Definitions

  • the invention relates to a tap changer according to the preamble of the first claim.
  • Such a tap changer is already known from DE 42 37 165 C1.
  • the switching mechanism consists of an elevator carriage and driven part.
  • the elevator carriage is connected to a mechanical contact that acts as a pre-selection contact, which can be brought into contact with each of the fixed step contacts and with its free end slides on a contact rail, which in turn is connected to the load discharge via at least one contact resistance and a first vacuum switch ,
  • the output part is connected to a trailing mechanical switch contact, which can also be connected to each of the fixed step contacts and in turn is connected to the load discharge via a second vacuum switch.
  • the object of the invention is to provide a tap changer of the generic type, the high switching capacities, i.e. the carrying of high load currents, permits and at the same time high Functional security offers.
  • auxiliary contact HK which is fixedly connected to and movable with an elevator carriage (not shown here) which can be driven continuously.
  • the auxiliary contact HK grinds on a contact rail KS, which in turn is electrically connected to a load lead L via a switching resistor R and a first vacuum switch VH.
  • a second mechanical contact, the switching contact SK is fixedly connected to and movable with an output part - which is likewise not shown here - which can be tracked to the elevator carriage after it has been triggered. It is connected to the load discharge through a series connection of a second vacuum switch VS and a third vacuum switch VL. Instead of the series connection described, only a single vacuum switch can be present in this branch.
  • the contact rail KS is also firmly connected to the driven part.
  • a further mechanical contact S o is provided on the driven part, which consequently can also be moved with it.
  • This fixed contact S o is arranged in such a way that it is connected by an additional contact point HKS of the auxiliary contact HK in the stationary state, ie when mechanical auxiliary contact HK and mechanical switching contact SK are present at the same fixed step contact n.
  • Figure 3 shows a modified embodiment of the invention.
  • the latter is designed so that two individual contact rail parts KS A and KS B are present, between which the additional fixed contact S o is located.
  • the two contact rail parts KS A , KS B and the additional contact S o are fixed and fixed with respect to their relative position to one another on the driven part and are moved with it.
  • the function of this embodiment is unchanged, as can be seen from the switching sequence shown in FIG. 4.

Claims (1)

  1. Commutateur de prises à commande linéaire des contacts, comportant des contacts de prises, fixes, répartis le long d'un trajet et venant en saillie à l'intérieur du commutateur, pour être commutés par un mécanisme de commutation coulissant,
    le mécanisme de commutation étant formé d'un chariot de remontage à entraínement direct et d'une partie de sortie qui, après déclenchement, suit le chariot de remontage par un mouvement brusque,
    le chariot de remontage étant relié à un contact auxiliaire mécanique de présélection qui peut être mis en contact avec chaque contact de prise, fixe, et par lequel on met en liaison électrique une résistance de passage et un premier commutateur à vide avec la ligne de sortie de charge,
    la partie de sortie étant reliée à un contact de commutation mécanique qui peut également être mis en contact avec chaque contact fixe de prise, et qui est relié par un second commutateur à vide ou par un montage en série composé d'un second et d'un troisième commutateur à vide, à la ligne de sortie de charge,
    et à l'état stationnaire, le contact auxiliaire mécanique et le contact de commutation mécanique sont appliqués contre le même contact de prise, fixe,
    caractérisé en ce que
    le contact auxiliaire mécanique (HK) de présélection comporte un autre point de contact (HKS),
    la partie de sortie comporte un contact mécanique fixe (S0) supplémentaire, relié électriquement, directement ou par au moins une autre résistance de passage (R0), à la ligne de sortie de charge (L), et
    à l'état stationnaire, l'autre point de contact (HKS) du contact auxiliaire mécanique de présélection (HK) est appliqué contre le contact supplémentaire (S0) de façon que le contact de prise fixe (n, n+1) qui est chaque fois commuté, soit relié électriquement directement à la ligne de sortie de charge (L) sans passer par des commutateurs à vide (VS, VL).
