Definitions

  • the invention relates to a spark gap with an ignition circuit and a spark gap arrangement.
  • Lightning protection concepts are known from the normative environment, e.g. DIN EN 62305 (VDE 0185-305:2006).
  • the coarse protection is also referred to as type 1.
  • spark gaps are connected to external trigger circuits, which enable the spark gaps to be ignited at lower voltages.
  • a spark gap with a trigger circuit is known.
  • the trigger circuit has a thyristor that is actively controlled. With active control, an optical control signal is transmitted by means of a semiconductor laser.
  • a spark gap with a trigger circuit is known.
  • the trigger circuit has a spark gap that is actively controlled. With active control, an optical control signal is transmitted by means of a semiconductor laser.
  • gas discharge tubes (abbr. GDT) are often used to provide an insulating gap in the ignition circuit.
  • this ignition circuit arrangement e.g.: with a high-voltage ignition or ignition gaps with a low response voltage.
  • this ignition circuit arrangement e.g.: with a high-voltage ignition or ignition gaps with a low response voltage.
  • gas arresters it may be necessary. to position additional elements such as varistors in the trigger circuit.
  • spark gaps are connected to one another in such a way that they act as a series circuit, at least for individual load cases.
  • the ignition circuits also act like a series circuit. The consequence of this, however, is that the ignition voltages of the ignition circuits connected "in series" essentially have to be added.
  • the protection level can be more than 2 kV in a 230 V/400 V system.
  • references to standards or specifications or norms are to be understood as references to standards or specifications or norms that apply at the time of filing and/or - if priority is claimed - at the time of priority filing. However, this is not to be understood as a general exclusion of applicability to subsequent or superseding standards or specifications or norms.
  • neighboring explicitly includes a direct neighborhood relationship, but is not limited to this.
  • Between hereinafter explicitly includes a position in which the intermediate part is in close proximity to the surrounding parts.
  • a spark gap FS1 according to the invention is, inter alia, in figure 1 shown.
  • the spark gap FS1 will also be referred to below as the first spark gap FS1.
  • the first spark gap FS1 has a first ignition circuit Z1.
  • the first spark gap FS1 has a first main electrode E1 and a second main electrode E2.
  • the shape of the main electrodes E1 and E2 can be suitably selected. There is a free space between the two main electrodes E1 and E2 and the main electrodes are electrically insulated from one another. When a sufficiently high voltage is applied, plasma is formed, during which an electrical connection is established between the main electrodes E1 and E2 and an overvoltage pulse can flow off.
  • the first spark gap FS1 has an auxiliary ignition electrode H1.
  • Such an auxiliary ignition electrode H1 can be arranged at a suitable point between the main electrodes E1 and E2.
  • the auxiliary ignition electrode H1 can be arranged insulated from the main electrode E1 and/or arranged opposite the main electrode E2.
  • the first ignition circuit Z1--outlined by a dashed frame-- has a first voltage-switching element GDT1.
  • the first ignition circuit Z1 is connected to the first main electrode E1 on one side and to the first auxiliary ignition electrode H1 on the other side. Without restricting the generality, the first ignition circuit Z1 has additional elements, as will be explained later in connection with a second ignition circuit Z2.
  • a capacitor C is arranged in parallel with the first voltage-switching element GDT1.
  • the parallel capacitor C means that the voltage present initially only occurs at the other spark gap
  • the second spark gap FS2 (in Figure 2-4 ) is present because the capacitor initially acts as a high-frequency short circuit for the first ignition circuit.
  • the triggering voltages of the individual voltage-switching elements GDT1, GDT2 do not "add up”. Therefore, the second spark gap FS2 is first excited to switch through, with the result that the ignition voltage is now lower than in previous arrangements.
  • the residual voltage which almost corresponds to the original voltage, is now present at the first spark gap FS1 or its first ignition circuit Z1, so that this first spark gap FS1 now switches through with a small delay after the second spark gap is aroused.
  • the effect of “adding” the ignition voltages of the individual voltage-switching elements GDT1, GDT2 does not occur.
  • the series connection is now fully controlled, so that an overvoltage can be discharged here.
  • protection levels below 2.0 kV in particular protection levels below 1.8 kV and even below 1.5 kV to below 1.2 kV can be made available in 230/400 V systems, for example.
  • the first voltage-switching element GDT1 is selected from a group comprising gas-filled arresters, transient voltage suppressor diodes, varistors, PTCs, transistors, and thyristors.
  • the capacitance of the capacitor C is greater than or equal to 9 times the intrinsic capacitance of the first voltage-switching element GDT1 in the idle state.
  • the capacitance of the capacitor C is preferably at least 10 times, better still, 100 times the value of the intrinsic capacitance of the first voltage-switching element GDT1.
  • the capacitor C is soldered to the electrodes of the first voltage-switching element GDT1. In this way, parasitic line inductances that could negatively affect the switching behavior can be avoided.
  • the capacitor C is an SMD (Surface Mounted Device) component. This means that the coordinated circuit can be implemented with little structural effort, so that even in narrow designs safe switching is enabled and existing grid dimensions can be maintained.
  • SMD Surface Mounted Device
  • an insulating material is arranged between the second main electrode E2 and the first auxiliary ignition electrode H1, which leads to a discharge along the surface when a voltage is applied to the first ignition electrode H1, so that the second main electrode E2 and the first auxiliary ignition electrode H1 are electrically conductively connected to one another.
  • Such arrangements are, for example, from the application DE 10 2004 009 072 A1 known to the applicant, see there in particular FIGS. 2a and 2b, the description of which is hereby explicitly referred to.
  • spark gap arrangements of the most varied types can be implemented.
  • the following Figures 2 to 4 be referred, without thereby excluding possible other spark gap arrangements.
  • a spark gap arrangement according to the invention has a first spark gap FS1, as described above, with an associated first ignition circuit Z1. Furthermore, the spark gap arrangement according to the invention has a second spark gap FS2.
  • the second spark gap FS2 has a first main electrode E3 and a second main electrode E4 as well as an auxiliary ignition electrode H2. Otherwise, the previous comments on configurations of the first spark gap FS1 also apply to the second spark gap FS2.
  • the second spark plug FS2 also has a second ignition circuit Z2 with a second voltage-switching element GDT2.
  • the second ignition circuit Z2 is connected on one side to the first main electrode E3 of the second spark gap FS2 and on the other side to the auxiliary ignition electrode H2 of the second spark gap FS2.
  • the second spark gap FS2 is electrically connected to the first spark gap FS1 in the figures between the main electrodes E4 and E1. Between the main electrodes E4 and E1 - as in figure 4 shown - a common conductor - here the neutral conductor N - be arranged.
  • the second voltage-switching element GDT2 is selected from a group comprising gas-filled arresters, transient voltage suppressor diodes, varistors, PTCs, transistors, and thyristors.
  • the second ignition circuit Z2 has a third voltage-switching element VAR, which is different from the second voltage-switching element GDT2.
  • the first ignition circuit Z1 can also easily have a further voltage-switching element that is different from the first voltage-switching element GDT1.
  • first spark gap FS1 and the second spark gap FS2 can be constructed in the same way.
  • first voltage-switching element GDT1 and the second voltage-switching element GDT2 can be constructed in the same way.
  • the first ignition circuit Z1 and/or the second ignition circuit Z2 has an isolating device AE.
  • An isolating device can be implemented, for example, by a prestressed and soldered connection that loses its strength when thermal energy is applied and, under the influence of the prestress, releases the electrical contact through a mechanical separating movement.
  • spark gap arrangement can be used, for example, in an AC voltage system, with the first spark gap FS1 being arranged between a neutral conductor N and a protective conductor PE and the second spark gap FS2 being arranged between a neutral conductor N and a phase, for example L1.
  • the spark gaps can associated ignition circuit can also be used differently.
  • the second spark gap FS2 can be arranged between a neutral conductor N and a protective conductor (PE) and the first spark gap FS1 can be arranged between a neutral conductor N and a phase L1.
  • PE protective conductor
  • the spark gap arrangement can also be used in a 5-wire AC system with 3 phases L1, L2, L3.
