Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a moisture-proof high and low voltage power distribution cabinet for electric power engineering. Background Art

[0002] The power distribution cabinet is a general term for the motor control center, which mainly includes high-voltage circuit breakers, high-voltage disconnectors and grounding 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. It is also divided into high-voltage distribution cabinets and low-voltage distribution cabinets. The high-voltage distribution cabinet is mainly used to receive and distribute electric energy of 10kV and above. It is a key equipment in places such as substations and factory power supply systems. It can introduce high-voltage power supply, control it through circuit breakers, disconnectors and other equipment, and distribute electric energy to various lower-level power equipment or areas. The low-voltage distribution cabinet is mainly used to distribute and control 380V / 220V low-voltage electric energy. It is the power distribution center of buildings, small factories and other places, and distributes the low-voltage electricity output by the transformer to various power equipment, such as lighting, sockets, motors, etc.

[0003] Whether it is a high-voltage distribution cabinet or a low-voltage distribution cabinet, when it encounters rainy days outdoors, a lot of rainwater will adhere to the surface, causing the distribution cabinet to be in a wet state for a long time. If the wet rainwater on the surface of the distribution cabinet cannot be removed in time, the humidity inside the distribution cabinet will gradually increase. Therefore, we proposed a moisture-proof high and low voltage distribution cabinet for power engineering. Summary of the invention

At the same time, the rainwater accumulated on the surface of the fan-shaped inclined plate 2 506 is also discharged toward the outside by the thrust or is discharged toward the outside through the water-passing circular hole 509. The external scraper rod 508 is in contact with the outer surface of the rain shield circular plate 507 at all times when rotating, and the rotating external scraper rod 508 scrapes and cleans the outer surface of the rain shield circular plate 507.

[0055] When the present invention is in operation, the air inside the cabinet 1 is discharged to the outside from the side circular hole 6 through the ventilation device 5, and at the same time, the external air enters the cabinet 1 from the top circular hole 7 on the top of the cabinet 1 through the drying of the drying device 4. The cooperation between the ventilation device 5 and the drying device 4 allows the air inside and outside the cabinet 1 to circulate. When encountering rainy weather and too much rainwater adheres to the surface of the cabinet 1 for a long time, the rainwater on the surface of the cabinet 1 is wiped and absorbed through the moisture-proof dehumidification device 3, and the servo motor 303 is started to drive the threaded long rod 304 to rotate. When the threaded long rod 304 rotates, it drives the limited long rod 302 to penetrate the limited and threaded frame-shaped pressing plate 306 to move downward, and when the frame-shaped pressing plate 306 moves downward, it drives the frame-shaped sponge plate 305 and the connecting spring 306 at the bottom. 08. The frame-shaped bottom plate 309 and the frame-shaped plugging plate 310 move downward together. When the frame-shaped sponge plate 305 moves downward, the inner side surface is always in contact with the outer surface of the cabinet 1. The frame-shaped sponge plate 305 that moves downward contacts the surface of the cabinet 1 to wipe and absorb rainwater from the surface of the cabinet 1. When the frame-shaped bottom plate 309 moves downward to the bottom surface and contacts the ground, it is resisted and stops moving. When the frame-shaped bottom plate 309 stops moving, the top frame-shaped plugging plate 310 also stops moving. At this time, the frame-shaped pressing plate 306 continues to move downward to compress the connecting spring 308 at the bottom. At the same time, the frame-shaped sponge plate 305 also continues to move downward with the frame-shaped pressing plate 306. When the frame-shaped sponge plate 305 moves downward to contact the top of the frame plugging plate 310, the frame plugging plate 310 is set from the frame sponge plate 308 through the bevel setting of its top surface. 5, by arranging a frame-shaped inserting plate 310 on the top of the frame-shaped bottom plate 309 and inserting it into the inside of the frame-shaped sponge plate 305 to isolate the frame-shaped sponge plate 305 from the surface of the cabinet 1, the frame-shaped sponge plate 305 gradually moves down to the bottom surface and is constantly squeezed by the frame-shaped pressing plate 306 when it contacts the frame-shaped bottom plate 309, and the frame-shaped sponge plate 305 is squeezed and drained by the cooperation of the frame-shaped pressing plate 306 and the frame-shaped bottom plate 309. After the frame-shaped sponge plate 305 is drained, the frame-shaped pressing plate 306 can be driven by the threaded long rod 304 to move up to release the compression of the frame-shaped sponge plate 305 and the connecting spring 308, and the connecting spring 308 drives the fixedly connected frame-shaped sponge plate 305 to expand and recover through the extension force, and when it is not necessary to wipe off the accumulated water, the threaded long rod 304 can be used to The frame bottom plate 309, the frame sponge plate and the frame pressure plate 306 can be moved up to the top of the cabinet door 2. After the gas inside the cabinet 1 is discharged by the ventilation device 5, the external gas will pass through the dust screening circular hole 1 403 and enter between the frame sleeve plate 1 402 and the frame sleeve plate 2 406. Under the guidance of the corrugated guide plate 404, it will contact with the bagged desiccant 405 and move to the top through the dust screening circular hole 2 407 to enter the square sleeve 401. The gas entering the square sleeve 401 will enter the cabinet 1 from the top circular hole 7. By opening a plurality of dust screening circular holes 403 on the surface of the frame sleeve plate 1 402, it is convenient for the gas to pass through and resist impurities such as dust. By arranging the bagged desiccant 405 on the surface of the corrugated guide plate 404, the incoming gas is dried.By setting a plurality of corrugated guide plates 404 between the frame-shaped sleeve plate 1 402 and the frame-shaped sleeve plate 2 406 to guide the incoming gas, by setting a square sleeve shell 401 on the top of the cabinet 1 to cover a large area of ​​the top surface of the cabinet 1, starting the driving motor 503 to drive the linkage rod 504 to rotate, the linkage rod 504 rotates to drive the outer fan-shaped inclined plate 1 505, the fan-shaped inclined plate 2 506 and the external scraper rod 508 to rotate together, by setting a rainproof circular plate 507 on the inner wall of the side circular hole 6 to protect the inside of the side circular hole 6 from rain over a large area, when the fan-shaped inclined plate 1 505 and the fan-shaped inclined plate 2 506 rotate, their inclined surface settings push the gas and rainwater inside the conical ring shell 501 to The side circular hole 6 is discharged outside to maintain ventilation while preventing rainwater from accumulating and infiltrating into the cabinet 1. The gas and rainwater inside the conical ring shell 501 are continuously discharged through the inclined surface settings of the fan-shaped inclined plate 1 505 and the fan-shaped inclined plate 2 506. The fan-shaped inclined plate 1 505 is arranged in the direction close to the drive motor 503 to assist the fan-shaped inclined plate 2 506 in discharging gas and rainwater. At the same time, the rainwater accumulated on the surface of the fan-shaped inclined plate 2 506 is also discharged to the outside by the thrust or through the water-passing circular hole 509. The external scraper rod 508 is in contact with the outer surface of the rain shield circular plate 507 at all times when rotating, and the rotating external scraper rod 508 scrapes and cleans the outer surface of the rain shield circular plate 507.
