MODERNIZATION OF THE TRACTION POWER SUPPLY SYSTEM OF THE METRO
Emil Dodov The power supply of the traction power supply system of the metro is carried out by traction power systems (TPS) and lowering stations. The facility whose TPS is being modernized is the ”Obelya” depot. The existing situation, power supply schemes and facilities are discussed below.
The modernization s the replacement of five contact rail disconnectors with new remotely controlled disconnectors at the Obelya depot – RP 1, 2, 3, 4. A comparison of the two types of contact rail disconnectors is made and the advantages and disadvantages are shown. The benefits of building an optical communication network for remote control and signaling of the disconnectors are shown. Разединители на контактна релса телеуправление сигурност и надеждност.Contact rail disconnectors remote control safety and reliability.Emil Dodov BIBLIOGRAPHY [1] Dodov, E., Lalev, T., Izmervane i analiz na energetichnite parametri na tyagova ponizitelna stantsiya v metropolitena, nauchno spisanie „Mehanika, transport, komunikatsii“, tom 22, 2024 g., statiya 2525, str.
