Устройство относится к электрификации железных дорог на переменном токе по системе 2 х 25 кВ для совместного питания тяговых и нетяговых потребителей. Предлагаемое устройство содержит тяговую систему электроснабжения 2 х 25 кВ с трехобмоточными тяговыми однофазными трансформаторами, снабженную двумя разъединителями и выключателем на вторичной стороне резервного трансформатора для организации полного треугольника напряжений, питающего трехфазные потребители линий ДПР и СН подстанций, которая дополнена тем, что вторые вторичные обмотки тяговых трансформаторов в обоих плечах подстанции и резервного трансформатора шунтированы через свои двухполюсные разъединители конденсаторными батареями и соединены между собой в треугольник через однополюсный разъединитель. Кроме того, батареи конденсаторов выполнены в виде совокупности переключаемых "К" ступеней, значения емкостей каждой из которых выбраны из условия резонанса тока в цепи второй вторичной обмотки каждого из трансформаторов для К-й гармоники. Повышение качества электроэнергии в питающей высоковольтной сети достигается путем подавления гармоник тока и симметрирования напряжения на вторичной стороне и в магнитных цепях тяговых трансформаторов.The device relates to the electrification of railways on alternating current on the system 2 x 25 kV for the joint supply of traction and non-traction consumers. The proposed device contains a traction power supply system of 2 x 25 kV with three-winding single-phase traction transformers, equipped with two disconnectors and a switch on the secondary side of the backup transformer for organizing a full triangle of voltages supplying three-phase consumers of DPR and CH lines of substations, which is complemented by the fact that transformers in both shoulders of the substation and backup transformer are shunted through their two-pole disconnectors with capacitor atareyami and interconnected in a triangle through the single-pole disconnector. In addition, capacitor banks are made as a set of switchable "K" stages, the values of the capacitances of each of which are chosen from the condition of current resonance in the second secondary winding circuit of each of the transformers for the K-th harmonic. Improving the quality of electricity in the supply high-voltage network is achieved by suppressing current harmonics and balancing the voltage on the secondary side and in the magnetic circuits of the traction transformers.
