Description
Technical Field
The utility model relates to a submarine cable technical field especially relates to an intelligence photoelectricity composite submarine cable system.
Background
Submarine cables (submarine cables) are wires wrapped with insulating materials and laid under the sea floor and river water for power transmission and communication transmission. Submarine cables are divided into submarine power cables and submarine communication cables. The submarine power cable is mainly used for transmitting high-power electric energy underwater, has the same effect as an underground power cable, and is different from the submarine power cable in application occasions and laying modes. Submarine communication cables are mainly used for communication services, are expensive, and have high confidentiality. Since submarine cable engineering is a large-scale engineering recognized as complicated and difficult by countries all over the world, and complicated technologies are applied to environmental exploration, marine physical investigation, and cable design, manufacture, and installation, manufacturers capable of providing manufacturing and installation technologies for submarine cables are few in the world.
In 1850 the first submarine communications cable was laid between the united kingdom and france worldwide, in 1951 the first 22kV submarine power cable was laid in the mingshi strait of japan worldwide, and in 1986 the first 220kV submarine power cable in china, built by sumitomo of japan, was laid in the zhangjiang tiger. At present, China already has two circuits of submarine power cables with 500kV voltage level manufactured in China.
China has a coastline which is over 18000 kilometers, so that a plurality of islands can be developed and utilized, offshore wind energy resources are quite abundant, meanwhile, the Bohai sea, the yellow sea and the south sea all have a great deal of resources such as petroleum, natural gas, combustible ice, metal deposits and the like for storage, the resources can be developed without transmitting energy and information of submarine cables, and the development of the submarine cables inevitably promotes the development and utilization of the submarine resources. In recent years, with the exhaustion of global fossil energy and the increasing demand for electric power by human beings, new energy industries are vigorously developed in the world, and the development of new energy in the marine field is more controversial by various countries, such as offshore wind turbine power generation, marine tidal energy, marine natural gas and oil exploitation, and only one channel from marine new energy to land use is provided, namely, a submarine cable. Submarine cable transmission engineering is also an important component of cross-sea area networking engineering construction, and has important significance in the process of realizing power grid internationalization and regional power grid interconnection.
The official grid-connected power generation of the offshore wind power project of the east-sea bridge near the sea in 2010 is used as a mark, and the offshore wind power construction is built in China, so that the large screen is opened. According to the forecast of relevant mechanisms, the whole offshore wind power resource in China reaches 7.5 hundred million kilowatts, which is 3 times of the land wind power resource. By taking the wind power development planning of Jiangsu province of coastal wind energy resource great province as an example, the installed capacity of the wind power generation planned by the whole province will exceed 1000 ten thousand kilowatts in 2020, and reach 2100 ten thousand kilowatts in the long term.
The electric energy generated by offshore wind power generation construction is collected by submarine cables of 35kV or below and is transmitted outwards through submarine cables of 110kV, 220kV or higher voltage level, which undoubtedly brings huge market demand to the submarine cables. The long-distance transmission also brings opportunities and challenges to the ultra-high voltage and ultra-long length direct current submarine cables, and forms a huge market demand.
The submarine power cable is required to have excellent electrical insulation performance, and also have high corrosion resistance, water resistance, mechanical stress resistance and the like. Therefore, research, development, production and manufacturing of submarine cables will play a certain role in promoting and guaranteeing the development and utilization of ocean wind power generation, ocean oil and gas exploitation, harbor construction and islands.
Submarine cables, which are only part of the submarine cable project, are also known as "pearl on crown" for cable manufacture because of their high standards, high thresholds and high risks. Submarine cable engineering construction relates to the technical field extensively, and the investment scale is great, and the construction technology is complicated. The engineering construction period generally can be divided into two stages, and work in earlier stage of construction mainly relates to engineering design, submarine cable route selection, submarine cable manufacturing and transportation, then mainly contains submarine cable route location, submarine cable laying, submarine cable protection, land equipment fixing, detection and debugging, engineering acceptance check during the engineering construction period. The importance of submarine cables is determined by the characteristics of submarine cable engineering, and the monitoring of the performance and environment of submarine cables is particularly important.
