Definitions

  • the invention relates to a drive for the movable contact piece of an electrical switching device, for. B. a high-voltage circuit breaker, in particular an SF 6 circuit breaker, a load break switch or the like.
  • Such drives can hydraulically move, particularly in circuit breakers Press the contact piece.
  • an energy store is provided that after a shutdown sequence in which he discharged at least for the most part will be excited again.
  • the energy store can be used as a gas spring energy store be formed, which is divided by a movable partition, wherein compressible gas on one side of the partition and on the other side the intermediate wall hydraulic fluid is present.
  • the gas is compressed by means of pumped hydraulic fluids; with a shutdown sequence the gas relaxes and drives the hydraulic fluid into a corresponding one Piston-cylinder arrangement with which the movable contact piece is actuated.
  • a mechanical spring accumulator can also be used are, the spring arrangement tensioned in the same way as the gas, d. H. pressed together becomes; in the event of a switch-off action, the spring energy is applied to the hydraulic fluid transmitted, whereby the piston-cylinder arrangement is actuated again.
  • Disconnector e.g. B. switch disconnectors, in which a circuit under load must be operated mostly by means of a spring-loaded arrangement.
  • electric motors can also be used, since these are mostly only a rotating drive, at least slower than a circuit breaker with a lower force density.
  • a magnetic drive has recently been developed in which a closed Yoke is provided in which an anchor can move; this magnetic drive, however is mainly for vacuum interrupters because of the low armature stroke intended.
  • the object of the invention is to provide a drive of the type mentioned in the introduction, in which, with optimal control, the structure is simple, the wear and the maintenance are low and for which special monitoring devices such as those at hydraulic drives are required can be avoided.
  • This object is achieved in that the fixed part cylindrical tube, on the inside of which coils for generating a magnetic Are arranged moving field, is formed, whereas the movable part as inside of the tube movably sliding anchor is formed by the traveling field is driven.
  • a first embodiment of the invention can be that the anchor, that is the movable part has at least one permanent magnet, the north and South poles are aligned axially.
  • Ring magnets must be arranged so that the poles of the same name face each other.
  • An iron ring can be arranged between two permanent magnets.
  • the anchor has at least two permanent magnets, whose north and south poles alternate radially outwards and are directed inwards.
  • the anchor can also have a guide rod here, on which the permanent magnets are lined up in disk form.
  • the permanent magnets are arranged at such a distance from one another, that a desired magnetic induction curve, e.g. B. a sinusoidal Course along the axis is achieved.
  • the permanent magnets are plastic-bonded and have a low flux density have, they can be used in particular for switch disconnectors or disconnectors become.
  • the iron sections lead with introduced Movement to changes in inductance within the stator coils, for position detection can be used.
  • the invention is particularly simplified in that both the stator as well as the anchor, that is to say the movable part, composed of segments could be.
  • a different one is used to achieve different force densities Number of segments for the movable part mechanically arranged one behind the other; in the same way, to achieve different travels, that is Drive strokes, a different number of stator segments mechanically one behind the other be arranged.
  • the segment length is s and the achievable force with a segment for the moving part is designated K1
  • the entire Anchors have a length of n x s and the stator of m x s, where n and m are different Mean segment numbers; the number of segments in the stator would be greater than that at anchor.
  • the total travel distance is then (m - n) x s and the force density n x K1.
  • the arrangement with permanent magnets works accordingly on the synchronous principle, where a high power yield when using the disc-shaped permanent magnets and when using plastic-bonded permanent magnets lower flux density an average power yield is achieved.
  • the anchor acts as an anchor rod is designed and serves as a short-circuit cage
  • the power yield is comparatively low and the so-called rise time longer, so that such a drive construction for Disconnector and / or earth switch drives can be used.
  • the particular advantage of the configuration according to the invention is that a Uniform fixed part, i.e. a uniform stator for all switching tasks can be used; the adaptation to the respective switching device and the respective Switching task is achieved by suitable design of the moving part.
  • the inside part is the fixed part whereas the tubular outer part is movable; the inside can fixed part also carry the coils; however, there is a cheaper solution in that the coils are arranged on the inside of the tubular part.
  • the drive 10 shown in FIG. 1 for a shown only schematically Circuit breaker 11 has a fixed part 12 in the form of a cylindrical tube, in which grooves 13, 14, 15 and 13a, 14a and 15a are introduced, in which Coils 16, 17 and 18 are located, the coil sections with 16a, 16b, 17a, 17b and 18a, 18b are designated.

  • a movable part 20 Within the cylindrical tube is a movable part 20, the one has rod-shaped core 21 made of soft iron, on which two permanent magnets 22nd and 23 are arranged which are at a distance D from one another. Within the through the distance D a soft iron disc 24 is arranged.
  • FIG. 3 shows such an embodiment.
  • the two disc-shaped permanent magnets 22 and 23 are assigned to one another such that the permanent magnet 22 with its south pole to the core 21 and the permanent magnet 23 with its north pole to Core 21 are directed (Fig. 1).
  • the iron disc 24 the axial thickness of which is small compared to the axial thickness of the Permanent magnets, essentially causes a kind of asymmetry with the position positions of the armature 20 can be detected.
  • FIG. 1 A total of six pills for taking up the coils are shown in FIG. 1; Of course more pills can be arranged; in the same way the anchor 20 wear more than two permanent magnets.
  • This configuration is a three phase Arrangement of the coils, which is preferred because a for controlling A large number of control components are readily available commercially and are known.
  • FIG. 2 now shows a perspective view of the fixed part 12 in shape a cylindrical tube.
  • the closed field lines with the reference number 30 are designated; these field lines run from the fixed part into the Permanent magnets, back through the core 21 through the permanent magnets the fixed part 12.
  • the permanent magnets 22 and 23 can be designed as conventional permanent magnets with a high flux density, then a drive force F (see FIG. 1) can be generated with a fixed part of the same design, which is expedient for circuit breaker drives, in particular SF 6 switch drives. If the permanent magnets are plastic-bonded and have a lower flux density, then such drives can be used to drive load switches and disconnectors.
  • FIG. 5 shows another embodiment of the invention. It has a stator 50, which is cylindrically hollow, on the inner surface of which grooves 51, 52, 53 and 54, 55 and 56 Vietnamese are introduced. In the grooves 51 to 53 there are coils 57, 58 and 59, in which the current in the arrangement shown in FIG. 5 in the drawing plane flows into it.
  • These coils are circular and assigned to the individual phases R, S and T, where coil 57 of phase R, coil 58 of phase S and coil 59 of Phase T is assigned.
  • the coil 60 is the phase R
  • the coil 61 is the phase S

  • the magnetic lines run as in Fig. 5:
  • the flux lines 72 generated by the permanent magnet 67 run in the permanent magnet from the south pole to the north pole, from there through the iron disk 69 and through the air gap 73 into the stator, in the stator back to the iron part 70 and back into the south pole of permanent magnet 67.
  • the field lines 74 generated by the permanent magnet 68 are reversed through the permanent magnet 68.
  • the field lines 72 run in the drawn position and representation counterclockwise and the field lines 74 clockwise.
  • a traveling field is generated, which is the anchor 65, that is to say the movable part 65 drives in the direction of arrow F, thereby making a movable Contact piece can be driven.
