Description

Technical Field

[0001] The utility model relates to the field of electrical maintenance grounding devices, and in particular to a WiFi intelligent control module for grounding devices. Background Art

[0002] In the operation and maintenance of modern power systems, it is extremely important to ensure the safety of electrical equipment maintenance operations; the correct application of grounding devices plays a key role in protecting life safety and equipment integrity. When electrical equipment needs to be maintained or repaired, pre-installed grounding devices become an indispensable safety technical measure, which aims to effectively prevent unexpected calls or electromagnetic induction caused by adjacent live equipment from suddenly energizing the equipment under maintenance by establishing a low-impedance conductive path, thereby protecting on-site workers from electric shock.

[0003] The traditional grounding device is relatively simple in structure and usually consists of three parts: a grounding clamp, a grounding wire (often made of multi-strand soft copper wire to enhance its flexibility and conductivity), and a grounding terminal. These components work together to achieve a reliable electrical connection between electrical equipment and the earth. However, the existing grounding device system has certain limitations, which are mainly reflected in the following aspects:

[0004] 1. Limitations of status monitoring: After the current grounding device is installed, its actual connection status can only rely on direct inspection and confirmation by on-site personnel. This means that once the grounding wire is correctly installed, its subsequent status changes (such as whether it maintains effective grounding) cannot be remotely monitored in real time, which undoubtedly increases the difficulty and risk of safety management for large or remote power facilities.

[0005] 2. Risk of misoperation: In a complex and tense maintenance environment, the accidental removal of ground wires due to human negligence or other factors often occurs. If such misoperation is not detected immediately, the electrical protection of the maintenance equipment will be immediately released, exposing the equipment to potential risks of live electricity, which seriously threatens the life safety of on-site workers.

[0006] In view of the above limitations, it is particularly urgent to develop an intelligent grounding device or related module components that can monitor the status of the grounding device in real time and issue an alarm immediately when the grounding wire is accidentally removed. Such a device module can integrate sensor technology and remote communication capabilities so that the dispatch center or safety management personnel can remotely monitor the working status of each grounding device and respond to abnormal situations in a timely manner, thereby improving the safety management level of power system maintenance operations and ensuring the safety of personnel and equipment. Utility Model Content

[0007] Based on the current status of the background technology, the utility model proposes a WiFi intelligent control module for the grounding device in order to solve the limitations of the existing grounding device in the installation and removal process.

[0010] Furthermore, it also includes a power supply component; the power supply component is connected to the power conversion circuit through a position switch, and the power supply component is used to provide power input to the power conversion circuit when the contacts of the position switch are closed, and to provide continuous power input to the WiFi control component.

[0011] Preferably, the power supply assembly is powered by a detachable battery and / or a solar panel.

[0012] Specifically, the position switch adopts a passive position switch. When the grounding end of the grounding wire is installed in place, the contacts of the passive position switch are matched and closed.

[0013] Specifically, the output end of the power conversion circuit is connected to the grounding state detection end of the WiFi control component; and a safety isolation relay is also provided between the connection between the power conversion circuit and the WiFi control component.

[0014] Preferably, the WiFi control component has a built-in ground wire identity information memory; the ground wire identity information memory stores information on electrical equipment and grounding devices corresponding to the current installation point of the module.

[0015] Furthermore, it also includes an electromagnetic lock; the electromagnetic lock is arranged at the grounding end of the grounding wire, and the electromagnetic lock is used to lock the installation state of the grounding end; the electromagnetic lock is connected to the WiFi control component.

[0016] Preferably, the electromagnetic lock is equipped with a manual bypass actuator; the manual bypass actuator is used to manually change the locking state of the electromagnetic lock.

[0017] In summary, the WiFi intelligent control module proposed in this utility model improves the management and monitoring of grounding devices in power systems, significantly improving the intelligent level of safe operations. The module integrates microelectronics technology and wireless communication technology, and its core advantages and beneficial effects are summarized as follows:

[0018] 1. Real-time remote monitoring and early warning: Through the integrated programmable WiFi chip, the utility model can automatically crawl and analyze the real-time connection status of the grounding terminal of the grounding wire, and realize uninterrupted tracking and remote monitoring of the grounding wire status. Once it is detected that the grounding wire is accidentally removed or the status is abnormal, the early warning signal can be triggered immediately, effectively preventing safety accidents caused by failure of grounding protection, and greatly enhancing the safety protection capability of the work site.

[0019] 2. Intelligent management and efficiency improvement: The WiFi intelligent control module of this utility model can not only count and analyze the use of ground wires in real time, but also identify the identity information of ground wires, providing accurate data support for operation and maintenance management. This can save a lot of manpower and material resources for routine status inspections, and also significantly improve work efficiency and shorten fault response time.

[0022] Figure 1 This is a schematic diagram of the structural connection of the WiFi intelligent control module of the utility model. DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1 As shown, a WiFi intelligent control module for a grounding device is installed on the grounding device set at the grounding point of the electrical equipment; it includes a position switch, a power conversion circuit and a WiFi control component connected in sequence; the position switch is set on the grounding wire of the grounding device, and the signal state of the position switch matches the installation state of the grounding end of the grounding wire; the WiFi control component is communicated and connected to a remote operation and maintenance monitoring center.

[0027] In this embodiment, Figure 1 As shown, the module also includes a power supply component; the power supply component is connected to the power conversion circuit through a position switch, and the power supply component is used to provide power input to the power conversion circuit when the contacts of the position switch are closed, and to provide continuous power input to the WiFi control component.

[0028] The power supply component is powered by a removable battery and / or solar panel. This configuration can improve the independence and endurance of the module, thereby ensuring that the module can still work normally for a long time without an external power supply.

[0029] In this embodiment, the position switch adopts a passive position switch. When the grounding end of the grounding wire is installed in place, the contacts of the passive position switch are matched and closed. The role of the position switch in the module is mainly to detect whether the grounding wire has been correctly installed or removed, so its function is realized by the passive position switch. As a passive device, it can work without relying on an external power supply, including common mechanical micro switches, proximity switches and Hall effect switches, etc., which can be used to sense state changes and turn on the power conversion circuit to transmit electrical signals.

[0030] The passive position switch in the module of this embodiment is designed to close or open the circuit through physical contact, thereby triggering a signal; it not only simplifies the circuit and reduces power consumption, but also improves the reliability and safety of the normal operation of the module. Passive devices have a lower failure rate than active devices and are not easily affected by electromagnetic interference.

[0031] In this embodiment, the output end of the power conversion circuit is connected to the grounding state detection end of the WiFi control component; a safety isolation relay is also provided between the connection of the power conversion circuit and the WiFi control component. The WiFi control component determines the installation state of the grounding end by enabling the signal of its grounding state detection end; the provision of the safety isolation relay here can achieve complete electrical isolation, enhance the safety of signal transmission in the module, and prevent high voltage or abnormal current from damaging the WiFi control component.

[0032] In this embodiment, the WiFi control component has a built-in ground wire identity information memory; the ground wire identity information memory stores information about the electrical equipment and grounding device corresponding to the current installation point of the module.

[0033] In this embodiment, Figure 1 As shown, the module also includes an electromagnetic lock; the electromagnetic lock is set at the grounding end of the grounding wire, and the electromagnetic lock is used to lock the installation state of the grounding end; the electromagnetic lock is connected to the WiFi control component. The electromagnetic lock is equipped with a manual bypass actuator; the manual bypass actuator is used to manually change the locking state of the electromagnetic lock. The use of the electromagnetic lock adds an additional reliable grounding safety layer for the grounding device to prevent electrical safety accidents caused by misoperation or unauthorized access.

[0034] In addition, a variety of environmental monitoring sensors can be configured at the grounding point of the electrical equipment, integrating components such as humidity and temperature sensors to monitor the environmental conditions of the grounding point in real time, and they can also be connected to the WiFi control component; when the environmental conditions exceed the preset safety range, the WiFi control component will alert the remote operation and maintenance monitoring center.

[0035] At the same time, the corresponding components in the module can also be equipped with a variety of status indicators, which are used to remind on-site operators of the current component status, including power status, grounding connection status, and WiFi connection status. For example, a green light indicates that the power is normal, a flashing blue light indicates that the WiFi is connected, a red light indicates that the grounding wire is correctly connected, and a flashing yellow light indicates that the grounding wire is waiting for connection or removal confirmation, which enhances intuitiveness. This type of configuration can intuitively and effectively improve the operation and maintenance experience of on-site operators.

[0036] Example 2

[0037] Based on Example 1, this example introduces a WiFi intelligent control method for a grounding device. This method requires installing the WiFi intelligent control module in Example 1 on the grounding device of the electrical equipment. When the electrical equipment needs to be operated or repaired, the following steps are used to complete the installation, status monitoring and control of the grounding wire:

[0038] S11, turn on the power switch of the power supply component itself, and the WiFi control component and the electromagnetic lock are powered on and enter the operating state;

[0039] S12, the remote operation and maintenance monitoring center receives the report of the WiFi control component on the information stored in the ground wire identity information storage device, and controls the electromagnetic lock to be in a released state through the WiFi control component;

[0040] S13. The on-site operator installs the grounding end of the grounding wire, triggers the position switch, and the contacts of the position switch close;

[0041] S14, when the position switch is closed, the power conversion circuit receives the electric energy input and converts it into a corresponding electric signal, which is output to the grounding state detection terminal of the WiFi control component;

[0042] S15, after the WiFi control component confirms that the signal of its grounding status detection terminal is enabled, it continuously reports the grounding connection information to the remote operation and maintenance monitoring center, and the remote operation and maintenance monitoring center presents the "ground connection" status information to the outside;

[0043] S16. After the remote operation and maintenance monitoring center confirms that the grounding end of the grounding wire has been installed, the electromagnetic lock is controlled to be in a locked state through the WiFi control component to lock the installation state of the grounding end; finally, the wire clamp of the grounding wire is installed on the electrical equipment to complete the installation of the grounding wire.

[0044] Accordingly, after the operation and maintenance or overhaul of the electrical equipment is completed, the following steps are used to complete the removal, status monitoring and control of the grounding wire:

[0045] S21. The on-site operator reports the completion of operation and maintenance or overhaul to the remote operation and maintenance monitoring center, and removes the wire clamp of the ground wire installed on the electrical equipment;

[0046] S22, the remote operation and maintenance monitoring center controls the electromagnetic lock to be in a released state through the WiFi control component;

[0047] S23, the on-site operator removes the grounding end of the grounding wire, and the contacts of the position switch are disconnected accordingly;

[0048] S24, the power conversion circuit loses power input, the WiFi control component confirms that its grounding state detection terminal has no enable input, and continuously reports grounding disconnection information to the remote operation and maintenance monitoring center, and the remote operation and maintenance monitoring center presents "ground wire disconnection" status information to the outside;

[0049] S25. Turn off the power switch of the power supply assembly itself, stop the WiFi intelligent control module, store the grounding wire and its accessories, and complete the removal of the grounding wire.

[0050] In this embodiment, for reporting of ground connection information and ground disconnection information, the remote operation and maintenance monitoring center can preset a delay time of a certain scale to prevent false alarms caused by interference fluctuations of ground line installation and removal signals.

[0051] At the same time, once the installation of the grounding wire is confirmed to be completed, when the on-site operators begin to operate or repair the corresponding electrical equipment, when the remote operation and maintenance monitoring center has not received the completion information reported by the on-site operators, but finds that the "ground wire is disconnected" status information appears, it can promptly issue an alarm to the on-site operators that the grounding terminal was mistakenly removed and take corresponding measures. This is the key to improving the safety of electrical equipment maintenance.

[0052] In summary, the WiFi intelligent control module and method of the utility model introduces a new intelligent and networked mode for the management of grounding devices in power systems, fundamentally solves the problem of blind spots in grounding wire monitoring, realizes remote visual management of grounding status and real-time abnormal warning, greatly improves the safety and operation and maintenance efficiency of power facility maintenance operations, and represents an important advancement in the field of power safety technology.
