China Shipbuilding Industry Corporation Institute of the seventh 112 recently successfully developed the first set of independent intellectual property rights with the ship's medium voltage 3 MW electric propulsion system and core equipment - the pressure to promote the inverter , motor and so on, and has passed China Classification Society certification. It is understood that the power propulsion system can be customized according to customer requirements, the vast majority of ships using electric propulsion methods are high-tech, high value-added ships. Compared with the traditional marine power plant directly propelled by diesel engines and steam turbines, it has the obvious advantages of improving performance, optimizing the ship shape, reducing noise, saving maintenance costs, increasing the available space in the cabin, and superior flexibility, so as to provide ships with more Advanced and smarter "heart" with bright future in marine and offshore engineering. For a long time, the core equipment of electric propulsion ship built in our country has been relying on imports, and this achievement has achieved "zero breakthrough" for self-developed core equipment of ship electric propulsion, which indicates that China already has the design and manufacture of large-capacity medium-voltage electric propulsion system for ships Ability to become one of the few countries in the world that has mastered the medium voltage power propulsion system and core equipment of ships. This is of strategic significance for a comprehensive breakthrough in the application of high-tech vessels for the core equipment of electric propulsion and self-developed research and development, improvement of the design and manufacturing capacity of the national marine engineering equipment, and promotion of the transition from a big shipbuilding nation to a shipbuilding power.
