Definitions

  • the invention relates to a cast resin transformer according to the preamble of claim 1.
  • From DE 198 09 572 C2 is a cast resin transformer with a low voltage winding and with a coaxially surrounding this High-voltage winding with an axial cooling channel known between two winding parts.
  • the two winding parts are connected in parallel and exist in each case from two axial part windings, each with several coils contain.
  • Each winding part consists of a radially inner Partial winding and a radially outer part of the winding, the arranged axially one behind the other and electrically connected in series are. Because the exact adjustment of the upper voltage only via winding taps on the radially outer part windings can take place, this voltage setting to the two winding parts at different voltage values instead of. Therefore, it must be done separately for them, so that for each winding part a separate tap changer is required.
  • the areas provided with the taps are the two winding parts by a partial winding with each formed a number of coils and these partial windings coaxial with those not provided with the taps Regions of the two winding parts and in the axial direction arranged one behind the other.
  • Fig. 1 shows the extending in the axial direction right outer edge 1 of a core of, for example, three core legs provided cast resin transformer.
  • the cores are each equipped with the same winding arrangement. Coaxial are guided around the core on the radially inner side a low voltage winding and on the radially outer side a high voltage winding.
  • the undervoltage winding and the high voltage winding are in the radial direction at a distance arranged one another and thus form an axial Cooling channel 2.
  • the low voltage winding consists of two in axial Direction extending, electrically connected in parallel Winding parts, each consisting of two in the axial direction successive partial windings 3.1, 3.2 and 4.1, 4.2 are formed.
  • the partial winding 3.1 of the first Winding parts spatially within the partial winding 4.1 of second winding part and the part winding 3.2 of the first Winding parts spatially outside of the partial winding 4.2 of second winding part arranged.
  • the high-voltage winding also has two in axial Direction extending, electrically connected in parallel Winding on, each two in the axial direction one behind the other lying partial windings 5.1, 5.2 and 6.1, 6.2 contain. Their spatial assignment is the same as with the low-voltage winding such that the two partial windings 5.1 and 5.2 or 6.1 and 6.2 of a winding part axially one behind the other lie and that the partial winding 5.1 of the first Winding parts concentric of the partial winding 6.1 of second winding part and the partial winding 6.2 of the second Winding parts concentric of the partial winding 5.2 of the first Winding parts are surrounded.
  • the winding parts contain the high-voltage winding additionally in each case a third sub-winding 5.3 or 6.3.
  • These partial windings 5.3 and 6.3 are on the one hand with the other partial windings 5.1 and 5.2 or 6.1 and 6.2 their winding part connected in series, on the other hand at their respective two ends by conductors 7 and 8 directly connected together so that they are directly parallel to each other are switched.
  • the connections 9 and 10 of the high voltage winding are on the one hand with one the upper ends of the Partial windings 5.1 and 6.1 connecting conductors 11 and on the other connected to the conductor 8.
  • the partial windings 5.3 and 6.3 are each, as shown in FIG. 1 shows, from several, in the example shown ten, one behind the other each coil 12 is shown in FIG. 2 provided with a tap 13; however, the coils can 12 each have a plurality of taps 13.
  • the taps 13 are opposite to the leads shown in Fig. 1 to sub-windings 5.3 and 6.3 in their circumferential direction Offset 180 ° and therefore not shown in Fig. 1.
  • the partial windings 5.3 and 6.3 are identical to each other, so that each coil 12 or tapping 13 of the partial winding 5.3 a coil 12 or tapping 13 of the partial winding 6.3 corresponds, which is at the same potential.
  • the taps 13 are connected to terminals of a switching strip 14. These contains internal connection lines 15 such that the both lying at the same potential taps 13 of the partial windings 5.3 and 6.3 are connected to each other.
  • Each with two taps at the same potential 13 connected connection line 15 is to an outer Connection of the switching strip 14 out, which in turn with a Connection of a tap changer 16 is connected.
  • the partial windings are 5.3 and 6.3 also concentric with the core and the partial windings 6.1 and 5.2 arranged surrounding, wherein in axial Direction behind each other.
  • the two conductors 7 and 8 connect each the opposite and the one another facing ends of the partial windings 5.3 and 6.3 on Terminal supports 17, 18, 19 and 20.
  • An auxiliary support 21 is used for fixing a conductor 22 between the terminal 9 and the leader 11.
