Abstract

The embodiment of the invention provides an involute superconducting fault current limiter current limiting unit. The current limiting unit comprises a supporting framework, winding superconducting tapes and inter-tape supporting wavy tapes. One end of each winding superconducting tape is fixed on the supporting framework, and the other end of the winding superconducting tape is outwards wound on the supporting framework layer by layer in an involute geometrical shape; the inter-band supporting wave tapes are arranged between the adjacent winding superconducting tapes, the inter-band supporting wave tapes are of a gradually-changed unequal-period structure, and the effective supporting height of the inter-band supporting wave tapes is increased along with the development of the outer edge of the inter-band supporting wave tapes. The embodiment of the invention provides the involute superconducting fault current limiter current limiting unit which is simple in structure and not complex to process and manufacture.

Description

technical field [0001] The invention relates to the technical field of superconducting current limiting, in particular to a current limiting unit of an involute superconducting fault current limiter. Background technique [0002] Superconducting Fault Current Limiter (SFCL) is a fast and effective current limiting device developed using superconducting technology. Among them, the resistive superconducting DC current limiter makes full use of the zero resistance and state transition characteristics of superconductors, and has significant advantages such as simple structure, strong anti-disturbance ability, and small impact on power systems, and has broad application prospects. The principle of the resistive superconducting current limiter is to limit the fault current of the power system by using the superconductor to change rapidly from the superconducting state (no resistance) to the normal state (high resistance). This type of superconducting current limiter is usually co...
