Description

Technical Field

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

[0002] High and low voltage power distribution cabinets are core devices in the power system for receiving, distributing, controlling, protecting, and monitoring electric energy. The high voltage power distribution cabinet and the low voltage power distribution cabinet receive electric energy through different channels. The high voltage power distribution cabinet receives high voltage electric energy from the power grid or a generator, and the low voltage power distribution cabinet receives low voltage electric energy from the secondary side of a transformer.

[0003] The existing high and low voltage power distribution cabinets isolate the interior of the power distribution cabinet from the external environment by setting a sealed structure to achieve the effects of dust and dust reduction, waterproofing, and fire extinguishing. However, after the sealed structure is set, the heat dissipation effect inside the power distribution cabinet is affected, and since some power distribution cabinets need to be placed side by side in multiple groups, the heat dissipation effect of the power distribution cabinet will be further reduced, resulting in heat accumulation between two adjacent power distribution cabinets, causing the electrical components to age rapidly and the failure rate to increase. At the same time, the existing power distribution cabinet is internally provided with a fixed wire groove and a metal card board for fixing electrical components, making it difficult to expand the power distribution cabinet later. Summary of the Invention

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

Three conduction components and one door frame component are provided on the periphery of the main body frame. A clamping component is provided on the surface of the conduction component. An opening groove communicating with the gas circulation chamber is formed in the middle of the main body frame. A partition component is provided inside the opening groove. A conductive component is provided at one end of the partition component close to the inside of the main body frame. The main body frame and the partition component are connected by a circulation component; The conduction component includes a heat insulation plate and a heat conduction plate inserted into the inner wall of the main body frame. The closed part of the heat insulation plate and the heat conduction plate forms a gas conduction chamber, and the gas conduction chamber is communicated with the opening groove; The clamping component includes an assembly table fixed on the surface of the heat conduction plate. A clamping table is inserted on the side of the assembly table. The clamping table and the heat conduction plate are connected with a plug valve through a communication component; The partition component includes a partition plate inserted into the inner wall of the opening groove. A conduction chamber communicating with the opening groove is formed inside the partition plate.

[0006] Preferably, an assembly table is fixed on the surface of the partition board, and the assembly table is used to increase the number of clamping tables.

[0007] Preferably, the refrigeration assembly includes a limit hole opened at the top of the main frame, the inner wall of the limit hole is inserted with a main refrigeration machine, the top of the main refrigeration machine is sleeved with a dust isolation cover, and the bottom of the dust isolation cover is fixed on the upper surface of the main frame.

[0008] 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.

[0009] Preferably, the conductive assembly includes a copper busbar inserted on one side of the partition board, and a plurality of mounting grooves are opened on the surface of the copper busbar.

[0010] Preferably, the circulation assembly includes connection holes opened at the bottom of the main frame and on the surface of the partition board. A motor fixing frame is fixed at the bottom of the main frame. A driving motor is fixed inside the motor fixing frame. The output end of the driving motor is inserted into the inner wall of the connection hole. A gas circulation fan blade is fixed on the side of the driving motor located in the conduction cavity and the gas circulation cavity. An air flow stirring blade is fixed outside the output end of the driving motor located inside the main frame.

[0011] Preferably, the communication assembly includes a through hole opened on the surface of the heat conducting plate and a pressure increasing hole opened in the middle of the clamping table. The two ends of the plug valve are respectively inserted into the inner walls of the through hole and the pressure increasing hole, and a pressure increasing cavity is formed at the connection between the end of the plug valve and the pressure increasing hole.

[0012] Preferably, isolation plates are provided in the upper and lower parts of the gas circulation cavity and in the middle of both ends of the conduction cavity, and the isolation plates are used to separate the chambers of the gas circulation cavity and the conduction cavity.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting a partition board in the gas circulation cavity and the conduction cavity, the present invention can form two groups of airflows flowing in opposite directions in the conduction cavity in cooperation with the rotation of the gas circulation fan blades. Through the two groups of airflows, two groups of circulating airflows flowing in opposite directions can be promoted to form in the gas circulation cavity. The air guide cavity can form a vortex through the opening groove between the two groups of circulating airflows, effectively improving the heat dissipation and heat exchange efficiency of each part of the power distribution cabinet, avoiding heat accumulation in each part of the power distribution cabinet. At the same time, it is equipped with a clamping table clamped on the surface mounting table of the heat conducting plate to cool the electrical components. When the electrical components have too high power or short circuit to generate high temperature, resulting in the clamping table heating up, the gas in the pressurization cavity at one end of the plug valve expands due to heat, and the plug valve moves to connect the air guide cavity with the pressurization hole, so that the low-temperature flame-retardant gas in the gas circulation cavity is quickly discharged into the power distribution cabinet, quickly reducing the oxygen content and temperature around the high-temperature electrical components, playing a role of flame retardant and temperature reduction, and at the same time, it can also prevent electric sparks from igniting other flammable substances.

[0014] 2. Through the combined setting of the mounting table and the clamping table, the present invention changes the existing technology of using a guide rail as the fixed structure of electrical components. By fixing electrical components on the inner wall of the power distribution cabinet, it is convenient for the electrical components to dissipate heat, avoiding heat accumulation caused by poor gas flow between electrical components. Later, by installing electrical components on the partition board, it is convenient to expand the capacity. The groove formed by the combination of the mounting table and the clamping table can be used as a wire groove, facilitating wiring or placing copper bars, and facilitating the later arrangement of wires for detection and maintenance. Similarly, the mounting table on the partition board is convenient for later expanding the electrical components in the power distribution cabinet, and the capacity can be expanded without moving or replacing the positions or models of the original electrical components.

[0015] 3. Through the setting of the heat insulation board, first, it can avoid heat accumulation on both sides when multiple power distribution cabinets are placed side by side, affecting the heat dissipation efficiency of the power distribution cabinet. Second, when multiple power distribution cabinets are placed side by side, the heat insulation board can be disassembled to form a larger gas circulation cavity, enabling the heat dissipation efficiency of each power distribution cabinet to be complementary, avoiding a high-power operation of a certain refrigeration machine main body, reducing power consumption, and when one of the power distribution cabinets fails and loses power, other power distribution cabinets can be used to assist in cooling and extinguishing fires, effectively reducing the fire rate caused by device failures.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example, refer to Figures 1 to 9 , a high and low voltage power distribution cabinet for circuit distribution, including 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. Further, the refrigeration component includes a limiting hole 12 opened on the top of the main frame 1. The inner wall of the limiting hole 12 is inserted with a refrigeration machine main body 13. A dust-proof cover 14 is sleeved on the top of the refrigeration machine main body 13. The bottom of the dust-proof cover 14 is fixed to the upper surface of the main frame 1.

[0022] The advantage of the above further is that: the refrigeration sheet of the refrigeration machine main body 13 is inserted into the gas circulation chamber 2 from the limiting hole 12 opened at the top end of the main frame 1 to cool the gas in the gas circulation chamber 2 and the conduction chamber 11 in the partition plate 10, so as to ensure that the temperature inside the entire power distribution cabinet is in a standard state, prevent the electrical components in the power distribution cabinet from reducing efficiency or accelerating aging due to high temperature, or even catching fire due to high temperature.

[0023] Three groups of conduction components are provided on the periphery of the main frame 1. Further, the conduction component includes 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 forms a gas conduction chamber 6. The gas conduction chamber 6 is communicated with the opening groove 3.

[0024] The advantage of the above further is that: the gas conduction chamber 6 can allow the low-temperature gas in the gas circulation chamber 2 to enter, so as to reduce the temperature of the electrical components on the clamping table 8 connected to the assembly table 7. The heat insulation plate 4 can be disassembled according to needs. When multiple power distribution cabinets are placed side by side for use, the heat insulation plate 4 can be disassembled to connect the gas conduction chambers 6 on multiple power distribution cabinets. When a certain power distribution cabinet catches fire and loses power, other power distribution cabinets can be used to assist in cooling and extinguishing the fire.

[0025] And a group of door frame components. Further, the door frame component includes a closing door 15 connected to the surface of the main frame 1 through a hinge. A sealing strip is provided at the joint of the closing door 15 and the main frame 1; The advantage of the above further is that: the sealing strip plays a role in sound insulation and noise reduction and reducing the entry of dust, preventing the accumulation of dust on the surface of electrical components from affecting heat dissipation. At the same time, round holes are opened on the sealing strip, and the round holes are used to balance the air pressure between the power distribution cabinet and the external environment, avoiding the imbalance of internal and external pressure of the power distribution cabinet.

[0026] The surface of the conduction component is provided with a clamping component. Further, the clamping component includes an assembly table 7 fixed on the surface of the heat conducting plate 5, and a clamping table 8 is inserted into the side surface of the assembly table 7.

[0027] The advantages of the above are as follows: A plurality of sinking grooves are opened at the contact end of the clamping table 8 and the heat conducting plate 5. Firstly, it is used to improve the cooling and heat dissipation efficiency of the clamping table 8. Secondly, after the temperature of the clamping table 8 rises due to heat and exceeds the threshold value, the plug valve 9 moves, and after the gas circulation cavity 2 is communicated with the pressurizing hole 23, the low-temperature flame-retardant gas flow can quickly flow into the pressurizing hole 23 through the air guide cavity 6, and then flow out from the sinking grooves of the clamping table 8 to cool and retard the fire of high-temperature electrical appliances or on-fire electrical appliances. The movement of the plug valve 9 is affected by the temperature of the clamping table 8. When the electrical appliance on the clamping table 8 is short-circuited or operates beyond the maximum power, the temperature of the electrical appliance will rise rapidly, thereby causing the temperature of the clamping table 8 to rise rapidly. At this time, the gas in the pressurizing cavity at one end of the pressurizing hole 23 expands due to heat, driving the plug valve 9 to move, so that the through hole 22 is communicated with the air guide cavity 6, facilitating the low-temperature flame-retardant gas in the air guide cavity 6 to flow out.

[0028] It should be noted that: There is a certain air pressure in the low-temperature flame-retardant gas in each chamber of the main body frame 1. The purpose is to facilitate the low-temperature flame-retardant gas to enter the power distribution cabinet through the pressurizing hole 23 to cool and retard the electrical components.

[0029] The clamping table 8 and the heat conducting plate 5 are connected with a plug valve 9 through a connecting component. Further, the connecting component includes a through hole 22 opened on the surface of the heat conducting plate 5 and a pressurizing 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 pressurizing hole 23, and the connection part of the end of the plug valve 9 and the pressurizing hole 23 forms a pressurizing cavity.

[0030] The advantages of the above are as follows: One end side of the plug valve 9 inserted into the through hole 22 is provided with an inclined surface. When the plug valve 9 moves, the air guide cavity 6 can be communicated with the through hole 22. The pressurizing cavity on the pressurizing 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 pressurizing cavity can be promoted to expand and drive the plug valve 9 to move.

[0031] It should be noted that: The pressurizing hole 23 is a blind hole, and the cavity at the blind hole end of the pressurizing hole 23 connected to the plug valve 9 is the pressurizing cavity. The gas in the pressurizing cavity is affected by the heat transferred from the electrical component to the clamping table 8. After the temperature of the clamping table 8 reaches the gas expansion value in the pressurizing cavity, it can drive the plug valve 9 to move towards the end away from the pressurizing 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 air guide cavity 6 flows into the pressurizing hole 23 through the through hole 22. Since the pressurizing hole 23 and the sinking grooves opened at one end of the clamping table 8 have overlapping parts, the low-temperature flame-retardant gas flowing into the pressurizing hole 23 will flow out from the overlapping part of the sinking grooves.

[0032] An opening groove 3 communicating with the gas circulation chamber 2 is provided in the middle of the main body frame 1. A partition component is arranged inside the opening groove 3. Further, the partition component includes a partition plate 10 inserted into the inner wall of the opening groove 3. A conduction chamber 11 communicating with the opening groove 3 is provided 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 arranged in the middle of the upper and lower ends of the gas circulation chamber 2 and the middle of the two ends of the conduction chamber 11, and the isolation plates are used to separate the chambers of the gas circulation chamber 2 and the conduction chamber 11.

[0033] The advantage of the above further arrangement is that: the conduction chamber 11 is used to communicate with the gas circulation chamber 2 to ensure that the temperature inside the entire power distribution cabinet is within the working temperature range. The clamping tables 8 can be placed according to requirements. The grooves formed by the assembly table 7 and the clamping tables 8 can facilitate the routing of copper bars or wires, making the line routing clear and convenient for subsequent maintenance or wire replacement. The notch on the side of the heat conduction plate 5 is inserted into the opening groove 3 for fixation and to connect the air guide chamber 6 with the gas circulation chamber 2.

[0034] It should be noted that: the isolation plates arranged inside the gas circulation chamber 2 and the conduction chamber 11. The top end of the gas circulation chamber 2 is divided into two chambers with the central plane of the refrigerator main body 13 as the dividing plane. The chamber at the bottom end of the gas circulation chamber 2 and the chamber of the conduction chamber 11 take the driving motor 19 as the symmetric central plane. 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, two one-way airflows with opposite air flow directions will be formed in the two chambers separated by the isolation plate in the conduction chamber 11. Driven by the one-way airflows, two sets of circulating airflows with opposite flow directions will be formed in the gas circulation chamber 2 with the isolation plate as the symmetric central plane. After the two sets of circulating airflows flow through the refrigerator main body 13, they are cooled. Under the action of the two sets of circulating airflows, the heat dissipation of the device and the heat exchange efficiency at each position can be effectively improved, and the phenomenon of heat accumulation can be avoided.

[0035] A conductive component is arranged at one end of the partition component close to the inside of the main body frame 1. Further, the conductive component includes a copper bar plate 16 inserted into one side of the partition plate 10, and a plurality of mounting grooves are provided on the surface of the copper bar plate 16.

[0036] The advantage of the above further arrangement is that: the copper bar plate 16 is used as the bus for the positive and negative electrodes and the ground wire. At the same time, the mounting grooves on the copper bar plate 16 are convenient for subsequent use when expanding the number of electrical components.

[0037] The main body frame 1 and the partition component are connected by a circulation component. Further, the circulation component includes connection holes 17 formed on the bottom of the main body frame 1 and the surface of the partition board 10. A motor fixing frame 18 is fixed to the bottom of the main body frame 1, a driving motor 19 is fixed to the inner wall of the motor fixing frame 18, the output end of the driving motor 19 is inserted into the inner wall of the connection hole 17, and a gas circulation fan blade 20 is fixed to the side of the driving motor 19 located in the conduction cavity 11 and the gas circulation cavity 2. An air flow stirring blade 21 is fixed to the outside of the output end of the driving motor 19 located inside the main body frame 1; The advantages of the above further are: the air flow stirring blade 21 can make the gas in the power distribution cabinet flow, avoiding high temperature of some electrical components. The rotation of the gas circulation fan blade 20 can drive the gas in the conduction cavity 11 to flow, and the circulating flow of the gas in the gas circulation cavity 2 will cool down the power distribution cabinet.

[0038] When the present invention is in use, the gas in the gas circulation cavity 2 of the main body frame 1 is cooled by the refrigerator main body 13. The output end of the driving motor 19 drives the gas circulation fan blade 20 and the air flow stirring blade 21 to rotate. The gas circulation fan blade 20 makes the gas in the gas circulation cavity 2, the conduction cavity 11 and the air guiding cavity 6 circulate, and the air flow stirring blade 21 makes the gas in the power distribution cabinet circulate; When the power distribution cabinets are placed side by side, the heat insulation board 4 can be removed to connect the air guiding cavities 6 on adjacent power distribution cabinets. When a certain power distribution cabinet works at high power, the cooling of multiple power distribution cabinets can be complementary to reduce the energy consumption. At the same time, when a certain power distribution cabinet is powered off and catches fire, since the gas circulation cavities 2 of the two power distribution cabinets can be connected through the air guiding cavity 6, the adjacent power distribution cabinet can be used for cooling and extinguishing the fire; When the electrical components on the clamping table 8 are short-circuited or operate beyond the maximum rated power, to prevent fire caused by high temperature, the plug valve 9 in the pressure increasing hole 23 moves due to heat, and the air guiding cavity 6 is connected to the pressure increasing hole 23 through the through hole 22. At this time, the low-temperature flame-retardant gas in the air guiding cavity 6 can flow out from the clamping table 8 to reduce the oxygen content and temperature around the electrical components at the corresponding position, preventing fire caused by high temperature of the electrical components; After the clamping table 8 is clamped to the assembly table 7, a wire groove can be formed at the intersection of the clamping table 8 and the assembly table 7, which is convenient for finding the wire source, solves the deficiency in the prior art that using a wire groove to fix wire is inconvenient for later wire arrangement. At the same time, the clamping table 8 is fixed on the heat conducting plate 5 to fix electrical components. It is preferred to fix electrical components on the side of the power distribution cabinet, which can reserve more space for later expansion of electrical components. At the same time, the way of fixing electrical components on the side can increase the heat dissipation efficiency, prevent heat accumulation, and can accurately determine the fire and high temperature points for directional cooling and fire extinguishing, greatly improving the safety of the device. Moreover, multiple power distribution cabinets can be connected through the air guide cavity 6, solving the problem of increased power consumption caused by the excessive heat dissipation effect of some power distribution cabinets. It can also cooperate with multiple power distribution cabinets to solve the drawback in the prior art that a power distribution cabinet catches fire and loses power and cannot be extinguished in time.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
