FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical equipment and electric power engineering. Electromechanical insert comprises mechanically connected by shaft (3) asynchronized machines (1 and 2), rotors connected to frequency controllers (4 and 5), which each through transformers (6, 7) and switches (8, 9) are connected to different bus systems (12 and 13); stators of machines (1, 2) are also connected to these buses. Novelty consists in the fact that on each side between stators and buses its stator switch (10, 11) is connected, and short-circuiting switches (14, 15) are connected parallel to stators.
EFFECT: technical result consists in improvement of reliability.
