Case
Longzhang Expressway
The Longzhang Expressway is 41.76 kilometers long, with a roadbed width of 25.5 meters and a dual-direction four-lane highway. The section uses asphalt concrete pavement, while the toll stations and toll plazas use cement concrete pavement. The tunnel section uses a composite pavement. There are two toll stations along the entire line, one service area, one maintenance work area, and four tunnel maintenance stations and substations.
Due to the special nature of highway tunnel applications, EPS emergency power supplies are used, with the load mainly distributed among emergency lighting, fire protection, and ventilation systems. These application systems in the tunnels ensure the safe operation of vehicles and personnel in the highway tunnels.
The successful opening of the Longzhang Expressway project adds another classic case to the application of Baoxing in the rail transit industry. With stable product quality, strong technical strength, and a mature service system, Baoxing has become the power solution supplier for the Longzhang Expressway. To ensure the construction of the Longzhang Expressway project, Baoxing Group has tailored an electricity guarantee system for its power system, using multiple UPS uninterruptible power supply systems and EPS fire emergency power supplies, among other power supply equipment, stationed at various important locations along the Longzhang Expressway to provide high-quality and highly reliable power supply, ensuring the absolute reliability of power supply for the Longzhang Expressway and its equipment.
The Baoxing rail transit series UPS power supply system features stable performance and ultra-high reliability, designed with advanced IGBT high-frequency switching sine pulse width modulation technology, which gives the UPS advantages such as good power supply quality and high efficiency. It not only provides reliable and high-quality grid power to the power system but also offers comprehensive protection for the entire system and network data, ensuring the stability of power supply for the system and other critical equipment, reducing the workload of equipment maintenance personnel, significantly improving the reliability of the service system, achieving scientific management of electrical energy, and laying a solid foundation for the safety of power supply system electricity.
