  • Patent number: 8947188
    Abstract: The invention relates to a tap changer for the interruption-free switchover between winding taps of a tap-changing transformer. Furthermore, the present invention relates to a novel vacuum interrupter which is particularly suitable for such a tap changer. The tap changer according to the invention is based on the general concept of combining in each case one main contact (V1) and one mechanical switching means (U1), connected in series therewith, of a first load branch and an additional resistive contact (V3) of a second load branch in only a single vacuum interrupter (1) with a common housing (5).

  • Patent number: 8927886
    Abstract: The present invention relates to a load transfer switch for a tap changer, comprising permanent main contacts that switch powerlessly for each phase. The general inventive concept lies in connecting the fixed permanent main contacts of side A or B of the load transfer switch by means of a movable rail-shaped permanent main contact that establishes an electrical connection to the corresponding permanent main contacts of the load line only in the end positions of the movable rail-shaped permanent main contact and in addition only provides for a single deflection for actuation, which connects in a purely compressive manner the plurality of contact fins of the corresponding fixed permanent main contact, which contact fins are connected in a resilient, articulated manner.

  • Patent number: 8633312
    Abstract: The present invention relates to compounds of the formula I wherein R1, R2, R3, R4, X and Y have the meanings given in the description. The compounds have an action which is immunomodulating and inhibits or regulates the release of IL-1? and/or TNF-?. They can therefore be used for treatment of diseases connected with a disturbance in the immune system.

  • Publication number: 20130341166
    Abstract: The invention relates to an on-load tap changer for switching between winding taps of a step transformer without interruption, comprising a separate selector for preselecting the winding tap to be switched to without control current, and a separate load transfer switch for actually transferring the load from the previous to the preselected new winding tap. The invention further relates to an energy store having at least one energy store spring that is first tensioned for each load transfer by a rotating drive shaft and that abruptly actuates the load transfer switch after being triggered. According to the invention, a gear is provided by means of which the energy store can be tensioned after mechanical freewheel is provided between the gear and the energy store, such that the energy store can be tensioned after a time delay, and a further mechanical freewheel (17) is provided between the energy store and a step-by-step motion linkage actuating the load transfer switch.

  • Publication number: 20130057248
    Abstract: The invention relates to an on-load tap changer for step transformers, which has one main current branch and one auxiliary current branch for each of the two winding taps to be switched. In each main current branch and auxiliary current branch, switching is accomplished by means of a vacuum switching tube. According to the invention, an additional mechanical contact is provided in each of the main current branches and in each of the auxiliary current branches between the respective winding tap to which said branch is electrically connected and the respective vacuum switching tube in said branch. Said mechanical contacts are switched in such a way that the vacuum switching tubes in the main current branch and the auxiliary current branch of the unconnected winding tap can be galvanically isolated from the unconnected winding tap.

  • Patent number: 8119939
    Abstract: The invention relates to an on-load tap changer having an energy storage mechanism for changing over, without any interruptions, between different winding taps of a tap-changing transformer on load. According to the invention, the energy storage mechanism has one or more compression springs, which are tensioned at the beginning of a changeover operation. In comparison with the tensile springs used to date with such energy storage mechanisms, the compression springs have markedly greater long-term strength.
