Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a portable AC resonant withstand voltage auxiliary insulation bracket. Background Technology

[0002] During routine AC resonant withstand voltage tests, the insulation level between the reactor base and the ground often fails to meet standards due to the complex on-site testing environment, leading to discharge between the reactor base and the ground. If this discharge occurs during the AC resonant withstand voltage test, it can easily damage both the tested equipment and the testing equipment. Furthermore, in complex on-site testing environments, the reactor placement can easily cause it to tilt and slide, affecting the subsequent stacking and use of reactors. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a portable AC resonant withstand voltage auxiliary insulation bracket, which allows the reactor base to be placed horizontally and stably, thereby making the stacked reactors more stable and improving the safety and controllability of AC resonant withstand voltage.

[0004] The present invention adopts the following technical solution:

[0005] A portable AC resonant withstand voltage auxiliary insulating bracket includes an insulating plate, an insulating support frame, an insulating clamp plate one, and an insulating clamp plate two. The insulating support frame and the insulating clamp plate one are connected by two insulating slide rods, which pass through the insulating clamp plate two. The insulating clamp plate two is located between the insulating support frame and the insulating clamp plate one. One end of the insulating drive rod is installed at the insulating support frame, and the other end of the insulating drive rod is threaded to the insulating clamp plate two. A transmission gear is installed on one side of the insulating drive rod inside the insulating support frame. The transmission gear meshes with the drive gear, which is installed at the insulating support frame. The lower ends of the insulating support frame and the insulating clamp plate one are respectively installed on the insulating drive rod. The bottom of the insulating drive rod is installed on an insulating base plate. The insulating plate is fitted onto the insulating drive rod, and the bottom of the insulating plate rests on an insulating knob. The insulating knob is threaded to the insulating drive rod.

[0006] Furthermore, four wheels and four adjustable support feet are installed at the lower end of the insulating base plate.

[0007] Furthermore, two adapter shafts are installed at the insulating support frame, and transmission gears are installed on the adapter shafts. These transmission gears mesh with transmission gears mounted on the insulating drive rod and with the drive gear.

[0008] Furthermore, the drive gear is mounted on the drive shaft, which is located between two adapter shafts. Both the drive gear and the transmission gear are located within an insulated support frame.

[0009] Furthermore, the end of the drive shaft passes through the outside of the insulating support frame, and the end cross-section of the drive shaft is polygonal.

[0010] Furthermore, a crank mounting bracket is installed on one side of the insulating plate, on which a crank is placed, and the crank is connected to the end of the drive shaft.

[0011] Furthermore, two tie rod mounting plates are installed on one side of the insulating base plate, and a tie rod mounting shaft is installed between the two tie rod mounting plates. The bottom of the tie rod is installed on the tie rod mounting shaft.

[0012] Beneficial effects

[0013] This invention can ensure personnel safety by fixing and leveling the reactor base through insulating clamp one and insulating clamp two, preventing the reactor base from shaking and tilting, making the subsequent stacking of reactors more stable, and to a certain extent reducing the probability of tipping accidents after stacking reactors, thus ensuring the safety of test personnel.

[0014] Protecting test equipment: The insulating board enhances the insulation level of the reactor base, preventing the reactor base from discharging to ground due to a decrease in insulation level caused by environmental issues, which could lead to withstand voltage failure and affect the safety of the withstand voltage device and the equipment being withstand voltage.

[0015] Enhanced test controllability: The application of this utility model makes the test process more rigorous, avoids test errors caused by environmental factors, and improves the standardization and controllability of the entire test process. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] As shown in the figure, this utility model discloses a portable AC resonant withstand voltage auxiliary insulating bracket, including an insulating plate 1, an insulating support frame 2, an insulating clamp 3, and an insulating clamp 4. The insulating support frame 2 and the insulating clamp 3 are connected by two insulating slide rods 5, which pass through the insulating clamp 4. The insulating clamp 4 is located between the insulating support frame 2 and the insulating clamp 3. One end of the insulating drive rod 6 is installed at the insulating support frame 2, and the other side of the insulating drive rod 6 is threadedly connected to the insulating clamp 4. A transmission gear 7 is installed on one side of the insulating drive rod 6 inside the insulating support frame 2. The transmission gear 7 meshes with a drive gear 8, which is installed at the insulating support frame 2. The lower ends of the insulating support frame 2 and the insulating clamp 3 are respectively installed on the insulating drive rod 9. The bottom of the insulating drive rod 9 is installed on the insulating base plate 10. The insulating plate 1 is sleeved on the insulating drive rod 9, and the bottom of the insulating plate 1 rests on the insulating knob 11. The insulating knob 11 is threadedly connected to the insulating drive rod 9.

[0020] The drive gear 8 drives the transmission gear 7 to rotate, which in turn drives the insulating drive rod 6 to rotate. Then, it drives the insulating clamp 4 to move horizontally. The insulating clamp 4 moves along the insulating slide rod 5, ensuring that the insulating clamp 4 can move horizontally and linearly, so as to combine with the insulating clamp 3 to clamp the reactor base.

[0021] The insulating plate 1 is used to place the reactor. By adjusting the four insulating knobs 11, the insulating plate 1 is ensured to be in a horizontal position. Adjusting the position of the insulating plate 1 ensures that the reactor base is placed at a height that meets the withstand voltage requirements.

[0022] In one embodiment of this utility model, four wheels 12 and four adjustable support feet 13 are installed at the lower end of the insulating base plate 10.

[0023] In use, according to the requirements of the AC resonant withstand voltage test, place this utility model in the designated position, release the brake on wheel 12 to fix wheel 12, and then operate the adjustable support foot 13 to place the portable AC resonant withstand voltage auxiliary insulating bracket horizontally. Of course, other telescopic devices can also be used to adjust the support foot 13 to achieve a horizontal position.

[0024] In one embodiment of this utility model, two adapter shafts 14 are installed at the insulating support frame 2, and transmission gears 7 are installed on the adapter shafts 14. The transmission gears 7 here mesh with transmission gears 7 installed on the insulating drive rod 6, and also mesh with drive gears 8. Here, by driving the drive gears 8, through gear transmission, the drive gears 8 drive the transmission gears 7 to rotate, and the transmission gears 7 drive the insulating drive rod 6 to rotate, thereby driving the insulating clamp 2 4 to move horizontally.

[0025] In one embodiment of this utility model, the drive gear 8 is mounted on the drive shaft 15, which is located between two adapter shafts 14. Both the drive gear 8 and the transmission gear 7 are located within the insulating support frame 2. The drive shaft 15 rotates, thereby driving the drive gear 8 to rotate.

[0026] In one embodiment of this utility model, the end of the drive shaft 15 passes through the outside of the insulating support frame 2, and the end cross-section of the drive shaft 15 is polygonal. This allows the drive shaft 15 to be manually rotated using a crank handle 17.

[0027] In one embodiment of this utility model, a crank mounting bracket 16 is installed on one side of the insulating plate 1, and a crank 17 is placed on the crank mounting bracket 16. The crank 17 is connected to the end of the drive shaft 15. The crank 17 is used to drive the drive shaft 15 to rotate, thereby driving the drive gear 8 to rotate.

[0028] Depending on the size of the reactor, crank 17 is used to move the insulating clamp 4 along the insulating slide bar 5, thereby fixing the reactor base with insulating clamp 3 and insulating clamp 4. Then, the grounding point A of this invention is connected to a reliable grounding point, and the test begins and continues until the end of the test.

[0029] In one embodiment of this utility model, two tie rod mounting plates 18 are installed on one side of the insulating base plate 10, and a tie rod mounting shaft 19 is installed between the two tie rod mounting plates 18. The bottom of the tie rod 20 is mounted on the tie rod mounting shaft 19. The tie rod 20 is telescopic and is used to move this utility model.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
