Definitions

  • the invention relates to an on-load tap changer.
  • the on-load tap changer according to the invention comprises a switching tube, an energy store for setting a switching position of the switching tube, a detector for detecting a switching position of the on-load tap changer and an on-load tap changer gear.
  • the on-load tap-changer mechanism mechanically couples the energy accumulator to the switching tube.
  • On-load tap-changers (abbreviated as OLTC) are well known and common in the prior art. They are used for the uninterrupted switchover between different winding taps of step transformers. On-load tap-changers are divided into load selector and diverter switch with selector.
  • Both types of on-load tap-changers are actuated by a motor drive (preferably an electric motor) when switching over.
  • the motor drive moves an output or input shaft, which winds up a drive element of the on-load tap changer.
  • This drive element causes, for example, the movement of a switching tube of the on-load tap changer and is usually referred to as an energy store (or also an energy store).
  • an energy store or also an energy store.
  • the switch contacts serve for the direct connection of the respective winding tapping with the load derivation, the resistance contacts for the short-term connection, ie bridging by means of one or more switching resistors.
  • Vacuum interrupters are advantageously used as switching elements for load switching. This is due to the fact that the use of vacuum interrupters for load switching prevents arcing in the oil and thus prevents oil contamination of the diverter switch oil, as is the case, for example, in the German patents DE 195 10 809 C1 and DE 40 11 019 C1 as well as the German published documents DE 42 31 353 A1 and DE 10 2007 004 530 A1 described.
  • the international patent application WO 98/38661 A1 discloses a motor drive for tap changers, diverters or plunger coils.
  • the motor drive is used in particular to set the tap changer to the desired switching position. All the mechanical and electrical assemblies required to drive the tap changer are combined in the motor drive.
  • a step switch of the type of the reactor switch is described based thereon.
  • This also includes a motor drive with a downstream gearbox, in particular a Geneva gear or lever-type gearbox.
  • the Chinese utility model CN 201242930Y discloses an on-load tap-changer head for an on-load tap-changer for uninterrupted switching between different on-load tap positions.
  • the on-load tap-changer head includes an on-load tap-changer gear and a mechanical on-load tap position indicator.
  • an indicator shaft of the on-load position indicator connects directly to a gear shaft of the on-load tap-changer gear.
  • the on-load tap-changer head has a cover with a window through which the on-load position indicator can be read.
  • end position mechanisms are provided so that the on-load tap changer cannot be connected via a start or end position.
  • the Chinese utility model CN 201167023Y discloses an on-load tap-changer transmission with a display mechanism for switching position indication of an on-load tap-changer.
  • On-load tap-changer gear has a gear shaft to which a motor driving the switching tube of the on-load tap-changer can be coupled.
  • the gear shaft drives an input shaft of the on-load tap-changer gear via a worm gear.
  • a coupling element is formed on the underside of an end of the input shaft facing away from the motor, via which the input shaft is coupled to the switching tube of the on-load tap changer.
  • one end of the indicator shaft protrudes from the housing of the on-load tap-changer and is provided with a pointer which can be rotated against an indicator disc with switching position marks.
  • the pointer can be optically enlarged for better readability.
  • a disadvantage of the on-load tap-changer gear with a display mechanism of the Chinese utility model CN 201167023Y is that the display mechanism picks up the movement of the input shaft to pull up an energy accumulator.
  • the tap on the input shaft is prone to errors because any slip that may occur between the input shaft and the energy accumulator is not detected, so that the indication of the switching position is inaccurate.
  • a position reporting arrangement for a motor drive is known.
  • This motor drive and thus also the position indicator arrangement are arranged on the outside of the high-voltage transformer and are connected to a tap changer, diverter or plunger coil, for example, via a linkage.
  • the position reporting arrangement is used for remote position display or position information.
  • the energy accumulator has a support plate on which a gear wheel and a drive element are arranged.
  • the drive crank is actuated via the two stops of the drive element.
  • a pull rod and several compression springs are attached to the drive crank.
  • the drive element is turned, the compression springs are tensioned and the energy accumulator is opened.
  • the rotary movement of the drive element is transmitted to the selector shaft and thus to the Geneva wheel.
  • Another one Role the rotary movement of the drive element is transmitted to a Geneva wheel, which is connected to a position indicator.
  • DE 100 62 679 A1 discloses an on-load tap-changer comprising a switching tube, an on-load tap-changer gear, an energy store for setting a switching position of the switching tube, a detector for detecting the switching position of the on-load tap-changer, the detector being mechanically coupled to the energy accumulator via the on-load tap-changer transmission and an electronic signal for detecting the by means of the detector Switch position of the on-load tap changer can be output.
  • the object of the invention is to provide an on-load tap-changer, the switching positions of the on-load tap-changer being able to be detected reliably, tamper-proof and in a manner not prone to errors.
  • the on-load tap-changer should also be easy to maintain.
  • the invention relates to an on-load tap changer.
  • the on-load tap changer according to the invention comprises a switching tube and an energy accumulator for setting a switching position of the switching tube.
  • the on-load tap-changer comprises a detector for detecting a switching position of the tap-changer and an on-load tap-changer gear. Both the switching tube and the detector are mechanically coupled to the energy accumulator via the on-load tap-changer gear.
  • a preselector and possibly a fine selector of the on-load tap-changer are each mechanically coupled via the on-load tap-changer transmission to the energy accumulator for setting a switching position of the preselector with the detector for detecting its switching position.
  • the switching position of the on-load tap-changer results from a combination of the position of the switching tube, preselector and, if necessary, fine selector.
  • the on-load tap-changer transmission for example, couples a superposition of the movements of the switching tube, preselector and possibly fine selector into the detector.
  • the detector can detect a mechanical input signal that is coupled in via the on-load tap-changer transmission and convert it into an electronic signal of the switching position of the on-load tap-changer and output it.
  • an electronic circuit board can be provided in the detector, which processes the electronic signal further, for example, amplifies and / or digitizes it.
  • the detector can comprise a cam switching mechanism and / or an encoder system.
  • the detector comprises a cam switching mechanism which consists of at least one cam disk with a plurality of switching position positions and at least one cam.
  • the at least one cam can be releasably connected at each switch position.
  • the cam disk of the detector is used, for example, to detect the end position of the on-load tap-changer. In particular, incorrect switching of the on-load tap-changer can be avoided.
  • the at least one cam disk can each be assigned at least one switch for detecting an end position of the on-load tap changer such that each switch can be actuated with at least one cam.
  • the actual detection of the switching position of the on-load tap-changer can be done via an encoder system take place, which is partially integrated on the cam disc.
  • the sensor system can be designed, for example, as a Hall effect sensor, optical sensor or potentiometer.
  • it comprises several sliding contacts and one grinder. At each switching position of the at least one cam disk, at least one sliding contact is formed, which can be electrically coupled to a slider.
  • a cam disk according to the invention is sufficient to completely record the end positions and switching positions of the on-load tap-changer.
  • the detector can be designed redundantly with several such cam disks.
  • a grinder can simultaneously electrically couple the sliding contacts of two cam discs.
  • the detector can be adapted to on-load tap changers with different numbers of switching positions by simply moving cams on the cam disc.
  • the modular components of the detector can be standardized. This lowers the cost of producing and maintaining spare parts.
  • a detector housing for receiving the detector can be arranged on a cover of the on-load tap changer.
  • a housing cover can be detachably attached, so that the detector can be easily serviced or replaced without having to dismantle the on-load tap-changer cover or remove the on-load tap-changer gear.
  • a running detector In addition to the detector for detecting the switching position of the on-load tap changer, a running detector can be provided.
  • the running detector is assigned to an input shaft of the on-load tap-changer transmission, via which the energy accumulator can be pulled up.
  • the running detector can detect the rotary motion of the input shaft and convert and output it as an electronic signal. If necessary, the input shaft couples to an electric motor or to a manual emergency operating means via a motor gear. The detection of their rotary movement makes it possible to monitor how the energy store is pulled up via the electric motor or the emergency actuation means.
  • the running detector can be designed as an encoder system, for example as a cam switch mechanism.
  • the encoder system can be designed as an absolute encoder. Absolute encoders output length or angle information of a device to be measured in the form of an absolute, usually digitized, numerical value. Since no reference to a reference is necessary, they can start measuring operation immediately after switching on, which is advantageous for the simple and safe operation of the on-load tap-changer according to the invention.
  • the detector or the detector and the running detector are electrically connected to a control unit for controlling or regulating the on-load tap changer.
  • the electric motor of the on-load tap-changer can be operated on the basis of the electrical signals from the detector and possibly the running detector be regulated, which ultimately drives the on-load tap-changer.
  • the inventive idea which is implemented in the on-load tap-changer, is based on tapping the abrupt drive movement of the energy accumulator, which actually acts on the switching tube and possibly the selector, instead of a continuous movement of the input shaft, which pulls the energy accumulator on and not with the switching tube in Active connection is established. If the lift mechanism e.g. if it is jammed or is not fully opened by mistake, so that it does not trip, then the switching position displayed would fall apart from the actual switching position in an on-load tap changer of the prior art. So far, the detection of the switch position has been based on the rotary movement of the input shaft. The input shaft and the energy accumulator can move independently of each other.
  • the rotary converter of the on-load tap-changer transmission has a driver and a cam driver for coupling a movement of the energy accumulator onto the detector and onto the switching tube.
  • Driver and cam driver are rigidly coupled to each other. This ensures that the energy accumulator always acts on the detector and switching tube at the same time.
  • the movement of the energy accumulator is transmitted to the detector and the switching tube by a mechanical transmission mechanism of the on-load tap-changer transmission.
  • the components of these transmission mechanisms can be stable, compact and slip-free. They are also located inside the on-load tap-changer, protected from environmental influences. As a result, the entire on-load tap-changer transmission is exposed to the same temperature range, so that thermally induced mechanical play or tension is avoided.
  • a major advantage of the invention lies above all in the simple coupling of the detector integrated in the on-load tap-changer gearbox for detecting the switching position of the on-load tap-changer.
  • Existing state-of-the-art solutions emulate the on-load tap-changer gearbox in the motor gearbox of the electric motor coupled to it.
  • the associated coupling process and the synchronization of the electric motor and the on-load tap-changer becomes very complex and prone to errors. If the displayed and actual switching position differ, an erroneous coupling and switching process can lead to the end position limits being broken. This is excluded according to the invention.
  • the simplification according to the invention replaces a control gear necessary for this coupling process.
  • Another advantage of the invention is that the electric motor is expanded, for example, for normal maintenance work can be done without having to intervene in the mechanical coupling between the detector of the on-load tap-changer transmission and the switching tube. As a result, the displayed and the actual switching position of the tap changer cannot differ. When installing the electric motor, no complex recalibration of the displayed and actual switching position is necessary.

  • the load selector 1 here has an electric motor 3 with a gear 5 as a drive, which pulls up an energy store (not shown).
  • an energy store not shown.
  • the rotating switching tube 15 is rotatably arranged in the oil vessel 18 so that different switching positions can be set.
  • the oil vessel 18 is closed at the top with a lid 19 and also carries a bottom 21.

  • the preselection driver 140 couples the switching movement of the preselector 37 to rotary transducer 130, which likewise acts on the detector 200 via the display driver 150.
  • This effect can consist, for example, in that the direction of rotation of the twentieth rotation caused by the switching tube 15 is reversed in the detector 200.
  • the switching movements of the switching tube 15 and the preselector 37 can be simultaneously coupled into the detector 200 and detected via the on-load tap-changer transmission 100.
  • Both the position of the switching tube 15 and the preselector 37 go into the switch position of the on-load tap changer 1 which can be detected in this way. If, for example, the switching tube 15 has 8 switching positions and the zero position and the preselector 37 have a “plus position” and a “minus position”, a total of 19 results for the on-load tap changer 1 Switch positions that can be represented on the detector 200, for example, as "-8, ..., -1, 0, +1, ..., +8". For example, the switching position "-3" means that the preselector 37 is in the "minus position” and the switching tube is in the third of eight switching positions. Analogous to the preselector 37, a fine selector (not shown) can also be integrated into the switching position detection via the on-load tap-changer transmission 100.
