Definitions

  • the invention relates to an overvoltage arrester comprising two electrodes spaced from one another, which form an approach point and at least one spark gap, such as a horn spark gap, which adjoins the proximity point.
  • Such surge arresters are electrically connected in parallel to the consumers to be protected. If an overvoltage occurs between the supply lines, they should be connected with as low an impedance as possible in order to short-circuit the overvoltage and thus prevent it from reaching the consumers.
  • Discharge devices of the type mentioned at the outset are particularly suitable for this purpose.
  • their two electrodes are at a certain distance from one another, at which distance, at a certain height, the voltage present between the electrodes breaks down and becomes conductive in the form of an arc for an overcurrent resulting from the overvoltage.
  • the object of the invention is to provide a surge arrester of the type mentioned at the outset, in which a rapid and reliable interruption of the arc and thus of the line follow current is made possible.
  • This is achieved in accordance with the invention in that at the end of the spark gap opposite the approach point there is at least one electrode element, such as a plate, which at least protrudes into the space delimited by the electrodes of the spark gap and is preferably arranged entirely in this space.
  • the individual arc formed at the approach point is subdivided into a number of partial arcs electrically connected in series. A series connection of a large number of arcs requires a greater total voltage to maintain than a single arc, so that this measure increases the arc-quenching voltage.
  • the electrodes are essentially straight following the approach point and are arranged to form a V-shaped spark gap.
  • Electrodes designed in this way are easy to manufacture and allow the arc-burning path to be widened continuously.
  • the electrodes end in the mutually parallel sections in the end region of the spark gap formed by them. This allows the maximum width of the spark gap to be kept small.
  • the at least one electrode element has the length of the parallel sections and is entirely in the space delimited by the parallel sections. This results in a particularly compact and functionally reliable design.
  • the electrode elements are arranged essentially parallel to one another and optionally parallel to the parallel sections of the electrodes.
  • the length of all partial arcs remains the same during their further movement in the direction of the spark gap end, as a result of which the voltage required to maintain the arcs also remains constant.
  • the electrode elements are arranged pointing in radial directions away from the approach point.
  • the partial arcs are additionally widened during their further movement, as a result of which an additional increase in the arc operating voltage is achieved.
  • all electrode elements have the same length dimensions. The electrode elements can thus be produced in a completely identical manner and therefore inexpensively.
  • Another preferred embodiment of the invention can consist in that all distances between adjacent electrode elements are the same.
  • the energy to be dissipated by the partial arcs is distributed evenly, and all electrode elements can accordingly be constructed and dimensioned in the same way.
  • the electrode elements have different, preferably in pairs, the same length dimensions and protrude at different depths into the spark gap, the electrode elements furthest away from the electrodes preferably projecting deepest into the spark gap. This means that the arc can be split up very soon after it has arisen and can be extinguished relatively early.
  • at least one electrode element protruding into the spark gap extends over the entire length of the electrodes.
  • the electrode elements are formed by circular or rectangular plates. These shapes are relatively simple, for example by means of a stamping process, and can bring about the arc splitting desired according to the invention. In this context, it can also be provided. that the at least one electrode element in the edge region facing the approach point has a V-shaped or Y-shaped cut-out that widens in the direction of the approach point. In the case of electrode elements designed in this way, the transition from the individual arc to the partial arcs is particularly reproducible.
  • the at least one electrode element is formed from a ferromagnetic material.
  • the electrodes are formed at least in regions from a ferromagnetic material, such as iron.
  • the magnetic field generated by the arc current which drives the arc along the electrodes in the opening direction of the spark gap, is amplified by ferromagnetic material, so that the force acting on the arc is also increased and the latter can move faster along the electrodes.
  • a preferred embodiment of the invention can consist in that both electrodes are fixed in place. This type of definition is particularly easy to manufacture, which makes the surge arrester robust and reliable.
  • At least a section of at least one of the two electrodes is movably mounted, in particular pivotable about a pivot axis. Electrodes configured in this way can be moved away from one another when an arc is ignited, as a result of which the arc is expanded and its upright-maintenance voltage increases.
  • an electromechanical actuator is closed in series with the electrodes, which moves the movable electrode section away from the other electrode in the event of an arc being ignited.
  • an overvoltage arrester comprises two electrodes 1, 2 spaced apart from one another, which form an approach point 3 and at least one spark gap 4 adjoining the approach point 3, which is designed as a horn spark gap in the drawings.
  • Their integration in the circuit to be protected against overvoltages takes place in such a way that the first electrode 1 is connected to the feed line and the second electrode 2 to the discharge line of the supply voltage source, that is to say in an AC voltage network to phase and neutral conductors .
  • the spacing of the electrodes means that the discharge device is not conductive, and no current can flow through it.
  • a small capacitive leakage current naturally forms in AC voltage networks, but is negligibly small in comparison to the currents flowing in the downstream load circuits. If a voltage is applied between two conductors, which are arranged at a distance from one another, an electrical field arises between these conductors, the field strength of which depends on the applied voltage. If the applied voltage and thus the electric field is strong enough, the gas located between the conductors is ionized and thus made electrically conductive, which leads to the formation of a relatively low-resistance arc.
  • the surge arrester according to the invention makes use of this physical phenomenon.
  • the approach point 3 of the two electrodes 1, 2 is at a defined distance, which defines the level of the overvoltage necessary for the ignition of the arc.
  • the arc 5 moves in the manner indicated along the spark gap 4 away from the approach point 3, the ionized gases along with the arc 5 and the approach point 3 is again non-conductive.
  • an arc which has been ignited can be maintained by a voltage which is relatively low in comparison with the ignition voltage, so that it remains conductive for the supply voltage of the circuit to be protected and thus draws a relatively high line follow current. If possible, the arc 5 should therefore only exist for the period in which overvoltage is present, but should then be extinguished as quickly as possible.
  • an overvoltage arrester constructed according to the invention has at least one part of the spark gap 4 at the end of the spark gap 4 opposite the proximity point 3, which at least extends into the space delimited by the electrodes 1, 2 of the spark gap 4, as in the embodiments of the drawing figures arranged in this space electrode element 6, such as plate.
  • the two electrodes 1, 2 can have any desired course, but are preferably substantially straight following the approach point 3 and are designed to delimit a V-shaped spark gap 4.
  • the electrodes 1, 2 end in the end region of the spark gap 4 formed by them in sections 40 running parallel to one another.
  • the arc 5 running along the spark gap 4 is divided into a plurality of partial arcs 5 ′, 5 ′′ by the electrode elements 6.
  • the voltage which is necessary to maintain such a series connection of arcs 5 ′, 5 ′′ is higher than that voltage which is required to maintain an individual arc 5 having the same overall length.
  • the arc extinguishing voltage can thus be determined by the number and spacing of the electrode elements 6; it will advantageously have a value equal to the supply voltage or a higher value, so that the discharge device returns to its non-conductive state immediately after the overvoltage has subsided. It is particularly advantageous that a discharge device according to the invention can also be used in DC voltage networks.
  • the arc maintenance voltage is set to a value above the supply voltage by means of a corresponding plate arrangement, so that the supply voltage cannot supply the partial arcs with a sufficiently high voltage.
  • 2a-c shows as an example six electrode elements 6, which have the length of the parallel sections 40 and lie entirely in the space delimited by the parallel sections 40.
  • the electrode elements 6 are arranged essentially parallel to one another and parallel to the parallel sections 40 of the electrodes 1, 2.
  • An overvoltage arrester according to the invention actually installed in a control cabinet can be configured as shown in FIG. 2D.
  • the approach point 3 is arranged directly at the base of the V-shaped spark gap 3.
  • the supply and discharge lines of the supply voltage source are connected to the two electrodes 1, 2 via the connection terminals 25, 26; the rear wall 28 of the housing 27 is advantageously designed so that it can be snapped onto rails usual in switch boxes.
  • the parallel arrangement of the electrode elements 6 described so far is not mandatory, in the embodiment according to FIG. 3a the electrode elements 6 are arranged pointing radially from the approach point 3.
  • an individual arc 5 is divided into a plurality of partial arcs 5 ', which partial arcs 5' are extended by the conically widening plate spacings as the arrow continues to run in the direction of the arrow.
  • the extinction voltage of the partial arcs 5 ′ and thus of the entire lead arrangement is increased again.
  • the heat energies generated in the individual partial arcs 5 ′, 5 ′′ are approximately of the same size, so that the thermal stress and any resulting signs of wear are evenly distributed over the individual electrode elements 6.
  • 3b shows an example of electrode elements 6 with different length dimensions.
  • the electrode elements 6 are again arranged parallel to the sections 40 at a constant distance from one another, but they have the same length dimensions in pairs and project into the spark gap 4 at different depths.
  • the electrode elements 6 which are furthest away from the electrodes 1, 2 extend the deepest into the spark gap 4, and are therefore arranged with their first ends closest to the approach point 3.
  • the individual arc 5 is gradually broken down into a number of partial arcs 5 '.
  • FIG. 3c shows an embodiment of the invention in which two approximation points 3 are arranged parallel to one another.
  • the diverter device according to FIG. 3d is essentially similar to the embodiment according to FIG. 2, but in contrast to this has an electrode element 6 ′ protruding into the horn spark gap 4, which extends over the entire length of the electrodes 1, 2 and thus also protrudes into the approach point 3.
  • two partial arcs 5 ′ are formed when the discharge device is ignited, which are then subdivided into a number of further partial arcs.
  • Embodiments of the invention which have only one horn spark gap 4 have been explained so far.
  • any number of spark gaps can reach the approach point 3 4 connect, preferably two or four spark gaps 4 are formed in the form of horn spark gaps.
  • 4a-c show examples of two such spark gaps 4.
  • the electrodes 1, 2 in turn have an approach point 3, which is designed such that two arcs can form in parallel, and are further developed in two directions, which directions preferably include an angle of 180 ° to one another, in the form of horn spark gaps 4.
  • 4b an electrode element 6 ', which extends over the entire electrode length and projects into the approach point 3, can also be provided here. As shown in FIG. 4c, this electrode element 6 'does not have to be designed continuously, but can have an interruption 6''in the area of the approach point 3'.
  • the electrode elements 6 can also be arranged here according to the embodiments according to FIG. 3a (fan-like) or FIG. 3a (step-like).
  • 5 shows an example of an embodiment with four horn spark gaps 4.
  • the principle of operation corresponds to the arrangement forms described above, here the electrodes 1, 2 continue in four directions, each enclosing 90 ° to one another. It is expedient if the electrodes are formed at least in regions from a ferromagnetic material, such as iron, because this increases the force driving the arc. In contrast, however, it is better to let the arc run or burn on an electrically conductive material, in particular on copper.
  • the electrodes 1, 2 consist of copper, but are deposited with a ferromagnetic material.
  • iron coated with copper could also be used as the electrode material.
  • Any electrically conductive material which also withstands the thermal stresses occurring when an overvoltage is dissipated can be considered as material for the electrode elements 6. Copper-tungsten alloys can be cited as an example of such materials.
  • all of the embodiments discussed so far are further common that the two electrodes 1, 2 are fixed in place.
  • At least one section 1 'of at least one of the two electrodes 1, 2 is movably mounted, in particular pivotable about a pivot axis 7, as shown in FIG. 6a. With such a movable mounting of one or both electrodes 1, 2 or sections 1 ′ of the electrodes 1, 2, these movable parts are actually moved away from one another (cf. dashed line of section 1 'in its position remote from electrode 2).
  • the already burning arc 5 is expanded rapidly, so that the voltage required to maintain it is increased very soon after it has arisen.
  • a resetting device which is designed as a leaf spring 10 in FIG. 6 a
  • the movable section 1 can be automatically brought into its rest position after the arc has been extinguished, so that the diverter device is ready to discharge the next overvoltage.
  • the reset device could, however, also be omitted, so that the movable section must be brought into its rest position by hand. If the force effects caused by the overcurrent are too small to bring about the movement described, then, as shown in FIG.
  • an electromechanical actuating element 30 can be provided per movable electrode section 1 ', which is connected in series with the electrodes 1, 2 is closed and moves the movable electrode section 1 'away from the other electrode 1, 2 in the event of an arc 5 being ignited.
  • the electromechanical actuator 30, in the example shown a conventional magnetic release, has a coil 11 which is connected on the one hand via an electrical line 12 to the movable electrode section 1 'and on the other hand via an electrical line 13 to the first supply line.
  • the coil 11 is wound around a sleeve 14 within which an armature 15 is movably received.
  • the sleeve 14 with the coil 11 is fixed in a yoke 16.
  • the armature 15 is connected to the movable electrode section 1 'via a tension element 17, which can be, for example, a thin rope or a rod.
  • a compression spring 19 is arranged between the leg 18 of the yoke 16 facing the movable electrode section 1 'and the movable electrode section 1', which, as shown in the drawing, is supported on the support 20 on the leg 18 of the yoke 16. Both the movable electrode section 1 'and the armature 15 are always moved back into the starting position by the compression spring 19 after the arc 5 which arises when the overvoltage is dissipated has extinguished.
  • FIGS. 6a, b can, however, be expanded in such a way that both electrodes 1, 2 are movably supported, at least in sections.
  • FIGS. 7 a, b Corresponding examples can be found in FIGS. 7 a, b.
  • the pivotable mounting of the electrodes 1, 2 or the electrode sections 1 ', 2' is also not mandatory, alternatively the movable parts could be moved in parallel along a rail arrangement 22 by means of the actuation options mentioned (see FIGS.
  • the electrode elements 6 protruding into the horn spark gap 4 can have any shape. Examples of this are given in FIGS. 9a-f. However, the shapes shown in FIGS. 9d-f are particularly preferably used, in which the electrode element 6 has a V-shaped or Y-shaped, has a widening 60, 61 in the direction of the approach point 3.
  • the ambient atmosphere of the two electrodes 1, 2 is in no way restricted. Although it preferably consists of the natural ambient air, it could also be formed by vacuum, noble gases, tritium, SF 6 or the like.
