Product Description and Technical Features
Metro DC traction power supply systems serve as the core electrical backbone of metro operations, converting alternating current (AC) from urban power grids into direct current (DC) of precise voltage levels. These systems transmit power to train traction networks while simultaneously providing protection, control, and energy optimization.
System components typically include:
- Rectifier units in traction substations, costing from hundreds of thousands to millions of dollars per unit
- DC switchgear, priced between USD 50,000 and 200,000 per unit depending on specifications
- Auxiliary systems, such as substation DC power distribution units, costing approximately USD 10,000 to 50,000 per unit
- Monitoring, protection, and control modules for real-time operational safety
Technical advantages:
- Stable DC power delivery ensures uninterrupted train traction
- Advanced protection mechanisms reduce fault propagation and operational downtime
- Energy optimization features support regenerative braking integration and lower energy consumption
- Modular design allows scalability across medium- and high-capacity metro networks
