[0002] In the operation of power systems, the safe and stable operation of high-voltage electrical components is particularly critical and important, as it directly relates to the reliability and safety of the entire power system. To ensure that these high-voltage electrical components can operate normally in various complex environments, withstand voltage testing, as an indispensable technical means, is widely used to evaluate and test the insulation performance of high-voltage electrical components. Through withstand voltage testing, potential insulation defects can be effectively detected and prevented, thereby ensuring the safety and stability of high-voltage electrical components in actual operation and ensuring the overall operational safety of the power system.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-5 As shown, this utility model provides a technical solution: a high-voltage electrical component withstand voltage testing device, including an operating table 1. The top of the operating table 1 is provided with a protective cover 2 for covering the high-voltage electrical component. An air heater 201 for heating the air inside the protective cover 2 is fixedly installed on the top of the protective cover 2. A blower mechanism 3 for blowing the heat from the air heater 201 into the protective cover 2 is provided above the protective cover 2 near the air heater 201. An inlet 202 for facilitating the entry of leads into the protective cover 2 is provided on one side wall of the protective cover 2. A lead protection mechanism 4 for protecting the lead connection of the high-voltage electrical component is provided on the inner wall of the protective cover 2 near the inlet 202. A withstand voltage tester 5 for testing the withstand voltage of the high-voltage electrical component is placed on one side of the top of the operating table 1. The withstand voltage tester 5 is electrically connected to the high-voltage electrical component through leads.

[0022] During withstand voltage testing, the high-voltage electrical components are first placed on the 103 placement platform on the operating table 1, ensuring that their leads are connected to the lead protection mechanism 4 through the inlet 202. The lead protection mechanism 4 protects the lead connection, preventing damage from external factors during the test. Next, the air heater 201 is activated to heat the interior of the protective cover 2. Simultaneously, the blower mechanism 3 starts operating, evenly distributing the heat generated by the air heater 201 into the interior of the protective cover 2. This evaporates some of the moisture in the air inside the protective cover 2, while the remaining moisture condenses into water droplets inside. It is important to note the volume of the condensed water droplets. Extremely fine water droplets are continuously blown into the through-hole 102 by the blower mechanism 3, and then discharged through the through-hole 102, providing a dry testing environment for the high-voltage electrical components. After the environment inside the protective cover 2 is dry, the air heater 201 is turned off, and the blower mechanism 3 continues to blow air into the 2, so that the temperature inside the protective cover 2 drops faster. After the temperature inside the protective cover 2 drops to close to room temperature and remains stable, the withstand voltage tester 5 is started to begin the withstand voltage test on the high-voltage electrical components. During the test, the withstand voltage tester 5 will display the test data in real time so that the operator can understand the withstand voltage performance of the high-voltage electrical components in a timely manner.

[0023] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, multiple sets of support legs are symmetrically connected to both ends of the bottom of the operating table 1. The multiple sets of support legs are used to support the operating table 1 on the ground. A slot 101 is opened inside the top of the operating table 1 near the protective cover 2. The bottom of the protective cover 2 is movably engaged inside the slot 101. Multiple sets of through holes 102 are equidistantly arranged inside the top of the operating table 1 near the inner side of the slot 101. The shape of the multiple sets of through holes 102 at the top of the operating table 1 is set as funnel.

[0024] In practice, the funnel-shaped through-hole 102 can effectively collect the fine water droplets blown from inside the protective cover 2, preventing water droplets from accumulating on the top of the operating table 1 and affecting the testing environment. At the same time, anti-slip pads can be installed at the bottom of the support legs to enhance the stability of the operating table 1 and prevent the testing results from being affected by the shaking of the operating table 1 during the testing process. The material of the operating table 1 can be a material with good insulation properties to ensure the safety of the operator when performing withstand voltage testing. A sealing strip can be installed at the engagement point between the protective cover 2 and the slot 101 to further improve the sealing of the inside of the protective cover 2 and prevent external moisture from entering and affecting the dry testing environment.

[0025] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2As shown, a placement platform 103 is fixedly connected to the top of the operating table 1 near the top of the multiple sets of through holes 102 via multiple sets of mounting columns. The placement platform 103 is located inside the protective cover 2. An insulating pad is placed on the top of the placement platform 103. The placement platform 103 is used to place the high-voltage electrical components to be tested. There is a certain gap between the bottom of the placement platform 103 and the top of the operating table 1. An inclined cooling plate 104 is fixedly connected to the bottom of the operating table 1. The inclined cooling plate 104 is located below the multiple sets of through holes 102 and is made of metal.

[0026] In practice, the placement platform 103 is securely mounted above the operating table 1 and inside the protective cover 2 via multiple sets of mounting columns. This design facilitates the placement of high-voltage electrical components while ensuring they are in a relatively independent and safe space during testing. The insulating pad on top of the placement platform 103 effectively prevents potential safety hazards such as leakage caused by direct contact between the high-voltage electrical components to be tested and the placement platform 103, further ensuring the safety of the testing process. The gap between the bottom of the placement platform 103 and the top of the operating table 1 facilitates air circulation and prevents heat accumulation during testing. The inclined cooling plate 104, fixedly connected to the bottom of the operating table 1, has excellent thermal conductivity due to its metal material, which quickly conducts away the heat carried by the water droplets dripping from the through hole 102 and other heat generated during testing. The inclined design also allows the water droplets to flow down the cooling plate 104, preventing water droplets from accumulating on the cooling plate 104 and affecting the cooling effect.

[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 As shown, two sets of connectors 203 are fixedly connected to the symmetrical ends of one side of the outer wall of the protective cover 2. The interior of each set of connectors 203 is slidably connected to a sliding rod 204. The ends of each set of sliding rods 204 away from the connectors 203 are hinged to one side of the outer wall of the operating table 1 through a hinge. A handle is fixedly connected to the side wall of the protective cover 2 away from the inlet 202. The interior of the protective cover 2 is equipped with a temperature sensor and a humidity sensor for detecting the temperature and humidity of the interior space of the protective cover 2. The protective cover 2 is a transparent plastic cover.

[0028] In specific implementation, the protective cover 2 is slidably connected to the sliding rod 204 via the connector 203, and the sliding rod 204 is hinged to the outer wall of the operating table 1, thus enabling the protective cover 2 to be flexibly opened and closed above the operating table 1. When it is necessary to open or close the protective cover 2, the operator can first hold the handle and then pull the protective cover 2 upwards through the handle, so that the bottom of the protective cover 2 can disengage from the inside of the slot 101. At this time, the two sets of connectors 203 slide upwards synchronously on the two sets of sliding rods 204. Then, the operator rotates the protective cover 2. During the rotation, since the sliding rod 204 is hinged to the outer wall of the operating table 1, the protective cover 2 can be slid open and closed above the operating table 1. The protective cover 2 is connected by a hinge, so it can rotate around the hinge point, allowing it to open flexibly above the operating table 1. When it is necessary to close the protective cover 2 and the slot 101, the operator only needs to hold the handle and reverse the above steps to close the protective cover 2. At the same time, the temperature and humidity sensors installed inside the protective cover 2 can monitor the environmental parameters inside the protective cover 2 in real time, providing accurate environmental data support for the testing process. The choice of transparent plastic cover material ensures that the operator can clearly observe the situation inside the protective cover 2 during the testing process, ensuring the smooth progress of the testing.

[0029] It should be noted that the temperature sensor is model LM35 and the humidity sensor is model SHT45-AD1.

[0030] As one implementation method in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, the blower mechanism 3 includes first mounting brackets 301 fixedly installed at both symmetrical ends of the top of the protective cover 2. Two sets of first mounting brackets 301 are respectively located at both ends of the outer wall of the air heater 201. Rotating rods 302 are rotatably connected to the inner walls of the two sets of first mounting brackets 301. A blower 303 is fixedly connected between the two sets of rotating rods 302. The blower 303 is located above the air heater 201. A swing assembly 304 for driving the blower 303 to swing and rotate is provided on one side of the outer wall of one set of first mounting brackets 301. The output end of the swing assembly 304 is fixedly connected to the rotating rod 302 located on the inner wall of one set of first mounting brackets 301.

[0031] In practice, the oscillating assembly 304 drives the blower 303 to oscillate left and right, ensuring that the air blown by the blower 303 is evenly directed towards the air heater 201. This, in turn, allows the heated air, after being heated by the air heater 201, to be more evenly distributed within the protective cover 2, providing a more stable and uniform temperature environment for the withstand voltage testing of high-voltage electrical components. The blower 303 is rotatably connected to the first mounting bracket 301 via a rotating rod 302. This design ensures both the flexible oscillation of the blower 303 and the stability of its installation. In actual use, operators can adjust the oscillation amplitude and frequency of the blower 303 by adjusting the oscillating assembly 304 according to testing requirements, to meet the requirements for ambient temperature uniformity during withstand voltage testing of different high-voltage electrical components.

[0032] It should be noted that the rocking assembly 304 uses a starter motor as its power source, whose stable output provides a continuous and uniform driving force for the rotation of the shaft. Driven by the motor, the shaft rotates precisely, which in turn drives the rotating wheel to rotate according to a set trajectory and speed. The rotation of the rotating wheel drives the connected connecting rod, which performs a regular circular motion along with the rotation of the rotating wheel. Because the connecting rod is rotatably connected to one side of the outer wall of the rotating wheel, this connection method allows the connecting rod to flexibly adjust its angle during rotation. Simultaneously, the other end of the connecting rod is connected to a crank, and with the circular motion of the connecting rod, the crank... Driven by the connecting rod, the crank reciprocates, directly impacting the blower 303. This causes the blower 303 to oscillate above the air heater 201, ensuring that the air blown by the blower 303 evenly covers the air heater 201. This provides a stable and uniform temperature environment for the withstand voltage testing of high-voltage electrical components. A reducer is mounted on the motor's output shaft. The reducer effectively adjusts the motor's output speed to match the precise speed required for shaft rotation, ensuring the shaft rotates at a stable and appropriate speed. The reducer's adjustment prevents shaft instability caused by excessively fast or slow motor speeds, further ensuring the wheel rotates according to the set trajectory and speed, thus enabling the entire oscillating assembly to operate more precisely and stably.

[0033] The temperature sensor, humidity sensor, air heater 201, blower 303, and withstand voltage tester 5 are commercially available devices that can be purchased by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and are able to apply them proficiently. Thus, this paper will not elaborate further on these aspects. Furthermore, this solution aims to protect the physical structure, but does not protect the circuitry and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuitry technology.

[0034] It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0035] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 As shown, the lead wire protection mechanism 4 includes a first connecting cylinder 401 fixedly connected to the inner wall of the protective cover 2. One end of the first connecting cylinder 401 is connected to one end of the inlet 202. A limiting groove 402 is formed on the outer wall of the top of the first connecting cylinder 401. A threaded groove is formed on the side of the first connecting cylinder 401 away from the limiting groove 402. A first connecting ring 403 is fixedly connected inside the first connecting cylinder 401. The first connecting ring 403 is located on the inner wall of the first connecting cylinder 401 near the threaded groove. Multiple sets of first abutment blocks 404 are arranged in a ring on the inner side of the first connecting ring 403. The multiple sets of first abutment blocks 404 are conical in shape. The pointed conical ends of the multiple sets of first abutment blocks 404 are hinged to the inner wall of the first connecting ring 403 through multiple sets of frames. An arc-shaped clamping block 405 is fixedly connected to the bottom end of the multiple sets of first abutment blocks 404 away from the pointed conical end.

[0036] In practice, the material of the contact block 404 is soft plastic, while the materials of the arc-shaped clamping block 405 and the second contact block 409 are both hard plastic.

[0037] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 As shown, a lever 406 is slidably connected inside the limiting groove 402. The lever 406 is connected to the inner wall of the limiting groove 402 by a tension spring. A connecting rod 407 is fixedly connected to one end of the lever 406 near the inside of the first connecting cylinder 401. The connecting rod 407 is slidably inserted into the frame connecting one set of first abutment blocks 404 and the first connecting ring 403. A second connecting ring 408 is fixedly connected to the other end of the connecting rod 407 away from the lever 406. The surface of the second connecting ring 408 has a ring array of multiple sets of second abutment blocks 409. The shape of 09 is triangular. The number of multiple sets of second abutment blocks 409 and multiple sets of first abutment blocks 404 is the same. The multiple sets of second abutment blocks 409 are slidably sleeved on the outer wall of the multiple sets of first abutment blocks 404. The inclined surface of the multiple sets of second abutment blocks 409 slides in contact with the plane of the multiple sets of first abutment blocks 404. The end of the first connecting cylinder 401 away from the inlet 202 is rotatably fitted with a second connecting cylinder 410. The interior of the second connecting cylinder 410 is provided with a threaded groove. The connection between the second connecting cylinder 410 and the first connecting cylinder 401 is threaded through the threaded groove.

[0038] In practice, the first connecting cylinder 401 and the second connecting cylinder 410 are first separated. Then, the lead wire connected to the withstand voltage tester 5 passes through the inlet 202 sequentially through the first connecting cylinder 401, the first connecting ring 403, multiple sets of first contact blocks 404, multiple sets of arc-shaped clamping blocks 405, the second connecting ring 408, and the inner side of multiple sets of second contact blocks 409. The operator, wearing insulated gloves, pulls one end of the lead wire to connect with the lead wire of the high-voltage electrical component. When the withstand voltage tester 5 is connected to the lead wire of the high-voltage electrical component, the operator pulls the connected lead wire towards the inlet 202, placing the lead wire connector between the multiple sets of arc-shaped clamping blocks 405. At this time, the lever 406 is moved towards the inlet 202. The lever 406 slides along the limiting groove 402, simultaneously compressing the tension spring between the lever 406 and the inner wall of the limiting groove 402. The connecting rod 407 moves, which in turn moves the second connecting ring 408. The second connecting ring 408 then moves multiple sets of second contact blocks 409. As the inclined surfaces of the multiple sets of second contact blocks 409 slide in contact with the planes of the multiple sets of first contact blocks 404, during the movement of the second contact blocks 409, the multiple sets of second contact blocks 409 and the multiple sets of first contact blocks 404 cooperate with each other, causing the multiple sets of arc-shaped clamping blocks 405 to converge towards the lead wire connector, thereby firmly clamping the lead wire connector between the multiple sets of arc-shaped clamping blocks 405, completing the fixation of the lead wire connector. Then, the second connecting cylinder 410 and the first connecting cylinder 401 are re-threaded, providing a relatively closed and safe testing environment for the lead wire connector. This effectively prevents the connection from loosening due to external forces during subsequent withstand voltage testing, thus affecting the accuracy of the test results.

[0039] Working principle: First, the operator can hold the handle and pull the protective cover 2 upwards, allowing the bottom of the protective cover 2 to disengage from the slot 101. At this time, the two sets of connecting parts 203 slide upwards synchronously on the two sets of sliding rods 204. Then, the operator rotates the protective cover 2. During the rotation, since the sliding rods 204 are hinged to the outer wall of the operating table 1, the protective cover 2 can rotate around the hinge point, thus enabling the protective cover 2 to open flexibly above the operating table 1. The high-voltage electrical components are then placed on the 103 placement platform on the operating table 1. The first connecting cylinder 401 and the second connecting cylinder 410 are separated. Then, the lead wire connected to the withstand voltage tester 5 is passed sequentially through the inlet 202 through the inner sides of the first connecting cylinder 401, the first connecting ring 403, multiple sets of first abutment blocks 404, multiple sets of arc-shaped clamping blocks 405, the second connecting ring 408, and multiple sets of second abutment blocks 409. The operator, wearing insulated gloves, pulls out one end of the lead wire and connects it to the lead wire of the high-voltage electrical components. When the withstand voltage tester 5 is connected to the lead wire of the high-voltage electrical component, the operator pulls the connected lead wire towards the inlet 202, placing the lead wire connector between multiple sets of arc-shaped clamping blocks 405. At this time, the operator moves the lever 406 towards the inlet 202. The lever 406 slides along the limiting groove 402, simultaneously compressing the tension spring between the lever 406 and the inner wall of the limiting groove 402. The lever 406 drives the connecting rod 407 to move, the connecting rod 407 drives the second connecting ring 408 to move, and the second connecting ring 408 drives multiple sets of second... As the abutment block 409 moves, the inclined surfaces of multiple sets of second abutment blocks 409 slide in contact with the planes of multiple sets of first abutment blocks 404. During the movement of the second abutment block 409, the multiple sets of second abutment blocks 409 and multiple sets of first abutment blocks 404 cooperate with each other, causing multiple sets of arc-shaped clamping blocks 405 to converge towards the lead wire connector, thereby firmly clamping the lead wire connector between the multiple sets of arc-shaped clamping blocks 405, completing the fixation of the lead wire connector, and then re-threading the second connecting cylinder 410 and the first connecting cylinder 401.

[0040] Once the high-voltage electrical components are connected to the leads of the withstand voltage tester 5, the operator simply needs to reverse the steps of opening the protective cover 2 to close it. At this time, the air heater 201 is activated to heat the internal space of the protective cover 2. Then, the swing assembly 304 is activated to drive the blower 303 to swing left and right, so that the air blown by the blower 303 can be evenly blown towards the air heater 201. This allows the hot air heated by the air heater 201 to be more evenly distributed inside the protective cover 2. Some of the moisture in the air inside the protective cover 2 evaporates due to the heat, and the evaporated moisture condenses into water droplets inside the protective cover 2. These droplets are then released by the blower 303. The continuous blowing air carries water droplets into the through hole 102, where they are discharged, providing a dry testing environment for the high-voltage electrical components. Once the environment inside the protective cover 2 is dry, the air heater 201 is turned off, and the blower mechanism 3 continues to blow air into the cover 2 to accelerate the temperature drop inside. After the temperature inside the protective cover 2 drops to near room temperature and remains stable, the withstand voltage tester 5 is activated to begin withstand voltage testing on the high-voltage electrical components. During the testing process, the withstand voltage tester 5 displays the test data in real time, allowing operators to understand the withstand voltage performance of the high-voltage electrical components.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
