Definitions

  • the invention relates to a switching device having a first conventional switching point, a second conventional switching point and a non-conventional switching point.
  • Such a switching device is for example from the published patent application DE 10 2011 005 905 A1 known. There, a switching device is described which, as conventional switching points, has a gas-insulated circuit breaker and a vacuum circuit breaker. A device for generating a countercurrent, which has a thyristor, is provided electrically in parallel with the vacuum circuit breaker. The device for generating a countercurrent is a non-conventional switching point in terms of its structure. Another such switching device is from the document EP 2 469 652 A2 known.
  • the known switching device is particularly suitable for switching direct currents.
  • a counter current is impressed on the direct current to be interrupted by means of the device for generating a counter current in order to interrupt it.
  • the invention is achieved in a switching device of the type mentioned in the introduction in that the first conventional switching point, the second conventional switching point and the non-conventional switching point form a series connection with one another.
  • Non-conventional switching points are switching points which bring switching contact pieces which are movable relative to one another into galvanic contact in order to produce an electrically conductive current path and conversely remove switching contact pieces which are movable relative to one another during an interruption of a current path in order to allow an electrically insulating medium to pass between the switching contact pieces.
  • non-conventional switching points are understood to mean a construction that varies the impedance behavior of the switching point independently of a mechanical movement. Regardless of the switching status of the switching point, a physical connection between the potentials to be separated is maintained. Only the impedance of the switching point is reversed.
  • the switching point can be formed, for example, by a semiconductor which, if necessary, is brought into an electrically conductive state or an electrically insulating state. Since the use of semiconducting components causes a current path to be switched through or interrupted by a semiconductor itself, these are also referred to as power semiconductors.
  • Non-conventional switching points are, for example, power electronics. In addition to the actual switching point, power electronics can also comprise further assemblies which serve to control the impedance of the switching point.
  • non-conventional Switching points can be used, for example, thyristors, GTO, IGCT, IGBT or general power transistors, etc. If necessary, the non-conventional switching point can also have a plurality of semiconductor elements and, if appropriate, be of modular construction.
  • a group of switching points forms an electrically conductive path which extends from a point A to a point B, each of the switching points being electrically connected in series.
  • the series connection of switching points is part of a switching path of the electrical switching device. This makes it possible for a voltage to be maintained between points A and B, which can be mastered during a switch-off process, to be distributed over a large number of switching points. In an ideal case, a voltage distribution across the switching points arises in such a way that approximately the same voltage drop occurs across each of the switching points and therefore each of the switching points can only be designed for a fraction of the total voltage to be controlled.
  • the switching device can have corresponding control means, such as control resistors, in order to achieve a voltage distribution that is as uniform as possible.
  • control means such as control resistors
  • the case is such that approximately one third of the electrical voltage to be controlled by the switching path of the switching device drops across each of the switching points.
  • a different voltage distribution is aimed at, depending on the design of the individual switching points, so that, for example, one of the switching points is loaded to a greater extent, whereby another switching point is relieved.
  • it is further possible to increase the number of conventional switching points but there is also the possibility of increasing the number of non-conventional switching points.
  • a further advantageous embodiment can provide that the non-conventional switching point is in the series connection between the first conventional switching point and the second conventional switching point.
  • An arrangement of the non-conventional switching point between a first and a second conventional switching point enables or supports a uniform distribution of the total voltage over the individual switching points.
  • the non-conventional switching point can be protected from overloads by conventional switching points located before and after it. For example, it is possible that in the conventional switching points an ignition of a switch-off arc in the course of an interruption of a current is desired, as a result of which a load at the non-conventional switching point is reduced due to the arcing voltage which arises and the increasing overall impedance in the series connection of the switching device.
  • Ignition of a switch-off arc is advantageous in at least one, in particular in the majority or all conventional switching points, in order to increase the impedance of the switching path of the switching device during a switch-off process and to interrupt the electrical current flowing via the switch-off arc / arcs support.
  • This makes it possible to reduce the dimensioning of the non-conventional switching point, so that it only has to interrupt a direct current that has already been reduced by the arcs. This results in a cost-effective, non-conventional switching point, which improves the overall cost situation for the switching device.
  • a further advantageous embodiment can provide that a large number of conventional switching points are connected in series and the non-conventional switching point divides the large number of conventional switching points into approximately the same groups of conventional switching points.
  • a large number of conventional switching points have at least a first and a second non-conventional switching point.
  • the conventional switching points are subdivided into a first and a second group.
  • Such a grouping of the conventional switching points supports the effectiveness of the non-conventional switching point.
  • the number of conventional switching points is increased to more than two switching points, the total voltage can be distributed over the switching points of the switching device accordingly and the voltage load on the individual switching point can be reduced.
  • the non-conventional switching point is protected against voltage overload by a voltage distribution through a large number of conventional switching points.
  • the groups should advantageously have identical impedances, so that there is a symmetrical voltage distribution between the groups.
  • the voltage load on the individual switching points is reduced, as a result of which the voltage distribution across the non-conventional switching point is also reduced.
  • a division into appropriate groups helps to compensate for asymmetries in the voltage distribution and thus to avoid overloading the individual switching points.
  • the same voltage load should advantageously be present in each of the groups in the event of a switch-off.
  • Such a symmetrical voltage distribution can additionally be supported by controlling the voltage distribution, for example by control resistors.
  • the number of conventional switching points should preferably be an even number, the same number of conventional switching points being arranged in the groups. However, it can also be provided that, depending on the design of the conventional switching points, different numbers of conventional switching points in the groups are included, so that, for example, the voltage distribution over the switching points can be controlled in an improved manner, in particular a uniform distribution of the voltage load over all switching points is achieved.
  • a further advantageous embodiment can provide that at least one of the conventional switching points has a vacuum switching chamber.
  • a vacuum interrupter delimits an evacuated space in which, for example, switching contact pieces that are movable relative to one another are arranged.
  • the individual switch contact pieces are separated from one another during a switch-off process, wherein a switch-off arc can be ignited between the switch contact pieces within the evacuated space.
  • the conventional switching points should be constructed in the same way so that a uniform distribution of the voltages to be controlled over the individual switching points can occur.
  • a rated voltage of 350,000 volts two groups of ten conventional switching points are used, a first group of ten conventional switching points connected in series before a non-conventional switching point and a second group of ten conventional switching points behind a non-conventional switching point are.
  • a rated voltage of 17,500 volts would result at each switching point.
  • voltage control should be assumed, so that the conventional switching points should, for example, be designed for a rated voltage of at least 20,000 volts.
  • the non-conventional Switching point also designed for 20,000 volts due to the series connection and arrangement between the two groups of conventional switching points.
  • the series connection of several conventional switching points in particular in front of and behind a non-conventional switching point, enables the use of power semiconductors with reduced rated voltages.
  • Another object of the invention is to provide a switch-off method for operating a switching device, the switching device having a first conventional and a second conventional switching point and a non-conventional switching point, the two conventional switching points and the non-conventional switching point being connected in series. According to the task, this is achieved in a switch-off method of the aforementioned type by first switching off the conventional switching points and then switching off the non-conventional switching point.
  • the switch-off method is particularly suitable for interrupting direct currents which are driven by a direct voltage.
  • all the conventional and the non-conventional switching point are in a switched-through state, ie the switching device to be switched off is in the switched-on state and has a current path of low impedance.
  • the conventional switching points are first interrupted, the non-conventional switching point still remaining in its ON state. Consequently, in particular when a direct current is interrupted, at least in one of the conventional switching points, but preferably in all conventional switching points, a switch-off arc is ignited between the respective switching contact pieces as a result of a contact separation. This can preferably take place within an evacuated room.
  • a recurring voltage is a voltage that, due to network impedances, oscillation processes or similar processes, sets over the switching path of the switching device during a switch-off process and can possibly reach a higher amount than the rated voltage of the switching device.
  • the non-conventional switching points are switched off.
  • the non-conventional switching point is blocked so that the non-conventional switching point interrupts the current to be interrupted and thus extinguishes the arcing faults that are burning in the individual conventional switching points.
  • the non-conventional switching point is blocked, the recurring voltage across the non-conventional switching point increases as a result of the interrupted electrical current.
  • the non-conventional switching point maintains the voltage at the switching device until the non-conventional switching points have a sufficient dielectric strength after the switch-off arcs have been extinguished in order to ensure electrical isolation on the switching device.
  • the non-conventional switching point only needs to master the electrical isolation on the electrical switching device in an initial interval of the increase in the recurring voltage. After a short recombination time If the conventional switching points are already open and the arcs have just gone out, the recurring voltage is distributed over the series connection of conventional switching points and non-conventional switching points.
  • the advantage of this switch-off method is that the non-conventional switching point only has to master the recurring voltage only during the recombination time of the conventional switching path. During this time, the recurring tension increases. The resulting voltage stress should be significantly lower than the respective rated voltage of the non-conventional switching point.
  • a further advantageous embodiment can provide that potential isolation is maintained by the non-conventional switching point until the conventional switching points are solidified.
  • the conventional switching points Due to the burning arc and the associated contamination, the conventional switching points require a finite time interval to solidify an insulating distance between the switching contact pieces. This improves the dielectric strength between the switching contact pieces of the conventional switching points within this time interval.
  • the conventional switching points can solidify, for example, within fractions of a second. During these fractions of a second, the non-conventional switching point is intended to control the dielectric strength of the switching device, in particular when a recurring voltage rises, and to prevent an arc from reigniting or an electric current from flowing again.
  • a further advantageous embodiment can provide that a burning arc in a conventional switching point is extinguished by the non-conventional switching point.
  • the switching path of the switching device is already prepared for a final interruption of the current during a switching process, in particular a switching-off process, on the switching device.
  • the burning arc already increases the impedance of the switching path of the switching device, whereby its impedance is not yet so great that a complete interruption of an electrical current takes place.
  • a complete interruption of the electrical current is caused by blocking the non-conventional switching path, so that an arc burning in the conventional switching point also goes out.
  • the conventional switching points receive a switch-off pulse almost simultaneously.
  • An almost simultaneous triggering of the conventional switching points causes an approximately synchronous movement of the switching contact pieces which can be moved relative to one another. Accordingly, an arc is advantageously ignited almost simultaneously in all conventional switching points, as a result of which an approximately simultaneous increase in the impedance of the switching path of the switching device is achieved.
  • Each arc is driven by a corresponding arc voltage, whereby the impedance of the burning arc can be estimated as higher than the impedance of the conventional switching points when switched on.
  • the circuit diagram according to Figure 1 shows a switching device 1, which serves to interrupt a current path between a point A and a point B.
  • the electrical switching device 1 is preferably designed for switching a direct current which is driven by a direct voltage.
  • the electrical switching device 1 has a first conventional switching point 2 and a second conventional switching point 3.
  • the switching device 1 has a non-conventional switching point 4.
  • the non-conventional switching point 4 is electrically in series between the first conventional switching point 2 and the second conventional one Switching point 3 arranged.
  • n first conventional switching points 2 and n second conventional switching points 3 are provided.
  • ten first conventional switching points 2 and ten second conventional switching points 3 can be provided.
  • the first conventional switching points 2 are all electrically connected in series, the first conventional switching points 2, which are on one side of the non-conventional switching point 4, forming a first group 5 of conventional switching points 2.
  • the second conventional switching points 3 form a second group 6 of conventional switching points 3.
  • the fact that the first and second groups 5, 6 of conventional switching points 2, 3 are connected in series to the non-conventional switching point 4 results in a series connection of conventional switching points 2, 3 and an intermediate non-conventional switching point 4.
  • the present non-conventional switching point 4 can in turn also have a modular structure and, for example, have a power semiconductor.
  • the non-conventional switching point 4 can have, for example, thyristors, IGBTs, power transistors, etc. based on semiconductors.
  • the Figure 2 shows a switching device 1a, which has a non-conventional switching point 4a, a first conventional switching point 2a and a second conventional switching point 3a.

  • the vacuum interrupters each have a tube body 9, which is fluid-tight and is evacuated inside.
  • the respective movable switch contact piece 8 projects through the respective tube body 9 in a fluid-tight manner and is relative to the tube body 9 and to the respective fixed switch contact piece 7 movable.
  • a drive device 10 is connected to the respective movable switching contact piece 8 and can couple a movement onto the movable contact piece 8.
  • the two fixed contact pieces 7 of the two conventional switching points 2a, 3a are each connected to a connection of the non-conventional switching point 4a.

  • the use of exactly one first conventional switching point 2a and exactly one second conventional switching point 3a is provided.
  • the arrangement of a non-conventional switching point 4a is provided between the two conventional switching points 2a, 3a.
  • further first or further second conventional switching points 2a, 3a can also be provided, which may be of identical construction, but may also have different designs.
  • the Figure 3 shows a diagram in which a graph 11 shows the time course of a direct current to be switched off.
  • a graph 12 symbolizes the dielectric strength of the conventional switching points 2a, 3a.
  • a graph 13 schematically shows the course of the recurring voltage after interruption of the direct current.
  • a graph 14 shows the course of the dielectric strength of the non-conventional switching point 4a.
  • a switch-off signal has already been sent to the conventional switching points 2a, 3a.
  • the conventional switching points 2a, 3a are already open.
  • the direct current to be interrupted initially continues to flow. Since the direct current is in the series circuit of the switching device 1a, arcs are ignited in the conventional switching points 2a, 3a.
  • the non-conventional switching point 4a is just in its switched-on state, ie the non-conventional switching point 4a has a low-impedance behavior.
  • the impedance of the switching device 1a is initially increased compared to its switched-on state.
  • the dielectric strength (graph 12) of the conventional switching point 2a, 3a is not yet given.
  • the conventional switching points 2a, 3a solidify during the time interval ⁇ t between the times t 1 and t 2 . After solidification, the dielectric strength of the conventional switching points 2a, 3a increases (graph 12).
  • the dielectric strength of the conventional switching points 2a, 3a also exceeds the dielectric strength of the non-conventional switching point 4a.
  • the dielectric strength of the non-conventional switching point 4a no longer needs to increase, ie the non-conventional switching point 4a can be designed such that with a further increasing voltage resistance of the conventional switching points 2a, 3a, the dielectric strength of the non-conventional switching point 4a no longer has to increase. Accordingly, there is the possibility of using inexpensive non-conventional switching points 4a.
  • An overlap in the time interval t 3 to t 4 and a further increasing dielectric strength of the non-conventional switching point 4a provide additional security in order to achieve a sufficient dielectric strength of the switching device 1a during a switch-off process.
  • a recurring voltage (graph 13) is applied to the electrical switching device 1a after an interruption of the direct electrical current.
  • a recurring voltage is established across the electrical switching device 1a.
  • this recurring voltage (graph 13) is not exclusively determined by the originally driving voltage, but transient processes can also occur during a switching process, which additionally increase the recurring voltage 13.
