Definitions

  • the invention relates to a tap changer for uninterrupted switching between winding taps of a tapped transformer with a Olausdehnungsgefäß.
  • a tap changer which has a separate Olausdehnungsgefäß, which is located directly above the head of the tap changer.
  • This Olausdehnungsgefäß lies within the contour of the tap changer head.
  • the Olausdehnungsgefäß is designed as a separate vessel and connected via a pipe socket with the head of the tap changer and thus the oil volume.
  • Transformer boiler is sunk, be provided.
  • the oil flow line to the Olausdehnungsgefäß must be adapted in each individual case to the specific spatial relationships between tap changer head and Olausdehnungsgefäß. Although this latter adaptation is omitted in the well-known from DE 35 04 916 A1 design of ⁇ lausdehnungsgefäßes directly above the tap changer head, but there are corresponding flanges and a connecting pipe socket required.
  • Compensating device is mounted directly on the tap changer head. In this case
  • the object of the invention is to provide an oil-filled tap changer, which has a simple and inexpensive way means for oil expansion, without a spatially remote or otherwise independent Olausdehnungsgefäß is required. It is another object of the invention to provide an oil-filled tap changer, which allows mounting, dismantling and opening the lid, without previously a separate
  • the general inventive idea is to provide an oil conservator, open at the top and bottom, between the isolating cylinder of the tap changer and the tap changer head.
  • Such an embodiment according to the invention has a number of advantages: First of all, it allows a compact construction; no additional pipes or other connection and fastening means are required. A particularly small footprint can be achieved in that the oil conservator can be adapted in the invention to the contour, which is generally circular, of insulating and tap changer head.
  • the tap changer according to the invention moreover, no additional installation work on the oil conservator during assembly, disassembly or opening the step switch are required because the oil conservator as an integral
  • the tap changer Part of the tap changer is formed and can be handled together with this. So it is easily possible to open the tap-changer head and, through the oil conservator, to get to the inside of the oil vessel assemblies of the tap changer - a great advantage for example during maintenance. Finally, the invention allows a complete pre-assembly of the tap changer, then, including the integrated oil conservator, without further

  • FIG. 1 shows a tap changer according to the invention in perspective
  • Figure 2 is an oil conservator of such a tap changer alone.
  • a tap changer 1 which has in known manner an oil vessel 2, which receives the components of the tap changer. At its upper end, the oil vessel 2 has a ⁇ lgefäßflansch 3.
  • the upper terminal of the tap changer 1 forms a tap changer head 4, which has a top flange 5.
  • a motor drive not shown here can be arranged directly. It can also lead from there, also not shown drive train to a separate motor drive, which is usually attached to the outer wall of the transformer. In the prior art, this head flange 5 is directly with the ⁇ lgefäßflansch. 3

It has here as an advantageous feature at least one sight glass 9, and one or more pipe connections 10 to which, for example, a known pressure relief valve can be connected. Finally, it is advantageous to provide the oil expansion vessel 6 still separate crane eyelets 11, which facilitate lifting out.
