[0018] See Figure 1-2 A high-voltage capacitor testing device includes a base 1, on which multiple lifting cylinders 2 are arranged, and a base plate 3 is provided at the end of the piston rod of the lifting cylinder 2; columns 4 are provided at the four corners of the base 1, and the same mounting plate 5 is provided on the top of the columns 4; a partition 6 is provided at the center of the lower part of the mounting plate 5, and the partition 6 is arranged along the length of the mounting plate 5; metal plates 7 are provided on the left and right sides of the mounting plate 5, and each metal plate 7 is equipped with a metal pressure plate 8; the metal pressure plates 8 are symmetrically arranged; wire clamp fixing posts 9 and multiple connecting rods 10 are respectively provided on the outer side of the metal pressure plates 8; the connecting rods 10 penetrate the mounting plate 5; a push cylinder 11 is provided on the mounting plate 5, and the end of the piston rod of the push cylinder 11 is fixedly connected to the connecting rod 10; a limiting groove 12 for the movement of the connecting rod is opened on the mounting plate 5. Specifically, high-voltage capacitors are placed equidistantly on substrate 3 with their leads in a vertical position. Lifting cylinder 2 is activated to raise the high-voltage capacitors, positioning the leads between the metal plates 7 and metal pressure plates 8 on the left and right sides. Then, pushing cylinder 11 is activated to push the metal pressure plates 8 towards the metal plates 7, clamping the leads between the metal plates 7 and metal pressure plates 8. The two wire clamp fixing posts 9 on the left and right sides are respectively connected to the positive and negative power supply wire clamps of the power supply equipment. Voltage is transmitted to both ends of the high-voltage capacitors through the wire clamp fixing posts 9, metal plates 7, and metal pressure plates 8, and applied to the high-voltage capacitors, enabling multiple high-voltage capacitors to undergo withstand voltage testing simultaneously, thereby improving testing efficiency. Lifting cylinder 2 is preferably an electric cylinder, which can adjust the lifting height to accommodate high-voltage capacitors of different heights.
[0019] In this embodiment, multiple positioning slots 13 are equally spaced on the substrate 3. High-voltage capacitors are placed within the positioning slots 13, allowing them to be arranged at equal intervals, which facilitates testing.
[0020] In this embodiment, the substrate 3, mounting plate 5, partition plate 6, and connecting rod 10 are all made of epoxy glass cloth laminate. The substrate 3, mounting plate 5, partition plate 6, and connecting rod 10 are all insulating materials, which improves insulation and avoids adverse effects on the high-voltage capacitor during testing.
[0021] In this embodiment, a telescopic guide post 14 is provided on the base 1, and the top of the telescopic guide post 14 is connected to the substrate 3. The telescopic guide post 14 improves the stability of lifting and lowering the substrate 3, thereby facilitating the lifting and lowering of the high-voltage capacitor.
[0022] In this embodiment, the two sides each have at least three propulsion cylinders 11, which are equidistantly distributed and can apply force evenly to the metal pressure plate 8 through the connecting rod 10, so as to ensure that the metal pressure plate 8 can fit with the metal plate 7.
