Description

Technical Field

[0001] This application relates to the field of transformer testing technology, specifically to a testing device. Background Technology

[0002] Currently, high-voltage transformers are a crucial component of various electrical equipment in related technologies. Because these transformers operate under high voltage and require guaranteed safety, accurate and effective testing to ensure their reliable performance is paramount. However, high-voltage transformers are generally not tested after assembly. Therefore, installing high-voltage transformers directly onto electrical equipment without factory testing can easily lead to malfunctions and cause the equipment to malfunction. Summary of the Invention

[0003] This application aims to at least solve the technical problem that high-voltage transformers, when installed and operated on electrical equipment without undergoing factory testing, are prone to malfunctions that prevent the electrical equipment from operating normally.

[0004] Therefore, this application proposes a testing device.

[0005] In view of this, this application provides a testing device for testing a sample to be tested. The sample to be tested includes a transformer and a testing fixture. The transformer is installed on the testing fixture. The testing device includes a first conveying component, a testing component, a second conveying component, and testing terminals. The first conveying component is capable of transporting the sample to be tested; the testing component is located on one side of the first conveying component; the second conveying component is located inside the testing component and is capable of receiving the sample to be tested transported by the first conveying component; the testing terminals are located inside the testing component. When testing the sample to be tested, the first conveying component can transport the sample to be tested into the testing component, and the second conveying component moves the sample to the position of the testing terminals so that the first terminal of the testing fixture contacts the testing terminals.

[0006] In this technical solution, the testing equipment is used to test the sample to be tested. The sample to be tested includes a transformer and a testing fixture. The transformer is installed on the testing fixture to facilitate testing. The testing equipment includes a first conveying assembly, a testing assembly, a second conveying assembly, and testing terminals. The first conveying assembly is capable of transporting the sample to be tested. The testing assembly is located on one side of the first conveying assembly so that the first conveying assembly can transport the sample to be tested to the testing assembly for testing. The second conveying assembly is located inside the testing assembly to facilitate its installation and fixation. The second conveying assembly can receive the sample to be tested transported by the first conveying assembly, allowing the second conveying assembly to transport the sample to be tested within the testing assembly. The testing terminals are located inside the testing assembly to facilitate their installation. When testing a sample, the first conveying component transfers the sample to the testing component, and the second conveying component moves the sample to the position of the testing terminal so that the first terminal of the testing fixture contacts the testing terminal. This allows for the detection of issues that could lead to transformer failure, reduced efficiency, or safety hazards. Therefore, by setting up the first conveying component, the testing component, the second conveying component, and the testing terminal to feed and test the transformer, automatic transformer testing can be achieved. This prevents arcing caused by short circuits when the transformer is installed on electrical equipment, thus avoiding any impact on the operation of the electrical equipment.

[0007] In addition, the testing equipment in the above-mentioned technical solution provided in this application may also have the following additional technical features: In one technical solution of this application, the first material conveying component includes a first material conveying part, a feeding bin, and a first clamping component; the first material conveying part is capable of storing the sample to be tested; the feeding bin is located on one side of the first material conveying part and has a first feeding port; the first clamping component is located inside the feeding bin, and the first clamping component is capable of clamping the sample to be tested stored on the first material conveying part through the first feeding port and transporting the sample to be tested to the second material conveying component.

[0008] In this technical solution, the first material conveying assembly includes a first material conveying component, a feeding bin, and a first clamping assembly. The first material conveying component can store the sample to be tested, so that it can provide the sample to be tested to the testing assembly when testing the transformer. The feeding bin is located on one side of the first material conveying component and has a first inlet, so that the sample to be tested can enter and exit the feeding bin through the first inlet. The first clamping assembly is located inside the feeding bin to realize the installation of the first clamping assembly. The first clamping assembly can clamp the sample to be tested stored on the first material conveying component through the first inlet and transport the sample to be tested to the second material conveying assembly, thereby improving the efficiency of the first clamping assembly feeding the sample to the second material conveying assembly.

[0009] In one technical solution of this application, the test assembly includes a test chamber with a second inlet connected to the test chamber. The test chamber can store insulating oil, and the second conveying assembly can immerse the sample to be tested in the insulating oil and bring the sample to be tested into contact with the test assembly.

[0010] In this technical solution, the testing component includes a testing chamber with a second inlet connected to it, allowing the sample to be tested to enter and exit the testing chamber through the second inlet. The testing chamber can store insulating oil, and a second conveying component can immerse the sample in the insulating oil and bring it into contact with the testing component. Since some transformers operate in insulating oil when installed on equipment, placing the sample in the insulating oil for testing simulates the actual working environment of the transformer, thereby improving the accuracy of transformer testing.

[0011] In one technical solution of this application, the test assembly further includes a test cable, one end of which passes through the test chamber and is located inside the test chamber, and the other end of which is connected to a test terminal.

[0012] In this technical solution, the testing assembly also includes a detection cable. One end of the detection cable passes through the testing chamber and is located inside the testing chamber to facilitate its installation and fixation. The other end of the detection cable is connected to a test terminal, enabling the detection cable to provide power and a detection signal to the test terminal, thereby facilitating the testing of the sample under test and ensuring the stability of transformer testing.

[0013] In one technical solution of this application, the first clamping assembly includes a clamping part, a robotic arm, and a driving part; the clamping part is capable of clamping the sample to be tested; one end of the robotic arm is connected to the clamping part and is capable of driving the clamping part to move; the driving part is disposed in the feeding bin and is connected to the other end of the robotic arm and is capable of driving the robotic arm to move.

[0014] In this technical solution, the first clamping assembly includes a clamping part, a robotic arm, and a driving part. The clamping part can clamp the sample to be tested, preventing it from falling during transport and ensuring the stability of the sample transport. One end of the robotic arm is connected to the clamping part and can drive the clamping part to move, thus enabling the robotic arm to drive the clamping part to transport the sample to be tested from the position of the first conveying component to the position of the second conveying component. The driving part is located in the feeding bin and connected to the other end of the robotic arm, enabling the driving part to drive the robotic arm to move. By including the driving part, the efficiency of sample transport can be improved.

[0015] In one technical solution of this application, the second material conveying component includes a first sliding part, a second sliding part, and a lifting part. The first sliding part is connected to the test chamber. The second sliding part is located on one side of the first sliding part and can move relative to the first sliding part. The lifting part is disposed on the second sliding part and can drive the sample to be tested to reciprocate along the direction from the bottom wall to the top wall of the test chamber.

[0016] In this technical solution, the second material conveying assembly includes a first sliding part, a second sliding part, and a lifting part. The first sliding part is connected to the test chamber; the second sliding part is located on one side of the first sliding part and can move relative to the first sliding part to achieve the installation of the first and second sliding parts. The lifting part is disposed on the second sliding part and can drive the sample to be tested to reciprocate along the bottom wall to the top wall of the test chamber to achieve the installation of the lifting part. When the clamping part transports the sample to be tested into the test chamber, the lifting part moves towards the position of the sample to be tested, so that the lifting part can receive the sample to be tested. After receiving it, the lifting part drives the sample to be tested towards the first sliding part. Since the test chamber contains insulating oil, the lifting part can drive the sample to be tested into the insulating oil. Since the second sliding part can move relative to the first sliding part, the second sliding part can drive the sample to be tested towards the position of the test terminal, so that the first terminal of the testing fixture contacts the test terminal to achieve the testing of the sample to be tested. By setting the second sliding part and the lifting part to transport the sample to be tested, the testing efficiency of the sample to be tested can be improved.

[0017] In one technical solution of this application, the feeding hopper has a first air inlet and a first air extraction port, and the first material conveying component further includes a first air inlet valve and a first vacuum valve; the first air inlet valve is disposed at the first air inlet; and the first vacuum valve is disposed at the first air extraction port.

[0018] In this technical solution, the feeding chamber has a first air inlet and a first air extraction port, and the first conveying component also includes a first air intake valve and a first vacuum valve. The first air intake valve is located at the first air inlet to facilitate its installation and fixation. The first vacuum valve is located at the first air extraction port to facilitate its installation and fixation. Since the feeding chamber needs to be in a vacuum state during the testing of the sample, a first vacuum valve is provided to facilitate vacuuming of the feeding chamber. Because the first and second inlets are closed, the inlet needs to be opened when the sample is transported into the feeding chamber. To facilitate opening the first inlet, the air pressure inside the testing chamber needs to be adjusted to the same as the outside air pressure. Therefore, by adjusting the first air intake valve to supply air to the testing chamber, the vacuum pressure inside the testing chamber can be adjusted to atmospheric pressure.

[0019] In one technical solution of this application, the test chamber has a second air inlet and a second air outlet, and the test component further includes a second air inlet valve and a second vacuum valve; the second air inlet valve is disposed at the second air inlet; the second vacuum valve is disposed at the second air outlet.

[0020] In this technical solution, the test chamber has a second air inlet and a second air outlet. The test assembly also includes a second air inlet valve and a second vacuum valve. The second air inlet valve is located at the second air inlet, and the second vacuum valve is located at the second air outlet, enabling the installation and fixation of the second air inlet valve and the second vacuum valve. Since the test chamber needs to be in a vacuum state during the testing of the sample, a second vacuum valve is provided to facilitate the vacuuming process within the test chamber. Therefore, the second air inlet valve and the second vacuum valve facilitate the vacuuming and pressure balancing processes within the test chamber.

[0021] In one technical solution of this application, the test chamber has a first oil inlet and a first oil outlet, and the test assembly further includes a first oil inlet valve and a first oil outlet valve; the first oil inlet valve is disposed at the first oil inlet and is used to deliver insulating oil into the test chamber; the first oil outlet valve is disposed at the first oil outlet.

[0022] In this technical solution, the test chamber has a first oil inlet and a first oil outlet. The test assembly also includes a first oil inlet valve and a first oil outlet valve. The first oil inlet valve is located at the first oil inlet, and the first oil outlet valve is located at the first oil outlet to facilitate their installation and fixation. During the testing of the sample, insulating oil needs to be supplied into the test chamber so that the sample can be tested in the insulating oil. Therefore, the first oil inlet and the first oil inlet valve are provided to supply insulating oil into the test chamber. By placing the first oil outlet valve at the first oil outlet, it is convenient to replace the insulating oil in the test chamber.

[0023] In one technical solution of this application, the testing equipment also includes a discharge component located on the side of the testing component away from the first material conveying component, and the discharge component is capable of transferring the tested sample.

[0024] In this technical solution, the testing equipment also includes a discharge component, located on the side of the testing component away from the first conveying component. The discharge component can transfer the tested sample. By setting the discharge component on the side of the first conveying component, the discharge component can transport the tested sample, so that the tested sample does not need to be transferred through the first conveying component again, which can greatly improve the testing efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0030] The following reference Figures 1 to 8 This application describes a detection device according to some embodiments.

[0031] like Figure 1 and Figure 2 As shown, this application provides a detection device for detecting the sample 100 to be tested, such as... Figure 3 As shown, the sample to be tested 100 includes a transformer 110 and a testing fixture 120. The transformer 110 is installed in the testing fixture 120. The testing equipment includes a first conveying component 200, a testing component 300, a second conveying component 400, and a testing terminal 500. The first conveying component 200 can transport the sample to be tested 100; the testing component 300 is located on one side of the first conveying component 200; the second conveying component 400 is located inside the testing component 300 and can receive the sample to be tested 100 transported by the first conveying component 200; the testing terminal 500 is located inside the testing component 300. When testing the sample to be tested 100, the first conveying component 200 can transport the sample to be tested 100 into the testing component 300, and the second conveying component 400 can move the sample to be tested 100 to the position of the testing terminal 500, so that the first terminal 130 of the testing fixture 120 contacts the testing terminal 500.

[0032] In this embodiment, the testing equipment is used to test the sample 100, which includes a transformer 110 and a testing fixture 120. The transformer 110 is mounted on the testing fixture 120, facilitating the testing of the transformer 110. The testing equipment includes a first conveying assembly 200, a testing assembly 300, a second conveying assembly 400, and testing terminals 500. The first conveying assembly 200 can transport the sample 100 to achieve the transport of the sample 100. The testing assembly 300 is located on one side of the first conveying assembly 200, so that the first conveying assembly 200 can transport the sample 100 to the position of the testing assembly 300 for testing. The second conveying assembly 400 is located inside the testing assembly 300, enabling the installation and fixation of the second conveying assembly 400. The second conveying assembly 400 can receive the test sample 100 transferred by the first conveying assembly 200, so that the second conveying assembly 400 can transport the test sample 100 within the test assembly 300. The test terminal 500 is located within the test assembly 300 to enable the installation of the test terminal 500. When testing the sample 100, the first conveying component 200 can transfer the sample 100 to the testing component 300, and the second conveying component 400 can move the sample 100 to the position of the testing terminal 500 so that the first terminal 130 of the testing fixture 120 comes into contact with the testing terminal 500. This allows for the detection of problems that could cause transformer 110 to malfunction, reduce efficiency, or cause safety hazards. Therefore, by setting up the first conveying component 200, the testing component 300, the second conveying component 400, and the testing terminal 500 to feed and test the transformer 110, automatic testing of the transformer 110 can be achieved. This avoids the transformer 110 from arcing due to short circuits or other reasons after installation into electrical equipment, which could affect the operation of the electrical equipment. It also prevents damage to the transformer 110 or other components during overall testing after assembly.

[0033] Furthermore, this application reduces the risk of workers being exposed to high voltage during the production process by using testing equipment to automatically test the transformer 110.

[0034] Specifically, transformer 110 is a vacuum high-voltage transformer.

[0035] Specifically, vacuum high-voltage transformers are an important component of electrical equipment. Because these vacuum high-voltage transformers operate under high voltage and require guaranteed safety, accurate and effective testing to ensure their safe and reliable performance is crucial. Vacuum high-voltage transformer testing equipment plays a key role in diagnosing abnormal conditions of transformer 110 and detecting potential problems that may lead to malfunctions, shutdowns, or safety hazards. This application employs an automated testing method for transformer 110, allowing for testing of transformer 110 before installation into electrical equipment, thereby ensuring the normal operation of transformer 110 after installation.

[0036] Specifically, after the test sample 100 is tested, the second conveying component 400 carries the test sample 100 to the side away from the test terminal 500, and the first conveying component 200 can transfer the test sample 100 on the second conveying component 400.

[0037] Specifically, such as Figure 3 As shown, the transformer 110 needs to be installed on the testing fixture 120 during the testing process to form the sample 100 to be tested. The testing fixture 120 includes two voltage divider resistors and a load RL, wherein the two voltage divider resistors include a first voltage divider resistor R1 and a second voltage divider resistor R2.

[0038] Specifically, the testing fixture 120 has an insulating base, thereby preventing electrical conduction between the testing fixture 120 and other components.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, the sample to be tested 100 includes a testing fixture 120 and a transformer 110. The transformer 110 is mounted on the testing fixture 120. One end of the high-voltage input live wire IN_L and one end of the high-voltage input neutral wire IN_N of the transformer 110 are respectively connected to the transformer 110. One end of the high-voltage output live wire OUT_L and one end of the high-voltage output neutral wire OUT_N are respectively connected to the transformer 110. The other end of the high-voltage output live wire OUT_L is connected to one end of the load RL, and the other end of the high-voltage output neutral wire OUT_N is connected to the other end of the load RL. The load RL... One end of L is connected to the first voltage divider resistor R1, and the other end of the load RL is connected to the second voltage divider resistor R2. The other end of the first voltage divider resistor R1 is connected to the live wire HV_L for outputting the high voltage signal, and the other end of the second voltage divider resistor R2 is connected to the neutral wire HV_N for outputting the high voltage signal. The high voltage input live wire IN_L, the high voltage input neutral wire IN_N, the high voltage output live wire HV_L, and the high voltage output neutral wire HV_N are all connected to the first terminal 130, thereby enabling the detection of the transformer 110 through the connection between the first terminal 130 and the test terminal 500.

[0040] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0041] like Figure 1 and Figure 2 As shown, the first material conveying assembly 200 includes a first material conveying component 202, a feeding bin 204, and a first clamping assembly 206; the first material conveying component 202 is capable of storing the sample to be tested 100; the feeding bin 204 is located on one side of the first material conveying component 202 and has a first feeding port 214; the first clamping assembly 206 is located inside the feeding bin 204, and the first clamping assembly 206 is capable of clamping the sample to be tested 100 stored on the first material conveying component 202 through the first feeding port 214 and transporting the sample to be tested 100 to the second material conveying assembly 400.

[0042] In this embodiment, the first material conveying assembly 200 includes a first material conveying component 202, a feeding bin 204, and a first clamping assembly 206. The first material conveying component 202 is capable of storing the sample 100 to be tested, so that the first material conveying component 202 can provide the sample 100 to be tested to the testing assembly 300 when testing the transformer 110. The feeding bin 204 is located on one side of the first material conveying component 202 and has a first inlet 214, so that the sample 100 to be tested can enter and exit the feeding bin 204 through the first inlet 214. The first clamping component 206 is located in the feeding bin 204 to realize the installation of the first clamping component 206. The first clamping component 206 can clamp the sample to be tested 100 stored on the first conveying component 202 through the first feeding port 214 and transport the sample to be tested 100 to the second conveying component 400, thereby enabling the first clamping component 206 to transport the sample to be tested 100, thereby improving the efficiency of the first clamping component 206 feeding the sample to the second conveying component 400.

[0043] Specifically, the first material conveying component 202 is a material conveyor belt, which can convey the sample 100 to be tested, thereby improving the testing efficiency of the transformer 110.

[0044] Specifically, a first feed valve is provided in the first feed port 214. The first feed valve can open or close the first feed port 214 to facilitate the first material conveying component 202 to transport the sample 100 to be tested.

[0045] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0046] like Figure 1 , Figure 2 and Figure 4As shown, the test assembly 300 includes a test chamber 302, which has a second inlet 304 connected to the feed chamber 204. The test chamber 302 can store insulating oil, and the second conveying assembly 400 can immerse the sample to be tested 100 in the insulating oil and bring the sample to be tested 100 into contact with the test assembly 300.

[0047] In this embodiment, the test assembly 300 includes a test chamber 302 with a second inlet 304 connected to the feed chamber 204, allowing the sample 100 to be tested within the feed chamber 204 to enter and exit the test chamber 302 through the second inlet 304. The test chamber 302 can store insulating oil, and the second conveying assembly 400 can immerse the sample 100 in the insulating oil and bring it into contact with the test assembly 300. Since some transformers 110 operate in insulating oil when installed on equipment, placing the sample 100 in the insulating oil for testing can simulate the actual working environment of the transformer 110, thereby improving the accuracy of transformer 110 testing.

[0048] Specifically, a first observation window is provided on the feed hopper 204, so as to observe the inside of the feed hopper 204 through the first observation window in order to understand the transfer process of the sample 100 to be tested.

[0049] Specifically, a second observation window is provided on the feed hopper 204, so as to observe the inside of the feed hopper 204 and understand the transfer process of the sample 100 to be tested.

[0050] Specifically, in the test chamber 302, the level of the insulating oil is lower than that of the second inlet 304, thereby preventing the insulating oil in the test chamber 302 from entering the feed chamber 204.

[0051] Specifically, a second feed valve is provided at the second feed port 304. The second feed valve can open or close the second feed port 304, thereby separating the feed chamber 204 from the test chamber 302.

[0052] Specifically, the test chamber 302 is a chamber that is resistant to high pressure, oil, and vacuum. It can use metals such as stainless steel, steel, and aluminum alloy as the outer frame. The inner wall of the test chamber 302 is equipped with insulating ceramics, which can improve the strength of the test chamber 302. Moreover, the structure of the test chamber 302 itself will not affect the testing process.

[0053] Specifically, during the testing process, the temperature inside the test chamber 302 is maintained between 50°C and 70°C to ensure that the moisture in the insulating oil can be extracted, thus avoiding excessive moisture from affecting the testing.

[0054] Specifically, since the transformer 110 operates in insulating oil when installed on electrical equipment, the requirement for a special testing environment for the transformer 110 is solved by placing the sample 100 to be tested in the insulating oil. Because the transformer 110 cannot be tested under atmospheric conditions, it is necessary to place it in insulating oil for testing, and the gas and water content in the insulating oil must be limited.

[0055] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, the test assembly 300 also includes a test cable 306, one end of which passes through the test chamber 302 and is located inside the test chamber 302, and the other end of which is connected to the test terminal 500.

[0057] In this embodiment, the test assembly 300 further includes a detection cable 306. One end of the detection cable 306 passes through the test chamber 302 and is located inside the test chamber 302 to facilitate the installation and fixation of the detection cable 306. The other end of the detection cable 306 is connected to the test terminal 500, enabling the detection cable 306 to provide power and detection signals to the test terminal 500, thereby facilitating the testing of the sample 100 under test and ensuring the stability of the testing of the transformer 110.

[0058] Specifically, the test terminal 500 includes a probe that supplies low-voltage power and measures high voltage. When the sample 100 to be tested moves to the test terminal 500, the probe contacts the first terminal 130 of the detection fixture 120 to achieve the connection between the sample 100 to be tested and the test terminal 500. The first terminal 130 and the test terminal 500 are connected by an elastic connection.

[0059] Specifically, the other end of the test cable 306 has a device for testing voltage, current, and frequency, which can simulate the operating environment of the transformer 110 after it is installed in the electrical equipment, so as to realize the testing of the transformer 110.

[0060] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0061] like Figure 1 and Figure 2As shown, the first clamping assembly 206 includes a clamping part 208, a robotic arm 210, and a driving part 212; the clamping part 208 is capable of clamping the sample 100 to be tested; one end of the robotic arm 210 is connected to the clamping part 208 and is capable of driving the clamping part 208 to move; the driving part 212 is disposed in the feed chamber 204 and is connected to the other end of the robotic arm 210 and is capable of driving the robotic arm 210 to move.

[0062] In this embodiment, the first clamping assembly 206 includes a clamping part 208, a robotic arm 210, and a driving part 212. The clamping part 208 can clamp the sample 100 to be tested. By using the clamping part 208 to clamp the sample 100 to be tested, the sample 100 to be tested can be prevented from falling during the transfer process, thereby ensuring the stability of the transfer of the sample 100 to be tested. One end of the robotic arm 210 is connected to the clamping part 208 and can drive the clamping part 208 to move, so as to realize the installation of the robotic arm 210. The robotic arm 210 can drive the clamping part 208 to transfer the sample 100 to be tested from the position of the first material conveying component 202 to the position of the second material conveying component 400. The driving part 212 is disposed in the feeding bin 204 and connected to the other end of the robotic arm 210, so as to realize the installation of the driving part 212. The driving part 212 can drive the robotic arm 210 to move. By setting the driving part 212, the efficiency of the transfer of the sample 100 to be tested can be improved.

[0063] Specifically, the clamping part 208 is a loading robot, which can be a chuck or a clamping robot, thereby achieving the clamping of the sample 100 to be tested.

[0064] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0065] like Figure 1 and Figure 2 As shown, the second material conveying component 400 includes a first sliding part 410, a second sliding part 420, and a lifting part 430. The first sliding part 410 is connected to the test chamber 302. The second sliding part 420 is located on one side of the first sliding part 410 and can move relative to the first sliding part 410. The lifting part 430 is disposed on the second sliding part 420 and can drive the sample to be tested 100 to reciprocate along the direction from the bottom wall to the top wall of the test chamber 302.

[0066] In this embodiment, the second conveying assembly 400 includes a first sliding part 410, a second sliding part 420, and a lifting part 430. The first sliding part 410 is connected to the test chamber 302; the second sliding part 420 is located on one side of the first sliding part 410 and can move relative to the first sliding part 410 to realize the installation of the first sliding part 410 and the second sliding part 420. The lifting part 430 is disposed on the second sliding part 420 and can drive the sample to be tested 100 to reciprocate along the direction from the bottom wall to the top wall of the test chamber 302 to realize the installation of the lifting part 430. When the clamping part 208 transports the sample to be tested 100 into the test chamber 302, the lifting part 430 moves toward the position of the sample to be tested 100, thereby making the lifting part 430 move. The lifting part 430 can receive the sample 100 to be tested. After receiving it, the lifting part 430 moves the sample 100 towards the first sliding part 410. Since the test chamber 302 contains insulating oil, the lifting part 430 can move the sample 100 into the insulating oil. Since the second sliding part 420 can move relative to the first sliding part 410, the second sliding part 420 can move the sample 100 towards the test terminal 500, thereby making the first terminal 130 of the detection fixture 120 contact the test terminal 500 to realize the detection of the sample 100. By setting the second sliding part 420 and the lifting part 430 to transport the sample 100 to be tested, the detection efficiency of the sample 100 can be improved.

[0067] Specifically, the lifting unit 430 is a mechanical chuck, which can hold the sample 100 to be tested and can reciprocate along the bottom wall to the top wall of the test chamber 302.

[0068] Specifically, the second sliding part 420 is a movable guide rail that can move along the length of the first sliding part 410, thereby moving the sample 100 to be tested within the test chamber 302.

[0069] Specifically, the test terminal 500 is a spring terminal, and the second material conveying assembly 400 also includes a first drive motor and a second drive motor. The first drive motor can drive the lifting part 430 to move, and the second drive motor can drive the second sliding part 420 to move. The contact strength between the first terminal 130 and the test terminal 500 is ensured by the second drive motor and the spring tension. The precision at the millimeter level is sufficient between the second sliding part 420 and the first sliding part 410.

[0070] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0071] like Figure 1 and Figure 2As shown, the feeding hopper 204 has a first air inlet 216 and a first air extraction port 218. The first material conveying component 200 also includes a first air inlet valve 220 and a first vacuum valve 222. The first air inlet valve 220 is disposed at the first air inlet 216. The first vacuum valve 222 is disposed at the first air extraction port 218.

[0072] In this embodiment, the feeding hopper 204 has a first air inlet 216 and a first air extraction port 218. The first conveying assembly 200 further includes a first air inlet valve 220 and a first vacuum valve 222. The first air inlet valve 220 is disposed at the first air inlet 216 to enable its installation and fixation, allowing it to open or close the first air inlet 216. The first vacuum valve 222 is disposed at the first air extraction port 218 to enable its installation and fixation, allowing it to open or close the first air extraction port 218. Since the feeding hopper 204 needs to be in a vacuum state during the testing of the sample 100, the first vacuum valve 222 is provided to facilitate vacuuming of the feeding hopper 204. Since the first inlet 214 and the second inlet 304 are closed, the first inlet 214 needs to be opened when the sample 100 to be tested is transported into the feed chamber 204. In order to facilitate opening the first inlet 214, the air pressure in the test chamber 302 needs to be adjusted to the same as the outside air pressure. Therefore, by adjusting the first air inlet valve 220 to supply air into the test chamber 302, the vacuum air pressure in the test chamber 302 can be adjusted to atmospheric pressure.

[0073] Specifically, the first inlet valve 220 can introduce dried nitrogen gas, and the first vacuum valve 222 is connected to a vacuum pump, which can perform vacuuming on the feed chamber 204.

[0074] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0075] like Figure 1 and Figure 2 As shown, the test chamber 302 has a second air inlet 308 and a second air extraction port 310. The test assembly 300 also includes a second air inlet valve 312 and a second vacuum valve 314. The second air inlet valve 312 is disposed at the second air inlet 308. The second vacuum valve 314 is disposed at the second air extraction port 310.

[0076] In this embodiment, the test chamber 302 has a second air inlet 308 and a second air extraction port 310. The test assembly 300 also includes a second air inlet valve 312 and a second vacuum valve 314. The second air inlet valve 312 is disposed at the second air inlet 308 so that the second air inlet valve 312 can open or close the second air inlet 308. The second vacuum valve 314 is disposed at the second air extraction port 310 so that the second vacuum valve 314 can open or close the second air extraction port 310, thereby realizing the installation and fixation of the second air inlet valve 312 and the second vacuum valve 314. Since the test chamber 302 needs to be in a vacuum state during the testing of the sample 100, the second vacuum valve 314 is provided to facilitate the vacuuming process inside the test chamber 302. Therefore, the second air inlet valve 312 and the second vacuum valve 314 are provided to facilitate the vacuuming and pressure balancing processes of the test chamber 302.

[0077] Specifically, the second inlet valve 312 can introduce dried nitrogen gas, and the second vacuum valve 314 is connected to a vacuum pump, which can evacuate the test chamber 302.

[0078] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0079] like Figure 1 and Figure 2 As shown, the test chamber 302 has a first oil inlet 316 and a first oil outlet 318. The test assembly 300 also includes a first oil inlet valve 320 and a first oil outlet valve 322. The first oil inlet valve 320 is disposed at the first oil inlet 316 and is used to deliver insulating oil into the test chamber 302. The first oil outlet valve 322 is disposed at the first oil outlet 318.

[0080] In this embodiment, the test chamber 302 has a first oil inlet 316 and a first oil outlet 318. The test assembly 300 also includes a first oil inlet valve 320 and a first oil outlet valve 322. The first oil inlet valve 320 is disposed at the first oil inlet 316, and the first oil outlet valve 322 is disposed at the first oil outlet 318, so as to realize the installation and fixation of the first oil inlet valve 320 and the first oil outlet valve 322. This allows the first oil inlet valve 320 to open or close the first oil inlet 316, and the first oil outlet valve 322 to open or close the first oil outlet 318. During the testing of the sample 100, insulating oil needs to be supplied into the test chamber 302 so that the sample 100 can be tested in the insulating oil. Therefore, the first oil inlet 316 and the first oil inlet valve 320 are provided to supply insulating oil into the test chamber 302. By disposing of the first oil outlet valve 322 at the first oil outlet 318, it is convenient to replace the insulating oil in the test chamber 302.

[0081] Specifically, the first oil inlet valve 320 is located away from the second air inlet valve 312.

[0082] Specifically, the first oil inlet valve 320 can be connected to an external oil filter, through which insulating oil capable of withstanding high voltage can be injected into the test chamber 302.

[0083] Specifically, when the withstand voltage rating of the insulating oil in the test chamber 302 is insufficient, the first drain valve 322 can drain the insulating oil in the test chamber 302 back to the oil filter for re-filtration, thereby ensuring the accuracy of the test.

[0084] Specifically, the test chamber 302 also has a second oil drain port, and the test assembly 300 also includes a second oil drain valve. The second oil drain valve is located at the second oil drain port. After the test sample 100 is tested, it needs to be transferred from the second material conveying assembly 400 to the first material conveying component 202 via the first material conveying assembly 200. Since the test sample 100 is immersed in insulating oil during the test, some insulating oil will drip into the feed chamber 204 during the transfer process. The residual insulating oil in the feed chamber 204 can be discharged by setting the second oil drain valve.

[0085] Specifically, a float device is also installed in the test chamber 302 to prevent the insulating oil level from being too high and flowing into the feed chamber 204.

[0086] Specifically, a heater is also provided in the test chamber 302. The heater can heat the test chamber 302, thereby increasing the temperature of the insulating oil. The heater in the test chamber 302 ensures that the oil temperature is 50°C to 70°C, which can ensure the accuracy of the test of the sample 100.

[0087] Specifically, the insulating oil in the test chamber 302 can be heated by a heater to a temperature of 60°C.

[0088] This embodiment provides a detection device, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0089] like Figure 1 , Figure 2 and Figure 5 As shown, the testing equipment also includes a discharge component 600, located on the side of the testing component 300 away from the first material conveying component 200. The discharge component 600 can transfer the tested sample 100 after testing.

[0090] In this embodiment, the testing device also includes a discharge component 600, located on the side of the testing component 300 away from the first conveying component 200. The discharge component 600 can transfer the tested sample 100 after testing. By setting the discharge component 600 on one side of the first conveying component 200, the discharge component 600 can transport the tested sample 100 after testing, so that the tested sample 100 does not need to be transferred through the first conveying component 200 again, thereby greatly improving the testing efficiency.

[0091] Specifically, the discharge assembly 600 includes a discharge bin 610 and a second conveying component 620, the second conveying component 620 being a discharge conveyor belt.

[0092] Specifically, such as Figure 6 , Figure 7 and Figure 8 As shown, the testing equipment of this application tests the transformer 110 in the following manner: 1. Material Retrieval Process: A first feed valve is provided at the first feed inlet 214. The first feed valve can open or close the first feed inlet 214. First, the first feed valve is opened, and the clamping part 208 clamps the sample to be tested 100. The clamping part 208 drives the sample to be tested 100 back into the feed chamber 204. The first feed valve is closed, the first air inlet valve 220 is closed, and the first vacuum valve 222 is opened. At this time, the second air inlet valve 312 of the test chamber 302 is closed. The insulating oil level in the test chamber 302 is injected to the required position. The first oil inlet valve 320 and the first oil outlet valve 322 are closed. The test chamber 302 has been evacuated by the second vacuum valve 314 and is waiting for the feed chamber 204 to be evacuated.

[0093] 2. Feeding Process: Inside the test chamber 302, the second sliding part 420 drives the lifting part 430 to move along the first sliding part 410 to the receiving position, and the lifting part 430 moves to the position of the second feed port 304. The level of insulating oil in the test chamber 302 is checked to see if it exceeds the standard. If it does not exceed the standard, no alarm is triggered, and the next step is executed. If it exceeds the standard, an alarm is triggered, the second air inlet valve 312 is opened to introduce dry nitrogen, the first oil drain valve 322 is opened to drain the oil, and the second air inlet valve 312 is closed after the insulating oil level is lower than required. The second vacuum valve 314 is opened to evacuate the test chamber 302. After the vacuum reaches the standard, the next step is executed. The second feed valve is opened, and the clamping part 208 feeds the sample 100 to be tested into the test chamber 302. The lifting part 430 clamps the sample 100 and rises slightly; the clamping part 208 returns to the feed chamber 204, and the second feed valve is closed.

[0094] 3. Testing Process: The lifting unit 430 resets, immersing the sample 100 to be tested in the insulating oil. The second sliding unit 420 moves the sample 100 to the position of the test terminal 500. The first terminal 130 of the testing fixture 120 makes tight contact with the test terminal 500, thus starting the test. If the transformer 110 sparks in the insulating oil, open the second air inlet valve 312 of the test chamber 302 and open the first oil drain valve 322. Wait for the insulating oil in the test chamber 302 to be drained. Close the second air inlet valve 312 and the first oil drain valve 322, open the second vacuum valve 314, wait for the vacuum to reach the standard, open the first oil inlet valve 320, and close the first oil inlet valve 320 after the oil filling reaches the standard. Retest the transformer 110. If it sparks again, it indicates that the transformer 110 is faulty and needs to be unloaded and transported out. If the transformer 110 no longer sparks after the insulating oil is replaced and all testing steps can be performed, it indicates that the transformer 110 is fault-free.

[0095] 4. Return Process: After the test is completed, regardless of whether the test is qualified or unqualified, the sample 100 will enter the return process. If the transformer 110 sparks again after the insulating oil is replaced, it is judged as unqualified. Then, the normal return procedure is executed first. After closing the second air inlet valve 312 of the test chamber 302, the above-mentioned oil draining and refilling process is executed. Normal return process: The second sliding part 420 moves the lifting part 430 to the position to receive the sample 100. The lifting unit 430 rises to the position of the second feed port 304, opens the second feed valve, and the clamping unit 208 extends into the test chamber 302. The lifting unit 430 releases the sample 100 to be tested, which falls onto the clamping unit 208. The clamping unit 208 retracts to the feed chamber 204, and the second feed valve is closed. The first air inlet valve 220 is opened. After the air pressure in the feed chamber 204 stabilizes, the second oil drain valve is opened. The first air inlet valve 220 and the second oil drain valve of the feed chamber 204 are closed, and the first feed valve is opened. The clamping unit 208 transports the tested sample 100 to the clamping unit 208. The clamping unit 208 descends to a certain height so that the transformer 110 falls onto the clamp of the feeding conveyor belt. The clamping unit 208 is then pulled back to the feed chamber 204 and reset. This completes the testing of the transformer 110, thus achieving fully automated testing of the transformer 110, reducing manual labor and improving testing efficiency.

[0096] Specifically, in related technologies, vacuum high-voltage transformers require immersion in filtered insulating oil in a vacuum environment for testing. Therefore, they cannot be tested under normal conditions after assembly. Testing can only be performed after installation in actual equipment, such as an X-ray tube. Any problem with the transformer will cause arcing in the assembled equipment, requiring disassembly and reassembly, wasting time and potentially resulting in the scrapping of other high-value materials. Vacuum high-voltage transformer testing equipment plays a crucial role in the stable performance of vacuum high-voltage transformers. Therefore, this equipment can detect problems that may lead to transformer failure, reduced efficiency, or safety hazards. Due to the critical nature of vacuum high-voltage transformers, any fault can significantly impact electrical equipment, leading to prolonged downtime or costly repairs. Timely testing ensures the safe and reliable operation of these transformers, avoids substantial repair costs, and minimizes the risk of system interruptions or short circuits.

[0097] The testing equipment of this application is used to test the performance of transformer 110. By connecting the first terminal 130 of the testing fixture 120 to the test terminal 500, and connecting one end of the testing cable 306 to the test terminal 500, while the other end of the testing cable 306 is connected to a high-voltage capacitor, a high-voltage switch, measuring instruments, and a control system, these components can be combined to form test circuits with different configurations to meet the testing requirements of different types of transformer 110. The high-voltage applied to the transformer 110 port is controlled to be stable at the required level. This can be adjusted according to testing requirements, thereby precisely controlling the high-voltage and ensuring test accuracy. A vacuum pump evacuates the gas from the testing equipment, ensuring a vacuum environment for testing transformer 110 and providing a suitable environment for testing. The lifting unit 430 is used to lift and lower the sample 100 to be tested, allowing for flexible testing of different types of transformer 110.

[0098] The principle of the vacuum high-voltage transformer testing equipment in this application is as follows: The vacuum high-voltage transformer testing equipment mainly uses an artificially created high-voltage, low-pressure environment to test the electrical performance of the vacuum high-voltage transformer under different voltage and vacuum conditions. The vacuum environment can reduce the gas pressure inside the transformer 110 to an extremely low level, thereby eliminating the influence of gas discharge and accelerating moisture evaporation. By generating a high-voltage electric field, one side of the transformer 110 is connected to the high-voltage terminal, and the other side is connected to the ground terminal. Measuring instruments are used to monitor and test the transformer 110. The testing requirements include insulation resistance under different voltages, surface discharge, and distance discharge performance. Simultaneously, in a vacuum environment, the partial discharge and thermal stability characteristics within the transformer 110 also need to be tested, thus achieving the testing of the transformer 110. The testing equipment of this application is mainly used in the manufacturing, installation, and maintenance of the transformer 110 to ensure the stability and reliability of its performance. In addition, the testing equipment can also be applied in the research field, saving the cost and time associated with transformer 110 insulation testing. Its use can effectively improve the production and operating efficiency of the transformer 110 and ensure the long-term stable operation of electrical equipment.
