Description

technical field [0001] The invention relates to a monitoring device, in particular to a temperature monitoring and control device for a carbon ceramic temperature sensor. Background technique [0002] In 1911, Dutch physicist Camerin Onnes discovered superconductors. Superconductors have unique physical properties such as zero resistance, complete diamagnetism and quantum tunneling effect. Since the discovery of superconductors, superconductivity and its applications have been one of the most active frontier research fields in contemporary science and technology. In energy, It has important application value in information, transportation, scientific instruments, medical technology, national defense and major scientific projects. Superconductivity was first discovered in mercury by Dutch physicist Onnes in 1911. It refers to the phenomenon that the resistance of a superconductor suddenly disappears when the temperature drops to a certain value. This characteristic tempera...

Problems solved by technology

However, the high-temperature superconducting tape, the main component of the high-temperature superconducting magnet, is generally in the environment of high voltage and strong magnetic field, which is difficult for temperature monitoring.

Especially for high-temperature superconducting magnets under the condition of conduction cooling, it is not only necessary to monitor the temperature of local overheating, but also the monitoring system itself must ensure that no external heat can be introduced casually, which will aggravate the danger of potential hot spots, because for the first The second-generation high-temperature superconducting tape, the superconducting layer of the tape itself is very thin, and the volume of the superconducting tape per unit length is small, so the heat capacity is small, and the temperature rises quickly when quenching. system quench and burn
