Definitions

  • the invention relates to an energy store for an on-load tap changer and an on-load tap changer with an energy store.
  • An energy store often also referred to as an energy store, is used in an on-load tap changer with an output shaft, an input shaft and a diverter switch to convert a continuous, slow rotary movement of the output shaft, which is driven by a motor at a constant speed, into a sudden, rapid rotary movement of the input shaft that drives the diverter switch.
  • Numerous energy stores are already known which enable the sudden rotation of the drive shaft with the aid of a storage spring. The principle is always the same: the output shaft, driven by the motor at a constant speed, tensions the storage spring to a maximum point, and after this maximum point is exceeded, the storage spring relaxes suddenly and drives the drive shaft suddenly.
  • DE 28 06 282 B1 EP 0 355 814 A2 .
  • DE 10 2005 027 524 B3 DE 10 2005 027 527 B3 .
  • DE 10 2010 020 130 A1 and EP 2 760 034 A1 each describe an on-load tap-changer with an energy store, which comprises a storage spring, a gear, a frame for the gear, an eccentric, a pull-up slide and a spring slide.
  • the transmission includes an input hub and an output hub. Because of these sledges, such energy stores are also referred to as sled energy stores.
  • the output shaft is connected to the input hub in a rotationally fixed manner.
  • the input hub is non-rotatably connected to the eccentric.
  • the eccentric is positively connected to the mounting slide.
  • the storage spring is supported between the pull-up slide and the spring slide.
  • the pull-up slide and the jump slide can move back and forth independently of one another between two end positions relative to the frame along a linear guide.
  • the jumping sled is positively connected to the output hub.
  • the eccentric forms, together with the mounting slide, a tensioning element which is designed such that it engages the tensioning element and then when the input hub is rotated, the storage element tensions, and the jump carriage forms a relaxation element which is designed such that it engages the storage element to drive the output hub and then drives the output hub when the storage element is relaxed.
  • DE 10 2006 008 338 B3 and DE 10 2009 034 627 B3 each describe an on-load tap-changer with an energy store, which comprises a storage spring, a gear, a frame for the gear, a drive element in the form of a gearwheel with two axially projecting stop faces and a crank with a crank pin.
  • the transmission includes an input hub and an output hub. Because of this crank, such energy stores are also referred to as crank energy stores.
  • the output shaft is connected to the input hub in a rotationally fixed manner.
  • the input hub is non-rotatably connected to the drive element.
  • the drive element and the crank can rotate back and forth relative to one another between a first end position and a second end position.
  • the stop surfaces correspond to the crank in such a way that the first stop surface bears on a first side of the crank in the first end positions and the second stop surface bears against a second side of the crank in the second end position, these sides being opposite one another. Consequently, the drive element is positively connected to the crank in these end positions.
  • the storage spring is pivoted with a free end on the crank pin and is pivotably supported on the frame with a fixed end. The free end can move back and forth between two end positions relative to the fixed end along a linear guide.
  • the crank is coupled to the output hub.
  • the crank together with the drive element, forms a tensioning element which is designed such that it engages with the storage element for tensioning and then tensions the storage element when the input hub is rotated, and the crank forms a relaxation element which is designed such that it is for driving the output hub attacks the storage element and then drives the output hub when the storage element is relaxed.
  • the invention proposes an energy store according to claim 1.
  • variable translation means is here understood to mean, for example, a translation means with variable translation, that is to say that its translation depends on the angular position of the input hub or on the angular position of its input side, which is coupled to the input hub and, in particular, connected in a rotationally fixed manner.
  • the translation means can in particular be designed in such a way that when the input hub rotates from a first angular position to a second angular position, the translation becomes larger or smaller or the sign changes or remains the same or is infinite.
  • the translation means of the proposed energy store enables an oscillating pivoting movement of the output hub between its first and second angular positions, regardless of the direction of rotation of the input hub.
  • An oscillating pivoting movement is understood here to mean that the output hub first rotates in a first direction from a predefined first angular position to a predefined second angular position when the input hub is rotated in a first direction from a predefined first angular position by a predefined differential angle, and that , then the input hub either in an opposite, second direction back to its first angular position or further in the first direction the difference angle is rotated, then the output hub rotates in an opposite, second direction from its second back to its first angular position.
  • the translation means when relaxing and / or driving the output hub, enables the tensioning element to be traversed relative to the tensioning element at a desired and / or predetermined speed, which can in particular be greater than the speed during tensioning.
  • the relaxation and / or driving of the output hub can take place more slowly than under normal operating conditions and even so slowly that the tensioning element catches up with the relaxation element attacks on the storage element as when clamping.
  • the translation means enables the expansion element to be re-pressed, in that the input hub drives the output hub directly and without delay via the tensioning element and the expansion element.
  • the tensioning element and the relaxation element can be designed in any manner as required, for example as in the case of a slide energy store or a crank energy store.
  • the crank in particular forms at least part of the tensioning element and / or at least part of the relaxation element.
