Description

Technical Field

[0001] The present application relates to the technical field of preventing errors in the hanging of high-altitude grounding wires in indoor substations, and in particular to a method and system for preventing errors in the hanging of high-altitude grounding wires. Background Art

[0002] In the operation and maintenance of indoor substations, the problem of temporary grounding wire hanging on the high-voltage side of the transformer is significant. For example, the heavy grounding wire makes the operator face a huge physical burden during the hanging process, affecting the operation efficiency; due to the height of the grounding wire, the operator needs to use various equipment to reach the hanging point, which increases the complexity and risk of the operation; long-term operation not only consumes physical strength, but also prolongs the maintenance time, posing a threat to the normal operation of the power system. Therefore, indoor substations have a narrow space and require operators to manually hang the ground wire, which not only has low operation efficiency but also high operation risks. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a method and system for preventing mis-control of high-altitude ground wire hanging, so as to solve the above-mentioned technical problems.

[0004] In the first aspect, an embodiment of the present application provides a high-altitude grounding wire hanging anti-error control method, the method comprising: a knife switch disconnection step: a computer key obtains an operation sequence from an anti-error host, and executes the disconnection of the circuit breaker switch and the isolation knife switch opening operation related to the main transformer line; an electrical test interlocking step: the main transformer line and the ground wire hanging control box are electrically interlocked, and the intelligent electric tester obtains the electrical test information of the main transformer line. If it is detected that the line is without electricity, the ground wire hanging control box is allowed to be opened. If it is detected that the line is energized, the ground wire hanging control box cannot be opened; a ground wire end hanging step: the intelligent ground wire head is hung with the ground wire pile, and the intelligent ground wire head sends its hanging position and hanging status to the anti-error host, and the anti-error host sends the hanging authority of the ground wire line end and the main transformer line to the ground wire hanging control box; a line end hanging step: log in to the ground wire hanging control box to obtain the hanging authority of the ground wire line end and the main transformer line, operate the ground wire lifting mechanism to raise the ground wire line end close to and clamp the main transformer line, and the ground wire line end sends its hanging status to the anti-error host.

[0005] Before the grounding wire is hooked up, the embodiment of the present application uses an intelligent electric tester to test the line of the main transformer, so as to test and lock the grounding wire hooking control box, and manage the login authority of the grounding wire hooking control box by obtaining the hooking authority of the anti-misoperation host, so as to prevent live grounding and misoperation. In addition, when the grounding wire is hooked up, the grounding wire line end is raised to the hooking position by the grounding wire lifting mechanism, which improves the operation efficiency and reduces the operation risk.

[0008] In some embodiments, the intelligent electrical tester includes a sensor, a display unit and a locking contact; the locking contact is connected in series to the unlocking circuit of the door lock of the ground wire hanging control box. When the main transformer line is energized, the locking contact is disconnected and the door lock cannot be opened. When the main transformer line is without power, the locking contact is connected and the door lock is allowed to be opened.

[0009] In the embodiment of the present application, the electrical interlocking of the intelligent electrometer and the ground wire hooking control box is realized by connecting the locking contact in the intelligent electrometer in series with the unlocking circuit of the box door lock of the ground wire hooking control box. In this process, there is no need to manually judge whether the line is energized. Instead, the intelligent electrometer automatically transmits the test result to the box door lock of the ground wire hooking control box to automatically control the opening of the box door lock, thereby preventing energized operation and reducing operation risks.

[0010] In some embodiments, in the ground wire end hanging step, the method also includes: the anti-error host sends a line end hanging prompt to the ground wire hanging control box; in the line end hanging step, it also includes: the ground wire hanging control box sends a line end hanging application to the anti-error host; after the line end hanging application is approved, the ground wire lifting mechanism performs the line end hanging operation.

[0011] In the embodiment of the present application, before the ground wire is hung, a line end hanging application is sent to the anti-mistake host again. After the hanging application is approved, the ground wire lifting mechanism is operated to hang it, which further improves the operation safety.

[0012] In some embodiments, the main transformer line includes three-phase lines A, B, and C; in the line-end hanging step, the grounding wire lifting mechanism is operated to raise the grounding wire line end close to and clamp the main transformer line, including: sequentially operating the grounding wire lifting mechanism to raise the grounding wire line ends corresponding to the three-phase lines A, B, and C close to and clamp the corresponding main transformer line.

[0013] The embodiment of the present application controls the connection process of the three-phase lines A, B, and C in sequence, so that the connection process of each phase is properly handled, thereby avoiding safety hazards caused by missing a phase and reducing operational risks.

[0015] The embodiment of the present application uses the cooperation between the various devices in the high-altitude ground wire hooking anti-error control system to perform power testing and locking and login authority management on the ground wire hooking control box, thereby preventing live grounding and misoperation. In addition, the ground wire line end is raised to the hooking position through the ground wire lifting mechanism, which improves the operation efficiency and reduces the operation risk.

[0016] In some embodiments, an operating device is provided in the ground wire hooking control box, and the operating device is used to control the rising or falling of the ground wire lifting mechanism and to control the clamping or loosening of the line end of the ground wire.

[0017] The embodiment of the present application realizes remote intelligent control of the ground wire lifting mechanism and the ground wire line end through the operating device in the ground wire hanging control box, thereby reducing the difficulty and operational risks of manually hanging the ground wire.

[0018] In some embodiments, the smart tester includes a sensor, a display unit and a locking contact; the smart tester is electrically interlocked with the ground wire hook control box through the locking contact; the sensor is used to detect the power information of the main transformer line; if the sensor detects that the main transformer line is energized, the locking contact is disconnected, and a live light warning is issued through the display unit; if the sensor detects that the main transformer line has no power, the locking contact is connected to open the door lock of the ground wire hook control box.

[0019] The embodiment of the present application uses the locking contact in the intelligent electroscope to electrically interlock with the door lock of the ground wire hook control box to prevent live operation and reduce the operation risk.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0034] Figure 1 A schematic diagram of a high-altitude ground wire hooking anti-error control system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the system 10 includes an anti-error host 101, a computer key 102, a ground wire hooking control box 103, an intelligent electrometer 104, a ground wire lifting mechanism 105 and an intelligent ground wire 106. The anti-error host 101 is respectively connected to the computer key 102, the ground wire hooking control box 103 and the intelligent ground wire 106. The ground wire hooking control box 103 is electrically interlocked with the intelligent electrometer 104; the ground wire hooking control box 103 is respectively connected to the ground wire lifting mechanism 105 and the intelligent ground wire 106.

[0035] The anti-error host 101 sends an operation sequence to the computer key 102; the intelligent tester 104 is used to obtain the test information of the main transformer line, and transmit the test information to the ground wire hanging control box 103; the intelligent ground wire 106 includes an intelligent ground wire head, a ground wire line end and a ground wire cable for connecting the two; the ground wire hanging control box 103 is used to control the ground wire lifting mechanism 105 to carry the ground wire line end for lifting and lowering, and control the ground wire line end to clamp or release the main transformer line.

[0036] The anti-error host 101 is a terminal device, which can be a smart phone, a tablet computer, a computer, a personal digital assistant (PDA), etc. A microcomputer anti-error locking system is installed in the anti-error host, so that the power equipment maintenance personnel can create maintenance tasks through the microcomputer anti-error locking system, generate operation instructions based on the maintenance tasks, and send the operation instructions to the computer key 102.

[0037] The computer key 102 is a portable terminal device for receiving operation instructions sent by the anti-error host 101. During the operation, the computer key 102 gives operation prompts, and the maintenance personnel follow the prompts of the computer key 102 to perform correct operations step by step.

[0038] The intelligent tester 104 is a device for detecting whether the voltage line and the power equipment are energized. The intelligent tester is installed near the main transformer line to detect the energization of the main transformer line, thereby obtaining the test information of the main transformer line and transmitting the test information to the ground wire hook control box 103.

[0039] The intelligent electrometer may be at least one of a wireless high-voltage electrometer, a high- and low-voltage intelligent electrometer, and a fully intelligent wireless high-voltage electrometer.

[0040] The power test information refers to the detection result of the live condition of the main transformer line. The power test information may be that the main transformer line is live or that the main transformer line is not live.

[0041] The ground wire hooking control box 103 is an operating mechanism for managing the ground wire lifting mechanism 105 and the intelligent ground wire 106. That is, the maintenance personnel control the ground wire lifting mechanism 105 to carry the ground wire line end to lift and lower through the ground wire hooking control box 103, and control the ground wire line end to clamp or release the main transformer line.

[0042] The intelligent ground line 106 includes an intelligent ground line head, a ground line end, and a ground line cable for connecting the two.

[0043] To facilitate the understanding of smart ground, Figure 2 A schematic diagram of an intelligent ground wire connected to a three-phase circuit provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the intelligent ground line includes an intelligent ground line head, three ground line line ends and three ground line cables for connecting the two.

[0044] An intelligent grounding clamp is bound to the line end of the grounding wire, and the intelligent grounding clamp has an electric function and a communication function. The line end of the grounding wire is connected to the grounding wire hooking control box 103 through the communication function of the intelligent grounding clamp, so that the grounding wire hooking control box 103 can remotely control the line end of the grounding wire to clamp or loosen the main transformer line. In addition, the intelligent grounding clamp can also detect the hooking status of the line end of the grounding wire, and send the hooking status to the anti-error host through the communication function.

[0045] In order to facilitate the control of the ground wire lifting mechanism 105 and the intelligent ground wire 106 through the ground wire hanging control box 103 and reduce the difficulty and operation risk of manually hanging the ground wire, an operating device is arranged in the ground wire hanging control box 103. The operating device is used to control the rising or falling of the ground wire lifting mechanism and to control the clamping or loosening of the ground wire line end.

[0046] In some embodiments, the high-altitude ground wire hanging error prevention control system 10 also includes a ground wire pile. Figure 3 A schematic diagram of intelligent ground connection of a three-phase circuit provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the grounding pile is connected to the intelligent grounding head; the intelligent grounding head sends its connection position and connection status to the anti-error host. The three grounding line ends are respectively connected to the corresponding main transformer lines, and their connection status is sent to the anti-error host.

[0047] The embodiment of the present application uses the cooperation between the various devices in the high-altitude ground wire hooking anti-error control system to perform power testing and locking and login authority management on the ground wire hooking control box, thereby preventing live grounding and misoperation. In addition, the ground wire line end is raised to the hooking position through the ground wire lifting mechanism, which improves the operation efficiency and reduces the operation risk.

[0048] In some embodiments, the smart tester includes a sensor, a display unit and a locking contact; the smart tester is electrically interlocked with the ground wire hook control box through the locking contact; the sensor is used to detect the power information of the main transformer line; if the sensor detects that the main transformer line is energized, the locking contact is disconnected, and a live light warning is issued through the display unit; if the sensor detects that the main transformer line has no power, the locking contact is connected to open the door lock of the ground wire hook control box.

[0049] In order to realize the electrical interlocking between the ground wire hooking control box 103 and the intelligent electrometer 104, the intelligent electrometer includes a locking contact.

[0050] Locking contacts refer to additional contacts added to the operating circuit of electrical equipment. These contacts realize mutual locking between devices through electrical circuits to prevent misoperation. Locking contacts achieve the purpose of forced locking by opening and closing the power supply of the controlled equipment. Locking contacts can be normally open or normally closed.

[0051] Electrical interlocking refers to interlocking achieved by electrical means, that is, connections between several electrical appliances or components to ensure that the appliances or their components operate in a specified order or to prevent false operations.

[0052] Therefore, by connecting the locking contact in series to the unlocking circuit of the door lock of the ground wire hanging control box, the intelligent electrometer and the ground wire hanging control box can be electrically interlocked through the locking contact.

[0053] In the embodiment of the present application, when the main transformer line is energized, the locking contact is disconnected and the box door lock cannot be opened. When the main transformer line is de-energized, the locking contact is connected and the box door lock is allowed to be opened. In this process, there is no need to manually determine whether the line is energized. Instead, the intelligent electric tester automatically transmits the test result to the box door lock of the ground wire hanging control box to automatically control the opening of the box door lock, thereby preventing live operation and reducing operation risks.

[0054] Based on the above embodiments, it can be known that the intelligent electrometer is installed near the main transformer. In order to facilitate the detection of the live power of the main transformer line and the alarm prompt, the intelligent electrometer also includes a sensor and a display unit. The sensor detects the live power information of the main transformer line, and if the sensor detects that the main transformer line is live, the locking contact is disconnected, and the live light warning is performed through the display unit; if the sensor detects that the main transformer line is not powered, the locking contact is connected to open the door lock of the ground wire hanging control box.

[0055] Figure 4 A schematic diagram of another high-altitude ground wire hanging anti-error control system provided in an embodiment of the present application, such as Figure 4 As shown, the ground wire hooking control box is respectively connected to the anti-error host, the ground wire lifting mechanism and the intelligent ground wire, and the intelligent tester is electrically interlocked with the ground wire hooking control box. The intelligent tester is installed near the main transformer line, used to detect the main transformer line, and send the detection result to the ground wire hooking control box, the ground wire hooking control box controls the ground wire lifting mechanism to lift and lower, and controls the intelligent ground wire to clamp or release the corresponding main transformer line.

[0056] The embodiment of the present application uses the locking contact in the intelligent electroscope to electrically interlock with the door lock of the ground wire hook control box to prevent live operation and reduce the operation risk. In addition, when the main transformer line is detected to be live, a live light warning is provided through the display unit to improve the warning and thus reduce the operation risk.

[0057] In some embodiments, the grounding wire lifting mechanism includes a motor, a transmission and a lifting rod; the grounding wire line end is installed on the top of the lifting rod; the transmission converts the high-speed rotational motion of the motor into low-speed and high-torque rotation to drive the lifting rod to lift and lower, so that the grounding wire line end rises close to and clamps or releases the main transformer line.

[0058] In the embodiment of the present application, the lifting rod in the ground wire lifting mechanism lifts the top end of the ground wire to a hanging position, thereby reducing the difficulty of manually hanging the ground wire and reducing operational risks.

[0059] In some embodiments, the system further comprises an anti-error adapter; the anti-error host sends an operation sequence to the computer key via the anti-error adapter.

[0060] The anti-error adapter serves as the communication link between the anti-error host and the computer key. It is responsible for transmitting the correct operation content generated by the anti-error host to the computer key. At the same time, after the computer key operation is completed, the operation information can also be transmitted to the anti-error host through the anti-error adapter.

[0061] The anti-mistake adapter can also have the function of intelligently charging the computer key and the function of detecting the presence of the computer key to ensure that the computer key is correctly placed on the adapter for communication and charging.

[0062] It should be noted that the design of the anti-error adapter needs to ensure compatibility with the anti-error host and computer key to ensure the normal operation of the entire anti-error system.

[0063] The embodiment of the present application improves the security and accuracy of sending the operation sequence by providing an anti-error adapter between the anti-error host and the computer key.

[0064] Figure 5 A flowchart of a method for preventing misconnection of a high-altitude ground wire provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the method includes:

[0065] Step S100, knife switch disconnection step: the computer key obtains the operation sequence from the anti-error host, and executes the circuit breaker switch disconnection and isolation knife switch opening operations related to the main transformer line.

[0066] Based on the above embodiments, it can be known that the error-prevention host generates an operation sequence based on the maintenance task, and sends the operation sequence to the computer key, so that the computer key obtains the operation sequence.

[0067] The maintenance personnel perform operations such as disconnecting the circuit breaker and opening the isolating switch related to the main transformer line based on the operation sequence of the computer key, and send the execution results to the anti-error host through the computer key so that the anti-error host can check and confirm the status of the main transformer.

[0068] Step S200, electrical test interlocking step: the main transformer circuit is electrically interlocked with the ground wire hanging control box, the intelligent electrical tester obtains the electrical test information of the main transformer circuit, if it is detected that the circuit is without power, the ground wire hanging control box is allowed to be opened, if it is detected that the circuit is energized, the ground wire hanging control box cannot be opened.

[0069] After the knife switch is disconnected, the maintenance personnel will check whether the main transformer line is energized by observing the display unit of the intelligent tester. If the intelligent tester detects that the main transformer line is energized, it is confirmed that the main transformer line has residual pressure, and the line is discharged to eliminate the residual charge on the main transformer line, prevent the occurrence of dangerous situations such as accidental electric shock or short circuit during subsequent operations, and reduce operational risks.

[0070] In addition, since the intelligent electric tester is electrically interlocked with the ground wire hook control box, at this time, if the line is detected to be energized, the ground wire hook control box cannot be opened. Only when the intelligent electric tester detects that the line is not energized, the ground wire hook control box is allowed to be opened. Thus, the electric test lock is realized to prevent live grounding operation.

[0071] Step S300, ground wire end hooking step: the intelligent ground wire head is hooked to the ground wire pile, the intelligent ground wire head sends its hooking position and hooking status to the anti-error host, and the anti-error host sends the hooking authority of the ground wire line end and the main transformer line to the ground wire hooking control box.

[0072] After the smart electrical tester detects that there is no power in the line, the maintenance personnel will first hang the smart ground wire head and the ground wire pile to ensure that the specific ground wire head matches the specific smart ground wire pile to prevent misoperation caused by incorrect ground wire hanging and reduce the risk of electric shock.

[0073] After the intelligent ground wire head is connected to the ground wire pile, the intelligent ground wire head sends its connection position and connection status to the anti-error host. After the anti-error host confirms that the intelligent ground wire head and the ground wire pile are connected accurately and successfully, the ground wire connection control box is issued with the connection authority of the ground wire line end and the main transformer line, so that the ground wire connection control box is authorized to allow maintenance personnel to connect the ground wire line end through the ground wire connection control box.

[0074] Step S400, line end hooking step: log in to the ground wire hooking control box to obtain the hooking authority of the ground wire line end and the main transformer line, operate the ground wire lifting mechanism to raise the ground wire line end close to and clamp the main transformer line, and the ground wire line end sends its hooking status to the anti-error host.

[0075] The maintenance personnel log in to the ground wire connection control box using their account and password, and successfully open the door lock of the ground wire connection control box to obtain the connection authority between the ground wire line end and the main transformer line.

[0076] After opening the ground wire hooking control box, the maintenance personnel operate the ground wire lifting mechanism through the ground wire hooking control box to raise the ground wire line end close to and clamp the main transformer line. The ground wire line end sends its hooking status to the anti-error host.

[0077] The anti-mistake host determines that the ground wire connection is completed, the computer key has passed, and prompts to carry out subsequent maintenance work.

[0078] Before the grounding wire is hooked up, the embodiment of the present application uses an intelligent electric tester to test the line of the main transformer, so as to test and lock the grounding wire hooking control box, and manage the login authority of the grounding wire hooking control box by obtaining the hooking authority of the anti-misoperation host, so as to prevent live grounding and misoperation. In addition, when the grounding wire is hooked up, the grounding wire line end is raised to the hooking position by the grounding wire lifting mechanism, which improves the operation efficiency and reduces the operation risk.

[0079] In some embodiments, in the ground wire end hanging step, the method also includes: the anti-error host sends a line end hanging prompt to the ground wire hanging control box; in the line end hanging step, it also includes: the ground wire hanging control box sends a line end hanging application to the anti-error host; after the line end hanging application is approved, the ground wire lifting mechanism performs the line end hanging operation.

[0080] In order to further improve the safety and rigor of the operation, the intelligent ground wire head sends its hanging position and hanging status to the anti-error host. After the anti-error host determines that the intelligent ground wire head and the ground wire pile are hung successfully, it sends a line end hanging prompt to the ground wire hanging control box to remind the maintenance personnel that they can hang the line end of the ground wire.

[0081] Based on the hooking prompt, the maintenance personnel send a line-end hooking application to the anti-error host through the ground wire hooking control box. After the line-end hooking application is approved, the ground wire lifting mechanism is controlled by the ground wire hooking control box to perform the line-end hooking operation.

[0082] In the embodiment of the present application, before the ground wire is hung, a line end hanging application is sent to the anti-mistake host again. After the hanging application is approved, the ground wire lifting mechanism is operated to hang it, which further improves the operation safety.

[0083] In some embodiments, based on Figure 3 It can be seen that the main transformer line includes three-phase lines A, B, and C; in the line-end hanging step, the grounding wire lifting mechanism is operated to raise the grounding wire line end close to and clamp the main transformer line, including: sequentially operating the grounding wire lifting mechanism to raise the grounding wire line ends corresponding to the three-phase lines A, B, and C close to and clamp the corresponding main transformer line.

[0084] The embodiment of the present application controls the connection process of the three-phase lines A, B, and C in sequence, so that the connection process of each phase is properly handled, thereby avoiding safety hazards caused by missing a phase and reducing operational risks.
