Abstract
An apparatus is provided including a cascaded transformer set and a voltage divider. The cascaded transformer set includes a plurality of transformers, each having a primary and a secondary winding. The secondary winding of one transformer feeds the primary winding of an adjacent transformer. The voltage divider includes a plurality of capacitors and a plurality of resistors configured to divide a voltage applied to the cascaded transformer set among the plurality of transformers. The capacitors of the voltage divider may include a series of disks that are also used in the support structure of the apparatus.
Claims18
An apparatus comprising:
- a cascaded transformer set comprising a plurality of transformers, each transformer having a primary and a secondary winding, and each transformer comprising three insulating gaps, wherein in the cascaded transformer set, the secondary winding of one transformer feeds the primary winding of an adjacent transformer;
- and
- a voltage divider comprising a plurality of capacitors, each of equal value, and a plurality of resistors configured to evenly divide a voltage applied to the cascaded transformer set among the insulating gaps of the cascaded transformer set;
- wherein the plurality of capacitors comprises a plurality of discs, wherein each capacitor of the plurality of capacitors is formed between two discs of the plurality of discs,
- wherein the apparatus further comprises an oil medium surrounding the plurality of transformers and the plurality of discs, and
- wherein the plurality of discs and plurality of transformers are arranged such that each of the plurality of transformers is positioned between two of the plurality of discs.
