Abstract

The invention discloses a superconducting cable insulating connecting pipe which comprises an inner core cylindrical liquid nitrogen circulating pipeline. A vacuum layer is arranged outside the liquid nitrogen circulating pipeline. An epoxy resin glass fiber reinforced plastic pipe is arranged outside the vacuum layer. A metal pipe is arranged outside the epoxy resin glass fiber reinforced plastic pipe. One end of the metal pipe is provided with a pipeline interface. A thermal-shrinkage high-pressure busbar insulating bush is arranged outside the metal pipe and evenly provided with a plurality of thermal-shrinkage umbrella shirts. High-potential grading rings are arranged on the two sides of each thermal-shrinkage umbrella shirt. The superconducting cable insulating connecting pipe is characterized in that the vacuum layer is filled with silica aerogel or foam glass plates, and a calcium silicate heat insulating layer is further arranged between the epoxy resin glass fiber reinforced plastic pipe and the metal pipe. It is ensured that less heat leaks when low-temperature cooling medium liquid nitrogen passes through the pipe; furthermore, overall use performance is improved.

Description

technical field [0001] The invention relates to a superconducting cable insulating connecting pipe. Background technique [0002] Since the thermostat at the end of the insulated superconducting cable at room temperature is at a high potential and the supporting cooling system is at a low potential, the two need to be connected through a superconducting cable insulating connecting tube. The superconducting cable insulating connecting tube realizes electrical insulation and also has The adiabatic liquid nitrogen flows to the channel, but when the liquid nitrogen flows, some heat still leaks out, which cannot achieve the desired effect. Contents of the invention [0003] In view of the above problems, the present invention provides an insulated connecting pipe for superconducting cables, which ensures little heat leakage when the low-temperature cooling medium liquid nitrogen passes through. [0004] In order to achieve the above-mentioned technical purpose and achieve the ...
