The tool adopting a vertical lifting and assembling method is convenient to use.
Description
technical field [0001] The invention mainly relates to the field of full-length through gauges and detection methods, in particular to a detection tool and detection method for the cylindricity of the sleeve inner hole of a FEEDER current lead heat exchanger. Background technique [0002] ITER large-scale superconducting magnet feeder system (FEEDER) is one of the important systems of the International Thermonuclear Experimental Reactor, which is mainly used for power supply, cooling, measurement and diagnosis of each superconducting magnet coil system in the device. High temperature superconducting current leads (high temperature superconducting current leads) is one of the core components in the FEEDER procurement package. Its function is to convert the small current at normal temperature into a large current at low temperature, and provide the maximum current for the superconducting magnet coil. The sleeve and the heat exchanger are two key components of the current lead...
