Definitions
- the present invention relates to a tap changer for uninterrupted switching between at least two winding taps of a
- An object of the present invention is to propose a tap changer of the type mentioned above with high surge voltage resistance, also referred to as aO strength.
- the delayed in each switching direction switching or triggering of at least one mechanical switching element can be realized in the tap changer that the at least one switching means and its associated
- Cam is firmly anchored to the housing and decouples the rotational movements of the shift shaft and mounted on this cam from each other.
- Fig. 1 shows a schematic perspective view of an embodiment of a tap changer according to the invention with a freewheeling element, consisting of a switching shaft arranged thereon with actuating elements and switching elements coupled thereto.
- Fig. 2 shows a detail of a detail in a schematic detail
- Fig. 3 shows a schematic plan view of the tap changer according to FIG. 1 from below.
- FIGS. 1 to 3 shows a flowchart to illustrate the switching sequences of an exemplary embodiment of the tap-changer according to the invention according to FIGS. 1 to 3 during a switching cycle in respectively different switching directions.
- Fig. 5 shows in several circuit diagrams, the individual, successive switching states of the various components of the tap changer in a first switching direction.
- Fig. 6 shows in several circuit diagrams, the individual, successive switching states of the various components of the tap changer in a first switching direction.
- FIG. 7 shows, with reference to a further circuit diagram, a variant of a tap changer supplemented by two additional permanent main contacts.
- the embodiment described below is not intended to be limiting, but serves to explain the function and the switching options of a tap changer according to the invention.
- FIGS. 1 and 2 show an embodiment of a tap changer 10, comprising a switching shaft 22 with arranged thereon actuating elements 24 and coupled thereto
- FIG. 3 also shows a plan view of the tap changer 10 according to FIG. 1 from below.
- a downstream switching or tripping time has one of two mechanical
- Switching TTF a defined time interval to the other switching or Tripping times of a first mechanical switching element MTF and two vacuum interrupters MSV and TTV on.
- nachverlagerten switching or tripping time point having mechanical
- the tap changer 10 provides a switching shaft 22 which is rotatable about its axis in both directions and which has four disc-shaped four arranged in parallel
- Switching elements 26 and vacuum interrupters in the switching block 27 by zooming into the outline of the switching block 27 and are rotated past it, where they rotate or actuate the respective mechanical switching element and / or the respective vacuum interrupter to a defined switching path.
- each of the four existing cams 28 can be at their
- Each outer circumference each have a plurality of equally spaced projections or cams 30, so that for a complete switching cycle of the
- This freewheeling element 34 is designed as a circular segment-shaped, for switching shaft 22 concentrically arranged guide slot 36 for an annular
- FIG. 4 shows an exemplary and qualitatively to be understood flow chart to illustrate the switching sequences of an embodiment of the tap changer 10 according to the invention (see Figures 1 to 3) during a
- the upper diagram illustrates the switching sequence of a total of four individual switching units tap changer in a first switching direction, while the lower
- FIG. 5 Figures 5a to 5h show in total nine Schematics the individual, successive switching states of the various components of the tap changer in a first switching direction, which is characterized in Fig. 5a by the switching direction n - n + 1.
- downstream mechanical switching element TTF all other switching elements and vacuum tubes.
- the switching position of the tap changer 10 for the start of switching is illustrated in Fig. 5a.
- the first vacuum interrupter MSV is in this case closed, while the switching contact of the second vacuum interrupter TTV is open.
- the first mechanical switching element MTF is in a first switching position, in which the load current I L from the first winding tap 12 of the tapped transformer 16 via the first mechanical switching element MTF and the first closed
- Vacuum switch tube MSV (Fig. 5e, Fig. 5f) and the subsequent opening of the second vacuum interrupter TTV (Fig. 5f, Fig. 5g) is prepared.
- the load current I L flows in the manner shown in Fig. 5g from the second winding tapping 14 of the tapped transformer 16 through the correspondingly connected first mechanical switching element MTF and the closed first vacuum interrupter MSV to
- FIG. 6 show in several circuit diagrams the individual, successive switching states of the various components of the
- Step switch in a second switching direction shows the operations in a complete downshift, for a drive direction from right to left (n + 1 -> n), ie starting at a time corresponding to the lower scale and ending at the very left at zero.
- the switching position of the tap changer 10 at the start of switching within a first period is illustrated in FIG. 6a.
- the first vacuum interrupter MSV is in this case closed, while the switching contact of the second vacuum interrupter TTV is open.
- the first mechanical switching element MTF is in its second switching position, in which the load current I L from the second winding tap 14 of the tapped transformer 6 via the first mechanical switching element MTF and the closed first vacuum interrupter MSV for load discharge LA can flow. This is also the switching position corresponding to FIG. 5h, with which the first switching cycle was completed according to the upper diagram of FIG.
- This opening of the first vacuum interrupter MSV takes place within a definable period of time after the start of the shift, which is shown in FIG. 6b (opening) and in FIG Fig. 6c (MSV open) is illustrated.
- this switching state of the tap changer 10 with the opened first vacuum interrupter MSV and the closed second vacuum interrupter TTV and in the second switching position of the second mechanical switching element TTF shown in Figures 6a to 6f of Laststom l L flows in the manner shown in Figures 6c and 6d from the first winding tapping 12 of the tapped transformer 16 through the second load branch or second path 20, which can also be referred to as a resistance branch or R branch, for the load discharge LA.
