Abstract

The invention discloses a cooling system for a cold insulation superconducting cable. The cooling system comprises a liquid nitrogen storage tank. The cooling system is characterized by further comprising a refrigerating machine, a supercooling box, a pumpdown device and vacuum insulation liquid nitrogen pipelines. Liquid nitrogen is arranged inside the supercooling box. The temperature of the liquid nitrogen inside the supercooling box is controlled by the refrigerating machine. A liquid nitrogen pump used for supplying liquid nitrogen circulation power is connected to the supercooling box. A liquid inlet and a liquid outlet of the supercooling box are connected with the superconducting cable through the vacuum insulation liquid nitrogen pipelines. The liquid nitrogen storage tank is connected with the vacuum insulation liquid nitrogen pipeline which is connected with the liquid inlet through a pipeline in a mutual communication mode. A coiled pipe heat exchanger is arranged inside the supercooling box. The pumpdown device makes contact with the liquid nitrogen inside the supercooling box through a pipeline. A nitrogen discharge outlet is formed in the supercooling box. The cooling system for the cold insulation superconducting cable is simple in structure, convenient to use, and capable of realizing heat exchange circular integration.

Description

[0001] technical field [0002] The invention relates to a cooling system, in particular to a cooling system for cold-insulated superconducting cables. Background technique [0003] The cooling system is an important part of the superconducting cable, and the normal operation of the cooling system is a necessary condition for the grid-connected operation of the superconducting cable. The current cooling system for superconducting cables is provided separately from the subcooling box and the pump box, which takes up a lot of space, is inconvenient to use, and has high production costs. Contents of the invention [0004] In order to solve the problems in the prior art that the superconducting cable cooling system is provided separately from the subcooling box and the pump box, which occupies a large space, is inconvenient to use, and has high production costs, the present invention provides a simple structure, easy to use The cooling system of the cold insulated superconduc...
