Description

Technical Field

[0001] The utility model relates to the technical field of capacitor withstand voltage testing equipment, in particular to a capacitor withstand voltage testing device. Background Technique

[0002] The withstand voltage of a capacitor is one of the important indicators to measure its performance, which is related to the stability and reliability of the capacitor in a high-voltage environment and is crucial for ensuring the safe and stable operation of the entire power electronics system;

[0003] However, the existing testing devices can only test a single capacitor at a time. When facing large-scale production or batch detection, this will undoubtedly greatly increase the testing time and cost and reduce the overall production efficiency; and during the testing process, it is usually necessary to use copper sheets to contact the pins of the capacitor to complete the testing. However, as the number of tests increases, the elasticity of the copper sheets will gradually decrease, and their surfaces will also oxidize due to frequent contact with the pins, resulting in poor contact, which will affect the accuracy of the test results and greatly reduce the reference value of the test results. Summary of the Utility Model

[0004] A capacitor withstand voltage testing device proposed by the utility model solves the existing problems.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A capacitor withstand voltage testing device includes a control console, a moving sliding table is connected to the upper end of the control console, and the moving sliding table is a threaded rotation and movement structure. A fixing mechanism is connected above the moving sliding table, the fixing mechanism is used for stably placing the capacitor, a pin is connected to the middle of the upper end of the fixing mechanism, a testing mechanism is connected above the pin, and a pressing mechanism is connected to one end above the control console, and the testing mechanism is connected below the middle of the pressing mechanism.

[0006] Preferably, the moving sliding table includes a bottom plate, and strip blocks are respectively connected to both sides above the bottom plate. A clamping strip is connected above the two strip blocks, and rectangular grooves are opened on both sides of the upper end of the clamping strip.

[0007] Preferably, a lead screw is connected to the middle of the upper side of the bottom plate, and a motor is connected to one end of the lead screw. An arc seat is arranged outside the lead screw, a substrate is connected above the arc seat, and tooth blocks are connected to both sides below the substrate, and the tooth blocks are matched with the clamping strip.

[0008] Preferably, the fixing mechanism includes a box body, a groove is opened inside the box body, an extension block is connected to the inner wall of the upper end of the box body, through holes are opened on both sides of the box body, guard plates are connected to both sides of the box body corresponding to the through holes, and a bidirectional threaded rod is connected inside the guard plates.

[0009] Preferably, two moving rods are respectively connected to both outer ends of the bidirectional threaded rod. A fixing plate is connected to the opposite sides of the two moving rods. A sealing plate is connected above the extension block. Fixed cylinders are connected to the four corners of the box body, and a clamping block is connected to the outside of the cylinder.

[0010] Preferably, the testing mechanism includes a contact member. A square plate is connected to the outer end of the contact member. A power distribution box is arranged above the square plate, and a high-voltage power line is connected to one side of the power distribution box.

[0011] Preferably, the pressing mechanism includes a column. A cover plate is connected to the upper end of the column, and cylinders are symmetrically connected to the middle of the cover plate. A pushing frame is connected below the cylinders.

[0012] The beneficial effects of the present utility model are as follows: The device places multiple capacitors in the box body at the same time. By rotating the bidirectional threaded rod, the moving rods at both outer ends drive the fixing plate to fix the capacitors, enabling the simultaneous testing of multiple capacitors and improving the testing efficiency. Rotating the screw rod makes the arc seat drive the fixing mechanism to move. Cooperating with the cylinder to push the square plate downwards, the contact member contacts the pin connected to the upper end of the fixing mechanism, and the high-voltage power supply applies voltage to the capacitor to be tested through the pin, changing the original elastic contact mechanism and avoiding the problem of inaccurate testing caused by poor contact.

And a pressing mechanism 6 is connected to one end above the console 1. The testing mechanism 5 is connected below the middle of the pressing mechanism 6.

[0021] Refer to Figure 2 , the moving slide 2 includes a bottom plate 201, and strip blocks 202 are respectively connected to both sides above the bottom plate 201. A clamping strip 203 is connected above the two strip blocks 202. Rectangular grooves are opened on both sides of the upper end of the clamping strip 203. A lead screw 204 is connected to the middle of the upper side of the bottom plate 201. And a motor 205 is connected to one end of the lead screw 204. An arc seat 206 is arranged outside the lead screw 204. A substrate 207 is connected above the arc seat 206. And tooth blocks 208 are connected to both sides below the substrate 207. The tooth blocks 208 are matched with the clamping strip 203. By rotating the lead screw 204, the arc seat 206 at the outer end of the lead screw 204 drives the substrate 207 to move, and the tooth blocks 208 on both sides of the lower end of the substrate 207 slide on the outer end of the clamping strip 203, so that the fixing mechanism 3 on the upper end of the substrate 207 can move smoothly.

[0022] Refer to Figure 3 , the fixing mechanism 3 includes a box body 301, and a groove is opened inside the box body 301. An extension block 302 is connected to the inner wall of the upper end of the box body 301. Through holes are opened on both sides of the box body 301. Protective plates 303 are connected to both sides of the box body 301 corresponding to the through holes. And a bidirectional threaded rod 304 is connected inside the protective plates 303. Two moving rods 305 are respectively connected to both ends of the outer side of the bidirectional threaded rod 304. A fixing plate 306 is connected to the opposite side of the two moving rods 305. A sealing plate 307 is connected above the extension block 302. Fixed cylinders are connected to the four corners of the box body 301, and clamping blocks 308 are connected to the outside of the cylinders. Place the capacitor to be detected inside the box body 301, and rotate the bidirectional threaded rod 304 to drive the moving rods 305 at both ends of the bidirectional threaded rod 304 to drive the fixing plate 306 to move towards each other, and fix the internal capacitor.

[0023] Refer to Figure 4 , Figure 5, the testing mechanism 5 includes a contact member 501. The outer end of the contact member 501 is connected to a square plate 502.

Rotate the bidirectional threaded rod 304 so that the moving rods 305 at both ends of the bidirectional threaded rod 304 drive the fixing plates 306 to move towards each other to fix the internal capacitor. Control the starting screw rod 204 through the moving slide table 2, so that the screw rod 204 rotates to drive the arc seat 206 at the outer end to move the substrate 207. Cooperate with the tooth blocks 208 on both sides of the lower end of the substrate 207 to slide on the outer end of the clamping strip 203, so that the fixing mechanism 3 at the upper end of the substrate 207 can move smoothly. Then, the moving slide table 2 controls the air cylinder 603 to push the pushing frame 604 downward, so that the square plate 502 moves downward and the contact member 501 contacts the pin 4. Finally, set parameters such as the test voltage and running time through the moving slide table 2, start the high-voltage power line 504 to generate a certain voltage, apply the voltage to the capacitor under test through the contact member 501. The moving slide table 2 monitors parameters such as the voltage and current of the capacitor under test in real time and displays the test data in real time. When the voltage or current of the capacitor under test exceeds the set threshold, the moving slide table 2 will automatically stop the test.
