Description

Technical Field

[0001] This utility model relates to the field of cadmium telluride module technology, specifically to a cadmium telluride module insulation withstand voltage tester. Background Technology

[0002] Cadmium telluride (CdTe) solar modules are the main thin-film modules. Thin-film solar cells are made by attaching a very thin layer of photosensitive material onto a glass, stainless steel, or plastic substrate. The material has a high light absorption coefficient, which greatly reduces the overall thickness of the cell. A cadmium telluride (CdTe) thin-film module is a photovoltaic device formed by sequentially depositing multiple layers of semiconductor thin films on a glass substrate based on a heterojunction of p-type CdTe and n-type CdS.

[0003] Existing insulation withstand voltage testers often require manual clamping operations when performing withstand voltage tests on materials. Furthermore, insulation withstand voltage testing is a high-voltage test that poses certain risks to operators. In response to these issues, we propose a new insulation withstand voltage tester for cadmium telluride modules based on existing technology innovations. Utility Model Content

[0006] The detection device includes a precision detection test structure and a sliding device. The precision detection test structure is installed on both sides above the workbench. Multiple sliding devices are installed on the outer wall of the workbench. The precision detection test structure includes a fixed plate, a slider, and a manual locking bolt. Double probes are installed on both sides above the workbench. The upper part of the double probes is installed below a first insulating bakelite. The left side of the first insulating bakelite is installed on the right side of an adapter bracket. A first cylinder is installed above the adapter bracket. A fixed plate is installed to the left of the first cylinder. A manual locking bolt is installed on the left side below the fixed plate. A slider is installed above the fixed plate. A slide rail is installed inside the slider. Multiple reserved spaces are installed on the inner side of the slide rail. Both sides of the slide rail are connected to the inner wall of the support frame.

[0010] Preferably, the sliding device includes a second cylinder, a second insulating bakelite, and a leveling component. Multiple second detection copper electrodes are provided on the outer side of the worktable. A first detection copper electrode is installed above the second detection copper electrode. A support profile is installed on the outer side of the first detection copper electrode. A buffer pad is provided between the first detection copper electrode and the support profile.

[0015] Compared with existing technologies, the beneficial effects of this utility model are:

[0016] By setting up a precise detection test structure and sliding device, the object under test is transported below the test position by a lifting device to the test position of the insulation withstand voltage tester (the initial debugging and calibration operation method is as follows; no further adjustments are needed after each test component is calibrated). The user pushes the fixing plate to move the slider left and right on the outside of the slide rail to adjust the position of the dual probes as needed. After the position is fixed, the user manually rotates the manual locking bolt to move the top of the manual locking bolt into the reserved space on the inside of the slide rail to fix the position of the precise detection test structure, increasing the usability of the device. After fixing, the first cylinder is activated to drive the first insulating bakelite connected to the adapter bracket to slide downwards. The first insulating bakelite causes the dual probes to contact the top of the material, and through the dual probes... The needle conducts electricity to the material, then the support frame is activated, moving the second insulating bakelite connected to the horizontal adjustment component. The second insulating bakelite moves the support profile, which in turn brings the first and second copper probes into contact with the outside of the material. This allows the first and second copper probes to detect the current inside the material, enabling the device to perform a withstand voltage test. [The first and second copper probes and the dual probes are all connected to the withstand voltage tester via voltage, ensuring that the test data are displayed on the withstand voltage tester. The withstand voltage tester is electrically connected to a computer, which displays the test data for operator viewing.] This process reduces manual operation and improves operator safety.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5This utility model provides a technical solution for a cadmium telluride module insulation withstand voltage tester: A cadmium telluride module insulation withstand voltage tester includes a support frame 1, a computer 2 and a workbench 3. The computer 2 is installed on the top of the support frame 1, a fixing port is provided on the outside of the support frame 1, the workbench 3 is installed on the inside of the support frame 1, a testing device is installed on the outside of the workbench 3, and a fixing frame 6 is installed below the workbench 3.

[0028] The testing device includes a precision detection test structure 4 and a sliding device 5. The precision detection test structure 4 is installed on both sides above the workbench 3. Multiple sliding devices 5 are installed on the outer wall of the workbench 3. The precision detection test structure 4 includes a fixed plate 401, a slider 402 and a manual locking bolt 403. Double probes 406 are installed on both sides above the workbench 3. The upper part of the double probes 406 is installed below the first insulating bakelite 407. The left side of the first insulating bakelite 407 is installed on the right side of the adapter bracket 405. The upper part of the adapter bracket 405 is installed with a first cylinder 404. The left side of the first cylinder 404 is installed with a fixed plate 401. The left side below the fixed plate 401 is installed with a manual locking bolt 403. The upper part of the fixed plate 401 is installed with a slider 402. The slider 402 has a slide rail installed inside. Multiple reserved spaces are installed on the inner side of the slide rail. The reserved spaces can be adjusted according to the different components being tested. The two sides of the slide rail are connected to the inner wall of the support frame 1.

[0029] In use, the object under test is transported below the test position by a lifting device to the test position with insulation withstand voltage (the initial debugging and calibration method is as follows; after each test component is debugged, no further adjustments are needed). Based on the material's position, the user pushes the fixing plate 401, causing the slider 402 to slide left and right on the outside of the slide rail, adjusting the position of the dual probes 406 as needed. After the position is fixed, the user manually rotates the manual locking bolt 403 to move its upper part into the reserved space inside the slide rail, thus fixing the position of the precise detection and testing structure 4 and increasing the device's usability. After fixing, the first cylinder 404 is activated, causing the first insulating bakelite 407 connected to the adapter bracket 405 to slide downwards. The first insulating bakelite 407 causes the dual probes 406 to contact the upper part of the material, and the material is made conductive through the dual probes 406. The support frame 1 is then activated, which moves the second insulating bakelite 502 connected to the horizontal adjustment component 503. The second insulating bakelite 502 moves the support profile 506, which in turn moves the first and second probe copper electrodes 507 and 508 to the outside of the material. This allows the first and second probe copper electrodes 507 and 508 to detect the current inside the material, enabling the device to perform a withstand voltage test on the material. [The first probe copper electrode 507, the second probe copper electrode 508, and the dual probes 406 are all connected to the insulation withstand voltage tester via voltage connection, so that the test data from the first probe copper electrode 507, the second probe copper electrode 508, and the dual probes 406 are all displayed on the insulation withstand voltage tester. The insulation withstand voltage tester displays the test data on the computer 2 via electrical connection, allowing staff to view it.] This process reduces manual operation and improves staff safety during the material withstand voltage test.

A fine-tuning slider 509 is installed below the telescopic adjustment plate 504. A mounting plate is installed below the fine-tuning slider 509. The mounting plate is installed on the inner side of the support frame 1.

[0035] The top of the workbench 3 is on the same horizontal line as the bottom of the fixed port and the bottom of the second detection copper electrode 508.
