Definitions
- the invention relates to an overvoltage protection element for the derivation of transients Surges, with two electrodes, one effective between the electrodes Air breakdown spark gap and a housing that receives the electrodes, where each electrode has one lead leg and one at an acute angle the associated connecting leg has a spark horn and between the spark horns of the two electrodes, spaced apart from each other the air breakdown spark gap is formed.
- Surge protection elements of the type from which the invention is based that is to say those with an air breakdown spark gap, now have overvoltage protection elements with an air flashover spark gap the advantage of a higher one Surge current carrying capacity, but the disadvantage of a higher one - and not particularly constant - response voltage.
- a third teaching after the aforementioned older patent application has and essentially to the content that the housing is at least partially made of a plastic exists that does not give off carbon during combustion, or at least is partially lined with such a plastic.
- the installation of electrodes forming an air breakdown spark gap with spark horns in a relatively small, plastic, which when heated or burned Releases carbon existing housing is problematic. In particular it happens due to the very hot arc that arises after the response Combustion of the plastic and thus an enormous release of carbon. This leads to the electrodes becoming dirty and no longer having insulation strength is available.
- the enormous amount of carbon in the Gas mixture the extinguishing behavior of the electrodes.
- the disadvantages described above of course do not occur if the housing is at least partially made of one Plastic consists of no carbon when heated or burned emits, or if the housing at least partially with such a plastic is lined.
- a fourth teaching after the aforementioned older patent application has and essentially to the content that the side walls of the housing are relatively close to the spark horns of the electrodes are used.
- One enters through this teaching extraordinarily good atmospheric blowing of the arc. It runs very well quickly to the tips of the spark horns, so it does not get stuck in the ignition area.
- the spark horns of the electrodes Adjacent housing cover made of electrically conductive material, preferably made of There is copper tungsten, the distance between the Housing cover adjacent ends of the spark horns of the electrodes and the housing cover is chosen so that between the ends adjacent to the housing cover arcing can occur between the spark horns and the housing cover.
- the arc initially migrates out of the Ignition area at the tips of the spark horns. Then form between the tips the spark horns and the housing cover made of electrically conductive material two arcs. The conductor loop that builds up ensures that that the two arcs are driven behind the spark horns.
- the present invention is based on the object of a surge protection behavior again improved surge protection element specify.
- the surge protection element according to the invention is now characterized in that that the air breakdown spark gap bent and / or angled is and that the spark horns are each approximately at right angles to the connecting leg trending straight lower area and one on the straight Have area adjacent arcuate upper area.

- the air breakdown spark gap between 10 ° and 180 °.
- movement of the arc to the tips of the spark horns results then when the air breakdown spark gap is bent by about 90 ° and / or is angled.
- the lower region of the air breakdown spark gap an angle of about 10 ° to 40 °, preferably of includes about 20 ° to 30 ° and the two areas of the spark horns essentially smoothly merge.
- the air breakdown spark gap opens directly into a blow-out opening in the housing, so that the resulting exhaust gases can be blown out directly and not in the housing knock down.
- a quenching plate arrangement having a plurality of quenching plates is provided.
- the surge protection behavior, in particular the line follow current quenching behavior improving effect of the quenching plate arrangement is based on the fact that the arc is arranged in a series of short, partial arcs is resolved and that the sum of the partial arcs is higher Voltage requirement than the undivided arc, so that after the voltage zero a higher re-ignition voltage is required than with an undivided arc.
- the quenching plate arrangement in or following the air breakdown spark gap is arranged in the region of the blow-out opening. Hereby the arc runs almost directly into the quenching plate arrangement.
- extinguishing plates made of ferromagnetic material preferably made of iron.
- the creation of the forces that cause the arc in the Extinguishing sheet arrangement drives in, explained when using extinguishing sheets made of ferromagnetic material from the endeavor of the one through which current flows Conductor surrounding magnetic flux, if possible through the magnetic much better to run as air-conducting iron quenching plates; the arc is therefore from a quenching plate arrangement, the quenching plates made of ferromagnetic material exist, attracted.
- the surge protection element according to the invention Has baffle plates, it is preferably around rectangular baffle plates, the baffle plates having a cross section with a length to width ratio of about 4: 1 to about 2: 1, preferably of about 3: 1.
- the blow-out opening drain the opposite exhaust opening in the housing. Accordingly the larger spark horn is designed so that it creates the resulting exhaust gases on the one hand leads in the direction of the blow-out opening, on the other hand an outflow into Direction of the exhaust opening allows.
- the exhaust opening - is the danger that the exhaust gases are inside the housing precipitate and thereby the function of the surge protection element have been significantly reduced.
