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.
Claims12
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, the system further comprising:
- an object to be imaged by a camera, with the object being connected to an end part of the superconducting cable within a cryostat;
- a camera installed at a site thermally insulated from the cryostat;
- with the camera being configured for imaging the object within the cryostat through a window;
- a control device that analyzes picture image data of the object acquired by the camera to detect displacement thereof;
- and
- a driving device that, on detection of the displacement of the object by the control device, causes movement of the cryostat in its entirety.
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, wherein, a pre-set sort of gas is introduced into a vacuum thermally insulating section between the inner and outer pipes of the thermally insulated double pipe to effect gas replacement to perform evacuation to vacuum, wherein, the preset sort of gas comprises a carbon oxide gas.
