[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] Some high-voltage switch cabinets in the prior art have independent spaces for safety or to facilitate the distinction between different types of electronic components. However, after maintenance and setup, workers sometimes forget to close the cabinet door, which easily causes dust to quickly accumulate inside the cabinet, affecting the service life of the high-voltage switch cabinet.

[0021] In view of this, the utility model provides an independent space self-locking high-voltage switch cabinet, which realizes automatic closing of the cabinet door through the cooperation between the cabinet door, electric hinge, electronic lock, damping sleeve and spring, and when there is manual operation, it is necessary to pull the pull rod at intervals to ensure that the cabinet door will not be closed. Once the maintenance or overhaul operations are completed, the staff forgets to close the cabinet door, and only needs to wait for the pull rod to trigger the switch under the action of the spring, and the electric hinge and electronic lock can be controlled by the controller to complete the automatic closing and locking of the door in turn, thereby reducing dust accumulation and facilitating the heat dissipation and service life of the internal electronic components.

[0022] Depend on Figure 1-4 It can be seen that an independent space self-locking high-voltage switchgear in this case includes a cabinet body 1, the cabinet body 1 is provided with a plurality of partitions 2, a cabinet door 3 is provided on the front of the partition 2, the cabinet door 3 is installed on the front of the cabinet body 1 through an electric hinge 4, a controller 5 and an electronic lock 6 are respectively installed on the cabinet door 3, and an unmanned monitoring structure is provided on the cabinet door 3; the unmanned monitoring structure includes an outer shell 7, a pull rod 8, a damping sleeve 9, a spring 10, a switch 11 and a buckle cover 12; the outer shell 7 is installed on the surface of the cabinet door 3, a pull rod 8 is provided on the inner wall of the outer shell 7, a damping sleeve 9 is installed between the pull rod 8 and the outer shell 7, one end of the pull rod 8 located inside the outer shell 7 is fixedly connected to a spring 10, the end of the spring 10 is fixedly connected to a buckle cover 12, and the buckle cover 12 is installed on the end of the outer shell 7 away from the pull rod 8.

[0023] In the specific implementation process, it is worth pointing out that the cabinet 1 is a high-voltage switch cabinet, and the purpose of setting up several partitions 2 is to independently place different electronic devices. Of course, the independent space self-locking high-voltage switch cabinet can also be used in other fields, and is not completely limited to the direction of high-voltage switch cabinets. However, its original design intention is to solve the problem that the staff forgets to close the door after the high-voltage switch cabinet is repaired or set up. The cabinet door 3 can be automatically closed by the electric hinge 4, and the electronic lock 6 can automatically lock the cabinet door 3. Of course, both are controlled by the controller 5. The specific models of the three can be selected according to actual needs. The shell 7 and the pull rod 8 can form a timing device under the action of the damping sleeve 9 and the spring 10, that is, pull the pull rod 8, At this time, the spring 10 is stretched. After the external force is removed, under the action of the spring 10, the pull rod 8 retracts into the interior of the shell 7. However, due to the presence of the damping sleeve 9, this process is slow. At this time, the staff can perform maintenance operations and pull the pull rod 8 again before the end of the pull rod 8 contacts the switch 11 to stretch the spring 10. In this way, once the personnel leave, the switch 11 is finally triggered and the signal is transmitted to the controller 5. The controller 5 drives the electric hinge 4 to close the cabinet door 3 and starts the electronic lock 6 to lock the cabinet door 3. The time for the pull rod 8 to retract into the shell 7 and trigger the switch 11 can be achieved by changing the elastic coefficient of the spring 10 or changing the damping of the damping sleeve 9. The specific selection and design can be made according to actual needs.

[0024] In one practicable manner, see Figure 3 The buckle cover 12 is snap-fitted to the housing 7 via the snap block 13 .

[0025] In the specific implementation process, it is worth pointing out that such a design does not require the use of screws or the like for fixing, which facilitates the assembly of the buckle cover 12 and the housing 7.

[0026] Furthermore, a handle 14 is fixedly connected to one end of the pull rod 8 located outside the housing 7 .

[0027] In the specific implementation process, it is worth pointing out that the purpose of setting the handle 14 is to facilitate the operator to pull the pull rod 8.

[0028] In one practicable manner, see Figure 1 , Figure 2 and Figure 4 A lever 15 is rotatably connected to the lower front side of the cabinet door 3 .

[0029] In the specific implementation process, it is worth pointing out that the design of the lever 15 can set a controller 5, an electric hinge 4 and other structures on the cabinet door 3 located at the top, and the cabinet doors 3 below are closed by the lever 15 installed on the cabinet door 3 above, which can reduce the use of the controller 5 and the electric hinge 4 and reduce costs.

[0030] Furthermore, a limiting strip 16 fixed to the surface of the cabinet door 3 is provided on one side of the lever 15 .

[0031] In the specific implementation process, it is worth pointing out that when the lever 15 is not needed and only the top door 3 is opened separately, the lever 15 can be rotated and fixed by the limit bar 16, wherein the limit bar 16 can be supported by rubber material.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0033] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
