Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a dual-power distribution cabinet with a moisture-proof and dehumidification structure. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The distribution cabinet is prone to moisture when in use. The main reason is that the internal contacts and electrical components of the cabinet will generate local heating due to long-term operation. The cabinet body is made of metal, and the surface temperature of the cabinet is lower than the internal heating components. The heat inside the distribution cabinet generates a temperature difference with the cabinet surface. The temperature difference will instantly saturate the unsaturated water vapor in the ambient air, causing condensation on the cabinet body or glass windows. The water vapor condensed in the cabinet body increases the humidity inside the cabinet, which can easily cause electrical components to become damp and short-circuit. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A dual-power distribution cabinet with a moisture-proof and dehumidification structure, comprising a cabinet, a rainproof rack is fixedly installed on the top of the cabinet, a protective door is rotatably installed on the outer surface of the cabinet, a lock is fixedly installed on one side of the outer surface of the cabinet, the lock is adapted to the protective door, and clamping grooves are opened on both sides of the outer surface of the cabinet;

[0005] An internal support assembly, which is used for dehumidification support of the components of the power distribution cabinet and is fixedly installed inside the cabinet;

The temperature difference between the internal distribution cabinet and the cabinet surface is generated due to the heat, and the temperature difference will instantly saturate the unsaturated water vapor in the ambient air, causing condensation on the cabinet or glass window, resulting in the electrical components being affected by the water vapor and causing a short circuit. Therefore, a dehumidifier is provided on the outside of the support plate carrying the electrical components to guide the condensed water vapor and transport the water vapor to the outside of the cabinet; when the cabinet is hit, the internal electrical components will collide with the inner wall of the cabinet, so when the cabinet is hit, the protective assembly installed inside the cabinet is squeezed to protect the electrical components.

[0008] The inner support assembly includes a dehumidifier, a support plate is fixedly installed inside the dehumidifier, and a guide groove is provided on the surface of the support plate, and the guide groove is adapted to the dehumidifier.

While the guide hole guides out part of the water vapor, since the guide hole is opened on both sides of the cabinet, and since the temperature inside the cabinet is higher than that outside the cabinet, the low-temperature gas outside the cabinet is transported into the cabinet along the guide hole, so that the low-temperature gas is transported along the semicircular tube and the circular groove to the guide groove set on the support plate, and the guide groove is set below the electrical component, so that the low-temperature gas cools the electrical component when passing through the guide groove, so as to reduce the temperature inside the cabinet and reduce the amount of water vapor condensation, and perform moisture-proof and dehumidification treatment on the cabinet.

[0012] Preferably, the support plate is fixedly mounted inside the positioning frame, a circular groove is provided on the surface of the positioning frame, and the guide groove is arranged opposite to the circular groove.

When the cabinet is hit, the interior of the cabinet is forced to be concave, and the positioning plate is squeezed, so that the positioning plate is displaced in the cavity of the cabinet, so that the protective member and the electrical components on the support plate are squeezed. Since the protective member is set to a flexible material, it can buffer the impact on the electrical components, thereby protecting the electrical components.

[0015] Preferably, a through plate penetrates the interior of the positioning block, and protective pieces are sleeved on both sides of the outer surface of the through plate, and the protective pieces are extruded and adapted to the components of the power distribution cabinet.

[0020] 2. The dual-power distribution cabinet with a moisture-proof and dehumidification structure, while guiding out part of the water vapor through the guide holes, because the guide holes are opened on both sides of the cabinet, and because the temperature inside the cabinet is higher than that outside the cabinet, the low-temperature gas outside the cabinet is transported into the cabinet along the guide holes, so that the low-temperature gas is transported along the semicircular tube and the circular groove to the guide groove arranged on the support plate, and the guide groove is arranged below the electrical components, so that the low-temperature gas cools the electrical components when passing through the guide groove, so as to reduce the temperature inside the cabinet and reduce the amount of water vapor condensation, thereby performing moisture-proof and dehumidification treatment on the cabinet.

[0021] 3. The dual-power distribution cabinet with moisture-proof and dehumidification structure supports and fixes the support plate through a positioning frame. The water vapor condensed on the inner wall of the cabinet slides downward along the inner wall and slides into the semicircular pipe of the exhaust port, so that the water vapor is discharged from the cabinet along the guide hole and the exhaust port to eliminate the water vapor in the cabinet.

[0022] 4. The dual-power distribution cabinet with a moisture-proof and dehumidification structure, when the cabinet body is hit, the internal force of the cabinet body is depressed and the positioning plate is squeezed, so that the positioning plate is displaced in the cavity of the cabinet body, so that the protective part and the electrical components on the support plate are squeezed.

[0023] 5. The dual-power distribution cabinet with a moisture-proof and dehumidification structure, when the protective part is squeezed, the gasket moves toward the surface of the electrical component along the position of the depression caused by the impact, so that the gasket becomes depressed and drives the bonding sheet to move to abut against the surface of the electrical component, so as to reduce the impact force on the electrical component and prevent the electrical component from being damaged and causing a short circuit.

[0037] An inner support assembly 3, which is used for dehumidification support of the components of the power distribution cabinet, and the inner support assembly 3 is fixedly installed inside the cabinet body 2;

[0038] A protection component 5, which is used for protecting components of the power distribution cabinet and is fixedly mounted on both sides of the inner wall of the cabinet body 2;

[0039] The rainproof rack 1 is fixedly installed in the middle of the top of the cabinet 2, and there are two groups of snap-in grooves 6, which are symmetrically arranged with the cabinet 2 as the center, and the inner support component 3 is fixedly installed in the interior of the cabinet 2 through the snap-in grooves 6; when the distribution cabinet is in long-term operation, the internal electrical components will produce local heating, and the cabinet 2 is made of metal, and the surface temperature of the cabinet 2 is relatively low compared to the internal heating components. The temperature difference between the internal distribution cabinet and the surface of the cabinet 2 is generated due to the heat, and the temperature difference will instantly saturate the unsaturated water vapor in the ambient air. When condensation occurs on the cabinet 2 or the glass window, the electrical components are affected by the water vapor and a short circuit occurs. Therefore, a dehumidifier 32 is provided on the outside of the support plate 31 carrying the electrical components to guide the condensed water vapor and transport the water vapor to the outside of the cabinet 2; when the cabinet 2 is hit, the internal electrical components will collide with the inner wall of the cabinet 2, so when the cabinet 2 is hit, the protective component 5 installed inside the cabinet 2 is squeezed to protect the electrical components.

[0040] The second embodiment is based on the first embodiment. Figures 3 to 6 As shown, the inner support assembly 3 includes a dehumidifying component 32, a support plate 31 is fixedly installed inside the dehumidifying component 32, and a guide groove 33 is provided on the surface of the support plate 31, and the guide groove 33 is adapted to the dehumidifying component 32. When water vapor condenses in the cabinet 2, the water vapor adheres to the inner wall of the cabinet 2, and as the water vapor continues to condense and slides downward along the inner wall of the cabinet 2, the water vapor is discharged from the cabinet 2 along the dehumidifying component 32, and the air outside the cabinet 2 is transported into the cabinet 2 along the dehumidifying component 32, and flows along the guide groove 33 provided on the surface of the support plate 31 at the bottom of the electrical components, so as to cool down the high-temperature electrical components placed on the support plate 31.

[0041] The dehumidifying components 32 are provided in two groups, and both groups of the dehumidifying components 32 are fixedly installed inside the clamping groove 6, and the dehumidifying components 32 are fixedly connected to the inner wall of the cabinet 2, and the top of the support plate 31 is fixedly connected to the distribution cabinet component.

[0042] The dehumidifying element 32 includes a positioning frame 323 , a frame plate 324 is fixedly mounted on the bottom of the positioning frame 323 , a fixing plate 321 is fixedly mounted on the outer surface of the positioning frame 323 , and outer frame plates 322 are fixedly mounted on both ends of the outer surface of the fixing plate 321 .

[0043] The surface of the outer frame plate 322 is provided with a guide hole 325, and a semicircular tube 327 is fixedly installed between the guide hole 325 and the opposite surface of the positioning frame 323. While the guide hole 325 guides out part of the water vapor, since the guide hole 325 is opened on both sides of the cabinet 2, and since the temperature inside the cabinet 2 is higher than that outside the cabinet 2, at this time, the low-temperature gas outside the cabinet is transported into the cabinet 2 along the guide hole 325, so that the low-temperature gas is transported to the guide groove 33 set on the support plate 31 along the semicircular tube 327 and the circular groove 326. The guide groove 33 is set below the electrical components, so that the low-temperature gas cools the electrical components when passing through the guide groove 33, so as to reduce the temperature inside the cabinet 2 and reduce the amount of water vapor condensation, and perform moisture-proof and dehumidification treatment on the cabinet 2.

[0044] The support plate 31 is fixedly installed inside the positioning frame 323 . A circular groove 326 is formed on the surface of the positioning frame 323 . The guide groove 33 is arranged opposite to the circular groove 326 .

[0045] The frame plate 324 is fixedly installed inside the clamping groove 6, and the frame plate 324 penetrates the clamping groove 6 and extends to the outside of the cabinet 2. The frame plate 324 is arranged below the outer frame plate 322, and a drainage port 328 is arranged between the positioning frame 323, the outer frame plate 322 and the frame plate 324. The positioning frame 323 supports and fixes the support plate 31, and the water vapor condensed on the inner wall of the cabinet 2 slides downward along the inner wall and slides into the semicircular tube 327 of the drainage port 328, so that the water vapor is discharged from the cabinet 2 along the guide hole 325 and the drainage port 328 to eliminate the water vapor in the cabinet 2.

[0046] The third embodiment is based on the first and second embodiments. Figures 7 to 10 As shown, the protection component 5 includes a positioning plate 55, which is fixedly mounted on the inner wall of the cabinet 2, and a middle plate 51 is fixedly mounted on the outer surface of the positioning plate 55, and a positioning block 53 is fixedly mounted in the middle of the outer surface of the middle plate 51. When the cabinet 2 is hit, the inside of the cabinet 2 is forced to be concave, and the positioning plate 55 is squeezed, so that the positioning plate 55 is displaced in the cavity of the cabinet 2, so that the protective member 52 and the electrical components on the support plate 31 are squeezed. Since the protective member 52 is set to a flexible material, it can buffer the impact on the electrical components, thereby protecting the electrical components.

[0047] A through plate 54 penetrates the interior of the positioning block 53 , and protective members 52 are sleeved on both sides of the outer surface of the through plate 54 . The protective members 52 are pressed and adapted to the components of the power distribution cabinet.

[0048] The protective member 52 includes a sleeve pad 523, the interior of which is provided with a through slot 524, the through slot 524 being sleeved on both ends of the outer surface of the through plate 54, the outer surface of the sleeve pad 523 is fixedly mounted with a connecting block 521, two connecting blocks 521 are provided, and the outer surfaces of the two connecting blocks 521 are fixedly mounted with a bonding sheet 522. When the protective member 52 is squeezed, the sleeve pad 523 moves toward the surface of the electrical component along with the position of the depression caused by the impact, so that the sleeve pad 523 is depressed, and the bonding sheet 522 is moved to abut against the surface of the electrical component, so as to reduce the impact force on the electrical component and prevent the electrical component from being damaged and causing a short circuit.

[0049] The connection block 521 is symmetrically arranged with the positioning block 53 as the center, and the connection block 521 is squeezed and adapted to the inner wall of the cabinet 2. The fitting sheet 522 is set to a flexible material, and the fitting sheet 522 is adapted to the components of the distribution cabinet.

[0050] During use, the internal electrical components will generate local heating due to the long-term operation of the distribution cabinet. The cabinet body 2 is made of metal, and the surface temperature of the cabinet body 2 is relatively low compared to the internal heating components. The heat inside the distribution cabinet generates a temperature difference with the surface of the cabinet body 2. The temperature difference will instantly saturate the unsaturated water vapor in the ambient air, and condensation will occur on the cabinet body 2 or the glass window, causing the electrical components to be affected by the water vapor and cause a short circuit. Therefore, a dehumidifier 32 is provided on the outside of the support plate 31 that carries the electrical components to guide the condensed water vapor and transport the water vapor to the outside of the cabinet body 2; when the cabinet body 2 is hit, the internal electrical components will collide with the inner wall of the cabinet body 2. Therefore, when the cabinet body 2 is hit, the protective component 5 installed inside the cabinet body 2 is squeezed to protect the electrical components.

[0051] When water vapor condenses in the cabinet 2, the water vapor adheres to the inner wall of the cabinet 2. As the water vapor continues to condense and slides downward along the inner wall of the cabinet 2, the water vapor is discharged from the cabinet 2 along the dehumidification element 32, and the air outside the cabinet 2 is transported into the cabinet 2 along the dehumidification element 32, and flows along the guide groove 33 opened on the surface of the support plate 31 at the bottom of the electrical components to cool the high-temperature electrical components placed on the support plate 31.

[0052] While the guide hole 325 is guiding out part of the water vapor, since the guide hole 325 is opened on both sides of the cabinet 2, and since the temperature inside the cabinet 2 is higher than that outside the cabinet 2, the low-temperature gas outside the cabinet is transported into the cabinet 2 along the guide hole 325, so that the low-temperature gas is transported along the semicircular tube 327 and the circular groove 326 to the guide groove 33 set on the support plate 31. The guide groove 33 is set below the electrical components, so that the low-temperature gas cools the electrical components when passing through the guide groove 33, so as to reduce the temperature inside the cabinet 2 and reduce the amount of water vapor condensation, thereby performing moisture-proof and dehumidification treatment on the cabinet 2.

[0053] The positioning frame 323 supports and fixes the support plate 31, and the water vapor condensed on the inner wall of the cabinet 2 slides downward along the inner wall and slides into the semicircular tube 327 of the exhaust port 328, so that the water vapor is discharged from the cabinet 2 along the guide hole 325 and the exhaust port 328 to eliminate the water vapor in the cabinet 2.

[0054] When the cabinet 2 is hit, the interior of the cabinet 2 is forced to be concave and squeeze the positioning plate 55, causing the positioning plate 55 to move in the cavity of the cabinet 2, so that the protective member 52 and the electrical components on the support plate 31 are squeezed. Since the protective member 52 is set to a flexible material, it can buffer the impact on the electrical components, thereby protecting the electrical components.

[0055] When the protective member 52 is squeezed, the sleeve pad 523 moves toward the surface of the electrical component along with the depressed position caused by the impact, so that the sleeve pad 523 is depressed and drives the bonding sheet 522 to move to abut against the surface of the electrical component, thereby reducing the impact force on the electrical component and preventing damage to the electrical component from causing a short circuit.

[0056] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
