Description

[0001] The present application relates to hard pressure plate detection technology, and in particular to an anti-misoperation intelligent detection pressure plate. BACKGROUND

[0002] The safe operation of the relay protection system is one of the most critical safety guarantees in the power system, especially in complex operating environments such as high-voltage substations, the stability and reliability of which directly affect the safety and continuous power supply of the power grid. As the core operating element in the relay protection device, the hard pressure plate must provide a visible and obvious breaking point, and has an irreplaceable role in the trip and close loop and protection function on-off control. It not only provides an intuitive basis for the state judgment for the operating personnel, but also brings great convenience for equipment maintenance and daily operation management.

[0003] However, since the actual on-off state of the hard pressure plate is difficult to directly monitor under normal operating conditions (no trip command), and its on-off operation completely depends on manual execution, there is a lack of effective state feedback mechanism, which is prone to cause protection function failure due to human error or poor mechanical contact, and even cause serious accidents. For example, in the scene of frequent operation or emergency treatment, if the operating personnel cannot accurately confirm the state of the pressure plate, it may cause problems such as missing and misoperation, thereby affecting the correct action of the entire protection system and threatening the safety of the power grid. Therefore, a technical solution capable of realizing the linkage monitoring of mechanical operation and circuit state is urgently needed to improve the accuracy and safety of the hard pressure plate operation.

[0031] In this embodiment, the pressing plate 1 is a hard pressing plate. Due to the particularity of the relay protection device, there must be a visible and obvious disconnection point in the jump and trip circuit and the protection function on and off, so as to facilitate the operation personnel to quickly and intuitively judge whether the protection function of the relay protection device is put into.

[0032] In addition, the detection assembly 25 is clamped on one side of the pressing plate 1, and the detection assembly 25 realizes the movement of putting into or taking back the pressing plate 1 by detecting the rotation and plug-in of the connecting piece in the pressing plate 1, so as to detect whether the pressing plate 1 is put into use.

[0033] Putting into and taking out operation: when the pressing plate 1 is rotated and plugged into use, the opening and closing assembly 24 is pressed to realize the closing movement of the gate plate, and then the detection assembly 25 is started to record the displacement change. At the same time, the opening and closing assembly 24 drives the communication assembly 22 to close the circuit, and the warning assembly 23 is started to display after receiving the closing signal.

[0034] Reference Figures 1-2 As an optional embodiment, in one embodiment provided in the application, the pressing plate 1 comprises two groups of wiring posts 11, a fixed sleeve 12 sleeved on the outer side of the wiring post 11, a gate knife 13 hinged on one side of the wiring post 11, an insulating clamp 14 sleeved on the outer side of the gate knife 13, and a fixed cap 15 threadedly connected at the end of the wiring post 11.

[0035] The pressing plate 1 comprises two groups of wiring posts 11, a fixed sleeve 12 sleeved on the outer side of the wiring post 11, a gate knife 13 hinged on one side of the wiring post 11, an insulating clamp 14 sleeved on the outer side of the gate knife 13, and a fixed cap 15 threadedly connected at the end of the wiring post 11.

[0036] In one embodiment provided in the present application, the fixing sleeve 12 comprises a sleeve 121 clamped outside the terminal post 11, and a connecting seat 122 protruding on both sides of the sleeve 121.

[0037] In the embodiment, the pressing plate 1 is a hard pressing plate, which is convenient for the operator to quickly and intuitively judge whether the protection function of the relay protection device is put into operation. The pressing plate 1 comprises two groups of terminal posts 11 connected to the electrical cabinet, the terminal post 11 is fixed by the fixing sleeve 12 sleeved outside the terminal post 11, and the terminal post 11 provides installation space for the rotation of the switch 13.

[0038] Preferably, the switch 13 is a conductive metal sheet, one side of which is provided with a circular hole, which is convenient for sleeving on the terminal post 11; the other side of the switch 13 is notched, which is convenient for the switch 13 to rotate with the terminal post 11 on the other side as the center, and the notch of the switch 13 is inserted into the terminal post 11 on the other side.

[0039] Preferably, the circular hole of the switch 13 is in sliding fit with the terminal post 11, allowing it to rotate around the axis of the terminal post 11; the notch structure is in plug-in fit with the end face of the terminal post 11 on the opposite side, the edge of the notch is designed as an involute curve to control the circuit on-off through the rotation angle, and the contact area with the terminal post 11 during rotation is ensured to change smoothly with the angle, avoiding abnormal operation caused by jamming.

[0040] Preferably, the insulating clamp 14 of insulating material is clamped on the plate body of the switch 13, one side of the insulating clamp 14 is rectangular, which is convenient for inserting into the plate body of the switch 13; and a protrusion is protruded on the end face of the insulating clamp 14, which is convenient for the operator to move the protrusion on the insulating clamp 14 to realize the putting and withdrawing operation of the whole switch 13. The installation mode of the insulating clamp 14: the rectangular insertion part is in interference fit with the plate body of the switch 13, ensuring firm fixation; the contact surface between the protrusion and the operator's fingers is designed as an arc shape, reducing the operation resistance. Anti-slip texture is provided on the surface of the protrusion to prevent operation failure in wet and slippery environment; the insulating clamp 14 wraps the exposed metal part of the switch 13 as a whole, avoiding direct contact of the human body with the live area.

[0041] Preferably, the upper and lower ends of the terminal post 11 are both screw rods, which are convenient for the lower end to be fixed and connected to the wall surface of the electrical cabinet; and the upper end is fixed to the terminal post 11 by the interference fit + elastic washer of the fixing cap 15. By loosening the fixing cap 15 on one side, the normal putting and withdrawing of the switch 13 is realized. The interference fit of the fixing cap 15 provides axial positioning, and the elastic washer inside the fixing cap 15 compensates for the size deviation caused by temperature change, ensuring the stability of the switch 13 in long-term operation. The end of the fixing cap 15 is designed as a hexagonal shape, which is suitable for common wrenches; after loosening, the switch 13 can be rotated by 180° to complete the putting and withdrawing action, and after rotation, the fixing cap 15 is automatically locked.

[0042] Further, the fixing sleeve is composed of sleeve 121 embracing the terminal post 11 outside and connecting seat 122 connecting the two sleeves 121 together. The sleeve 121 is a hollow tubular structure made of high polymer insulating material such as polyimide, with its inner diameter forming a clearance fit with the outer diameter of the terminal post 11, and with anti-skid lines on its surface to enhance holding stability. The connecting seat 122, which is a platform formed by the clearance between the sleeves 121, provides connecting space for the detection unit 2.

[0043] The sleeve 121 realizes axial positioning of the terminal post 11 through elastic embracing force, and has both mechanical protection and electrical isolation, which can effectively absorb external vibration interference to the internal circuit. The connecting seat 122 and the sleeve 121 are an integral structure, and the connecting seat 122 provides connecting space for the detection unit 2 connected to the pressing plate 1. The inner wall of the sleeve 121 is provided with annular elastic protrusions, which absorb external impact energy through deformation to prevent displacement of the terminal post 11 due to vibration.

[0044] Reference Figure 2 As an optional embodiment, the detection assembly 25 includes a bottom plate 251 inserted into the end of the connecting seat 122, a detection module 252 mounted on the end face of the bottom plate 251, and a cover plate 253 buckled on the end face of the bottom plate 251.

[0045] The cover plate 253 includes a hoop clamp 2531 protruding from one side thereof.

[0046] In this embodiment, the detection assembly 25 includes a bottom plate 251 inserted into the end of the connecting seat 122, a detection module 252 mounted on the end face of the bottom plate 251, and a cover plate 253 buckled on the end face of the bottom plate 251. The cover plate 253 includes a hoop clamp 2531 protruding from one side thereof.

[0047] Preferably, the bottom plate 251 is designed in a trapezoidal structure, with the narrow end inserted into the end of the connecting seat 122 to provide mounting space for the opening and closing assembly 24, and the wide face serving as the mounting base of the detection module 252, with anti-skid lines on the surface to enhance friction with the connecting seat 122.

[0048] The cover plate 253 is fixed to the end face of the bottom plate 251 by buckling structure, with a hoop clamp 2531 protruding from one side thereof. The inner diameter of the hoop clamp 2531 matches the diameter of the sleeve 121, and realizes stable connection with the pressing plate 1 through elastic clamping force to prevent loosening due to vibration during operation. The trapezoidal structure of the bottom plate 251 forms an insertion fit with the end of the connecting seat 122, with the insertion depth controlled by a limiting boss to ensure installation consistency. The hoop clamp 2531 is attached to the surface of the sleeve 121 through elastic silicone pads, which not only ensures clamping force but also avoids scratching the insulating layer.

[0049] Furthermore, the detection module 252 is a prior art technology, powered by 12V DC, and communicates with the adapter via an RS485 bus. The adapter then connects to the host computer via an RS485 network. Each RS485 bus can support 255 adapters, and each adapter can connect to 81 detection modules 252, meeting the expansion needs of substations with different voltage levels. The hardware requires no address configuration; the adapter only needs to be set with the total number of pressure plates and the address of the sub-nodes. After replacing a damaged pressure plate, it can automatically identify and resume operation without manual intervention. The detection module 252 collects the pressure plate activation / deactivation status in real time and supports locking / unlocking operations. For a locked pressure plate, if forced activation / deactivation is detected, the module will immediately send an error alarm to the host computer and trigger the warning component 23 to display an abnormal signal, such as a flashing red light.

[0050] The preferred detection module 252 adopts aerospace measurement and control technology and WiFi wireless transmission technology to achieve contactless status acquisition; it has a built-in high-energy-density graphene battery and amorphous silicon low-light sensitive solar charging panel to achieve wiring-free installation, and a single charge life of more than 25 years, adapting to long-term operation in complex environments.

[0051] Reference Figures 1-5 As an optional embodiment, the connecting component 22 includes a first guide piece 221 fixedly snapped onto the bottom side of the clamp 21, and a second guide piece 222 snapped onto the other side of the bottom side of the clamp 21.

[0052] In one embodiment provided in this application, the warning component 23 includes a connecting post 231 with wiring connected to one side of the first guide plate 221 and the second guide plate 222 respectively, a lamp post 232 connected to the end of the connecting post 231, and a warning lamp 233 disposed at the end of the lamp post 232.

[0053] In one embodiment provided in this application, the opening and closing assembly 24 includes a first spring piece 241 bolted to one end of the connecting seat 122, and a second spring piece 242 inserted into the groove of the base plate 251.

[0054] In one embodiment provided in this application, the connecting seat 122 includes a column 1221 protruding from its end face;

[0055] The first spring clip 241 includes a fixed end M that is bolted to the end face of the column 1221, and a fastening end N that protrudes from one side of the fixed end M;

[0056] The first spring 241 also includes a spherical surface 2411 protruding from its end face.

[0057] In one embodiment provided in this application, the clamp 21 includes hook feet 211 protruding on both sides thereon;

[0058] The first guide piece 221 is located at the bottom of the second guide piece 222, and the first guide piece 221 comprises a protrusion 2211 protruding from one side thereof.

[0059] In one embodiment provided in the present application, the spherical surface 2411 is in contact with the bottom of the first guide piece 221, and the protrusion 2211 of the first guide piece 221 is attached to the second guide piece 222.

[0060] In the embodiment, the clamp 21 is clamped on the side of the insulating clamp 14, and the bottom of the clamping arm of the clamp 21 extends to form a hook 211, which is clamped on the bottom of the insulating clamp 14. The hook 211 is an outwardly protruding arc edge, and two groups of accommodation grooves are formed in the middle part of the hook 211 on both sides, so that the first guide piece 221 and the second guide piece 222 are embedded and connected on the two groups of hooks 211, thereby realizing the connection bridge. The first guide piece 221 is fixedly clamped on the bottom side of the clamp 21, and a conductive oxide layer is coated on the surface to enhance corrosion resistance. A protrusion 2211 is protruded from one side of the first guide piece 221, and the protrusion 2211 is in elastic contact with the groove of the second guide piece 222, thereby ensuring the stability of the circuit on-off. The second guide piece 222 is clamped on the other side of the bottom side of the clamp 21, and a corresponding groove is formed on the top, which is embedded with the protrusion 2211 of the first guide piece 221. The material of the guide piece is phosphor bronze alloy, which has high conductivity and fatigue resistance.

[0061] In addition, the second guide piece 222 is located on the upper end surface of the first guide piece 221, so that when the switch blade 13 is rotated and inserted into the terminal post 11, the hook 211 protruding from the bottom will press the opening and closing assembly 24 on one side, the opening and closing assembly 24 on one side is bent downward to close, and the first elastic sheet 241 is bent, the switch blade 13 is misaligned with the hook 211, the first elastic sheet 241 is reset to a certain extent, and then the first elastic sheet 241 is connected to the first guide piece 221, the protrusion 2211 of the first guide piece 221 is attached to the second guide piece 222, and a closed loop is formed. When it is withdrawn, the first guide piece 221 is automatically separated, the protrusion 2211 is separated from the second guide piece 222, and the circuit is cut off.

[0062] Preferably, the first elastic sheet 241 is bolted to the column 1221 at one end of the connecting seat 122, the fixed end M is connected to the column 1221 by self-tapping screw, and the buckle end N extends into the groove of the bottom plate 251. The end surface of the elastic sheet protrudes a spherical surface 2411, which can be in contact with the bottom of the first guide piece 221 or attached to the hook 211, and the rolling friction is used to reduce the action resistance.

[0063] The second elastic sheet 242 is inserted into the groove of the bottom plate 251, which is a spring sheet. When the switch blade 13 is rotated and put into use, the first elastic sheet 241 is pressed down by the hook 211, so that the buckle end N is pressed on the end surface of the second elastic sheet 242, thereby deforming the second elastic sheet 242, pushing the first elastic sheet 241 to deform, and driving the communication assembly 22 to close.

[0064] Preferably, the column 1221 surface is plated with a conductive oxide layer to prevent the bullet from being oxidized and causing poor contact after long-term use; its top is provided with a threaded hole, which is screwed with the fixed end M of the first bullet 241 to ensure stability.

[0065] The spherical surface 2411 is formed by stamping the first bullet 241, and the spherical surface 2411 is designed to be in contact with the bottom of the first guide piece 221 using an arc surface to increase the contact area; when the pressing plate is withdrawn, the spherical surface 2411 cannot be limited, and the first bullet 241 automatically rebounds to push the first guide piece 221 and the second guide piece 222 apart, cutting off the circuit of the warning assembly 23.

[0066] When the spherical surface 2411 is separated from the first guide piece 221, the convex block 2211 automatically retracts, the warning light 233 is extinguished, and the state of the pressing plate is directly reflected; if the spherical surface 2411 continues to be touched, the warning light 233 is always on, indicating that the pressing plate has been put into operation.

[0067] When the operator rotates the switch 13 through the convex block of the insulating clamp 14, the switch 13 rotates around the terminal post 11, and the connecting piece is inserted or withdrawn to the other terminal post 11. The rotating action of the switch 13 is transmitted to the clamp 21 through the hook foot 211, and the outer convex arc edge structure of the hook foot 211 ensures stable clamping with the bottom of the insulating clamp 14 to prevent displacement. When the switch 13 is rotated and inserted, the hook foot 211 presses the first bullet 241 of the opening and closing assembly 24, and the fixed end M of the first bullet 241 is bolted to the column 1221 and the buckle end N is deformed. The second bullet 242 spring piece is pressed tightly by the buckle end N, and after the second bullet 242 is deformed, the first bullet 241 is further deformed to form a mechanical linkage. Further, when the first bullet 241 is pressed by the hook foot 211, the spherical surface 2411 does not contact the hook foot 211 after entering the bottom of the switch 13, the first bullet 241 rebounds, and then lifts the first guide piece 221, so that the convex block 2211 is embedded in the groove of the second guide piece 222, forming a closed loop. At this time, the spherical surface 2411 is limited at the bottom of the clamp 21, which also promotes the disengagement of the switch 13.

[0068] When the switch 13 is withdrawn, the spherical surface 2411 is pressed by the first guide piece 221, and the first bullet 241 is completely separated after the spherical surface 2411 is pressed by the hook foot 211, until the first bullet 241 is completely reset, and the spherical surface 2411 is separated from the first guide piece 221, the convex block 2211 is separated from the second guide piece 222, and the circuit is disconnected.

[0069] When the protrusion of the first guide piece 221 is engaged with the second guide piece 222, the circuit of the communication assembly 22 is closed; at this time, the current drives the warning light 233 of the warning assembly 23 to be always on, such as green. The detection module 252 feeds back the input state of the presser plate 1 to the upper computer in real time through the photoelectric sensor or displacement detection unit, and records the operation log. When the protrusion 2211 is separated from the second guide piece 222, the circuit of the communication assembly 22 is disconnected; the warning light 233 is turned off, directly reflecting the exit state of the presser plate. The detection module 252 synchronously updates the state information, and if the presser plate 1 is locked and forcibly put in or taken out by human, the module will trigger an error alarm and make the warning light 233 flash, such as red. If the detection module 252 identifies that the presser plate in the locked state is forcibly taken out, it will send an error signal to the upper computer through the RS485 bus, and at the same time, the warning light 233 switches to a high-frequency flashing mode, prompting the operator to check the operation legality.

[0070] In summary, through the mechanical linkage of the first guide piece 221 and the second guide piece 222 and the circuit closing / disconnection, the warning assembly 23 can reflect the input and output state of the presser plate 1 in real time. The detection module 252 communicates with the upper computer through the RS485 bus, supports remote real-time monitoring of the state of the presser plate, and does not need manual inspection, which improves the operation and maintenance efficiency. The opening and closing assembly 24 is pressed through the linkage of the hook foot 211, which ensures that the presser plate input and output actions are synchronized with the circuit closing / disconnection, avoiding abnormal protection function caused by human error operation.

[0071] Finally, it should be pointed out that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
