Abstract

The invention provides a shipping high-voltage shore power system. The output power adopts AC6.6KV/60Hz or AC6KV/50Hz; the shipping high-voltage shore power system comprises a shore-based part and a shipborne part, wherein the shore-based part comprises a high-voltage wire-inlet switch cabinet, a high-voltage frequency converter, an isolating transformer, a wire-outlet switch cabinet, a measuring cabinet, a high-voltage shore power junction box and a PLC monitoring cabinet; the shipborne part comprises a high-voltage cable reel, a shipborne high-voltage shore power connection power distribution cabinet, a shipborne high-voltage shore power measuring protection cabinet, a shipborne transformer and a shipborne shore power access control screen. The shipping high-voltage shore power system adopts a high-voltage boarding manner, and the output power adopts AC6.6KV/60Hz or AC6KV/50Hz; therefore, the shipping high-voltage shore power system is suitable for shore-based power supply for ports, and can be applied in a convenient, rapid and effective manner; power supply for ships in berthing periods is realized; and the shipping high-voltage shore power system is energy-saving, environment-friendly, and regarded as a part of green ports.

Description

technical field [0001] The invention relates to a shore power system for supplying power to ships, in particular to a high-voltage shore power system for ships. Background technique [0002] In recent years, the concept of "green port" has continuously appeared in various cutting-edge scientific and technological fields. Environmental protection projects and the promotion and application of clean energy have become planning projects for major ports. [0003] Seven of the top ten container ports in the world are in China. Ships and trucks moving in and out of the port, while bringing goods and economic development, also contribute to air pollution in the port and surrounding areas. The main air pollutants emitted by ships, port freight vehicles and port equipment include particulate matter, sulfur dioxide and nitrogen oxides. These pollutants have negative impacts on air quality, climate change and human health. In 2014, in Shanghai, Shenzhen, Tianjin and other inland port...
