Definitions
- the invention relates to a drive unit for a tap changer for actuating switch contacts.
- motor drives are usually used to operate on-load tap-changers. Despite the interaction of motor drive and
- Tap changers are arranged spatially separated.
- the on-load tap-changer itself is recessed into the transformer tank, with the exception of the top-standing tap-changer head, while the motor drive is outside the transformer, usually at the transformer
- Tap changer known by a motor drive.
- the outside of the transformer housing arranged motor drive actuates the tap changer via drive shafts.
- the motor drive is controlled by means of a voltage regulator, which determines the control commands by constantly comparing the actual and nominal voltages on the transformer.
- Vacuum interrupter known.
- a switching contact of a vacuum interrupter is connected to the protruding end with a movable core.
- Direction of movement of the core corresponds to the opening or Schüeßschisplatz the switching contact of the vacuum interrupter.
- the core moves when closing or opening between two end positions, on each of which a current-acting coil is arranged. By selectively applying voltage to one of the coils, a force is induced, the core moves and the vacuum interrupter is opened or closed.
- a major disadvantage of the known from the prior art drive units is the load and control gears used. The connection of these individual gears with each other is complex and time consuming and costly.
- the use of simple three-phase motors as drive means brings disadvantages. So it is very difficult and costly especially to obtain three-phase motors with constant laseck loved.
- the inhomogeneity of the parameters of the three-phase motors requires additional sensors or customized gearboxes.
- the wave trains are also a major source of error
- the couplings used to interconnect the shafts wear out over time and can not guarantee a safe and reliable operation. Little play of the individual parts adds up over the entire drive train and forms at the end, namely on the tap changer, large deviations.
- the object of the invention is therefore to provide a drive unit for a tap changer, which is arranged closer to the tap changer, ensures a fast and safe operation of the tap changer and is constructed compact.
- the object is achieved by a drive unit for tap changer according to the features of the first patent claim.
- the respective subclaims relate to further advantageous developments of the invention.
- a drive unit for tap changer which consists of a solenoid arranged directly on the switching contact, which opens or closes the switching contact by applying a voltage.
- Fig. 1 is a drive unit for a tap changer
- Fig. 2 shows an embodiment of the drive unit with two coils
- Fig. 4 shows a special interconnection of drive units
- Fig. 5 is a drive unit with a coupling element
- FIG. 6 shows a drive unit with an indirect actuation of a switching contact via a link
- Fig. 7 shows a drive unit with an indirect actuation of a switching contact via a rack and a cam
- a drive unit (1) for a tap changer with a housing (2), a coil (3) and an armature (4) is shown.
- the coil (3) is fixedly mounted in the housing (2) and is electrically connected to a voltage source, not shown here.
- the armature (4) is arranged in the housing (2) such that it is at least partially enclosed by the coil (3).
- the armature (4) is designed as a magnet and has a north and a south pole.
- the armature (4) preferably consists of a hard to
- demagnetizing material e.g. a samarium-cobalt alloy or a neodymium-iron-boron alloy.
- the armature (4) is in addition at one end via a connecting piece (5) with a
- Switch contact (6) closed or opened.
- the switching contact (6) may e.g. be realized by a vacuum interrupter, a mechanical contact or the like.
- the actuation of a plurality of switching contacts (6) by means of a drive unit (1) is possible.
- Switching contacts (6) can be adjusted.
- Direction of movement of the armature (4) depends on the direction of the current flow and is linear along an axis of symmetry (7).
- the movement of the armature (4) thus leads to an opening or closing of the switching contact (6) and is thus dependent on the flow direction of the electric current.
- Fig. 2 shows a possible embodiment of the drive unit (1) for tap changer, in which the armature (4) at least partially enclosing the first coil (3) is not fixed in the housing (2), but at least from a second coil (8) partially enclosed.
- the coils (3, 8) are mechanically interconnected.
- the first coil (3) can thereby be used as an anchor and also perform a linear movement along the axis of symmetry (7). This is necessary above all when the force generated by the first coil (3) is insufficient to open the switching contact (6).
- FIG. 3 shows a further embodiment of the invention, in which a first drive unit (1.1) is arranged behind a second drive unit (1.2) and both have a switching contact (6) press.
- Both drive units (1.1, 1 .2) have different characteristic values with regard to the lifting height and / or the lifting force, but function according to the same principle as the drive unit (1) from FIG. 1.
- different phases of an opening or closing operation can be achieved Closing operation can be controlled.
- Fig. 4 a further Verschaltungsschkeit the drive unit (1) is shown.
- Each switching contact (6a, 6b, 6c, 6d) is connected to a separate drive unit (1 a, 1 b, 1 c, 1 d).
- drive units (1 a, 1 b, 1 c, 1 d) are connected to a further, significantly larger drive unit (9).
- the drive unit (9) should be used primarily as a support and come eg in welded switch contacts used; So as a kind of security element.
- a coupling element (10) between the drive unit (1) and the switching contact (6) is arranged. This works according to the impact principle and is especially for loosening glued or welded
- Switching contacts (6) suitable.
- the drive unit (1) via a coupling ram (1 1), the coupling (10) and via the connecting piece (5) with the switching contact (6) is mechanically connected.
- the movement is transmitted to the coupling ram (1 1). Since this has a freewheel, it is initially not to actuate the switching contact (6).
- a pulse is generated by the suddenly occurring resistance via the coupling (10). This is transmitted to the switching contact (6) and dissolves the welded and glued points in the switching contact (6).
- the pulse strength can be varied.
- Fig. 6 shows a further embodiment of the invention.
- drive unit (1) and switching contact (6) indirectly indirectly via a link (12) in conjunction.
- Connecting piece (5) has at the upper end a cam (13) which scans the contour of the link (12) and thus actuates the switching contact (6).
- the link (12) is also mechanically connected via a connecting element (14) with the drive unit (1). By actuating the drive unit (1), the link (12) is moved via the connecting element (14). About the contour of the slide (12) and the cam (13) of the switching contact (6) through the connecting piece (5) is actuated.
- FIG. 7 shows a further embodiment in which the drive unit (1) actuates a toothed rack (15). This is mechanically connected to a gear (16) and thus converts the linear movement of the rack (15) into a rotational movement.
- the Gear (16) is also connected to a cam (17) which actuates by rotation the switching contact (6) via the connecting piece (5).
- a particular advantage of the invention is that the individual drives independently of each other actu bar and thereby complex switching operations can be realized. Also positive is the omission of the many gears and the waves. The simplified design and the no longer required items simplify production and reduce costs. The effects of wear on individual parts also lose their importance due to the reduction of the drive unit to just a few components. The replacement of defective or worn components can be faster and more targeted.
- the drive unit can be made particularly compact, since only one coil is needed and the direction of movement of the armature depends on the polarity of the applied voltage.
- the control of the polarity of the voltage can be realized very easily and inexpensively. Since the anchor consists of a special, difficult to demagnetize material or alloy, this retains its ferromagnetic property even at high temperatures. This enlarges the field of application of the invention.
