TECHNICAL FIELD

[0001] The application relates to the technical field of power distribution cabinets, in particular to an intelligent explosion-proof power distribution cabinet for a power transmission system. BACKGROUND

[0002] A high-voltage power distribution cabinet refers to an electric product with a voltage level of 3.6 kV to 550 kV, which is used for power generation, power transmission, power distribution, power conversion and consumption, and plays a role of switching, control or protection, mainly including high-voltage circuit breakers, high-voltage disconnecting switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices and high-voltage switch cabinets and the like. The high-voltage switch manufacturing industry is an important part of the power transmission equipment manufacturing industry and plays a very important role in the entire electric power industry.

[0003] The power distribution cabinet for the power transmission system usually needs to pay attention to the explosion-proof of the power distribution cabinet, and the explosion-proof of the traditional power distribution cabinet usually depends on thick-wall metal. The thick-wall metal has poor heat dissipation performance and is easy to cause heat accumulation, and the heat dissipation holes are easy to damage the explosion-proof integrity. SUMMARY

[0004] In order to solve the problem that the explosion-proof of the traditional power distribution cabinet usually depends on thick-wall metal, the thick-wall metal has poor heat dissipation performance and is easy to cause heat accumulation, and the heat dissipation holes are easy to damage the explosion-proof integrity in the prior art, the application provides an intelligent explosion-proof power distribution cabinet for a power transmission system, and the specific scheme is as follows.

[0005] An intelligent explosion-proof power distribution cabinet for a power transmission system, comprising a cabinet body, a partition plate is arranged in the cabinet body, an explosion-proof compartment is arranged on the lower side of the partition plate, and an electrical element is arranged in the explosion-proof compartment, a control compartment is arranged on the upper side of the partition plate, and a control element for controlling the electrical element is arranged in the control compartment.

[0006] An explosion-proof door is arranged at the explosion-proof compartment, the explosion-proof door is hinged to the explosion-proof compartment, a control door is arranged at the control compartment, the control door is hinged to the control compartment, and a control panel for displaying data of the electrical element and controlling the electrical element is arranged on the control door.

[0007] An explosion-proof layer and a phase change layer are arranged at the cabinet body at the explosion-proof compartment, the explosion-proof layer is arranged on the side close to the inside of the cabinet body, the phase change layer is arranged on the outside of the explosion-proof layer and is used for absorbing and releasing heat, a heat pipe is further embedded in the phase change layer, the heat pipe is used for absorbing heat, a heat dissipation layer is further arranged on the outside of the phase change layer, and a plurality of heat dissipation fins are arranged on the outside of the heat dissipation layer.

[0008] By adopting the above technical scheme, the separation design of the explosion-proof compartment and the control compartment effectively improves the rationality of the function partition of the power distribution cabinet, ensures the mutual independence of the electrical components and the control components, and improves the operation safety. The combined structure of the explosion-proof layer and the phase change layer can provide double protection when an explosion occurs. The phase change layer absorbs and releases heat, effectively alleviating the influence of temperature fluctuations on the equipment. The embedding of the heat pipe further enhances the heat conduction efficiency. The design of the heat dissipation layer and the heat dissipation fins realizes efficient external heat dissipation, ensuring that the power distribution cabinet can still operate stably under high load conditions, prolonging the service life of the equipment.

[0009] Optionally, a plurality of mounting grooves are arranged in the phase change layer, and an adjusting push rod is arranged in each mounting groove. The adjusting push rod is arranged at the joint of the explosion-proof layer. One end of the adjusting push rod is fixedly connected with the phase change layer, and the other end of the adjusting push rod is provided with an adjusting clamping jaw. The adjusting clamping jaw can abut against three sides of the explosion-proof layer. The adjusting push rod can push the adjusting clamping jaw to press the explosion-proof layer.

[0010] By adopting the above technical scheme, the mounting grooves and the adjusting push rods are arranged in the phase change layer of the explosion-proof power distribution cabinet. The adjusting push rod applies pressure to the explosion-proof layer through the adjusting clamping jaw to abut against three sides of the explosion-proof layer, thereby enhancing the sealing performance and stability of the explosion-proof layer at the joint. The pushing action of the adjusting push rod can adjust the stress state of the explosion-proof layer according to actual needs, reduce the occurrence of gaps in the joint surface of the explosion-proof layer, and further improve the explosion-proof performance.

[0011] Optionally, the adjusting clamping jaw comprises a jaw seat and a jaw body. The jaw body is arranged in a circumferential equidistant interval around the jaw seat. The jaw seat is fixedly arranged at the end of the adjusting push rod. A hinge rod is arranged between the jaw body and the jaw seat. One end of the hinge rod is hinged to the jaw body, and the other end of the hinge rod is hinged to the jaw seat. A hinge rod is also arranged between the jaw body and the adjusting push rod. One end of the hinge rod is hinged to the jaw body, and the other end of the hinge rod is hinged to the adjusting push rod.

[0012] By adopting the above technical scheme, the structure design of the adjusting clamping jaw enables the jaw body to be arranged in a circumferential equidistant interval around the jaw seat, thereby achieving uniform clamping of the explosion-proof layer. The arrangement of the hinge rod forms a flexible linkage structure between the jaw body, the jaw seat, and the adjusting push rod. When the adjusting push rod is pushed, the hinge rod can drive the jaw body to move, so that the jaw body accurately abuts against and presses the three sides of the explosion-proof layer, thereby enhancing the stability and sealing performance of the explosion-proof layer and improving the reliability of the overall structure.

[0013] Optionally, a circulating pipe is arranged in the heat dissipation layer. The circulating pipe is connected end to end. The circulating pipe is used to introduce cooling liquid. An explosion-proof pump is arranged on the circulating pipe. The explosion-proof pump is used to drive the cooling liquid in the circulating pipe to flow.

[0014] By implementing this technical solution, a circulation tube within the heat dissipation layer, which is fed with coolant, effectively absorbs heat transferred from the phase change layer, improving heat dissipation efficiency. An explosion-proof pump drives the coolant flow, ensuring even distribution throughout the circulation tube, thereby achieving comprehensive cooling of the heat dissipation layer. This design helps maintain a stable temperature within the distribution cabinet and enhances the reliability of electrical components.

[0015] Optionally, the heat dissipation fins are arranged at equal intervals along the heat dissipation layer, the heat dissipation fins are arranged in parallel, the circulation pipes are bent along the heat dissipation fins, and circulation pipes are provided between the heat dissipation fins.

[0016] By adopting this technical solution, the fins are evenly spaced and arranged in parallel along the heat dissipation layer, effectively increasing the heat dissipation area and optimizing the heat dissipation path, thereby improving heat dissipation efficiency. The circulation tubes are bent along the heat dissipation fins and distributed between them, ensuring that the coolant flows through each fin, achieving uniform heat dissipation and further improving overall heat dissipation performance.

[0017] Optionally, a protrusion is provided on the heat dissipation layer corresponding to the circulation pipe, the protrusion is protruded toward the outside of the cabinet, and the circulation pipe is embedded in the protrusion.

[0018] By adopting the above technical solution, the raised portion can effectively increase the contact area between the circulation pipe and the outside world, thereby further improving the heat dissipation effect.

[0019] Optionally, a temperature sensor is provided on the heat dissipation layer, and the temperature sensor is electrically connected to the explosion-proof pump. When the temperature sensor detects that the temperature rises, the speed of the explosion-proof pump increases; when the temperature sensor detects that the temperature drops, the speed of the explosion-proof pump decreases.

[0020] By implementing this technical solution, a temperature sensor is installed on the heat dissipation layer and electrically connected to the explosion-proof pump, enabling the pump to automatically adjust its speed based on temperature changes. When the temperature rises, the pump speed increases, accelerating the flow of coolant within the circulation pipe and improving heat dissipation efficiency. When the temperature drops, the pump speed decreases, reducing energy consumption. This achieves intelligent temperature control management and improves the stability and energy efficiency of equipment operation.

[0021] Optionally, a flow rate sensor is provided in the circulation pipe, and the flow rate sensor is electrically connected to the adjusting push rod. When the flow rate sensor detects that the flow rate is greater than a set value, the adjusting push rod pushes the adjusting claw to perform a clamping action.

[0022] Through the above technical scheme, when the flow rate of the cooling liquid in the circulating pipe is greater than the set value, the flow rate sensor can timely detect the state change, and trigger the action of the adjusting push rod through the electrical connection. The adjusting push rod pushes the adjusting clamping jaw to perform clamping action, thereby exerting additional fixing force on the explosion-proof layer and enhancing the stability of the explosion-proof layer. This design can effectively prevent the explosion-proof layer from deforming or being damaged due to pressure or vibration when the flow rate is too high due to abnormality of the cooling system, thereby improving the overall safety and reliability of the power distribution cabinet.

[0023] Optionally, the side of the explosion-proof layer close to the phase change layer is embedded with a buffer rubber strip, and the buffer rubber strip is arranged in a cross shape.

[0024] Through the above technical scheme, the buffer rubber strip is embedded at the explosion-proof layer, and the rubber strip is arranged in a cross shape, which can effectively absorb and disperse the stress generated on the explosion-proof layer by the phase change layer during thermal expansion and contraction, thereby improving the stability and service life of the explosion-proof layer, and reducing the risk of structural damage caused by stress concentration.

[0025] Optionally, the jaw body is also fixedly provided with a buffer rubber strip, and the buffer rubber strip is used to abut against the explosion-proof layer.

[0026] Through the above technical scheme, the buffer rubber strip can effectively reduce the rigid contact between the jaw body and the explosion-proof layer, avoid damage to the explosion-proof layer caused by excessive clamping force, improve the stability of clamping, and ensure that the explosion-proof layer can bear stress uniformly when being pressed, thereby improving the reliability and safety of the overall structure.

[0027] In summary, the present application has at least the following advantages:

[0028] 1. The present application solves the problem that the explosion-proof of the traditional power distribution cabinet in the prior art usually relies on thick-walled metal, which has poor heat dissipation performance and is easy to accumulate heat, and opening heat dissipation holes can easily damage the integrity of the explosion-proof. The present application sets a phase change layer and a heat dissipation layer, which can timely absorb the heat in the power distribution cabinet and dissipate the heat through the heat dissipation layer, thereby reducing the situation that the energy continues to increase due to the high temperature inside the cabinet, and ensuring the integrity of the explosion-proof.

[0029] 2. The present application also sets a circulating pipe for cooling the heat dissipation layer, sets a temperature sensor at the heat dissipation layer, and sets a flow rate sensor in the circulating pipe. The temperature of the explosion-proof layer at the heat dissipation layer is timely judged to improve the heat dissipation efficiency. However, the flow rate of the cooling liquid needs a certain time to increase to a specified value, so when the flow rate sensor detects that the adjusting push rod needs to be started, the explosion-proof layer has been in a high temperature state for a long time. At this time, the joint surface of the explosion-proof layer is adjusted, which improves the accuracy of the adjustment of the explosion-proof layer and reduces the situation that repeated adjustment affects the adjusting clamping jaw and reduces the adjustment effect.

[0040] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0041] An intelligent explosion-proof distribution cabinet for power transmission system, such as Figure 1 and Figure 2 As shown, the cabinet 1 includes a partition 11 disposed within the cabinet 1. An explosion-proof compartment 12 is disposed below the partition 11, and the explosion-proof compartment 12 is used to house electrical components. A control compartment 13 is disposed above the partition 11, and the control compartment 13 is used to house control components for controlling the electrical components. An explosion-proof door 121 is provided at the explosion-proof compartment 12, and the explosion-proof door 121 is hingedly connected to the explosion-proof compartment 12. A control door 131 is provided at the control compartment 13, and the control door 131 is hingedly connected to the control compartment 13. A control panel 132 is provided on the control door 131, and the control door 131 is hingedly connected to the control compartment 13. In a specific implementation, the explosion-proof compartment 12 and the partition 11 are both constructed of thick-walled metal for explosion protection, while the control compartment 13 is constructed of thinner metal to reduce the weight of the overall cabinet 1.

[0042] likeFigure 2 And Figure 3 As shown in the figure, the cabinet 1 at the explosion-proof bin 12 is provided with an explosion-proof layer 2 and a phase change layer 3, the explosion-proof layer 2 is arranged near the inside of the cabinet 1, and the phase change layer 3 is arranged outside the explosion-proof layer 2 and is used to absorb and release heat. The heat pipe 31 is embedded in the phase change layer 3 and is used to absorb heat. The outside of the phase change layer 3 is provided with a heat dissipation layer 4, and the outside of the heat dissipation layer 4 is provided with a plurality of heat dissipation fins 43. In specific implementation, the phase change layer 3 is a paraffin / metal foam composite phase change material, which absorbs instantaneous high temperature through latent heat. The heat pipe 31 is a heat transfer element that can quickly transfer heat to the heat source. The phase change layer 3 cooperates with the heat pipe 31 to achieve efficient directional heat conduction. During installation, the position of the heat pipe 31 can be adjusted according to the installation position of the electrical element, so as to achieve precise positioning and heat dissipation of the electrical element, thereby further improving the cooling effect.

[0043] As shown in the figure, Figure 2 And Figure 3 The phase change layer 3 is provided with a plurality of mounting grooves 32, and the mounting grooves 32 are provided with adjusting push rods 33. The adjusting push rod 33 is arranged at the joint of the explosion-proof layer 2, one end of the adjusting push rod 33 is fixedly connected with the phase change layer 3, and the other end of the adjusting push rod 33 is provided with an adjusting clamp jaw 34. The adjusting clamp jaw 34 can abut against three sides of the explosion-proof layer 2, and the adjusting push rod 33 can push the adjusting clamp jaw 34 to press the explosion-proof layer 2. In specific implementation, the adjusting push rod 33 is an industrial-grade high-power electric push rod, which can effectively compress the joint surface of the explosion-proof layer 2. Compared with air cylinders and oil cylinders, it is safer and reduces the risk of explosion caused by gaps in the joint surface of the explosion-proof layer 2 due to high temperature deformation, thereby further improving the explosion-proof effect.

[0044] As shown in the figure, Figure 4 The adjusting clamp jaw 34 includes a jaw seat 342 and a jaw body 341. The jaw body 341 is circumferentially equidistantly spaced around the jaw seat 342. The jaw seat 342 is fixedly arranged at the end of the adjusting push rod 33. A hinge rod 343 is arranged between the jaw body 341 and the jaw seat 342. One end of the hinge rod 343 is hingedly connected with the jaw body 341, and the other end of the hinge rod 343 is hingedly connected with the jaw seat 342. A hinge rod 343 is also arranged between the jaw body 341 and the adjusting push rod 33. One end of the hinge rod 343 is hingedly connected with the jaw body 341, and the other end of the hinge rod 343 is hingedly connected with the adjusting push rod 33. In specific implementation, when the adjusting push rod 33 is pushed, the jaw body 341 can be rotated, thereby driving the jaw body 341 to adjust the joint surface from three directions, thereby further improving the explosion-proof effect.

[0045] As shown in the figure, Figure 2 And Figure 3As shown, a circulation pipe 41 is provided in the heat dissipation layer 4. The circulation pipes 41 are connected end to end. Coolant is passed through the circulation pipe 41. An explosion-proof pump 42 is provided on the circulation pipe 41 to drive the coolant flow in the circulation pipe 41. In a specific implementation, the coolant in the circulation pipe 41 is water or other medium with a high specific heat capacity, and absorbs and releases heat through continuous flow.

[0046] like Figure 1 and Figure 2 As shown, the heat dissipation fins 43 are arranged at equal intervals along the heat dissipation layer 4, with each heat dissipation fin 43 arranged in parallel. The circulation tube 41 is bent along the heat dissipation fins 43, and the circulation tube 41 is provided between the heat dissipation fins 43. The heat dissipation layer 4 is provided with a protrusion 44 corresponding to the circulation tube 41. The protrusion 44 is arranged toward the outside of the cabinet 1, and the circulation tube 41 is embedded in the protrusion 44. In specific implementation, when the coolant flows between the heat dissipation fins 43, it can effectively come into contact with the wind blowing from the outside through the protrusion 44, thereby improving the heat dissipation effect to a certain extent. The heat dissipation fins 43 can also effectively improve the heat dissipation effect of the heat dissipation layer 4 itself.

[0047] like Figure 1 and Figure 3 As shown, a temperature sensor 45 is provided on the heat dissipation layer 4 and is electrically connected to the explosion-proof pump 42. When the temperature sensor 45 detects an increase in temperature, the speed of the explosion-proof pump 42 increases. When the temperature sensor 45 detects a decrease in temperature, the speed of the explosion-proof pump 42 decreases. A flow rate sensor 46 is provided in the circulation pipe 41 and is electrically connected to the adjustment push rod 33. When the flow rate sensor 46 detects that the flow rate is greater than a set value, the adjustment push rod 33 pushes the adjustment jaw 34 to clamp. During specific implementation, when the temperature increases, the speed of the explosion-proof pump 42 increases, thereby increasing the flow rate of the coolant, increasing the heat exchange frequency of the coolant, and thus improving the heat dissipation effect. When the temperature continues to rise, it is necessary to pay attention to whether the explosion-proof layer 2 is deformed. If the coolant has a high flow rate, it means that the high temperature has been maintained for a period of time. At this time, the adjustment push rod 33 is started to press the explosion-proof layer 2, which can not only adjust the joint surface of the explosion-proof layer 2 in time, but also further improve the explosion-proof effect when an explosion occurs. Since the temperature sensor 45 is installed on the heat dissipation layer 4, it can effectively detect the temperature change and quickly dissipate heat. The flow rate sensor 46 is used to judge whether the explosion-proof layer 2 needs to be adjusted. If the temperature is within the controllable range, the coolant can control the temperature during the rising flow rate. At this time, there is no need to start the adjustment push rod 33 to push. Only in the uncontrollable state where the heat cannot be dissipated for a long time, the flow rate will continue to increase and trigger the flow rate sensor 46, reducing the situation where the adjustment push rod 33 repeatedly moves due to misjudgment of the adjustment condition and affects the adjustment effect.

[0048] like Figure 5As shown, the explosion-proof layer 2 is embedded with a buffer rubber strip 21 near one side of the phase change layer 3, and the buffer rubber strip 21 is arranged in a cross shape. In specific implementation, the buffer rubber strip 21 can provide multiple protection for the explosion-proof layer 2 when an explosion actually occurs, and further improve the explosion-proof effect.

[0049] As shown in the figure, Figure 4 As shown, the claw body 341 is also fixedly provided with a buffer rubber strip 21 for abutting against the explosion-proof layer 2. In specific implementation, the buffer rubber strip 21 is fixedly connected with the claw body 341, which can effectively buffer the rigid contact during extrusion and reduce the damage of the claw body 341.

[0050] Working principle: By setting the phase change layer 3 and the heat dissipation layer 4, the heat in the power distribution cabinet can be timely absorbed and dissipated through the heat dissipation layer 4, reducing the case that the energy continues to appear inside the cabinet 1 due to the temperature being too high, and ensuring the integrity of the explosion-proof.

[0051] The above is the preferred embodiment of the present application, which does not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
