Device for separately transmitting multiple electric powers on a turbomachine rotor

A device for separately transmitting multiple electrical powers on a turbomachine rotor rotatably mounted relative to a stator, comprising:

• a circuit, named the main circuit, for transmitting electrical power, comprising:
• electrical conductors, named the main conductors (13) of the stator, which are rigidly connected to the stator and connected to at least one source of electrical power, named the main source, which is suitable for providing electrical power, named the main power,
• electrical conductors, named the main conductors (14) of the rotor, which are rigidly connected to the rotor and connected to at least one main electrical load (16) supported by the rotor in order to supply said rotor with main power,
• a device (15) for establishing a rotary electrical connection between the main conductors of the stator and the main conductors of the rotor, said device being capable of ensuring transmission of electrical power therebetween,
• at least one circuit, named the secondary circuit, for transmitting electrical power, named the secondary power, comprising:
• at least one electrical conductor, named the secondary conductor (28) of the stator, which is rigidly connected to the stator and connected to a source of electrical power, named the secondary source, which is separate from each main source and is capable of providing the secondary power in the form of a power signal at a predetermined frequency, named the secondary frequency, which is selected to allow selective, interference-free transmission of the secondary power on the main conductors of the stator and of the rotor and by means of the device (15) for rotary electrical connection, separately from the transmission of main power to each main electrical load,
• at least one device, named a stator coupling device, for electrically coupling each secondary conductor (28) of the stator to at least one main conductor of the stator, named the mixed conductor of the stator, the stator coupling device being suitable for supplying each mixed conductor of the stator with secondary power provided by each secondary conductor (28) of the stator.
