Definitions
- the invention relates to an arrangement for igniting spark gaps with a trigger electrode located on or in one of the main electrodes and insulated from this main electrode, the trigger electrode being electrically connectable to the further main electrode via at least one voltage-switching or voltage-monitoring element and between the main electrode and the further There is an air gap in the main electrode, the trigger electrode with an insulation layer and a layer made of a material with a lower conductivity than the material of one of the main electrodes forms a sandwich structure, the insulation layer is formed as a thin film or lacquer layer and the layer with the material with lower conductivity one of the main electrodes is in contact or rests on this according to the preamble of claim 1.
- Spark gaps can be differentiated in terms of their behavior as breakdown or sliding spark gaps. Such spark gaps
- Trigger electrode The ignition in the case of triggered spark gaps is carried out either by using an ignition transformer with the consequence of a high response voltage of the correspondingly well-insulated trigger electrode or, in an alternative, by a special arrangement of the
- Triggered spark gaps generally have a controllable response behavior.
- a conductive housing is provided there directly to form a Partial spark gap a trigger voltage can be applied in the discharge space.
- the main spark gap between the main electrodes is ignited via the partial spark gap.
- An ignition transformer which is part of the trigger device, is also used there.
- ignition transformers require a not inconsiderable installation space.
- the size of the ignition voltage generated in the ignition transformer on the secondary side depends on the primary-side current change di / dT. If such a current pulse does not have a sufficient steepness, the voltage occurring on the secondary side is not sufficient to achieve the
- an ignition transformer can be omitted.
- a sliding discharge is triggered between one of the main electrodes and the trigger electrode during the ignition process, which reaches the further main electrode after a certain time and triggers the ignition process.
- Such trigger electrodes have permanent electrical contact with one of the two main electrodes. This means that there is no electrical isolation of the main potentials. For this reason, a voltage-switching element, for example in the form of a
- Gas discharge tube can be switched.
- the generic solution has a trigger electrode, which has an insulation layer and a layer made of a material with a lower conductivity than the material of one of the main electrodes
- the insulation layer is preferably designed as a thin film or lacquer layer.
- the layer of material less Conductivity is in contact with or on one of the main electrodes.
- the layer dielectric of the sandwich structure turns out to be one
- the partial capacities are chosen to be very low.
- the material M of the sandwich structure has a much worse one
- the ignition arc is lengthened over the thickness of the layer of material M.
- the thin insulation gap between the trigger electrode and the layer of poorly conductive material can preferably be realized by printed circuit boards.
- the trigger electrode then corresponds to the applied conductor track and the insulation layer to the lacquer layer above, with an end section remaining free of lacquer layer.
- the plasma jet effect explained above is characterized by the expression of a preferred direction of the ionized gas flow.
- measures can be taken which on the one hand influence the formation of the beam, but also the direction, so that the effect of a rapid ignition of the main line arises.
- the proposed beam with its very effective ionization of air distances is used to overcome the air gap between the main electrodes particularly suitable, which in turn ensures effective operation of the preferred horn spark gap. Due to the electrode arrangement and the insulation layer and the layer made of the material with lower conductivity, a preferred orientation is otherwise only stochastic
- the material with a lower conductivity can be suitable for gas emission, which enables a further targeted generation of the plasma jet.
- the solution according to DE 10 2011 102 937 Al offers the advantage of a very fast ignition of the main spark gap compared to classic, non-insulated current triggering methods, as a result of which all other components of the spark gap arrangement are subjected to less energy and can therefore be designed in a miniaturized manner.
- a disadvantage is the fact that even the smallest, relatively low-energy pulses from overvoltage events are sufficient to ignite the entire spark gap. This results in a possible disadvantageous aging of the corresponding surge arrester arrangement.
- a trigger electrode located on or in one of the main electrodes and insulated from this main electrode.
- the trigger electrode can be electrically connected to the further main electrode via at least one voltage-switching or voltage-growing element.
- the trigger electrode forms a sandwich structure with an insulation layer and a layer made of a material with a lower conductivity than the material of one of the main electrodes.
- the insulation layer is preferably a thin film or lacquer layer
- the layer made of the material of lower conductivity is in contact with or lies on one of the main electrodes.
- the arrangement is now developed in such a way that an energetic limit or an energetic threshold value can be defined, energetically weak overvoltage events being derived below the defined limit or threshold value without the spark gap responding between the main electrodes. If the limit or threshold value is exceeded, the correspondingly triggered derivation process takes place by igniting the main spark gap.
- the insulation layer of the sandwich structure is interrupted outside of the ignition area in order to discharge weakly energetic overvoltage events without responding to the spark gap formed between the main electrodes.
- an electrical component influencing the response behavior is integrated between the trigger electrode and the main electrode in the spark gap.
- the interruption of the insulation layer forms an electrical connection between the trigger electrode and the layer of lower conductivity, the derivable energy content of the .through the limited conductivity or the resistance of the layer of lower conductivity
- Overvoltage event can be determined. This in turn allows the aforementioned limit or threshold value to be set.
- the aforementioned electrical component is an integrable, miniaturized resistor.
- Burst pulses generally no longer lead to the ignition of the entire spark gap, since the low or minimal pulse energy is reduced in the layer of lower conductivity.
- the degree of deceleration can be influenced via the structural design and the material sizes or material properties.
- the ignition auxiliary spark gap is ignited by a flashover of the insulation gap in the
- the trigger electrode is a
- the conductor track of a film circuit board and the insulation layer are formed by an insulating cover, in particular a lacquer layer on the conductor track.
- the insulating cover is exposed for the interruption, so that the exposed section of the conductor track can be connected to the layer of lower conductivity.
- the layer of lower conductivity can preferably consist of a conductive plastic material or of a material with a
- Carbon fiber content are formed.
- Fig. 1 is an equivalent circuit diagram with the basic arrangement of
- Main electrodes of a spark gap and a sandwich structure comprising a trigger electrode with an insulation layer and a layer made of a lower material
- Fig. 2 is a representation similar to FIG. 1, but with a hinted
- Energy contents of an overvoltage event can be directly derived without responding to the total spark gap.
- FIGS. 1 and 2 comprises an electrically conductive trigger electrode T which extends from an insulation layer I in the direction of the
- Main electrode H2 is covered.
- the insulation layer I is followed by a layer made of a material M with a lower conductivity.
- the layer of material M lies on the surface of the second
- connection A external elements can be connected between trigger electrode T and the main electrode H1.
- the funds provided there can for example include gas arresters, varistors, diodes or similar electrical components.
- the spark gap formed by the main electrodes Hl and H2 can be used as a spark gap
- Horn spark gap can be formed and is electrically connected between the paths L and N / PEN.
- an electrical component R influencing the response behavior is connected between the trigger electrode T and the main electrode H2.
- the value of the resistance R determines that
- the thin insulation layer I is interrupted outside the ignition and flashover area, so that the trigger electrode T is conductively connected to the material of lower conductivity M.
- the energy content of the overvoltage is so low that only a very small current flows and the voltage drop in the poorly conductive material M is not sufficient to flash over the insulation layer I. This means that the rollover range does not respond and the overvoltage is derived solely from the energy mapping range.
- the layer of material M not only has the task of extending the ignition arc by extending the direct flashover distance from the trigger electrode T to the main electrode H2, but rather the resistance value of the poorly conductive material via the contacting of the trigger electrode with the Layer M used to derive weak surge events.
- This configuration makes it possible to completely dispense with any separate electrical or electronic components for controlling the response behavior, in particular in the case of very weak overvoltage events.
