Electrical power supply device for powering at least one piece of equipment of an aircraft rotor, and an aircraft

摘要

An electrical power supply device (10) comprising a pole (11), said pole (11) having a non-rotary casing (15) and a rotary casing (12) provided with fastener means (14) for fastening to a mast. The pole (11) includes a non-rotary converter (20) fastened to the non-rotary casing (15) and generating AC at a frequency higher than one kilohertz. The pole also includes a rotary transformer (25), said rotary transformer (25) having a primary member (26) secured to the non-rotary casing (15) and a secondary member (27) secured to the rotary casing (12), the primary member (26) being connected to the non-rotary converter (20) to receive said AC, and the secondary member (27) being suitable for electrically powering equipment (100) of a rotor (2).

主权项

1. An electrical power supply device for powering at least one piece of equipment of an aircraft rotor driven by a mast, said device comprising a removable pole suitable for being reversibly secured to said mast, said pole having a rotary casing provided with fastener means for fastening to said mast, and a non-rotary casing secured to link means suitable for being fastened to a reference member of said aircraft, wherein said pole comprises:
a non-rotary converter fastened to the non-rotary casing and provided with an inlet suitable for being fed with electricity coming from an electricity network of said aircraft, said non-rotary converter being an electrical converter that generates AC at a frequency higher than one kilohertz from said electricity fed to the inlet; and a rotary transformer incorporated in the pole, said transformer having a primary member secured to the non-rotary casing and a secondary member secured to the rotary casing, the primary member being connected to the non-rotary converter to receive said AC, and the secondary member being suitable for electrically powering equipment of a rotor.
