Two-sided immersion superconducting solenoid coil

Abstract

The invention relates to a double-side immersed superconducting solenoid coil, comprising a coil frame (1) and a superconducting tape (2); wherein the superconducting tape (2) is winded spirally on the coil frame (1); the superconducting solenoid coil is provided with a supporting piece (3); the supporting piece (3) is arranged between the coil frame (1) and the superconducting tape (2) to support the superconducting tape (2); a gap is arranged between the coil frame (1) and the superconducting tape (2). With the gap between the coil frame (1) and the superconducting tape (2), the invention has the advantages that the two sides of the superconducting tape (2) are both immersed into the liquid nitrogen or the liquid helium, which improves the heat transfer capacity of the superconducting coil and prevents the superconducting coil from performance degradation or being burned out because of the over high heat output under the state of quenching superconductivity.

Description

technical field [0001] The invention relates to a superconducting power device, in particular to a double-sided soaked superconducting helical coil. Background technique [0002] Superconducting power devices are one of the important development directions in the field of electric power science and technology. The core of most superconducting power devices, such as superconducting magnets, superconducting current limiters, superconducting motors and superconducting transformers, is one or more superconducting coils, which can be soaked in liquid nitrogen or liquid Cooled in helium, maintaining its superconducting state. The superconducting coil can be wound by superconducting wire or superconducting tape, and its shape can be wound into a pie coil or a solenoid coil. The pie coil is easy to make input and output taps, and is also easy to fix by impregnating epoxy ; The solenoid coil has a simple structure, and compared with the pie-shaped coil, it has a large contact area ...
