Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and in particular to an intelligent explosion-proof distribution cabinet for a power transmission system. Background Art

[0002] A high-voltage distribution cabinet refers to an electrical product that plays roles such as on-off, control, or protection in power generation, transmission, distribution, power conversion, and consumption of a power system, with a voltage level of 3.6 kV to 550 kV. It mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switch cabinets. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] What is usually noted for a distribution cabinet used in a power transmission system is the explosion-proof of the distribution cabinet. The explosion-proof of traditional distribution cabinets usually relies on thick-walled metals. Thick-walled metals have poor heat dissipation performance, which easily leads to heat accumulation, and opening heat dissipation holes easily destroys the explosion-proof integrity. Summary of the Invention

[0004] To solve the problem that in the prior art, the explosion-proof of traditional distribution cabinets usually relies on thick-walled metals, thick-walled metals have poor heat dissipation performance, which easily leads to heat accumulation, and opening heat dissipation holes easily destroys the explosion-proof integrity, the present application provides an intelligent explosion-proof distribution cabinet for a power transmission system, and the specific solution is as follows.

[0005] An intelligent explosion-proof distribution cabinet for a power transmission system includes a cabinet body. A partition board is arranged inside the cabinet body. An explosion-proof chamber is arranged below the partition board, and electrical components are installed in the explosion-proof chamber. A control chamber is arranged above the partition board, and control components for controlling the electrical components are installed in the control chamber; An explosion-proof door is arranged at the explosion-proof chamber, and the explosion-proof door is hinged to the explosion-proof chamber. A control door is arranged at the control chamber, and the control door is hinged to the control chamber. A control panel for displaying data of the electrical components and performing control is arranged on the control door; An explosion-proof layer and a phase change layer are arranged at the cabinet body at the explosion-proof chamber. The explosion-proof layer is arranged on the side close to the inside of the cabinet body. The phase change layer is arranged outside the explosion-proof layer and is used for absorbing and releasing heat. Heat pipes are also embedded in the phase change layer, and the heat pipes are used for absorbing heat. A heat dissipation layer is arranged outside the phase change layer, and a plurality of heat dissipation fins are arranged outside the heat dissipation layer.

[0006] By adopting the above technical solutions, the partition design between the explosion-proof chamber and the control chamber effectively improves the rationality of the functional partition of the power distribution cabinet, ensures the independence of electrical components and control components, and enhances 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 effectively alleviates the influence of temperature fluctuations on the equipment by absorbing and releasing heat, and at the same time, the embedding of heat pipes further enhances the heat conduction efficiency. The design of the heat dissipation layer and heat dissipation fins realizes efficient external heat dissipation, ensures the stable operation of the power distribution cabinet under high load conditions, and extends the service life of the equipment.

[0007] Optionally, a plurality of installation grooves are provided in the phase-change layer, adjustment push rods are provided in the installation grooves, the adjustment push rods are arranged at the joints of the explosion-proof layer, one end of the adjustment push rod is fixedly connected to the phase-change layer, and an adjustment clamping jaw is arranged at the other end of the adjustment push rod. The adjustment clamping jaw can abut against three sides of the explosion-proof layer, and the adjustment push rod can push the adjustment clamping jaw to squeeze the explosion-proof layer.

[0008] By adopting the above technical solutions, installation grooves and adjustment push rods are provided in the phase-change layer of the explosion-proof power distribution cabinet. The adjustment push rods abut against and apply pressure to three sides of the explosion-proof layer through the adjustment clamping jaws, thereby enhancing the sealing performance and stability of the explosion-proof layer at the joints. The pushing action of the adjustment push rods can adjust the stress state of the explosion-proof layer according to actual needs, reduce the situation that gaps appear on the joint surface of the explosion-proof layer and affect the explosion-proof performance, and further improve the explosion-proof performance.

[0009] Optionally, the adjustment clamping jaw includes a jaw seat and jaw bodies. The jaw bodies are circumferentially and equidistantly arranged at intervals around the jaw seat. The jaw seat is fixedly arranged at the end of the adjustment push rod. An articulated rod is arranged between the jaw body and the jaw seat. One end of the articulated rod is articulated with the jaw body, and the other end of the articulated rod is articulated with the jaw seat. An articulated rod is also arranged between the jaw body and the adjustment push rod. One end of the articulated rod is articulated with the jaw body, and the other end of the articulated rod is articulated with the adjustment push rod.

[0010] By adopting the above technical solutions, the structural design of the adjustment clamping jaw enables the jaw bodies to be circumferentially and equidistantly arranged at intervals around the jaw seat, thereby realizing uniform clamping of the explosion-proof layer. The arrangement of the articulated rods forms a flexible linkage structure between the jaw bodies, the jaw seat and the adjustment push rod. When the adjustment push rod is pushed, the articulated rods can drive the jaw bodies to act, enabling the jaw bodies to accurately abut against and squeeze 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.

[0011] Optionally, a circulation pipe is provided in the heat dissipation layer. The circulation pipe is connected end to end. A coolant is used to be introduced into the circulation pipe. An explosion-proof pump is arranged on the circulation pipe, and the explosion-proof pump is used to drive the coolant in the circulation pipe to flow.

[0012] By adopting the above technical solution, a circulation pipe is arranged in the heat dissipation layer and coolant is introduced, which can effectively absorb the heat transferred by the phase change layer and improve the heat dissipation efficiency. The explosion-proof pump drives the coolant to flow, ensuring that the coolant is evenly distributed in the entire circulation pipe, thereby achieving comprehensive cooling of the heat dissipation layer. This design helps to maintain the internal temperature stability of the power distribution cabinet and improve the working reliability of electrical components.

[0013] Optionally, the heat dissipation fins are arranged at equal intervals along the heat dissipation layer, and each of the heat dissipation fins is arranged in parallel. The circulation pipe is arranged in a bent manner along the heat dissipation fins, and a circulation pipe is provided between the heat dissipation fins.

[0014] By adopting the above technical solution, the heat dissipation fins are arranged at equal intervals along the heat dissipation layer and arranged in parallel, which can effectively increase the heat dissipation area and optimize the heat dissipation path, thereby improving the heat dissipation efficiency. The circulation pipe is arranged in a bent manner along the heat dissipation fins and distributed between the heat dissipation fins, ensuring that the coolant flows through each heat dissipation fin, achieving uniform heat dissipation, and further improving the overall heat dissipation performance.

[0015] Optionally, a convex portion is provided on the heat dissipation layer corresponding to the circulation pipe. The convex portion protrudes towards the outside of the cabinet body, and the circulation pipe is embedded in the convex portion.

[0016] By adopting the above technical solution, the convex portion can effectively increase the contact area between the circulation pipe and the outside world, thereby further improving the heat dissipation effect.

[0017] Optionally, a temperature sensor is provided on the heat dissipation layer. The temperature sensor is electrically connected to the explosion-proof pump. When the temperature sensor detects an increase in temperature, the rotation speed of the explosion-proof pump increases. When the temperature sensor detects a decrease in temperature, the rotation speed of the explosion-proof pump decreases.

[0018] By adopting the above technical solution, a temperature sensor is provided on the heat dissipation layer and electrically connected to the explosion-proof pump, enabling the explosion-proof pump to automatically adjust its rotation speed according to temperature changes. When the temperature rises, the rotation speed of the explosion-proof pump increases, accelerating the flow rate of the coolant in the circulation pipe and improving the heat dissipation efficiency. When the temperature drops, the rotation speed of the explosion-proof pump decreases, reducing energy consumption, achieving intelligent temperature control management, and improving the stability and energy conservation of equipment operation.

[0019] Optionally, a flow velocity sensor is arranged in the circulation pipe. The flow velocity sensor is electrically connected to the adjusting push rod. When the flow velocity sensor detects that the flow velocity is greater than the set value, the adjusting push rod pushes the adjusting jaw to perform a clamping action.

[0020] By adopting the above technical solutions, when the flow rate of the coolant in the circulation pipe is greater than the set value, the flow rate sensor can detect this change in state in a timely manner and trigger the movement of the adjustment push rod through electrical connection. The adjustment push rod pushes the adjustment jaw to perform a clamping action, thereby applying an additional fixing force to 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 cooling system is abnormal and the flow rate is too high, improving the overall safety and reliability of the power distribution cabinet.

[0021] Optionally, a buffer rubber strip is embedded on the side of the explosion-proof layer close to the phase change layer, and the buffer rubber strip is arranged in a cross shape.

[0022] By adopting the above technical solutions, embedding a buffer rubber strip at the explosion-proof layer and arranging the rubber strip in a cross shape can effectively absorb and disperse the stress generated by the phase change layer on the explosion-proof layer during thermal expansion and contraction, thereby improving the stability and service life of the explosion-proof layer, and at the same time reducing the risk of structural damage caused by stress concentration.

[0023] Optionally, a buffer rubber strip is also fixedly arranged on the claw body, and the buffer rubber strip is used to abut against the explosion-proof layer.

[0024] By adopting the above technical solutions, the setting of the buffer rubber strip can effectively reduce the rigid contact between the claw body and the explosion-proof layer, avoid damage to the explosion-proof layer caused by excessive clamping force, and at the same time improve the stability of clamping, ensure that the explosion-proof layer is evenly stressed when being squeezed, thereby improving the reliability and safety of the overall structure.

[0025] In summary, the present application has at least the following beneficial effects: 1. The present application solves the problem that in the prior art, the explosion protection of traditional power distribution cabinets usually relies on thick-walled metals, which have poor heat dissipation performance and are prone to heat accumulation, while opening heat dissipation holes easily destroys the explosion-proof integrity. By setting a phase change layer and a heat dissipation layer, the present application can timely absorb the heat in the power distribution cabinet and dissipate it through the heat dissipation layer, reducing the situation of energy continuation inside the cabinet due to too high temperature, and at the same time ensuring the explosion-proof integrity.

[0026] 2. The present application also sets a circulation pipe that can cool the heat dissipation layer, sets a temperature sensor at the heat dissipation layer, and sets a flow rate sensor in the circulation pipe. By timely judging the temperature of the explosion-proof layer at the heat dissipation layer and making a real-time response to improve the heat dissipation efficiency. Since it takes a certain amount of time for the flow rate of the coolant to increase to the specified value, when the flow rate sensor detects that the adjustment 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 can be adjusted, improving the accuracy of the adjustment of the explosion-proof layer and reducing the situation where the adjustment effect is reduced due to repeated adjustment that affects the adjustment jaw because it is impossible to judge when adjustment is needed.

Detailed implementation manners

[0033] The following further details the present application with reference to the accompanying drawings through specific embodiments.

[0034] An intelligent explosion-proof power distribution cabinet for a power transmission system, as Figure 1 and Figure 2 shown, includes a cabinet body 1. A partition board 11 is arranged inside the cabinet body 1. An explosion-proof bin 12 is arranged on the lower side of the partition board 11, and electrical components are installed in the explosion-proof bin 12. A control bin 13 is arranged on the upper side of the partition board 11, and control components for controlling the electrical components are installed in the control bin 13. An explosion-proof door 121 is arranged at the explosion-proof bin 12, and the explosion-proof door 121 is hinged to the explosion-proof bin 12. A control door 131 is arranged at the control bin 13, and the control door 131 is hinged to the control bin 13. A control panel 132 for displaying data of the electrical components and performing control is arranged on the control door 131. During specific implementation, both the explosion-proof bin 12 and the partition board 11 are made of thick-walled metal for explosion protection, while the control bin 13 is made of thinner metal to reduce the weight of the overall cabinet body 1.

[0035] As Figure 2 and Figure 3As shown in the figure, an explosion-proof layer 2 and a phase change layer 3 are provided at the cabinet body 1 at the explosion-proof bin 12. The explosion-proof layer 2 is provided on the side close to the inside of the cabinet body 1, and the phase change layer 3 is provided on the outside of the explosion-proof layer 2 and is used to absorb and release heat. Heat pipes 31 are also embedded in the phase change layer 3, and the heat pipes 31 are used to absorb heat. A heat dissipation layer 4 is provided on the outside of the phase change layer 3, and a plurality of heat dissipation fins 43 are provided on the outside of the heat dissipation layer 4. During 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 outside the heat source. The phase change layer 3 and the heat pipe 31 can achieve an efficient directional heat conduction effect. During installation, the position of the heat pipe 31 can be adjusted according to the installation position of the electrical components, so as to achieve precise positioning and heat dissipation of the electrical components, thereby further improving the cooling effect.

[0036] As Figure 2 and Figure 3 shown in the figure, a plurality of installation grooves 32 are provided in the phase change layer 3, and adjusting push rods 33 are provided in the installation grooves 32. The adjusting push rods 33 are provided at the joint of the explosion-proof layer 2. One end of the adjusting push rod 33 is fixedly connected to the phase change layer 3, and the other end of the adjusting push rod 33 is provided with an adjusting jaw 34. The adjusting jaw 34 can abut against three sides of the explosion-proof layer 2, and the adjusting push rod 33 can push the adjusting jaw 34 to squeeze the explosion-proof layer 2. During specific implementation, the adjusting push rod 33 adopts an industrial-grade high-power electric push rod, which can effectively compress the joint surface of the explosion-proof layer 2, and is safer than air cylinders and oil cylinders, reducing the situation of explosion-proof failure caused by gaps and other problems in the joint surface of the explosion-proof layer 2 due to high-temperature deformation, etc., and further improving the explosion-proof effect.

[0037] As Figure 4 shown in the figure, the adjusting jaw 34 includes a jaw seat 342 and jaw bodies 341. The jaw bodies 341 are circumferentially and equidistantly spaced around the jaw seat 342. The jaw seat 342 is fixedly provided at the end of the adjusting push rod 33. An articulated rod 343 is provided between the jaw body 341 and the jaw seat 342. One end of the articulated rod 343 is articulated with the jaw body 341, and the other end of the articulated rod 343 is articulated with the jaw seat 342. An articulated rod 343 is also provided between the jaw body 341 and the adjusting push rod 33. One end of the articulated rod 343 is articulated with the jaw body 341, and the other end of the articulated rod 343 is articulated with the adjusting push rod 33. During specific implementation, when the adjusting push rod 33 is pushed, it can drive the jaw body 341 to rotate, so as to drive the jaw body 341 to adjust the joint surface from three directions, thereby further improving the explosion-proof effect.

[0038] As Figure 2 and Figure 3As shown, a circulation pipe 41 is provided inside the heat dissipation layer 4. The circulation pipe 41 is connected end to end, and the circulation pipe 41 is used to pass through a coolant. An explosion-proof pump 42 is provided on the circulation pipe 41, and the explosion-proof pump 42 is used to drive the coolant in the circulation pipe 41 to flow. In specific implementation, the coolant in the circulation pipe 41 uses water or other media with a high specific heat capacity to absorb and release heat through continuous flow.

[0039] As Figure 1 and Figure 2 shown, heat dissipation fins 43 are arranged at equal intervals along the heat dissipation layer 4. Each heat dissipation fin 43 is arranged in parallel. The circulation pipe 41 is arranged along the heat dissipation fin 43 in a bent manner, and the circulation pipe 41 is provided between the heat dissipation fins 43. A convex portion 44 is provided on the heat dissipation layer 4 corresponding to the circulation pipe 41. The convex portion 44 protrudes towards the outside of the cabinet 1, and the circulation pipe 41 is embedded in the convex portion 44. In specific implementation, when the coolant flows between the heat dissipation fins 43, it can effectively contact the convex portion 44 and the wind blowing from the outside, 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.

[0040] As Figure 1 and Figure 3 shown, a temperature sensor 45 is provided on the heat dissipation layer 4. The temperature sensor 45 is electrically connected to the explosion-proof pump 42. When the temperature sensor 45 detects an increase in temperature, the rotation speed of the explosion-proof pump 42 increases. When the temperature sensor 45 detects a decrease in temperature, the rotation speed of the explosion-proof pump 42 decreases. A flow velocity sensor 46 is provided inside the circulation pipe 41. The flow velocity sensor 46 is electrically connected to the adjustment push rod 33. When the flow velocity sensor 46 detects that the flow velocity is greater than the set value, the adjustment push rod 33 pushes the adjustment jaw 34 to perform a clamping action. In specific implementation, when the temperature increases, the rotation speed of the explosion-proof pump 42 increases, thereby increasing the flow velocity of the coolant, increasing the heat exchange frequency of the coolant, and thus improving the heat dissipation effect. When the temperature continues to increase, attention needs to be paid to whether the explosion-proof layer 2 deforms accordingly. If the coolant has a high flow velocity, it indicates that a 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 timely adjust the joint surface of the explosion-proof layer 2, 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 temperature changes and quickly dissipate heat. Judging whether the explosion-proof layer 2 needs to be adjusted through the flow velocity sensor 46 is because when the temperature is within a controllable range, the coolant can control the temperature during the process of increasing flow velocity, and at this time, there is no need to start the adjustment push rod 33 to push. Only in an uncontrollable state where heat cannot be dissipated for a long time, the flow velocity will continuously increase and trigger the flow velocity sensor 46, reducing the situation that the adjustment push rod 33 affects the adjustment effect due to misjudging the adjustment conditions and repeatedly moving.

[0041] As Figure 5As shown, a buffer rubber strip 21 is embedded on the side of the explosion-proof layer 2 close to the phase change layer 3, and the buffer rubber strip 21 is arranged in a cross shape. During specific implementation, the buffer rubber strip 21 can provide multiple protections for the explosion-proof layer 2 during an actual explosion, further improving the explosion-proof effect.

[0042] As Figure 4 shown, a buffer rubber strip 21 is also fixedly arranged on the claw body 341, and the buffer rubber strip 21 is used to abut against the explosion-proof layer 2. During specific implementation, the buffer rubber strip 21 is fixedly connected to the claw body 341, which can effectively buffer the rigid contact during extrusion and reduce the damage of the claw body 341.

[0043] Working principle: By arranging the phase change layer 3 and the heat dissipation layer 4, the heat in the power distribution cabinet can be absorbed in time and dissipated through the heat dissipation layer 4, reducing the situation of energy continuation inside the cabinet 1 due to excessive temperature, and at the same time ensuring the integrity of explosion protection.

[0044] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
