Description

Technical Field

[0001] This utility model relates to the technical field of grounding switches for high and low voltage power distribution, specifically a grounding switch for high and low voltage power distribution with closing protection function. Background Technology

[0002] Grounding switches for high and low voltage power distribution are switching devices used for grounding operations in electrical systems. When equipment needs maintenance or repair, the grounding switch can ground the circuit, allowing residual charge on the equipment to be quickly discharged, preventing electric shock hazards to maintenance personnel caused by charged equipment. It also prevents equipment from becoming energized due to accidental closing, providing safety assurance for maintenance work. However, existing grounding switches for high and low voltage power distribution have some shortcomings, such as:

[0003] Application No.: CN202323010541.6 describes a protective grounding switch. This device addresses the issue of excessive operating space occupied by grounding switches during opening and closing processes by incorporating a moving contact, grounding wire, hinge plate one, hinge plate two, and circular column. While the number of components in power systems is increasing, reducing the space occupied by grounding switches is a significant improvement. However, in actual use, leakage may occur when the inductive contact structure separates from the grounding base during closing, potentially reducing the safety of the device during operation.

[0004] Therefore, we propose a grounding switch for high and low voltage power distribution with closing protection function to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a grounding switch for high and low voltage power distribution with closing protection function, so as to solve the problem of leakage current in the grounding switches on the market when closing or opening, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grounding switch for high and low voltage power distribution with closing protection function, comprising a device body and a switch body disposed inside the device body, wherein a terminal block is disposed inside the device body, and a grounding base is connected to the bottom of the terminal block;

[0007] The top of the grounding base is connected to the closing mechanism, which includes a relay. The front end of the relay is connected to an inductive contact. The bottom of the inductive contact is connected to a rotating rod, and a conduit is installed in the middle of the rotating rod. A rotating shaft is rotatably connected to the bottom of the rotating rod. A sliding groove is slidably connected to the outside of the rotating shaft. A rotating frame is connected to the outside of the rotating shaft, and a drive shaft is slidably connected to the middle of the rotating frame. The drive shaft can drive the rotating frame to rotate.

[0008] The rotating frame is driven by the drive rod, which allows the rotating shaft to move within the slide groove of the slide platform. This allows the rotating rod and the inductive contact to separate or connect with the grounding base, thus enabling better closing of the circuit breaker. Furthermore, the design of the rotating frame, rotating shaft, and rotating rod ensures that there will be no leakage current conduction when the user manually or through other equipment drives the drive shaft, thereby increasing the stability and safety of the device in actual use.

[0009] As a preferred technical solution of this utility model, the front end of the device body is provided with a closed door, and the closed door is connected to the device body through a hinge. Furthermore, a connecting frame is provided inside the device body, and the connecting frame is fixedly connected to the terminal block.

[0010] The above technical solution enables the device to be more stable when providing protection, thereby increasing the stability of the device during operation.

[0011] As a preferred technical solution of this utility model, the bottom of the main body of the device is provided with a threaded shaft, and an insulating isolation plate is provided on the outside of the threaded shaft. The insulating isolation plate is slidably connected to the threaded shaft. The bottom of the insulating isolation plate is provided with an insulating protective layer, and the insulating protective layer can fit against the top of the grounding base.

[0012] By adopting the above technical solution, by setting an insulating isolation plate and an insulating protective layer inside the main body of the device, the grounding seat can be protected by the insulating isolation plate and the insulating protective layer when the switch is closed, thereby increasing the protection of the device when the switch is closed.

[0013] As a preferred technical solution of this utility model, the main body of the device is provided with a sliding shaft, and the left end of the insulating isolation plate is slidably connected to the sliding shaft. The sliding platform is provided with a sliding groove, and the sliding platform can slide and fit against the left and right sides of the rotating shaft through the sliding groove.

[0014] The above technical solution enables the rotating shaft to be more stable when driving the rotating rod to move, thereby increasing the stability of the device during closing operation.

[0015] As a preferred technical solution of this utility model, the bottom of the relay is attached to the grounding seat, and the bottom of the grounding seat is provided with an insulating frame, and the insulating frame is insulated and fixedly connected to the bottom of the device body.

[0016] The above technical solution enables the bottom of the grounding base to be protected by an insulating frame, thereby increasing the protective performance of the equipment during operation.

[0017] As a preferred technical solution of this utility model, the main body of the device is slidably connected to the drive shaft through a bearing seat, and a spring shaft is provided at the right end of the drive shaft, and the spring shaft is fixedly connected to the main body of the device through the bearing seat.

[0018] The above technical solution enables the main body of the device to be more stable when fixing the drive shaft and the spring shaft, thereby increasing the stability of the equipment during operation.

[0019] As a preferred technical solution of this utility model, a locking rod is provided on the outer side of the drive shaft, and a locking groove is provided in the middle of the rotating frame. When the drive shaft moves to the right, the locking rod can be aligned with the locking groove, thereby causing the drive shaft to drive the rotating frame to rotate.

[0020] The above technical solution enables the drive shaft to rotate the rotating frame when the lever is connected to the slot, and the drive shaft to limit the rotation frame when the lever is separated from the slot, thereby increasing the stability of the equipment during operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by driving the rotating frame to rotate through the drive rod, the rotating shaft can move in the slide groove inside the slide table, thereby separating or connecting the rotating rod and the inductive contact with the grounding seat, thus enabling better closing of the circuit breaker. Furthermore, the arrangement of the rotating frame, rotating shaft and rotating rod ensures that there will be no leakage current conduction problem when the user manually or through other equipment drives the drive shaft, thereby increasing the stability and safety of the device in actual use.

[0022] Furthermore, by installing an insulating isolation plate and an insulating protective layer inside the main body of the device, the grounding seat can be protected by the insulating isolation plate and the insulating protective layer when the switch is closed, thereby increasing the protection of the device when the switch is closed.

[0023] Furthermore, by designing the lever and slot, the drive shaft can rotate the rotating frame when the lever is connected to the slot, and the drive shaft can limit the rotation of the rotating frame when the lever is separated from the slot, thereby increasing the stability of the equipment during operation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] To address the problem of leakage current protection failing when the grounding base 11 is closed in the existing technology, the following solution is disclosed. Please refer to [link / reference]. Figures 1-7 This utility model provides a technical solution: a grounding switch for high and low voltage power distribution with closing protection function, including a device body 1 and a switch body 3 disposed inside the device body 1. The device body 1 is provided with a terminal block 5 inside, and the bottom of the terminal block 5 is connected to a grounding base 11.

[0034] The top of the grounding base 11 is connected to the closing mechanism, and the closing mechanism includes a relay 12. The front end of the relay 12 is connected to an inductive contact 13. The bottom of the inductive contact 13 is connected to a rotating rod 14. A wire conduit 15 is installed in the middle of the rotating rod 14. A rotating shaft 16 is rotatably connected to the bottom of the rotating rod 14. A sliding groove platform 17 is slidably connected to the outside of the rotating shaft 16. A rotating frame 18 is connected to the outside of the rotating shaft 16. A drive shaft 19 is slidably connected to the middle of the rotating frame 18. The drive shaft 19 can drive the rotating frame 18 to rotate.

[0035] The device body 1 has a closed door 2 at the front end, and the closed door 2 is connected to the device body 1 by a hinge. The device body 1 also has a connecting frame 4 inside, which is fixedly connected to the terminal block 5. The device body 1 has a threaded shaft 6 at the bottom, and an insulating isolation plate 8 is provided on the outside of the threaded shaft 6. The insulating isolation plate 8 is slidably connected to the threaded shaft 6. The insulating isolation plate 8 has an insulating protective layer 9 at the bottom, and the insulating protective layer 9 can fit against the top of the grounding base 11.

[0036] The main body 1 of the device is provided with a sliding shaft 7 inside, and the left end of the insulating isolation plate 8 is slidably connected to the sliding shaft 7. The sliding groove platform 17 is provided with a sliding groove inside, and the sliding groove platform 17 can slide and fit against the left and right sides of the rotating shaft 16 through the sliding groove.

[0037] The bottom of the relay 12 is in contact with the grounding base 11, and the bottom of the grounding base 11 is provided with an insulating frame 10. The insulating frame 10 is insulated and fixedly connected to the bottom of the device body 1. The device body 1 is slidably connected to the drive shaft 19 through a bearing seat. The right end of the drive shaft 19 is provided with a spring shaft 20, and the spring shaft 20 is fixedly connected to the device body 1 through a bearing seat.

[0038] A locking rod 21 is provided on the outer side of the drive shaft 19, and a locking groove 22 is provided in the middle of the rotating frame 18. When the drive shaft 19 moves to the right, the locking rod 21 can be aligned with the locking groove 22, thereby causing the drive shaft 19 to drive the rotating frame 18 to rotate.

[0039] Working principle: When using this high and low voltage power distribution grounding switch with closing protection function, the switch body 3 is first installed inside the device body 1, so that the switch body 3 is connected to the grounding seat 11 through the terminal block 5. Then, it can be connected to the grounding seat 11 through the closing mechanism to guide the grounding. That is, the drive shaft 19 moves to the right and is fixedly attached to the rotating frame 18, so that the drive shaft 19 drives the rotating frame 18 to rotate, which in turn drives the rotating shaft 16 to rotate. At the same time, the rotating shaft 16 is also limited by the slide groove inside the slide table 17, so that the rotating shaft 16 slides along the slide groove inside the slide table 17. When the rotating shaft 16 moves, it also drives the bottom of the rotating rod 14 to rotate, which causes the rotating rod 14 to change the position of the conductor 15, the inductive contact 13 and the relay 12, so that the relay 12 and the inductive contact 13 are connected or disconnected from the top of the grounding seat 11.

[0040] When the drive shaft 19 moves to the right, the locking rod 21 on the outside of the drive shaft 19 will engage with the locking groove 22 inside the rotating frame 18, thereby enabling the drive shaft 19 to drive the rotating frame 18 to rotate. When the drive shaft 19 is released, the drive shaft 19 will be pushed by the spring shaft 20, causing the locking rod 21 to disconnect from the locking groove 22, so that the drive shaft 19 can only limit the rotation frame 18. After the grounding seat 11 is connected to the closing mechanism, the threaded shaft 6 can drive the insulating isolation plate 8 to descend, so that the insulating protective layer 9 at the bottom of the insulating isolation plate 8 can fit against the grounding seat 11 for protection.

[0041] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
