DEVICE FOR A COMPUTER TOMOGRAPHY GANTRY FOR TRANSFERING CONTACTLESSLY ELECTRICAL ENERGY

摘要

The invention provides a device for a computer tomography gantry (91) for transferring contactlessly electrical energy from a stationary part of the gantry (92) to a rotary part of the gantry (93), wherein the device comprises a first power transformer, a second power transformer, wherein the first and the second power transformers are adapted for transferring the electrical energy, wherein the first power transformer comprises a first winding (506, 507, 542, 602, 601, 1202, 1301, 1401) out of the group consisting of a first set of primary windings and a first set of secondary windings of the first power transformer, wherein the second power transformer comprises a second winding (508, 509, 543, 603, 604, 1204, 1302, 1402) out of the group consisting of a second set of primary windings and a second set of secondary windings of the second power transformer, wherein the first set of primary windings and the second set of primary windings being adapted to be mounted on the stationary part of the gantry, wherein the first set of secondary windings and the second set of secondary windings being adapted to be mounted on the rotary part of the gantry (93), wherein the device is adapted to balance the currents of the first winding and the second winding. A further aspect of the invention is a computer tomography gantry (91) comprising a device according to the inventive concept. Furthermore, it is an aspect of the invention a method for transferring contactlessly electrical energy from a stationary part of a gantry (92) to a rotary part of a gantry (93) comprising the steps of balancing currents with the help of a device according to the invention.
