Definitions

  • the invention relates to an overvoltage protection element for dissipation of transient overvoltages, having two each having a power connection, arranged parallel to each other electrodes, an effective between the electrodes air breakdown spark gap and a housing receiving the electrodes, wherein the electrodes receiving housing closed and pressure-tight and has pressure-resistant and has a cylindrical housing shell and two each provided at one end of the housing shell housing flanges.
  • Such overvoltage protection element is z. B. from the DE 919 056 C known.
  • Electrical, but especially electronic measuring, control, regulating and switching circuits are sensitive to transient overvoltages, as they occur in particular by atmospheric discharges, ie by lightning currents, but also by short circuits and switching operations in power grids can.
  • This sensitivity has increased as electronic components, in particular transistors and thyristors, are used; Above all, integrated circuits that have been used for many years are to a great extent endangered by transient overvoltages.
  • overvoltage protection element from which the invention proceeds that is to say one with an air breakdown spark gap
  • overvoltage protection elements with an air flashover spark gap in which a sliding discharge therefore occurs when responding (cf. DE 27 18 188 A1 , the DE 29 34 236 A1 and the DE 31 01 354 A1 ).
  • Overvoltage protection elements of the type from which the invention proceeds ie those with an air breakdown spark gap, have the advantage of a higher surge current carrying capacity over overvoltage protection elements with an air flashover spark gap, but the disadvantage of a higher - and not very constant - pickup voltage.
  • each electrode has a terminal leg and a sparking horn extending at an acute angle to the terminal leg and form the spark headers of the two - with spaced apart - electrodes together the air breakdown spark gap. It is provided between the opposite ends of the terminal legs of the two electrodes - a triggering a triggering - Zünd Anlagen.
  • the DE 44 02 615 A1 be taken that it is advantageous if the spark horns of the electrodes are provided in their adjacent to the terminal legs areas with a bore.
  • the invention is based on the object to provide an overvoltage protection element of the generic type, which is simple and inexpensive, in a simple manner in its manufacture to different requirements adaptable and is still functional even after repeated response.
  • the overvoltage protection element according to the invention is characterized by the features of patent claim 1.
  • the inventive overvoltage protection element shown in the figures serves to dissipate transient overvoltages and to limit surge currents, in particular lightning impulse currents, as well as to extinguish line sequence currents; Lightning impulse currents up to 100 kA can be derived and Line sequence currents of typically 3 to 4 kA, maximum of 25 kA or even 50 kA, be deleted.
  • the overvoltage protection element according to the invention consists in its essential structure of two electrodes 3, 4 each having a current connection 1, 2, an air-breakdown spark gap 5 acting between the electrodes 3, 4 and a housing 6 receiving the electrodes 3, 4.
  • the electrodes 3, 4 are arranged parallel to one another.
  • the electrodes 3, 4 are arranged side by side; their longitudinal axes thus fall apart.
  • the electrodes 3, 4 are cylindrical; they have a circular cross-section.
  • the electrodes 3, 4 have different cross sections over their length;
  • the electrodes 3, 4 thus have electrode sections 3a, 3b, 3c, 3d and 3e or 4a, 4b, 4c, 4d and 4e.
  • the electrode sections 3c and 4c have the largest diameter. Thus, the smallest distance exists between the electrode sections 3c and 4c, so that the air breakdown spark gap 5 is formed between the electrode sections 3c and 4c.
  • the current connections of both electrodes could lie on the same side.
  • the power terminals 1 and 2 of both electrodes 3 and 4 on opposite sides. They run, as the figures can be easily removed, parallel to each other. Conceivable, however, are embodiments in which the current connections of both electrodes extend at an acute angle to each other.
  • the overvoltage protection element For the functionality of the overvoltage protection element according to the invention, it is of particular advantage if, as the figures do not show, the interior of the electrodes 3, 4 receiving housing 6 is lined, wherein the lining is preferably made of POM Teflon.
  • the illustrated in the figures embodiment of an overvoltage protection element according to the invention is insofar a particularly advantageous, as the electrodes 3, 4 receiving housing 6 is closed and made pressure resistant.
  • the housing 6 receiving the electrodes 3, 4 consists of a cylindrical housing jacket 7 and two housing flanges 8, 9 each provided at one end of the housing jacket 7.
  • the pressure resistance of the housing 6 is realized in connection with an outer pressure cylinder 10 in the above-described construction of the housing 3, the electrodes 3, 4 receiving.
  • the pressure cylinder 10 has a pressure sleeve 11, the pressure sleeve 11 is provided on one side with an external thread 12 and on the other side with an inwardly projecting flange 13, a union nut 14 is provided and the union nut 14 on the Pressure sleeve 11 is screwed.
  • the production of the overvoltage protection element according to the invention is extremely simple and therefore cost.
  • the electrodes 3, 4 the individual parts of the housing 6, namely the housing shell 7 and the housing flanges 8, 9, and the individual parts of the outer pressure cylinder 10, so the pressure sleeve 11 and the union nut 14, it is To rotationally symmetrical parts that are either readily available or can be mass-produced as turned parts on modern machine tools.
  • each housing flange 8, 9 is provided both with a through hole 15, 16, and with a blind bore 17, 18.
  • the thus formed housing flanges 8, 9 thus allow both the passage of the power terminals 1, 2, and - on the other side - an end-side mounting of the electrodes 3, 4, namely in the region of the electrode sections 3e, 4e.
  • an overvoltage protection element is that the housing flanges 8, 9 can be clamped sealingly against the cylindrical housing shell 7, with the help of the outer pressure cylinder 10, namely the fact that the nut 14 is screwed onto the pressure sleeve 11 ,
  • the housing 6 accommodating the electrodes 3, 4 may have air as extinguishing gas; However, it can also be provided with another known quenching gas, for example with SF 6 .
  • the extinguishing gas in which the electrodes 3, 4 receiving housing 6 are under atmospheric pressure but it is also conceivable, in the described embodiment, in which the electrodes 3, 4 receiving housing 6 is designed pressure-tight and pressure-resistant the quenching gas is under a pressure deviating from the atmospheric pressure.
