Technical Field

[0001] This utility model relates to the field of circuit breakers, specifically to a grounding cabinet for preventing misoperation. Background Technology

[0002] Switchgear is used during equipment maintenance to prevent electric shock accidents caused by sudden power surges. It ensures the safety of maintenance personnel by grounding both ends of the equipment under maintenance. Simultaneously, switchgear helps to discharge residual charge, improving maintenance safety. Furthermore, it can interrupt fault currents via circuit breakers, thereby quickly restoring power.

[0003] Furthermore, in existing systems, a dedicated grounding cabinet is used to connect with the switchgear, forming a stable grounding point to ensure the operational safety of the switchgear. However, existing grounding cabinets require connection to other switchgear while simultaneously being in a closed state for the grounding operation to be complete. However, if any operation is mistakenly performed during this process, it can easily lead to safety issues for the switchgear operator, posing a potential safety hazard due to human error.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, this embodiment provides a grounding cabinet to prevent misoperation, including a grounding cabinet body 10 and an external switch 20. The grounding cabinet body 10 is provided with a drive unit 101 for closing or opening itself, and an interlocking plate 102 driven by the drive unit 101 to link the closing plate 107 and the grounding rod 108. The external switch 20 includes a main shaft 201 disposed in the grounding cabinet body 10 and a pull rod 202 linked with the main shaft 201 for connecting or disconnecting. A locking plate 2021 located in the grounding cabinet body 10 is disposed on the pull rod 202, and a first locking part 2022 is disposed on the locking plate 2021. A second locking part 1021 is disposed on the interlocking plate 102, and a locking plate 103 is disposed on the grounding cabinet body 10 for locking connection with the first locking part 2022 or the second locking part 1021.

[0035] Specifically, the grounding cabinet body 10 is a three-position switch grounding cabinet structure, and the external switch 20 is also a three-position switch structure. The drive unit 101 can be a motor, which drives the closing plate 107 inside the grounding cabinet body 10 to move, thereby switching between the closed and open states. The interlocking plate 102 moves synchronously under the action of the drive unit 101 to ensure the linkage between the closing plate 107 and the grounding rod 108. The external switch 20 is a vacuum switch with an insulating shell. Inside the insulating shell, there is a moving contact connected to the pull rod 202 and a stationary contact for external connection. The pull rod 202 is connected to the main shaft 201, and the extension and retraction of the pull rod 202 realizes the circuit connection or disconnection.

[0036] During use, the external switch 20 is used to establish an electrical connection with the external switchgear. At this time, the pull rod 202 is in the conductive state, aligning the first locking part 2022 on the locking plate 2021 with the locking plate 103 to secure the locking plate 2021 and the locking plate 103, maintaining the conductive state. Simultaneously, the grounding cabinet body 10 is switched to the closed state via the drive unit 101, causing the interlocking plate 102 to move in tandem. The second locking part 1021 on the interlocking plate 102 aligns with and locks the locking plate 103, ensuring a stable closed state and preventing misoperation. Furthermore, the interlocking plate 102 is linked with the grounding rod 108. When the interlocking plate 102 is locked, the grounding rod 108 is also locked, maintaining the grounding state and ensuring the safety and reliability of the entire grounding cabinet. This prevents safety accidents caused by misoperation and improves operational safety.

[0037] Furthermore, the first locking part 2022 or the second locking part 1021 can be a lock hole. The locking plate 103 is provided with a through hole 1031 that overlaps with or is misaligned with the lock hole, and a lock head that locks the first locking part 2022 and / or the second locking part 1021 to the through hole 1031. The locking connection can be achieved through the lock head, which locks the locking plate 2021 and the interlocking plate 102 onto the locking plate 103. After the locking connection is established, the lock head can effectively prevent the locking plate 2021 and the interlocking plate 102 from accidentally disengaging, ensuring the conduction, closing, or grounding status of the anti-misoperation grounding cabinet and improving operational safety.

[0038] like Figure 3 As shown, in this embodiment, the grounding cabinet body 10 is provided with a cutting power component 104 that drives the main shaft 201 to rotate and cut, and a conducting power component 105 that drives the main shaft 201 to rotate and conduct. The cutting power component 104 and the conducting power component 105 can be springs. The spring force drives the main shaft 201 to rotate, which in turn drives the pull rod 202 to conduct or cut.

[0039] Furthermore, such as Figure 3 As shown, in this embodiment, the conducting power component 105 is an energy storage spring. The grounding cabinet body 10 is equipped with an energy storage motor 106 that drives the energy storage spring to store energy. The energy storage motor 106 can be a servo motor. The energy storage motor 106 is driven by a gear set. An eccentric rod is designed on the gear and connected to one end of the energy storage spring. In this way, the energy storage spring can be driven to store energy so that it has enough elasticity to conduct the operation and ensure the stability of closing.

[0040] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the main shaft 201 is equipped with a first swing arm 2011 connected to the pull rod 202, a second swing arm 2012 connected to the cutting power component 104, and a third swing arm 2013 connected to the conducting power component 105. The design of the swing arm structure allows the pull rod 202 to move linearly, forming a stable conducting or cutting path, ensuring precise operation. Similarly, the design of the second swing arm 2012 and the third swing arm 2013 facilitates the rotation of the main shaft 201 and also makes it easier to connect the conducting power component 105 and the cutting power component 104, improving the coordination of the movements.

[0041] like Figure 2 and Figure 5 As shown, in this embodiment, the interlocking plate 102 is provided with an electronic locking part 1022, and the grounding cabinet body 10 is provided with a locking hole 1023 for locking or unlocking with the electronic locking part 1022. The locking hole 1023 can be an electromagnetic lock or a mechanical lock, which can form a double locking mechanism to ensure a tight connection between the interlocking plate 102 and the locking plate 103 and prevent accidental unlocking.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
