摘要： The invention relates to a tap changer having vacuum interrupters for switching over between winding taps of a tapped transformer without interruption. The tap changer according to the invention having vacuum interrupters is based on the general idea of combining the functionalities of at least one conventional vacuum switching contact which switches under load and a further mechanical switching means according to the prior art in just one single vacuum interrupter with two separately moving contact systems.

摘要： 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). The vacuum interrupter (1) according to the invention is furthermore based on the general inventive concept of replacing the functionalities of two required vacuum interrupters in accordance with the prior art and an additional mechanical switching means with a single vacuum interrupter (1) according to the invention by virtue of combining the design of a vacuum interrupter (1) with a plurality of moveable contact systems (I, II, III), which are arranged in separate vacuum interrupter chambers (2, 3, 4) which are sealed with respect to one another.

摘要： A vacuum interrupter has a tubular insulating body and a contact system with a moving contact and a fixed contact each connected to power supply bolts, which are passed out of the vacuum interrupter in a vacuum-tight manner. A control electrode is DC-connected to the fixed-contact power supply bolt. A damping shield, which is arranged on the insulating body, is conductive and overlaps the control electrode in an axial direction. The vacuum interrupter has good shielding properties while at the same time improving the dielectric insulation. The control electrode extends out in the form of a toroid in the region of overlap with the damping shield, the damping shield is drawn inwards so as to correspond to the toroid, and the fixed-contact power supply bolt is constricted so as to correspond to the contour of the damping shield and the constriction is fitted such that the drawn-in region of the damping shield extends around the constriction.

摘要： A tap changer for uninterrupted switching between winding taps of a tapped transformer has first and second load branches for each phase to be switched. Each load branch has a main vacuum switch and in parallel thereto a series connection of a switch-over resistance and a respective auxiliary vacuum switch. First and second vacuum switching tubes each contain the main vacuum switch of the respective first and second load branches and the auxiliary vacuum switch of the other of the load branches.
