Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet devices, and in particular to a high and low voltage power distribution cabinet for circuit distribution. Background Art

[0002] High and low voltage distribution cabinets are core equipment in the power system for receiving, distributing, controlling, protecting and monitoring electric energy. High voltage distribution cabinets and low voltage distribution cabinets receive electric energy in different ways. High voltage distribution cabinets receive high voltage electric energy from the power grid or generator, while low voltage distribution cabinets receive low voltage electric energy from the secondary side of the transformer.

[0003] Existing high and low voltage distribution cabinets achieve the effects of dust prevention, dust reduction, waterproofing and fire extinguishing by setting up a closed structure to isolate the inside of the distribution cabinet from the external environment. However, the heat dissipation effect in the distribution cabinet is affected after the closed structure is set up. Moreover, since some distribution cabinets need to be placed side by side in multiple groups, the heat dissipation effect of the distribution cabinet will be further reduced, resulting in heat accumulation between the two connected distribution cabinets, causing accelerated aging of electrical components and increased failure rate. At the same time, the existing distribution cabinet is equipped with fixed wire troughs and metal clips for fixing electrical components, which makes it difficult to expand the distribution cabinet in the future. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art that the heat dissipation effect in the distribution cabinet is affected and the expansion of the distribution cabinet is difficult after the closed structure is set, and to propose a high and low voltage distribution cabinet for circuit distribution.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The conduction assembly includes a heat insulating plate and a heat conducting plate plugged into the inner wall of the main frame, wherein the closed portion of the heat insulating plate and the heat conducting plate forms an air conducting cavity, and the air conducting cavity is connected to the open slot;

[0008] The clamping assembly includes an assembly platform fixed to the surface of the heat conducting plate, a clamping platform is plugged into the side of the assembly platform, and the clamping platform and the heat conducting plate are connected to a plug valve via a connecting assembly;

[0009] The partition assembly comprises a partition plate plugged into the inner wall of the opening slot, and a conducting cavity communicating with the opening slot is provided inside the partition plate.

[0010] Preferably, an assembly platform is fixed on the surface of the partition plate, and the assembly platform is used to increase the number of clamping platforms.

[0011] Preferably, the refrigeration assembly includes a limiting hole opened on the top of the main frame, the inner wall of the limiting hole is plugged with a refrigerator body, the top of the refrigerator body is sleeved with a dust cover, and the bottom of the dust cover is fixed to the upper surface of the main frame.

[0012] Preferably, the door frame assembly includes a closing door connected to the surface of the main frame through a hinge, and a sealing strip is provided at the joint between the closing door and the main frame.

[0013] Preferably, the conductive component includes a copper busbar inserted into one side of the partition plate, and a plurality of mounting grooves are provided on the surface of the copper busbar.

[0014] Preferably, the circulation component includes connecting holes opened at the bottom of the main frame and the surface of the partition plate, a motor fixing frame is fixed to the bottom of the main frame, a driving motor is fixed to the inner wall of the motor fixing frame, the output end of the driving motor is plugged into the inner wall of the connecting hole, the driving motor is located on the side of the conduction cavity and the gas circulation cavity and is fixed with gas circulation fan blades, and the output end of the driving motor located inside the main frame is fixed with airflow stirring blades.

[0015] Preferably, the connecting component includes a through hole opened on the surface of the heat conduction plate and a boosting hole opened in the middle of the clamping platform. The two ends of the plug valve are respectively inserted into the inner walls of the through hole and the boosting hole, and the connection between the end of the plug valve and the boosting hole constitutes a boosting chamber.

[0016] Preferably, isolation plates are provided inside the upper and lower ends of the gas circulation chamber and in the middle of the two ends of the conduction chamber, so that the isolation plates are used to separate the gas circulation chamber and the conduction chamber.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides an isolation plate in the gas circulation chamber and the conduction chamber, which can cooperate with the rotation of the gas circulation fan blades to form two groups of air flows flowing in opposite directions in the conduction chamber. The two groups of air flows can promote the formation of two groups of circulating air flows flowing in opposite directions in the gas circulation chamber. The air guide chamber can form a vortex through the open groove between the two groups of circulating air flows, effectively improving the heat dissipation and heat exchange efficiency of various parts of the distribution cabinet, avoiding heat accumulation in various parts of the distribution cabinet, and at the same time, it is used in conjunction with the clamping table clamped on the assembly table on the surface of the heat conduction plate to cool the electrical components. When the power of the electrical components is too high or short-circuited to generate high temperature, causing the clamping table to heat up, the gas in the boosting chamber at one end of the plug valve expands due to the heat, and the plug valve moves to connect the air guide chamber with the boosting hole, so that the low-temperature flame-retardant gas in the gas circulation chamber is quickly discharged into the distribution cabinet, quickly reducing the oxygen content and temperature around the high-temperature electrical components to achieve a flame retardant and cooling effect, and at the same time, it can also prevent electric sparks from igniting other flammable materials.

[0019] 2. The present invention changes the existing technology of using guide rails as a fixed structure for electrical components through the coordinated setting of the assembly table and the clamping table. By fixing the electrical components on the inner wall of the distribution cabinet, the heat dissipation of the electrical components is facilitated, and heat accumulation caused by poor gas flow between the electrical components is avoided. The capacity can be easily expanded by adding electrical components on the partition plate in the later stage. The groove formed by the combination of the assembly table and the clamping table can be used as a wire trough, which is convenient for routing or placing copper bars and facilitating the later arrangement of wires for inspection and maintenance. Similarly, the assembly table on the partition plate facilitates the later expansion of the electrical components in the distribution cabinet, and the expansion can be carried out without moving or replacing the original electrical components. Position or model.

[0020] 3. The present invention adopts the arrangement of heat insulation panels. Firstly, it can avoid heat accumulation on both sides of the distribution cabinets when they are placed in the same row, which affects the heat dissipation efficiency of the distribution cabinets. Secondly, when multiple distribution cabinets are placed in the same row, the heat insulation panels can be removed to form a larger gas circulation chamber, so that the heat dissipation efficiency of each distribution cabinet can complement each other, thus avoiding the high-power operation of a certain refrigerator body and reducing power consumption. Moreover, when one of the distribution cabinets fails and loses power, other distribution cabinets can assist in cooling and extinguishing the fire, effectively reducing the fire rate caused by device failure.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0034] Example, see Figures 1 to 9 A high and low voltage distribution cabinet for circuit distribution includes a main frame 1, a gas circulation chamber 2 is provided inside the main frame 1, a refrigeration component is provided on the top of the main frame 1, and further, the refrigeration component includes a limiting hole 12 opened on the top of the main frame 1, a refrigerator body 13 is inserted into the inner wall of the limiting hole 12, a dust cover 14 is sleeved on the top of the refrigerator body 13, and the bottom of the dust cover 14 is fixed to the upper surface of the main frame 1.

[0035] A further advantage of adopting the above method is that the refrigeration plate of the refrigerator body 13 is inserted into the gas circulation chamber 2 from the limiting hole 12 opened at the top of the main frame 1, cooling the gas in the gas circulation chamber 2 and the conduction chamber 11 in the partition plate 10, thereby ensuring that the temperature inside the entire distribution cabinet is in a standard state, preventing the electrical components in the distribution cabinet from being reduced in efficiency or accelerated aging due to high temperature, or even high temperature fire.

[0036] Three groups of conduction components are provided on the surrounding side of the main frame 1. Furthermore, the conduction components include a heat insulation plate 4 and a heat conduction plate 5 inserted into the inner wall of the main frame 1. The closed part of the heat insulation plate 4 and the heat conduction plate 5 constitutes an air guide cavity 6, which is connected to the opening groove 3.

[0037] A further advantage of adopting the above method is that the air guide cavity 6 can allow the low-temperature gas in the gas circulation cavity 2 to enter, thereby reducing the temperature of the electrical components on the clamping table 8 connected to the assembly table 7. The heat insulation board 4 can be disassembled as needed. When multiple distribution cabinets are placed side by side for use, the heat insulation board 4 can be removed to connect the air guide cavities 6 on multiple distribution cabinets. When a fire occurs in a distribution cabinet and the power is cut off, other distribution cabinets can be used to assist in cooling and extinguishing the fire.

[0038] and a set of door frame assemblies, further, the door frame assembly includes a closing door 15 connected to the surface of the main frame 1 by a hinge, and a sealing strip is provided at the joint between the closing door 15 and the main frame 1;

[0039] The further benefit of adopting the above method is that the sealing strip can insulate and reduce noise and reduce dust ingress, preventing dust accumulation on the surface of electrical components from affecting heat dissipation. At the same time, a circular hole is opened on the sealing strip, which is used to balance the air pressure of the distribution cabinet and the external environment, avoiding imbalance of internal and external pressure of the distribution cabinet.

[0040] A clamping assembly is provided on the surface of the conduction assembly. Further, the clamping assembly includes an assembly platform 7 fixed to the surface of the heat conducting plate 5 , and a clamping platform 8 is inserted into the side of the assembly platform 7 .

[0041] Further advantages of adopting the above method are: a number of grooves are provided at the contact end of the clamping platform 8 and the heat conducting plate 5, one of which is used to improve the cooling and heat dissipation efficiency of the clamping platform 8, and the other is that after the clamping platform 8 is heated and the temperature exceeds the threshold value, the plug valve 9 moves, and the gas circulation chamber 2 is connected with the boost hole 23, and the low-temperature flame-retardant gas flow can quickly flow into the boost hole 23 through the gas guide chamber 6, and then flow out from the groove of the clamping platform 8, cooling and flame-retarding high-temperature electrical appliances or electrical appliances that have caught fire. The movement of the plug valve 9 is affected by the temperature of the clamping platform 8. When the electrical appliances on the clamping platform 8 are short-circuited or operate at more than the maximum power, the temperature of the electrical appliances will rise rapidly, thereby causing the temperature on the clamping platform 8 to rise rapidly. At this time, the gas in the boost chamber at one end of the boost hole 23 expands due to the heat, driving the plug valve 9 to move, so that the through hole 22 is connected with the gas guide chamber 6, facilitating the flow of low-temperature flame-retardant gas in the gas guide chamber 6.

[0042] It is worth noting that the low-temperature flame-retardant gas in each chamber on the main frame 1 has a certain pressure, the purpose of which is to facilitate the low-temperature flame-retardant gas to enter the distribution cabinet through the boost hole 23 to cool down the electrical components and retard them.

[0043] The clamping table 8 and the heat conducting plate 5 are connected with a plug valve 9 through a connecting component. Furthermore, the connecting component includes a through hole 22 opened on the surface of the heat conducting plate 5 and a boosting hole 23 opened in the middle of the clamping table 8. The two ends of the plug valve 9 are respectively inserted into the inner walls of the through hole 22 and the boosting hole 23. The connection between the end of the plug valve 9 and the boosting hole 23 constitutes a boosting chamber.

[0044] A further advantage of adopting the above method is that an inclined surface is provided on one end side of the plug valve 9 inserted into the through hole 22. When the plug valve 9 moves, the air guide cavity 6 can be connected with the through hole 22. The boosting cavity on the boosting hole 23 is affected by the temperature of the clamping table 8. When the clamping table 8 is at a high temperature, the gas in the boosting cavity can be expanded to drive the plug valve 9 to move.

[0045] It is worth noting that: the boost hole 23 is a blind hole, and the cavity at the connection between the blind hole end of the boost hole 23 and the plug valve 9 is the boost cavity. The gas in the boost cavity is affected by the heat transferred to the clamping table 8 by the electrical components. After the temperature of the clamping table 8 reaches the gas expansion value in the boost cavity, it can drive the plug valve 9 to move to the end away from the boost hole 23. When the inclined surface at one end of the plug valve 9 slides out from the inner wall of the through hole 22, the low-temperature flame-retardant gas in the gas guide cavity 6 flows into the boost hole 23 through the through hole 22. Since the boost hole 23 and the sink groove opened at one end of the clamping table 8 have overlapping parts, the low-temperature flame-retardant gas flowing into the boost hole 23 will flow out from the overlapping place of the sink groove.

[0046] An open groove 3 connected to the gas circulation chamber 2 is opened in the middle of the main frame 1, and a partition component is provided inside the open groove 3. Furthermore, the partition component includes a partition plate 10 inserted into the inner wall of the open groove 3, and a conduction cavity 11 connected to the open groove 3 is opened inside the partition plate 10. An assembly table 7 is fixed on the surface of the partition plate 10, and the assembly table 7 is used to increase the number of clamping tables 8. Isolation plates are provided in the interior of the upper and lower ends of the gas circulation chamber 2 and in the middle of the two ends of the conduction cavity 11, so that the isolation plates are used to separate the chambers of the gas circulation chamber 2 and the conduction cavity 11.

[0047] Further advantages of adopting the above method are: the conduction chamber 11 is used to connect the gas circulation chamber 2 to ensure that the temperature in the entire distribution cabinet is within the operating temperature range, the clamping table 8 can be placed according to needs, and the groove formed by the assembly table 7 and the clamping table 8 can facilitate the routing of copper bars or wires, making the line routing clear and convenient for subsequent maintenance or replacement of wires. The notch on the side of the heat conducting plate 5 is inserted into the open groove 3 for fixation and connecting the gas conduction chamber 6 with the gas circulation chamber 2.

[0048] It is worth noting that: the isolation plate arranged inside the gas circulation chamber 2 and the conduction chamber 11, the top of the gas circulation chamber 2 is divided into two chambers with the center plane of the refrigerator body 13 as the dividing plane, the chamber at the bottom of the gas circulation chamber 2 and the chamber of the conduction chamber 11 are symmetrical with the driving motor 19 as the center plane, and the isolation plate can separate the gas circulation chamber 2 and the conduction chamber 11 into two chambers. Therefore, when the gas circulation fan 20 rotates in the conduction chamber 11, the two chambers of the conduction chamber 11 separated by the isolation plate will form two unidirectional airflows with opposite airflow directions. Driven by the unidirectional airflow, two groups of circulating airflows with opposite flow directions will be formed in the gas circulation chamber 2 with the isolation plate as the center plane of symmetry. The two groups of circulating airflows are cooled after flowing through the refrigerator body 13. Under the action of the two groups of circulating airflows, the heat dissipation of the device and the heat exchange efficiency of each position can be effectively improved to avoid the occurrence of heat accumulation.

[0049] A conductive component is provided at one end of the partition assembly close to the interior of the main frame 1 . Furthermore, the conductive component includes a copper busbar 16 plugged into one side of the partition plate 10 , and a plurality of mounting grooves are provided on the surface of the copper busbar 16 .

[0050] A further advantage of adopting the above method is that the copper busbar 16 is used as a bus for positive, negative and ground wires, and the mounting slots on the copper busbar 16 are convenient for subsequent expansion of the number of electrical components.

[0051] The main frame 1 and the partition assembly are connected through a circulation assembly. Furthermore, the circulation assembly includes a connection hole 17 opened on the bottom of the main frame 1 and the surface of the partition plate 10. A motor fixing frame 18 is fixed to the bottom of the main frame 1. A drive motor 19 is fixed to the inner wall of the motor fixing frame 18. The output end of the drive motor 19 is plugged into the inner wall of the connection hole 17. The drive motor 19 is located on the side of the conduction cavity 11 and the gas circulation cavity 2. A gas circulation fan blade 20 is fixed to the side of the drive motor 19 located inside the main frame 1. An air flow stirring blade 21 is fixed to the outside of the output end of the drive motor 19 located inside the main frame 1.

[0052] The further benefit of adopting the above method is that the air flow stirring blades 21 can make the gas in the distribution cabinet flow, avoiding high temperature of some electrical components, and the rotation of the gas circulation fan blades 20 can drive the gas flow in the conduction cavity 11, and the gas circulation flow in the gas circulation cavity 2 will cool the distribution cabinet.

[0053] When the present invention is in use, the gas in the gas circulation chamber 2 of the main frame 1 is cooled by the refrigerator body 13, and the gas circulation fan blades 20 and the air flow stirring blades 21 are driven to rotate by the output end of the drive motor 19. The gas circulation fan blades 20 circulate the gas in the gas circulation chamber 2, the conduction chamber 11 and the gas guide chamber 6, and the air flow stirring blades 21 circulate the gas in the power distribution cabinet.

[0054] When the distribution cabinets are placed side by side, the heat insulation plate 4 can be removed to connect the gas guide chambers 6 on the adjacent distribution cabinets. When a certain distribution cabinet is working at high power, multiple distribution cabinets can be used to provide complementary cooling, thereby reducing energy consumption. At the same time, when a distribution cabinet loses power and a fire occurs, since the gas circulation chambers 2 of the two distribution cabinets can be connected through the gas guide chamber 6, the adjacent distribution cabinet can be used for cooling and fire extinguishing.

[0055] When the electrical components on the clamping platform 8 are short-circuited or operate at a power exceeding the maximum rated power, in order to prevent high-temperature fires, the plug valve 9 located in the supercharging hole 23 moves due to heat, connecting the air guide cavity 6 with the supercharging hole 23 through the through hole 22. At this time, the low-temperature flame-retardant gas in the air guide cavity 6 can flow out from the clamping platform 8, reducing the oxygen content and temperature around the electrical components at the corresponding position, thereby preventing the electrical components from catching fire due to high temperature.

[0056] After the clamping platform 8 is clamped onto the assembly platform 7, a wire trough can be formed at the intersection of the clamping platform 8 and the assembly platform 7, which is convenient for finding the wire source and solves the problem of using wire troughs to fix wires in the prior art, which is inconvenient for later sorting of the wires. At the same time, the clamping platform 8 is fixed on the heat conducting plate 5 to fix the electrical components, and the side of the distribution cabinet is used to fix the electrical components first, which can reserve more space for the convenience of later expansion of electrical components. At the same time, the method of fixing the electrical components on the side can increase the heat dissipation efficiency and prevent heat accumulation, and can accurately determine the fire and high temperature points, and directionally cool down and extinguish the fire, which greatly improves the safety of the device. It can also realize the connection of multiple distribution cabinets through the air guide cavity 6, solving the problem that some distribution cabinets have sufficient heat dissipation effect, resulting in increased power consumption. It can also cooperate with multiple distribution cabinets to solve the problem in the prior art that a distribution cabinet cannot be extinguished in time when it is on fire and the power is cut off.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
