[0031] It also includes foot pads 2; the lower part of the protective frame 1 is detachably connected to two foot pads 2 on each of the left and right sides, and the lower part of the foot pads 2 is provided with a non-slip and wear-resistant silicone pad layer.

[0032] The working steps of the above embodiments are as follows:

[0033] First, the operator places the surge protector body 111 on the testing platform 4, with the ground terminal of the surge protector body 111 facing the second terminal block 10, and the neutral and live wire terminals of the surge protector body 111 facing the first terminal block 5. The first conductive copper posts 501 are arranged with positive and negative terminals, with the positive terminal connected to the live wire and the negative terminal connected to the neutral wire. The positive and negative first conductive copper posts 501 are arranged alternately. The first terminal block 5 has multiple independent first conductive copper posts 501, thus accommodating different models of surge protectors such as 1P / 2P / 4P. All surge protector bodies 111 can be tested. After the surge protector body 111 is accurately positioned, the operator activates the detector body 3, controlling the two first electric actuators 9 to retract, simultaneously moving the second terminal block 10 towards the first terminal block 5. As the second terminal block 10 contacts the surge protector body 111, the second conductive copper post 101 is also inserted into the grounding terminal of the surge protector body 111, moving the surge protector body 111 towards the first terminal block 5. The dustproof components on the first terminal block 5 are not tested. The first conductive copper post 501 is located within the enclosed space formed by the first terminal block 5, the movable plate 6, and the dustproof cloth 7. The dustproof sheet 8 with a cross-shaped notch also seals the wiring hole 601, thereby preventing dust and impurities from the external environment from adhering to the first conductive copper post 501 and causing abnormal discharge, or poor contact between the first conductive copper post 501 and the surge protector body 111, affecting the reliability of the performance test of the surge protector body 111. The surge protector body 111 contacts the movable plate 6, causing the movable plate 6 to move together, correspondingly... The elastic rod 502 is compressed, and at the same time, the first conductive copper post 501 passes through the corresponding wiring hole 601. The first conductive copper post 501 passes through the cross-shaped opening in the middle of the silicone dustproof sheet 8. The edge of the cross-shaped opening of the dustproof sheet 8 is attached to the first conductive copper post 501. As the surge protector body 111 continues to move, the first conductive copper post 501 of the positive and negative terminals are respectively inserted into the neutral wire terminal and the live wire terminal of the surge protector body 111, controlling the two first electric actuators 9 to stop. At this time, all the preparatory work before testing the surge protector body 111 is completed.

[0034] Then, the operator presses the test button on the detector body 3. The detector body 3 first applies an instantaneous nominal voltage to the first terminal block 5 through the two electrical contacts 13 on the left. This nominal voltage does not exceed 1000V for AC and 1500V for DC, thus simulating the surge protector body 111's surge protection performance against lightning strikes during thunderstorms. After the surge protector body 111 cools down to ambient temperature, the surge protector body can be directly observed by checking the display screen of the detector body 3. After the surge protector 111 withstands the nominal discharge current, it is determined whether it can maintain the voltage protection level. If the surge protector body 111 is tested normally, the instantaneous nominal voltage is applied to the first terminal block 5 again through the two electrical contacts 13 on the right. After the surge protector body 111 cools down to the ambient temperature, the display screen of the detector body 3 is checked. The positive and negative poles of the two electrical contacts 13 on the right are opposite to those of the two electrical contacts 13 on the left. By testing the surge protector body 111 with one positive and one negative pole, it is determined whether the surge protector body 111 meets the standard.

[0035] Because the surge protector body 111 is subjected to alternating positive and negative high-voltage surges, both the surge protector body 111 and the detector body 3 generating high-voltage electricity will generate a large amount of heat. In order to improve testing efficiency, efficient heat dissipation is required. The detector body 3 can dissipate heat through the dustproof nets on the left and right sides of the protective frame 1. At this time, the fan system 17 is activated, and external cooling air enters the air chamber 401 through the air hole 402. It flows through the surge protector body 111 to achieve forced convection heat dissipation. The hot air flows into the air chamber 401, and then the air enters the two guide chambers 403. With the cooperation of the fan 17, the heat is discharged to the external environment, thereby rapidly cooling the surge protector body 111 and preventing heat from accumulating inside the surge protector body 111. If the heat accumulates and cannot be dissipated in time, the surge protector body 111 will be easily broken down by high-voltage electricity, which will lead to damage to the surge protector body 111 and the detector body 3. This will not only affect the testing efficiency of the surge protector body 111, but also cause deviation in the test results.

[0036] Considering that the surge protector body 111 may experience poor thermal stability during testing, even with cooling by the fan 17, thermal runaway may still occur, potentially leading to spontaneous combustion. Therefore, during high-voltage impulse testing, if thermal runaway occurs in the surge protector body 111, the temperature sensor of the electric contact rod 13 will detect an abnormal temperature rise. This will then control all second electric actuators 14 to extend, simultaneously pulling one electric contact rod 13 out of the testing platform 4. Each electric contact rod 13 will then separate from one of the terminals 404. This disconnects the power to the testing station 4, thereby interrupting the testing process of the surge protector body 111. After the power is cut off, the first electric actuator 9 extends naturally, simultaneously driving the second terminal block 10 away from the first terminal block 5. At the same time, the surge protector body 111 no longer presses against the movable plate 6, and the elastic rod 502 returns to its original position. This causes the surge protector body 111 to move away from the first terminal block 5, and the first conductive copper column 501 exits from the terminal of the surge protector body 111. Then, the operator can remove the surge protector body 111 from the testing station 4, preventing the surge protector body 111 from spontaneously combusting and causing further damage to the testing station 4.

[0037] Second embodiment: Based on the first embodiment, according to Figures 1-6 As shown, it also includes an emergency airbag 15 and a telescopic column 16; the emergency airbag 15 is installed on the lower part of the testing platform 4; the lower part of the emergency airbag 15 is in contact with the protective frame 1; the protective frame 1 is connected to two telescopic columns 16 on each of the left and right sides; the telescopic column 16 is a spring telescopic rod; the telescopic parts of all the telescopic columns 16 are fixedly connected to the testing platform 4; all the telescopic columns 16 are set at the reserved hole position of the emergency airbag 15.

[0038] It also includes guide discs 12; each support plate 11 is fixedly connected to a guide disc 12; each guide disc 12 is slidably connected to an electric contact rod 13; all guide discs 12 are in contact with the testing table 4.

[0039] The contact area between the guide plate 12 and the testing table 4 is coated with grease. The edge of the guide plate 12 is provided with an annular flange to prevent jamming when the guide plate 12 and the testing table 4 move relative to each other, and to prevent the testing table 4 from being jammed by the guide plate 12 when it resets.

[0040] The working steps of the above embodiments are as follows:

[0041] Based on the first embodiment, when the power is cut off to the detection platform 4, the surge protector body 111 remains fixed to the detection platform 4. Only after the first electric actuator 9 automatically resets can the surge protector body 111 be removed from the detection platform 4. The detection platform 4 is located between the heated surge protector body 111 and the detector body 3. The electronic components inside the detection platform 4 are also easily affected by high temperatures. Therefore, in the event of thermal runaway, the power is cut off to the detection platform 4, and each electric contact rod 13 retracts to the corresponding guide plate 12. At this time, the emergency airbag 15 inflates and lifts the detection platform 4 upward. At the same time, all the telescopic columns 16 are stretched to prevent the detection platform 4 from tilting. This allows the detection platform 4 to be separated from the detector body 3 in an emergency, promoting heat dissipation between the detector body 3 and the surge protector body 111, avoiding heat accumulation in a localized area, and effectively providing emergency protection for the surge protector body 111, the detection platform 4, and the detector body 3.

[0042] After the surge protector body 111 cools to room temperature, the operator removes the surge protector body 111. At this time, the operator manually and slowly releases the gas in the emergency airbag 15, all the telescopic columns 16 return to their original positions, and the detection platform 4 is pulled down. When the detection platform 4 reaches the position of the guide plate 12 during its downward movement, the contact position between the guide plate 12 and the detection platform 4 is coated with grease, and the edge of the guide plate 12 is provided with an annular flange, which effectively prevents the guide plate 12 from jamming the reset detection platform 4, and can also effectively guide and limit the detection platform 4, making it easy for the detection platform 4 to reset. Thus, the emergency airbag 15 can be reused repeatedly, controlling the second electric actuator 14 to retract, and simultaneously making each electric contact rod 13 contact and cooperate with a power terminal 404, realizing the electrical connection between the detector body 3 and the detection platform 4, effectively increasing the service life of the equipment.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
