Definitions

the invention relates to a tap changer according to the preamble of the claim. Such designs are required for step transformers in the so-called bell-type design.
the object of the invention is to provide a cost-effective and reliable tolerance compensation connection between the cylindrical oil tank with diverter switch insert and transformer housing with a tap changer head for the tap changer mentioned at the beginning. This object is achieved by the means specified in the characterizing part of the claim.
the advantages achieved with the invention are in particular the following:
the movable intermediate flange which brings about tolerance compensation is already connected at the factory by the step switch manufacturer to the cylindrical oil container of the step switch or else to the top flange, so that the O-ring seal is already inserted in the factory and not only during installation of the tap changer must be provided in the transformer. This will damage the sensitive O-ring seal avoided.
the diverter switch insert is torsion-proof and can also be inserted axially secured in the cylindrical oil tank of the tap changer.
the intermediate flange can be screwed to the cylindrical oil vessel of the diverter switch together with a device plate carrying the diverter switch insert.
this requires an additional seal, it leads to a secure locking of the diverter switch insert in the conventional way.
the intermediate flange can be screwed from below to the top flange seated on the flange opening of the transformer housing and that the cylindrical oil vessel is provided on the inside with bushing-type bushing contacts into which the diverter switch insert engages with corresponding contacts in a rotationally secure and axially fixable manner . It is possible to make do with three seals in the area of the tap changer head. However, the mechanical locking of the diverter switch insert must take place via the special bushing contacts located on the oil vessel, in that the diverter switch insert engages with its contacts in corresponding recesses in the bushing contacts.
the tap changer shown in FIG. 1 essentially consists of a cylindrical oil tank 1 with diverter switch insert 2, a tap changer head 3 and a tap selector 4, not shown in detail, which is on the bottom 5 of the cylindrical oil tank 1 is attached.
the cylindrical oil vessel is provided with brackets 6, which are firmly connected to a crossbar 7 attached to the transformer core.
the tap changer head 3 in turn essentially consists of a supporting head flange 10 placed on a flange opening 8 of the transformer housing 9, which is connected to an annular intermediate flange 11 which can be displaced axially in the cylindrical oil vessel 1 and which carries the cover 12 of the tap changer head 3 on its upper side.
the annular intermediate flange 11 is already connected to the cylindrical oil vessel 1 at the factory, and the sensitive O-ring seal 13 has thus already been inserted at the factory.
a pin 14 seated in the cylinder wall of the oil vessel 1 engages in a groove 15 of the annular intermediate flange 11, which on the one hand prevents the intermediate flange 11 from being completely pulled out of the cylindrical oil vessel 1 and on the other hand also provides security against rotation between the annular intermediate flange 11 and the cylindrical oil vessel 1 is. It is readily apparent that for the connection to be established between the top flange 10 seated on the flange opening 8 of the transformer and the intermediate flange 11 basically only the weight of the latter has to be raised.
the diverter switch insert 2 is inserted in the usual way.
the diverter switch insert 2 is both secured against rotation and axially secured by the special design of the bushing contacts 16, in which the diverter switch insert engages with its contacts 17.
the diverter switch insert 2 is namely pressed down over the pressure springs 19 acting on its base plate 18, so that the stops 20 connected to the contacts 17 are firmly anchored in the recess 21 of the bushing contact 16.
three seals for the area of the tap changer head 3 are essentially sufficient. These are the O-ring seal 13 and the two flat seals 22, 23.
the tap changer shown in Figure 3 is constructed analogously to the embodiment of Figure 1.
the intermediate flange 111 is axially displaceable in the head flange 101 the tap changer head arranged.
the pin 141 which engages in a groove 151 of the head flange 101, it is in turn secured against rotation.
the intermediate flange 111 is connected, using its axial displaceability, to the upper end of the cylindrical oil vessel 100, which with its arms 61 is rigidly attached to the active part 7 of the transformer .
a device plate 181 carrying the diverter switch insert is screwed tight, which leads to a secure locking of the diverter switch insert in a conventional manner.
four seals are required in the area of the tap changer head, namely the two O-ring seals 131 and 132, which are already provided at the factory and are protected from damage during final assembly, and the two flat seals 221 and 223.
