Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides a device for protecting an outlet pressure plate from mis-touching, comprising at least one set of mis-touching units 100, including a wiring assembly 101, a pressure plate 102 arranged on one side of the wiring assembly 101, a docking assembly 103 arranged on the pressure plate 102, and a fixing cap 104 arranged at the end of the docking assembly 103;

[0039] The collection unit 200 includes a docking piece 201 that cooperates with the insertion and withdrawal error contact unit 100, a collector 202 disposed on one side of the docking piece 201, and an electrical cabinet 203 disposed on the back of the docking piece 201;

[0040] Each group of docking components 103 is collected and aggregated into the collector 202 through the docking piece 201 .

[0041] Furthermore, the docking assembly 103 includes a clamping plate 103a disposed on the outside of the pressure plate 102, a connecting plate 103b disposed on one side of the clamping plate 103a, and a docking rod 103c disposed on one side of the connecting plate 103b.

[0042] Further, the docking member 201 includes a magnetic strip 201a disposed at the bottom thereof;

[0043] The docking rod 103c includes a magnet M disposed at an end thereof;

[0044] After the magnetic strip 201a contacts the magnet M, the collector 202 determines whether the pressing plate is mistakenly ejected.

[0045] It should be noted that the wiring assembly 101 is used to connect the internal circuit of the relay protection cabinet to ensure that the current can pass smoothly. The wiring assembly 101 is usually made of conductive materials, such as copper or aluminum, and has good conductivity. It includes a plurality of terminals for connecting with other components in the relay protection cabinet. The pressure plate 102 is installed on one side of the wiring assembly 101 and is used to control the insertion and withdrawal operation of the protection outlet pressure plate of the relay protection cabinet. An operating handle is provided on the pressure plate 102 to facilitate manual operation by electrical personnel. A card slot is provided on one side of the pressure plate 102 for fixing the docking assembly 103. The docking assembly 103 is installed on the pressure plate 102 and is used to cooperate with the docking piece 201 of the collection unit 200 to transmit the status information of the pressure plate 102. The card plate 103a is fixed on the outer side of the pressure plate 102 for fixing the docking assembly 103. The connecting plate 103b is connected to one side of the card plate 103a for connecting the docking rod 103c. It is connected to one side of the connecting plate 103b through the docking rod 103c, and a magnet M is provided at the end. The clamping plate 103a, the connecting plate 103b, and the docking rod 103c are usually made of non-conductive materials to prevent current leakage. The magnet M is used to contact the magnetic strip 201a of the docking member 201 to transmit the status information of the pressure plate 102. The fixing cap 104 is installed at the end of the docking assembly 103 to fix the docking assembly 103 to prevent it from loosening or falling off. The fixing cap 104 is connected to the docking rod 103c by threads or other fixing methods to ensure the stability of the docking assembly 103.

[0046] Preferably, the docking piece 201 cooperates with the docking assembly 103 of the insertion and withdrawal false contact unit 100 to collect status information of the pressure plate 102. The magnetic strip 201a is arranged at the bottom of the docking piece 201, and is used to contact the magnet M at the end of the docking rod 103c. The magnetic strip 201a is usually made of magnetic material and can generate magnetic force with the magnet M. The fixing seat 201b is used to fix the docking piece 201 to ensure its stable position in the relay protection cabinet. The collector 202 is installed on one side of the docking piece 201, and is used to collect status information of the docking assembly 103 and transmit the information to the system. The collector 202 is usually composed of a microprocessor, a sensor and a communication module. The microprocessor is used to process the collected data, the sensor is used to detect the magnetic force change, and the communication module is used to transmit the data to the system.

[0047] Working principle: When the relay protection cabinet is in normal operation, the pressure plate 102 is located at the initial position, the magnet M of the docking rod 103c contacts the bottom of the magnetic strip 201a of the docking piece 201, and the collector 202 detects the change in magnetic force.

[0048] If the electrical personnel accidentally touch the relay protection cabinet protection outlet pressure plate 102, the magnet M on the wrong position of the docking rod 103c is a certain distance away from the magnetic strip 201a, and the collector 202 will send an alarm signal to remind the operator that the current position is wrong. The collector 202 transmits the status information of the pressure plate 102 to the system in real time, and the operator can view the position status of each protection outlet pressure plate in real time on the system interface to ensure the correctness and safety of the operation.

[0049] In summary, by introducing the magnetic detection mechanism, it is effectively prevented that the electrical personnel make mistakes when performing the operation of the protection outlet pressure plate, thereby improving the safety of the operation. The collector 202 transmits the status information of the pressure plate 102 to the system in real time, realizing the real-time monitoring of the position status of the protection outlet pressure plate of the relay protection device. The risk of misoperation caused by human factors is reduced, and the reliability of the relay protection device is improved.

[0050] Example 2

[0051] Reference Figure 1 to Figure 5 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: it also includes a wiring assembly 101 including an insulating sleeve 101a disposed on the end surface of the electrical cabinet 203, and a terminal 101b disposed inside the insulating sleeve 101a;

[0052] The pressing plate 102 includes a sleeve hole 102a disposed at one end thereof and a docking groove 102b disposed at the other end thereof.

[0053] Furthermore, the clamping plate 103a includes a U-shaped clamp 103a-1 that can be clamped on both sides of the pressing plate 102, and an L-shaped column 103a-2 arranged at the end of the U-shaped clamp 103a-1.

[0058] The balloon 103c-11 and the ball column 103b-2 are movably engaged with each other.

[0059] It should be noted that the terminal 101b is arranged on the inner side of the insulating sleeve 101a, and is used to connect to the internal circuit of the relay protection cabinet. The pressure plate 102 is installed on one side of the wiring assembly 101, and is used to control the insertion and withdrawal operation of the protection outlet pressure plate of the relay protection cabinet. The sleeve hole 102a is arranged at one end of the pressure plate 102, and is used to fix the pressure plate 102 on the wiring assembly 101. The sleeve hole 102a is usually circular or oval, and the size matches the fixed point on the wiring assembly 101. The docking groove 102b is arranged at the other end of the pressure plate 102, and is used to connect with the docking assembly 103. The docking groove 102b is usually rectangular or U-shaped, and the size matches the clamping plate 103a of the docking assembly 103. The docking assembly 103 is installed on the pressure plate 102, and is used to cooperate with the docking piece 201 of the collection unit 200 to transmit the status information of the pressure plate 102.

[0060] Preferably, the U-shaped clamp 103a-1 can be clamped on both sides of the pressure plate 102 to fix the docking assembly 103. The U-shaped clamp 103a-1 is usually made of metal material and has high mechanical strength. The L-shaped column 103a-2 is arranged at the end of the U-shaped clamp 103a-1 to support the connecting plate 103b. The clamp 103b-1 is clamped on the outside of the U-shaped clamp 103a-1 to fix the connecting plate 103b. The ball column 103b-2 is arranged on both sides of the clamp 103b-1 to cooperate with the connecting sleeve 103c-1 of the docking rod 103c. The connecting sleeve 103c-1 is sleeved on one side of the ball column 103b-2 to connect the docking rod 103c. A ball balloon 103c-11 is provided inside the connecting sleeve 103c-1 to cooperate with the ball column 103b-2. The threaded column 103c-2 is arranged on one side of the connecting sleeve 103c-1, and is used to connect with the fixing cap 104. The connecting cap 103c-3 is arranged on one side of the threaded column 103c-2, and is used to fix the docking rod 103c. The connecting cap 103c-3 is usually made of insulating material to prevent current leakage. The fixing cap 104 is installed at the end of the docking assembly 103, and is used to fix the docking assembly 103 to prevent it from loosening or falling off.

[0061] Preferably, the magnetic strip 201a is disposed at the bottom of the docking piece 201, and is used to contact the magnet M at the end of the docking rod 103c. The magnetic strip 201a is usually made of magnetic material, and can generate magnetic force with the magnet M. The fixing seat 201b is used to fix the docking piece 201 to ensure its stable position in the relay protection cabinet.

[0062] During use, when the relay protection cabinet is in normal operation, the pressing plate 102 is located at the initial position, and at this time, the magnet M of the docking rod 103c is in close contact with the magnetic strip 201a at the bottom of the docking piece 201. The collector 202 confirms the position state of the pressing plate 102 by detecting the change in magnetic force. In this state, the collector 202 detects a stable magnetic signal, indicating that the pressing plate 102 is in the correct initial position.

[0063] If the electrical personnel accidentally touch the protection outlet pressure plate 102 of the relay protection cabinet during operation, causing the pressure plate 102 to move to the wrong position, the distance between the magnet M on the docking rod 103c and the magnetic strip 201a will change. This change will be detected by the collector 202, and the collector 202 will immediately send an alarm signal to prompt the operator that the current position is wrong. This mechanism can quickly identify and warn of misoperation, thereby avoiding the failure of the relay protection device due to improper operation. At the same time, the collector 202 transmits the status information of the pressure plate 102 to the system in real time. The operator can view the position status of each protection outlet pressure plate in real time through the system interface to ensure the correctness and safety of all operations. This real-time monitoring function not only improves the safety of operation, but also enhances the reliability of the system, ensuring that the relay protection device is always in the best working condition.

[0064] Example 3

[0065] Reference Figure 5 , which is the third embodiment of the present invention, and which is different from the first two embodiments in that: a device for protecting the outlet pressure plate from mis-touching is also provided, including moving the pressure plate to make the magnet of the docking rod contact the magnetic strip;

[0066] The collector detects the change in magnetic force, confirms that the pressure plate is correctly inserted and retracted, and transmits the status information to the system;

[0067] Check the collector to see if a stable magnetic signal is detected and confirm whether the pressure plate is in the correct position;

[0068] When the pressure plate is touched by mistake, the distance between the magnet of the docking rod and the magnetic strip changes;

[0069] The collector detects the magnetic change and immediately sends out an alarm signal to remind the operator that the current position is wrong.

[0070] It should be noted that the electrical personnel manually move the pressing plate 102 according to the operating instructions so that the magnet M of the docking rod 103c contacts the magnetic strip 201a of the docking piece 201. The collector 202 detects the change in magnetic force, confirms that the pressing plate 102 has been correctly put in and out, and transmits the status information to the system in real time. When the relay protection cabinet is in normal operation, the pressing plate 102 should be in the initial position, and the magnet M of the docking rod 103c is in close contact with the magnetic strip 201a of the docking piece 201. The system checks whether the collector 202 detects a stable magnetic signal and confirms that the pressing plate 102 is in the correct initial position. If the electrical personnel touch the pressing plate 102 by mistake, the distance between the magnet M on the docking rod 103c and the magnetic strip 201a will change. The collector 202 detects the change in magnetic force and immediately sends an alarm signal to prompt the operator that the current position is wrong. The operator should stop the operation immediately, reconfirm the operation position, and ensure the correctness of the operation.

[0071] In summary, by introducing the magnetic detection mechanism, it is effective to prevent electrical personnel from making misoperations when performing the operation of the protective outlet pressure plate, which significantly improves the safety of the operation. The collector 202 transmits the status information of the pressure plate 102 to the system in real time, realizes real-time monitoring of the position status of the protective outlet pressure plate of the relay protection device, and ensures the correctness and safety of the operation. It reduces the risk of misoperation caused by human factors and improves the reliability of the relay protection device. Through real-time monitoring and misoperation detection, it is ensured that the relay protection device is always in the best working state, which improves the reliability of the entire power system.
