Description

Technical Field

[0001] This utility model belongs to the field of electrical component technology, specifically relating to a double-isolation pressure plate for comprehensive anti-misoperation relay protection. Background Technology

[0002] In power systems, circuit breakers are used to connect or disconnect circuits and are crucial for the tripping of protection devices, directly affecting the proper functioning of the protection and its operational output. Relay protection devices in the secondary equipment of a power system are fundamental facilities ensuring the safe operation of primary power equipment. By operating the relay protection circuit breakers, the activation, deactivation, or alteration of the protection device's operating mode can be controlled.

[0003] Currently, when power systems put relay protection into operation, the operating status of the relay protection switch must be carefully confirmed. Forgetting to activate the switch or misoperation could cause primary power equipment to lose protection, endangering the safe operation of the power grid. However, existing relay protection switches lack measures to prevent misoperation, making them highly susceptible to errors and affecting the normal use of relay protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to avoid misoperation while ensuring the normal function of relay protection. In view of the shortcomings of the prior art, a double isolation pressure plate for relay protection is provided for comprehensive prevention of misoperation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a double-gang isolation pressure plate for integrated anti-misoperation relay protection, including a fixed panel, a conductive structure, and a connecting structure. The conductive structure comprises two parts, both of which are installed through the fixed panel. Each conductive structure includes a conductive rod, a first insulating cylinder, and a conductive tube. The first insulating cylinder is fitted onto the conductive rod, and the conductive tube is fitted onto the first insulating cylinder. The connecting structure includes a first conductive plate and a second conductive plate separated from each other. The two ends of the conductive rod are electrically connected to the relay protection circuit and the second conductive plate, respectively. The two ends of the conductive tube are electrically connected to the anti-misoperation interlocking circuit and the first conductive plate, respectively.

[0007] Compared to existing technologies, the advantages of this utility model include: A double-isolation pressure plate for relay protection, comprising a fixed panel, a conductive structure, and a connecting structure, is provided for comprehensive prevention of misoperation. The conductive structure consists of two parts, both of which are installed through the fixed panel to ensure structural stability. A conductive rod, a first insulating cylinder, and a conductive tube form the conductive structure, with the first insulating cylinder fitted onto the conductive rod, and the conductive tube fitted onto the first insulating cylinder. This ensures the independence of the conductive tube and the conductive rod, preventing electrical connection between them. Furthermore, a connecting structure is formed by separately positioned first and second conductive plates.

When the fixed panel, conductive structure and connecting structure are connected to form a double isolation pressure plate for comprehensive anti-misoperation relay protection, or when they are separated, the relay protection circuit and the anti-misoperation interlocking circuit close or open simultaneously. The on / off state of the anti-misoperation interlocking circuit can remind the operator of the on / off state of the relay protection circuit, thereby ensuring that the relay protection circuit remains connected when the circuit is closed, ensuring the normal function of the relay protection while avoiding misoperation.

[0026] One embodiment of this utility model provides a double-barrier isolation pressure plate for comprehensive anti-misoperation relay protection, including a fixed panel 1, a conductive structure 2, and a connecting structure 3. The conductive structure 2 has two components, both of which are installed through the fixed panel 1. The conductive structure 2 includes a conductive rod 21, a first insulating cylinder 22, and a conductive cylinder 23. The first insulating cylinder 22 is fitted onto the conductive rod 21, and the conductive cylinder 23 is fitted onto the first insulating cylinder 22. The connecting structure 3 includes a first conductive plate 31 and a second conductive plate 32 separated by a barrier. The two ends of the conductive rod 21 are electrically connected to the relay protection circuit and the second conductive plate 32, respectively. The two ends of the conductive cylinder 23 are electrically connected to the anti-misoperation interlocking circuit and the first conductive plate 31, respectively.

[0027] Specifically, the fixed panel 1 is a protective screen pressure plate fixed panel with a through hole, the conductive rod 21 is a through conductive copper bolt, the first insulating cylinder 22 is an insulating sleeve, the conductive cylinder 23 is a through conductive copper tube, and the first conductive plate 31 and the second conductive plate 32 are both conductive copper sheets.

[0028] In this embodiment, as Figure 1As shown, a double-isolation pressure plate for relay protection, consisting of a fixed panel 1, a conductive structure 2, and a connecting structure 3, is configured to comprehensively prevent misoperation. The conductive structure 2 has two components, both of which are installed through the fixed panel 1 to ensure structural stability. The conductive structure 2 is composed of a conductive rod 21, a first insulating cylinder 22, and a conductive cylinder 23. The first insulating cylinder 22 is fitted onto the conductive rod 21, while the conductive cylinder 23 is fitted onto the first insulating cylinder 22. This ensures the independence of the conductive cylinder 23 from the conductive rod 21, preventing electrical connection between them. Based on this, a first conductive plate 31 and a second conductive plate 32, separated by a partition, form the connecting structure 3. The two ends of the conductive rod 21 are electrically connected to the relay protection circuit and the second conductive plate 32, respectively. At this point, the two... The conductive rod 21 of the conductive structure 2 is electrically connected through the second conductive plate 32, forming a loop electrically connected to the relay protection circuit. At the same time, the two ends of the conductive cylinder 23 are electrically connected to the anti-misoperation interlocking circuit and the first conductive plate 31, respectively. At this time, the conductive cylinders 23 of the two conductive structures 2 are electrically connected through the first conductive plate 31, forming a loop electrically connected to the anti-misoperation interlocking circuit. With this configuration, when the fixed panel 1, conductive structure 2 and connecting structure 3 are connected to form a double isolation pressure plate for comprehensive anti-misoperation relay protection, or when they are separated, the relay protection circuit and the anti-misoperation interlocking circuit will close or open simultaneously. The on / off state of the anti-misoperation interlocking circuit can remind the operator of the on / off state of the relay protection circuit, thereby ensuring that the relay protection circuit remains connected when the circuit is closed, ensuring the normal function of the relay protection while avoiding misoperation.

[0029] It should be noted that the double-gang isolation pressure plate for relay protection used in this utility model for comprehensive anti-misoperation maintains the basic appearance of the original protection hard pressure plate, is suitable for the original operation habits of maintenance personnel, and retains the neat layout of the original relay protection panel. It can be upgraded without drilling, and the original device can be modified to facilitate the implementation of comprehensive anti-misoperation functions. At the same time, the original relay protection functions and trip output electrical circuits remain unchanged. The double-gang design consists of an inner connection (one path on the first conductive plate 31) and an outer connection (one path on the second conductive plate 32). One connection (inner connection) is used for the original relay protection functions and trip electrical outputs, while the second connection (outer connection) is used for the comprehensive anti-misoperation sensing protection pressure plate status interlocking. Simultaneously, the DC power supply for the anti-misoperation interlocking circuit is taken from the lower end of the secondary control power supply of the outgoing line operation. That is, when the operating power is supplied to the outgoing line, the relay protection power supply should also be supplied simultaneously, the protection circuit starts working, and the anti-misoperation interlocking circuit... The normal operation indicator light illuminates. Specifically, the circuit breaker closing circuit is connected in series with the relay protection output pressure plate (two-way connection), activating the secondary anti-misoperation interlocking relay. The normally closed contact of the secondary anti-misoperation interlocking relay disconnects the starting circuit of the circuit breaker closing circuit interlocking relay. The normally closed contact connected in series with the circuit breaker closing circuit does not operate, and the circuit breaker closing circuit remains intact. However, if the relay protection trip output pressure plate is not engaged, the secondary anti-misoperation interlocking relay, due to the simultaneous disconnection of the two-way connection connected in series with the relay protection output pressure plate, does not operate. Its normally closed contact closes, activating the circuit breaker closing circuit interlocking relay. The normally closed contact connected in series with the circuit breaker closing circuit opens, and the circuit breaker closing circuit is not connected, preventing closing. Simultaneously, when the protection output trip pressure plate is engaged, the integrated anti-misoperation system simultaneously senses the engagement of the pressure plate, closing its normally closed contact and connecting the circuit breaker closing circuit contacts, thus fulfilling the closing conditions and not affecting the normal operation of the closing circuit. Furthermore, no other modifications are made to the circuit breaker and protection trip circuits. When the protection outlet trip pressure plate is out of operation, the normally closed contact of the secondary anti-misoperation interlocking relay starts the circuit breaker closing interlocking relay. Its normally closed contact opens, the circuit breaker closing circuit contact is disconnected, and the circuit breaker cannot be closed.

[0030] Optionally, the connection structure 3 further includes an insulating plate 33, and the first conductive plate 31, the insulating plate 33 and the second conductive plate 32 are stacked in sequence. The end of the conductive rod 21 passes through the first conductive plate 31 and the insulating plate 33 to be electrically connected to the second conductive plate 32.

[0031] Specifically, insulating plate 33 is an insulating sheet.

[0032] In this optional embodiment, to ensure that the first conductive plate 31 and the second conductive plate 32 do not interfere with each other, such as Figure 1As shown, the connection structure 3 is also provided with an insulating plate 33. The first conductive plate 31, the insulating plate 33, and the second conductive plate 32 are stacked sequentially, thereby isolating the first conductive plate 31 and the second conductive plate 32 through the insulating plate 33, ensuring that the first conductive plate 31 and the second conductive plate 32 do not affect each other, and thus ensuring the stability of the relay protection circuit and the anti-misoperation interlocking circuit. On this basis, the end of the conductive rod 21 passes through the first conductive plate 31 and the insulating plate 33 to be electrically connected to the second conductive plate 32. With this arrangement, the end of the conductive rod 21 does not affect the first conductive plate 31, and is stably connected to the second conductive plate 32. This ensures that the relay protection circuit and the anti-misoperation interlocking circuit do not affect each other, and also ensures the normal operation of the relay protection circuit.

[0033] Optionally, the conductive structure 2 further includes a fixing component 24, which is placed on the side of the second conductive plate 32 away from the insulating plate 33 and abuts against the second conductive plate 32 to cooperate with the conductive cylinder 23 to clamp the connecting structure 3. The end of the conductive rod 21 passes through the second conductive plate 32 and is detachably electrically connected to the fixing component 24.

[0034] In this optional embodiment, such as Figure 1 and Figure 2 As shown, to ensure the structural stability of the entire double-gang isolation pressure plate for integrated anti-misoperation relay protection, the conductive structure 2 is also equipped with a fixing component 24. The fixing component 24 is placed on the side of the second conductive plate 32 away from the insulating plate 33 and abuts against the second conductive plate 32. Since the conductive cylinder 23 abuts against the first conductive plate 31, and the first conductive plate 31, the insulating plate 33, and the second conductive plate 32 are stacked in sequence, the fixing component 24 can cooperate with the conductive cylinder 23 to clamp the connecting structure 3. At the same time, the end of the conductive rod 21 passes through the second conductive plate 32 and is detachably electrically connected to the fixing component 24. This arrangement can ensure the stability of the fixing component 24 in clamping the connecting structure 3 with the conductive cylinder 23, thereby ensuring the structural stability of the entire double-gang isolation pressure plate for integrated anti-misoperation relay protection. It can also facilitate the installation and removal of the entire double-gang isolation pressure plate for integrated anti-misoperation relay protection by disassembling the fixing component 24.

[0035] Optionally, the first conductive plate 31, the insulating plate 33, and the second conductive plate 32 are stacked sequentially to form a sandwich plate. A through hole 34 and a notch 35 are provided through the sandwich plate. The through hole 34 is used for the conductive rod 21 of one conductive structure 2 to pass through, and the notch 35 is located at the edge of the sandwich plate and is used for the conductive rod 21 of another conductive structure 2 to be inserted.

[0036] In this optional embodiment, to improve the convenience of synchronous switching of the relay protection circuit and the anti-misoperation interlocking circuit, such as... Figures 1 to 3As shown, the first conductive plate 31, the insulating plate 33, and the second conductive plate 32 are stacked sequentially to form a sandwich panel. A through hole 34 and a notch 35 are provided through the sandwich panel. At this time, the through hole 34 allows the conductive rod 21 of one conductive structure 2 to pass through, while the notch 35 is located at the edge of the sandwich panel and allows the conductive rod 21 of another conductive structure 2 to be inserted. With this configuration, when the relay protection circuit and the anti-misoperation interlocking circuit are simultaneously disconnected, it is only necessary to loosen the fixing component 24 from the conductive rod 21 a little, so that the fixing component 24 is no longer clamping the sandwich panel with the conductive cylinder 23. At this time, force can be applied to drive the side of the sandwich panel with the notch 35 to rotate around the side with the through hole 34 around the conductive rod 21 in the through hole 34, so that the conductive rod 21 in the notch 35 is disengaged from the notch 35, thus realizing the simultaneous disconnection of the relay protection circuit and the anti-misoperation interlocking circuit. Correspondingly, it is only necessary to rotate the sandwich panel in the opposite direction and make the fixing component 24 press the sandwich panel to realize the simultaneous connection of the relay protection circuit and the anti-misoperation interlocking circuit.

[0037] Optionally, the fixing component 24 includes a conductive bolt 241, the end of the conductive rod 21 is provided with an external thread, and passes through the second conductive plate 32 and is screwed into the conductive bolt 241, with the conductive bolt 241 abutting against the second conductive plate 32.

[0038] In this optional embodiment, in order to ensure the installation stability of the connection structure 3, such as Figure 1 and Figure 2 As shown, the fixing component 24 is provided with a conductive bolt 241. The end of the conductive rod 21 is provided with an external thread, and it passes through the second conductive plate 32 and is screwed into the conductive bolt 241. With this configuration, the conductive bolt 241 can be abutted or separated from the second conductive plate 32 by rotating the conductive bolt 241, which can ensure the installation stability of the connection structure 3 and realize the connection stability of the relay protection circuit.

[0039] Optionally, the fixing component 24 also includes an insulating nut 242, which is fitted onto the conductive bolt 241, with the inner wall of the insulating nut 242 fitting against the outer wall of the conductive bolt 241.

[0040] In this optional embodiment, to ensure installation safety, such as Figure 1 and Figure 2 As shown, the fixing component 24 is also provided with an insulating nut 242, which is fitted onto the conductive bolt 241. The inner wall of the insulating nut 242 is in contact with the outer wall of the conductive bolt 241. With this arrangement, when the relay protection circuit and the anti-misoperation interlocking circuit are connected simultaneously, the insulating nut 242 isolates the conductive bolt 241, preventing the conductive bolt 241 from discharging and affecting safety. At the same time, through the mutual friction between the inner wall of the insulating nut 242 and the outer wall of the conductive bolt 241, the conductive bolt 241 can be driven to rotate by applying force to rotate the insulating nut 242, so as to achieve safe installation and removal of the fixing component 24.

[0041] Optionally, the conductive structure 2 further includes a first mounting component 25 and a second mounting component 26. The first mounting component 25 is fitted onto the end of the conductive rod 21 that is away from the connecting structure 3 and abuts against the first insulating cylinder 22. The first mounting component 25 and the conductive rod 21 cooperate to connect to the access end of the relay protection circuit. The second mounting component 26 is fitted onto the end of the first insulating cylinder 22 that is away from the connecting structure 3 and cooperates with the end of the conductive cylinder 23 to connect to the access end of the anti-misoperation interlocking circuit.

[0042] In this optional embodiment, to ensure the stability of the connection of the relay protection circuit and the anti-misoperation interlocking circuit, such as Figure 1 and Figure 2 As shown, the conductive structure 2 is further provided with a first mounting component 25 and a second mounting component 26. The first mounting component 25 is fitted onto the end of the conductive rod 21 away from the connecting structure 3 and abuts against the first insulating cylinder 22, thereby facilitating the fixing of the lead wire of the relay protection circuit connected to the conductive rod 21 and realizing the stable connection of the relay protection circuit. On this basis, the second mounting component 26 is fitted onto the end of the first insulating cylinder 22 away from the connecting structure 3 and cooperates with the end of the conductive cylinder 23 to connect to the access end of the anti-misoperation interlocking circuit, thereby facilitating the fixing of the lead wire of the anti-misoperation interlocking circuit connected to the end of the conductive cylinder 23 and realizing the stable connection of the anti-misoperation interlocking circuit. At the same time, the first mounting component 25 and the second mounting component 26 are isolated from each other by the first insulating cylinder 22 to ensure the stability of current transmission.

[0043] Optionally, the first mounting assembly 25 includes a conductive nut 251 and an anti-loosening spring washer 252, and the second mounting assembly 26 includes an insulating pad 261 and a conductive flat washer 262. The conductive flat washer 262 and the insulating pad 261 are sequentially mounted on the first insulating cylinder 22. The conductive flat washer 262 abuts against the end of the conductive cylinder 23. The anti-loosening spring washer 252 and the conductive nut 251 are sequentially mounted on the conductive rod 21. The anti-loosening spring washer 252 abuts against both the end of the first insulating cylinder 22 and the insulating pad 261. The conductive nut 251 abuts against the anti-loosening spring washer 252. The internal thread of the conductive nut 251 engages with the external thread on the end of the conductive rod 21 away from the connecting structure 3.

[0044] In this optional embodiment, in order to ensure the installation stability of the first mounting component 25 and the second mounting component 26, such as Figure 1 and Figure 2As shown, a first mounting assembly 25 is formed by a conductive nut 251 and an anti-loosening spring washer 252, and a second mounting assembly 26 is formed by an insulating pad 261 and a conductive flat washer 262. The conductive flat washer 262 and the insulating pad 261 are sequentially fitted onto the first insulating cylinder 22, with the conductive flat washer 262 abutting against the end of the conductive cylinder 23, thus facilitating the clamping of the lead wire of the anti-misoperation interlocking circuit. The anti-loosening spring washer 252 and the conductive nut 251 are sequentially fitted onto the conductive rod 21, with the anti-loosening spring washer 252 abutting against both the end of the first insulating cylinder 22 and the insulating pad 261, thereby ensuring the first mounting assembly 25 and the second mounting assembly 26 are properly connected. The two mounting components 26 are isolated from each other. At the same time, the conductive nut 251 abuts against the anti-loosening spring washer 252. The internal thread of the conductive nut 251 engages with the external thread on the end of the conductive rod 21 away from the connecting structure 3. With this arrangement, the lead wire of the relay protection circuit can be clamped by the cooperation of the conductive nut 251 and the anti-loosening spring washer 252. Also, the thread engagement between the conductive nut 251 and the conductive rod 21 allows the conductive nut 251 and the first insulating cylinder 22 to clamp the anti-loosening spring washer 252, the insulating pad 261 and the conductive flat washer 262, ensuring the connection stability of the anti-misoperation interlocking circuit and the relay protection circuit.

[0045] Optionally, the conductive structure 2 further includes a second insulating cylinder 27 and an insulating fixing nut 28. The second insulating cylinder 27 is fitted onto the conductive cylinder 23 and penetrates the fixing panel 1. The diameter of the portion of the second insulating cylinder 27 on the fixing panel 1 facing the connecting structure 3 is larger than the diameter of the portion of the second insulating cylinder 27 inside the fixing panel 1. The diameter of the portion of the second insulating cylinder 27 inside the fixing panel 1 is equal to the diameter of the portion of the second insulating cylinder 27 on the fixing panel 1 away from the connecting structure 3. The insulating fixing nut 28 is located on the side of the fixing panel 1 away from the connecting structure 3 and is fitted onto the second insulating cylinder 27 to abut against the fixing panel 1.

[0046] In this optional embodiment, to ensure operational safety, such as Figure 1 and Figure 2As shown, the conductive structure 2 is further provided with a second insulating cylinder 27 and an insulating fixing nut 28. The second insulating cylinder 27 is fitted onto the conductive cylinder 23 and penetrates the fixed panel 1. The diameter of the portion of the second insulating cylinder 27 on the side of the fixed panel 1 facing the connecting structure 3 is larger than the diameter of the portion of the second insulating cylinder 27 inside the fixed panel 1. The diameter of the portion of the second insulating cylinder 27 inside the fixed panel 1 is equal to the diameter of the portion of the second insulating cylinder 27 on the side of the fixed panel 1 away from the connecting structure 3. Thus, when the second insulating cylinder 27 penetrates the fixed panel 1, the step on the side wall of the second insulating cylinder 27 ensures that the second insulating cylinder 27 is installed in place, thereby ensuring that the conductive structure 2 is installed in place. At the same time, the insulating fixing nut 28 is located on the side of the fixed panel 1 away from the connecting structure 3 and is fitted onto the second insulating cylinder 27 to abut against the fixed panel 1. Thus, the cooperation between the insulating fixing nut 28 and the second insulating cylinder 27 ensures the stable installation of the entire conductive structure 2 on the fixed panel 1, achieving insulation coverage of the entire conductive structure 2 and ensuring operational safety.

[0047] Optionally, the connection structure 3 further includes an insulating button 36, which covers the middle section of the sandwich panel formed by the sequential stacking of the first conductive plate 31, the insulating plate 33, and the second conductive plate 32.
