FIELD: electrical engineering.SUBSTANCE: to be used in electrical engineering. Technical result is achieved due to the fact that the traction power supply system connection device (40) of the (PF1, PF2, NF1, NF2) of railway track section to three-phase supply network (L1, L2, L3) contains three-phase transformer (42–44, 55–62, 64, 65) and balancing device (41) for the three-phase supply network three phases uniform electric loading (L1, L2, L3), wherein three-phase transformer (42-44, 55-62, 64, 65) on the primary side is suitable for connection to the three-phase supply network (L1, L2, L3), and on the secondary side is to the balancing device (41), wherein three-phase transformer (42-44, 55-62, 64, 65) is suitable for connection to the traction power supply system containing the autotransformer system with two contact conductors (PF, PF2) and two routed isolated along the track section segment conductors (NF1, NF2).EFFECT: prevention of the three-phase supply network electrical load asymmetry during the catenary system two different sections feeding.13 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 664 391 C1 (51) МПК H02J 3/26 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК H02J 3/26 (2006.01); H02M 5/14 (2006.01) (21)(22) Заявка: 2017106321, 14.08.2015 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): СИМЕНС АКЦИЕНГЕЗЕЛЛЬШАФТ (DE) Дата регистрации: 17.08.2018 2014040448 A1, 20.03.2014.
