Definitions

  • the invention relates to a contact arrangement for step selectors of step transformers for connecting a contact ring with circularly arranged step contacts according to the preamble of the first claim.
  • Such contact arrangements are already known (DE-AS 11 93 145, DE-OS 23 54 173).
  • a contact bridge is provided between a slip ring arranged concentrically around the movement axis and circularly arranged fixed step contacts, which contains two groups of contact lamellae, which are oppositely opposed to one another, which are individually movable and resiliently mounted in the contact bridge housing and each from above or below press the force of the springs to make contact onto the slip ring or the fixed step contact to be connected to it.
  • the radial distance between the slip ring and the tap changer results from the number of tap contacts and the required voltage with which the tap changer should be applied. It is therefore necessary, on the one hand, to make the contact bridges of different lengths and, on the other hand, to design the contact bridge housing differently depending on the expected voltage.
  • the known contact arrangements only insufficiently compensate for height tolerances that are unavoidable during manufacture of the step contacts, since the possible deflection of the individual contact lamellae must remain narrowly limited in order to rule out jamming of the lamellae in the contact bridge housing and jamming of the individual lamellae when running onto a step contact.
  • the invention makes it possible that only the total length of the contact lamellae must be adapted to the radial distance between the selector column and the fixed step contacts, the position and dimension of the contact pressure spring receptacle being the same regardless of the length for all contact lamellae, while that is the leading factor of the contact lamellae and holding component always the same contact frame can be used, which can advantageously be produced in a simple manner from sheet metal, especially since no electrical requirements are placed on it, since it is voltage-shielded from the two-part contact bridge housing.
  • the two-part contact bridge housing is manufactured, for example, from cast iron and is dimensioned such that it acts as an electrode and takes over the complete shielding of the entire contact arrangement.
  • the invention allows double and resilient guidance of both the contact blades in the frame and of the frame in the two-part contact bridge housing, and also larger horizontal differences between the contact ring and the individual step contacts safely and easily balance.
  • Upper contact lamellae 5.1 and lower contact lamellae 5.2 rest on both sides on the contact ring 2 and on the step contact 4 to be connected to it.
  • the pressure is applied by contact pressure springs 7, which engage in contact pressure spring receptacles 6 of the upper and lower contact plates 5.1 and 5.2 and are supported in spring abutments 9 of a surrounding contact frame 8.
  • the contact frame 8 consists of a sheet metal construction guiding the upper and lower contact plates 5.1 and 5.2 and at the same time fixing their movement with two fastening points 10.
  • the position and spacing of the contact pressure spring recesses 6 are, regardless of their length, in all contact plates 5.1 and 5.2 the same, so that the same contact frame 8 can always be used for guiding and fixing.
  • This contact frame 8 is in turn enclosed with the interposition of a frame spring 12 or also several such frame springs with play on all sides by a split contact bridge housing 14, consisting of an inner housing part 14.1 facing the selector column 1 and an outer housing part 14.2 facing the step contacts 4, the housing parts 14.1 and 14.2 are connected to one another by one or more spacer bolts 16.
  • the frame spring 12 engages in a spring guide 13 of the contact frame 8 and is supported on the other hand in a recess 15 of the corresponding housing part 14.1 or 14.2.
  • a plurality of frame springs 12 can also be arranged on the upper and lower side between the contact frame 8 and the respective housing part 14.1 or 14.2, in which case it has proven advantageous to compensate for the dead weight of the contact frame 8 and the contact plates 5.1 and 5.2 to use springs with greater spring force on the underside and / or to arrange disks 11 in the lower recesses 15 of the contact bridge housing 14.
