Case
Hangzhou City North Ring Road Tunnel
Recently, Baoxing's rail transit UPS power supply has been safeguarding the North Ring Road Tunnel in Hangzhou, providing reliable power support for the normal operation of its power supply, lighting, ventilation, monitoring systems, fire protection systems, and other equipment.
In order to meet the power supply needs of the North Ring Road Tunnel in Hangzhou, Baoxing Group has tailored a power guarantee system for its power supply system, adopting a smart power system for rail transit, fully stationed at various important locations in the North Ring Road Tunnel, providing high-quality and highly reliable power supply, ensuring the absolute reliability of power supply for the tunnel and equipment.
This time, Baoxing's rail transit UPS power supply is applied in the North Ring Road Tunnel in Hangzhou; it uses advanced DSP full digital control processing technology and IGBT high-frequency pulse width modulation technology. The double conversion online topology design ensures that the UPS output is a pure sine wave power supply that tracks frequency, locks phase, stabilizes voltage, and filters noise, unaffected by grid fluctuations. The flexible parallel technology can be applied to different loads and systems, forming an N+1 or N+X working architecture according to customer needs, and can also be configured with up to 8 units of different capacities based on customer requirements. Equipped with output isolation transformers, static bypass switches, and manual maintenance switches, it has high short-circuit resistance and can be applied in demanding industrial environments, suitable for high-performance UPS power supplies for critical applications. Tailored to meet the high standard requirements of the rail transit industry application environment, it provides all-weather power protection for user data centers, critical power supply equipment, and key areas.
