Problems solved by technology

AC loss is the loss produced by the superconducting strip when it is transmitting alternating current or under an alternating magnetic field. If this parameter is too large, the thermal effect of the superconducting power equipment will be obvious and the overall equipment will be unstable. It is necessary to optimize and reduce the power equipment design. parameter

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0036] Since the existing twisting machine is not suitable for twisting the new type of superconducting wire with a square cross section, if twisting by hand will cause problems such as low efficiency and uneven lay distance, it will not be possible to realize industrial production , so this patent designs a twisting device for a single superconducting stacked wire. Increase the critical current, reduce AC loss, and improve the overall electromagnetic characteristics.

Abstract

The invention relates to a high-temperature superconducting stacked wire twisting device and an operating method thereof. The device comprises a case, a fixing mechanism and a twisting mechanism, wherein the case is of a hollow structure; the fixing mechanism is arranged in the case; the twisting mechanism is arranged in the case; and a stacked wire respectively passes through the fixing mechanismand the twisting mechanism. Compared with the prior art, the device has the beneficial effect of being capable of achieving the twisting of the superconducting stacked wire. Compared with the conventional manual twisting, the device not only improves the twisting efficiency, but also is more uniform in distribution of the twisting pitch of the twisted stacked wire.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a high-temperature superconducting stacked wire twisting device and a working method thereof. Background technique [0002] Due to their high current-carrying capacity beyond conventional conductors, superconducting materials are widely used in power equipment, including superconducting cables, superconducting energy storage, superconducting current limiters, superconducting transformers, etc. However, the current-carrying capacity of a single superconducting tape is limited, and its aspect ratio limits the application of the tape. Therefore, if the superconducting tape wants to move from the laboratory to the industrial world, its electromagnetic and mechanical properties need to be further improved. Among them, stacking superconducting tapes has become a commonly used means to increase the critical current of superconducting wires due to its simple technical process and s...
