Description

TECHNICAL FIELD

[0001] The utility model belongs to the grounding detection field, concretely relates to a visual intelligent grounding wire locking device. BACKGROUND

[0002] In the operation process of the power system, it is crucial to ensure the safety of personnel and equipment. Especially when carrying out power-off maintenance work in the substation, the temporary grounding wire as a basic safety measure, its correct use is directly related to the life safety of operating personnel and the intactness of power equipment. However, although the State Grid Corporation has strict regulations on the safe operation of the power system, in the actual operation process, there is still a big technical challenge in "preventing the combination of grounding wire (grounding knife switch) and circuit breaker (isolating switch)".

[0003] At present, due to technical limitations, it is still not possible to realize fully automated or intelligent mandatory anti-electricity misoperation mechanism. Especially in some key links such as the operation process of circuit breaker or isolating switch, if all temporary grounding wires cannot be removed in time, it may cause serious accidents. Therefore, how to effectively avoid the problem that temporary grounding wires are not completely removed before the equipment is put into operation has become a technical problem to be solved.

[0004] Specifically, under the existing technical conditions, there are the following problems:

[0005] Limitations of manual inspection: Before the equipment is put into operation again, all temporary grounding wires need to be manually confirmed one by one. However, this kind of inspection method depending on manpower is easy to miss, especially in complex large-scale substations, due to the large number and wide distribution of grounding wires, once the missing removal occurs, it will bring great safety hazards to the subsequent operation.

[0006] Information acquisition is not timely: when operating the grounding wire, it is difficult for the workers to master the state information of all grounding wires in the entire work area in real time. This delay in information acquisition not only affects the work efficiency, but also increases the possibility of misoperation.

[0007] Lack of effective early warning mechanism: when the grounding wire is missing, the existing system cannot provide immediate alarm signals. This means that problems cannot be found until faults occur or equipment abnormals, which undoubtedly increases the difficulty of handling accidents and may lead to more serious consequences.

[0008] Based on this, the utility model provides a visual intelligent grounding wire locking device. Utility model content

[0010] One end of the grounding wire is connected with the power system, the other end of the grounding wire is connected with the processor, and the processor is used for acquiring the working area information, the connection quantity and the set interval of the grounding wire;

[0011] The processor is connected with the wireless communication module, the wireless communication module is connected with the gateway, and the wireless communication module is used for realizing the communication between the grounding wires;

[0012] The processor is connected with the alarm device, and the alarm device is used for issuing an alarm when the distance between two adjacent grounding wires exceeds the set interval.

[0013] In some preferred embodiments, the processor is connected with a display, and the display is used for displaying the working area information, the connection quantity and the set interval.

[0014] In some preferred embodiments, the processor is connected with a matrix operation device, and the matrix operation device is used for parameter setting of the grounding wire.

[0018] In some preferred embodiments, the matrix operation device is a matrix keyboard.

[0019] In some preferred embodiments, the processor is connected with a battery.

[0020] The utility model has the advantages of:

[0021] Enhance security: by adopting the intelligent grounding wire with wireless communication function, the mutual communication and confirmation function between the grounding wires are realized. In the use process, the grounding wire can be mutually bound, and the distance information between each other can be acquired in real time. In this way, the risk of missing grounding wire caused by human factors can be greatly reduced, and the safety in the process of power maintenance is improved.

[0022] Efficiency: The data visualization function of the intelligent grounding wire allows the inspection personnel to understand the working status of the grounding wire at any time in the work site, including the current working area, the actual number of ground wires, and the number of required ground wires, and other key information. Real-time updating of these information helps workers quickly locate problem points, reduce search time, and improve work efficiency.

[0023] Prevent accidents: The built-in alarm prompt function of the grounding wire can automatically issue an alarm if there is a grounding wire missing after the equipment maintenance is completed. This immediate feedback mechanism can remind workers to handle the undetached grounding wire in time, avoiding equipment short circuit or other serious accidents caused by missing.

[0024] Simplify the operation process: By integrating the matrix keyboard input function, users can directly set the necessary parameters for the intelligent grounding wire on site without relying on additional software or platforms. Such design not only simplifies the operation process, but also improves the convenience and flexibility of device use, further reducing the possibility of operation errors.
