Description

Technical Field

[0001] The utility model relates to the field of electrical maintenance grounding devices, in particular to an intelligent grounding device integrating mis-disassembly prevention and remote monitoring. Background Art

[0002] In the operation and maintenance of modern power systems, ensuring operational safety is of vital importance, especially during power outages for electrical equipment maintenance. In order to effectively prevent accidental power transmission or equipment electrification caused by electromagnetic induction, thereby avoiding harm to on-site operators, the installation of grounding wires has become an indispensable safety technical link. Existing grounding devices are mainly composed of basic components such as grounding wire clamps, grounding wire bodies, and grounding terminals. These components work together to form a reliable electrical connection to guide possible currents directly into the ground rather than through the human body.

[0003] However, although the existing grounding devices play a role in basic protection functions, they still expose several defects and safety hazards in actual applications, which urgently need to be solved by technological innovation. First of all, the existing grounding devices generally lack an effective installation and removal locking mechanism. This means that without specific authority control, on-site personnel who are not related to the current operation and maintenance tasks can easily install or remove the grounding wire connection at any time by rotating the nut of the grounding point. This unlimited operating authority undoubtedly increases the risk of misoperation, which may lead to the incorrect connection or disconnection of grounding protection at an inappropriate time, endangering the safety of on-site operators and equipment property.

[0004] Secondly, the existing technology lacks the function of grounding wire status monitoring, especially the remote real-time monitoring capability. Since the working status of the grounding wire cannot be visually confirmed from a distance (remote operation and maintenance monitoring center), on-site operators cannot receive early warning communications and find it difficult to immediately detect any changes in the grounding status. This not only affects the speed of fault response, but may also bury serious accident risks due to failure to detect grounding failure in time.

[0005] Furthermore, regarding the correct operation process of the grounding wire, that is, the grounding terminal should be installed first, and then the conductor terminal should be connected. When removing, the order should be reversed to ensure the safety of the entire operation and maintenance operation. Current technical means have not been able to implement mandatory locking control from a technical level. In actual operation, if this order is incorrectly executed, such as touching the conductor terminal first when hanging, or removing the grounding terminal first when removing, it will significantly increase the risk of electric shock for on-site operators, seriously threatening life safety.

[0006] In summary, the current application of grounding devices in power systems has significant security management loopholes, including but not limited to insufficient management of operating authority, lack of status monitoring, and poor technical support for correct operating procedures. These problems urgently need to be overcome through innovative design and technical improvements to improve the safety and efficiency of power operation and maintenance. Therefore, the development of an intelligent grounding device that integrates assembly and disassembly locking functions, has remote status monitoring, and can enforce the correct operating sequence is of great significance to promoting safe production in the power industry. Utility Model Content

[0007] Based on the current status of the background technology, in order to solve the problems of insufficient operation authority management, lack of status monitoring and weak technical support for the correct operation process in the existing grounding device, the utility model proposes an intelligent grounding device with integrated anti-mistaken disassembly and remote monitoring. The utility model is based on NFC induction communication technology and WiFi remote communication technology, and is equipped with an electromagnetic lock locking function, which can smoothly realize the functions of identity recognition, operation locking, standardized assembly and disassembly sequence, remote monitoring and status warning on the grounding wire, thereby effectively ensuring the life safety of on-site operators and the property safety of electrical equipment.

[0008] The utility model adopts the following technical solutions to achieve the purpose:

[0009] An intelligent grounding device integrating mis-disassembly prevention and remote monitoring, wherein the device is arranged at the grounding point of electrical equipment, and comprises a grounding wire, wherein the grounding wire comprises a grounding end and a conductor end; the device further comprises a position switch, a first electromagnetic lock, an NFC identification controller and a WiFi control component; the position switch and the first electromagnetic lock are both arranged on the grounding end, the first electromagnetic lock is respectively connected to the position switch, the NFC identification controller and the WiFi control component, and the position switch is also connected to the WiFi control component; the signal state of the position switch matches the installation state of the grounding end, the NFC identification controller has an NFC identification card that is inductively matched therewith, and the WiFi control component is communicatively connected to a remote operation and maintenance monitoring center.

[0010] Furthermore, the device also includes a second electromagnetic lock; the second electromagnetic lock is arranged on the conductor end, the second electromagnetic lock is connected to the position switch, and the conductor end is connected to the electrical equipment.

[0011] Specifically, the signal state of the position switch includes a closed signal and an open signal, the closed signal corresponds to the installed state of the matching ground terminal, and the open signal corresponds to the uninstalled state of the matching ground terminal; the lock core state of the second electromagnetic lock matches the signal state of the position switch, the closed signal corresponds to the released state of the matching second electromagnetic lock, and the open signal corresponds to the locked state of the matching second electromagnetic lock.

[0012] Furthermore, the device also includes a power supply component; the power supply component is respectively connected to the first electromagnetic lock, the second electromagnetic lock, the NFC identification controller and the WiFi control component.

[0013] Furthermore, the power supply component is also connected to the WiFi control component through a position switch; a power conversion circuit is also provided between the connection lines of the position switch and the WiFi control component; the output end of the power conversion circuit is connected to the grounding status detection end of the WiFi control component; and a safety isolation relay is also provided between the connection of the power conversion circuit and the WiFi control component.

[0015] Specifically, the first electromagnetic lock has a release setting input terminal and a lock setting input terminal; the identification signal output terminal of the NFC identification controller is connected to the release setting input terminal, and the signal change output terminal of the position switch is connected to the lock setting input terminal.

[0016] In summary, due to the adoption of this technical solution, the beneficial effects of the utility model are as follows:

[0017] 1. Enhanced safety locking mechanism: The utility model uses NFC technology to achieve identity verification of on-site operators, ensuring that only authorized personnel can install and remove the grounding wire, fundamentally solving the loopholes in operation authority management. Combined with the intelligent control of the electromagnetic lock, it ensures that the installation and removal of the grounding wire strictly follow the correct safety procedures, that is, when installing, first fix the grounding end, then connect the conductor end, and when removing, perform the reverse order, effectively avoiding the risk of electric shock caused by improper operation.

[0018] 2. Real-time remote status monitoring: Utilizing WiFi remote communication technology, the utility model can transmit the status of the grounding wire to the remote operation and maintenance monitoring center in real time, so that the operation and maintenance management personnel can remotely monitor the working status of multiple grounding wires. Once the grounding status changes abnormally, the system will immediately issue an alarm, greatly improving the fault response speed and processing efficiency, and ensuring the stable operation of power facilities.

[0019] 3. Intelligent operation guidance and anti-mistaken removal function: Through its component configuration, the intelligent grounding device can not only identify the identity of on-site operators, but also compulsorily execute the operating procedures under safety regulations based on the cooperation of electromagnetic locks, prevent non-sequential operations, and prevent the phenomenon of mistaken removal of grounding terminals. This eliminates the possibility of illegal operations at the technical level and provides additional safety protection for on-site operators.

[0020] 4. Convenient installation and maintenance: The intelligent grounding device of the utility model focuses on practicality and convenience in design. It adopts wireless communication, which eliminates the wiring difficulties of wired communication in complex scenarios of power systems, making the installation process simpler and faster. At the same time, it also reduces the subsequent maintenance costs and difficulty, and adapts to the needs of rapid response and flexible deployment of modern power facilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a schematic diagram of the structural connection of the intelligent grounding device of the utility model. DETAILED DESCRIPTION

[0022] 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.

[0023] 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.

[0024] Example 1

[0025] like Figure 1 As shown, an intelligent grounding device integrating anti-misdisassembly and remote monitoring is provided at the grounding point of the electrical equipment, and includes a grounding wire, a position switch, a first electromagnetic lock, a second electromagnetic lock, an NFC identification controller and a WiFi control component.

[0026] Among them, the grounding wire includes a grounding end and a conductor end, the position switch and the first electromagnetic lock are both arranged on the grounding end, the first electromagnetic lock is respectively connected to the position switch, the NFC identification controller and the WiFi control component, and the position switch is also connected to the WiFi control component. The signal state of the position switch matches the installation state of the grounding end, the NFC identification controller has an NFC identification card that matches its induction, and the WiFi control component communicates with the remote operation and maintenance monitoring center. The second electromagnetic lock is arranged on the conductor end (such as the grounding wire clamp actually used), the second electromagnetic lock is connected to the position switch, and the conductor end is connected to the electrical equipment.

[0027] First of all, it should be noted that the lock core states of the first electromagnetic lock and the second electromagnetic lock both include a released state and a locked state. In the default power-on mode and when the power is off, the lock core states of both are in a locked state; when in a locked state, the electromagnetic lock will prevent the installation or removal and connection of the corresponding end (ground end or conductor end); only when the electromagnetic lock is in a released state can the corresponding end successfully complete the installation or removal and connection operations. This type of locking mechanism is the key point for this embodiment to achieve its corresponding effect.

[0028] This embodiment does not limit the specific structure of the electromagnetic lock and the corresponding end. Generally, the mechanical structure inside the electromagnetic lock (such as a spring or other form of retaining mechanism) will keep the lock core in a locked state, preventing the universal connector from being plugged in and out, etc. When released, the connector can be plugged in and out and the components can be moved. Therefore, the design can be selected according to the actual needs and specifications of the grounding device, and will not be repeated here.

[0029] In this embodiment, the signal state of the position switch includes a closed signal and an open signal, the closed signal corresponds to the state in which the ground terminal is installed, and the open signal corresponds to the state in which the ground terminal is not installed. In order to facilitate the realization of the grounding device's requirements for a standardized installation and removal sequence, the lock core state of the second electromagnetic lock is strictly matched only with the signal state of the position switch, that is, the closed signal corresponds to the release state of the second electromagnetic lock, and the open signal corresponds to the locking state of the second electromagnetic lock.

[0030] The position switch can be 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 grounding device is mainly to detect whether the grounding wire has been correctly installed or removed, so its function is realized by a 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, which can be used to sense state changes and conduct specific circuits to transmit electrical signals.

[0031] 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.

[0032] In this embodiment, Figure 1 As shown, the grounding device also includes a power supply component; the power supply component is respectively connected to the first electromagnetic lock, the second electromagnetic lock, the NFC identification controller and the WiFi control component. The power supply component includes a detachable battery and / or a solar panel. This configuration can improve the independence and endurance of the grounding device, thereby ensuring that the grounding device can still have a state detection and control effect for a long time on the basis of normal operation without an external power supply.

[0033] The power supply component is also connected to the WiFi control component through a position switch; a power conversion circuit is also provided between the connection lines of the position switch and the WiFi control component; 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 of the power conversion circuit and the WiFi control component.

[0034] The WiFi control component determines the installation status of the ground terminal by enabling the signal of its ground status detection terminal; the setting 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.

[0035] In this embodiment, the NFC identification controller has a built-in storage unit, which stores the electrical equipment information corresponding to the current grounding device; the NFC identification card has a unique serial number embedded in it, which matches the corresponding electrical equipment information; the WiFi control component has a built-in grounding wire identity information storage device, which stores the grounding wire identity information corresponding to the current grounding device.

[0036] In the remote operation and maintenance monitoring center, the information of each electrical device will be matched with its corresponding grounding wire identity information for storage and management. Therefore, the above features are the key to ensuring the correct identification of the grounding wire identity, avoiding the selection or connection of the wrong grounding wire, and failing to effectively ground the electrical equipment actually under repair. Especially in the case where there is a certain distance between the electrical equipment and the grounding point, if the on-site operator installs the wrong grounding wire at the grounding point (for example, the grounding wire actually corresponds to the remaining electrical equipment that is not under repair), and returns to the electrical equipment to be repaired and connects the conductor end corresponding to the original correct grounding wire, there will be a serious safety hazard of not being grounded.

[0037] As for the unique serial number embedded in each NFC identification card, namely UID, the UID is set when the NFC identification card leaves the factory and cannot be modified; it can be matched with the corresponding electrical equipment information at the remote operation and maintenance monitoring center of the power system. In this way, only when the NFC identification controller of the corresponding grounding device reads the preset matching UID, the corresponding electromagnetic lock will be operated.

[0038] As a preferred embodiment of this embodiment, the NFC identification controller also has a built-in encryption key identification component, and the NFC identification card also has embedded encryption key information. The encryption key information can be given or updated by the remote operation and maintenance monitoring center before each operation and maintenance task. After the encryption key identification component calculates whether it is correct, it outputs the corresponding signal to control the electromagnetic lock. This means that even if a copied or forged NFC identification card with the same UID appears, the electromagnetic lock cannot be operated without the correct key, thereby further preventing the grounding wire in use from being accidentally removed. The NFC identification card is carried by the on-site operator performing the current operation and maintenance task to ensure that only he or she has authorization.

[0039] In this embodiment, unlike the second electromagnetic lock, the lock cylinder state is strictly matched only with the signal state of the position switch, and the first electromagnetic lock is additionally provided with a release setting input terminal and a lock setting input terminal. The identification signal output terminal of the NFC identification controller is connected to the release setting input terminal, and the signal change output terminal of the position switch is connected to the lock setting input terminal.

[0040] The so-called signal change of the position switch is specifically described as follows: when the on-site operator installs the grounding end of the grounding wire, the signal state of the position switch changes. This change in signal state (i.e., from open to closed, with a jump edge for signal output) will cause the first electromagnetic lock to lock in place (since the electromagnetic lock is in a released state when installed). Then a certain delay time can be preset, and the first electromagnetic lock will automatically become a locked state. Before the on-site operator confirms the NFC identification induction, the grounding end of the grounding wire cannot be removed, thereby preventing unrelated personnel on site from accidentally operating or removing the grounding wire, and significantly improving the safety, efficiency and intelligence level of operation and maintenance tasks.

[0041] Example 2

[0042] On the basis of Example 1, this example introduces a control method for an intelligent grounding device integrating anti-mistaken disassembly and remote monitoring. The hardware basis of this method is the intelligent grounding device of Example 1.

[0043] First, when the electrical equipment using this device needs to be operated or repaired, the following steps are used to complete the installation of its grounding wire and the control of the grounding device:

[0044] S11. The remote operation and maintenance monitoring center determines the electrical equipment information, selects the corresponding NFC identification card and sends it to the on-site operator; the on-site operator arrives at the grounding point of the electrical equipment;

[0045] S12, turning on the power switch of the power supply component itself, the first electromagnetic lock, the second electromagnetic lock, the NFC identification controller and the WiFi control component are powered on and enter the running state; the first electromagnetic lock and the second electromagnetic lock are both in the locked state; the remote operation and maintenance monitoring center simultaneously receives the report of the WiFi control component storing the information in its own ground wire identity information storage device.

[0046] S13, placing the NFC identification card close to the sensing position of the NFC identification controller, the NFC identification controller outputs an identification signal, the first electromagnetic lock changes to a released state, and the on-site operator installs the grounding end of the grounding wire;

[0047] S14. After the grounding end of the grounding wire is installed, the signal state of the position switch changes from an open signal to a closed signal; 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 end of the WiFi control component;

[0048] S15, after the WiFi control component confirms that the signal of its grounding state 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" state information to the outside; then the first electromagnetic lock is changed to a locked state;

[0049] S16. When the signal state of the position switch changes from an open signal to a closed signal and continues to output, the second electromagnetic lock changes to a released state, and the on-site operator connects the conductor end of the grounding wire to the electrical equipment, completes the installation of the grounding wire, and starts to perform operation or maintenance or repair operations on the electrical equipment.

[0050] In step S15 of the above process, a preset delay time method can be used to change the first electromagnetic lock into a locked state. The specific operation is: after the grounding end of the grounding wire is installed, the signal state of the position switch changes from an open signal to a closed signal; the change in the signal state here is input to the lock position input end of the first electromagnetic lock, and after the preset delay time, the first electromagnetic lock changes to a locked state.

[0051] In addition, due to the function of the WiFi control component in the grounding device, it has the characteristics of remote monitoring, and the remote operation and maintenance monitoring center can also be used to remotely control the first electromagnetic lock to a locked state. The specific operation is: after the remote operation and maintenance monitoring center confirms that the grounding end of the grounding wire has been installed, the WiFi control component is used to control the first electromagnetic lock to be in a locked state, thereby locking the installation state of the grounding end.

[0052] In this embodiment, after the electrical equipment to which the device is applied is received for operation and maintenance or overhaul, the following steps are used to complete the removal of the grounding wire and the control of the grounding device:

[0053] S21. The on-site operator disconnects the electrical equipment from the conductor end of the grounding wire and reports the completion of the operation and maintenance or overhaul and the conductor end disconnection information to the remote operation and maintenance monitoring center;

[0054] S22, placing the NFC identification card close to the sensing position of the NFC identification controller, the NFC identification controller outputs an identification signal, the first electromagnetic lock changes to a released state, the on-site operator then removes the grounding end of the grounding wire, and the signal state of the position switch changes from a closed signal to an open signal;

[0055] S23: 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;

[0056] S24, when the signal state of the position switch changes from a closed signal to an open signal and continues to output, the first electromagnetic lock and the second electromagnetic lock both change to a locked state;

[0057] S25. The on-site operator turns off the power switch of the power supply assembly, stores the grounding wire and its accessories, completes the removal of the grounding wire, and returns the NFC identification card to the remote operation and maintenance monitoring center.

[0058] In step S24 of the above process, a preset delay time method can be used to change the first electromagnetic lock into a locked state. The specific operation is: after the grounding end of the grounding wire is removed, the signal state of the position switch changes from a closed signal to an open signal; the change in the signal state here is input to the lock set input end of the first electromagnetic lock, and after the preset delay time, the first electromagnetic lock changes to a locked state.

[0059] In addition, due to the function of the WiFi control component in the grounding device, it has the characteristics of remote monitoring, and the remote operation and maintenance monitoring center can also be used to remotely control the first electromagnetic lock to a locked state. The specific operation is: after the remote operation and maintenance monitoring center confirms that the grounding end of the grounding wire has been removed, the WiFi control component is used to control the first electromagnetic lock to be in a locked state, thereby locking the grounding end to prevent other operation and maintenance tasks from misusing it or performing unauthorized operations.

[0060] In this embodiment, the effect of the above method on preventing accidental disassembly is manifested in that when the grounding end of the grounding wire is installed, the first electromagnetic lock will enter a locked state, and the grounding end cannot be removed from the grounding point to disconnect the reliable connection with the earth; even if the on-site operator performs operation and maintenance inspection operations at the electrical equipment at a certain distance from the grounding point, it can prevent unrelated personnel on site from removing the grounding wire currently in use, because the release of the first electromagnetic lock is determined by the NFC identification card carried by the on-site operator. At this time, even if others turn off the power of the grounding device or the device is accidentally powered off, the first electromagnetic lock is in a locked state; and the conductor end corresponding to the second electromagnetic lock is located at the electrical equipment where the on-site operator is located, and has been connected to the electrical equipment, which will not affect the operation and maintenance safety of the on-site operator.

[0061] Normally, as long as the grounding end of the grounding wire is correctly installed, the second electromagnetic lock will be in a released state, making it convenient for on-site operators to connect or disconnect the conductor end it controls with the electrical equipment. The second electromagnetic lock is the key to cooperating with the other components to achieve mandatory standardized installation and disassembly sequences. During the installation of the grounding wire, if you want to connect the conductor end first and then install the grounding end, you will find that because the grounding end is not correctly installed, the signal state of the position switch is a disconnect signal, and the second electromagnetic lock is in a locked state, and its corresponding conductor end cannot be connected to the electrical equipment; only after the grounding end is correctly installed first, the second electromagnetic lock will become released, and its conductor end can be connected to the electrical equipment.

[0062] Similarly, during the removal of the grounding wire, when the on-site operator completes the specific operations of operation and maintenance and wants to remove the grounding wire, if he first releases the first electromagnetic lock through NFC sensing identification and removes the grounding end, the signal state becomes disconnected due to the action of the position switch. At this time, the second electromagnetic lock corresponding to the conductor end still connected to the electrical equipment will become locked, and the conductor end cannot be disconnected from the electrical equipment. This reminds the on-site operator that the sequence is wrong and he should immediately restore the installation of the grounding end, and then return to the electrical equipment to disconnect the conductor end on the electrical equipment before continuing to remove the grounding end.

[0063] As a preferred embodiment of this invention, due to the status monitoring of the WiFi control component and its communication connection with the remote operation and maintenance monitoring center, if the on-site operator changes the first electromagnetic lock to a released state through NFC sensing without reporting the body end disconnection information to the remote operation and maintenance monitoring center, intending to remove the grounding end first, and when the wrong removal sequence is about to be executed, the remote operation and maintenance monitoring center can directly issue an alarm to the on-site operator, and can also further re-lock the first electromagnetic lock corresponding to the grounding end, thereby forcing the on-site operator to first disconnect the conductor end from the electrical equipment.

[0064] Generally, for maintenance and repair operations performed on electrical equipment at a certain distance from the grounding point, after completing the corresponding operations at the electrical equipment, the on-site operators usually disconnect the conductor end on the electrical equipment before going to the grounding point to remove the grounding wire. After the grounding wire is removed, the first electromagnetic lock also changes to a locked state. After the on-site operator turns off the power and puts it away, he can return to the remote maintenance monitoring center to report the maintenance and repair results and return the NFC identification card. Since the signal state of the position switch changes when the grounding wire is removed, the first electromagnetic lock and the second electromagnetic lock are eventually locked accordingly, waiting for the next maintenance and repair task while preventing misuse.

[0065] In summary, the intelligent grounding device of the utility model has achieved a comprehensive upgrade of the key safety links in the maintenance operation of electrical equipment through technological innovation. It not only significantly improves the safety and efficiency of operations, but also provides technical support for the intelligent management of power systems. It is of great value to promote safe production and sustainable development in the power industry.
