Zhuzhou, the first domestic ship's MW permanent magnet generator, rolled off the assembly line
This generator uses a fully enclosed structure. Its new rotor cooling structure and titanium alloy air water cooler solve the heat dissipation problem of high-power permanent magnet generators. Its efficiency is greater than 97%. Compared with traditional excitation synchronous generators, the volume is reduced by 30% and the weight is reduced by 35 %, Has the advantages of simple structure, high efficiency, high reliability, and low maintenance, which fills the gap in domestic technology research in this field. The motor provides a new power supply mode with a lower life cycle cost for ship operation. It is an ideal choice in the field of ship power generation and has broad development prospects. At present, this type of generator has completed the type test and diesel engine unit test. The test results meet the relevant industry standards and technical specifications, and the overall technical indicators have reached the international advanced level. As a power supplier of the entire ship, the generator is the core part of the electric propulsion system and is known as the "power heart". Due to the small installation space of the ship, the large vibration of the rigid connection with the diesel engine, the complex marine operating environment, the hull bumps and many other factors, the generator must meet the multi-operating requirements of a wide range of power changes, and it requires high efficiency and high reliability , High power density per unit volume, anti-salt spray, anti-corrosion and other technical features. Relying on advanced, mature and reliable high-speed railway permanent magnet traction motor and wind power permanent magnet generator technology, CRRC Zhuzhou Motor successfully overcomes a series of difficulties such as short cycle, high requirements and no precedent, and successfully developed China's first megawatt ship Permanent magnet generators have broken the monopoly of international giants in developed countries. |
