An activated carbon plate is provided inside the treatment box 203. During the suction operation, the suction pump 201 operates under the power supply and controller to extract the gas from the detection chamber 101 and inject it into the treatment box 203 through the gas pipe 202. The activated carbon plate in the treatment box 203 can filter and adsorb the odors and harmful gases in the gas.

[0023] refer to Figure 1 , Figure 2 Voltage component 3 is used to provide a controllable voltage to the upper electrode 304; voltage component 3 includes a transformer 301, a voltage controller 302, and a voltmeter 303; the transmission terminal of the transformer 301 is electrically connected to the upper electrode 304. The voltage controller 302 is used to control the voltage output of the transformer 301, and the voltmeter 303 is used to display the real-time voltage value.

[0024] refer to Figure 2 , Figure 6 , Figure 7 Lifting assembly 6 provides lifting function; lifting assembly 6 includes an electric push rod 601 fixedly installed on the detection chamber 101, the output end of the electric push rod 601 is fixedly connected to a lifting plate 602, a guide rod 603 is fixedly connected between the detection chamber 101 and the lower protective chamber 4, the guide rod 603 passes through the lifting plate 602 and is slidably engaged with each other, and a lower insulating plate 604 is fixedly connected to the lifting plate 602; During lifting operations, the electric push rod 601 operates under the control of an external power supply and controller, driving the lifting plate 602 to rise or fall, thereby driving the lower electrode assembly 5 and the product on the lower insulating plate 604.

[0025] refer to Figure 1 , Figure 8 The lower protective chamber 4 is located below the detection chamber assembly 1 and is used to provide insulation protection. The top of the lower protective chamber 4 is provided with a receiving notch 401, through which the lower conductive post 502 can pass. The lower protective chamber 4 is made of insulating material to isolate the space and prevent the lower conductive column 502 from being damaged by accidental contact.

[0026] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The lower electrode assembly 5 is mounted on the lifting component of the lifting assembly 6 and is used to provide the product placement position and automatically center the product. The lower electrode assembly 5 includes a lower electrode base 501, a lower conductive post 502 fixedly connected to the lower part of the lower electrode base 501, a moving groove 5011 provided in the lower electrode base 501, a pusher 503 slidably connected in the moving groove 5011, a lifting post 509 slidably connected at the center of the lower electrode base 501, a center plate 505 fixedly connected to the lower end of the lifting post 509, a spring 506 provided below the center plate 505, a bottom plate 507 provided below the spring 506, and a spring piece 504 fixedly connected between the center plate 505 and the pusher 503. A contact wheel 508 is provided in the lower electrode base 501, and the contact wheel 508 contacts the pusher 503. An arc portion 5012 is provided on the side of the moving groove 5011 near the lifting post 509. When placing the product, such as a rubber insulating board, the product will press down on the lifting column 509 due to its own weight. The lifting column 509 moves downward against the elastic force of the spring 506. The center plate 505 drives the pusher 503 to move through the spring 504. The pusher 503 moves radially from the outside to the center, pushing the product towards the center. The product is automatically placed in the center. A product placed in the center can ensure that the electric field distribution of the upper electrode 304 is uniform. If the electric field distribution is uneven, edge effects will occur, resulting in electric field distortion and causing deviations in parameters such as breakdown voltage. Only by placing the upper electrode 304 in the center can a more uniform electric field distribution be obtained, thereby obtaining more accurate test data. When the product is removed, the spring force of the compressed spring 506 can drive the lifting column 509 to move upward again. The upward movement of the center plate 505 will drive the spring 504 to move. The spring 504 will drive the pusher 503 to move outward along the radius, which can automatically release the product. The pusher 503 has an L-shaped longitudinal section, with the upper part of the pusher 503 being higher than the upper surface of the lower electrode seat 501 to ensure that the product can be pushed; the contact wheel 508 is used to reduce the friction between the pusher 503 and the lower electrode seat 501.

[0027] This invention also provides an intelligent testing method for the performance of rubber insulation products, which uses the aforementioned intelligent testing device for the performance of rubber insulation products and includes the following steps: Step 1: Place the product to be tested on the lower electrode assembly 5. The lower electrode assembly 5 provides the product placement position and automatically centers the product. Specifically: when the product is placed in, due to the weight of the rubber insulation board itself, the product will press the lifting column 509. The lifting column 509 overcomes the elastic force of the spring 506 and moves downward. The center plate 505 drives the pusher 503 to move through the spring piece 504. The pusher 503 moves from the outside to the center side in the radial direction, pushing the product towards the center. The product is automatically placed in the center. Step 2: The lifting component 6 drives the product to move; The electric push rod 601 operates under the action of the external power supply and controller, driving the lifting plate 602 to rise, thereby driving the lower electrode assembly 5 on the lower insulating plate 604 and the product to move upward, and the product and the lower electrode assembly 5 enter the testing chamber 101; Step 3: Power on the product to test its breakdown voltage; When an external power source is supplied, the voltage is boosted by transformer 301. Voltage controller 302 controls the voltage output of transformer 301, and voltmeter 303 displays the real-time voltage value. Once the product is broken down, the breakdown voltage value can be obtained.

[0028] Example 2: refer to Figure 9 , Figure 10 The difference from implementation one is that: the lower electrode seat 501 is provided with a relief component 7, the relief component 7 includes a receiving groove 701 on the upper surface of the lower electrode seat 501, a gas cavity 702 in the lower electrode seat 501, a piston 703 slidably connected to the upper part of the gas cavity 702, a central cavity 707 in the lifting column 509, a lower air port 708 and an upper air port 706 on the circumferential surface of the lifting column 509, a main air passage 704 and a branch air passage 705 that are interconnected in the lower electrode seat 501, the main air passage 704 is used to connect the gas cavity 702 and the lower air port 708, the upper opening of the branch air passage 705 is arranged between the lower air port 708 and the upper air port 706, and the friction between the piston 703 and the gas cavity 702 can support the piston 703; The design of the release component 7 is to slow down the falling speed of the tested product. For example, a rubber insulation board product with a thickness of 12 mm is placed on the piston component 703. The upper part of the piston component 703 has a flat surface and is higher than the lifting column 509. The number of release components 7 can be four. When the product is initially placed, the weight of the product is greater than the friction between the piston component 703 and the gas chamber 702. The piston component 703 is slowly pressed down, and the piston component 703 discharges the gas in the gas chamber 702 from the main air channel 704, the lower air port 708, the central cavity 707, and then from the upper air port 706. Since the orifice of the main air channel 704 is small, the piston component 703 will slowly descend. At this time, the product is randomly placed and is in a non-centered offset state. When testing, the breakdown voltage value of the product at the non-centered position can be detected, which is suitable for the testing needs of multiple different positions. When the piston 703 and the lifting column 509 are aligned, the lifting column 509 is also driven downward by gravity. Due to the downward movement of the lifting column 509, the air distribution channel 705 will be connected to the upper air port 706. At this time, there are two exhaust channels: the main air channel 704 and the air distribution channel 705. Therefore, the exhaust volume increases and the centering operation of the first embodiment is quickly performed. When the product is tested after centering, the breakdown voltage value of the product at the center position is detected. The product breakdown voltage value at different positions can be measured when the product is placed once. It does not require manual adjustment of the product position multiple times, which is very suitable for the need to measure the product breakdown value multiple times. To prevent the piston 703 from falling due to its own weight, the piston 703 can be hollow. Since the detection of breakdown voltage requires conductivity, the piston 703 can be made of conductive material to ensure that the material on the piston 703 can also meet the detection requirements. To reasonably control the release duration, the main air passage 704 and the branch air passage 705 with different orifice diameters can be selected according to the release duration. To ensure that the distance between the upper electrode 304 and the product is appropriate, the movement stroke of the electric push rod 601 needs to be precisely controlled. Therefore, a servo-driven electric push rod 601 can be used. The movement stroke of the electric push rod 601 is consistent with the speed at which the product falls and falls on the piston 703. The distance can be detected by a distance sensor to detect the position of the product in real time.
