Definitions

  • the invention relates to a cylindrical oil container for tap changers of tap transformers according to the preamble of claim 1.
  • the flange-mounted metallic base part is usually fastened by a larger number of screws or rivets which penetrate the cylinder wall of the oil vessel and then sit firmly in the flange (DE-U-7114665).
  • This type of fastening of the metallic base part is complex.
  • Another problem lies in the fact that the bottom of the oil container, which is made of metal, can assume an undetermined electrical potential when the tap changer is in operation, which is why the bottom is linked to the tap potential of the tap changer by an electrical line if possible.
  • the object of the invention is to achieve an improvement both with regard to the connection between the base and the cylinder and also with regard to the potential carry-over in the aforementioned oil vessels for tap changers. This object is achieved according to the invention by the means specified in the characterizing part of claim 1.
  • the advantage achieved by the invention lies in the following: For the attachment of the base to the insulating cylinder, no additional holes have to be provided in the cylinder wall, but the already existing discharge contacts, which are firmly anchored in the cylinder wall, can be used to attach the base .
  • the recess for the O-ring seal can be open at the top, since it is covered by the drain ring located in the interior of the oil container, so that the inserted O-ring cannot slip out of the recess.
  • the base part is therefore free from undercuts and can be produced inexpensively as a molded part made of isofier substance.
  • the connecting elements between the floor and the discharge contacts are from the start. on discharge potential. An indefinite potential can no longer occur in connection with the floor, and therefore no special electrical connection lines are required for articulating a metallic floor part.
  • the bottom part is expediently provided with four eyelets which are evenly distributed around the circumference and which, in terms of their number and arrangement, match the arrangement of e.g. correspond to four discharge contacts in the insulating cylinder.
  • the eyelets can be integrally formed on the base part together with a foot projecting downwards, each foot merging into a rib tapering towards the center of the cylinder to reinforce the base part.
  • the oil container essentially consists of an insulating cylinder 1 with a bottom part 2 flanged to it. A cover part also flanged to the top and closing the oil container is not shown in detail.
  • the base part 2 is designed as a glass-fiber-reinforced molded part made of insulating material and engages with an edge 3 in the clear width of the insulating cylinder 1.
  • an O-ring seal 5 is arranged, which thus lies sealingly on the edge 3 as well as on the inner wall of the insulating cylinder 1.
  • the recess 4 for the O-ring seal 5 is practically covered by the discharge ring 6, which is located on the inner wall of the insulating cylinder 1, when the base part 2 is inserted in the insulating cylinder 1, so that the O-ring seal 5 cannot slip out of the recess 4.
  • the discharge ring 6 is held by means of several connecting screws 7, which are seated in the wall of the insulating cylinder 1.
  • the connection screws 7 also serve as lead contacts for connecting an external lead of the tap changer.
  • special tension bolts 8 which are inserted through an eyelet 9 of the base part and thus serve to fasten the base part to the insulating cylinder 1.
  • the base part 2 is brought into contact with the protruding eyelets on the end face of the insulating cylinder.
  • a foot 10 is also formed on the base part, which merges towards the center into a rib 11 reinforcing the base part.
  • the feet 10 serve to securely park the oil container or the fully assembled tap changer.
  • On the inside of the bottom part 2 there is further provided a bearing 12 for receiving a switching shaft of the tap changer, not shown in detail.
  • the control shaft is used to actuate movable contact systems that work with fixed contacts 13 seated in the wall of the insulating cylinder 1.
