Force-thermal coupling loading system for superconducting materials under ultra-low varying temperature environment

Abstract

A force-thermal coupling and loading system for superconducting materials under an ultra-low varying temperature environment comprises a testing machine, a refrigerator, a heating unit and a temperature control unit, wherein the testing machine is an electronic universal testing machine; the electronic universal testing machine uses a cooled cryostat which is in a double vacuum mode; the inside of the cooled cryostat is connected with a vacuum pump through a vacuum pipe assembly; an observation window is further formed in the front of the cooled cryostat; the refrigerator is mounted on the back of the cooled cryostat; refrigeration is carried out in a multi-stage refrigerating head mode; the heating unit comprises a heater, a temperature controller and a temperature sensor; and the temperature control unit comprises an intelligent PID (proportion integration differentiation) regulating and controlling unit, a central arithmetic unit and a human-machine interface (HMI). The force-thermal coupling loading system can be used for testing the performance of the superconducting materials under the ultra-low or varying temperature environment, and has the advantages of large temperature range, small temperature errors, good testing precision, high stability and good simplicity in operation.
