The rotating power supply of marine central collector is a technology used to supply power to rotating components of ships. It enables equipment on ships that require rotation, such as cranes and radars, to continuously obtain power during rotation.
The development trends of rotating power supply for marine central collectors are mainly reflected in the following aspects:
Adapting to the development of medium-voltage DC integrated power systems:
The integrated power system of ships is evolving along the technical trajectory of "medium-voltage AC - high-frequency AC - medium-voltage DC". The medium-voltage DC power supply system has many advantages, such as the prime mover speed is not affected by frequency, and the volume and quality of the system can be reduced.
Improving power transmission capacity and efficiency:
With the enlargement of ships and the increase of high-power equipment on board, such as large cranes, the requirements for the power transmission capacity of central collectors are constantly improving.
Enhancing reliability and stability:
The navigation environment of ships is complex, so the central collector needs to have higher reliability and stability.
Realizing intelligent control and monitoring:
With the development of ship intelligence, the central collector will be integrated into the ship's intelligent management system. Remote monitoring and automatic control can be realized through sensors and communication technologies.
Developing towards miniaturization and lightweight:
In order to optimize the spatial layout of the ship and reduce the weight of the ship, the central collector will develop towards miniaturization and lightweight.
The maintenance of marine central collectors is crucial to ensure their stable power supply and extend their service life.
-
Appearance and connection: Check whether the collector shell is intact, and whether the cable joints and terminals are loose or overheated and discolored. Ensure reliable electrical connection to avoid sparks or heating caused by poor contact.
-
Contact between carbon brush and slip ring: Observe whether the carbon brush is closely attached to the surface of the slip ring, and whether there is obvious jumping or jamming; Check whether the surface of the slip ring has spark marks, oil stains or foreign matters. If so, clean them in time to prevent increased wear or poor conductivity.
-
Abnormal noise and vibration: When running, monitor whether there is abnormal noise (such as friction noise, metal collision sound) and feel whether the equipment vibration is too large. Abnormalities may indicate bearing wear or loose components.
-
Regular maintenance and cleaning:
-
Clean the slip ring and carbon brush with dry compressed air to avoid insulation reduction or poor contact caused by impurities.
-
Inspection and replacement of carbon brushes
