Description

Technical Field

[0001] The present invention relates to the technical field of relay protection, and in particular to a device and method for preventing erroneous operation of a relay protection terminal block. Background Art

[0002] Terminal blocks in substation relay protection cabinets have numerous connections at both ends, necessitating extensive manipulation during overhauls, technical upgrades, and pre-testing. Further reducing the risk of operators accidentally touching or disconnecting terminal block connections and preventing them from illegally manipulating them is crucial for power grid safety.

[0003] At present, the common method of using insulating tape to block and insulating plastic buckles to seal in substations to avoid the above accidents is to avoid accidents, which has great safety hazards:

[0004] 1. The insulating tape is directly pasted on the terminal block, which can easily cause damage to the terminal block during pasting and tearing. At the same time, the insulating tape has weak wrapping properties and is easy to fall off, and the pasting range cannot cover the wiring on both sides of the terminal block.

[0005] 2. The insulating plastic clips are directly installed on the terminal block, which requires frequent disassembly and assembly during operation, which can easily cause the terminal block interface to become loose or even damaged. In addition, it is very easy to accidentally touch the wires at both ends of the terminal block when disassembling and assembling the plastic clips.

[0006] 3. In the existing technology, the covering and blocking of the terminal block are not managed by the background monitoring system, which makes it very easy to make mistakes such as wrong covering or insufficient covering.

[0007] 4. The existing technology has no function to prevent the terminal blocks from being dismantled by mistake, and it is impossible to avoid the risk of operators subjectively removing the anti-misoperation measures and then performing illegal operations.

[0008] The authorization announcement number is CN 211150823 U, and the name is a combination protective device for preventing accidental collision of relay protection terminal blocks. The T-shaped slider slides in the T-shaped slot, and when the terminal needs to be shielded, the required limit block can be clamped in the limit slot. At this time, the insulating protective plates on both sides of the outer wall of the support rod can play an insulating shielding effect; the movable support rod is set between the support rod and the side plate, and locked and fixed by tightening bolts, so that the overall structure tends to be stable; it effectively avoids misconnection of terminals or accidental collisions between terminals, reducing safety hazards. It can effectively isolate the terminals and play the role of insulating shielding, thereby avoiding accidental collisions of terminals and reducing safety hazards. However, since personnel still need to touch the operating protective device, the operating efficiency is still poor, because personnel still need to be very careful during operation to avoid accidentally touching adjacent terminals.

[0009] The authorization announcement number is CN 206992370 U, and the name is "Terminal Block Anti-Inadvertent Touch Protection Combined Protective Gear." It can effectively protect a single or multiple terminals on a terminal block. It is very convenient to install or remove, and facilitates wiring or disconnecting operations on the terminal block. It effectively prevents accidents such as accidental contact and dropped screws during operation, thereby preventing equipment damage. However, because personnel still need to touch the protective device to operate it, the operational efficiency is still poor. This is because personnel still need to be very careful during operation to avoid accidentally touching adjacent terminals.

[0010] Existing technical problems and considerations:

[0011] 1. The existing anti-misoperation work is to directly operate the terminal block, which is easy to cause damage to the terminal block.

[0012] 2. The existing anti-misoperation work is not managed by the background monitoring system, and blocking errors are very likely to occur.

[0013] 3. The existing anti-misoperation system has no anti-dismantling function, and there is a risk that operators may subjectively remove obstructions and blockages and then perform illegal operations. Summary of the Invention

[0099] The concept of this application:

[0100] 1. The present invention relates to a device and method for preventing misoperation of a relay protection terminal block. The prior art generally adopts a method of directly installing an anti-misoperation tool on the terminal block to prevent accidental touching or removal of the wiring at both ends of the terminal block. However, although the anti-misoperation tool directly installed on the terminal block can shield the terminal block, it is also easy to cause damage to the terminal block during the disassembly process. The inventors have discovered that by directly installing and fixing the relay protection anti-misoperation device on the outside of the terminal block without any structural connection to the terminal block, the anti-misoperation function can be achieved without causing damage to the terminal block. Therefore, the inventive concept of this case is to use an anti-misoperation device installed on the outside of the terminal block.

[0101] 2. The present invention relates to a device and method for preventing misoperation of a relay protection terminal block. The prior art generally adopts a method in which operators directly perform misoperation prevention work on the terminal block according to their work tasks. However, there is a risk of incorrect or insufficient coverage when operators directly perform misoperation prevention. The inventors have discovered that a method of directly sending unlockable terminal block numbers to the anti-misoperation device through the background monitoring system can avoid the risks caused by insufficient operator skills or operational errors. Therefore, the inventive concept of this case is that the background monitoring system command receiving and processing functions of the device for preventing misoperation of the relay protection terminal block invented in this case can improve the accuracy of the terminal block anti-misoperation work.

[0102] 3. The present invention relates to a device and method for preventing misoperation of a relay protection terminal block. The anti-misoperation method used in the prior art cannot prevent operators from subjectively removing the anti-misoperation baffle. The inventors have discovered that the method of identifying the identity of the operator and mechanically locking the anti-misoperation baffle with a spring electronic lock can reduce the risk of operators subjectively removing the anti-misoperation baffle to perform illegal operations. Therefore, the inventive concept of this case is that, through the identity recognition function and the automatic opening and closing locking baffle function of the device for preventing misoperation of the relay protection terminal block invented in this case, the risk of subjective illegal operations by operators can be reduced, thereby improving the stability of power grid operation.

[0108] like Figure 6 FIG. 1 is a flowchart showing the startup of the terminal block misoperation device according to the present invention.

[0109] like Figure 5 and Figure 6 The method steps are as follows:

[0110] S1 confirms the unlockable terminal strip number

[0111] The S101 communication module receives the terminal block number that can be unlocked for this operation sent by the background monitoring system computer.

[0112] S102: The communication module sends the received unlockable terminal block number to the data processing module.

[0113] S2 confirms the identity of the operator

[0114] S201: The operator inputs an operation password, and the identity recognition module recognizes the password input by the operator.

[0115] S202 After the identity recognition module confirms that the identity of the operator is correct, it sends an unlocking instruction to the data processing module.

[0116] S3 spring electronic lock start

[0117] After receiving the instructions of S102 and S202 at the same time, the data processing module S301 sends the unlockable terminal block number to the control module.

[0118] Unlocking the S302 control module can unlock the spring electronic lock in the corresponding baffle of the terminal block, and the other terminal block baffles remain locked.

[0119] After this application was run confidentially for a period of time, the on-site technicians reported that the following benefits were achieved:

[0120] 1. Reduce the damage to the terminal block caused by anti-misoperation work.

[0121] 2. The anti-misoperation workflow is managed by the background monitoring system, which reduces the error rate of the anti-misoperation work.

[0122] 3. The anti-misoperation work has an anti-dismantling function, which eliminates the risk of operators accidentally touching or dismantling the terminal block wiring and subjective illegal operations, thereby improving the safety of relay protection equipment and the stability of power grid operation.

[0123] The device includes a box body and a controller, a communication device, an identity recognition device, an electronic lock and a terminal block baffle on the box body. The controller is electrically connected to the communication device, the identity recognition device and the electronic lock respectively.

The method includes the following steps: the controller obtains the unlocking terminal block number and obtains the identity information to be verified of the current operator. When the identity information to be verified belongs to an authorized operator, an unlocking instruction is generated and the unlocking instruction and the unlocking terminal block number are sent to the electronic lock. The electronic lock obtains the unlocking instruction and the unlocking terminal block number and unlocks the corresponding terminal block baffle. It avoids misoperation of the relay protection terminal through the controller, the communication device, the identity recognition device, the electronic lock and the terminal block baffle.
