Definitions

  • the invention relates to a horn spark gap with a non-blowout deion chamber with an insulating housing as a support and receiving body for the horn electrodes and the deion chamber, and means for guiding the gas flow caused by the arc according to the preamble of claim 1.
  • the DE 10 2011 102 257 A1 shows a horn spark gap with deion chamber in non-blowing design, which consists of a multi-part insulating material housing.
  • the horn electrodes and the deion chamber are located in the insulating housing. Means for guiding the gas flow caused by the arc are also present.
  • the insulating material housing there is divided in the plane spanned by the horn electrodes and forms a first and a second half-shell.
  • the horn electrodes are implemented asymmetrically.
  • the arc running area between the electrodes is limited in the direction of the deion chamber by a plate-shaped insulating material.
  • the known horn spark gaps are particularly suitable for deriving high lightning impulse currents, but also for limiting and extinguishing large network follow currents.
  • it has already been possible to integrate previously known horn spark gap arrangements with deion chambers in modular installation devices it is problematic to further improve the discharge capacity or the follow-up current extinguishing capacity by simple series or parallel connections.
  • a conceivable arrangement of several horn spark gaps with quenching or deion chambers in a DIN rail housing definitely requires more space and is costly due to the duplication of the individual components.
  • the arcs that occur when the spark gaps are ignited are affected that a desired, reproducible deletion behavior is not guaranteed under all conceivable conditions.
  • a horn spark gap with a deion chamber preferably of a non-blowing design
  • the horn spark gap is located in an insulating material housing, which serves as a support and receiving body for the horn electrodes and the deion chamber.
  • Means for guiding the gas flow caused by the arc are also present. These means can special deflecting elements such as Splinters, but also targeted openings and recesses in the interior of the housing.
  • the horn electrodes of a pair of horn electrodes have an asymmetrical shape, namely a longer and a shorter electrode. In a preferred embodiment, both electrodes are formed almost parallel and with a low divergence in the ignition area.
  • the arc running area between the electrodes is limited in the direction of the deion chamber by appropriate design measures.
  • the housing has formations which accommodate a central deion chamber part or two separate deion chamber parts, openings or openings being provided in the housing and the electrodes leading to the respective deion chamber part, so that the gas flow at least partially reaches the respective deion chamber.
  • the housing can have a sandwich structure and consist of half shells.
  • At least two horn spark gaps in the housing which have separate electrical connections for optional series or parallel connection of the spark gaps integrated in the housing.
  • a partition is formed within the housing in order to achieve a separation of the arc combustion chambers and to enable a gas flow to move the arc base.
  • the horn spark gaps are preferably formed adjacent to one another in one plane. According to the invention, the arrangement of the horn spark gaps with corresponding horn electrodes is mirror-symmetrical.
  • the deion chamber comprises, in a manner known per se, a multiplicity of spaced-apart individual sheets, which in one embodiment can have a V-shaped notch, the V-opening of which is directed towards the horn spark gap in order to determine the choice of the distance between the individual sheets and / or an additional insulation Set or specify the flow resistance in the inlet area of the deion chamber.
  • the deion chamber is also preferably mirror-symmetrical with openings V-shaped on both sides, and in the first embodiment the partition is arranged to run over the axis of symmetry.
  • the deion chamber can have ventilation openings, the number, size and shape of which allow the flow resistance in the inlet area to be set or predefined.
  • a trigger electrode can be arranged in the ignition area, the trigger electrode being able to comprise a conductive element which is surrounded by a sliding distance or has adjacent sliding distances.
  • the partition can therefore be arranged between two back-to-back deion chambers according to the above description of the first embodiment.
  • the horn spark gap with a deion chamber for arc quenching within the insulating material housing is designed such that measures are taken to set a different behavior of the arc arising from a pulse current load on the one hand and the arc sequence-related arc on the other hand, for this purpose the distance between the opposite electrode surfaces of the horn spark gaps in the ignition area is kept narrow and the arrangement of the opposite electrode surfaces in the ignition area a slight increase in distance towards the end the horn spark gap.
  • the distance between the opposite electrode surfaces in the ignition area can be ⁇ 1.5 mm and is preferably in the range between 0.3 mm and 0.8 mm.
  • gas circulation is provided in such a way that the pressure wave generated by the lightning pulse current-induced arc is reflected by the deion chamber and / or flow obstacles and counteracts the arc movement and the gas flow which passes through the deion chamber is at least partially directed back to the ignition area via deflection means and is led to flow openings present in the electrodes.
  • the horn spark gap according to the invention with a deion chamber is designed such that it forms a universal module with external connection terminals for the electrodes, the module being integrable into a plug-in part or external housing known per se, depending on the customer's requirements.
  • the horn spark gap module can be arranged directly on a wiring carrier, in particular a printed circuit board.
  • means can therefore be provided for influencing the arc and its running behavior due to gas flow.
  • means for magnetically blowing the arc can be increased immediately after it is ignited by a combination of measures to strengthen the arc-related magnetic field and a staggered gas circulation of the arrester, with the electrodes in the running area of the arc having the aforementioned recesses in this sense which the gas flow enters the interior of the arc chamber to support the arc movement.
  • two spatially separated deion chambers are provided in the housing, the opening areas of the horn electrodes or the respective pair of horn electrodes pointing away from one another and leading to the respectively assigned deion chamber.
  • This embodiment also has a fundamentally symmetrical structure and there are separate electrical connections for optional series or parallel connection of the horn spark gaps integrated in the housing.
  • the deion chambers are located on two side walls opposite one another in the interior of the housing.
  • the ignition areas of the horn electrodes are arranged on both sides of an axis of symmetry.
  • a partition wall, as mentioned in the first embodiment, can be dispensed with.
  • Corresponding individual sheets forming the deion chamber 3 are used in a known manner in the insulating housing 4, openings or openings (not shown) being provided in the interior of the housing for maintaining a targeted gas flow, and in this regard further insert parts such as e.g. Splinters, deflection means or the like can be arranged depending on the design of the horn spark gap.
  • the opening areas of the horn electrodes 1; 2 lead to the respective assigned deion chamber 3.
  • the ignition areas Z are arranged closely adjacent to an axis of symmetry S in a central area and are not, as in FIG Figure 1 shown, away from the axis of symmetry S in the housing edge areas.
  • the electrodes 1; 2 of the respective horn electrode arrangement can consist in a simple manner of stamped and bent parts and at the same time via molded connections A1; A3 dispose, which lowers the manufacturing costs of a related surge arrester.
