Recently, the research and development of BD10GSSX 220/380V dual-output silent generator set has been successfully developed by the North Power Research Institute of China North Industries Group Corporation (NORINCO GROUP). After testing, all performance indicators have met the design requirements. At present, the prototype has been delivered to railway engineering users for installation and trial. The BD10GSSX dual-output generator set can output 220V single-phase AC and 380V three-phase AC at the same time. The 220V single-phase power output is 6kW, and 380V three-phase power output is 4-10kW, which can meet the requirements of using single-phase and three-phase AC at the same time in field operations. Through technical innovation design, the unit fundamentally solves the technical problem of three-phase AC output imbalance when a single excitation generator outputs single-phase and three-phase AC at the same time. This technology adds a "new member" to the company's twin-cylinder machine and its series products, and will become a new economic growth point for the company's development.
