Definitions

  • the invention relates to a lightning current carrying Spark gap with several series connected Spark gaps.
  • a line follow current flows at line frequency and one Height from a few kA to a few 10 kA, depending on the Distance of the building from the next Transformer station and the feed-in power.
  • the upstream fuse becomes the three-pole Disconnect the short circuit from the mains, causing the Power supply fails. It can only be replaced the main network fuse by the Energy supply company back in operation be taken.
  • spark gaps To avoid damage due to lightning strikes in spark gaps are known in a building. Such Spark gaps become transient Equipotential bonding used, the subsequent line follow current is deleted. All previous solutions are based on the fact that Spark gap ignited during a lightning surge the lightning current between earth and conductor to Ensuring a low voltage drop along of the arc is derived or guided, the Mains sequence current is conducted and deleted and a The spark gap is reconsolidated.
  • the spark gap capable of carrying lightning current according to the invention is based on the basic idea of arc quenching Multiple interruption of the arc with the help of a Multiple spark gap.
  • the voltage drop on the anodes and cathodes of the partial spark gaps Multiple spark gap for arc quenching and This prevents the follow-up current exploited.
  • the extinguishing effect can be done in the usual way can be increased in that the spark gap in one sealed housing is installed.
  • the Quenching can also be done by blowing the arc be increased with cold gas.
  • the arc is divided into multiple arcs.
  • the proposed multiple spark gap uses the effect of dividing the arc into several partial spark gaps, so that the anode and cathode drop (voltage drop, in particular at the arc base points on the anode and cathode) of the individual spark gaps is added.
  • n is the number of spark gaps of the multiple spark gap and U AK is the anode or cathode case of a partial spark gap of the multiple spark gap.
  • the formation of the first spark gap is decisive for the responsiveness.
  • On the chain of Spark gaps become the tension of each Partial arcs added up so high in total that they is higher than the mains voltage, so that actually none Mains sequence current arises.
  • the multi-spark gap can also be used with a Sliding discharge arrangement for reducing the Ignition delay time of the partial spark gaps in combination with the corresponding resistor circuit be equipped.
  • the sliding discharge arrangement exists from a arranged along the spark gaps Layer of an insulating material, in which a metallic Film or the like is let in on Earth potential is.
  • the electrodes of spark gaps from metals such as copper, tungsten copper or the like Metals after exposure to high Lightning currents on the surface Meltings show that there is metallic vapor on the surface of adjacent insulation arrangements precipitates. These effects reduce the Lifespan of such a spark gap.
  • an electrode made of graphite suggested.
  • the partial spark gaps of the Multiple spark gaps are therefore preferably made Made of graphite. Because of the low metal burn-up when exposed to lightning currents up to 200 kA graphite is particularly suitable for this application. Even after repeated exposure to lightning impulse currents remains the surface of the electrodes of the Multiple spark gap clean and keeps its shape. This ensures that the response voltage of the Spark gap remains within the permissible spread.
  • the spark gap is preferably made of cylindrical or cube-shaped electrodes built up by an insulating film or washer heat-resistant material, in particular PTFE or Ceramics, insulated from each other.
  • By appropriate designs of the Parallel plate spark gap, for example with large area electrodes, will be a big one created field-filled volume, from which Voltage stress on the starting electrodes to be provided. By the enlarged field-filled volume becomes the response voltage and their scatter significantly reduced.
  • a spark gap is shown in FIG a head of the power supply network and at II an earth is connected.
  • the Partial spark gaps FS2 to FSN with the exception of those in Lightning current event first appealing Spark gap FS1 through a graded network of ohmic resistors connected, so that Partial spark gaps FS2 to FSN successively switch through.
  • the network of resistors shows in Switching direction decreasing resistance values. So
  • the resistance R2 can be 10 kilohms Resistor R3 1 kilohm, resistance R4 100 ohms, the Resistor R5 10 ohms and resistance Rn X ohms exhibit.
  • the resistors can preferably decrease logarithmically.
  • a resistor R2 to Rn connected in parallel and the resistances of all Partial spark gaps R2 to Rn are in series on earth (II) switched.
  • spark gap electrodes 2 made of graphite are provided, that by insulating washers made of PTFE from each other are spaced.
  • At 4 is a connection of one Control resistor shown.
  • With 5 is a housing shown, which surrounds the entire unit.
  • At 6 is the power connection shown.
  • the control resistors 10 are also in one protected space inside the insulating housing arranged. With 11 is another insulating material plate shown. With 1 contact springs are shown, by means of which is the contacting link to the Spark gaps take place.
  • the electrodes 2 of the Spark gaps are preferably cylindrical or cuboid, sharp-edged elements. In the Embodiment according to Figure 3 is the entire Spark gap from two arranged parallel to each other Blocks of the same number of partial spark gaps.
  • the Sliding discharge ignition aid consists of a longitudinal arranged parallel to the spark gaps FS1 to FSN Layer 12 of insulating material, for example PTFE, in which is a metallic conductor 13, in particular one metallic foil, is embedded. This slide is at 14 connected to earth potential.
  • This slide is at 15 there is one Sliding discharge shown as the first pre-discharge ignites before the main discharge 16 as a result of first sliding discharge ignites.
  • the spark gaps FS2 to FSN are included Control resistors R2 to Rn connected.
  • the distance between the first spark gaps is FS1 decisive for the response behavior of the Total spark gap.
  • FSN farnesoid voltage
  • the invention is not based on the embodiment limited, but often within the scope of the disclosure variable.
