Title:
SUPERCONDUCTIVE CABLE TRAM WAY
Document Type and Number:
Japanese Patent JP2020087878
Kind Code:
A
Abstract:
To provide a superconductive cable tram way capable of suppressing pressure increase with volume expansion of a liquid coolant without releasing the liquid coolant to outside.SOLUTION: There is provided a superconductive cable tram way having a superconductive cable having a conductor part with a superconductive conductor layer and a heat insulation tube including a coolant flow passage for cooling the conductor part, and a container communicating with the coolant flow passage and having a gas phase and a liquid phase in a series with the liquid coolant, in which the gas phase has initial volume Vsatisfying P≤P, in which expansion amount when the liquid coolant in the coolant flow passage has volume expansion is ΔV, acceptable pressure is Pin the container and pressure after the liquid phase increases with the expansion amount ΔV is P.SELECTED DRAWING: Figure 1
