FIELD: electricity. ^ SUBSTANCE: invention relates to electrical power engineering, particularly to devices for transmitting energy using alternating current, and more specifically to high-voltage power transmission. The phase-converting device has two main phase-converting transformers, made from a Scott connection and working in antiphase. The neutrals of the phase-converting transformers are connected through switches to an additional phase-converting transformer, also made from a Scott connection. Also the phase converting device can contain devices for regulating voltage across a load, installed on the neutral side of the main phase-converting transformers. ^ EFFECT: increased reliability of operation of four-phase transmission in emergency modes. ^ 2 cl, 4 dwg, 1 tbl |
