[0035] As Figure 1 and 2 As shown in the embodiment of the present application, the copper bar insulation withstand voltage detection device; including insulation withstand voltage tester 600, rack 100, lower mold 200, upper mold 300 and height driving mechanism 400;The lower mold 200 includes a second support seat 210 and a second conductor 220;The second support seat 210 is connected to the inner bottom of the rack 100;The second conductor 220 is connected to the side surface of the second support seat 210 away from the rack 100;The upper mold 300 includes a first support seat 310 and a first conductor 320;The first conductor 320 is connected to one side surface of the first support seat 310, and is arranged above the second conductor 220;The side surface of the first support seat 310 away from the first conductor 320 is connected to the movable end of the height driving mechanism 400;The mounting end of the height driving mechanism 400 is connected to the rack 100;The first conductor 320 and the second conductor 220 are provided with a test placing cavity 500;The test placing cavity 500 is used for placing copper bar;The first conductor 320 and the second conductor 220 are electrically connected with the insulation withstand voltage tester 600 respectively. Wherein, the insulation withstand voltage tester 600 is arranged at the outer side end of the rack 100.

[0036] The technical scheme of the present application is characterized in that the highly-driven mechanism is used to push and extrude the conductive copper bar into the test cavity between the first and second conductive bodies, thereby increasing the contact area with the conductive copper bar, improving the test coverage and efficiency, and ensuring the test safety; and the risk of product adhesion after testing or partial position leakage scanning and insufficient testing is avoided.

[0037] The insulation withstand voltage tester 600 applies a voltage of 2 times the rated voltage or more to the copper bar, a higher and more concentrated field strength is established at the longitudinal insulation defect, and the voltage of the copper bar reaches and exceeds the breakdown voltage at the dielectric defect. The induced voltage withstand test applies a frequency of 2 times the rated frequency or more to the copper bar, and the higher frequency can greatly reduce the breakdown voltage of the solid dielectric, making the insulation defect more likely to be broken down; the action time of the applied voltage specified by the induced voltage withstand test can also ensure the breakdown of the insulation defect; therefore, the induced voltage withstand test can reliably detect the insulation performance of the copper bar. Further, the insulation withstand voltage tester 600 selects TH9320, and the test range is 5KV.

Further, the number of the second support seats 210 is two; so as to test the voltage resistance between the positive and negative copper bars, the voltage resistance between the positive copper bar and the insulation layer, and the voltage resistance between the negative copper bar and the insulation layer; thereby improving the test efficiency.

[0039] Specifically, in some embodiments, as shown in Figure 1 and 2 the copper bar insulation withstand voltage detection device further comprises a control component 700; the control component 700 is arranged on the outer side of the rack 100; the insulation withstand voltage tester 600, the height driving mechanism 400, the first conductive body 320, and the second conductive body 220 are electrically connected to the control component 700. In some embodiments, the insulation withstand voltage tester 600 and the height driving mechanism 400 are respectively electrically connected to the control component 700; two different connection ends of the control component 700 are respectively electrically connected to the first conductive body 320 and the second conductive body 220; so as to realize the insulation withstand voltage test of different groups of copper bars by a single insulation withstand voltage tester 600, thereby reducing the cost and improving the test efficiency. Further, as shown in Figure 1As shown, the eighth lead port 601 (positive electrode) and the ninth lead port 602 (negative electrode) of the insulation voltage tester 600 are respectively electrically connected with the first lead port 701 and the second lead port 702 of the control component 700; the height driving mechanism 400 is electrically connected with the third lead port 703 of the control component 700; one of the second conductive bodies 220 and one of the first conductive bodies 320 are respectively electrically connected with the fourth lead port 704 and the fifth lead port 705 of the control component 700; the other of the second conductive bodies 220 and the other of the first conductive bodies 320 are respectively electrically connected with the sixth lead port 706 and the seventh lead port 707 of the control component 700.

[0040] Specifically, in some embodiments, the first conductive body 320 is selected from a first conductive foam; and the second conductive body 220 is selected from a second conductive foam. Wherein, the conductive foam is a conductive cloth wrapped on a fire-retardant sponge, which has good surface conductivity after a series of treatments. The conductive foam can be: aluminum foil cloth foam, conductive fiber cloth foam, gold-plated cloth foam, carbon-plated cloth foam, etc. The structure can effectively protect the copper bar and ensure the accuracy of the test through the conductive performance and buffering performance of the first conductive foam and the second conductive foam.

[0041] Specifically, in some embodiments, as shown in Figure 1 and 2 The rack 100 includes a first mounting plate 101, a second mounting plate 103 and at least three support columns 102; the first mounting plate 101 is arranged side by side with the second mounting plate 103; the two side ends of each support column 102 are respectively connected to the first mounting plate 101 and the second mounting plate 103; the second support seat 210 is connected to the first mounting plate 101; the height driving mechanism 400 is connected to the second mounting plate 103; and the lower mold 200 is arranged between the first mounting plate 101 and the second mounting plate 103.

[0042] Specifically, in some embodiments, as shown in Figure 1 and 2 The height driving mechanism 400 includes a lifting driving cylinder 401, a connecting support 402 and a mounting seat 404; the lifting driving cylinder 401 is connected to the inner top of the rack 100 (the second mounting plate 103), and passes through the rack 100 and is connected with the connecting support 402; the connecting support 402 is connected with the mounting seat 404 (detachable); the first support seat 310 is connected to the bottom of the mounting seat 404; and the connecting support 402 is slidingly connected to the rack 100 (the support column 102 inside). Figure 2As shown, the height driving mechanism 400 further comprises a sliding limiting block 403; an inner wall of the sliding limiting block 403 is slidably connected to the support column 102 (in the rack 100); and an outer wall of the sliding limiting block 403 is connected to the mounting seat 404. That is, the lowering operation of the lifting driving cylinder 401 is driven to tightly wrap the copper bar with the first and second conductive bodies 320 and 220, so as to realize the complete contact between the copper bar and the first and second conductive bodies 320 and 220, effectively protect the copper bar, and ensure the accuracy of the test.

[0043] Specifically, in some embodiments, as shown in Figure 2 and 3 As shown, the second support seat 210 is provided with a second abutting rod 240 on one side surface thereof facing the first support seat 310; the first support seat 310 is provided with a first abutting rod 330 on one side surface thereof facing the second support seat 210; and the projection of the second abutting rod 240 towards the first abutting rod 330 at least partially overlaps the first abutting rod 330. That is, the mutual abutting limiting action of the first and second abutting rods 330 and 240 can avoid the excessive compression of the copper bar caused by the excessive lowering of the first conductive body 320, thereby improving the protection performance of the copper bar and ensuring the safe test.

[0044] Specifically, in some embodiments, as shown in Figure 1 and 3 As shown in Figs. 1, 2, 3 and 4, the bottom of the first support seat 310 is provided with a first mounting groove 311; the first conductive body 330 is detachably connected (by clamping or through bolts) to the inner wall of the first mounting groove 311; and the projection of the first conductive body 330 towards the copper bar fully covers the copper bar.

The metal elastic protrusion 221 is a metal spring post. Through the elastic compression of the metal elastic protrusion 221, it ensures maximum contact between the copper busbar and the first conductor 330 during downward compression, thereby improving the full-range coverage test performance. Furthermore, due to the flexibility of the second conductor 220, it collapses and deforms towards the interior of the first conductor 330 during the elastic compression of the metal elastic protrusion 221, further improving the maximum contact between the second conductor 220 and the bottom of the copper busbar, thus enhancing the full-range coverage test performance.

[0046] Specifically, in some implementations, such as Figure 4 and 5 As shown, the second support base 210 includes a bottom support portion 211 and at least one inner partition portion 212; the bottom of the bottom support portion 211 is connected to the frame 100 (the first mounting plate 101); the inner partition portion 212 is connected to the upper surface of the bottom support portion 211, and one end of the second conductor 220 abuts against the inner partition portion 212; and at least one placement groove 213 is provided between the inner partition portion 212, the second conductor 220 and the bottom support portion 211; each placement groove 213 is used to place the bent portion of the copper busbar. This structure, through the partitioned design of the second support base 210, can ensure the comprehensiveness of testing at different positions of the copper busbar, thereby improving testing efficiency. For example, Figure 5 As shown, the first conductor 320 has a positioning post on one side of its surface facing the placement groove 213; the placement groove 213 has a positioning hole 214 corresponding to the positioning post; the positioning post passes through the copper busbar and is connected to the inner wall of the positioning hole 214. This structure achieves the positioning and clamping function of the copper busbar, thereby improving the stability of the test. Further, as... Figure 5 As shown, the bottom support portion 211 is provided with at least one first side partition 215 and at least one second side partition 216; the first conductor 320 is disposed between the mounting side surface 217 and the second side partition 216 to improve the limiting and clamping effect of the first conductor 320, thereby improving the stability of the test. Furthermore, as... Figure 5 As shown, the bottom support 211 is provided with an assembly side surface 217; the assembly side surface 217 is provided with a side partition plate 230; the side partition plate 230 and the inner partition 212 form the placement groove 213; to improve the limiting effect of this part of the copper busbar, thereby improving the stability of the test.

As shown in FIG. 5, the transfer pushing mechanism 800 further comprises at least two first limiting plates 811 and at least one second limiting plate 812; all the first limiting plates 811 are arranged side by side at the two side ends of the guide rod 815; and the first limiting plates 811 abut against the transfer driving motor 810; the second limiting plate 812 is connected to the rack 100 (in the first mounting plate 101) and abuts against the support plate 820; and the transfer sliding block 830 is arranged between the first limiting plate 811 and the second limiting plate 812. That is, the first limiting plate 811 realizes the separation protection of the transfer driving motor 810, avoiding damage caused by the sliding impact of the transfer sliding block 830; and the limiting abutment of the second limiting plate 812 avoids damage caused by the sliding falling of the transfer sliding block 830; thereby realizing the stable feeding and discharging of the copper bars to be tested and improving the operation efficiency. Figure 4 Figure 4 As shown in FIG. 5, the transfer pushing mechanism 800 further comprises a guide sliding rail 813 and a transfer sliding block 814; the guide sliding rail 813 is fixedly connected to the rack 100 (in the first mounting plate 101); the bottom of the transfer sliding block 814 is in sliding connection with the guide sliding rail 813; and the top of the transfer sliding block 814 is connected to the support plate 820.
