Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to a circuit breaker maintenance device and electrical cabinet. Background Technology

[0002] Electrical control cabinets are widely used in various industries. These cabinets contain circuit breakers and handle various daily needs. Since electrical control cabinets operate continuously as long as power is supplied, maintenance and repair are crucial for their normal operation, ensuring the safe and stable functioning of all components in the circuit system.

[0003] Currently, electrical control cabinets, especially those used in simulation training, contain a large number of circuit breaker components. When disconnecting and repairing these components, electrical engineers often need to first use tools to remove the screws on the front panel to expose the circuit breaker, then open the side door of the electrical cabinet and move it away from the cabinet. Only through the inspection port located behind the component on the side door can the circuit breaker be inspected and repaired. This operation is cumbersome, requires additional auxiliary tools, and screws and other fasteners are easily lost. This is especially true for multi-row circuit breaker components, making maintenance inconvenient and time-consuming, resulting in low maintenance efficiency. Utility Model Content

[0036] According to a first aspect of the present invention, a circuit breaker maintenance device is provided, which includes a mounting base 10, a protective component 30, and a magnetic component 40.

[0037] The specific structure of the above-described components of the circuit breaker 20 maintenance device according to this embodiment will be described below.

[0038] In this embodiment, as Figure 2 and Figure 3 As shown, the mounting base 10 has a recessed receiving cavity 11 for mounting the circuit breaker 20. The receiving cavity 11 can be a rectangular or cylindrical cavity structure, as long as it can meet the installation requirements of accommodating all the circuit breakers 20. In this embodiment, the mounting base 10 can be a sheet metal part formed by sheet metal processing from a metal plate.

[0039] In this embodiment, as Figures 1 to 3 As shown, the protective member 30 is formed as a plate-like structure and is connected to the mounting base 10 to cover the receiving cavity 11, thereby reducing the area of ​​the opening of the receiving cavity 11 and preventing the circuit breaker 20 in the receiving cavity 11 from being completely exposed. The protective member 30 is provided with an operation port 31, which is a through hole structure that runs through the thickness direction of the protective member 30, so that the operating mechanism 21 on the circuit breaker 20 can extend out. Specifically, the operating mechanism 21 on the circuit breaker 20 can be an operating handle. Moving the operating handle can change the circuit breaker 20 to be in the connected state or the disconnected state. In this embodiment, the operation port 31 can be a through hole of rectangular, circular or elliptical shape, so that the protective member 30 does not need to be disassembled when using the circuit breaker 20, thus meeting the usage requirements of the circuit breaker 20.

[0040] In a preferred embodiment, such as Figures 1 to 3 The opening of the cavity 11 shown is located on the side of the mounting base 10, and the protective component 30 is located on the side wall of the mounting base 10, thus preventing personnel from operating and maintaining the circuit breaker 20.

[0041] Furthermore, in this embodiment, as Figure 2 and Figure 3 As shown, the cavity wall of the receiving cavity 11 is provided with a wiring hole 111 to meet the wiring requirements of the circuit breaker 20. The wiring hole 111 is a through hole structure that penetrates the cavity wall of the receiving cavity 11. One or more wiring holes 111 can be provided according to actual needs. The wiring hole 111 can be a rectangular or circular through hole structure.

[0042] Furthermore, in this embodiment, multiple circuit breakers 20 are provided, and the multiple circuit breakers 20 can be arranged in a linear manner. The protective member 30 is provided with an indicator on the side facing away from the mounting base 10. The indicator is provided in correspondence with the circuit breaker 20 to show the function and / or specifications of the circuit breaker 20, thus intuitively showing the information of different circuit breakers 20.

[0043] In this embodiment, as Figure 3 As shown, the magnetic suction component 40 is disposed between the mounting base 10 and the protective component 30, allowing the protective component 30 and the mounting base 10 to be detachably connected. The magnetic detachable connection method ensures a reliable connection between the protective component 30 and the mounting base 10. When the circuit breaker 20 needs to be repaired, only a little force is required to remove the protective component 30 from the mounting base 10 without the need for disassembly tools. This makes disassembly and assembly convenient, saves time, improves maintenance efficiency, and shortens the downtime of the electrical cabinet. Furthermore, only the protective component 30 needs to be removed from the mounting base 10, without the need for additional screws or other fasteners, which improves disassembly and assembly efficiency while avoiding the loss of fasteners.

[0044] In this embodiment, the magnetic attractor 40 is preferably a magnet capable of attracting ferromagnetic materials. The magnet is a permanent magnet, which has the advantages of simple structure, convenient operation, and low cost. In other alternative embodiments, the magnetic attractor 40 can also be an electromagnet, so that the formation or disappearance of the magnetic field can be achieved by electronic control, thereby completing the magnetic detachable connection between the mounting base 10 and the protective component 30.

[0045] Furthermore, in a preferred embodiment, one of the protective member 30 and the mounting base 10 is formed as a ferromagnetic member that can be attracted by the magnetic member 40. That is, at least one of the protective member 30 and the mounting base 10 is made of a metal material that can be attracted to the magnetic member 40, such as 45 steel. The magnetic member 40 is embedded in the other of the protective member 30 and the mounting base 10, thereby fixing the magnetic member 40.

[0046] In this embodiment, the magnetic suction element 40 is a block structure.

[0047] In one alternative implementation, such as Figure 3 As shown, the mounting base 10 has a groove, and the magnetic component 40 is embedded in the groove. The protective component 30 is a ferromagnetic component. This method of fixing the magnetic component 40 and the mounting base 10 together makes the protective component 30 lighter and facilitates disassembly and assembly of the protective component 30 and the mounting base 10. Optionally, connecting holes can be provided on the magnetic component 40 and the mounting base 10, and the magnetic component 40 can be fixed in the groove by fasteners such as screws or bolts to prevent the magnetic component 40 from falling out of the groove. However, the method of fixing the magnetic component 40 and the mounting base 10 is not limited to this; adhesive or other methods can also be used, as long as the fixation is reliable.

[0048] Furthermore, in a preferred embodiment, such as Figure 3 As shown, multiple magnetic suction components 40 are provided, and the multiple magnetic suction components 40 are arranged circumferentially around the receiving cavity 11. This enhances the overall magnetic suction capability of the magnetic suction components 40, ensuring that the protective component 30 is reliably installed on the mounting base 10 and preventing the protective component 30 from accidentally falling off the mounting base 10.

[0049] Furthermore, in this embodiment, as Figures 1 to 3 As shown, the circuit breaker 20 maintenance device also includes a handle 60. The handle 60 is located on the side of the protective member 30 facing away from the mounting base 10, so that maintenance personnel can easily grasp the handle 60 to apply force and quickly remove the protective member 30 from the mounting base 10. Preferably, there are two handles 60, which are respectively located on both sides of the operating port 31, so that maintenance personnel can easily grasp the handle 60 with both hands, which facilitates the application of force and avoids repeated attraction between the magnetic member 40 and the protective member 30.

[0050] Furthermore, in this embodiment, such as Figures 1 to 3 As shown, the circuit breaker 20 maintenance device also includes a door 50, which is installed inside the electrical cabinet and rotatably connected to the electrical cabinet. Specifically, as shown... Figure 1 As shown, the side of the inner body is provided with a hinge 53, which can be a hinge structure to realize the rotation of the door 50 relative to the electrical cabinet. The mounting base 10 is fixed to the door 50, so that the door 50 can be rotated out of the electrical cabinet for easy maintenance of the circuit breaker 20.

[0051] More specifically, the door body 50 is provided with an inspection port 51. The inspection port 51 can be a through-hole structure of rectangular, circular, or elliptical shape. After the protective member 30 is removed from the mounting base 10, it can be taken out through the inspection port 51 to ensure that the protective member 30 can be easily removed from the mounting base 10. It should be noted that in this embodiment, the operating mechanism 21 can also extend from the inspection port 51 to ensure that the circuit breaker 20 can be easily controlled to be on or off from the outside of the door body 50.

[0052] Furthermore, in this embodiment, as Figures 1 to 3 As shown, a door lock 52 is provided on the door body 50 so that the door body 50 can be fixed to the electrical cabinet. The door lock 52 can be a rotary latch type door lock 52 structure.

[0053] According to the circuit breaker maintenance device of this utility model, the mounting base has a recessed receiving cavity for installing the circuit breaker; the protective member is connected to the mounting base to cover the receiving cavity, and the protective member has an operating port for the operating mechanism on the circuit breaker to extend out, so as not to affect the normal use of the circuit breaker; the magnetic suction member is set between the mounting base and the protective member, so that the protective member and the mounting base form a magnetic detachable connection. The magnetic detachable connection method ensures that the connection between the protective member and the mounting base is reliable. When the circuit breaker needs to be maintained, only a little force is needed to remove the protective member from the mounting base, without the need for disassembly tools, which is convenient and saves time.

[0054] The electrical cabinet provided by this utility model includes the circuit breaker maintenance device as described above, which improves the maintenance efficiency of the circuit breaker, thereby reducing the downtime of the electrical cabinet and ensuring the use requirements and safety of the electrical cabinet.

[0055] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application.
