Description

Technical Field

[0002] A high-voltage switchgear cabinet is a key device in the power system for distributing, controlling, and protecting electric energy, and is widely used in substation, industrial and mining enterprises, and large building power distribution systems. Its core functions include closing and opening of normal circuits, rapid cut-off during faults (such as short circuits or overloads), and isolation of live parts to ensure maintenance safety. With the development of smart grids, modern high-voltage switchgear cabinets are gradually integrated with digital monitoring (such as temperature and partial discharge sensors), remote control, and status assessment functions, and the voltage levels generally cover 3.6 kV to 40.5 kV. A typical structure consists of modules such as circuit breakers, disconnectors, instrument transformers, and protection devices, and adopts a metal-enclosed design to improve the protection performance (IP rating) and safety (such as five-prevention interlocking).

[0003] Currently, in an environment with large day-night temperature differences, a large amount of condensation is likely to occur inside the outdoor high-voltage switchgear cabinet due to sudden temperature changes.

[0040] Embodiment 1

[0041] Referring to Figures 1-9 , for the first embodiment of the present invention, an intelligent dehumidifying high-voltage switch cabinet is provided. This device includes:

[0042] A carrying mechanism 100, including a cabinet body 110, a mounting rack 120 fixedly installed in the inner cavity of the cabinet body 110, and a drying and moisture absorption component 130 for maintaining the dryness inside the cabinet body 110;

[0043] A dehumidifying mechanism 200, including a partition 210 fixedly installed in the inner cavity of the cabinet body 110, a mounting component 220 arranged in the inner cavity of the cabinet body 110, a main dehumidifying component 230 arranged in the mounting component 220 to achieve automatic dehumidification, a drainage component 240 arranged at the bottom of the main dehumidifying component 230, and a collection component 250 arranged at the bottom of the drainage component 240 for concentrating water for isolation;

[0044] The main dehumidifying component 230 includes a collection trough box 231, a damping seat 232 fixedly installed in the inner cavity of the collection trough box 231, a damping shaft sleeve 233 engaged with the damping seat 232, a rotating rod 234 fixedly installed on the outer side of the damping shaft sleeve 233 for adjusting the inclination angle, a passive condensation and dew collection plate 235 fixedly installed at the bottom of the rotating rod 234, and a water diversion inclined surface 236 arranged at an inclined angle on one side of the collection trough box 231;

[0045] And a refrigeration mechanism 300 used in cooperation with the bearing mechanism 100.

[0046] Among them, through the cooperation of the cabinet body 110 and the mounting bracket 120, a stable installation foundation is formed, so that the internal components are firmly installed under high-pressure environments; through the meshing cooperation of the damping seat 232 and the damping bushing 233, the stability and reliability of the angle adjustment of the rotating rod 234 are achieved; the fixed connection method between the passive condensation and dew collection plate 235 and the rotating rod 234 ensures the accurate positioning of the condensation surface; the inclined design of the water diversion slope 236 provides a structural basis for the directional diversion of condensed water, and the whole constitutes a complete set of passive dehumidification systems, which are characterized by a compact structure and reliable operation.

[0047] Specifically, an air circulation channel that penetrates up and down is provided in the inner cavity of the collection trough box 231 to achieve rapid convection of the air inside the cabinet body 110.

[0048] Among them, the design of the air circulation channel that penetrates up and down effectively promotes the natural convection cycle of the air inside the cabinet body 110. It not only ensures the full flow of the air around the active dehumidification component 230 to improve the dehumidification efficiency, but also avoids the problem of local moisture accumulation that may be caused by the traditional closed structure, and realizes uniform dehumidification of the air inside the cabinet body 110.

[0049] Furthermore, the water diversion slope 236 slopes downward from the top opening of the collection trough box 231 to the bottom opening, and the opening gradually becomes smaller downward.

[0050] Among them, the inclined structure of the water diversion slope 236 ensures that the condensed water naturally flows to the designated position under the action of gravity; the structural feature of the gradually decreasing opening not only ensures the large-flow water collection capacity in the initial stage, but also improves the water flow speed through the narrowing design at the end, effectively preventing water droplet residue and secondary evaporation, and significantly enhancing the drainage efficiency.

[0051] Preferably, the drainage component 240 includes a square pipe 241 fixedly installed in the inner cavity of the partition plate 210, a shaft rod 242 rotatably installed on one side of the bottom of the square pipe 241, a pressing cover plate 243 fixedly installed on the outside of the shaft rod 242 for passive downward drainage, and a drainage slope 244 provided on the outside of the pressing cover plate 243. The drainage component 240 further includes a sealing strip 245 fixedly installed on the other side of the square pipe 241 and in contact with the drainage slope 244, a side plate 246 fixedly installed on the outside of the square pipe 241, and a telescopic spring 247 fixedly installed on the outside of the side plate 246 and vertically installed. The end of the telescopic spring 247 is fixedly connected to the bottom of the pressing cover plate 243.

[0052] Among them, the rotational cooperation between the shaft rod 242 and the lower pressing cover plate 243 realizes the one-way drainage function. When the water is collected to a certain extent and the pressure reaches the threshold value, the drainage is automatically opened, and after drainage, it is automatically closed through the elastic reset function of the telescopic spring 247; the coordinated action of the drainage slope 244 and the sealing strip 245 ensures complete sealing during the drainage process, effectively preventing the backflow of moisture; the reinforcement design of the side plate 246 enhances the overall structural strength, and the vertical installation method of the telescopic spring 247 provides a stable pre-tightening force, ensuring the quick response and reliable sealing of the lower pressing cover plate 243, achieving the perfect combination of passive automatic drainage and reliable sealing, and having the remarkable advantages of high drainage efficiency, good sealing performance, and long service life.

[0053] Further, the collection assembly 250 includes a water collection tank 251 movably clamped in the inner cavity of the cabinet body 110, a water absorption plate 252 movably placed in the inner cavity of the water collection tank 251, a drainage groove 253 opened at the top of the water absorption plate 252, and a breathable mesh plate 254 fixedly installed at the top of the drainage groove 253.

[0054] Among them, the movable arrangement of the water absorption plate 252 and the diversion structure of the drainage groove 253 can efficiently absorb and guide the condensate to flow in a directional manner, effectively preventing secondary evaporation; the fixed installation of the breathable mesh plate 254 not only ensures the air permeability of the drainage system to balance the air pressure, but also can effectively block impurities from entering and maintain the cleanliness of the water collection system.

[0055] It should be noted that the principle of the passive condensation dew collecting plate 235 is based on the temperature difference condensation effect. When the humid air inside the cabinet body 110 flows through the surface of the passive condensation dew collecting plate 235 with a large heat capacity, since the passive condensation dew collecting plate 235 forms a heat conduction path with the cabinet body 110 through the damping bushing 233, its surface temperature is always lower than the dew point temperature of the surrounding air, causing the water vapor in the air to undergo a phase change and condense into liquid water droplets on the plate surface; the inclined installation of the rotating rod 234 ensures that the condensed water flows directionally along the plate surface towards the water diversion slope 236 under the action of gravity, and at the same time, the meshing structure of the damping seat 232 maintains the stability of the plate surface angle, so that the condensation process is not affected by the vibration of the cabinet body. This design does not require external energy and realizes continuous dehumidification only through the thermodynamic characteristics of the material.

[0056] During use, the humid air inside the cabinet body 110 forms a convection through the ventilation channel of the collection trough box 231, condenses into water droplets after contacting the passive condensation dew collecting plate 235, and the water droplets flow into the drainage assembly 240 along the water diversion slope 236;

[0057] When the accumulated water reaches a certain amount, the water pressure pushes the lower pressing cover plate 243 to overcome the resistance of the telescopic spring 247 to open the drainage, and the water flows through the drainage slope 244 and is discharged into the collection assembly 250;

[0058] The water absorption plate 252 in the water collection tank 251 absorbs moisture and distributes it evenly through the drainage groove 253. The breathable mesh plate 254 maintains air pressure balance. At the same time, the drying and moisture absorption component 130 continuously adsorbs residual moisture, forming a complete dehumidification cycle.

[0059] In summary, through the collaborative cooperation of the bearing mechanism 100 and the dehumidification mechanism 200, an efficient and stable passive dehumidification function is achieved. The cabinet body 110 and the mounting frame 120 of the bearing mechanism 100 form a solid foundation, and the drying and moisture absorption component 130 ensures a dry environment inside the cabinet body 110. The passive condensation and dew collection plate 235 adopted by the dehumidification mechanism 200 cooperates with the adjustable angle structure to achieve efficient condensation dehumidification. The drainage component 240 ensures one-way drainage and prevents moisture backflow through the automatically opened and closed pressing cover plate 243 and the sealing structure. The collection component 250 not only ensures the effective collection of condensed water but also maintains air pressure balance through the breathable mesh plate 254. The overall structure has significant advantages such as compact structure, high dehumidification efficiency, reliable operation, and simple maintenance, effectively solving the condensation problem of high-voltage switchgear in outdoor environments and significantly improving the safety and service life of the equipment.

[0060] Embodiment 2

[0061] Refer to Figure 2 、 Figure 4 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is: an installation component 220 that can quickly disassemble and assemble the active dehumidification component 230.

[0062] Furthermore, the installation component 220 includes a housing 221 fixedly installed in the inner cavity of the cabinet body 110, a clamping plate 222 movably clamped in the inner cavity of the housing 221, a return spring 223 fixedly installed in the inner cavity of the housing 221, and a positioning protrusion 224 fixedly installed at the end of the return spring 223 and connected by a rotating shaft. The installation component 220 further includes a pull rod 225 rotatably installed outside the positioning protrusion 224, a support spring 226 fixedly installed in the inner cavity of the housing 221 for jacking up and down when the clamping plate 222 is released from clamping, and a cross plate 227 fixedly installed at the top of the support spring 226 for providing a supporting force. The outside of the collection trough box 231 is fixedly connected to the clamping plate 222.

[0063] Among them, through the movable clamping cooperation between the housing 221 and the clamping plate 222, and the operating mechanism of the positioning protrusion 224 and the pull rod 225 driven by the return spring 223, the quick disassembly and assembly function of the active dehumidification component 230 is realized. The synergistic effect of the support spring 226 and the cross plate 227 provides a jacking force during disassembly to ensure the stable separation of the active dehumidification component 230, significantly improving the maintenance efficiency. This structure realizes tool-free quick maintenance while ensuring the installation stability, solving the problem of inconvenient maintenance of traditional fixed installations.

[0064] During use, when it is necessary to disassemble the active dehumidification component 230, the operator pulls the pull rod 225 outwards to drive the positioning rib 224 to rotate, so that the clamping plate 222 releases the clamping state with the housing 221. At this time, the support spring 226 pushes the cross plate 227 upwards to assist the smooth separation of the active dehumidification component 230; during installation, just align the collection tank box 231 with the housing 221 and press it downwards. The clamping plate 222 automatically resets and clamps under the action of the return spring 223, and the positioning rib 224 ensures that the installation is in place. The disassembly and assembly operations can be completed without tools throughout the process.

[0065] In summary, the installation component 220 realizes the rapid disassembly and assembly of the active dehumidification component 230 through a spring-driven buckle mechanism, which not only ensures the stability during operation but also greatly improves the maintenance convenience, and is suitable for the application scenarios of outdoor high-voltage equipment that requires frequent maintenance.

[0066] Embodiment 3

[0067] Refer to Figure 6 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a drying and moisture-absorbing component 130 is provided to assist the active dehumidification component 230 to perform additional dehumidification on the inner cavity of the cabinet 110.

[0068] Furthermore, the drying and moisture-absorbing component 130 includes an orifice plate 131 installed on the outside of the mounting frame 120 through bolts, a trough box 132 fixedly installed on the outside of the orifice plate 131, a drying adsorption plate 133 movably placed in the inner cavity of the trough box 132, and a ventilation opening 134 opened on the outside of the trough box 132.

[0069] Among them, through the uniform air distribution effect of the orifice plate 131, the drying and moisture-absorbing component 130 enables the wet air to fully contact the drying adsorption plate 133 in the trough box 132 to achieve efficient moisture absorption; the ventilation opening 134 adopts an optimized design to promote the air circulation in the cabinet and avoid the accumulation of local moisture, thereby effectively reducing the overall humidity level in the cabinet 110. This structure realizes continuous and stable humidity control while ensuring mechanical strength.

[0070] During use, the humid air in the cabinet 110 enters the trough box 132 through the ventilation opening 134, is adsorbed and dehydrated after fully contacting the drying adsorption plate 133, and the dried air is recycled back into the cabinet 110; when the drying adsorption plate 133 is saturated, the trough box 132 can be disassembled and the drying adsorption plate 133 can be replaced. The design of the orifice plate 131 fixed by bolts ensures convenient disassembly and assembly.

[0071] In summary, the replaceable drying adsorption plate 133 in the trough box 132 provides continuous moisture absorption capacity, while the ventilation port 134 ensures air circulation in the cabinet body 110, enabling moisture to fully contact the adsorption material and cooperating with the active dehumidification component 230 to form a dual dehumidification guarantee, which is suitable for the long-term stable dehumidification requirements in extremely humid environments.

[0072] Embodiment 4

[0073] Referring to Figure 1 、 Figure 8 and Figure 9 , this is the fourth embodiment of the present invention. The difference between this embodiment and the second embodiment is that a refrigeration mechanism 300 for cooling the interior of the cabinet body 110 and its installation location are provided.

[0074] Furthermore, the bearing mechanism 100 further includes a cabinet door 140 hinged to the outside of the cabinet body 110, a side door 150 hinged to the outside of the cabinet body 110 for conveniently taking the water collection tank 251, and a through hole 160 opened on the side of the cabinet body 110 for hanging the refrigeration mechanism 300;

[0075] The refrigeration mechanism 300 includes a casing 310 installed in the inner cavity of the through hole 160 through a hanging member, a compressor 320 fixedly installed on one side of the top of the inner cavity of the casing 310, a centrifugal impeller 330 fixedly installed on the other side of the top of the inner cavity of the casing 310, heat dissipation fins 340 fixedly installed in the inner cavity of the casing 310, a middle partition 350 fixedly installed in the center of the inner cavity of the casing 310, a condenser 360 fixedly installed at the bottom of the middle partition 350, and an axial flow fan 370 fixedly installed at the bottom of the casing 310.

[0076] Among them, the through hole 160 and the hanging member realize the quick disassembly and assembly of the refrigeration casing 310. The compressor 320 and the condenser 360 are partitioned by the middle partition 350 to improve the heat dissipation efficiency; the centrifugal impeller 330 and the axial flow fan 370 form a two-way air flow cycle, and cooperate with the heat dissipation fins 340 to enhance the temperature reduction effect in the cabinet, effectively suppressing the condensation phenomenon caused by the temperature difference; the side door 150 and the modular water collection tank 251 design are convenient for maintenance; on the basis of maintaining the original dehumidification performance, this integrated structure further stabilizes the temperature and humidity in the cabinet through active refrigeration, completely solving the stubborn condensation problem in the large temperature difference environment, while taking into account the installation convenience and maintenance convenience.

[0077] During use, after the compressor 320 is started, the refrigerant is compressed into a high-temperature and high-pressure gas, pre-cooled by the heat dissipation fins 340 and then enters the condenser 360 to complete the phase change and release heat; the centrifugal impeller 330 sends cold air into the inner cavity of the cabinet body 110 along the upper part of the middle partition 350, and at the same time, the axial flow fan 370 sucks the hot air in the cabinet from the bottom to form forced convection; the refrigerant after heat exchange flows back to the compressor 320 through the lower part of the middle partition 350 to complete the cycle. The whole process realizes the quick heat exchange with the cabinet body 110 through the through hole 160.

[0078] In summary, the refrigeration mechanism 300 cooperates with the compressor 320 and the condenser 360 for refrigeration, and forms forced convection in cooperation with the centrifugal impeller 330 and the axial flow fan 370 to quickly reduce the temperature inside the cabinet; the heat dissipation fins 340 and the middle partition 350 optimize the heat dissipation path, the through holes 160 enable quick disassembly and assembly, and the cabinet door 140 and the side opening door 150 are convenient for maintenance, thus forming an active temperature control system that is efficient, stable and easy to maintain, and cooperating with the dehumidification mechanism 200 to assist in solving the problem of condensation inside the cabinet in a large temperature difference environment.
