Description

Technical Field

[0001] The invention relates to the technical field of capacitor testing, and in particular to a capacitor withstand voltage testing device. Background Art

[0002] The main purpose of the capacitor withstand voltage test is to verify whether the capacitor can maintain its electrical performance and structural integrity at rated voltage or higher voltage. This helps to ensure that the capacitor can work reliably in actual applications and avoid damage or failure due to excessive voltage. Traditionally, when conducting a withstand voltage test on a capacitor, in order to improve the test efficiency, a special device, a rack, is usually used to load multiple capacitors for testing. Through the rack, multiple capacitors can be conveniently connected in parallel and connected to a withstand voltage tester for testing. This method significantly improves the test efficiency because multiple capacitors can be tested at the same time, greatly shortening the time required for testing. However, this test method is not flawless in actual operation.

[0003] Since there are multiple capacitors on the rack, once one of the capacitors fails or is damaged, its impact will extend to the entire parallel circuit, causing the overall measurement result to deviate. This means that even if there is a problem with only one capacitor, it may cause the entire test result to fail. Therefore, when the test result is found to be abnormal, in order to accurately find the damaged capacitor, the tester needs to check each capacitor on the rack one by one. This process is not only cumbersome but also time-consuming because it requires disconnecting each capacitor one by one and then retesting until the damaged capacitor is found. This one-by-one checking method increases the workload of the test. For this reason, we propose a capacitor withstand voltage test device. Summary of the invention

When an error occurs during the overall detection of a plurality of capacitors 3, the bisection conducting component 6 is used to bisection the plurality of capacitors 3 for multiple times and sequentially connect the plurality of capacitors 3 to a withstand voltage tester 11 for testing;

[0048] Specifically, when the device is used, the staff inserts multiple capacitors 3 on the rack 2 in advance, and the rack 2 can be provided with multiple ones to improve the detection efficiency, and then docks the rack 2 with the base 1 and uses the withstand voltage tester 11 to perform synchronous testing on the multiple capacitors 3 to ensure the detection efficiency;

Specifically, when eight capacitors 3 are tested in half, only three times of half-testing are required, that is, only three tests using the withstand voltage tester 11 are required to accurately find out which capacitor 3 is damaged:

[0051] Four pairs of conductive plates 1 52 are evenly and equidistantly arranged in the base 1, each pair of conductive plates 1 52 is used in conjunction with two pairs of conductive pillars 51, and the two ends of the conductive plates 1 52 are respectively in contact with and abut against the two conductive pillars 51 and are electrically conductive therewith; two pairs of conductive plates 2 53 are evenly and equidistantly arranged in the base 1, each pair of conductive plates 2 53 is used in conjunction with two pairs of conductive plates 1 52, and the two ends of the conductive plates 2 53 are respectively electrically conductive with the two conductive plates 1 52; a pair of conductive plates 3 54 is arranged in the base 1, a pair of conductive plates 3 54 is used in conjunction with the two pairs of conductive plates 2 53, and the two ends of the conductive plates 3 54 are respectively electrically conductive with the conductive plates 2 53; a pair of conductive plates 3 54 is connected to the withstand voltage tester 11 to test multiple capacitors 3 at the same time.

[0053] A locking member 58 is provided between the conductive plate 3 54 and the conductive plate 2 53. After the conductive plate 3 54 is moved to a specific distance, the locking member 58 is used to lock the conductive plate 3 54 and the pair of conductive plates 2 53. Then, the conductive plate 3 54 is continued to be moved to drive the conductive plate 2 53 to move away from the pair of conductive plates 1 52.

[0054] A locking member 58 is also provided between the conductive plate 1 52 and the conductive plate 2 53 . After the conductive plate 2 53 is moved to a specific distance, the locking member 58 is used to lock the conductive plate 2 53 and the conductive plate 1 52 . Then, the conductive plate 2 53 is continued to be moved to drive the conductive plate 1 52 to move so that it is separated from the pair of conductive pillars 51 .

[0055] The locking member 58 includes a hollow column 59 fixedly connected to the conductive plate 2 53, a sliding column 61 is slidably connected in the hollow column 59, a spring 1 62 is arranged at one end of the sliding column 61 located in the hollow column 59, and the two ends of the spring 1 62 are respectively fixedly connected to the sliding column 61 and the hollow column 59, and two slots 63 are symmetrically provided on the conductive plate 3 54. When the sliding column 61 contacts the conductive plate 3 54, the spring 1 62 is in a compressed state. After the conductive plate 3 54 is moved to a specific distance, the spring 1 62 is reset to drive the sliding column 61 to insert into the slot 63;

[0058] Specifically, when one of the eight capacitors 3 is damaged, after the eight capacitors 3 are tested in parallel at the same time, the test data of the withstand voltage tester 11 will deviate from the normal range. At this time, the program starts to control the electric push rod 56 to drive the conductive plate three 54 to move forward a certain distance, so that the conductive plate three 54 is separated from the pair of conductive plates two 53. At this time, it is reflected on the capacitor 3, that is, only the four capacitors 3 on one side of the rack 2 are connected to the withstand voltage tester 11, and then the withstand voltage tester 11 is tested, and then two test results are generated. One data is at a normal value, which indicates that none of the four capacitors 3 is damaged. At this time, it also indicates that the bad capacitor 3 is among the four on the other side of the rack 2. Then the electric push rod 56 starts to drive the conductive plate three 54 to move in the opposite direction for an end distance. During the movement of the conductive plate three 54, the sliding column on the conductive plate two 53 After 61 is inserted into the slot 63 of the conductive plate three 54 and moves with it, the conductive plate two 53 is separated from the pair of conductive plates one 52. At this time, it is reflected in the capacitance, that is, only the two capacitors 3 on one side of the rack 2 are connected to the withstand voltage tester 11, and then the withstand voltage tester 11 is tested, and then two test results will be generated. One is that the data is not at a normal value, which indicates that one of the two capacitors 3 is damaged. Then the electric push rod 56 is started to move one end distance in the opposite direction. During this process, the sliding column 61 on the conductive plate one 52 is inserted into the slot 63 of the conductive plate two 53 and moves with it, so that the conductive plate one 52 is separated from the pair of conductive columns 51. At this time, it is reflected in the capacitor 3, that is, only one capacitor 3 is connected to the withstand voltage tester 11, and then the withstand voltage tester 11 tests it to finally find out the damaged capacitor 3.
