Definitions

  • the invention relates to an on-load tap changer based on the resistance principle.
  • On-load tap changers based on the resistance principle are basically based on two alternative basic principles. Either as a so-called load selector or as a load changeover switch with a selector.
  • the documents DE 10 2013 107 545 A1 and DE 10 2013 107552 A1 each describe a load selector that selects the desired new tap contact and switches from the currently live, old tap contact to the new tap contact in one go under load.
  • the diverter switch insert that carries out the changeover and to which the vacuum interrupters, the moving contacts and the resistors are attached is rotatably arranged in a closed oil tank.
  • DE 25 29 381 C3 describes an on-load tap changer in which first the selection without load is carried out relatively slowly by a selector and then the switching is carried out as quickly as possible under load by a diverter switch.
  • the selector and diverter switch are two spatially separate structural units.
  • the diverter switch with its switching resistors and switching contacts is housed in a separate and sealed oil compartment.
  • the selector which consists of a construction of insulating bars held by two cage rings, is located below the diverter switch in the transformer housing.
  • DE 199 57 013 C1 also discloses an on-load tap changer having a diverter switch and a selector.
  • the diverter switch and selector are each driven by their own shaft. Two shaft ends of the two shafts are aligned in a one-way clutch.
  • EP 1 215 694 A2 discloses a switch monitor for a tap changer mounted on a bearing plate.
  • the tap changer has a diverter switch, which is operated by means of an energy store and an output shaft.
  • EN 20 2012 101475U1 also discloses an on-load tap changer.
  • Both the load selector and the diverter switch with selector function according to the high-speed resistance switching principle, according to which the circulating current that flows during switching while the old and new tap contact are simultaneously being contacted is limited by being routed through ohmic resistors.
  • the on-load tap-changer is inexpensive to produce, easy to assemble and safe to operate.
  • the diverter switch is mounted with all its parts on the diverter switch base plate and the selector with all its parts on the selector base plate.
  • the drive shaft actuates and/or drives the diverter switch and selector together. Due to the particularly simple structure, it is possible to variably arrange both the selector and the diverter switch of one phase, as well as the respective phases among themselves, at a distance from one another, depending on the voltage requirements.
  • the selector base plate and the diverter switch base plate can be designed in any way as required, for example from an insulating material such as plastic or fiber-reinforced plastic, in particular a mixture of polyamide or polyphthalamide with glass fibers.
  • the diverter switch base plate is preferably arranged parallel to the selector base plate.
  • the drive shaft can be designed in any way as required, for example in such a way that it is made up of one piece or of several parts.
  • the on-load tap changer can have a preselector, which is also actuated and/or driven by the common drive shaft.
  • the preselection serves to to add a control winding in the same direction or in the opposite direction to a main winding.
  • the preselector can be arranged on the selector base plate, the on-load tap changer base plate or a separate preselector base plate.
  • the drive shaft can be driven directly by an electric motor.
  • a spring energy store or an intermediate gear can be arranged between the electric motor and the drive shaft.
  • At least one additional rod or, alternatively or in addition to the rods, at least one spacer and/or at least one plate can be used.
  • the connection can also be realized by means of spacers which are sprayed onto the selector base plate and/or the diverter switch base plate.
  • the arrangement of the individual parts, in particular vacuum interrupter, resistor and switching element, can be distributed to the first and/or the second side of the diverter switch base plate, depending on the requirements.
  • the vacuum interrupter and the switching element can also be actuated directly or via gear wheels, Geneva wheels or connecting rods.
  • the further selectors are preferably designed like the selector and/or the two further diverter switches like the diverter switch.
  • Each preselector base plate is preferably arranged parallel to the respective selector base plate and/or the respective diverter switch base plate.
  • At least one additional rod or, alternatively or in addition to the rods, at least one spacer and/or at least one plate can be used.
  • the connection can also be realized by means of spacers sprayed onto the selector base plates and/or the diverter switch base plates and/or the preselector base plates.
  • FIG. 1 a first embodiment of an on-load tap changer 1 according to the resistance principle is shown schematically.
  • the on-load tap changer 1 has three selectors 20 and three diverter switches 40 here.
  • Each selector 20 and each diverter switch 40 is associated with a particular phase of a tapped transformer (not shown).
  • a single-phase variant of the on-load tap changer 1 according to the invention would therefore have only one diverter switch 40 and only one selector 20 .
  • Each selector 20 is mounted on a selector base 21 and each diverter switch 40 is mounted on a diverter switch base 41 .
  • the individual plates 21, 41 are pushed onto at least one rod 15 and are held by it.
  • the individual plates 21, 41 can also be fastened in other ways, for example using spacers, sprayed-on webs or other plates.
  • a common drive shaft 10 drives all selectors 20 and diverter switches 40.
  • the drive shaft 10 extends through the individual plates 21, 41 to actuate the selectors 20 and the diverter switches 40.
  • the drive shaft 10 is preferably actuated by a motor 13 via a bevel gear 12 .
  • the drive shaft 10 can also be designed so that it can be actuated directly by a motor 13 .
  • the selectors 20 and the diverter switches 40 are operated by the common drive shaft 10 in such a way that a diverter switch is carried out from one tap to an adjacent tap.
  • the drive shaft 10 can consist of one or more be trained parts.
  • the selector base plate 21 is preferably made of an insulating material such as plastic or fiber-reinforced plastic (eg a mixture of polyamide or polyphthalamide with glass fibers).
  • the selector base plate 21 has a first side 22 and a second, opposite side 32 .
  • a plurality of fixed contacts 18 are arranged on the first side 22 and are connected via lines 19 to winding taps of a control winding of the step transformer.
  • the fixed contacts 18 extend from the first side 22 through the selector base plate 21 to the second side 32.
  • the fixed contacts 18 are preferably made of copper and are additionally silver-plated.
  • a first Geneva wheel 25 with a first, movably mounted moving contact 23 is attached to the first side 22 .
  • the first Geneva wheel 25 is rotatably mounted on a first bearing axle 26 about an axle 11 .
  • the bearing axle 26 is designed as a separate part that is mechanically connected to the selector base plate 21 .
  • the bearing axle 26 can also be sprayed on during the production of the selector base plate 21 and can be formed with it as a unit.
  • a first driver 27 is arranged next to the first Geneva wheel 25 and is actuated via the drive shaft 10 which extends through the selector base plate 20 .
  • the first driver 27 has a first cam 28 which engages in the first Geneva wheel 25 and rotates it in the process.
  • the first driver 27 When the selector 20 is actuated, the first driver 27 is rotated through 360°. When interacting with the first Geneva wheel 25, when the first driver 27 rotates completely, the first Geneva wheel 25 is rotated only piecemeal, ie by a fraction of a complete rotation. The combination of the first driver 27 and the first Geneva wheel 25 converts the continuous rotational movement of the first driver 27 into a step-by-step or piecemeal rotation of the first Geneva wheel 25 . The combination of a Geneva wheel and a driver allows both parts to be locked against each other even when the dial is at rest, i.e. before or after the selector is operated.
  • the first moving contact 23 Before the first Geneva wheel 25 is actuated, the first moving contact 23 always makes contact with one of the fixed contacts 18 and connects it in an electrically conductive manner to a connection 29 of a first branch of the diverter switch 40.
  • the selector 20 When the selector 20 is actuated, the first Geneva wheel 25 is rotated and the first moving contact is thereby rotated 23 switched from this fixed contact 18 to an adjacent fixed contact 18.
  • Each fixed contact 18 is contacted on the first side 22 at a first contact area 24 via the first moving contact 23.
  • FIG. 3 the second side 32 of the selector 20 is shown.
  • the fixed contacts 18 are connected via lines 19 to winding taps of the control winding of the step transformer.
  • a second Geneva wheel 35 with a second moving contact 33 is attached to the second side 32 .
  • the second Geneva wheel 35 is also mounted on a second bearing axle 36 so as to be rotatable about the axle 11 .
  • a second driver 37 is positioned adjacent the second Geneva wheel 35 and is actuated by the same drive shaft 10 as the first driver 27 .
  • the second driver 37 has a second cam 38 which engages in the second Geneva wheel 35 and rotates it in the process.
  • the first cam 28 is arranged offset to the second cam 38 or the drivers 27, 37 and thus the cams 28, 38 are arranged offset.
  • the offset arrangement of the cams 28, 38 or drivers 27, 37 causes the Geneva wheels 25, 35 and thus the moving contacts 23, 33 to be actuated at a different time.
  • the second moving contact 33 Before the second Geneva wheel 35 is actuated, the second moving contact 33 always makes contact with one of the fixed contacts 18 and connects it in an electrically conductive manner to a connection 39 of a second branch of the diverter switch 40.
  • the selector 20 When the selector 20 is actuated, the second Geneva wheel 35 is rotated and the second moving contact is thereby rotated 33 switched from this fixed contact 18 to an adjacent fixed contact 18.
  • the moving contacts 23, 33 make contact with the same fixed contact 18. However, this can vary depending on the circuit.
  • Each fixed contact 18 is contacted on the second side 32 in a second contact area 34 via the second moving contact 33.
  • the diverter switch base plate 41 is preferably made of an insulating material such as plastic or fiber reinforced plastic (eg a mixture of polyamide or polyphthalamide with glass fibers) and has a first side 42 and a second, opposite side 52 .
  • a vacuum interrupter 43 is arranged on the first side 42 and is fastened to the diverter switch base plate 41 by means of holders 44 .
  • the vacuum interrupter 43 includes a fixed contact 45 and a moving contact 46, via which the vacuum interrupter 43 is opened or closed.
  • a cam disk 47 is also mounted on the first side 42 .
  • a rocker arm 48 is rotatably mounted between the cam disk 47 and the moving contact 46 in such a way that when the cam disk 47 rotates, one end 50 of the rocker arm 48 follows a contour 49 of the cam disk 47 and thereby actuates the vacuum interrupter 43, i.e. closes or opens it via its moving contact 46 .
  • the moving contact 46 is guided in a holder when it is actuated.
  • FIG. 6 the second side 52 of the diverter switch 40 is shown.
  • a resistor 53 is arranged on the second side 52 .
  • a first gear wheel 54 which corresponds to the cam disk 47 on the first side 42, is rotatably mounted on the second side 52.
  • the drive shaft 10 passes through the cam disc 47, the diverter switch base plate 41 and the first gear wheel 54 and drives the cam disc 47 and the first gear wheel 54.
  • a switching element 55 which is driven via a combination of a second gear wheel 56 and a connecting rod 57, is attached to the second side 52.
  • the switching element 55 is actuated via the individual gears 54, 56 and the connecting rod 57.
  • the rotational movement of the drive shaft 10 is converted into a linear movement of the switching element 55.
  • the switching element 55 is designed as a bridging switch.
  • the switching element 55 can also be designed as a rotary switch.
  • the arrangement of the individual parts, in particular the vacuum interrupter, the resistor and the switching element, can be distributed to the first and/or the second side of the diverter switch base plate, depending on the requirement.
  • the vacuum interrupter and the switching element can also be actuated via gear wheels, Geneva wheels, connecting rods.
  • FIG. 7 are the selector 20 and the selector base plate 21 of FIG. 2 and 3 and the diverter switch 40 and the diverter switch base plate 41 of FIG FIG. 5 and 6 , associated with a phase, shown in assembled condition.
  • the selector base plate 21 is connected to the diverter switch base plate 41 via two rods 15 .
  • the drive shaft 10 runs through the drivers 27, 37, the cam disc 47 and the two base plates 21, 41.
  • FIG. 8th a second embodiment of the on-load tap changer 1 is shown schematically.
  • the on-load tap changer 1 has a preselector 60 for each phase, which is also actuated by the common drive shaft 10 .
  • the preselector 60 is used to add a control winding of the respective phase in the same direction or in the opposite direction to a corresponding main winding.
  • Each selection 60 is on mounted on a separate preselector base plate 61, but can also be mounted on the selector base plate 21 or the on-load tap changer base plate 41 of the respective phase as required.
  • the preselector 60 can be actuated directly via the drive shaft 10 or indirectly, for example via a gear.
