[0002] With the increasing global awareness of environmental protection and the strict restrictions on ship emissions by the International Maritime Organization (IMO), the use of shore power systems to provide electricity to ships to reduce pollution caused by diesel engines used by ships during docking has become a widely adopted solution. Shore power systems can effectively reduce air pollution in port areas, improve the environmental quality of port cities, and reduce greenhouse gas emissions.
[0003] Although shore power technology has brought many environmental and economic benefits, traditional shore power systems face some limitations and challenges in practical applications. First, traditional shore power piles can usually only serve one ship, which is not flexible and efficient in large ports where ships are densely docked. In addition, with the different requirements of various types of ships for shore power interface standards, it is necessary to provide a shore power system that can adapt to multiple interface standards to meet the needs of different ships.
[0004] In addition, when using traditional shore power systems, ships often need to open the electrical cabinet door for connection and testing, which not only increases the complexity of operation, but also may bring safety hazards, especially in severe weather conditions, the risk of directly operating electrical components increases. At the same time, traditional shore power equipment often lacks effective heat dissipation design, which can easily cause equipment overheating when running for a long time, affecting service life and safety.
[0005] Therefore, the development of a multi-interface low-voltage shore power pile that can provide power to multiple ships at the same time and has higher safety, convenience and applicability has become an urgent need for the development of the industry. The new shore power pile should have the characteristics of easy maintenance, efficient heat dissipation, waterproof and dustproof, so as to adapt to the complex and changing environmental conditions of the port and provide a more reliable and environmentally friendly power supply solution.
