[0002] Indoor power box, also known as indoor power distribution cabinet, refers to equipment installed inside a building for centralized power supply and distribution. It is usually made of metal or plastic and is used to install and protect power distribution equipment such as circuit breakers, fuses, contactors, etc. Indoor power box is usually connected to the main power line of the building to distribute power to various rooms and equipment. The indoor power box distributes the power of the main power line to various branch lines and electrical equipment to realize the power supply inside the building. The indoor power box protects the circuit from overload by installing circuit breakers, fuses and other equipment to prevent overload damage to electrical equipment. When a short circuit occurs in the circuit, the indoor power box can protect the safety of electrical equipment and buildings by automatically disconnecting the power supply. The indoor power box ensures that both equipment and personnel in the circuit can be effectively grounded to reduce the risk of electric shock.

[0003] The research on harmonic current test technology of mains power supply equipment refers to the technical research on testing and analyzing the harmonic current generated by mains power supply equipment in actual operation. In the power system, mains power supply equipment such as transformers, generators, cables, etc. will be affected by harmonic currents during operation. These harmonic currents may cause problems such as equipment overheating, damage, and even system instability. The purpose of the harmonic current test technology research is to understand the harmonic current characteristics of mains power supply equipment under different working conditions through experiments and tests, including harmonic frequency, amplitude, phase and other information. By testing and studying harmonic currents, the tolerance of equipment to harmonics can be evaluated, and corresponding protection and improvement measures can be formulated to ensure the safe and stable operation of equipment and systems. During the experiment, various detection instruments are set inside the experimental plant. Therefore, a power box for power distribution to the test instruments is set inside the experimental plant. Due to the large number of experimental equipment in the plant, the electronic components in the power box are under heavy load and generate more heat, so there is a greater fire hazard. The power box in the prior art has a simple structure and cannot effectively control the fire in time after a fire occurs, which poses certain safety hazards.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] An indoor power supply box structure, such as Figure 1 As shown, it includes a box body 1, a box door 2 and a fireproof sealing component 4; the box door 2 is hinged to the box body 1, and heat dissipation windows 3 are arranged on both sides of the box body 1 near the bottom, and the fireproof sealing component 4 is arranged in the box body 1 and corresponds to the position of the heat dissipation windows 3; wherein, the heat dissipation windows 3 on both sides of the box body 1 are used to ventilate the box body 1, and take away part of the heat in the box body 1 through ventilation, thereby reducing the possibility of fire.

[0031] like Figures 2 to 5 As shown, the fireproof sealing assembly 4 includes a mounting plate 406, a guide slider 405, a connecting plate 407, a positioning trigger 401, a bottom plate 410, a sealing plate 408, a connecting head 411, a connecting tube 413 and a compression spring 412;

[0032] The mounting plate 406 is fixedly connected to the inner wall of the box 1, and a guide groove 404 is provided on the mounting plate 406. The guide slider 405 is slidably connected in the guide groove 404, and the connecting plate 407 is fixedly connected to the guide slider 405; one end of the positioning trigger 401 is connected to the connecting plate 407, and the other end is connected to the inner wall of the box 1; the bottom plate 410 is fixedly connected to the connecting plate 407, the connecting head 411 is fixedly connected to the bottom plate 410, and the connecting tube 413 is fixedly connected to the sealing plate 408; one side of the connecting head 411 is movably connected in the connecting tube 413, and the two ends of the compression spring 412 are respectively connected to the connecting head 411 and the connecting tube 413. Among them, the positioning trigger 401 is used to pull the connecting plate 407 so that the connecting plate 407, the bottom plate 410 and the sealing plate 408 are located above the heat dissipation window 3.

[0033] In actual use, when a fire occurs in the box body 1, an open flame is generated in the box body 1, and the open flame burns the positioning fuse 401. After the positioning fuse 401 is burned, the connecting plate 407, the bottom plate 410 and the sealing plate 408 move downward. In this process, the guide slider 405 can correct the posture of the connecting plate 407 to prevent the connecting plate 407 from getting stuck. When the guide slider 405 contacts the bottom of the guide groove 404, the connecting plate 407, the bottom plate 410 and the sealing plate 408 also move to the bottom. At this time, the sealing plate 408 can block the heat dissipation window 3, so that the box body 1 cannot be supplemented with oxygen, so that the fire gradually decreases and extinguishes, and the fire can be effectively controlled. The connector 411, the connecting tube 413 and the compression spring 412 between the bottom plate 410 and the sealing plate 408 are to enable the sealing plate 408 to be close to the inner wall of the box body 1, so as to ensure that the sealing plate 408 can stably block the heat dissipation window 3.

[0034] In a preferred embodiment, the guide groove 404 is a cross structure, and the guide slider 405 is a cross structure and matches the guide groove 404. The guide groove 404 and the guide slider 405 of this structure can ensure stability and prevent the guide slider 405 from getting stuck in the guide groove 404, that is, it is ensured that the connecting plate 407, the bottom plate 410 and the sealing plate 408 can quickly move to the bottom and block the heat dissipation window 3 after being triggered.

[0035] In a preferred embodiment, Figure 2 As shown, a tension spring 403 is provided in the guide groove 404, one end of the tension spring 403 is fixedly connected to the bottom wall of the guide groove 404, and the other end is fixedly connected to the guide slider 405. The tension spring 403 is provided to provide a certain initial force. Since a connector 411, a connecting tube 413 and a compression spring 412 are provided between the bottom plate 410 and the sealing plate 408, the compression spring 412 pushes the sealing plate 408 against the inner wall of the box body 1, and the friction between the sealing plate 408 and the inner wall of the box body 1 is relatively large; the process of the connection plate 407, the bottom plate 410 and the sealing plate 408 descending will be relatively slow. After the tension spring 403 is provided, the tension spring 403 can assist the guide slider 405 to move downward, that is, to assist in driving the connection plate 407, the bottom plate 410 and the sealing plate 408 to descend.

[0036] In a preferred embodiment, Figures 2 to 5As shown, a positioning head 409 is fixedly connected to the middle of the mounting plate 406, and one end of the positioning trigger 401 is connected to the inner wall of the box body 1, and the other end is connected to the positioning head 409. More specifically, a hole is provided on the positioning head 409, and this design allows for convenient connection of the positioning trigger 401. Further optimized, the positioning trigger 401 is made of flammable fiber material; at least three positioning triggers 401 are provided. The positioning trigger 401 is made of flammable fiber material in order to enable a quick response after a fire occurs in the box body 1. At least three positioning triggers 401 are provided for safety reasons to prevent the positioning trigger 401 from breaking naturally and affecting the ventilation of the box body 1.

[0037] In a preferred embodiment, if Figure 2 As shown, at least three groups of connectors 411 and connecting tubes 413 are provided between the bottom plate 410 and the sealing plate 408. By providing multiple groups of connectors 411 and connecting tubes 413, the stability between the bottom plate 410 and the sealing plate 408 can be ensured, and the sealing plate 408 can be prevented from shaking.

[0038] In a preferred embodiment, if Figure 3 As shown, a sealing gasket 414 is provided on one side of the sealing plate 408 away from the bottom plate 410. The sealing gasket 414 is used to be close to the inner wall of the box body 1 to improve the sealing effect.

[0039] In a preferred embodiment, if Figures 4 to 5 As shown, a limiting shell 418 is fixedly connected to the bottom plate 410, and a card interface 415 is provided on the side of the limiting shell 418 close to the sealing plate 408; an elastic limiting head 417 is fixedly connected to the sealing plate 408, and a card connection portion 419 is provided at the end of the limiting head; the end of the elastic limiting head passes through the card connection portion 415 and is carded with the limiting shell 418 through the card connection portion 419, and the two sides of the bottom of the box body 1 are fixedly connected with the positioning plate 402, which is used to extend into the limiting shell 418 and push the elastic limiting head 417 to deform. Specifically, the setting of the limiting head and the limiting shell 418 allows the sealing plate 408 to avoid contact with the inner wall of the box body 1 when it is not lowered, specifically, the card connection portion 419 on the limiting head cooperates with the card interface 415 of the limiting shell 418. After a fire occurs, the connecting plate 407, the bottom plate 410 and the sealing plate 408 are triggered and move downward, and the positioning plate 402 is inserted into the limiting shell 418. The positioning plate 402 pushes the elastic limiting head 417 to deform, thereby disconnecting the clamping relationship between the clamping portion 419 and the clamping interface 415, and the sealing plate 408 pops outward and contacts the inner wall of the box body 1, thereby ensuring the sealing.

[0040] In a preferred embodiment, if Figures 4 to 5As shown, the upper portion of the limiting shell 418 is fixedly connected to the outer side of the card interface 415 with a limiting cylinder 416. The limiting cylinder 416 is designed to facilitate the elastic limiting head 417 to be inserted into the limiting shell 418.

[0041] In a preferred embodiment, Figures 4 to 5 As shown, an inclined surface is provided at the end of the positioning plate 402. The inclined surface at the end of the positioning plate 402 is for the purpose of contacting with the elastic stopper 417 and causing the elastic stopper 417 to deform.
