Description

Technical Field

[0001] This application relates to the field of electrical control technologies, and particularly to a monitoring device, method, storage medium, and computer device for an anti-jump circuit. Background Art

[0002] In a power system, a circuit breaker is an important device for connecting the power grid, controlling the on / off of power grid equipment and lines, sending out or disconnecting load current, and cutting off faults. When the closing time is too long and a permanent fault occurs on the line, the circuit breaker will experience a "jumping" phenomenon of repeated opening and closing. "Jumping" not only reduces the arc extinguishing performance of the circuit breaker's arc extinguishing chamber, causing the equipment to be damaged or even malfunctioned by multiple impacts of the fault current, but also affects the stable operation of the power grid. Therefore, an anti-jump circuit must be installed in the circuit breaker control circuit.

[0003] Currently, during the engineering commissioning stage, the acceptance personnel have cumbersome steps when inspecting the function of the anti-jump circuit, requiring two people to cooperate in operation, with low efficiency; during the operation process after the project is put into operation, when the anti-jump circuit fails, the maintenance personnel cannot find the fault location in the first place, thus unable to eliminate the fault in time, and further affecting the normal function of the circuit breaker control circuit.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0041] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0042] In the present invention, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] The present invention will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0044] It should be noted that, as Figure 1As shown in the figure, the components of the circuit breaker control loop are described: the trip position monitoring loop, the closing control loop, and the anti - bounce loop. Among them, the trip position monitoring loop: one end of the trip position relay TWJ is connected to the positive power supply, and the other end is sequentially connected in series from left to right with the first normally - closed auxiliary contact KCF (ports 1, 2) of the anti - bounce relay, the first normally - closed auxiliary contact QF1 of the circuit breaker, the second normally - closed auxiliary contact QF2 of the circuit breaker, the closing coil HC, and the second normally - closed auxiliary contact KCF (ports 3, 4) of the anti - bounce relay, and then connected to the negative power supply. The closing control loop: the manual closing contact SHJ and the reclosing contact ZHJ are connected in parallel, one end is connected to the positive power supply, and the other end is connected between the first normally - closed auxiliary contact QF1 of the circuit breaker and the second normally - closed auxiliary contact QF2 of the circuit breaker. The anti - bounce loop: the first normally - open auxiliary contact KCF (ports 5, 6) of the anti - bounce relay is connected in parallel with the normally - open auxiliary contact QF3 of the circuit breaker. One end is connected between the first normally - closed auxiliary contact QF1 of the circuit breaker and the second normally - closed auxiliary contact QF2 of the circuit breaker, and the other end is connected to one end of the anti - bounce relay KCF. The other end of KCF is connected to the negative power supply. Among them, the second normally - open auxiliary contact KCF (ports 7, 8) of the anti - bounce relay is connected in parallel with the anti - bounce relay KCF.

[0045] The working principle of the anti - bounce function of the anti - bounce loop: After the circuit breaker control loop is powered on, if the light of the trip position relay TWJ is on, it indicates that the trip position monitoring loop is conducting and the loop is intact, and the circuit breaker can be closed. After the manual closing contact SHJ or the reclosing contact ZHJ is closed, a closing command is sent, the closing control loop is conducting, the circuit breaker closes, the first normally - closed auxiliary contact QF1 and the second normally - closed auxiliary contact QF2 of the circuit breaker open, and the normally - open auxiliary contact QF3 of the circuit breaker closes, and the anti - bounce loop is conducting. After the anti - bounce loop is conducting, the second normally - closed auxiliary contact KCF (ports 3, 4) of the anti - bounce relay opens, cutting off the closing control loop. In this way, even if the closing command is continuously sent, the circuit breaker will not close. Therefore, the role of the anti - bounce loop is to prevent the jumping phenomenon of the circuit breaker from tripping and then closing.

[0046] The following will be combined with Figure 1 Describe a monitoring device for the anti - bounce loop according to some embodiments of the present invention.

[0047] Embodiments of the present invention provide a monitoring device for the anti - bounce loop, as Figure 1As shown in the figure, the monitoring device includes: a test / operation button 1, an operation time measurement button 2, and an operation voltage measurement button 3; switch the test / operation button 1 to the test state; the monitoring device is built into the mechanism box and is connected to both ends of the first normally closed auxiliary contact of the anti-jump relay in the anti-jump circuit, and is also connected to both ends of the first normally closed auxiliary contact of the circuit breaker in the anti-jump circuit. The operation time measurement button 2 is used to start the monitoring device to measure the first operation time of the first normally closed auxiliary contact of the anti-jump relay and the second operation time of the first normally closed auxiliary contact of the circuit breaker. Among them, the mechanism box is located at the local end; the monitoring device is connected to both ends of the anti-jump relay in the anti-jump circuit, and the operation voltage measurement button 3 is used to start the monitoring device to measure the operation voltage of the anti-jump relay; after the first operation time is not zero, less than the second operation time and the first operation time is not zero, and the operation voltage is within the preset range, switch the test / operation button 1 to the operation state to monitor whether the anti-jump relay fails.

[0048] In a specific application scenario, such as Figure 1 As shown in the figure, the device further includes: a display screen 5; the display screen 5 is used to display the first operation time, the second operation time, and the operation voltage; when the first operation time is not zero, less than the second operation time, and the operation voltage is within the preset range, the display screen 5 is further used to display a prompt message indicating that the test has passed; when the first operation time is zero, greater than or equal to the second operation time, or the operation voltage is not within the preset range, the display screen 5 is further used to display a prompt message indicating that the test has failed.

[0049] Among them, the monitoring device is installed in the mechanism box as a part of the mechanism box, and its appearance includes a test / operation knob 1, an operation time measurement button 2, and an operation voltage measurement button 3. The monitoring device has been connected to both ends of the first normally closed auxiliary contact KCF (ports are 1, 2) of the anti-jump relay in the anti-jump circuit, the first normally closed auxiliary contact QF1 of the circuit breaker, and both ends of the anti-jump relay KCF at the factory. The test / operation knob 1 is used to switch the working state of the device. When debugging or performing regular inspections, switch the test / operation button 1 to the test state to detect the anti-jump circuit and the anti-jump relay. Specifically:

[0050] (1) Press the operation time measurement button. Through the timing function of the integrated chip or digital circuit installed inside, measure the first operation time TK of the first normally closed auxiliary contact KCF (ports are 1, 2) of the anti-jump relay and the second operation time TQ of the first normally closed auxiliary contact QF1 of the circuit breaker. The test results of TK and TQ will be displayed on the display screen 5. If TK < TQ, the anti-jump circuit function is normal; if TK ≥ TQ, the anti-jump circuit function fails due to node competition; if TK = 0, the first normally closed auxiliary contact of the anti-jump relay does not operate, and the anti-jump function may fail due to the generation of a parasitic circuit.

[0051] (2) Press the operating voltage measurement button. Through the voltage measurement function of the internally installed integrated chip or digital circuit, measure the operating voltage of the anti-pumping relay KCF. The test result of the operating voltage will be displayed on the display screen 5. If the operating voltage is within the range of 55%-70% of the rated DC power supply, the anti-pumping relay meets the anti-measurement requirements.

[0052] It should be noted that if TK < TQ, the anti-pumping loop function is normal. However, the normal anti-pumping loop function does not mean that the anti-pumping relay meets the anti-measurement requirements. Therefore, it is necessary to judge whether the anti-pumping loop function is normal and whether the anti-pumping relay meets the anti-measurement requirements. If the anti-pumping loop function is normal and the anti-pumping relay meets the anti-measurement requirements, then a prompt message indicating that the test has passed will be directly displayed on the display screen 5, and the staff can directly view it without having to calculate by themselves, which improves the inspection efficiency.

[0053] Since the monitoring device is built into the mechanism box, there is no need to carry an additional detection device, nor is it necessary to connect wires during the test. Compared with the existing technology where the steps are cumbersome during the engineering commissioning stage when the staff checks the anti-pumping loop function and two people are required to cooperate in the operation, this solution can directly carry out the detection, greatly facilitating the operation and maintenance work and improving the inspection efficiency.

[0054] After passing the inspection, switch the test / operation button 1 to the operation state, and use the monitoring device to monitor whether the anti-pumping relay fails during normal operation.

[0055] In a specific application scenario, such as Figure 1 shown, the device further includes: an anti-pumping monitoring lamp 4; use the anti-pumping monitoring lamp 4 to monitor whether the anti-pumping relay has a fault. If the anti-pumping monitoring lamp 4 displays according to the rule corresponding to the existence of a fault in the anti-pumping relay, then the anti-pumping relay has a fault; if the anti-pumping monitoring lamp 4 displays according to the rule corresponding to the non-existence of a fault in the anti-pumping relay, then the anti-pumping relay has no fault.

[0056] Exemplarily, if the anti-pumping relay has no fault, then activate the switch for the anti-pumping monitoring lamp 4 to be green, and the anti-pumping monitoring lamp 4 will display green; if the anti-pumping relay has a fault, then activate the switch for the anti-pumping monitoring lamp 4 to be red, and the anti-pumping monitoring lamp 4 will display red.

[0057] Such as Figure 1 shown, in the anti-pumping loop, the monitoring device is connected to both ends of the anti-pumping relay KCF. When the anti-pumping relay KCF fails, the anti-pumping monitoring lamp 4 will perform corresponding actions (such as turning red). Because the monitoring device is connected to the anti-pumping relay KCF, the local end can directly determine that it is the anti-pumping relay KCF that has failed rather than other anti-pumping relays, that is, the fault location is located in a timely manner.

[0058] Correspondingly, such asFigure 1 As shown, the second normally open auxiliary contact of the anti-jump relay is connected to the microcomputer measurement and control cabinet 6; when the anti-jump relay fails, the fault signal is transmitted to the background display platform 7 through the microcomputer measurement and control cabinet 6, and a message alarm is displayed on the background display platform 7, where the background display platform 7 is located remotely.

[0059] Among them, as Figure 1 shown, the second normally open auxiliary contact KCF (ports 7 and 8) of the anti-jump relay is connected in parallel with the anti-jump relay KCF, in order to connect the second normally open auxiliary contact KCF (ports 7 and 8) of the anti-jump relay to the microcomputer measurement and control cabinet 6, so that when the anti-jump relay fails, the fault signal can be timely transmitted to the background display platform 7 through the microcomputer measurement and control cabinet 6. It should be noted that when the anti-jump relay fails, any normally closed auxiliary contact and any normally open auxiliary contact of the anti-jump relay will fail. Specifically, after receiving the fault signal, the microcomputer measurement and control cabinet 6 transmits the fault signal to the background display platform 7 through the Ethernet, and then a message alarm pops up on the background display platform 7.

[0060] Among them, the background display platform 7 is located remotely, which can facilitate the staff at the remote end to perform corresponding maintenance operations according to the message alarm. The anti-jump monitoring lamp 4 is on the monitoring device, and the monitoring device is located in the mechanism box, and the mechanism box is at the local end. Therefore, through the combination of the anti-jump monitoring lamp 4 and the background display platform 7, the fault can be prompted and the fault location can be found both at the local end and at the remote end, thereby improving the fault troubleshooting efficiency of the circuit breaker control loop.

[0061] A monitoring method for an anti-jump circuit provided by the present invention, the monitoring method of the anti-jump circuit is applied to a monitoring device for an anti-jump circuit such as Figure 1 shown, see Figure 2 , and may include the following steps:

[0062] 101. Measure the first action time of the first normally closed auxiliary contact of the anti-jump relay and the second action time of the first normally closed auxiliary contact of the circuit breaker, and determine whether the first action time is not zero and less than the second action time. If so, it is determined that the anti-jump circuit has no fault. If not, check the anti-jump circuit until the first action time is not zero and less than the second action time.

[0063] In a specific application scenario, measure the first action time TK of the first normally closed auxiliary contact KCF (ports 1 and 2) of the anti-jump relay and the second action time TQ of the first normally closed auxiliary contact QF1 of the circuit breaker. If TK < TQ, the anti-jump circuit function is normal; if TK ≥ TQ, the anti-jump circuit function fails due to node competition; if TK = 0, the first normally closed auxiliary contact of the anti-jump relay does not act, and the anti-jump function may fail due to the generation of a parasitic loop.

[0064] When TK≥TQ or TK = 0, check the anti - bounce loop. After troubleshooting, perform the detection again until TK<TQ, which means the anti - bounce loop functions properly.

[0065] 102. Measure the operating voltage of the anti - bounce relay and determine whether the operating voltage is within the preset range. If so, it is determined that the anti - bounce relay in the anti - bounce loop is fault - free. If not, replace the anti - bounce relay until the operating voltage is within the preset range.

[0066] In a specific application scenario, measure the operating voltage of the anti - bounce relay KCF. If the operating voltage is within the range of 55% - 70% of the rated DC power supply, the anti - bounce relay meets the anti - measure requirements.

[0067] If the anti - bounce relay does not meet the requirement that the operating voltage is within the range of 55% - 70% of the rated DC power supply, after replacing the anti - bounce relay, measure the operating voltage of the anti - bounce relay again until the operating voltage is within the range of 55% - 70% of the rated DC power supply, which means the anti - bounce relay meets the anti - measure requirements.

[0068] 103. When the anti - bounce loop is fault - free and the anti - bounce relay is fault - free, it is determined that the anti - bounce loop and the anti - bounce relay can be put into use.

[0069] In a specific application scenario, if TK<TQ, the anti - bounce loop functions properly. However, the normal function of the anti - bounce loop does not mean that the anti - bounce relay meets the anti - measure requirements. Therefore, it is necessary to judge whether the anti - bounce loop functions properly and whether the anti - bounce relay meets the anti - measure requirements. Only when the anti - bounce loop is fault - free and the anti - bounce relay is fault - free, it is determined that the anti - bounce loop and the anti - bounce relay can be put into use.

[0070] 104. Monitor the anti - bounce relay. If the anti - bounce relay fails, transmit the fault information to the background display platform and display a message alarm on the background display platform.

[0071] In a specific application scenario, before the project is put into production or during regular inspections, the anti - bounce loop and the anti - bounce relay are tested. When the test passes, it means that the anti - bounce loop and the anti - bounce relay can be put into use, and then the anti - bounce relay in the daily operation state is monitored in real - time.

[0072] Among them, when the anti - bounce relay fails, the fault information can be directly displayed at the local end. For example, the anti - bounce display light can emit red light or the anti - bounce display light can go out, etc. The fault can also be transmitted to the remote background display platform through Ethernet, and a message alarm is displayed remotely so that the staff in the background can directly see the fault information. In this way, through the combination of the local end and the remote end, the fault can be prompted and the fault location can be found at both the local end and the remote end, thereby improving the efficiency of troubleshooting the circuit breaker control loop.

[0073] Based on the above Figure 2 shown method, correspondingly, this embodiment also provides a storage medium, which can be specifically volatile or non - volatile, and has computer - readable instructions stored thereon. When the readable instructions are executed by a processor, the monitoring method of the anti - bounce loop as shown in Figure 2 above is implemented.

[0074] Based on such an understanding, the technical solution of this application can be embodied in the form of a software product. The software product can be stored in a storage medium (which can be a CD - ROM, USB flash drive, mobile hard disk, etc.), and includes several instructions to enable a computer device (which can be a personal computer, server, or network device, etc.) to execute the methods of various implementation scenarios of this application.

[0075] Based on the above as Figure 2 shown method, to achieve the above - mentioned purpose, this embodiment also provides a computer device, which includes a storage medium and a processor; the storage medium is used to store a computer program; the processor is used to execute the computer program to implement the monitoring method of the anti - bounce loop as shown in Figure 2 above.

[0076] Optionally, the computer device may further include a user interface, a network interface, a camera, a radio frequency (RF) circuit, sensors, an audio circuit, a WI - FI module, etc. The user interface may include a display screen (Display), an input unit such as a keyboard (Keyboard), etc. Optionally, the user interface may further include a USB interface, a card reader interface, etc. The network interface may optionally include a standard wired interface, a wireless interface (such as a WI - FI interface), etc.

[0077] Those skilled in the art can understand that the structure of a computer device provided in this embodiment does not constitute a limitation on the entity device, and may include more or fewer components, or combine certain components, or have different component arrangements.

[0078] The storage medium may further include an operating system and a network communication module. The operating system is a program for managing the hardware and software resources of the above computer device, and supports the operation of the information processing program and other software and / or programs. The network communication module is used to implement the communication between the components inside the storage medium, as well as the communication between other hardware and software in the information processing entity device.

[0079] Through the description of the above embodiments, those skilled in the art can clearly understand that the present application can be implemented by means of software plus a necessary general hardware platform, or can be implemented by hardware.

[0080] By applying the technical solution of the present application, compared with the current prior art, the present application discloses a monitoring device, method, storage medium and computer device for an anti-jump loop. By means of the above method, the first action time of the first normally closed auxiliary contact of the anti-jump relay and the second action time of the first normally closed auxiliary contact of the circuit breaker can be measured first, and it is judged whether the first action time is not zero and less than the second action time. If so, it is determined that the anti-jump loop is fault-free. If not, the anti-jump loop is checked until the first action time is not zero and less than the second action time; then, the action voltage of the anti-jump relay is measured, and it is judged whether the action voltage is within the preset range. If so, it is determined that the anti-jump relay in the anti-jump loop is fault-free. If not, the anti-jump relay is replaced until the action voltage is within the preset range; further, when the anti-jump loop is fault-free and the anti-jump relay is fault-free, it is determined that the anti-jump loop and the anti-jump relay can be put into use; finally, the anti-jump relay is monitored. If the anti-jump relay fails, the fault information is sent to the background display platform, and a message alarm is displayed on the background display platform.

[0081] In the solution provided by the present application, during the engineering debugging stage or the regular inspection of the anti-jump loop after the project is put into operation, the anti-jump loop and the anti-jump relay can be conveniently and quickly inspected. Compared with the prior art, when the staff inspect the function of the anti-jump loop during the engineering debugging stage, the steps are cumbersome and two people are required to cooperate in the operation. This solution can directly carry out the detection, greatly facilitating the operation and maintenance work and improving the inspection efficiency. During the daily operation process after the project is put into operation, the anti-jump relay is monitored at any time. When the anti-jump relay fails, the fault location can be found in time both locally and remotely, thereby improving the troubleshooting efficiency of the circuit breaker control loop and enabling the system to quickly return to the normal operation state.

[0082] Those skilled in the art can understand that the attached drawings are only schematic diagrams of a preferred implementation scenario, and the modules or processes in the attached drawings are not necessarily essential for implementing the present application. Those skilled in the art can understand that the modules in the devices in the implementation scenario can be distributed in the devices of the implementation scenario according to the description of the implementation scenario, or can be correspondingly changed and located in one or more devices different from the present implementation scenario. The modules in the above implementation scenario can be combined into one module, or can be further split into multiple sub-modules.
