Abstract
In a thermally insulated double pipe, a structure is provided in which an inner pipe may be prevented from being appreciably offset relative to an outer pipe due to thermal contraction. The structure includes an inner pipe 101, within which a superconducting cable is mounted, an outer pipe 103 within which the inner pipe is housed, with the inner and outer pipes constituting a thermally insulated double pipe, and an inner pipe support member 104 supporting the inner pipe. The inner pipe support member 104 is secured to the inner and outer pipes.
Claims18
A superconducting power transmission system, comprising:
- a thermally insulated double pipe composed by an inner pipe within which a superconducting cable is installed and by an outer pipe within which the inner pipe is housed;
- and
- an inner pipe support member(s) supporting the inner pipe;
- the inner pipe support member(s) being secured to the inner and outer pipes.
A method for evacuation to vacuum for a thermally insulated double pipe, comprising:
- introducing a pre-set sort of gas into a region defined between an inner pipe and an outer pipe composing a thermally insulated double pipe, thereby effecting gas replacement, with a superconducting cable being installed within the inner pipe, with the inner pipe being housed within the outer pipe;
- evacuating said region to vacuum;
- and
- subsequently cooling the inner pipe.
