ADIABATIC PIPE INSULATION UNIT AND SUPERCONDUCTIVE CABLE TRACK

摘要

PROBLEM TO BE SOLVED: To provide an adiabatic pipe insulation unit capable of storing a long member such as core of superconductive cable, electrically insulating a vacuum adiabatic pipe in a longitudinal direction where refrigerant of cryogenic temperature is flowed and reducing cooling load of refrigerant.SOLUTION: There are provided the first cylindrical part connected in communication with one cut adiabatic pipe of two cut adiabatic pipes where a vacuum adiabatic pipe is cut in a longitudinal direction under a state of storing a long member; the second cylindrical part having overlapped portions in a radial direction in respect to the first cylindrical part connected in communication with the other cut adiabatic pipe of the two cut adiabatic pipes; an insulation part integrally present at the overlapped portions of the first cylindrical part and the second cylindrical part and electrically insulating between the first cylindrical part and the second cylindrical part; the first inner pipe communication part and the first outer pipe communication part protruded out of one end part in an axial direction of the insulation part and becoming each of the communication parts of the inner pipe and the outer pipe constituting one cut adiabatic pipe; and the second inner pipe communication part and the second outer pipe communication part protruded out of the other end part in the axial direction of the insulation part and becoming each of the communication parts of the inner pipe and the outer pipe constituting the other cut adiabatic pipe.SELECTED DRAWING: Figure 1
