[0019] Example 1.

[0020] Preferably, the superconducting cable high-voltage terminal is plugged into the superconducting cable 400, and the superconducting cable high-voltage terminal includes:

[0021] The input end 100 includes (1) a first insulating sheet 110 and (1) a first insulating sleeve 120. The first insulating sheet 110 has a first insulating sheet contraction end 111 and a first insulating sheet open end 112. The first insulating sheet contraction end 111 is connected to a second insulating sleeve 220 of an adjacent main section insulating structure 201 (located in the main section 200); so as to improve the insulation performance of the main section 200 and the input end 100 adjacent thereto. One end of the first insulating sleeve 120 is inscribed in the first insulating sheet contraction end 111, and the other end of the first insulating sleeve 120 is connected to an elastic sealing structure 130. Since the superconducting cable 400 is inserted into the input end 100 through the elastic sealing structure 130, the other end of the first insulating sleeve 120 is connected to the elastic sealing structure 130, which can improve the sealing performance of the input end 100 and the superconducting cable 400 adjacent thereto, and prevent dust and other impurities, rainwater and other liquids from penetrating into the input end 100 and causing safety hazards.

[0022] The main body section 200 includes a plurality of adjacent main body section insulation structures 201; the main body section 200 is divided into a plurality of adjacent main body section insulation structures 201, thereby improving the overall safety of the superconducting cable high-voltage terminal; each main body section insulation structure 201 includes (1) second insulation sheet 210 and (1) second insulation sleeve 220, the second insulation sheet 210 has a second insulation sheet contraction end 211 and a second insulation sheet open end 212, one end of the second insulation sleeve 220 is internally connected to the second insulation sheet contraction end 211 of the same main body section insulation structure 201, and the other end of the second insulation sleeve 220 is externally connected to the second insulation sheet contraction end 211 of the adjacent main body section insulation structure 201; the adjacent main body section insulation structures 201 are kept relatively independent while emphasizing the insulation performance, thereby preventing the occurrence of local areas with weak insulation performance.

[0023] Among them, the elastic sealing structure 130 includes a first elastic sealing ring 131 and a second elastic sealing ring 132 connected to the first elastic sealing ring 131, the inner diameter of the first elastic sealing ring 131 is larger than the inner diameter of the second elastic sealing ring 132, the first elastic sealing ring 131 is in contact with the first insulating sleeve 120, and the second elastic sealing ring 132 is in contact with the superconducting cable 400, thereby improving the sealing performance of the adjacent part of the input end 100 and the superconducting cable 400, preventing impurities such as dust and liquids such as rainwater from penetrating into the input end 100 and causing safety hazards.

[0024] Among them, the input end 100 also includes a clamp structure 140, which is externally placed on the elastic sealing structure 130, and the clamp structure 140 includes a clamp ring 141 and a buckle 142 movably connected to the clamp ring 141; the position of the elastic sealing structure 130 is fixed by the clamp structure 140 to prevent the elastic sealing structure 130 from being displaced, thereby keeping the relative position between the superconducting cable 400 and the input end 100 fixed, which facilitates external equipment to test the electrical performance of the superconducting cable 400.

[0025] The superconducting cable high-voltage terminal further comprises an extension end 300, which comprises an extension column 310 and a vertical plate 320 fixedly connected to the extension column 310, and two sides of the vertical plate 320 are respectively provided with (1) connecting bolt 330, so as to facilitate the external connection of the superconducting cable high-voltage terminal to a desired position. As an example, a device for testing electrical properties such as voltage.

[0026] Among them, the number of the main body segment insulation structures 201 of the main body segment 200 is preferably 7.

[0027] It is worth mentioning that the superconducting cable high-voltage terminal disclosed in the utility model adopts multiple means to improve the insulation performance both in the overall and local aspects. At the same time, the relative position between the superconducting cable 400 and the input terminal 100 remains fixed, which facilitates the electrical performance test of the superconducting cable 400 by external equipment, such as high-voltage performance test (those skilled in the art know that high-voltage test is one of the important electrical performance tests of superconducting cables).

[0028] It should be noted that the superconducting cable high-voltage terminal disclosed in the present utility model does not provide the electrical performance test function of the superconducting cable 400 itself, but provides the necessary test environment for the electrical performance test function of the superconducting cable 400 without destroying the electrical performance of the superconducting cable 400 itself.

[0029] It is worth mentioning that the technical features such as the material of the first insulating sheet 110 involved in the utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field and should not be regarded as the inventive point of the utility model patent.
