Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a withstand voltage testing device for insulating components. Background Technology

[0002] Withstand voltage testing of insulation components is an important testing method to ensure the reliable insulation performance of insulation components under certain pressure conditions and to protect the safety of electrical workers. It tests the insulation performance of insulation components under specified pressure to determine whether they can effectively isolate current, prevent electric shock accidents during electrical work, and ensure that insulation components can be used safely and reliably.

[0003] A search of Chinese Patent Publication No. CN221650071U reveals a withstand voltage testing device for insulating components used in the manufacture of new energy charging piles. This patent includes a base, a test platform fixedly connected to the top of the base, a top frame fixedly connected to the top of the base, sliders symmetrically fitted on the side walls of the top frame, a long plate fixedly connected to the side walls of two sliders, a pressure detection block fixedly connected to the bottom of the long plate, multiple long grooves on the bottom of the pressure detection block, a sliding plate slidably connected to the inner wall of each long groove, a support column fixedly connected to the bottom of each sliding plate, and a detection plate fixedly connected to the bottom of each support column. This device senses the pressure generated by the compression of a spring through a pressure detector and provides timely feedback of the detection data. Furthermore, the use of multiple detection plates allows for simultaneous testing of multiple insulating components, accelerating the testing speed. However, current devices for simultaneous testing of multiple insulating components often have specific requirements regarding the shape and placement of the insulating components; otherwise, uneven pressure may occur, resulting in some insulating components not receiving effective pressure testing while others experience excessive pressure, affecting the reliability of the withstand voltage test data and requiring manual adjustment, thus impacting testing efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, an insulation withstand voltage testing device includes a base plate 101, a bracket 102 bolted to the top of the base plate 101, a test platform 103 bolted to the top of the base plate 101, a fixing mechanism on the test platform 103, and a power mechanism mounted on the bracket 102. The power mechanism includes a hydraulic cylinder 301, the output end of which is bolted to a mounting frame 302. A fixing plate 304 is bolted to the mounting frame 302, and a guide shaft 305 is bolted to the fixing plate 304. A transmission mechanism is movably mounted within the mounting frame 302, and the transmission mechanism includes a first balancing component. The first balancing component includes two opposing first connecting blocks 401, which are slidably connected to the guide shaft 305. A first gear 402 is rotatably connected to the middle position inside the mounting frame 302. The two opposing sides of the first connecting blocks 401 are bolted together. The first rack 403 meshes with the first gear 402. A second balancing component is provided at the bottom of the first connecting block 401. A testing mechanism is provided on the second balancing component. The testing mechanism includes a mounting shell 501. Two pressing blocks 503 are movably arranged inside the mounting shell 501. A pressure test head 507 is bolted to the bottom of the pressing block 503. A pressure sensor is integrated on the pressure test head 507. The pressure sensor is electrically connected to an external controller. When performing a withstand voltage test, the pressure test head 507 presses against the top of the insulating component and applies pressure to it. It can test the withstand voltage performance of multiple insulating components at the same time. A third balancing component is provided inside the pressing block 503. The third balancing component is used to adapt the pressure test head 507 to insulating components of different shapes. It allows the two pressure test heads 507 in the same mounting shell 501 to move independently to adapt to local height changes or irregular shapes of the top of the insulating component.

[0027] In this embodiment, the third balancing component includes a third gear 505, which is rotatably connected to the mounting housing 501. A third rack 504, which meshes with the third gear 505, is bolted to the opposite side of the lower pressure block 503. A guide post 506 is slidably connected to the lower pressure block 503 and bolted to the mounting housing 501. The arrangement of the third rack 504 and the third gear 505 allows the other lower pressure block 503 to continue moving downward relative to the mounting housing 501 when one of the lower pressure blocks 503 is pressed against the insulating element, thereby improving the adaptability to insulating elements of different shapes.

[0028] In this embodiment, several sets of vertically arranged guide bars 306 are bolted to the inner side of the mounting frame 302, and several guide grooves 502 are opened on the outer side of the mounting shell 501. The guide bars 306 are slidably connected in the guide grooves 502. The guide shaft 305, guide bars 306 and guide rod 303 are arranged in parallel, ensuring that the movement direction of the first connecting block 401 and the mounting shell 501 is in the vertical direction, thereby improving the accuracy of the pressure resistance test.

[0029] In this embodiment, the second balancing assembly includes two sets of pressure rods 404. The pressure rods 404 are bolted to the bottom of the first connecting block 401. A second gear 405 is rotatably connected to the inner side of each set of pressure rods 404. A second connecting block 406 is bolted to the mounting housing 501. A second rack 407 is bolted to the opposite side of the second connecting block 406. The second rack 407 meshes with the second gear 405.

[0030] In this embodiment, a number of guide rods 303 are bolted to the top of the mounting frame 302. The guide rods 303 are slidably connected to the bracket 102. The guide rods 303 can guide the movement of the mounting frame 302.

[0031] In this embodiment, the fixing mechanism includes several mounting blocks 201. A cylinder 202 is bolted to the mounting block 201. A push head 203 is inserted into the output end of the cylinder 202. A fixing block 204 is bonded to the side of the mounting block 201 opposite to the push head 203. A voltage tester 205 is bolted into the mounting block 201. The push head 203 and the fixing block 204 are made of rubber composite material with added conductive material and are connected to the voltage tester 205 through an electrical connection wire. Before the withstand voltage test, the cylinder 202 moves the push head 203 toward the fixing block 204, which can clamp the side of the insulating component and fix the position of the insulating component during the withstand voltage test.

[0032] Working principle: When using this device, the operator places the insulating component to be tested between the mounting blocks 201 and simultaneously starts the cylinders 202. The cylinders 202 push the push head 203 towards the fixed block 204, and the insulating component is clamped between the push head 203 and the fixed block 204, so that the positive and negative poles on each push head 203 and fixed block 204 are in contact with the insulating component. When the withstand voltage test begins, the hydraulic cylinder 301 is started. The output shaft of the hydraulic cylinder 301 pushes the mounting frame 302 downward. The mounting frame 302 drives the first connecting block 401 downward through the first gear 402 and the first rack 403. The first connecting block 401 drives the second gear 405 downward through the pressure rod 404. The second gear 405 drives the second connecting block 406 downward through the second rack 407. The mounting shells 501 on each of the second connecting blocks 406 move synchronously until the pressure test head 507 on one mounting shell 501 is first moved. Upon contact with the insulating component, the mounting housing 501 at that position stops moving. Another mounting housing 501 in the same group continues to move, causing the second gear 405 corresponding to that group of mounting housings 501 to rotate, resulting in misalignment of the two second connecting blocks 406. Simultaneously, the two first connecting blocks 401 also misalign due to the engagement of the first gear 402 and the first rack 403, until all pressure test heads 507 are in contact with the top of their respective insulating components. The output shaft of the hydraulic cylinder 301 continues to extend, allowing the pressure test heads 507 to apply force evenly to the insulating components for withstand voltage testing. The pressure sensors on the pressure test heads 507 transmit data from each group to an external controller, enabling accurate withstand voltage testing of multiple insulating components. During the test, the voltage tester 205 is activated, and the voltage reading should always be zero. After the test is completed, the output end of the hydraulic cylinder 301 retracts, completing the withstand voltage test of the insulating components.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
