The two ends of the third spring 53 are respectively connected to the pull tab 51 and the side tube 49. A second positioning rod 52 is connected to the pull tab 51. Positioning tubes 54 are installed at both ends of the second guardrail 10. In the initial state, the first rotating plate 4 is laid flat on the ground. Both the first guardrail 6 and the second guardrail 10 are in a vertical state. The supporting seat 29 and the hanging plate 32 at one end of the reinforcing plate 28 are fastened to the corresponding positions on the first guardrail 6 to ensure that the first guardrail 6 is in a vertical state. The second positioning rod 52 on the pull tab 51 is inserted into the second side tube 49. The positioning cylinder 54 at the end of the guardrail 10 keeps the second guardrail 10 in a vertical position. This, using two sets of first guardrails 6 and second guardrails 10, provides safety protection around the transformer body 1. When maintenance is needed on components of the transformer body 1, and due to the large size of the transformer, support tools are required, firstly, the pull tab 51 is used to pull the second positioning rod 52 out of the positioning cylinder 54 at the end of the second guardrail 10, releasing the connection between the first guardrail 6 and the second guardrail 10. Next, with the first rotating shaft 3 as the axis, the first rotating plate 4 is rotated from the ground, and the moving cylinder 24 is pulled on the fixed cylinder 22, pulling one end of the first positioning rod 25 out of the second positioning hole 26 of the positioning plate 27. 4. Release the positioning of the insert plate 11, then rotate the insert plate 11 out from the storage slot 16 and opening 17. Next, move the sleeve 12 on the insert plate 11 to lower the support plate 13 to support it on the ground. Then, rotate one end of the first screw 18 into the corresponding first positioning hole 21 on the insert plate 11 through the first rotating ring 20. Position the sleeve 12 and support plate 13 as a whole on the insert plate 11. Then, use the second rotating ring 34 to rotate one end of the second screw 33 out from the threaded groove on the lifting seat 29. Then, rotate the hanging plate 32 on the lifting seat 29 to remove the lifting seat 29 and the hanging plate 32 from the first guardrail 6. Then, rotate the first guardrail 6 to a horizontal state with the first rotating shaft 3 as the axis towards the transformer body 1. Then, reposition the support plate 18. The support 29 is positioned on the corresponding position of the first guardrail 6. The hanging plate 32 is rotated in the opposite direction on the support 29, and one end of the second screw 33 is turned into the threaded groove on the support 29. The reinforcing plate 28 is used to stabilize the first guardrail 6 after it has been turned flat. Then, the second rotating plate 9 is rotated with the second rotating shaft 8 as the axis, and the second guardrail 10 is turned flat with the second crossbar 44 as the axis. The third screw is rotated with the rotating block 37 on the through plate 35. The positioning plate 36 moves into the positioning groove 38 on the side of the second guardrail 10 to position the second guardrail 10 after it has been turned flat. In this way, maintenance personnel can stand directly on the first guardrail 6 or the second guardrail 10, which greatly facilitates the maintenance work of the transformer body 1.

[0045] See Figures 2-4The access structure includes an entrance 39 on one of the first guardrails 6, a fifth rotating shaft 42 rotatably connected between the two side walls of the entrance 39, a sleeve 43 fixedly sleeved on the fifth rotating shaft 42, an entrance 40 installed on the sleeve 43, multiple climbing poles 41 connected at equal intervals between the inner walls of the entrance 40, and a fourth positioning structure between the entrance 40 and the first guardrail 6.

[0046] The fourth positioning structure includes a fourth screw 45 rotatably mounted on the first guardrail 6. One end of the fourth screw 45 is inserted into a threaded groove on the access door 40. A third rotating ring 47 is provided at one end of the fourth screw 45. A fixing ring 46 is fixedly sleeved on the fourth screw 45. A second spring 48 is sleeved on the fourth screw 45. The two ends of the second spring 48 are respectively connected to the fixing ring 46 and the access door 40. When the first guardrail 6 and the second guardrail 10 are in a vertical state for safety protection, the access door 40 can be opened at the entrance 39 to facilitate the entry and exit of maintenance personnel. When the first guardrail 6 and the second guardrail 10 are in a horizontal state to assist the work of maintenance personnel, the access door 40 can be opened at the entrance 39 to support one end of the access door 40 to the ground. In this way, the access door 40 and the climbing pole 41 can be used as a ladder to facilitate the movement of maintenance personnel to the first guardrail 6 and the second guardrail 10 for work. The structure is simple and the function is practical.

[0047] The implementation principle of a low-noise, fully insulated ultra-high voltage transformer according to an embodiment of the present invention is as follows: In the initial state, the first rotating plate 4 is laid flat on the ground, and both the first protective railing 6 and the second protective railing 10 are in a vertical state. The supporting seat 29 at one end of the reinforcing plate 28 and the hanging plate 32 are fastened to the corresponding position on the first protective railing 6, ensuring that the first protective railing 6 is in a vertical state. Furthermore, the second positioning rod 52 on the pull-out piece 51 is inserted into the positioning cylinder 54 at the end of the second protective railing 10, making the second protective railing 10 in a vertical state. Thus, using two sets of first protective railings 6 and second protective railings 10, safety protection is provided around the transformer body 1. When it is necessary to inspect the transformer body 1... When repairing the upper parts, due to the large size of the transformer, support tools are needed. First, use the pull tab 51 to pull the second positioning rod 52 out of the positioning cylinder 54 at the end of the second guardrail 10, releasing the connection between the first guardrail 6 and the second guardrail 10. Next, using the first rotating shaft 3 as the axis, rotate the first rotating plate 4 from the ground, and pull the moving cylinder 24 on the fixed cylinder 22 to pull one end of the first positioning rod 25 out of the second positioning hole 26 of the positioning plate 27, releasing the positioning of the insert plate 11 on the first rotating plate 4. Then, rotate the insert plate 11 out from the storage slot 16 and the opening 17. Next, move the sleeve 12 on the insert plate 11 to support the... The plate 13 is lowered and supported on the ground. The first screw 18 is rotated into the first positioning hole 21 on the insert plate 11 via the first rotating ring 20, positioning the sleeve 12 and support plate 13 as a whole on the insert plate 11. Then, the second screw 33 is rotated out of the threaded groove on the lifting seat 29 using the second rotating ring 34. The hanging plate 32 is then rotated on the lifting seat 29 to remove the lifting seat 29 and hanging plate 32 from the first guardrail 6. The first guardrail 6 is then rotated to a horizontal position towards the transformer body 1, with the first rotating shaft 3 as the axis. The lifting seat 29 is then repositioned on the first guardrail 6 to the corresponding position. The hanging plate 32 is rotated in the opposite direction, and one end of the second screw 33 is turned into the threaded groove on the support seat 29. The first guardrail 6 after being turned flat is stably supported by the reinforcing plate 28. Then, the second rotating plate 9 is rotated with the second rotating shaft 8 as the axis, and the second guardrail 10 is turned flat with the second crossbar 44 as the axis. The third screw is rotated by the rotating block 37 in the through plate 35. The positioning plate 36 moves into the positioning groove 38 on the side of the second guardrail 10 in the through plate 35 to position the second guardrail 10 after being turned flat. In this way, maintenance personnel can stand directly on the first guardrail 6 or the second guardrail 10, which greatly facilitates the maintenance work of the transformer body 1.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
