Definitions

  • the invention relates to an on-load tap-changer.
  • On-load tap-changers and Lasi duplexier are used to transform the transformers
  • Winding taps of these transformers switch under load and thus
  • On-load tap-changers as known from the published patent application DE10055406C1, usually consist of a selector for power-free preselection of those
  • Winding taps of the transformer to be switched to, as well as a diverter switch for the actual uninterrupted switching from the previously connected winding tap to the new, preselected winding tap.
  • a contact path leads via a closed contact the current, while on the second contact path, the next winding tapping is preselected to carry the current after the load switching.
  • the actual load switching takes place with the aid of vacuum interrupters or mechanical contacts. Due to the oil contamination arising during switching, the vacuum interrupters or the mechanical contacts with the associated mechanical components are accommodated in a separate oil cylinder.
  • the selector is due to the type either in the transformer housing or in a separate oil cylinder.
  • a disadvantage of the on-load tap-changer is that they consist of many components. As a result, the assembly and maintenance are very time-consuming and thus expensive.
  • Load selectors consist inter alia of an oil tank cylinder. This is made of an insulating material and has a radially arranged, three-part cam track inside. Below the cam track are three externally arranged power terminals, which are connected to a slip ring located inside. Above the cam track are the step contacts, which are connected to the respective taps of the stepped windings and engage in the interior of the cylinder. Through the interior of the oil cylinder cylinder extending from an insulating material switching shaft extends. At this, two, over a base plate and a partial cylinder horizontally mounted vacuum interrupters mounted in a contact carrier, sliding contacts with guide arms and numerous other parts. By the rotation of the rotation of the oil tank cylinder. This is made of an insulating material and has a radially arranged, three-part cam track inside. Below the cam track are three externally arranged power terminals, which are connected to a slip ring located inside. Above the cam track are the step contacts, which are connected to the respective taps of the stepped windings
  • Vacuum interrupters set minimum requirements for the installation space and thus at the circumference of the oil cylinder. Due to the radial arrangement of the connections for the individual winding taps on the circumference of the oil cylinder and the given
  • Minimum distances of neighboring terminals is the division, i. the maximum number of connections at a certain extent, limited.
  • the object of the invention is to provide an on-load tap changer, which combines the advantages of an on-load tap changer and a load selector, while having a low plastic space and can be expanded in the simplest way to additional shadow contacts.
  • the subclaims relate to advantageous developments of the invention.
  • the invention is based on the general idea to fix fixed by cam actuated switching contacts (vacuum interrupters) and both the tap contacts, to switch from one winding tap to the next, and the contacts and Ableitessore, which are actuated by a screw vertically with each other, below the switch contacts, to arrange.
  • Fig. 1 an on-load tap changer according to the invention
  • Fig. 2 shows a possible switching sequence of an on-load tap changer according to the invention from a first tap contact to a second tap contact

  • Fig. 4 shows another embodiment of the contacts in Figure 1 is an inventive, three-phase on-load tap-changer 1 for
  • Stepped transformers shown.
  • a force accumulator 2 is arranged at the upper end of the on-load tap changer 1. This operates as trained as a screw spindle
  • a contact carrier 8 is mechanically connected to the drive shaft 3. Depending on the direction of rotation, the contact carrier 8 can move vertically upwards or downwards without rotating itself.
  • the contact carrier 8 consists of a sleeve member 9 and at least one contact arm 10.
  • the sleeve member 9 is inside
  • the sleeve member 9 serves as a connecting means between the drive shaft formed as a screw 3 and the contact carrier 8.
  • At one end of the contact arm 10 at least two galvanically separated contacts 11 and 12 are arranged. In the example shown, the contacts 1 1 and 12 are designed as sliding contact finger pairs.
  • each contact arm 10 at least two corresponding Ableitromee 13 and 14 are assigned vertically.
  • the Ableitcard 13 always has an electrically conductive and mechanically sliding connection to one end of the contact 11. Since it is in Beispie! is a contact finger pair, the diverter 13 slides in between. This also applies to the discharge contact 14 and the contact 12th
  • the contact arm 10 via a recess 15, in the form of a bore with one of the Ableitessore, here Ableitcard 13, mechanically connected.
  • the discharge contact 13 also has the function of a guide for the contact carrier 8 and prevents it from rotating with the drive shaft 3.
  • each contact arm 10 is assigned an insulating rod 16 made of an electrically non-conductive material.
  • Isollerstab 16 corresponding to the contacts 11 and 12 electrically conductive step contacts 17 are arranged linearly along a vertically extending path. These are mutually offset and extend from the inside of Isoiferstabes 16 to the outsides. On the outside of the insulating rod 16, the different are at the stage contacts 17

  • the sleeve member 9 of the contact carrier is moved linearly down or up to the next stage contact 17.
  • the contact 1 1 of the tap contact 17 dissolves.
  • the vacuum sight tube 6 is opened via a deflection arrangement 5 with the aid of a cam disc 4, which is likewise driven by the drive shaft 3 (diagram C).
  • the contact carrier 8 has covered such a way that contact 11 is applied to a next stage contact 17 (diagram D), up to this point, the current through contact 12 and
  • Vakuumschaitube 7 flowed to the discharge 18.
  • the vacuum sight tube 8 is closed. This creates the so-called, circular current (diagram E).
  • Another cam 4 then opens the vacuum sheath tube 7 (diagram F), so that the windings of the adjacent stage contact 17 can be tapped.
  • the contact carrier 8 has moved so far that the contact 12 rests against the step contact 17.
  • the contacts 1 1 and 12 have reached their end position and one of the cams 4 closes the vacuum sheath tube 7, so that the current can flow through this to the derivative 19.
  • the compact design has fewer components compared to on-load tap changers of the prior art.
  • On-demand tap-changer 1 can be easily extended downwards if required and can easily be extended by additional contacts for further control windings.
  • the extension to further developments is much easier to implement than with conventional ones
  • FIG. 4 shows an alternative form of the contacts 11 and 12. These are not designed as sliding contacts, but have at the ends conductive Rolfen 20, in the up and down movement can be reduced by the rolling wear of the contacts 11 and 12.

Abstract

L'invention concerne un changeur de prises en charge, constitué d'un accumulateur d'énergie, d'un arbre d'entraînement réalisé comme une broche à vis, d'ampoules à vide et d'un porte-contacts et de contacts étagés disposés verticalement. L'actionnement des ampoules à vide s'effectue en fonction des contacts. Les ampoules à vide sont actionnées par des disques à cames et des ensembles de renvoi. Parallèlement à cela, les contacts montés sur le porte-contacts sont déplacés verticalement par l'arbre d'entraînement, les contacts étagés étant ainsi commutés.
