Description

Technical Field

[0001] This disclosure relates to the field of power grid anti-misoperation interlocking system technology, and in particular to an integrated device for a power grid anti-misoperation interlocking system compatible with multiple communication interfaces. Background Technology

[0002] Anti-misoperation interlocking systems are key safety devices in power systems to prevent misoperation. They can be used in power supply systems such as 750 kV and above AC transmission, large-scale power grid security and defense systems, and intelligent dispatching systems. The core function is to achieve "five protections" (anti-misoperation, anti-maloperation, and anti-maloperation) to avoid personal injury and equipment accidents. They are mainly divided into two types: microcomputer-based anti-misoperation interlocking systems and electrical anti-misoperation interlocking systems. Working together to ensure safety, they consist of: an anti-misoperation host, a computer key, a remote interlocking control unit, and mechanical / electrical coded locks. Through computer pre-operation simulation and logical judgment, intelligent interlocking is achieved. For example, some patents use facial recognition + random password for unlocking to prevent unauthorized operations.

[0003] In existing technologies, anti-misoperation interlocking systems typically lock isolation switches one-to-one. Various unlocking codes are customized through decentralized control, distributed control, DCS, supervisory control and data acquisition systems, data acquisition and control systems, instrument data acquisition, and IoT data acquisition. When unlocking, the host computer needs to use a computer key to select the corresponding isolation switch to lock and unlock. However, it is difficult to achieve unified locking and unlocking control for devices connected to multiple communication interfaces. Summary of the Invention

The two moving blocks at one end of the locking box are threaded onto the surface of the bidirectional screw, and the two moving blocks at the other end of the locking box are slidably mounted onto the slide rod. A motor is fixed to the locking box at the position corresponding to one end of the bidirectional screw, and the output end of the motor is fixedly connected to the bidirectional screw.

[0010] Optionally, the locking assembly further includes: a telescopic column, a base frame, a sliding plate, a lower rod, and an arc plate. The bottom of the square frame is provided with a base frame, and the lower rods are fixed at equal intervals on both sides of the base frame. The lower rods are slidably inserted into the bottom of both sides of the square frame. The bottom of the rotating seat is fixed with a telescopic column, and a first electric push rod is fixed to the extended end of the telescopic column.

[0015] Optionally, an identification chip is installed inside the unlocking slot. The identification chip inside the unlocking slot is inserted into the computer key for identification and unlocking. The computer key also includes a sensing module, a control module, and a wireless transmission module.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. This invention uses a motor to drive a bidirectional screw to rotate. The moving block moves along the moving notch in a threaded engagement with the bidirectional screw, causing the connecting frame to move laterally. The insert plate is inserted into the arc groove of the square plate, causing the locking shaft to extend and retract along the inside of the locking box, thereby inserting into the socket of the disconnect switch and locking the disconnect switch. The second electric push rod drives the connecting frame to descend and ascend, so that the two ends of the connecting frame slide along the vertical frame through the clip frame, maintaining the connection between the connecting frame and the moving block. Thus, the connecting frame and the insert plate can move laterally and vertically, adjusting the position of the locking shaft, and can achieve synchronous locking and opening of all disconnect switches on both sides.

[0018] 2. In this invention, after the disconnector switch is rotated, one of the holes on the disc corresponds to the locking shaft. When the switch is rotated to the other side, the other hole on the disc continues to correspond to the locking shaft. After the locking shaft is inserted into the hole on the disc, the disconnector switch can be locked after being closed or opened.

[0019] 3. The present invention allows the slider to be manually pushed to move along the inside of the frame, thereby adjusting the position of the slider to correspond to the isolation switches in different lateral positions. After the rotating seat rotates, the first electric push rod at the bottom can drive one end of the arc plate toward one side of the isolation switch, thereby allowing for individual adjustment and control of the isolation switch that needs to be unlocked.

[0020] 4. When the second electric push rod drives the connecting frame to descend, the first toothed plate meshes with the gear, and the gear rotates and meshes with the second toothed plate, causing the bottom frame to move vertically. The lower rod passes into the inside of the square frame, and the extended end of the telescopic column retracts, moving the first electric push rod upward. After the first electric push rod rotates towards the lock shaft side, the arc plate can be inserted into the inside of the arc groove. Thus, the first electric push rod pushes the square plate and the lock shaft to move laterally, thereby unlocking a single isolating switch without affecting the locking of other isolating switches. At the same time, because of the connection between the upper and lower rods, when the lower rod moves upward, the upper rod drives the pressure plate to move upward, which facilitates the release of the squeezing limit on the slider.

[0021] 5. As the slider moves along the inside of the frame, the baffles at both ends move along the top opening of the frame and through the through slot. The baffles are automatically wound and unwound by the torsion springs of the two sets of winding seats. The movement of the baffles and the slider seals the opening of the frame, preventing dust from entering the interior of the locking box.

[0038] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown in the figure, this disclosure proposes an integrated device for a power anti-misoperation interlocking system compatible with multiple communication interfaces, including: the power anti-misoperation interlocking system includes a host, a computer key, and an interlocking box 3; a mounting plate 1 is fixed to the bottom of the interlocking box 3, and four sets of disconnecting switches 2 are equidistantly fixed on both sides of the interlocking box 3 on the mounting plate 1, with knife switches 21 rotatably mounted on the surface of the disconnecting switches 2; a square frame 41 is fixed to the top of the interlocking box 3, and a locking component 4 is slidably installed inside the square frame 41; locking shafts 31 are slidably inserted into both sides of the interlocking box 3 corresponding to the positions of the disconnecting switches 2, and the locking shafts 31 pass through the interlocking box 3 and are locked to the disconnecting switches 2; drive components 5 are provided inside the interlocking box 3 on both sides of the square frame 41; the locking component 4 includes a slider 45, which is slidably installed inside the square frame 41, and a rotating seat 46 is rotatably installed inside the slider 45. The top of the seat 46 is provided with an unlocking slot 47, and the bottom of the rotating seat 46 is equipped with a first electric push rod 49. The drive assembly 5 includes a connecting frame 58, which is provided in two sets. The two sets of connecting frames 58 are slidably inserted into the rear end of the locking shaft 31. The two ends of the connecting frame 58 are fixed with second electric push rods 57, and the top of the second electric push rods 57 is slidably installed on the top inner wall of the locking box 3. When using the device, each disconnect switch 2 is connected to the device through a communication interface via a connecting line. The drive assembly 5 can lock all disconnect switches 2 simultaneously. When it is necessary to unlock a disconnect switch 2 for maintenance, the host generates a corresponding unlocking code. The computer key carrying the unlocking code is inserted into the unlocking slot 47 for identification. Then the locking assembly 4 moves to the position of the corresponding disconnect switch 2 and unlocks the specified disconnect switch 2 without interfering with or affecting the other disconnect switches 2.

[0040] like Figure 2As shown, in some embodiments, a disc 22 is rotatably mounted on one side of the disconnect switch 2. The disc 22 is fixedly connected to the rotating shaft of the knife switch 21. Two insertion holes 23 are provided on the disc 22. The locking shaft 31 of the locking box 3 is inserted into one of the insertion holes 23 of the disc 22. The included angle between the two insertion holes 23 is the same as the included angle of the knife switch 21 as it moves from the disconnect switch 2 to the other end.

[0041] It is understandable that after the knife switch 21 of the disconnecting switch 2 rotates, one of the sockets 23 on the disc 22 corresponds to the locking shaft 31. When the knife switch 21 rotates to the other side, the other socket 23 on the disc 22 continues to correspond to the locking shaft 31. After the locking shaft 31 is inserted into the socket 23 of the disc 22, the knife switch 21 of the disconnecting switch 2 can be locked after being closed or opened.

[0042] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, a square plate 32 is fixed to one end of the locking shaft 31 inside the locking box 3, and a first spring 33 is sleeved on the surface of the locking shaft 31. The two ends of the first spring 33 are fixedly connected to the inner wall of the locking box 3 and the square plate 32. An arc groove 35 is formed at the bottom of the square plate 32. The connecting frame 58 is fixed with an insert plate 56 at the position of the arc groove 35, and the insert plate 56 is slidably inserted into the arc groove 35. The driving assembly 5 also includes: a bidirectional screw 51, a motor 52, a moving block 53, a moving notch 54, and a slide rod 55. One end of the locking box 3 A bidirectional screw 51 is rotatably mounted, and a slide rod 55 is fixed at the other end of the locking box 3. The locking box 3 has a movable notch 54 corresponding to the positions of the bidirectional screw 51 and the slide rod 55. Two movable blocks 53 slide through the movable notch 54. The two movable blocks 53 at one end of the locking box 3 are threaded onto the surface of the bidirectional screw 51, and the two movable blocks 53 at the other end of the locking box 3 are slidably fitted onto the slide rod 55. A motor 52 is fixed at one end of the locking box 3 corresponding to the position of the bidirectional screw 51, and the output end of the motor 52 is fixedly connected to the bidirectional screw 51.

[0043] Understandably, motor 52 drives bidirectional screw 51 to rotate, and moving block 53 moves along moving notch 54 with threaded engagement with bidirectional screw 51, driving connecting frame 58 to move laterally. Insert plate 56 is inserted into arc groove 35 of square plate 32, causing locking shaft 31 to extend and retract along the inside of locking box 3, thereby inserting into socket 23 of disconnect switch 2 to lock disconnect switch 2. The second electric push rod 57 drives connecting frame 58 to descend and ascend, so that both ends of connecting frame 58 slide along vertical frame 510 through clip frame 59, maintaining connection between connecting frame 58 and moving block 53. Thus, connecting frame 58 and insert plate 56 can move laterally and vertically, adjusting the position of locking shaft 31, and can realize the synchronous locking and unlocking of all disconnect switches 2 on both sides. This part works in conjunction with the individual unlocking of disconnect switch 2 of locking component 4 to realize distributed control of multiple sets of disconnect switches 2.

[0044] like Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the locking assembly 4 further includes: a telescopic column 48, a bottom frame 410, a sliding plate 411, a lower rod 412, and an arc plate 413. The bottom of the square frame 41 is provided with a bottom frame 410, and the lower rods 412 are fixed at equal intervals on both sides of the bottom frame 410. The lower rods 412 are slidably inserted into the bottom of both sides of the square frame 41. The bottom of the rotating seat 46 is fixed with a telescopic column 48, and the first electric push rod 49 is fixed to the extended end of the telescopic column 48. The sliding plate 411 is slidably connected inside the bottom frame 410, and the bottom of the telescopic column 48 is rotatably mounted on the sliding plate 411. The extended end of the first electric push rod 49 is fixed with an arc plate 413, and the arc plate 413 matches the shape of the arc groove 35 at the bottom of the square plate 32. The moving block 53 is fixed with a vertical frame 510 on one side inside the locking box 3. A card frame 59 is slidably sleeved on the surface of the vertical frame 510, and the card frame 59 is fixedly connected to the connecting frame 58.

[0045] It should be noted that by manually pushing the slider 45 along the inside of the frame 41, the position of the slider 45 can be adjusted to correspond to the isolation switches 2 in different horizontal positions. After the rotating seat 46 rotates, the bottom first electric push rod 49 can drive one end of the arc plate 413 toward one side of the isolation switch 2, thereby allowing for individual adjustment and control of the isolation switch 2 that needs to be unlocked.

[0046] like Figure 4 , Figure 7 and Figure 8As shown, in some embodiments, pressure plates 42 are provided on both sides of the top of the frame 41, and upper rods 43 are fixed at equal intervals on both sides of the pressure plates 42, and the upper rods 43 are slidably inserted into the interior of both sides of the frame 41; wherein, the upper rods 43 are fixedly connected to the lower rods 412, the pressure plates 42 are in contact with the top of both sides of the slider 45, and a gear 511 is provided between the connecting frame 58 and the bottom frame 410. The gear 511 is rotatably installed inside the locking box 3 through a rotating frame, and a first toothed plate 512 is meshed on one side of the gear 511, and a second toothed plate 513 is meshed on the other side of the gear 511; wherein, the first toothed plate 512 is fixedly connected to the connecting frame 58, and the second toothed plate 513 is fixedly connected to the bottom frame 410.

[0047] It should be noted that when the second electric push rod 57 drives the connecting frame 58 to descend, the first toothed plate 512 meshes with the gear 511. The gear 511 rotates and meshes with the second toothed plate 513, causing the bottom frame 410 to move vertically. The lower rod 412 passes into the square frame 41, and the extended end of the telescopic column 48 retracts, moving the first electric push rod 49 upward. After the first electric push rod 49 rotates towards the locking shaft 31, the arc plate 413 can be inserted into the arc groove 35. Thus, the first electric push rod 49 pushes the square plate 32 and the locking shaft 31 to move laterally, thereby unlocking one isolation switch 2 independently without affecting the locking of other isolation switches 2. At the same time, due to the connection between the upper rod 43 and the lower rod 412, when the lower rod 412 moves upward, the upper rod 43 drives the pressure plate 42 to move upward, which facilitates the release of the squeezing limit on the slider 45.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the locking box 3 is fixed with a winding seat 44 at both ends, and the winding seat 44 is wound with a baffle cloth by a torsion spring and a winding shaft. The baffle cloth of the winding seat 44 passes through the top of the square frame 41 and is fixedly connected to both sides of the slider 45. The square frame 41 and the locking box 3 are provided with through slots 34 at the positions where the baffle cloth passes through.

[0049] It should be noted that as the slider 45 moves along the inside of the frame 41, the baffles at both ends move along the top opening of the frame 41 and move through the through slot 34. They are automatically wound and unwound by the torsion springs of the two sets of winding seats 44. The movement of the baffles and the slider 45 seals the opening of the frame 41, preventing dust from entering the interior of the locking box 3.

[0050] In some embodiments, an identification chip is installed inside the unlocking slot 47. The identification chip inside the unlocking slot 47 is inserted into the computer key for identification and unlocking. The computer key also includes a sensing module, a control module, and a wireless transmission module. The control module includes a receiving module for receiving signals sent by the terminal processor. The terminal processor can be a computer. This system utilizes a supervisory control and data acquisition system, a data acquisition and control system, instrument data acquisition, and IoT data acquisition. This system typically employs a three-layer architecture: a station control layer, an interval layer, and a process layer, with each layer working collaboratively.

[0051] Station Control Layer: Composed of anti-misoperation host units, responsible for storing the substation's primary wiring diagram, equipment operating rules, and interlocking logic database. It communicates with the monitoring system in real time, obtains equipment status information, and performs simulations and logical judgments on operation tickets.

[0052] Interval Layer: Composed of computer keys or smart keys, serving as the operator's tool. It receives unlocking commands from the anti-misoperation host and performs unlocking operations on the equipment on-site, while simultaneously transmitting equipment status information back in real time.

[0053] Process layer: Consists of locks installed on electrical equipment, including mechanical coded locks and electrical coded locks, used for physical locking of equipment such as circuit breakers, disconnect switches, and grounding switches.

[0054] The system's workflow can be summarized as follows:

[0055] Simulation and rehearsal: Operators simulate operation tickets on the error prevention host. The system judges the operation based on the interlocking logic database to ensure the safety and accuracy of the operation steps.

[0056] Generate and issue commands: After the simulation is successful, the host computer generates the actual operating procedure and issues the unlock command to the computer key and the remote locking controller.

[0057] On-site operation and status feedback: Operators bring a computer key to the site, unlock the equipment according to instructions, and operate it. The computer key feeds back the equipment status to the host in real time, achieving alignment between the system and the on-site equipment.

[0058] By using this "software logic judgment + hardware forced interlocking" approach, the system ensures the uniqueness and sequence of operations, effectively preventing five typical erroneous operations in the power system.

[0059] Working principle:

[0060] When using the device, each disconnect switch 2 is connected to the equipment via a communication interface through a connecting cable. Motor 52 drives bidirectional screw 51 to rotate. Moving block 53, threadedly engaged with bidirectional screw 51, moves along moving notch 54, causing connecting frame 58 to move laterally. Insert plate 56 is inserted into the arc groove 35 of square plate 32, causing locking shaft 31 to extend and retract along the inside of locking box 3, thus inserting into the socket 23 of disconnect switch 2 to lock it. Second electric push rod 57 drives connecting frame 58 to descend and ascend, allowing both ends of connecting frame 58 to slide along vertical frame 510 via clip frame 59, maintaining the connection between connecting frame 58 and moving block 53. Thus, connecting frame 58 and insert plate 56 can move laterally and horizontally. Vertical movement adjusts the position of the locking shaft 31, enabling simultaneous locking and unlocking of all isolation switches 2 on both sides. When a single isolation switch 2 needs to be unlocked for maintenance, the host generates a corresponding unlocking code. A computer key carrying the unlocking code is inserted into the unlocking slot 47 for identification. Manually pushing the slider 45 along the inside of the frame 41 adjusts the position of the slider 45 to correspond to different horizontal positions of the isolation switches 2. After the rotating seat 46 rotates, the first electric push rod 49 at the bottom can drive one end of the arc plate 413 toward one side of the isolation switch 2, thereby allowing for individual adjustment and control of the isolation switch 2 that needs to be unlocked. When the second electric push rod 57 drives the connecting frame 58 to descend, the first... The toothed plate 512 meshes with the gear 511. The rotation of the gear 511 meshes with the second toothed plate 513, causing the bottom frame 410 to move vertically. The lower rod 412 passes into the square frame 41, and the extended end of the telescopic column 48 retracts, moving the first electric push rod 49 upward. After the first electric push rod 49 rotates towards the locking shaft 31, the arc plate 413 can be inserted into the arc groove 35. Thus, the first electric push rod 49 pushes the square plate 32 and the locking shaft 31 to move laterally, thereby unlocking one disconnect switch 2 independently without affecting the locking of other disconnect switches 2. At the same time, because of the connection between the upper rod 43 and the lower rod 412, when the lower rod 412 moves upward, the upper rod 43 drives the pressure plate 42 to move upward, facilitating... Release the squeezing limit on slider 45. As slider 45 moves inside frame 41, the baffles at both ends move along the top opening of frame 41 and through slot 34. The torsion springs of two sets of winding seats 44 automatically wind and unwind the blocks. The movement of baffles and slider 45 seals the opening of frame 41, preventing dust from entering the interior of locking box 3.
