Description
Technical Field
The invention relates to the technical field of cable cooling, in particular to a superconducting cable cooling device.
Background
Superconducting materials are materials that exhibit a resistance equal to zero and magnetic flux repelling properties at certain low temperature conditions, which vary from material to material, and are referred to as critical temperatures. The superconducting cable is designed and manufactured by utilizing the characteristics that the superconducting material becomes superconducting state at the critical temperature, the resistance disappears, the loss is very tiny, the current density is high, and the high-current-carrying superconducting cable can carry large current, and the transmission capacity of the high-current-carrying superconducting cable is far more than that of an oil-filled cable and is also more than that of a low-temperature cable and can reach more than 10000MVA, so that the high-current-carrying superconducting cable is a novel cable in great research and development. Since the critical temperature of superconductors is typically below 20K, superconducting cables are typically run in 4.2K of liquid helium.
At present, the demand of China for electric power is increasing, and the transmission capacity and the transmission distance of an electric power system are required to be increased. Conventional cables are made of copper or aluminum and have a line loss of about 15% during transmission. The line loss in the annual power transmission process in china exceeds hundreds of billions of kilowatt-hours. Compared with the traditional cable, the superconducting cable has the advantages of large capacity, low loss, small volume, light weight, high system reliability, resource conservation, environmental friendliness and the like. With the development of superconducting technology, high temperature superconducting cables and high temperature superconducting current limiters are considered as the most likely superconducting devices to be commercially used in electric power systems in the first place. The development of the high-temperature superconducting cable in the world is divided into three important stages of demonstration, sample and industrial application, the high-temperature superconducting cable at present enters the initial development stage of industrial application, the requirements on the length of the high-temperature superconducting cable are continuously increased, the requirements on voltage resistance are continuously improved, and the requirements on current circulation are continuously increased.
Along with the development of high-temperature superconducting materials and corresponding technologies, the manufacture of high-temperature superconducting cables has provided necessary foundation. Because of the relative improvement of the working temperature area, the power transmission cost of the cable manufactured by the high-temperature superconducting material is lower than that of the traditional cable, and the advantages of the cable for direct current power transmission are particularly outstanding. The advantages of high temperature superconducting cable determine its advantages in long distance power transportation.
In long-distance transportation of the superconducting cable, the length of the superconducting cable is continuously increased, the transmission capacity is continuously increased, but because the body and the pipeline of the superconducting cable working at the liquid nitrogen temperature absorb heat from the environment and the loss of electric energy transmitted by the superconducting cable, the increase of the transmission distance can lead to the increase of the heat load of the superconducting cable, and the higher requirements are put forward on the refrigerating system of the high-temperature superconducting cable.
