Description
For DC traction substations of metros, tramways and railways at 600, 750, 1,500 and 3,000 V, the manufacturer supplies the main equipment: rectifier transformers, traction rectifiers, regenerative inverters, DC switchgear and packaged substations.
The rectifier units are designed for power up to 6 MW and connection to a grid with a voltage up to 77 kV. Heat-pipe self-cooling without fans is used. Rectifier transformers are built with mineral or vegetable oil, liquid silicone, gas or cast epoxy insulation (up to 35 kV). The equipment complies with the JEC and IEC standards.
Regenerative inverters return to the AC supply network the regenerative braking energy that other rolling stock cannot accept. Example parameters are 1,000 kW continuous, 3,000 kW for 1 min or 4,500 kW for 30 s, input voltage 1,200 V AC, with air-insulated or solid-insulated design.
The packaged DC substation (Package-Type DC Substation) combines in one module an incoming 7.2, 24 or 36 kV switchgear with air or solid insulation, a transformer, a 12-pulse rectifier rated up to 2,000 kW, 600 or 1,500 V DC cubicles with high-speed circuit breakers (HSCB or vacuum HSVCB) and a 110 V DC control power supply. It suits low-power substations and shortens construction time. Digital DC feeder relays protect against current steps (ΔI) and rate of current rise (di/dt).
The equipment has been supplied for the ROCA line (Argentina), the Thai Purple Line and Taiwan High Speed Rail. Rectifier transformers and switchgear are produced at the manufacturer's plants in Japan, and medium-voltage cubicles also in Malaysia and China. Applications are traction substations of DC metros, tramways, suburban and main-line railways, and substation modernization.
