Definitions
- the invention relates to a power storage for an on-load tap-changer.
- Tap changers are known to be used for uninterrupted switching between different winding taps of a tapped transformer and thus to
- Voltage regulation usually consist of a selector for powerless preselection of those winding tap of the tapped transformer to be switched to and a diverter switch for the actual uninterrupted switching from the previously connected winding tapping to the new, preselected
- the diverter switch has the one for such
- the known power accumulators consist essentially of a lift carriage and a
- guide rods are provided in the known power stores on which the elevator carriage and the jump carriage are mounted longitudinally movable independently. At the same time, the guide rods are the guide for the
- Guide rod encloses.
- the elevator carriage is moved linearly relative to the jump carriage by means of an eccentric connected to the drive shaft, as a result of which the force storage springs located therebetween are tensioned. If the elevator carriage has reached its end position, the locking of the jump carriage is released. In other words, an initial slow rotational movement of the drive shaft is used to translate a lift carriage in order subsequently to the turn translational movement of the jump carriage into a rotary
- Object of the present invention is therefore to provide a force accumulator of the type mentioned, which makes the time-consuming multiple conversion of a rotary motion in a translational movement dispensable. In particular, this should be achieved with only simple technical means and few individual components.
- the general inventive idea is to use an energy store for a
- Gearing engagement can be brought, in turn, in turn each roll on a correspondingly toothed inner peripheral side of a first, larger diameter of a ring gear.
- a wing-shaped web shaft mounted rotatably mounted on the rotatable drive shaft, in which each wing on the one hand with a
- Planet gear formed further gear and on the other hand is in operative connection with the first end of a spring.
- an arm-shaped frame is provided, which surrounds the second, smaller and designed as an output shaft diameter of the ring gear and on which, on the respective arm, the second end of the corresponding spring is fastened, such that the respective springs between the corresponding receptacles by means of a rotary movement of the web shaft are on the one hand tensioned and on the other hand enable the web shaft, in the case of the actual fast switching operation of the diverter switch, against the elevator direction in a rotary motion.
- this energy store dispensed according to the invention on the complex technical conversion of an initial translational elevator movement in a fast, required for the actual load switching, rotary main motion for actuating the switch contacts.
- Figure 1 is a sectional view of an energy storage device according to the invention for an on-load tap-changer.
- a rotatable drive shaft 1 Extending in the longitudinal direction, a rotatable drive shaft 1 is centrally provided, on which a sun gear designed as a first gear 2 is fixedly mounted, which is in meshing with a plurality of planetary gears formed further gears 3, wherein the other gears 3 in turn at the corresponding along the toothed inner peripheral side of a first, larger diameter of a ring gear 4.
- the ring gear 4 has an internal toothing, which can be brought into toothing engagement with a plurality of planetary gears 3, which in turn are in meshing engagement with a central sun gear 2, which in turn is rotatably connected to the drive shaft 1.
- double hook-shaped locking elements 5 are provided on the outer peripheral side of the first, larger diameter of the ring gear 4 a plurality, each offset by 120 ° to each other.
- double hook-shaped locking elements 5 are provided on the outer peripheral side of the first.
- the retaining hook 8 is formed in two parts, such that the two mirror-inverted holding hooks 8.1 and 8.2, each mounted rotatably about the longitudinal bolt 7, hook into the respective locking element 5 on both sides.
- a spring 20 is tensioned to accomplish a re-locking of the ring gear 4 at the corresponding locking position 5 at the end of a switching operation of the on-load tap-changer.
- the spring 20 is designed as a leg spring, which is guided and held at the lower end of the holding mechanism 6 by the longitudinal bolt 7.
- the two spring legs of the spring 20 are in operative connection with the holding hooks 8.1 and 8.2.
- the symmetrically constructed holding mechanism 6 is fixedly connected to two axes, of which due to the symmetry and the sectional view of the invention
- Retaining mechanism 6 are each mounted along the axes 21 spring clips 23 and ensure their biasing force for the centering of the holding mechanism 6 in the unloaded state of the energy accumulator. Spring rate, preload and maximum
- Holding mechanism 6 along the axes 21 is possible.
- the lower portion of the ring gear 4 has a second, smaller diameter and is designed as an output shaft 9, at the example, by means of a splined coupling, not shown, the operative connection to the actual diverter switch is produced.
- the drive shaft 1 is mounted centrally in the interior of the ring gear 4.
- the ring gear 4 is in turn received rotatably stored in an arm-shaped frame 10.
- a flight-like web shaft 1 1 is arranged, which is rotatably mounted by means of a bearing on the same.
- the respective wings of the web shaft 1 1 are each by means of a bolt 12 with one of the planetary gears formed as additional gears 3 in
- each substantially flat and rectangular shaped trigger 13 are mounted, which have a bevelled ramp surface 14.
- first receptacles 15 for corresponding springs 16 which are designed as tension springs, which are then connected via a further, second receptacle 17 with the respective arm of the frame 10 and between the first
- Receivers 15 and the second receptacles 17 in the event of rotation of the web shaft 1 1 can be stretched. Attached is the further, second receptacle 17 on the arm-shaped frame 10, also by means of a bolt 18th
- a defined torque is transmitted to the drive shaft 1 via a motor drive, not shown, while the ring gear 4 is fixed on both sides rotatably on the latched at the respective detent position retaining hook 8.
- the fixedly mounted on the drive shaft 1 first gear 2 drives acting as planet gears further gears 3, which in turn roll along the toothed inside of the latched ring gear 4.
- a rotation of the web shaft 1 1 and thus a tensioning of the springs 16 is effected.
- the clamping operation is completed and the ramp surface 14 of the corresponding trigger 13 look directly at a pin 19 of the holding hook 8 at. Will the 360 ° rotational movement of the
