Definitions

  • the invention relates to a tap changer based on the reactor switching principle uninterrupted load switching according to the preamble of the first Claim.
  • Such a tap changer is used in connection with a power transformer for uninterrupted switching between different winding taps of this transformer and is thus used for uninterrupted voltage regulation.
  • Switching impedances are provided which avoid a step short circuit during the slow switchover from one winding tapping to the next and are dimensioned for the permanent load.
  • Such a tap changer is already known from the company publication "Load Tap Changer Type RMV II” from Reinhausen Manufacturing, Humboldt, USA, imprint RM 05/91 - 1094/5000.
  • vacuum switching cells are used for load switching.
  • N and n + 1 are adjacent taps of the tap winding of the transformer.
  • P1 and P2 are the movable selector contacts to be actuated during the switchover, R1 and R2 are the switchover impedances already explained.
  • a vacuum switching cell V is connected between the two branches, and the corresponding connection to the load derivation L is established by a by-pass switch B.
  • the by-pass switch B can - depending on the position - either of the two movable ones Selector contacts P1, P2, both individually and together with the load conductor L connect.
  • the movable by-pass contacts are articulated to one another and to the load conductor L.
  • Each of the two fixed by-pass contacts is electrically connected to one of the movable selector contacts R1, R2 on its side facing the vacuum switch cell.
  • the by-pass switch bridges the two fixed by-pass contacts and connects them together with the load conductor L.
  • this connection between the two fixed by-pass contacts and thus the movable selector contacts is interrupted; in the switching sequence shown in FIG. 3, the by-pass switch only connects the movable selector contact P1 remaining on the original winding tap n of load transfer L.
  • the object of the invention is a further developed step switch of the generic type to specify with a by-pass switch that is simple, made up of just a few Individual parts exist, is also easy to operate and has a high current carrying capacity has small dimensions.
  • the two mechanically rigidly coupled, movable by-pass contacts together with every switching movement. This has the Another advantage of simultaneous self-cleaning of the contact surfaces of both movable by-pass contacts of any foreign layers.
  • the step switch has a switching shaft 1 for actuating the by-pass switch, which is connected to the drive, generally the motor drive, of the step switch.
  • a control gear (not shown) ensures that all contacts are actuated in the sequence provided for in the sequence shown in FIG. 3.
  • the shaft 1, which actuates the by-pass switches of all three phases, performs a rotary movement by a certain angle and then back to the starting position each time the load is switched, depending on the switching direction.
  • fixed by-pass contacts 3.1 and 3.2 are attached to insulating plates (not shown here). arranged. These are segmented in a concentric circular path around the shaft 1, so that they are swept by the outer contact ends of the movable by-pass contacts 2.1, 2.2 when they rotate. Their length a and the distance b between them is dimensioned so that they can be bridged by both movable by-pass contacts and both movable by-pass contacts rest on each of the two fixed by-pass contacts together can.
  • the load discharge is formed by an electrically conductive concentric slip ring 4, on which both movable by-pass contacts 2.1, 2.2, each with their inner contact ends, slide.
  • the movable by-pass contacts 2.1, 2.2 are each formed symmetrically perpendicular to the direction of movement, ie the outer and inner contact ends are identical.
  • the two movable by-pass contacts 2.1, 2.2 are advantageously screwed onto the contact carrier 2, so that they can be exchanged in a simple manner or, in the case of special requirements, can also be exchanged for wider contacts or contacts made of another material. This is all possible without further ado, the only requirement is that the above-described relations between dimensions a, b and c are observed.
