Embodiment Construction

[0028] Such as figure 1 As shown, the superconducting cable terminal structure of the present invention includes a terminal thermostat 100 for accommodating the superconducting cable body. The terminal thermostat is cylindrical and has four connected interface outlet pipes 104, 105, 106 and 107. , wherein, the two interface lead-out pipes 104, 105 connected with the cable body and the refrigeration system are respectively located at the two ends of the cylindrical end thermostat and are arranged in parallel with it at 180°, so as to facilitate the current leads of the conductive layer and the shielding layer (200, 300 ) with cable body 600 for installation. It can be made into an integral type, or it can also be a split type. The two interface lead-out tubes 106, 107 of the conductive layer current lead and the shielded layer current lead are vertically vertical on one side of the thermostat at the end, and the positions are respectively corresponding to the superconducting ...

Abstract

The invention discloses a superconducting cable end socket structure comprising an end socket thermostat, the end socket thermostat is provided with four communicated interface leading-out tubes, wherein two interface leading-out tubes of a cable main body and a refrigerating system are respectively located on two ends of the end socket thermostat and are arranged in parallel in 180 degrees, and two interface leading-out tubes of a conducting layer current lead and a shielding layer current lead are vertically arranged on one side edge of the end socket thermostat and are respectively corresponding to wiring positions of a superconducting conducting layer and a superconducting shielding layer of the superconducting cable main body; and the end socket thermostat is composed of an inner-layer container and an outer-layer container which are mutually sleeved, an interlayer chamber between the inner-layer container and the outer-layer container is vacuum, and a plurality layers of thermal insulating materials are wound on the interlayer chamber. Thread sealing and pressure pressing sealing ring structures are arranged at interface positions of the current lead, the end socket thermostat and an insulating element. The superconducting cable end socket structure can be used for creating a space with good thermal insulating property to guarantee reliable connection of the superconducting cable main body and meet the insulating demand.

Description

technical field [0001] The invention belongs to the application field of superconducting power technology, and in particular relates to a terminal structure connected with a three-phase split cold insulated superconducting cable body. Background technique [0002] At present, superconducting cables are divided into heat-insulated superconducting cables and cold-insulated superconducting cables according to the working temperature of the insulating layer. Among them, the structure of the cold insulated superconducting cable body is as follows Figure 4 shown. In the figure, the cold insulated superconducting cable body 600 includes, from the inside to the outside: a support tube 601 , a superconducting conductive layer 602 , an insulating layer 603 , a superconducting shielding layer 604 and the outermost protective layer. The superconducting conductive layer is connected to the grid and is at a high potential. When the superconducting conductive layer is energized, due to ...
