Definitions

  • the invention relates to a power storage for an on-load tap-changer.
  • On-load tap-changers are used for uninterrupted switching between different winding taps of a tapped transformer under load. Since this changeover usually takes place abruptly, on-load tap-changers generally have a force store.
  • Such a power storage is known from DE-PS 19 56 369 and DE-PS 28 06 282 already known. It is mounted at the beginning of each actuation of the on-load tap-changer by its drive shaft, d. H. curious; excited.
  • the known power storage essentially consists of an elevator carriage and a jump carriage, between which power storage springs are arranged as energy storage.
  • the guide rods form the guide for the force-storing springs, such that in each case one force-storing spring in each case encloses a guide rod.
  • the elevator carriage is moved linearly relative to the skid carriage by means of an eccentric connected to the drive shaft, thereby tensioning the energy storage springs therebetween. If the elevator carriage has reached its new end position, the locking of the jump carriage is released. This follows now abruptly, as standing under the force of the tensioned power storage springs, the previous linear movement of the elevator carriage also linearly. This sudden movement of the jump carriage is converted into a rotational movement of an output shaft. This in turn serves to actuate the on-load tap-changer, i. H. to switch between the previous to a new winding tap under load.
  • both elevator carriage and jumping carriage on an open 4-point storage they are on - seen in the direction of movement - upper and lower end respectively mounted on the two parallel guide rods and are guided by these.
  • the well-known power storage places high demands on the parallelism of the guide rods and the accuracy of the moving parts as a whole, since jamming or even a stiffness of elevator or jump sled must be avoided.
  • a stiffness of the elevator carriage would cause unacceptably large actuation forces; a stiffness of the jump carriage could cause this does not reach its final position and thus the switching of the on-load tap changer can not be properly completed, since the energy storage does not latch in its new end position.
  • the object of the invention is to provide a force accumulator of the type mentioned, which has a simple structure and a particularly high reliability.
  • Fig. 1 shows a force storage device according to the invention in a lateral view
  • Fig. 4 is a schematic representation of the principle of the three parallel
  • Figures 1 to 3 show a force storage device according to the invention in different representations, not all items described in more detail below recognizable in each representation and thus not all reference numerals are entered.
  • the force-storing springs and the force-storing carrier have been omitted for better illustration.
  • an eccentric disc 2 which is connected to a drive shaft 1 is also provided in the force accumulator described here, which actuates an elevator carriage 3 by acting on the driver blocks 4 and 5 arranged at the top and bottom in the direction of movement of the elevator carriage 2.
  • the force accumulator has three parallel extending, along the direction of movement of the elevator carriage 3 extending guide rods 6, 7 and 8, two of which, in the example shown, these are the guide rods 6 and 7, of power storage springs 12, 13 are enclosed.
  • the elevator carriage 3 has at its one end two linear bearings 9 and 10.
  • the linear bearing 9 encloses the guide rod 6, the linear bearing 10 encloses the guide rod 8.
  • the elevator carriage 3 has only a single linear bearing 11, which encloses the guide rod 7.
  • the energy storage springs 12 and 13 each extend around one of the two guide rods 6 and 7, respectively. They are fixed in the direction of movement above or below in each case a displaceable spring bar 14 and 15 with one of their ends and are supported there. The function of the spring bars 14, 15 will be explained later in more detail.
  • the described three guide rods 6, 7, 8 are attached at its two ends to a force storage carrier 17, to which the other stationary components of the force accumulator according to the invention are attached.
  • the sequence of movements in an elevator of the force accumulator is as follows:
  • the drive shaft 1 begins to rotate, with it the eccentric disc 2, which slides on the corresponding driver block 4, 5 and thus shifts the elevator carriage 3 in the longitudinal direction.
  • the force storage springs 12, 13 are tensioned.
  • these power storage springs 12, 13 are biased maximum.
  • the jump slide 16 is still locked by laterally up and down in the direction of movement latch lever 21, 22 so that it can not follow the direction of movement of the elevator slide 3.
  • a suitable actuator for the rollers 23 and 24 may, for. B. a vertical, laterally arranged on the elevator carriage 3, be downwardly extending actuating sheet whose presentation has been omitted here for reasons of clarity, since it would have hidden many important other components.
  • Such an actuating plate may be fastened to a screw connection 33 indicated in FIG.
  • spring bars 14 and 15 have already been briefly described, which are arranged displaceably on the guide rods 6 and 7 and respectively form upper and lower abutment for the power storage springs 12 and 13.
  • Spring webs 14, 15 on the one hand and elevator slide 3 and jump carriage 16 on the other hand are designed such that the spring bars 14, 15 abut both upper and lower limits of the elevator carriage 3 and the jump carriage 16 in the direction of movement and taken by these two components in both directions of movement can be.
  • the jump-like linear movement of the jump carriage 16 is by known technical means, for.
  • one or two rollers 31 are provided for this purpose, which are fastened to the jump carriage 16 and are guided in a groove 32 of the output element 26.
  • This output element 26 is connected to an output shaft, not shown here, in connection, which ultimately jumped the on-load tap changer, d. H. initiates the sudden changeover between two winding taps under load.
  • the rollers 31 are fastened by means of a carrier 34 on the jump carriage 16.
  • an additional pressing device is arranged in the force storage device according to the invention.
  • Such Nachdrück worn should ensure that even under difficult operating conditions, for example, at low temperatures and very tough the energy storage enclosing oil with certainty the new end position is reached and the energy storage latched in this new position again. It consists of in the direction of movement at the top and bottom of the jump carriage 16 arranged drivers 27 and 28, with a roller pin 29 on the Eccentric disc 2 correspond.
  • the roller pin 29 is arranged such that it shortly before the end of the movement of the jump carriage 16, ie shortly before reaching its new end position, depending on the position of the jump carriage 16 coincides with either the driver 27 or the driver 28 and thus by the still rotating Eccentric disc 2 additionally pushes the jump carriage 16 in the new end position - hence the name Nachdrück arthritis.
