Description

Technical Field

[0001] This invention belongs to the technical field of cable connection devices, specifically a cable terminal connection device for GIS and GIS. Background Technology

[0002] With the rapid development of power grid construction, the demand for power cable GIS terminals is also increasing rapidly. GIS cable terminal connection devices are essential devices used to connect power cables and the GIS body.

[0003] Existing GIS cable termination connection devices require separate withstand voltage tests on both the GIS body and the power cable due to inconsistencies in their field withstand voltage test parameters. During testing, the GIS body must first be connected via a withstand voltage sleeve and conductive rod, and then tested. After testing, the withstand voltage sleeve and conductive rod must be removed, and the GIS body reconnected to the power cable for testing. If the test data are consistent, the withstand voltage sleeve and conductive rod must be removed again, and the GIS body reconnected to the power cable. This process is extremely cumbersome and significantly increases the workload for staff.

Detailed Implementation

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] Example 1:

[0028] like Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides a cable terminal connection device for GIS. This cable terminal connection device includes a detection unit 3 for detecting objects, including a pressure-resistant sleeve 31 for high voltage resistance and an adjusting member 32 for adjusting the contact between the GIS body 21, the power cable 22 and the conductive rod 311. The pressure-resistant sleeve 31 is located at one end inside the second connecting cylinder 12 and is snapped into the second connecting cylinder 12. The adjusting member 32 is located at the connection between the first connecting cylinder 11 and the second connecting cylinder 12.

[0029] Furthermore, one end of the pressure-resistant sleeve 31 is provided with a conductive rod 311 for contacting the contact rod 327. One end of the conductive rod 311 horizontally penetrates the pressure-resistant sleeve 31, and the conductive rod 311 extends to the other end of the pressure-resistant sleeve 31. The adjusting member 32 includes a "T-shaped block" 321 that drives the second contact head 324 to rotate. The "T-shaped block" 321 has receiving grooves 322 on three sides for accommodating the second elastic member 323 and the second contact head 324. The receiving groove 322 is provided with a second elastic member 323 for pushing the second contact head 324 to move and a second contact head 324 for contacting the first contact head 23. One end of the second elastic member 323 is fixedly connected to the inner wall of the receiving groove 322, and the other end of the second elastic member 323 is fixedly connected to the second contact head 324. The second contact heads 324 on both sides of the "T-shaped block" 321 respectively contact the symmetrically arranged first contact heads 23.

[0030] Furthermore, the "T-shaped block" 321 is also horizontally provided with a receiving hole 325 for accommodating the contact rod 327. A sleeve 326 for accommodating the contact rod 327 is provided on one side of the receiving hole 325. The sleeve 326 is fixedly connected to the "T-shaped block" 321. The receiving hole 325 communicates with the interior of the sleeve 326. The sleeve 326 is internally threaded with a contact rod 327 for contacting the conductive rod 311. One end of the contact rod 327 extends into the receiving hole 325, and the other end of the contact rod 327 extends out of the sleeve 326. A rotating rod 328 for driving the sleeve 326 to rotate is fixedly connected to the sleeve 326. The rotating rod 328 is located at the other end of the second connecting cylinder 12 and is rotatably connected to the second connecting cylinder 12. The cable terminal connection device is the GIS cable terminal connection device described above.

[0031] It should be noted that the sleeve 326 and the rotating rod 328 are made of high-voltage resistant insulating material, and the contact rod 327 extending from one end of the sleeve 326 is coated with an insulating layer.

[0032] Operation process: When it is necessary to connect the GIS body 21 to the power cable 22, since the on-site withstand voltage test parameters of the GIS body 21 and the power cable 22 are inconsistent, it is necessary to conduct withstand voltage tests on both separately. First, the GIS body 21 is inserted from the upper end of the first connecting cylinder 11. By rotating the rotating rod 328 clockwise by 90°, the rotating rod 328 drives the sleeve 326 to rotate. Since the sleeve 326 is fixedly connected to the "T-block" 321, the "T-block" 321 rotates with the sleeve 326. While the "T-block" 321 rotates 90° clockwise, one side of the second contact head 324 set on the three sides of the "T-block" 321 contacts the upper contact head of the first contact head 23 symmetrically set inside the first connecting cylinder 11. Then, by rotating the contact rod 327, the contact rod 327 moves to the left along the direction of the sleeve 326, so that the contact rod 327 moves to contact the conductive rod 311.

[0033] Furthermore, when the contact rod 327 contacts the conductive rod 311, the conductive rod 311 forms a circuit through the contact rod 327, the second contact head 324, the "T-block" 321, and the lower contact head of the first contact head 23, thereby performing a withstand voltage test on the GIS body 21. After the test is completed, the rotating rod 328 is rotated 180° counterclockwise, so that one side of the second contact head 324 arranged on the three sides of the "T-block" 321 contacts the lower contact head of the first contact head 23 symmetrically arranged inside the first connecting cylinder 11. Then, the power cable 22 is inserted from the lower end of the first connecting cylinder 11. At this time, the conductive rod 311 forms a circuit through the contact rod 327, the second contact head 324, the "T-block" 321, and the upper contact head of the first contact head 23, thereby performing a withstand voltage test on the power cable 22.

[0034] Furthermore, when the withstand voltage test results are consistent, the contact rod 327 can be rotated in the opposite direction to move it to the right along the sleeve 326, separating the contact rod 327 from the conductive rod 311. Finally, the rotating rod 328 is rotated 90° clockwise so that the second contact head 324 on the three sides of the "T-block" 321 contacts the upper and lower contact heads of the first contact head 23 on both sides, thereby completing the connection between the GIS body 21 and the power cable 22.

[0035] Example 2:

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment differs from the first embodiment in that: the cylindrical body 1 for containing the object includes a first connecting cylinder 11 for installing the GIS body 21 and the power cable 22 and a second connecting cylinder 12 for installing the pressure-resistant sleeve 31. The first connecting cylinder 11 and the second connecting cylinder 12 are arranged perpendicularly to each other and are internally connected. The connecting unit 2 includes the GIS body 21 and the power cable 22, which are located at the top and bottom ends of the first connecting cylinder 11, respectively.

[0037] Furthermore, the top and bottom ends of the inner wall of the first connecting cylinder 11 are symmetrically and vertically provided with a first groove 13 and a second groove 14 to facilitate the sliding of the first slider 211 and the second slider 221. A connecting groove 15 is provided between the first groove 13 and the second groove 14. The length of the first groove 13 is less than the length of the second groove 14. The GIS body 21 includes a first slider 211 located in the first groove 13 at the top end of the inner wall of the first connecting cylinder 11 to facilitate the movement of the GIS body 21. The first slider 211 is fixedly connected to the GIS body 21. The power cable 22 includes a second slider 221 located in the first groove 13 at the bottom end of the inner wall of the first connecting cylinder 11 to facilitate the movement of the power cable 22. The second slider 221 is fixedly connected to the power cable 22.

[0038] It should be noted that the inner walls of both the first connecting cylinder 11 and the second connecting cylinder 12 are coated with an insulating layer.

[0039] Operation process: By pushing the first slider 211 fixedly connected to the GIS body 21 and the second slider 221 fixedly connected to the power cable 22 along the direction of the second slide groove 14, when pushed to a certain extent, the GIS body 21 and the power cable 22 respectively come into contact with the first elastic element 24 provided on one side of the symmetrically arranged first contact head 23. When the GIS body 21 and the power cable 22 are pushed further, the first elastic element 24 undergoes elastic deformation, pushing the first slider 211 and the second slider 221 from the second slide groove 14 into the connecting groove 15. By rotating the GIS body 21 and the power cable 22, the first slider 211 and the second slider 221 move from one end of the connecting groove 15 to the other end of the connecting groove 15. At this time, the GIS body 21 and the power cable 22 are released, the first elastic element 24 is no longer under force, and the first elastic element 24 elastically resets, pushing the first slider 211 and the second slider 221 into the first slide groove 13, thereby completing the rapid installation of the GIS body 21 and the power cable 22 with the first connecting cylinder 11.
