Definitions

  • the invention relates to a tap changer for uninterrupted switching between different winding taps of a control transformer.
  • Tap changers have been known devices for voltage regulation and ensuring a high quality of electrical energy for decades. Their basic mode of operation allows them to be subdivided into resistance quick switches and reactor switches.
  • this on-load tap-changer is carried out by a motor drive with an electric motor, which, when put into operation, puts it on the one hand the fine selector and possibly a preselector continuously
  • the motor drive sits laterally outside of the transformer, and the linkage, angle drive, gear stages and mechanical Geneva gearbox turn the energy into a tap-changer Itet. Has the energy storage reaches its end position, d. H. when fully raised, its hitherto fixed detent is released, and it makes a sudden movement with which it actuates the diverter switch.
  • the drive trains of this known on-load tap-changer are shown schematically.
  • a modified such on-load tap-changer is shown, which has a multiple coarse selector instead of a conventional preselector; this arrangement is also known to the person skilled in the art.
  • a tap changer of the type of reactor switch is z. B. from DE-PS 40 11 019 and DE-PS 41 26 824 and the company publication "Load Tap Changer Type RMV-I" of Reinhausen Manufacturing Inc., Alamo, Tennessee, USA known. They have two load branches preselectable by a tap selector, between which a switch, in this case a vacuum switch cell, is arranged in each phase to be switched. Each vacuum switching cell can be bridged by a bypass contact, which in turn connects at least one of the two load branches to the load discharge. The actuation of the vacuum switching cells is carried out by a respective energy storage, which is wound up by the movement of a drive shaft.
  • a double-sided cam is spatially arranged between the bypass contact and the energy storage, which is rotated by the drive shaft at each switching step by 180 degrees.
  • On the side facing the bypass contact side of the double-sided cam there is a groove for controlling the bypass contact and on the other side another groove for controlling the vacuum switching cells driving force accumulator.
  • the control of the force accumulator is such that it is tensioned once each switching step and then triggered and thereby actuates the vacuum switching cells.
  • the operation of this tap changer is done by a motor drive with an electric motor, which, it is set at an intended switching in operation, on the one hand, the selector contacts continuously actuated and on the other hand via the cam described both the bypass contact also continuously actuated and raises the described energy storage. Has the energy storage reaches its end position, d. H. when fully raised, its hitherto fixed detent is released, and it makes a sudden movement with which it actuates the diverter switch.
  • the drive trains of this known tap changer are shown schematically.
  • the drive is effected by an electric motor drive.
  • a drive is described for example in WO 98/38661.
  • Important mechanical assemblies are the load gear and the control gear.
  • the load gearbox directly actuates the tap changer; It has a correspondingly dimensioned electric motor.
  • the control gear includes a cam which rotates one full turn each time the tap changer is changed over.
  • the cam disk in turn has a plurality of switching cams for the mechanical actuation of numerous cam switches or cam-actuated contacts.
  • the control gear further includes means for displaying the tap position or the switching step.
  • the electrical components in the motor drive include different circuits.
  • a motor circuit through which the terminals of the electric drive motor via motor contactors, brake contactors and other switching means are connected to the power supply line. Furthermore, a control circuit and various signaling circuits and trip circuits for a motor protection switch are available.
  • the control of the motor drive itself takes place according to the principle of stepping, d. H. an adjustment by a switching step is initiated by a one-time control pulse and then inevitably completed; the output shaft of the motor drive, which is coupled to a drive shaft of the tap changer, doing so in advance a precisely defined number of revolutions.
  • the known motor drive in addition to other safety devices, also a continuous protection device, which prevents the failure of the described step control of the motor drive passes through to the end position.
  • the object of the invention is to simplify the basic structure of tap changers, as it has been established for decades and solidified in the prior art, drastically.
  • the invention is based on the general inventive idea of using at least one known per se torque motor as part of the drive train or strand of a tap changer.
  • Such torque motors are known, for example, from the company publication "Brushless Torque Motors” from ETEL. Such a known torque motor works on the same physical basis as a linear drive, except that the here lying flat stator is wound into a circle. A torque motor is therefore a high torque optimized servo drive; Modern versions are 3-phase brushless synchronous motors with permanent excitation. They are currently used in the machine tool industry. It has not yet been attempted to implement them in tap changer or to make it usable in principle for the drive of a tap changer.
  • EP 996 135 relates to a magnetic traveling-field drive for a switching device
  • WO 99/60591 and WO 00/05735 describe drives in the manner of a stepping motor for switching devices.
  • such a torque motor can be provided as part of a tap changer at different locations. It can be arranged outside the transformer room, on top of the transformer or on the side of the transformer. It can also be arranged within the transformer room and there replace the power storage of the diverter switch, the fine-vote drive or a preselector drive or even more of these modules.
