[0027] In order to better understand the purpose, structure and function of the present invention, a high-voltage test stand of the present invention is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a high-voltage test stand of the present invention includes a base plate 5, the top of the base plate 5 is connected to the support rod 17 by bolts, the surface of the support rod 17 is provided with an external thread, the other end of the support rod 17 passes through the middle plate 3, and the other end of the support rod 17 is connected to the upper plate 2 by a thread. By installing the upper plate 2, the upper plate 2 can provide an installation position for the cylinder 1 to ensure the stability of the cylinder 1 when in use, and the stability is strong when in use. The cylinder 1 is welded on the top of the upper plate 2, and the middle plate 3 is welded at one end of the cylinder 1. A plug 10 is installed at the bottom of the middle plate 3, and a front plug 4 is installed inside the support rod 17. The front plug 4 is equidistantly distributed, and the plug 10 is equidistantly distributed. By installing the middle plate 3, when the middle plate 3 drives the plug 10 to move, the plug 10 can be pressed against the plug, so that the installation stability of the plug is strong, while improving the efficiency, and it is very convenient to use.

[0029] An air box 14 is installed on the top of the base plate 5, and the inside of the air box 14 is connected to the gas cabinet sleeve 11, and the inside of the gas cabinet sleeve 11 is sleeved with the rear plug 9. A front plug 4 is provided on the outside of the rear plug 9, and one end of the front plug 4 is connected to the gas cabinet sleeve 11. By installing the front plug 4 and the rear plug 9, when testing the plug, not only the front plug 4 but also the rear plug 9 can be tested. When testing the rear plug 9, it is necessary to first install the front plug 4 on the air box 14, and then place the rear plug 9 directly on the front plug 4 and press it tightly for testing. It is very convenient to use.

[0030] A support frame 6 is welded to the bottom of the base plate 5, and wheels 7 are installed at the bottom of the support frame 6. The wheels 7 are symmetrically distributed, and the surface of the support frame 6 is connected to the grounding wire 8. By installing the wheels 7, when the high-voltage test frame needs to be moved, the wheels 7 can be used to drive the high-voltage test frame to move, which is very convenient to use.

[0031] The gas box 14 is symmetrically distributed, and an inner cone socket 12 is installed inside the gas box 14. One end of the inner cone socket 12 is connected to the high-voltage lead rod 13. By installing the high-voltage lead rod 13, its position is outside the high-voltage test frame. At this time, it will be more convenient to perform high-voltage lead on the high-voltage lead rod 13.

[0032] An inflation nozzle 16 is provided on the surface of the gas box 14, a connecting copper busbar 15 is installed inside the gas box 14, and an inflation cabinet sleeve 11 is installed on the top of the connecting copper busbar 15.

SF6 gas has excellent insulation properties, meets the high-voltage test requirements of the plug, and ensures the accuracy of the test.

[0033] The cylinder 1 is symmetrically distributed, and the support rod 17 is symmetrically distributed. By installing the cylinder 1 in this distribution, when the cylinder 1 is used to drive the middle plate 3, a stable movement effect can be provided for the middle plate 3, and at the same time, uniform pressure can be provided, making it more stable when the plug is pressed.

[0034] The working principle of the high-voltage test stand: When using the high-voltage test stand, the plug should be inserted in the appropriate position first. At this time, the plug can be installed on the gas box 14. At this time, when testing the plug, not only the front plug 4 can be tested, but also the rear plug 9 can be tested. When testing the rear plug 9, the front plug 4 needs to be installed on the gas box 14 first, and the rear plug 9 can be directly placed on the front plug 4 for compression testing. The high-voltage test stand can test multiple plugs at a time, and is compressed by the cylinder 1. When in use, the cylinder 1 is used to drive the middle plate 3 to move, and then the plug 10 is compressed into the plug, so that the installation stability of the plug is strong, and the efficiency is improved at the same time. It is very convenient to use. The cylinder 1 is a double cylinder 1 with high pressure and good stability. It is not only efficient in testing, but also saves a lot of labor costs. Finally, SF6 gas can be filled into the gas box 14 through the inflation nozzle 16. SF6 gas has excellent insulation properties, meets the high-voltage test requirements of the plug, and ensures the accuracy of the test. The test can then be carried out.
