Definitions

  • the invention relates to a diverter switch consisting of a manual transmission and a contact arrangement for tap changers of tap transformers.

  • the 'opening speed of the contacts with toggle actuator is necessarily limited in particular at the beginning of each shift movement and thus the maximum attainable shaving 11 lei stung. This is the case because the current interruption at the main contacts of the diverter switch as part of the entire switching process, which is particularly critical at high currents, must take place in the first part of the switching movement to be carried out overall, and a high movement speed is a prerequisite for safe arc quenching.
  • the known diverter switches also have the further common disadvantage that the moving contacts roll on one after the other .
  • the fixed contacts the switching of the permanent contact is dependent on the erosion of the main contact, which leads to functional difficulties.
  • the present invention has for its object to provide a novel Lastumscha Lter in which a high initial opening speed of the respective main and resistance contact is achieved by directly utilizing the rotary movement of the switching shaft actuated by the triggered energy store and in which the actuation of the de-energized switch continues Permanent contact takes place completely independently of the actuation of the main contact and its erosion.
  • the rotary movement generated by the triggering of an energy store can be used directly to actuate the movable contacts; it is not necessary to convert this rotary movement into a combined rolling movement consisting of a rotation and a translation component by means of circular segments, steering levers, toggle levers or similar mechanical arrangements .
  • This kinematics which is much simpler than in the prior art, permits higher opening speeds, in particular of the main contact, and thus, as stated, higher switching powers.
  • the contact actuation according to the invention nevertheless ensures compliance with the actuation order under all circumstances.
  • Another advantage of the invention is that the permanent contact is actuated positively and independently of the movement of the main contact and its erosion, thus achieving a safe switching sequence.
  • the diverter switch can be expanded in a modular manner by having all contacts in a horizontal plane for each phase to be switched, with a plurality of contact planes arranged one above the other being actuated by a single vertical switching shaft, ie for single and three-phase load switching are none different contact or actuation components required.

It can also be seen that the changeover switch 30, which, as described, changes its position “directly” from the drive shaft, which can be rotated in both directions, depending on the switching direction "higher” or “lower", and thus determines which of the contact levers 16 , 19th switchable contacts represent main or resistance contacts for the respective switching stage; a uniform erosion of the contact pieces 17, 18 and 20, 21 is achieved.

Abstract

La présente invention se rapporte à un commutateur de réglage en charge pour commutateurs pas à pas de transformateurs à gradins, lequel est composé d'un mécanisme de commutation et de plans de contact à structure identique disposés au-dessus dudit mécanisme, un plan de contact étant prévu pour chaque phase à commuter. A cet effet, des arbres rotatifs s'étendent depuis le mécanisme de commutation jusque dans le plan de contact. A chaque arbre est relié rigidement, dans chaque plan de contact, un levier de contact pivotant entre deux contacts fixes. A cet effet, des moyens de commutation mécaniques sont disposés dans le mécanisme de commutation, lesquels font en outre pivoter un contact supplémentaire entre des positions fixes de fin de course.
