Abstract

The invention discloses a system for automatically controlling the tension of stranded cables of a superconducting cable conductor. The system comprises a stranded wire frame, wherein a pay-off disk is arranged in the stranded wire frame through a rotating shaft; wire guiding wheels are arranged behind the stranded wire frame; a take-up disk is arranged behind the wire guiding wheels; and the take-up disk is connected with a take-up motor. The system also comprises a pay-off motor connected with the pay-off disk; a tension sensor is connected with the wire guiding wheels; signals of the tension sensor are switched in a control circuit in a control cabinet; and a frequency converter of the take-up motor and a frequency converter of the pay-off motor are respectively connected with the control circuit. By adoption of the system, the tension can be accurately controlled, so that wires can be paid off stably, the problem that a tension value cannot be accurately controlled during stranding of superconductive wires is solved, and the problems that the superconductive wires are loosen and nonuniform, are easily snapped and the like during stranding are solved.

Description

technical field [0001] The invention relates to a stranding tension control system of a pay-off reel of a cage stranding machine, in particular to an automatic control system of stranding tension of a superconducting conductor. Background technique [0002] With the development of science and technology, superconducting magnet technology has been applied more and more. The core of superconducting magnet is CICC (Cable-In-Conduit-Conductors) superconducting conductor, which has good self-supporting, low AC It has the characteristics of low loss, less low-temperature cooling medium, safe and reliable operation, and high performance. It is currently internationally recognized as the preferred conductor for large superconducting magnets in controlled thermonuclear fusion devices. [0003] CICC superconducting conductor is a multi-stage tube-mounted cable, which is stranded in five levels. The first-level sub-cable of the conductor is composed of several copper wires and several ...
