Problems solved by technology

The superconducting current lead and the connected superconducting power device will suffer from a quench phenomenon due to excessive current, resulting in a rise in temperature. Local overheating may burn the insulating protective cover or melt the conductor. At the same time, the quench may also generate high voltage and cause insulation. A series of problems such as breakdown, so the protection of the current lead is very important. In the past patents related to the current lead, most of them were related to the optimized heat leakage of the current lead, and the factor of quench protection has not been considered

Description

Technical field [0001] The invention relates to a binary current lead, in particular to a high-temperature superconducting binary current lead. Background technique [0002] Superconducting devices work under lower temperature conditions, and usually need to be powered by a room temperature power supply through a current lead. The current lead crosses the room temperature zone and the low temperature zone of the superconducting device. Conventionally, the current lead is made of copper and works at the same time. There is conduction heat generated along the lead and Joule heat generated by current, and its leakage heat accounts for most of the leakage heat of the entire low-temperature system. To this end, high-temperature superconducting materials are used to make binary current leads, the upper end of which is a copper lead, which is connected to the power supply at room temperature; the lower end is a high-temperature superconducting tape, which is connected to the superconduc...
