Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0057] When under a changing magnetic field, the motion of the magnetic force lines inside the high-temperature superconducting bulk is intensified, resulting in a large local temperature rise of the superconductor. The present invention proposes a method for detecting the calorific value of high-temperature superconducting bulk materials. The heat generation of high-temperature superconducting bulk materials under varying magnetic fields is indirectly measured by comparing the evaporation of liquid nitrogen under changing magnetic fields and under stable magnetic fields. Based on the constant evaporation of liquid nitrogen per unit time, comparing the difference between the evaporation of liquid nitrogen under a changing magnetic field and under a stabl...

Abstract

The invention discloses a detection method and device of the heating amount of a high-temperature superconducting bulk material. The method comprises the following steps: under a stable magnetic field, calculating according to the temperature data measured by a sensor arranged at the top in a container in advance to obtain first liquid nitrogen loss amount of the container in a pre-set duration; when the container is located in a changeable magnetic field, calculating according to the temperature data measured by the sensor arranged at the top in the container to obtain second liquid nitrogen loss amount of the container in the pre-set duration; and according to a difference value of the first liquid nitrogen loss amount and the second liquid nitrogen loss amount, calculating to obtain the heating amount of the high-temperature superconducting bulk material, which is arranged in the container, is immersed in liquid nitrogen and is located in the changeable magnetic field, in the pre-set duration. According to the detection method and device of the heating amount of the high-temperature superconducting bulk material, disclosed by the invention, the heating amount of the high-temperature superconducting bulk material, which is arranged in the container, is immersed in liquid nitrogen and is located in the changeable magnetic field, can be accurately estimated.

Description

technical field [0001] The invention relates to a high-temperature superconducting magnetic levitation technology, in particular to a method and a device for detecting the calorific value of a high-temperature superconducting bulk material. Background technique [0002] Compared with the electromagnetic levitation (EMS) and electrodynamic levitation (EDS) technologies based on electromagnetic attraction and repulsion, the high-temperature superconducting magnetic levitation technology relies on the magnetic flux pinning between the high-temperature superconductor bulk and the external magnetic field to achieve self-sustaining Stable suspension. The high-temperature superconducting magnetic levitation technology lowers the temperature of the superconducting block into the superconducting state by soaking it in liquid nitrogen, and the superconducting block in the superconducting state interacts with the external magnetic field to achieve stable suspension. This technology do...
