Title:
HIGH-TEMPERATURE SUPERCONDUCTING CABLE TEMPERATURE MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/151032
Kind Code:
A1
Abstract:
A high-temperature superconducting cable temperature measurement system, which is applied to a high-temperature superconducting cable (11) and terminal cooling systems (4) which are connected to each other, comprising: low-temperature temperature measurement optical fibers (9) provided in the high-temperature superconducting cable (11), and thermal resistors (5) provided in the terminal cooling systems (4); an optical fiber temperature measurement host (1) for receiving temperature measurement information from each measurement point of the low-temperature temperature measurement optical fibers (9); a thermal resistor temperature monitor (2) for receiving temperature information from the thermal resistor (5); a temperature measurement and control device (3) for receiving the temperature measurement information and the temperature information, performing evaluation and determination according to the temperature measurement information and the temperature information to determine a protection action and a protection region of a cable operation control host (6) connected thereto, and controlling the cable operation control host (6) to perform corresponding operations. The present system has the features of easy use and simple structure, etc., and can accurately monitor and position temperature abnormal points of the high-temperature superconducting cable, facilitating clearing of faults during maintenance and test of the superconducting cable, reducing the fault range, and reducing the fault processing time.
