Definitions

  • the invention relates to a tap changer based on the reactor switching principle uninterrupted load switching using vacuum switch cells
  • a tap changer is used in conjunction with a power transformer uninterrupted switching between different winding taps uses this transformer and thus serves for uninterrupted Voltage regulation.
  • the invention relates to tap changers according to the first-mentioned reactor switching principle.
  • Such a tap changer is already known from the company publication "Load Tap Changer Type RMV II” from Reinhausen Manufacturing, Humboldt, Tenessee, USA, imprint RM 05/91 - 1094/5000.
  • vacuum switching cells are used for the actual load switching, which have numerous advantages over mechanical load switching contacts, in particular also a long service life.
  • vacuum switching cells there is no contamination of the surrounding oil, which would occur in mechanical load changeover contacts due to arcing and contact erosion.
  • N and n + 1 are adjacent taps of the step winding of the transformer.
  • P1 and P2 are the movable selector contacts to be actuated during the switchover, R1 and R2 are the switchover impedances already explained.
  • a vacuum switching cell V is connected between the two branches, and the corresponding connection to the load conductor L is established by a by-pass contact B.
  • the two movable selector contacts are both connected to the same tap, ie to the same fixed selector contact.
  • one movable selector contact rests on a first fixed selector contact and the other movable selector contact on the adjacent further fixed selector contact. This sequence is repeated with every further load switch.
  • the known tap changer has a three-phase design and consists of an oil-filled housing that has selector contacts, preselector contacts, vacuum switch cells and by-pass contacts.
  • the term “preselector contacts” is intended to mean both the contacts for a possible coarse selector and for a possible turner. These two circuit variants are well known from the prior art.
  • the drive mechanism for actuating the individual contacts and the vacuum switch cells is located in a housing part which is arranged separately to the side of it.
  • a terminal board is provided in the housing, on which the selector and reversing contacts are arranged, spatially separated for each of the three phases to be switched.
  • the corresponding vacuum switch cell and the associated by-pass contacts are arranged in each case on further circuit boards for each phase:
  • the fixed and the movable by-pass contact On one side of the other board, which faces the terminal board, are the fixed and the movable by-pass contact, on the other side of the board is the vacuum switch cell, each with an energy accumulator for its actuation.
  • a corresponding energy store is known from DE 41 26 824.
  • All switching elements of all phases are actuated by a single insulating shaft, which from the drive mechanism located in the side housing part, the entire housing goes through.
  • three Maltese drives are provided, one for each phase are also provided on the terminal board. These Maltese drives generate from the rotary movement of the drive shaft, both the movements for actuation the selector and reversing contacts as well as the movements for actuating the by-pass contacts and the tensioning of the energy accumulator for actuating the corresponding one Vacuum switch cells in the predetermined switching sequence, as shown in Fig. 1.
  • a single insulating shaft actuates three separate Maltese drives.
  • Each Maltese drive in turn actuates the elements of the respective phase arranged on the terminal board, namely the selector contacts and, by means of a separate bolt on the Maltese, the reversing contacts.
  • the elements of the respective phase namely the by-pass contact and the energy accumulator of the corresponding vacuum switching cell, which are arranged on the associated further circuit board, are actuated by means of a double-sided groove in a rotatable disk.
  • Such a disk provided with a double-sided control contour is known from DE 40 11 019 known.
  • Maltese drives in particular, are complicated structures that are subject to high accuracy requirements and are therefore complex to manufacture.
  • the object of the invention is to simplify the step switch of the generic type and to reduce the number of individual parts required, in particular also the number of necessary Maltese drives. Furthermore, it is an object of the invention to simplify the actuation of the by-pass contacts on the one hand and the vacuum switching cells on the other hand, and, in connection with this, to provide a simple but nevertheless reliably functioning energy store.
  • Another advantage is the particularly simple design of the energy store for actuating the respective vacuum switch cell, which nevertheless ideally fulfills the desired switching characteristics for such cells:
  • the vacuum switch cell is opened quickly by means of the energy store and closed in a curve-controlled manner.
  • a further advantage lies in the simple mechanical end position limitation, which is provided only once in the single gearbox and which prevents the selector contacts from advancing beyond the permissible switching range. Corresponding necessary end position limits are no longer required on the respective phase plates.
  • the tap changer according to the invention is enclosed by an oil-tight housing 1, the front, removable front 4 of which is open here.
  • three phase plates 5 - one for each phase to be switched - are provided.
  • On the right side of each phase plate 5 are the circularly arranged fixed selector contacts 6, which can be connected by a rotatable, centrally arranged movable contact carrier 7 on which there are two movable selector contacts 7.1, 7.2.
  • Both movable selector contacts 7.1, 7.2 are arranged isolated from each other on the contact carrier 7 and are moved together by its rotation. Furthermore, on this side there are fixed preselector contacts 8, which can be connected by a movable contact carrier 9 on which there is a movable preselector contact 9.1. Furthermore, on this side there are the fixed by-pass contacts 10, which can be connected by a further contact carrier 11 on which there are two by-pass contacts 11.1, 11.2. Both movable by-pass contacts 11.1, 11.2 are electrically connected to one another.
  • the vacuum switch cell 12 On the left side of the phase plate 5 is the vacuum switch cell 12 with the corresponding actuating mechanism, which will be discussed in more detail below becomes.
  • three horizontal insulating shafts 13, 14, 15 lead through the entire housing 1. They penetrate all three phase plates 5, in which holes 16, 17, 18 are provided for this purpose.
  • the first insulating shaft 13 is guided through the bore 16 of the phase plate 5 and is connected to the contact carrier 7 and thus the movable selector contacts 7.1, 7.2 of each phase.
  • the second insulating shaft 14, which is partially covered in FIG. 1, is guided through the bore 17 of the phase plate 5 and is connected to the contact carrier 9 and thus to the movable preselector contact 9.1 of each phase.
  • the third insulating shaft 15 is guided through the bore 18 of each phase plate 5 and is connected to the contact carrier 11 and thus to the movable by-pass contacts 11.1, 11.2 and the corresponding vacuum switching cell 12 of each phase.
  • the first insulating shaft 13 thus actuates the movable selector contacts 7.1, 7.2 of each phase, which connect the associated fixed selector contacts 6.
  • the second insulating shaft 14 actuates the movable preselector contact 9.1 of each phase, which connects the associated fixed preselector contacts 8.
  • the third insulating shaft 15 finally actuates the movable by-pass contacts 11.1, 11.2 of each phase, which connect the fixed by-pass contacts 10, and the respective vacuum switching cell 12 of each phase.
  • the insulating shafts 13, 14, 15 in turn are made from the only one arranged on the left in FIG. 1 Maltese drive and the other components arranged on the transmission plate 2 are operated together.
  • gear plate all three insulating shafts 13, 14, 15 are rotatably supported independently of one another and spatially separated.
  • a drive shaft 19 leads from a drive (not shown in more detail) into the housing 1 from below.
  • a first gear wheel 20 which corresponds to a second gear wheel 21 which is perpendicular thereto.
  • This second gear wheel 21 is mounted in a bearing 22 in the gear plate 2 and is firmly connected to a Maltese driver 23, which has a roller 24 at its end.
  • a third gear wheel 25 which in turn is also mounted in a further bearing 51 in the gear plate 2.
  • a rocker arm 26 is attached, which leads to a rotatably articulated lever 27, the other free end of which is in turn rotatably articulated to a further rocker arm 28, which is attached to the insulating shaft 15.
  • a thrust crank mechanism known per se is thus realized.
  • a Geneva wheel 29 is fastened in such a way that the cutouts of the Geneva wheel 29 interact with the roller 24 of the Geneva driver 23.
  • a single actuating roller 30 is also provided, which engages in a certain position of the Geneva wheel 29 in a pivotable lever 31 which is connected to the insulating shaft 14.
  • This drive works as follows: When the tap changer is actuated, the drive shaft 19 rotates, this rotation is transmitted to the second gear wheel 21 via the first gear wheel 20. As a result, the Maltese driver 23 rotates, its roller 24 engages in the Maltese wheel 29, rotates it by a certain angle, which depends on the dimensioning of this Maltese wheel 29 and the incisions located thereon, and thus also rotates the insulating shaft 13 connected thereto by one Switching step.
  • the dimensioning mentioned is designed so that all the fixed selector contacts 6 are swept when the Geneva wheel 29 is rotated completely. With each switching, the movable selector contacts 7.1, 7.2 of each phase are switched from one fixed selector contact to the other, adjacent selector contact - depending on the direction of rotation.
  • the rotary movement is transmitted to the third gear wheel 25 and thus to the rocker 26.
  • the gear wheels are dimensioned such that the third gear wheel 25 rotates by 180 degrees with each changeover.
  • the rocker arm 26 rotates, the further rocker arm 28 and thus the insulating shaft 15 are rotated through the lever 27 by a certain angle and then back again into the starting position.
  • the movable by-pass contacts 11.1, 11.2 of each phase are briefly deflected from the end position and opened and then moved back into the end position.
  • the isolating shaft 15 While the isolating shaft 13 rotates through a certain angle in the same direction in each circuit and can therefore make complete rotations, the isolating shaft 15 always rotates alternately to the left or right by an angle and back again and transmits this movement to the oscillating movable by-pass contacts 11.1, 11.2 swiveling out of the middle position into an end position and back again. Due to the roller 30 arranged on the Geneva wheel 29, which engages in a certain position in a cutout of the lever 31, this is then pivoted through a certain angle and with it the insulating shaft 14, which actuates the movable preselector contact 9.1 of each phase. The selection is only activated after a complete rotation of the Geneva wheel 29 and thus after all fixed selector contacts 6 have been run through.
  • the Geneva wheel 29 can rotate completely once, running through all the fixed selector contacts 6 without the selection being activated, then this is actuated and all the fixed selector contacts 6 can be run through again in the same direction of rotation with the selection selected. Similarly, the selection is switched back after a complete rotation in another direction.
  • FIG. 3 shows once again the arrangement of the different fixed and movable contacts explained on the respective phase plate 5 and their actuation by the insulating shafts 13, 14, 15.
  • the movable selector contacts 7.1, 7.2 which are insulated from one another, are dimensioned such that they can both contact two adjacent fixed selector contacts 6, or can rest completely on only one such contact, as is necessary to implement the switchover sequence shown in FIG. 7.
  • the movable preselector contact 9.1 switches after one revolution of the Maltese wheels 29 from one position to the other and thus switches part of one Winding up or down or deflecting this depends on whether the selection is in the respective circuit of the step transformer as a known coarse selector or well-known turner works. Result for the tap changer according to the invention there are no differences in the construction.
  • the movable, electrically interconnected by-pass contacts 11.1, 11.2 bridge both fixed contacts 10 in the stationary state and, when switched, rest on only one of these fixed contacts 10.
  • the contact derivation from the movable, rotatable contacts 7.1, 7.2; 9.1; 11.1, 11.2 is carried out by concentric slip rings 32, 33, 34.
  • Two slip rings 32, insulated from one another, are provided for the contact derivation of the two movable selector contacts 7.1, 7.2, which lie congruently one above the other in FIG. 3, so that only the upper one of them you can see.
  • FIG. 4 shows the elements arranged on the other side of the respective phase plate 5 without insulating shafts, and in FIG. 5 the elements for actuating the respective vacuum switching cell 12 are shown again, which will be explained in more detail below.
  • a console 35 is attached to each phase plate 5 and supports the vacuum switch cell 12.
  • the actuating mechanism consists of a control disk 36 which is connected to the insulating shaft 15 and a two-armed lever 37 which is rotatably mounted on the bracket 35 and has a roller 38 at one free end and the other free end of the vacuum switchgear cell 12, more precisely its actuating plunger 45, works.
  • the roller 38 corresponds to a control cam 39 on the control disk 36.
  • a release contour 40 which is dimensioned such that it deflects a pawl 41 in certain positions of the control disk 36.
  • This triggering contour 40 can be realized in a particularly advantageous manner by means of two individual triggering cams. The lever 37 is then released by the deflected pawl 41, which is otherwise blocked by the non-deflected pawl 41.
  • a spring 42 is supported on the bracket 35 and presses the roller 38 of the lever 37 against the cam 39.
  • Another spring 43 presses the pawl 41 against the lever 37 and blocks it in the normal state.
  • a third spring 44 on the actuating plunger 45 increases the contact pressure in the stationary state and is not in itself necessary for actuation.
  • the lever 37 is suddenly released and also opens the vacuum switching cell 12 suddenly with the spring 42.
  • the insulating shaft 15 then rotates and with it the control disk 36 back again.
  • the roller 38 runs on the cam 39 and closes the vacuum switching cell 12 continuously.
  • the pawl 41 engages again on the lever 37 and blocks it; the end position and the starting position for the next changeover have been reached.
  • the mode of action is as follows:
  • the Geneva wheel 29 can initially rotate in each direction by one turn until the driver 50 meets the driver 48, with the further rotation in the same direction the blocking disk 46 is also rotated. If this has rotated by one turn, the driver 47 hits the stop 49 and blocks both the blocking disk 46 and the Geneva wheel 29, which then has undergone two turns - the end position has been reached.
  • the process is repeated analogously - the floating blocking disk 46 allows two revolutions of the Geneva wheel 29 in both directions, during which all fixed selector contacts 6 are swept twice - once with and once without an activated selection.
  • driver 50 If there is only one driver 50, this can be of any shape or size be dimensioned. This makes it possible to easily End position limitation to the permissible revolutions defined above, which are not quite correspond to a full rotation of 360 degrees, but in each case of the two Switching steps corresponding angles are missing to adjust.
