DEVICE FOR TRANSMISSION OF ELECTRIC ENERGY FROM FIXED UNIT TO ROTARY PART Russian patent published in 2010 - IPC H01R39/64 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering, in particular to devices for continuous current pickup and distribution of electric energy, and may be used to transmit electric energy in antiicing systems of aircraft rotary blades. Power current collector comprises contact pairs of rings and brushes for transmission of electric energy from external source to current collectors arranged on rotary part and for grounding. Additional current collector comprises contact pairs of rings and brushes for transmission of electric control signals from control system to commutators. Contact rings are insulated from each other and installed on bush made of dielectric and fixed on immovable axis. Each current pickup brush, which contacts with according ring of power current collector, is connected parallel with all commutators, number of which is equal to number of parallel switched current collector groups. Protective cap installed over end surface insulates switched current collectors and commutators againt outdoor environment. On periphery of end surface there are sockets arranged with electric slots for connection of current collectors. Electrically controlled commutators that commute lines of electric energy transmission from power current pickup to independent current collectors are fixed and balanced on end surface inverted towards current collectors. Spring-loaded current collector brushes are with tangential direction towards contact rings of current collectors, besides, with contact end towards sliding direction along contact ring. Contact pairs of power current collector and common electricity cable of additional current collector include at least two current-collector brushes, which are installed at diametrically opposite sides of contact rings as connected by links between each other. Contact pairs of additional current collector comprises one current collector brush each, which are installed in turns on diametrically opposite sides of contact rings as they are arranged along their common axis of current collectors.

EFFECT: simplified design and expanded functional resources, device comprises power and additional current collectors.
