Description

Technical Field

[0001] This utility model belongs to the field of electrical cabinet technology, specifically relating to a high-voltage outgoing cabinet for a substation. Background Technology

[0002] A high-voltage outgoing line cabinet is an electrical device that serves to segment, isolate, and protect circuits during use. Various types of components are installed inside the high-voltage outgoing line cabinet, and these components generate a lot of heat during operation. Therefore, the cabinet of the high-voltage outgoing line cabinet is usually equipped with heat dissipation vents. To prevent debris from entering the cabinet through the heat dissipation vents and damaging the components, filters are usually installed inside the heat dissipation vents.

[0003] However, during long-term use, a large amount of dust will accumulate on the filter screen of the high-voltage outgoing switchgear. The filter screen is usually fixed inside the heat dissipation vent, which needs to be removed for cleaning. This operation is troublesome. Furthermore, during the cleaning process, the heat dissipation vent is left unobstructed. Since the dust is light, the dust generated during cleaning can enter the high-voltage outgoing switchgear through the open heat dissipation vent, which can easily cause safety accidents. Utility Model Content

[0004] To overcome the problems in the prior art where the filter screen of a high-voltage outgoing switchgear is generally fixed inside the heat dissipation vent, requiring disassembly for cleaning, which is cumbersome, and where dust generated during cleaning can enter the high-voltage outgoing switchgear through the open vent, potentially causing safety accidents, this utility model provides a substation high-voltage outgoing switchgear. A telescopic mechanism extends the perforated heat dissipation plate and filter screen out of the heat dissipation vent of the switchgear, simultaneously causing a dust baffle to move downwards and automatically cover the vent. Cleaning and maintenance can be performed without disassembling the filter screen, simplifying operation, improving work efficiency, and preventing dust generated during cleaning from entering the high-voltage outgoing switchgear, thus avoiding safety accidents.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A substation high-voltage outgoing line cabinet mainly includes a cabinet body, a heat dissipation vent, a perforated heat dissipation plate, a filter screen, a telescopic mechanism, a dustproof baffle, and a connecting plate. The cabinet body has a heat dissipation vent on its side wall. The connecting plate is installed on the side wall of the cabinet body and has a rectangular slot that mates with the heat dissipation vent. The perforated heat dissipation plate is installed on the connecting plate through the telescopic mechanism and is located directly opposite the heat dissipation vent. The filter screen is installed on the inner wall of the perforated heat dissipation plate. A dustproof baffle that can slide up and down is installed on the connecting plate and is slidably installed on the connecting plate and connected to the telescopic mechanism.

[0006] The telescopic mechanism includes a first support rod, a second support rod, a connecting rod, and an electric push rod. The connecting plate has a first and a second straight slot on its side wall, and the perforated heat dissipation plate has a third straight slot on its side wall. One end of the first support rod is hinged to the side wall of the connecting plate, and the other end is slidably installed in the third straight slot via a connecting post. One end of the second support rod is hinged to the side wall of the perforated heat dissipation plate, and the other end is slidably installed in the first straight slot via the connecting rod. The first and second support rods are cross-connected to form a scissor-type telescopic frame. An electric push rod electrically connected to the controller is installed on the side wall of the connecting plate, and the piston rod end of the electric push rod is connected to the end of the connecting rod. The bottom end of the dustproof baffle is installed on the connecting rod, and the top end is slidably installed in the second straight slot via a connecting post.

[0007] The perforated heat sink is equipped with dust covers at both the top and bottom.

[0008] The beneficial effects of this utility model are:

[0009] This utility model uses a telescopic mechanism to extend the perforated heat dissipation plate and filter screen out of the heat dissipation vent of the cabinet, while simultaneously moving the dustproof baffle downward to automatically block the heat dissipation vent. Cleaning and maintenance can be carried out without disassembling the filter screen, which is simple to operate, improves work efficiency, and prevents dust generated during the cleaning process from entering the high-voltage outgoing cabinet, thus avoiding safety accidents.

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] This utility model discloses a high-voltage outgoing line cabinet for a substation. The cabinet mainly includes a cabinet body 1, a heat dissipation vent 2, a perforated heat dissipation plate 3, a filter screen 4, a telescopic mechanism 5, a dustproof baffle 6, and a connecting plate 7. The cabinet body 1 has a heat dissipation vent 2 on its side wall. The connecting plate 7 is installed on the side wall of the cabinet body 1 and has a rectangular slot 703 that mates with the heat dissipation vent 2. The perforated heat dissipation plate 3 is installed on the connecting plate 7 via the telescopic mechanism 5, located directly opposite the heat dissipation vent 2. The filter screen 4 is installed on the inner wall of the perforated heat dissipation plate 3. A vertically sliding dustproof baffle 6 is installed on the connecting plate 7, slidingly mounted on the connecting plate 7 and connected to the telescopic mechanism 5. The telescopic mechanism 5 includes a first support rod 501, a second support rod 502, a connecting rod 503, and an electric push rod 504. The connecting plate 7 has a first straight slot 701 and a second straight slot 702 on its side wall, and the mesh heat dissipation plate 3 has a third straight slot 301 on its side wall. One end of the first support rod 501 is hinged to the side wall of the connecting plate 7, and the other end is slidably installed in the third straight slot 301 through the connecting column. One end of the second support rod 502 is hinged to the side wall of the mesh heat dissipation plate 3, and the other end is slidably installed in the first straight slot 701 through the connecting rod 503. The first support rod 501 and the second support rod 502 are cross-connected to form a scissor-type telescopic frame. An electric push rod 504 electrically connected to the controller is installed on the side wall of the connecting plate 7. The piston rod end of the electric push rod 504 is connected to the end of the connecting rod 503. The bottom end of the dustproof baffle 6 is installed on the connecting rod 503, and the top end is slidably installed in the second straight slot 702 through the connecting column.

[0017] When the filter screen 4 needs cleaning, the operator controls the electric push rod 504 to retract via the controller on the cabinet 1. The piston rod of the electric push rod 504 drives the connecting rod 503 to move closer to the electric push rod 504. Since the first support rod 501 and the second support rod 502 are cross-connected to form a scissor-type telescopic frame, the movement of the connecting rod 503 will cause the first support rod 501 and the second support rod 502 to rotate, causing the mesh heat dissipation plate 3 and the filter screen 4 to extend out of the heat dissipation vent 2 on the side wall of the cabinet 1. At the same time, the movement of the connecting rod 503 will also cause the dust baffle 6 to move down, automatically blocking the heat dissipation vent 2 and preventing dust generated during the cleaning process from entering the high-voltage outgoing cabinet. After cleaning is completed, the electric push rod 504 is extended via the controller, causing the mesh heat dissipation plate 3 and the filter screen 4 to retract into the heat dissipation vent 2 of the cabinet 1. At the same time, the dust baffle 6 is moved up, restoring ventilation to the heat dissipation vent 2. Cleaning and maintenance can be performed without disassembling the filter screen, which is simple to operate and improves work efficiency.

[0018] The top and bottom of the perforated heat dissipation plate 3 are equipped with dust covers 8, which can effectively block dust and debris, prevent dust from entering the cabinet 1 from the top and bottom of the perforated heat dissipation plate 3, and thus keep the inside of the cabinet 1 clean.

[0019] Work process:

[0020] When the filter screen 4 needs cleaning, the operator controls the electric push rod 504 to retract via the controller on the cabinet 1. The piston rod of the electric push rod 504 drives the connecting rod 503 to move closer to the electric push rod 504. Since the first support rod and the second support rod are cross-connected to form a scissor-type telescopic frame, the movement of the connecting rod 503 will drive the first support rod 501 and the second support rod 502 to rotate, causing the mesh heat dissipation plate 3 and the filter screen 4 to extend out of the heat dissipation vent 2 on the side wall of the cabinet 1. At the same time, the movement of the connecting rod 503 will also cause the dust baffle 6 to move down, automatically blocking the heat dissipation vent 2 and preventing dust generated during the cleaning process from entering the high-voltage outgoing cabinet. After cleaning is completed, the controller controls the electric push rod to extend, causing the mesh heat dissipation plate 3 and the filter screen 4 to retract into the heat dissipation vent 2 of the cabinet 1. At the same time, the dust baffle 6 moves up, restoring ventilation to the heat dissipation vent 2. Cleaning and maintenance can be performed without disassembling the filter screen, which is simple to operate and improves work efficiency.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
