spreading to the labyrinth area (6, 7).
- Such a labyrinth arrangement makes it possible for the gases generated during the arc discharge to be able to be deposited on the labyrinth walls for the most part, so that the insulation value of the spacer and thus the spark gap does not deteriorate significantly even after many heavy lightning current stresses.
- a suitable electrode material for example tungsten copper, which has a high resistance to burnout, the wear can advantageously be kept very low.
- the arc can be held stably in the air gap provided for this purpose and thus also a vaporization of the distance insulator can be counteracted.
- the right half of Figure 2 shows another embodiment of the invention.
- the lower electrode 2 protrudes with its end face 9 and its outer lateral surface 10 far into the opening of the hollow cylindrical electrode 1, so that the arch relief in region 3 can unfold between the opposite parts of the cylindrical lateral surfaces 10:
- the labyrinth 5 is Phase surface 8, from the end surface 9, from the outer lateral surface and from the lower part of the disk-shaped extension of the electrode 1 adjoining the upper end of the hollow cylinder, and from metal walls 7 which are attached to a disk-shaped insulating body 6a surrounding the electrode 2, and formed by the outwardly delimiting spacer 4.
- FIG. 2 shows the cross section through another surge arrester according to the invention, in which the end faces 9 of the two cylindrical electrodes 1 and 2 enclose the area of the arc discharge.
- This arrangement keeps the discharge particularly stable, so that the spacer 4 can be vaporized even less.
- the well-formed labyrinth 5 consists of three chambers which surround the electrode 2 by three metal walls 7, one in the form of a disk Send insulating piece 6a, on which two of the metal walls 7 are attached, and an insulating piece 6, with which the third metal wall is attached to the upper electrode 1, are formed.
