1, power transmission
Superconducting technology can be applied to the field of power transmission. High temperature superconducting cables made of superconducting materials can reduce power loss during transmission and improve transmission efficiency and quality. In traditional cable transmission, about 10% of electric energy will be converted into heat energy and consumed due to resistance and other reasons, while superconducting cables can reduce the consumption of heat energy by reducing the resistance, thus reducing the waste of energy.
2. Medical field
Superconducting technology can be applied to the medical field. Using superconducting materials to make the core components of nuclear magnetic resonance vibration instrument can improve the stability and image quality of the instrument. Nuclear magnetic resonance vibrometer is a kind of equipment widely used in medical diagnosis and treatment. Magnets made of superconducting materials can generate high-intensity magnetic fields and improve the detection ability of lesions.
3. Transport field
Superconducting technology can be applied in the field of transportation. Superconducting materials can be used to manufacture key components in maglev trains and high-speed rail transit systems to improve the stability and efficiency of transportation. Maglev train is a technology that levitates the train by using magnetic field force. Magnets made of superconducting materials can generate strong magnetic fields and realize the suspension and propulsion of trains.
The main characteristics of superconducting technology:
1, high efficiency
Superconducting technology can realize lossless power transmission and reduce the loss during power transmission. Because superconducting materials exhibit zero resistance at low temperature, it can minimize the generation of heat energy and improve transmission efficiency. Under the same transmission power, superconducting cable can reduce energy loss by about 30% compared with traditional cable.
2. High speed
Superconducting technology can realize high-speed operation. Because superconducting materials show zero resistance at low temperature, the energy of magnetic field will not be dissipated because of resistance, so high-speed operation can be realized. The speed of superconducting maglev train can reach more than 500 kilometers per hour, which is faster than traditional trains.
3, high stability
Superconducting technology can achieve high and stable operation. Because superconducting materials exhibit zero resistance at low temperature, magnetic field energy will not be dissipated due to resistance, so high and stable operation can be realized. Superconducting cable will not cause temperature change due to heat energy during operation, thus avoiding unstable operation caused by temperature change.
