[0002] High-voltage and low-voltage switchgear are core equipment in power supply systems used for power distribution, control, metering, and cable connection. They typically consist of high-voltage and low-voltage switchgear, which are used to handle the distribution and management of power at different voltage levels. High-voltage and low-voltage switchgear are indispensable equipment in power systems. They are mainly used to introduce power from the high-voltage side, step it down through transformers, and then distribute it to various electrical devices through low-voltage switchgear. They integrate protective devices such as switches, circuit breakers, and fuses, as well as control elements such as buttons, indicator lights, and meters, forming a complete power distribution device.

[0003] Chinese Utility Model Patent Publication No. CN219918143U discloses a high-voltage distribution cabinet with anti-interference function. This high-voltage distribution cabinet with anti-interference function has an air inlet. When air enters the cabinet through the air inlet, the air volume increases and the pressure decreases after flowing into the cabinet through the large and small holes, thus lowering the temperature and achieving better cooling. However, this high-voltage distribution cabinet with anti-interference function only relies on the cooperation of the fan and the air inlet to dissipate heat from the motor, resulting in poor heat dissipation performance. In addition, it does not have an installation structure for electronic components, making it inconvenient to maintain after long-term use. Its practicality is poor and it is not convenient to promote its use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an anti-interference high and low voltage distribution cabinet, which can effectively solve the problems of existing technology that only relies on the cooperation of fans and air vents to dissipate heat from motors, resulting in poor heat dissipation performance, lack of electronic component installation structure, inconvenience for maintenance after long-term use, poor practicality, and difficulty in promotion and use.

[0005] The technical solution adopted by this utility model is: an anti-interference high and low voltage distribution cabinet, including a cabinet body, a first cabinet door, and a second cabinet door.

A mounting frame is provided on the outer side of the second fixing frame. A guide block is fixedly installed on the side of the mounting frame close to the second fixing frame. Electronic components are fixedly installed on the side of the mounting frame away from the second fixing frame. Heat dissipation fins are fixedly installed on the side of the second partition near the second cabinet door. A ventilation opening is opened on the outer side of the cabinet body. A heat dissipation component is provided inside the top shell.

[0006] Preferably, the anti-interference component includes a support member, a slot, a support plate, a plug rod, a fixing block, a positioning groove, a sliding groove, a limiting block, a filter, a positioning block, and a limiting groove. The support member has a slot on its outer side. The fixing frame has a support plate inside. The bottom end of the support plate is fixedly installed with a plug rod. The top end of the support plate is fixedly installed with a fixing block. The side of the fixing block away from the support plate has a positioning groove and a sliding groove. The sliding groove is slidably connected to a limiting block. The side of the support plate away from the support member has a filter. The outer side of the filter is fixedly installed with a positioning block. The outer side of the positioning block has a limiting groove. The plug rod and the slot are plugged in. The center lines of the support plate and the fixing frame are on the same vertical line.

[0007] With the above technical solution, workers can quickly install the support plate by inserting the plug into the slot, and it is easy to maintain after long-term use.

[0008] Preferably, the positioning block and the positioning groove are plugged in, and the cross-section of the positioning block has an "L" shape.

[0009] Using the above technical solution, workers can quickly position the filter by inserting the positioning block into the positioning slot.

[0010] Preferably, the sliding groove communicates with the limiting groove, and the limiting block is adapted to the limiting groove.

[0011] With the above technical solution, after the filter is quickly positioned, the staff slides the limiting block into the limiting groove, which can realize the rapid limiting of the filter. After long-term use, it is convenient to maintain it. Through the design of the filter, it is easy to filter out electromagnetic interference and noise in the power supply, protect the equipment from voltage fluctuations and current surges, and improve the overall stability and reliability, with high anti-interference ability.

[0012] Preferably, the guide block and the guide groove are plugged in, the cross-section of the guide block is U-shaped, and multiple identical guide grooves are provided, with the multiple guide grooves distributed at equal intervals.

[0013] With the above technical solution, the staff can quickly install the mounting bracket by inserting the guide block into the guide groove, thereby enabling the rapid installation of electronic components. After long-term use, it is convenient to inspect and maintain the components.

[0017] With the above technical solution, the staff starts the water pump, which draws water from the tank through water pipe one, then drains it through water pipe two to water pipe three to dissipate heat from the electronic components, and then returns it to the tank through water pipe four. The "snake-shaped" cross-section of water pipe three increases the contact area and improves the overall heat dissipation effect, preventing the electronic components from working in a high-temperature environment for a long time, which could lead to damage and affect the normal use of the whole system. It is highly practical.

[0029] 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.

[0030] Example 1: As Figure 1-7As shown, the present invention provides an anti-interference high and low voltage distribution cabinet, including a cabinet body 1, a first cabinet door 2, and a second cabinet door 3. A top shell 4 is fixedly installed on the top of the cabinet body 1. A first fixing frame 5, a first partition 6, a second fixing frame 7, and a second partition 8 are fixedly installed inside the cabinet body 1. An anti-interference component 9 is provided inside the first fixing frame 5. A guide groove 10 is opened on the outside of the second fixing frame 7. A mounting frame 11 is provided on the outside of the second fixing frame 7. A guide block 12 is fixedly installed on the side of the mounting frame 11 close to the second fixing frame 7. Electronic components 13 are fixedly installed on the side of the mounting frame 11 away from the second fixing frame 7. A heat dissipation fin 14 is fixedly installed on the side of the second partition 8 close to the second cabinet door 3. A ventilation opening 15 is opened on the outside of the cabinet body 1. A heat dissipation component 16 is provided inside the top shell 4.

[0031] Specifically, the anti-interference component 9 includes a support member 901, a slot 902, a support plate 903, a plug rod 904, a fixing block 905, a positioning groove 906, a sliding groove 907, a limiting block 908, a filter 909, a positioning block 910, and a limiting groove 911. The support member 901 has a slot 902 on its outer side. The fixing bracket 5 has a support plate 903 inside. The plug rod 904 is fixedly installed at the bottom of the support plate 903, and the fixing block 905 is fixedly installed at the top of the support plate 903. The side of the fixing block 905 away from the support plate 903 has a positioning groove 906 and a sliding groove 907. A limiting block 908 is slidably connected inside the sliding groove 907. A filter 909 is provided on the side of the support plate 903 away from the support member 901. A positioning block 910 is fixedly installed on the outside of the filter 909. A limiting groove 911 is provided on the outside of the positioning block 910. The insertion rod 904 is inserted into the slot 902. The center lines of the support plate 903 and the fixing frame 5 are on the same vertical line. The advantage is that the operator can quickly install the support plate 903 by inserting the insertion rod 904 into the slot 902.

[0032] Specifically, the positioning block 910 and the positioning groove 906 are plug-in installed, and the cross-section of the positioning block 910 has an "L" shape. The advantage is that the operator can quickly position the filter 909 by inserting the positioning block 910 into the positioning groove 906.

[0033] Specifically, the slide 907 communicates with the limiting groove 911, and the limiting block 908 is adapted to the limiting groove 911. The advantage is that after the filter 909 is quickly positioned, the operator can slide the limiting block 908 into the limiting groove 911, achieving rapid limiting of the filter 909. This facilitates maintenance after prolonged use. The design of the filter 909 facilitates the filtering of electromagnetic interference and noise in the power supply, protecting the equipment from voltage fluctuations and current surges, while simultaneously improving overall stability and reliability, and exhibiting high anti-interference capability.

[0034] Example 2:

[0035] like Figure 2-7 As shown, as an improvement on the previous embodiment, to further facilitate heat dissipation of the electronic component 13, specifically, the heat dissipation fins 14 are adapted to the ventilation openings 15, and multiple identical heat dissipation fins 14 are provided, with the multiple heat dissipation fins 14 distributed at equal intervals. The advantage is that, through the cooperation of the heat dissipation fins 14 and the ventilation openings 15, cool air is blown through the ventilation openings 15 to the surface of the heat dissipation fins 14, carrying away the heat from the surface of the heat dissipation fins 14, thus achieving rapid heat dissipation of the electronic component 13.

[0036] Specifically, the heat dissipation assembly 16 includes a water pump 1601, a water tank 1602, a first water pipe 1603, a second water pipe 1604, a third water pipe 1605, and a fourth water pipe 1606. The water pump 1601 and the water tank 1602 are fixedly installed inside the top shell 4. The first water pipe 1603 is arranged between the water pump 1601 and the water tank 1602. The second water pipe 1604 is arranged on the outside of the water pump 1601. The third water pipe 1605 is arranged on the outside of the partition plate 2 8. The fourth water pipe 1606 is arranged on the outside of the water tank 1602. The first water pipe 1603, the second water pipe 1604, the third water pipe 1605, and the fourth water pipe 1606 are connected. The cross-section of the third water pipe 1605 is a "snake-shaped" structure. The advantages are that when the operator starts the water pump 1601, the water pump 1601 draws water out of the water tank 1602 through the first water pipe 1603, and then discharges it into the inside of the third water pipe 1605 through the second water pipe 1604 to dissipate heat from the electronic component 13. Then, it flows back into the water tank 1602 through the fourth water pipe 1606. The "snake-shaped" cross-section design of the third water pipe 1605 increases the contact area and improves the overall heat dissipation effect, preventing the electronic component 13 from working in a high-temperature environment for a long time, which could lead to damage and affect the normal use of the whole system. It is highly practical.

[0037] Specifically, the guide block 12 and the guide groove 10 are plug-in installed. The cross-section of the guide block 12 is U-shaped, and multiple identical guide grooves 10 are provided, distributed at equal intervals. The advantage is that workers can quickly install the mounting bracket 11 by inserting the guide block 12 into the guide groove 10, thereby enabling the rapid installation of electronic components 13. After prolonged use, it facilitates maintenance. The design of multiple guide grooves 10 allows for adjustment of the distance between adjacent mounting brackets 11, facilitating the installation of electronic components 13 of different sizes, and providing high adaptability.

[0038] Working principle: During installation, the operator inserts the plug 904 into the slot 902 to quickly install the support plate 903. Then, the operator inserts the positioning block 910 into the positioning groove 906 to quickly position the filter 909. After quickly positioning the filter 909, the operator slides the limiting block 908 into the limiting groove 911 to quickly limit the filter 909, facilitating maintenance after prolonged use. Next, the operator inserts the guide block 12 into the guide groove 10 to quickly install the mounting bracket 11. The design of multiple guide grooves 10 facilitates adjustment of the distance between adjacent mounting brackets 11, making it easy to install electronic components 13 of different sizes, with high adaptability. During use, the operator starts the water pump 1601, which draws water from the water tank 1602 through the water pipe 1603. The water flows out through water pipe 1604 and then into water pipe 1605 to dissipate heat from electronic component 13. It then flows back into water tank 1602 through water pipe 1606. The "serpentine" cross-section of water pipe 1605 increases the contact area and improves the overall heat dissipation effect, preventing electronic component 13 from operating in a high-temperature environment for extended periods, thus avoiding damage and ensuring normal operation. This design is highly practical. Through the cooperation of heat dissipation fins 14 and vents 15, cool air is blown onto the surface of heat dissipation fins 14 through vents 15, carrying away heat and achieving rapid heat dissipation for electronic component 13. The filter 909 facilitates the filtering of electromagnetic interference and noise from the power supply, protecting the equipment from voltage fluctuations and current surges, while also improving overall stability and reliability, and exhibiting high anti-interference capability.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
