[0002] The main function of switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes of a power system. The main components within switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices.

[0003] Currently, when inspecting and repairing internal components and circuit breakers in switchgear, it is necessary to remove and transport the circuit breakers from inside the switchgear, which is quite troublesome. Utility Model Content

[0004] To facilitate user maintenance of the switchgear, this application provides a switchgear that is easy to maintain.

[0005] The switchgear provided in this application, which is easy to maintain, adopts the following technical solution:

[0006] A switch cabinet that is easy to maintain includes a cabinet, a circuit breaker connected to the cabinet, a support mechanism connected to the cabinet, and a support plate located inside the cabinet. The support plate is fixedly connected to the support mechanism, and the support mechanism drives the support plate to move in a direction close to or away from the center of the cabinet. The circuit breaker is detachably and fixedly connected to the top of the support plate.

[0007] By adopting the above technical solution, when users are inspecting and maintaining components such as switch cabinets and circuit breakers, they can control the support mechanism to slide the circuit breaker out of the switch cabinet, providing space for maintenance and enabling users to achieve their maintenance objectives. This also facilitates the maintenance of the switch cabinet.

[0008] Optionally, the support mechanism includes a sliding component connected to the cabinet and a rotating component connected to the sliding component. The sliding component drives the rotating component to move in a direction close to or away from the center of the cabinet. The support plate is fixedly connected to the rotating component, and the rotating component drives the support plate to rotate.

[0009] By adopting the above technical solution, the sliding component drives the rotating component and the circuit breaker to slide out from inside the cabinet, providing space for user maintenance and facilitating user maintenance of the switch cabinet and its internal components. At the same time, when the user starts the rotating component, the rotating component drives the circuit breaker to rotate, allowing the circuit breaker to be presented to the user from multiple angles. The user can then perform maintenance on the circuit breaker from multiple angles without having to move the circuit breaker out of the cabinet for maintenance, making it convenient for the user to maintain the circuit breaker.

[0010] Optionally, the cabinet is provided with a support rod, the bottom end of which is hinged to the surface of the cabinet. The top end of the support rod, away from its hinged end, moves in an arc along a direction that approaches or moves away from the surface of the cabinet. The support rod is detachably and fixedly connected to the bottom of the sliding assembly.

[0011] By adopting the above technical solution, after the sliding assembly brings the rotating assembly and circuit breaker out of the cabinet, they are fixed to the bottom of the sliding assembly by the support rod, which supports the sliding assembly and improves the safety of maintenance work.

[0012] Optionally, the support rod includes a hinge rod hinged to the cabinet and an extension rod connected to the hinge rod. The extension rod is slidably connected to the hinge rod along the length direction of the hinge rod. The extension rod is detachably and fixedly connected to the surface of the hinge rod.

The sliding plate is fixedly located between the two guide rods. The extension rod is detachably connected to the bottom surface of the sliding plate. The rotating assembly is connected to the sliding plate.

[0015] By adopting the above technical solution, when the user is inspecting the switchgear, pulling the sliding plate allows it to be stably pulled out of the cabinet under the limit of the track and guide rod. At the same time, the circuit breaker is also pulled out of the cabinet. Meanwhile, the extension rod supports the sliding plate, making it convenient for the user to carry out maintenance.

[0016] Optionally, the rotating assembly includes a rotating motor fixedly connected to the sliding plate and a rotating plate rotatably connected to the rotating plate. The output end of the rotating motor is fixedly connected to the center of the rotating plate, and the support plate is fixedly connected to the upper surface of the rotating plate.

[0017] By adopting the above technical solution, when the user starts the rotating motor, the rotating motor drives the rotating plate and the circuit breaker to rotate, so that multiple angles of the circuit breaker can be displayed in front of the user, without the need to move the circuit breaker, which makes it convenient for the user to inspect and maintain the circuit breaker.

[0018] Optionally, the bottom surface of the sliding plate is provided with a plurality of threaded holes, which are evenly arranged on the sliding plate along the sliding direction of the sliding plate. The extension rod is provided with a connecting part and a connecting bolt. The connecting part is hinged to the end of the extension rod. The threaded holes are located above the connecting part. The surface of the connecting part is provided with at least two connecting holes. One of the connecting holes is close to the hinge position of the connecting part itself. The connecting bolt passes through the connecting hole and is threaded into the threaded hole.

[0019] By adopting the above technical solution, the connecting part can achieve the purpose of fixing multiple positions on the bottom of the sliding plate, and the connecting bolts realize the stable connection between the connecting part and the sliding plate, which facilitates user maintenance and improves maintenance safety.

[0020] Optionally, the sliding plate is provided with connecting holes on both sides and with support rods on both sides.

[0021] By adopting the above technical solution, both sides of the sliding plate can be supported, so that the sliding plate can be stably fixed, improving the safety of user maintenance.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] When users in this application are inspecting and maintaining components such as the switch cabinet and circuit breakers, they can slide the circuit breaker out of the switch cabinet by controlling the support mechanism to provide space for inspection and maintenance, so that users can achieve their inspection and maintenance purposes and facilitate the inspection and maintenance of the switch cabinet.

[0024] In this application, when the user needs to inspect and maintain components such as the inside of the switch cabinet and circuit breakers, the sliding extension rod is fixed downwards to the sliding assembly. By changing the overall length of the support rod, the sliding assembly can be fixed at multiple positions, making it convenient for the user to adjust the length of the sliding assembly extending out of the cabinet. This facilitates maintenance. The connection part can also be used to fix the bottom of the sliding plate at multiple positions. At the same time, the connecting bolts ensure a stable connection between the connection part and the sliding plate, making maintenance easier and safer. Attached Figure Description
