Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, specifically a high-voltage switchgear that is easy to maintain and repair. Background Technology

[0002] High-voltage switchgear typically uses a metal enclosure, and the interior is divided into multiple independent compartments: circuit breaker compartment, busbar compartment, cable compartment, instrument compartment, etc., with each compartment separated by metal partitions. This provides mechanical support and protection for the line components. Currently used high-voltage switchgear can be broadly classified into fixed type and truck type, the latter facilitating maintenance and circuit breaker replacement.

[0003] Fixed switchgear, with its circuit breakers, disconnectors, and other components fixedly installed within the cabinet, has the advantages of simple structure and low cost. However, it is more limited by space during maintenance and repair and is less flexible.

[0004] A search revealed a high-voltage switchgear for easy inspection and maintenance in patent application number CN209993883U3. The switchgear includes a cabinet and a door. The bottom plate and top plate each have parallel sealing grooves along their edges. A first side plate, a second side plate, and a door are installed between the top plate and the bottom plate. The edge of the first side plate is rotatably connected to the door via a rotating component. The door includes a third side plate, a fourth side plate, and a sealing strip. The first side door is connected to the fourth side plate via a rotating component, and the fourth side plate is connected to the third side plate via a rotating component. Horizontal sealing strips are fixedly connected to the inner edges of the third and fourth side plates.

[0005] This high-voltage switchgear uses a hinged design for two adjacent cabinet doors. By installing rubber strips on the inner cavity frame of the cabinet, the doors can be unlocked and positioned by interlocking the rubber strips and rotating the handle. This allows the high-voltage switchgear to be opened from both sides, improving the efficiency of inspection and maintenance.

[0006] However, when resetting two hinged cabinet doors after opening, one side of the cabinet door needs to be inserted into the glue groove before the other side is inserted into the glue groove. This causes the second door to occupy a large amount of space on the right side during the hinge rotation process, making the usage environment more limited. Utility Model Content

[0007] The purpose of this utility model is to provide a high-voltage switchgear that is easy to maintain and repair. By improving the side door design of the high-voltage switchgear, the fixed high-voltage switchgear can not only open and close two side doors instantly, but also reduce the area occupied during the opening and closing process, thus providing more installation opportunities for this type of high-voltage switchgear.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage switchgear that is easy to maintain and repair, comprising a cabinet body, a first cabinet door hinged to one side of the cabinet body, a second cabinet door and a sliding structure for sliding connection between the second cabinet door and the cabinet body on the other side of the cabinet body, a sliding transition rotation structure provided at the adjacent side of the first cabinet door and the second cabinet door, and a positioning structure for positioning the first cabinet door and the second cabinet door on the top of the cabinet body;

A slider is welded to one end of the connecting block, and the slider is welded to the second cabinet door. A cylindrical hole for inserting the temporary rotating shaft is opened in the middle of the connecting block. An elastic structure for driving the temporary rotating shaft to move longitudinally is provided on one side of the first cabinet door.

[0010] Preferably, the elastic structure includes a spring, a cavity is provided inside the first cabinet door, an integrally formed limiting block is provided on the outer wall of the temporary rotating shaft, the limiting block is slidably connected in the cavity, the spring is sleeved on the outer wall of the temporary rotating shaft, the spring is located in the cavity, a rectangular groove is provided on one side of the first cabinet door, the top end of the temporary rotating shaft passes through the first cabinet door, and the bottom end of the temporary rotating shaft is located in the rectangular groove.

[0011] Preferably, the bottom end of the temporary rotating shaft is circular, and the outer edge of the top of the cylindrical hole is arc-shaped.

[0012] Preferably, the sliding structure includes a slide groove for the slider to move within the second cabinet. The slide groove is located on one side of the cabinet, and its cross-section is T-shaped. One end of the slide groove is connected to a rectangular groove.

[0013] Preferably, a handle is welded to one side of the second cabinet door, and the outer wall of the cabinet is provided with heat dissipation grooves and mounting grooves for fixing the cooling fan.

[0014] Preferably, the positioning structure includes a fixing block, which is welded to the cabinet body. Both sides of the fixing block are provided with L-shaped claws, and one end of the L-shaped claw is rotatably connected to the fixing block through a damping shaft.

[0028] The sliding transition rotating structure 5 is located on the adjacent side of the two cabinet doors, including a connecting block 501, a slider 503, a temporary rotating shaft 502 and an elastic structure 7, so as to realize the linkage between the second cabinet door 3 and the first cabinet door 2 after sliding.

[0029] The sliding transition rotation structure 5 includes a connecting block 501 and a temporary rotating shaft 502. A slider 503 is welded to one end of the connecting block 501. The slider 503 is welded to the second cabinet door 3. A cylindrical hole 504 for the temporary rotating shaft 502 to be inserted is opened in the middle of the connecting block 501. An elastic structure 7 for driving the temporary rotating shaft 502 to move longitudinally is provided on one side of the first cabinet door 2.

[0030] By setting up the elastic structure 7, when the second cabinet door 3 is about to detach from the cabinet body 1, the first cabinet door 2 and the second cabinet door 3 become a rotating connection. When the second cabinet door 3 is pulled again, the first cabinet door 2 is driven to open, thus achieving linkage.

[0031] The elastic structure 7 includes a spring 701. A cavity 702 is formed inside the first cabinet door 2. An integrally formed limiting block 703 is provided on the outer wall of the temporary rotating shaft 502. The limiting block 703 is slidably connected within the cavity 702. The spring 701 is sleeved on the outer wall of the temporary rotating shaft 502 and is located within the cavity 702. A rectangular groove 705 is formed on one side of the first cabinet door 2. The top end of the temporary rotating shaft 502 penetrates through the first cabinet door 2, and the bottom end of the temporary rotating shaft 502 is located within the rectangular groove 705. The elastic structure 7 is configured as a spring 701, which allows the temporary rotating shaft 502 to move up and down using the elasticity of the spring 701.

[0032] The bottom end of the temporary rotating shaft 502 is circular, and the outer edge of the top of the cylindrical hole 504 is arc-shaped.

[0033] The sliding structure 4 includes a slide groove 706 for the slider 503 to move within the second cabinet 1. The slide groove 706 is located on one side of the cabinet 1, and the cross-section of the slide groove 706 is T-shaped. One end of the slide groove 706 is connected to a rectangular groove 705.

[0034] The T-shaped slide 706 guides the second cabinet door 3 to slide, reducing the lateral space occupied.

[0035] A handle 8 is welded to one side of the second cabinet door 3, and a heat dissipation groove 10 and a mounting groove 9 for fixing the heat dissipation fan are provided on the outer wall of the cabinet body 1.

[0036] The positioning structure 6 includes a fixing block 601, which is welded to the cabinet 1. Both sides of the fixing block 601 are provided with L-shaped claws 602, and one end of the L-shaped claws 602 is rotatably connected to the fixing block 601 through a damping shaft.

One end of the safety knob 603 is threaded to one side of the second cabinet door 3. A screw hole 604 for threaded connection of the safety knob 603 is provided on one side of the cabinet body 1.

[0039] In use, unscrew the safety knob 603, manually rotate the L-shaped claw 602, and pull the handle 8 to move the connecting block 501 and the slider 503. The slider 503 is located in the slide groove 706. When the slider 503 moves into the rectangular groove 705, the outer edge of the cylindrical hole 504 contacts the temporary rotating shaft 502. Since the outer edge of the cylindrical hole 504 is set to be arc-shaped and the bottom of the temporary rotating shaft 502 is round, the temporary rotating shaft 502 is forced to move upward and compress the spring 701. When the cylindrical hole 504 moves just below the temporary rotating shaft 502, the temporary rotating shaft 502 enters the cylindrical hole 504 under the reset action of the spring 701. At this time, the connection between the first cabinet door 2 and the second cabinet door 3 is a rotating connection. The temporary rotating shaft 502 is inserted into the cylindrical hole 504, and the second cabinet door 3 is separated from the cabinet body 1. At this time, continuing to pull the second cabinet door 3 will drive the first cabinet door 2 to open in conjunction.

[0040] Compared to the traditional direct hinged connection method, this device does not occupy the lateral space on the right side of the cabinet 1 when the second cabinet door 3 is opened or closed, making it suitable for narrower installation environments.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
