DEVICE FOR PHASE-TO-PHASE CURRENT DISTRIBUTION Russian patent published in 2019 - IPC H02J3/26 

FIELD: electrical engineering.

SUBSTANCE: device for phase-to-phase current distribution comprises three single-phase transformers, windings of which are each made with a middle lead, are connected by extreme leads to a "triangle", the vertices of which are connected to phase input terminals, zero input terminal, a consumer connected to a zero input terminal and at least to one phase input terminal, a balancing reactor with three identical windings connected to the same input terminals to the zero input terminal, and by free leads - to the transformer windings middle leads. Technical result achieved in the proposed device consists in elimination of non-efficient power losses for the IPCD windings heating. Additional technical result achieved in the proposed device consists in equalizing values of consumed phase currents. Besides, the device can be used for energy recuperation both in case of consumer connection between three phase and zero input terminals, and in case of its connection between one of phase and zero input terminals. This is ensured by circulation of a third of energy between the IPCD and the consumer bypassing the power supply network. Magnetic cores of IPCD transformers and equalization reactor can have different configurations, including a twisted band-shaped ribbon.

EFFECT: invention can be used to increase energy efficiency of single-phase and three-phase consumers by recuperation of consumed energy due to circulation of its part between consumer and proposed device of inter-phase current distribution (IPCD).
