Simulation laboratories are the main places for simulating 10kV open-circuit grounding faults. In actual use, existing laboratories usually use ventilation equipment to ensure normal air circulation inside the laboratory. When using ventilation equipment, filters are used to filter the air. After long-term use, the filters need to be replaced. Since the filters are usually installed with bolts, disassembly and assembly are more troublesome, which is not conducive to quick replacement of the filters. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a 10kV open-circuit grounding fault simulation laboratory, which solves the problem that laboratories usually use ventilation equipment to ensure normal air circulation inside the laboratory. When the ventilation equipment is used, it uses filters to filter the air. After long-term use, the filters need to be replaced. Since the filters are usually installed with bolts, disassembly and assembly are more troublesome, which is not conducive to quick replacement of the filters.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a 10kV open-circuit grounding fault simulation laboratory, comprising a laboratory body, two air intake boxes installed on the laboratory body, an air intake fan fixedly connected to the inner wall of the air intake box, a louvered frame installed on one side of the air intake box, an air intake filter box located on the side of the air intake box away from the louvered frame, the air intake filter box fixedly connected to the top of the laboratory body, a mounting base located at the bottom of the air intake filter box, three air intake filters fixedly connected to the mounting base, the air intake filters being slidably connected to the inner wall of the air intake filter box, eight snap-fit ​​frames fixedly connected to the top of the laboratory body, the snap-fit ​​frames being grouped in sets of four, two springs located on the inner wall of each snap-fit ​​frame, a snap-fit ​​block installed at one end of each spring, the snap-fit ​​block abutting against the mounting base.

[0005] As a further embodiment of this utility model: an air inlet main pipe is installed on the side of the air inlet filter box away from the air inlet box, and several air supply pipes are provided under the air inlet main pipe. The air supply pipes are fixedly connected to the top of the laboratory body. Several rubber clips are installed on both sides of the mounting base and the air inlet filter screen. The rubber clips are slidably connected to the laboratory body and the air inlet filter box.

[0006] As a further embodiment of this utility model: eight air outlet branch pipes are installed on the bottom of both sides of the main body of the laboratory. One end of each of the eight air outlet branch pipes is connected to the same main air outlet pipe. Both ends of the main air outlet pipe are equipped with air outlet filter boxes, and the air outlet filter boxes are fixedly connected to the main body of the laboratory.

[0007] As a further embodiment of this utility model: a plug-in seat is provided on one side of the air outlet filter box, and an air outlet filter screen is installed on one side of the plug-in seat, and the air outlet filter screen is slidably connected to the inner wall of the air outlet filter box.

[0008] As a further embodiment of this utility model: an air outlet box is fixedly connected to one side of the air outlet filter box, an air outlet fan is fixedly connected to the inner wall of the air outlet box, and several baffles are provided on the side of the air outlet box away from the air outlet filter box.

The pulleys are slidably connected to the bottom of the storage groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This 10kV open-circuit grounding fault simulation laboratory uses a mounting base, spring, snap-fit ​​block, and air inlet filter. When disassembling the air inlet filter, pressing the snap-fit ​​block retracts it into the snap-fit ​​frame, thus releasing the mounting base's restraint. Pulling the mounting base causes the air inlet filter to detach from the air inlet filter box, enabling rapid disassembly. When assembling the air inlet filter, aligning the mounting base with the slot at the top of the laboratory body and inserting it, the mounting base simultaneously presses the snap-fit ​​block, retracting it into the snap-fit ​​frame. Simultaneously, the spring between the snap-fit ​​frame and the snap-fit ​​block is compressed, generating relative elastic force. After the mounting base enters the laboratory body, releasing the pressure on the snap-fit ​​block allows the spring to reset through its elastic force, restraining the mounting base. This allows for rapid assembly of the air inlet filter on the mounting base, improving the efficiency of air inlet filter replacement.

[0012] 2. This 10kV open-circuit grounding fault simulation laboratory is equipped with an intake fan, an air supply duct, an exhaust branch duct, and an exhaust fan. The intake fan draws outside air into the inner wall of the intake duct, and then into the main body of the laboratory through the air supply duct below the intake duct. At the same time, it draws the air in the main body of the laboratory to the bottom of the laboratory. As the air in the main body of the laboratory flows downward, it can enter the exhaust branch duct and be discharged outward by the exhaust fan, ensuring that there is enough fresh air in the laboratory.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5As shown, this utility model provides a technical solution: a 10kV open-circuit grounding fault simulation laboratory, including a laboratory body 1, a laboratory protective wall 22 installed outside the laboratory body 1, a storage groove 25 opened on the bottom of one side of the laboratory protective wall 22, a sliding door 23 slidably connected to the inner wall of the laboratory body 1, and several pulleys 24 movably connected under the sliding door 23. The pulleys 24 are slidably connected to the bottom of the storage groove 25. By setting the pulleys 24, when the sliding door 23 is moving, the pulleys 24 under the sliding door 23 can slide inside the storage groove 25, thereby facilitating the opening and closing of the sliding door 23;

[0021] Eight air outlet branch pipes 14 are installed on both sides of the bottom of the main laboratory 1. One end of each of the eight air outlet branch pipes 14 is connected to the same main air outlet pipe 15. Both ends of the main air outlet pipe 15 are equipped with air outlet filter boxes 16. The air outlet filter boxes 16 are fixedly connected to the main laboratory 1. A plug-in socket 17 is provided on one side of the air outlet filter box 16. An air outlet filter 18 is installed on one side of the plug-in socket 17. The air outlet filter 18 is slidably connected to the inner wall of the air outlet filter box 16. By setting the air outlet filter 18, when the air is discharged through the air outlet filter box 16, the air passes through the air outlet filter 18, so that the air outlet filter 18 can filter the air, thereby treating the harmful gases inside the laboratory before being discharged from the laboratory, avoiding the harmful gases discharged from the laboratory from polluting the outside air.

[0022] An air outlet box 19 is fixedly connected to one side of the air outlet filter box 16. An air outlet fan 20 is fixedly connected to the inner wall of the air outlet box 19. Several baffles 21 are provided on the side of the air outlet box 19 away from the air outlet filter box 16. By setting the baffles 21, the baffles 21 can isolate the inside of the air outlet box 19 from the outside, thereby protecting the air outlet fan 20 inside the air outlet box 19.

[0023] Two air intake boxes 2 are installed on the main body of the laboratory. An air intake fan 3 is fixedly connected to the inner wall of the air intake box 2. A louvered frame 4 is installed on one side of the air intake box 2. By setting the louvered frame 4 on one side of the air intake box 2, the air intake box 2 is isolated from the outside world, thereby reducing the entry of external dust into the air intake box 2 and reducing the filtration pressure of the air intake filter 7.

[0024] An air intake filter box 5 is installed on the side of the air intake box 2 away from the louvered frame 4. The air intake filter box 5 is fixedly connected to the top of the laboratory body 1. An installation seat 6 is installed at the bottom of the air intake filter box 5. Three air intake filters 7 are fixedly connected to the installation seat 6. The air intake filters 7 are slidably connected to the inner wall of the air intake filter box 5. Eight snap-fit ​​frames 10 are fixedly connected to the top of the laboratory body 1. The snap-fit ​​frames 10 are in groups of four. Two springs 11 are installed on the inner wall of each snap-fit ​​frame 10. A snap-fit ​​block 12 is installed at one end of the spring 11. The snap-fit ​​block 12 abuts against the installation seat 6. By setting the springs 11, when the installation seat 6 enters the bottom of the air intake filter box 5 and inserts into the air intake filter box 5, the installation seat 6 will squeeze the snap-fit ​​block 12, causing the snap-fit ​​block 12 to move into the snap-fit ​​frame 10, thereby squeezing the springs 11 inside the snap-fit ​​frame 10. This causes the springs 11 to generate relative elastic force, which facilitates the subsequent reset of the snap-fit ​​block 12 by the spring force to limit the installation seat 6.

[0025] An air intake main pipe 8 is installed on the side of the air intake filter box 5 away from the air intake box 2. Several air supply pipes 9 are installed under the air intake main pipe 8. The air supply pipes 9 are fixedly connected to the top of the laboratory body 1. Three rubber clips 13 are installed on both sides of the mounting base 6 and the air intake filter screen 7. The rubber clips 13 are slidably connected to the laboratory body 1 and the air intake filter box 5. By setting the rubber clips 13, after the mounting base 6 is inserted into the air intake filter box 5, the rubber clips 13 are deformed by squeezing with the air intake filter box 5, thereby increasing the friction between them and the air intake filter box 5, and clamping the mounting base 6 tightly to the bottom of the air intake filter box 5.

[0026] The working principle of this utility model is as follows:

[0027] During operation, both the intake fan 3 and the exhaust fan 20 are started simultaneously. The intake fan 3 draws outside air towards the intake filter box 5. After being filtered by the intake filter 7 on the inner wall of the intake filter box 5, the air enters the main intake pipe 8 and then flows into the laboratory main body 1 through the air supply pipe 9 below the main intake pipe 8. The exhaust fan 20 draws air from inside the laboratory main body 1 towards the exhaust branch pipe 14. The air then enters the main exhaust pipe 15 through the exhaust branch pipe 14 and is filtered by the exhaust filter box 16 on one side of the main exhaust pipe 15 before being discharged from the laboratory main body 1, thus achieving air circulation inside the laboratory main body 1. When it is necessary to replace the intake filter 7 in the intake filter box 5, the corresponding intake fan 3 is turned off, while the other intake fan 3 continues to operate. The airflow inside the main body 1 is facilitated by pressing the latching block 12, causing it to retract into the latching frame 10, thus releasing the latching block 12 from limiting and fixing the mounting base 6. Then, the mounting base 6 is pulled to detach the air inlet filter 7 from the air inlet filter box 5. The new air inlet filter 7 is aligned with the through groove under the air inlet filter box 5 and inserted into the through groove. As the mounting base 6 moves, it presses the latching block 12, allowing it to retract into the latching frame 10. At the same time, it compresses the spring 11, causing the spring 11 to generate elastic force. After the air inlet filter 7 is completely inside the air inlet filter box 5, the mounting base 6 releases the pressure on the latching block 12, and the spring 11 drives the latching block 12 to reset and limit the mounting base 6, thus completing the installation and removal of the air inlet filter 7.
