Description

Technical Field

[0001] This utility model relates to the field of lightning surge detection technology, specifically to a detection device for lightning surge generator experiments. Background Technology

[0002] A surge is a violent pulse that occurs in a fraction of a second. Potential causes of surges include heavy equipment, short circuits, power switching, or large motors. Products containing surge protection devices can effectively absorb sudden bursts of energy, protecting connected equipment from damage. Lightning surge generator testing equipment primarily serves to evaluate the performance of power lines and internal wiring in electrical and electronic equipment when subjected to high-energy transient interference from switches and natural lightning strikes.

[0003] Existing testing equipment for lightning surge generator experiments typically involves placing the device directly in a fixed location and then electrically connecting it to the power supply and the device under test to ensure normal operation. However, during actual use, the device generates high-voltage current internally, and its casing easily accumulates static electricity. If placed directly on a table, this static electricity may cause the table to break down, resulting in an accidental electric shock. Therefore, we propose a testing device for lightning surge generator experiments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a testing device for lightning surge generator experiments. It solves the problem that during actual use, the device generates high-voltage current inside the device during testing, and the outer casing of the device easily accumulates static electricity. If placed directly on a table, the static electricity may break through the table and cause an accidental electric shock.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A testing device for lightning surge generator experiments includes a housing, a base fitted on the bottom surface of the housing, a mounting block fixedly installed on one side of the base, a mounting hole on the top surface of the mounting block, a snap-fit ​​block being engaged inside the mounting hole, the snap-fit ​​block consisting of a cylindrical part and two disc parts at both ends, and a metal strip fixedly installed on the bottom surface of the bottom disc part of the snap-fit ​​block.

[0006] Preferably, a plurality of fixing feet are fixedly installed on the bottom surface of the housing, and two snap-fit ​​rings are fixedly installed on the outer wall surface of the fixing feet. A rubber sleeve is provided on the outer wall surface of the fixing feet, and the rubber sleeve is snapped together with the fixing feet by the two snap-fit ​​rings.

[0007] Preferably, an upper partition plate is fixedly installed inside the box, and a lower partition plate is fixedly installed inside the box.

[0008] Preferably, a plurality of placement plates are fixedly installed inside the enclosure, an electrical box is housed inside the enclosure, and a lightning surge generator body is housed inside the enclosure. The electrical box and the lightning surge generator body are respectively located on the top surface of different placement plates.

[0009] Preferably, a low-voltage signal interface conversion box is provided inside the enclosure, and a high-voltage signal interface conversion box is provided inside the enclosure, with the low-voltage signal interface conversion box and the high-voltage signal interface conversion box located on the top surface of different placement plates, respectively.

[0010] Preferably, a plurality of through holes are provided on one side of the box body, and a box door is provided on one side of the box body. The box door is connected to the box body by a hinge, and a storage cabinet is installed inside the box body. The storage cabinet is located on the top surface of the lower partition plate.

[0011] In summary, the present invention has the following main advantages: 1. By setting up a snap-fit ​​block, the snap-fit ​​block and metal strip design can be disassembled as needed. When not in use or when the device is stored, they can be removed and stored separately to avoid redundancy of the device body. The metal material of the metal strip needs to be in contact with the ground during use. When static electricity is generated on the surface of the device due to the internal current, it can quickly conduct the static electricity to the ground to avoid injury to workers or accidental fire caused by electric sparks. 2. By setting fixed feet, the contact area between the device and the fixed position can be reduced while ensuring stability. Combined with the design of the rubber sleeve, it can block the static electricity of the outer shell and prevent high-intensity static electricity from damaging the fixed position.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] refer to Figures 1-3 A testing device for lightning surge generator experiments includes a housing 1. A base 2 is fitted on the bottom surface of the housing 1. An mounting block 3 is fixedly installed on one side of the base 2. An mounting hole 4 is opened on the top surface of the mounting block 3. A snap-fit ​​block 5 is snapped into the inside of the mounting hole 4. The snap-fit ​​block 5 consists of a cylindrical part and two disc parts at both ends. A metal strip 6 is fixedly installed on the bottom surface of the bottom disc part of the snap-fit ​​block 5. Through the design of the snap-fit ​​block 5 and the metal strip 6, the snap-fit ​​design allows the entire assembly of the snap-fit ​​block 5 and the metal strip 6 to be disassembled at any time as needed. When not in use or when the device is stored, it can be removed and stored separately to avoid redundancy of the device body. The metal material of the metal strip 6 needs to be in contact with the ground during use. When static electricity is generated on the surface of the device due to the internal current, it can quickly conduct the static electricity to the ground to avoid injury to the staff or accidental fire caused by electric sparks. Several fixing feet 7 are fixedly installed on the bottom surface of the housing 1. Two snap-fit ​​rings 8 are fixedly installed on the outer wall of the fixing feet 7. A rubber sleeve 9 is provided on the outer wall of the fixing feet 7. The rubber sleeve 9 is snapped together with the fixing feet 7 through the two snap-fit ​​rings 8. Through the design of the fixing feet 7, the contact area between the device and the fixed position can be reduced while ensuring stability. In conjunction with the design of the rubber sleeve 9, the static electricity of the outer shell can be blocked, avoiding damage to the fixed position caused by high-intensity static electricity. An upper partition plate 10 is fixedly installed inside the box 1, and a lower partition plate 11 is fixedly installed inside the box 1. Through the design of the upper partition plate 10 and the lower partition plate 11, the space above the upper partition plate 10 and the space below the lower partition plate 11 can be reserved. On the one hand, it can avoid the internal electrical components from being in too close contact with the box 1 and reduce the accumulation of static electricity on the outer wall of the box 1. On the other hand, it can provide sufficient operating space for the staff to maintain and replace, making the operation of the staff more convenient. The enclosure 1 has several placement plates 12 fixedly installed inside. An electrical box 13 is housed inside the enclosure 1, and a lightning surge generator body 14 is housed inside the enclosure 1. The electrical box 13 and the lightning surge generator body 14 are located on the top surface of different placement plates 12. The electrical box 13 and the lightning surge generator body 14 are both commercially available structures. The electrical box 13 contains a leakage current protector and a surge protector, which can provide bidirectional protection for electrical components and personnel, that is, to prevent electrical components from being damaged by high voltage and to prevent electric shock accidents. The lightning surge generator body 14 can serve as the main body of the device, generating high voltage and evaluating the condition of electrical components after receiving high voltage, thereby achieving the effect of lightning strike detection. The enclosure 1 contains a low-voltage signal interface conversion box 15 and a high-voltage signal interface conversion box 16. The low-voltage signal interface conversion box 15 and the high-voltage signal interface conversion box 16 are located on the top surface of different placement plates 12. The low-voltage signal interface conversion box 15 and the high-voltage signal interface conversion box 16 are both existing structures on the market. They are mainly used for testing the device. Before using the lightning surge generator body 14, the rubber socket of the lightning surge generator body 14 needs to be connected to the rubber plug of the high-voltage signal interface conversion box 16 through the adapter wire while the power is off. The low-voltage signal interface conversion box 15 is also used in the same way to ensure that the lightning surge generator body 14 can operate normally. Several through holes are provided on one side of the enclosure 1. These through holes serve as heat dissipation points for the enclosure 1, ensuring that the heat generated by the electrical components inside the enclosure 1 can be exchanged with the outside through them, thus avoiding safety hazards caused by excessive heat accumulation. A door 17 is provided on one side of the enclosure 1, which is connected to the enclosure 1 by a hinge. A storage cabinet 18 is installed inside the enclosure 1. The storage cabinet 18 is located on the top surface of the lower partition plate 11. Through the design of the storage cabinet 18, it can serve as a storage device to store various adapters required by the device, collect them centrally to avoid loss of adapters, and avoid affecting the electrical connection of the device and other electrical components.
