Definitions

  • the invention relates to a method for uninterrupted switching with semiconductor switching elements between winding taps of a tapped transformer.
  • Such a method using semiconductor switching elements is known from the WO 01/22447 known.
  • the method described there works both with electrical switching means, the IGBTs, as well as mechanical contacts. It is designed so that the actual load switching in the zero crossing of the load current with two IGBT's with diodes in Griserscnies. Necessary part of this known method is the detection and detection of the respective current zero crossing as a prerequisite for the initiation of load switching at this time.
  • This method requires a specific adaptation of the tap changer to the respective tap transformer, which is to be connected.
  • tapped transformer and tap changer are coordinated and act together electrically.
  • This known method is therefore not suitable for use in a separate, universally applicable, not tailored to a specific transformer tap changer.
  • WO97 / 05536 discloses a method for uninterrupted switching between winding taps of a tapped transformer having two load branches, each of the two load branches including a series arrangement of two oppositely connected IGBTs, and with a diode connected in parallel with each IGBT.
  • the object of the invention is to provide a method of the type mentioned above, which is simple in construction, has a high functionality and in which it is not necessary to have to switch only exactly at the zero crossing of the load current.
  • Another object of the invention is to provide a corresponding method which in each case, i. H. without coordination to the concrete tapped transformer, which is to be wired, is functional.
  • the inventive method is based on the general inventive idea, not varistors, as known from the prior art for a long time to use as components for overvoltage protection, but for commutation of the load current of the tap changer from one side to the other, ie from the previously switched Winding tap on the newly connected winding tap to use by appropriate process steps.
  • the particularly dimensioned varistors connected in parallel with each IGBT exert a new function: After commutation of the impressed load current from the line voltage from the disconnecting IGBT to the parallel-lying varistor (smaller commutation circuit), the varistor flowing through the load current builds according to its characteristics IU characteristic a voltage that shows a relatively small dependence on the instantaneous value of the current and during the switching process of the OLTC remains practically constant.
  • the varistors are dimensioned such that the varistor voltage, which results when loaded with the peak value of the maximum current, still has a sufficient safety margin to the maximum blocking voltage of the IGBTs.
  • the clamping voltage of the varistors (U Var at 1 mA) must be well above the peak value of the maximum step voltage so that the load current can commute from the disconnecting OLTC side over the step voltage to the side taking over the load current (large commutation circuit).
  • Switching off the off-switching side is done before the switch-on of the receiving side.
  • the current flow time of the load current via one of the two varistors of the disconnecting side is extended accordingly.
  • the switching-on of the receiving tap changer side takes place before the switch-off process of the switching-off side.
  • both IGBT groups are closed so that the step voltage starts to build up a circulating current during this period.
  • the di / dt of the forming circulating current depends on the instantaneous value of the step voltage in the overlapping period and on the circulating inductance of the circulating current.
  • the circulation current is added to the load current on the switch-off side and leads to a gradual increase of the total current to be commented out ( I L ( t ) + I C ( t )) until the moment of the switch-off process . This leads to an increase in the commutation loss energy occurring at the disconnecting side and to an extension of the commutation process.
  • FIG. 1 shows a schematic flowchart of a first method according to the invention.
  • the method assumes that in a tap changer in which is to be switched from a previous winding tap of a tapped transformer to a new Windungsanzapfung, two load branches are provided, via a mechanical switch DS a , DS b and a series arranged in series two oppositely connected IGBTs I an , I ap ; I bn , I bp , each with a parallel diode d an , d ap ; d bn , d bp can be electrically connected to a common load dissipation and that parallel to each of said IGBT's a varistor V an , V ap ; V bn , V bp is switched.
  • Each of the two load branches should be able to be bridged by a permanent main contact MC a or MC b .
  • the mechanical switches DS a and DS b acting as release contacts are shot on both sides.
  • ignition voltage is applied to the gates of the IGBTs I on, I ap of the disconnecting side.
  • the IGBTs turn on I and I ap turn off the hard side.
  • the load current is now commutated to the varistors V an and V ap of the disconnecting side.
  • this load current is commutated to the IGBT's of the receiving side I bn , I bp to be connected .
  • the IGBTs I bn and I bp of the receiving side are switched to the non-conductive state.
  • the final step in the process is the opening of the mechanical contacts DS a and DS b , which protect the IGBTs from the transient voltage stresses that may be applied to the step winding.
  • FIG. 2 shows one for implementing the method according to FIG. 1 particularly suitable circuit.
  • each of the two winding taps tap n and tap n + 1 via a mechanical switch DS A and DS B counter with a series circuit of two IGBTs I and I ap on the side of n and I bn and I BC Since n + 1 connected to the tap changer lead.
  • Parallel to each IGBT is a diode d an , d ap ; d bn , d bp provided, wherein the two diodes are connected in each load branch opposite to each other.
  • V an , V ap or V bn , V bp is provided in parallel with each individual IGBT.
  • the varistors V on , V ap and V bn , V bp are dimensioned such that their varistor voltage is less than the maximum blocking voltage of the respective parallel IGBT but greater than the maximum instantaneous value of the step voltage.
  • the inventive method ie a switching sequence of, for example, tap n on tap n + 1, will be explained in more detail with reference to this circuit:
  • the load current flows through the permanent main contact MC a of tap n to tap changer lead Y.
  • the enable contacts DS a and DS b are closed.
  • these IGBTs After less than 10 ms current flow duration of I L via the IGBT group I to / I ap , these IGBTs receive a switch-off command and the IGBT group I bn / I bp simultaneously (at least in the standard case) a switch-on command.
  • the varistor is dimensioned so that the voltage of the load current-carrying varistor on the one hand below the max. Blocking voltage of the parallel IGBT, on the other hand moved above the maximum instantaneous value of the step voltage.
  • the excess of the instantaneous value of the varistor voltage over the instantaneous value of the step voltage causes the commutation of the load current with approximately constant di / dt from side A and a shift over the step voltage and the leakage inductance of the step winding L ⁇ (large commutation) with the same di / dt (in this Case positive) on the side B.
  • the varistor voltage remains constant in a first approximation.
  • the main permanent contact MC b closes and shunts the IGBT group B. Then the IGBTs I bn / I bp are switched to the non-conductive state via the gate drive.
  • the switching sequence ends with the opening of the mechanical release contacts DS a and DS b , which protect the IGBTs from the transient voltage stresses that may be effective at the tap winding.
  • FIG. 3 a modified suitable circuit for carrying out the method according to claim 1 is shown, in which the two varistors each have a side V on , V ap and V bn , V bp are combined to form a respective common varistor V a and V b .
  • the respective mechanical switch of each side DS a or DS b and the respective varistor of the associated side V a and V b also forms a series connection to the common load dissipation.
  • FIG. 4 shows a further modified inventive method, which assumes a simplification of the process and in which no mechanical switches are provided.
  • the general inventive idea to use varistors for commutation of the load current is also realized in this method.
  • each of the two load branches is a series connection of two oppositely connected IGBTs I an , I ap; I bn. I bp , to each of which a diode d an , d ap ; d bn , d bp is switched.
  • Parallel to each of the IGBTs I an , I ap; I bn. I bp is a varistor V an , V ap ; V bn , V bp switched.
  • these IGBTs receive a turn-off command, the IGBT's the turn-on side I bn and I bp a turn-on command; the IGBT's turn off the "hard” off. Subsequently, according to the invention, the load current is commutated to the varistors V an and V ap of the disconnecting side.
  • the load current is commutated to and guided by the IGBTs of the receiving side I bn and I bp .
  • this simplified method is based on a tap changer, which has no mechanical release contacts and no mechanical permanent main contacts, but in which the load current in stationary operation is guided by the IGBTs.
