Definitions

  • the present invention relates to an energy accumulator for actuating a switching device, which energy accumulator includes a chargeable mechanical spring means, tensioning means for charging the spring means, actuating means for actuating the switching device and release means for discharging the spring means.
  • the invention also relates to a tap changer and to a transformer.
  • a tap changer is commonly used in connection with a transformer in order to vary the transformation rate thereof.
  • one of the windings in the transformer has a fixed amount of turns connected to the circuit.
  • the other winding has one fixed connection point, whereas the other connection point can be selected among a number of points to attain a required voltage.
  • the selectable points may be located after each other along a portion of the winding corresponding to 70% to 100% of its full extension.
  • Tap changing includes a plurality of manoeuvres including the opening and closing of switches e.g. via a spring loaded energy accumulator and moving a selector arm to a new connection point.
  • the present invention is related to the energy accumulator for the actuation of the switches.
  • Closing and opening of the switches have to be performed very rapidly with a considerable force.
  • the time duration is in the order of 10 ms. It is therefore common that the actuation movement is driven by the release of a spring that has been charged with mechanical energy, whereby the spring can provide the necessary force and act rapidly.
  • the supply of the energy, i.e. the charging of the spring can be made during a much longer period and thus at a much lower power.
  • the advantages gained by using a spring loaded energy accumulator are thus evident, and this kind of actuation of the switches in an on load tap changer therefore is commonly used.
  • the energy accumulators according to prior art are generally complicated and includes a large part of components that are to move and to cooperate for receiving the energy at a low speed, store the energy and deliver the energy at high speed.
  • the object of the present invention is to improve an energy accumulator of the kind in question, in particular to attain an energy accumulator that is simple and reliable and overcomes the drawbacks entailing known energy accumulators of this kind.
  • the invention is primarily intended for the actuation of switches in a diverter switch of an on load tap changer, but is not exclusively related to such an application.
  • an energy accumulator of the kind specified in the introduction of this application includes the specific features that the tensioning means includes a first linearly movable body having drive means connectable to a driving source for applying a tensioning stroke to the first movable body, and having first spring support means, the actuating means includes a second linearly movable body having cam profile means and having second spring support means, and further includes cam follower means arranged to cooperate with the cam profile means and which cam follower means has connection means to the switching device, the release means includes a latching mechanism arranged to lock the second movable body and to be brought to an unlocking position upon influence from the first movable body, and which energy accumulator further includes guiding means arranged to guide the first and second movable body in a respective linear movement, which linear movements are in parallel to each other, and in that the spring means is arranged between said first and second spring support means.
  • This general construction of the energy accumulator requires very few moving parts, results in a short mechanical transmission path for transferring the actuation power from its input to its output, and thereby can be made relatively compact.
  • the low number of active components, the linear movement both for charging and discharging the spring means and the short transmission path makes the device very simple. This reduces the manufacturing and assembly costs, and leads to reduced need for maintenance and to a safe functionality at operation.
  • the cam profile means includes a plurality of cam profiles arranged in parallel to each other and, the cam follower means includes a corresponding plurality of cam followers cooperating with a respective cam profile and being connectable to a respective switch of the switching device.
  • the second movable body has a first side on which said cam profile means is located and an opposite side on which said second spring support means is located, and in that the second movable body is made of an insulating material.
  • This very important embodiment of the invention provides an effective electricity barrier between separate parts of the energy accumulator.
  • the first side of the second movable body is facing toward the switching device and the opposite side is facing toward the spring means, the first movable body and said drive means.
  • the components connected to the drive source and related to the charging of the spring means may be at ground potential. According to this embodiment these components by the barrier formed by the second movable body will be electrically insulated from the switches and those components that are directly engaged in the actuation of these. The result is that the components on both sides of this barrier can be arranged at a relatively short distance from each other, which further contributes to a compact construction.
  • the spring means includes at least one spring device having a plurality of springs arranged in series to each other, and which springs have different spring characteristics.
  • the force/time relation of the spring means can be tailored to be optimized in accordance with the required patter. Normally two springs arranged in series in a spring device will be appropriate.
  • the spring means includes a plurality of spring devices arranged in parallel to each other.
  • the number of spring devices is two.
  • the guiding means includes a plurality of first guide bars for the first movable body and a plurality of second guide bars for the second movable body, which rods all are arranged in parallel to each other.
  • each spring device includes at least one helical spring arranged coaxially around a respective bar of the first guide bars.
  • This type of springs is particularly adapted for the linear movement pattern of the invented energy accumulator. By arranging the springs around the guide bars, the springs will be directionally stabilized in alignment with the moving of the bodies.
  • the latching mechanism includes a pawl arranged to contact the second movable body and thereby prevent linear movement thereof, and whereby the first movable body during an end phase of its tensioning stroke is arranged to contact the pawl for actuating the pawl to release its contact with the second movable body.
  • the drive connection means includes a groove on the first movable body, which groove is arranged to cooperate with a roller of a crank arm from the drive source such that a 180° rotation of the crank arm provides one tensioning stroke of the first movable body.
  • each cam follower includes a cam roller arranged to be in contact with a respective cam profile and a rocking lever having a first end on which the cam roller is mounted and a second end connectable to an actuating rod of a switch, which level has a first portion and a second portion forming an obtuse angle with the first portion, and which level is provided with a spring pressing the cam roller into contact with the cam profile.
  • the rolling contact reduce losses and wear due to friction, and by the angled lever the transmission of the movement to an actuating rod of the switch that is perpendicular to the movement of the cam profile.
  • the obtuse angle is within the range of 145° to 165°.
  • the invented tap changer includes an energy accumulator according to the present invention, in particular a according to any of the preferred embodiments thereof.
  • the invented transformer includes a tap changer according to the present invention.
  • the invented tap changer and the invented transformer gain from the advantages of the invented energy ackumulator and the preferred embodiments thereof, and which advantages have been described above.
  • Fig. 1 schematically illustrates an on load tap changer 100 of a kind for which the energy accumulator according to the present invention is intended.
  • the tap changer 100 is connected to a regulating winding 105 of a transformer and has a set of different taps 110.
  • the tap changer of Fig. 1 is of diverter switch type, and comprises a diverter switch 115 and a tap selector 120.
  • the tap selector 120 of Fig. 1 comprises two current collectors 125, two selector arms forming two moveable contacts 130 and further comprises a set of fixed contacts 135, where, each fixed contact 135 is arranged to be connected to one of the taps 110 of the regulating winding.
  • the tap changer 100 of Fig. 1 has fifteen different fixed contacts 135, and the regulating winding 105 has fifteen taps 110.
  • the tap changer 100 of Fig. 1 is mechanically linear in the sense that the current collectors 125 are implemented as linear rods, and the fixed contacts 135 are arranged in a linear fashion.
  • the two current collectors 125 together form a current collector part.
  • the diverter switch 115 comprises two series connections of a main contact 140 and a transition contact 145, with transition resistor 150 connected in parallel with transition contact 145. It is common that the contacts are vacuum interrupters. Each of the series connections are, at one end, connected to a respective one of the two current collectors 125, and, at the other end, connected to an external contact 155 of the tap changer 100.
  • the movable contacts 130 are, at one end, in electrical contact with a respective one of the current collectors 125.
  • a selector arm 130 can move along the current collector 125 to which it is connected, in order to reach different positions, at which the other end of the movable contact 130 is in electrical contact with one of the fixed contacts 135.
  • the moveable contacts 130 could for example be sliding contacts arranged to slide along the current collectors 125, to allow for electrical connection between the current collectors 125 and the different fixed contacts 135.
  • the driving of the moveable contacts 130 of Fig. 1 is arranged so that if one of the moveable contacts 130 is in contact with a fixed contact 135, connected to a first tap, the other moveable contact 130 is in contact with a fixed contact 135, connected to a tap 110 which is adjacent to the first tap 110.
  • one or the other of the moveable contacts 130 will be in electrical contact with the external contact 155, and thus provide an electrical path through the tap changer 100.
  • the two current collectors 125 will take turns at being part of the electrical path of the tap changer 100.
  • the electrical path through the tap changer 100 ends at the external contact 155 at one end, and at the fixed contact 135 that is currently connected at the other end.
  • An example of a diverter switch 115 is described in EP0116748 .
  • the diverter switch 115 of Fig. 1 is an example only, and any suitable type of diverter switch 115 can be used.

  • the other end of the regulating winding 105 is provided with an external contact 165.
  • the electrical path between the external contacts 155 and 165 will include a different number of the regulating winding turns.
  • the regulating winding 105 is often not seen as part of the tap changer 100, and has therefore been surrounded by a solid line in Fig. 1 .
  • the vacuum interrupters of the contacts 140 and 145 and those on the other current collector are to be closed and opened, respectively in a and certain sequence. This allows the selector arms with the movable contacts 130 to move to come into contact with the adjacent one of the fixed contacts 135. Closing and opening of the vacuum interrupters in the diverter switch 115 and movement of the movable contacts in the tap selector 170 has to be made in a certain time relation to each other.
  • the actuation of the vacuum interrupters requires a rapid and strong actuation force, that normally is obtained by an energy accumulator having a spring that can be charged and discharged.
  • the energy accumulator according to the present invention has the function to provide actuation of the switches in the diverter switch.

  • Each spring device 5 is composed by two helical springs 51, 52 arranged coaxially around one of the guide bars 71 of the tensioning slide 3, of which one is as strong spring 51, and the other a weak spring 52.
  • the springs 51, 52 of one spring device 5 thus have different spring characteristic.
  • Each spring device 5 at one end is supported by a first spring support means 32 connected to the tensioning slide 3 and by second support means (not visible in the figure) connected to the cam slide 4.
