Abstract
A high power electrical distribution system for distribution high power to at least one consumer arranged on a rotatable element. The distribution system includes at least one high frequency alternating current HFAC generator configured to generate HFAC. A rotary power transformer is connected to the at least one HFAC generator. The rotary power transformer includes a stationary part and a rotatable part and is configured to receive HFAC from the at least one HFAC generator and to couple HFAC electrical energy from the stationary part to the rotatable part. At least one high power distribution bus is located on the rotatable element and is configured to receive HFAC from the rotary power transformer and to distribute HFAC to the at least one consumer.
Claims15
A high power electrical distribution system for distribution high power to at least one consumer (12) arranged on a rotatable element (3), characterised in that said distribution system comprises:
- at least one high frequency alternating current HFAC generator (4) configured to generate HFAC,
- a rotary power transformer (2) connected to said at least one HFAC generator (4), wherein said rotary power transformer (2) includes a stationary part (7) and a rotatable part (8), and is configured to receive HFAC from said at least one HFAC generator (4), and to couple HFAC electrical energy from said stationary part (7) to said rotatable part (8), and
- at least one high power distribution bus (11) located on said rotatable element (1), and configured to receive HFAC from said rotary power transformer (2) and to distribute HFAC to said at least one consumer (12).
A high power electrical distribution system according to any of the preceding claims, characterised in that said rotatable element (3) is a sensor or an antenna, in particular a rotating radar antenna of a phased-array radar system.
A high power electrical distribution system according to any of the preceding claims, characterised in that said rotatable element (3) includes more than 100 separate consumers (12), and preferably more than 500 separate consumers (12), and more preferably more than 1000 separate consumers (12).
A high power electrical distribution system according to any of the preceding claims, characterised in that the HFAC generator (4) is configured to feed the rotary power transformer (2) with a HFAC, which has an AC frequency of at least 10 kHz, and preferably of at least 30 kHz, and more preferably of at least 70 kHz.
A high power electrical distribution system according to any of the preceding claims, characterised in that the rotary power transformer (2) is configured to provide an HFAC output of at least 1 kW to said at least one high power distribution bus (11), and preferably of at least 5 kW, and more preferably of at least 10 kW.
A high power electrical distribution system according to any of the preceding claims, characterised in that said rotary power transformer (2) is configured to feed at least two separate high power distribution buses (11), such that said at least two high power distribution buses (11) distribute HFAC having different AC frequency and/or different power levels, or such that said at least two high power distribution buses (11) provide redundancy by distributing identical HFAC in said at least two separate high power distribution buses (11).
Method for distributing high power to at least one consumer (12) arranged on a rotatable element (3), characterised in that said method comprises the steps of:
- generating HFAC in at least one HFAC generator (4),
- transferring HFAC supplied by said at least one HFAC generator (4) to said rotatable element (3) by means of a rotary power transformer (2), wherein said rotary power transformer (2) includes a stationary part (7) and a rotatable part (8), and
- distributing said transferred HFAC from said rotary power transformer (2) to said at least one consumer (12) by means of at least one high power distribution bus (11) located on said rotatable element (3).
