[0046] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0048] It can be understood that the terms "first", "second", etc. used in this application can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, the first resistor can be called the second resistor, and similarly, the second resistor can be called the first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0049] It can be understood that for "connection" in the following embodiments, if there is an electrical signal or data transfer between the connected circuits, modules, units, etc., it should be understood as "electrical connection", "communication connection", etc.

[0050] It can be understood that "at least one" means one or more, and "a plurality" means two or more. "At least a part of an element" means a part or all of the element.

[0051] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising", "including" or "having", etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0052] In the related art, the management of switchgear nameplates mainly relies on manual operation. The operation and maintenance personnel manually replace the corresponding nameplates according to the changes in the operating status of the switchgear. This method has many inconveniences in the operation process and is prone to omissions. For example, in the case of grid load adjustment, equipment maintenance, etc., the switchgear needs to be frequently operated. Manually replacing the nameplates has the following disadvantages:

[0053] First, the synchronization is poor. When the operation executed based on the dispatching program changes the operating state of the switchgear cabinet, the on-site signboard cannot be automatically switched synchronously, resulting in the maintenance personnel being unable to quickly and accurately judge the state of the switchgear cabinet through the signboard, increasing the risk of misoperation.

[0054] Second, the safety is low. When the operation mode of the switchgear cabinet changes, the signboard that has not been updated synchronously violates the requirements of the safety operation regulations, which may cause personnel misoperation and endanger personal safety and the normal operation of the equipment.

[0055] Third, the work efficiency is low. When the maintenance personnel perform power-on and power-off operations, they need to carry a variety of independent signboards, and special situations such as loss and shortage are likely to occur. Searching for the signboards will delay the power outage project and increase the workload at the grass-roots level.

[0056] To solve the above problems, this embodiment provides a method for controlling the display of the switchgear cabinet signboard, which is applied to a switchgear cabinet device. As Figure 1 shown, the switchgear cabinet device 100 includes: a control module 110, a switching display module 120, and a power supply module 130. Among them, the power supply module 130 is respectively connected to the control module 110 and the switching display module 120, and the control module 110 is connected to the switching display module 120.

[0057] In this embodiment, the power supply module 130 can use an AC220 AC power supply or a high-frequency switching power supply as the power supply, and configure relevant power supply circuits for each circuit element, so as to provide an adapted power supply signal for each circuit element. It should be noted that the high-frequency switching power supply has a small power, and using the high-frequency switching power supply as the power supply can directly draw power inside the switchgear cabinet.

[0058] The control module 110 can use an embedded single-chip microcomputer as the controller. The input signals are the switch-on and switch-off dry contact signals of the switchgear cabinet and the analog signal of the live indicator. Among them, the switch-on and switch-off dry contact signals of the switchgear cabinet are used to indicate the opening and closing states of the circuit breaker and the grounding switch, and the analog signal is used to indicate the display state of the live indicator. The embedded single-chip microcomputer has the characteristics of high reliability and strong anti-interference. The control module 110 is used to determine the display content of the switchgear cabinet signboard according to the data combination of the switch-on and switch-off dry contact signals of the switchgear cabinet and the analog signal of the live indicator. Among them, the display content of the switchgear cabinet signboard can be a fixed truth table. It should be noted that the specific format of the fixed truth table can be configured correspondingly according to the needs of the actual application scenario, and no limit description is made here.

[0059] The switching display module 120 is a signboard display that can switch and display different contents. In a specific embodiment, the switching display module 120 can be a mechanical rotating signboard 121 or an electronic display signboard. The appropriate switching display module 120 can be configured according to the configuration requirements of the actual application scenario.

[0060] In one embodiment, as Figure 2 shown, a control method for the display of switchgear signs is provided. Taking the control module 110 of the switchgear device 100 in Figure 1 as an example, the method includes the following steps:

[0061] S201, obtain a first status signal, a second status signal, and a third status signal, where the first status signal is used to indicate the opening and closing status of the circuit breaker, the second status signal is used to indicate the opening and closing status of the grounding switch, and the third status signal is used to indicate the display status of the live indicator.

[0062] In this embodiment, the circuit breaker is a core component in the switchgear. A circuit breaker is a mechanical switching device that can connect, carry, and break the current under normal circuit conditions, and can also connect, carry for a certain time, and break the current under the specified abnormal circuits (such as short circuits).

[0063] Under normal operating conditions of the switchgear, the circuit breaker is in the closed state to connect the circuit. When the switchgear performs automatic control or protection control operations, the circuit breaker can perform circuit breaking or connecting operations under the control of the protection circuit or the control module 110. The circuit breaker can not only switch on and off the normal load current, but also withstand the short-circuit current for a certain time (several times or even dozens of times the normal operating current), and can break the short-circuit current to cut off the faulty line and equipment. In practical application scenarios, the circuit breaker is usually installed in the circuit breaker room of the switchgear and works in cooperation with components such as the operating mechanism, current transformer, and disconnector. It should be noted that the specific type of the circuit breaker is not limited in this embodiment, and a suitable circuit breaker can be configured for the switchgear according to the needs of the actual application scenario.

[0064] The grounding switch, also known as the grounding switchgear, is a safety interlock mechanism installed in the high-voltage switchgear to replace the grounding wire. The main structure of the grounding switch includes components such as a grounding switch bracket, a grounding knife assembly, a static contact, a driver, a shaft, a crank arm, a compression spring, a conductive bushing, and a flexible connection. The grounding switchgear is configured beside the disconnectors on both sides of the circuit breaker and can play the role of grounding on both sides during the maintenance of the circuit breaker. In the actual application process, when the operating mechanism drives the grounding switchgear to close, as the torque main shaft overcomes the resistance torque, it drives the crank arm to rotate in the closing direction, and makes the operating rod on the grounding knife pass through the dead point of the compression spring, and the compression spring releases energy to make the grounding switch close quickly. When the operating mechanism drives the grounding switchgear to open, the acting torque makes the main shaft overcome the resistance torque, drives the crank arm to rotate in the opening direction, and makes the operating rod on the grounding knife pass through the dead point of the compression spring, and the compression spring stores energy for the next closing.

[0065] A live indicator, also known as an electric field intensity indicator, is a power equipment used to detect the electric field intensity in power equipment, that is, to determine whether the equipment is live, so as to ensure safe operation. The working principle of the live indicator is mainly based on electrostatic induction and electric field coupling. When a live body approaches the indicator, electrostatic induction will occur between the live body and the indicator, causing the charge distribution inside the indicator to change. This change will, through the action of electric field coupling, cause corresponding changes in the indicator lights or signal output interfaces on the indicator, thereby showing the live state of the circuit breaker and the earthing switch.

[0066] In this embodiment, the control module 110 is respectively connected to the relevant circuits of the circuit breaker, the earthing switch and the live indicator, and is used to receive the status signals fed back by the circuit breaker, the earthing switch and the live indicator after completing the corresponding operations. It should be noted that the circuit breaker, the earthing switch and the live indicator will perform relevant operations according to the real-time control commands of the switch cabinet in the actual application scenario.

[0067] S202, determine the target indication content according to the first status signal, the second status signal and the third status signal.

[0068] In this embodiment, there are multiple target indication contents. For example, the target indication contents include "operating", "different power sources, no closing allowed" and "no closing allowed, someone is working on the line", etc. It should be noted that the specific text descriptions of the target indication contents can be custom-configured according to the needs of the actual application scenario.

[0069] In this embodiment, the target indication content can be fixed as a truth table or a display signal. The specific form of the target indication content can be defined according to the needs of the actual application scenario.

[0070] S203, control the switching display module 120 to display the target indication content.

[0071] In this embodiment, after determining the target indication content according to the first status signal, the second status signal and the third status signal, the control module 110 will immediately control the switching display module 120 to refresh the display content according to the target indication content, so as to timely indicate the operation status of the switch cabinet to the operation and maintenance personnel.

[0072] In summary, the switch cabinet sign display control method provided in this embodiment can realize the efficient and accurate switching of the switch cabinet signs, greatly improve the work efficiency, and effectively avoid the possible forgetting and errors in the manual operation process. And the automatic switching mechanism can realize fast and accurate sign switching, completely free from the interference of human factors, and ensure the timeliness and accuracy of the switch cabinet status display.

[0073] In one of the embodiments, such as Figure 3As shown, determining the target indication content according to the first state signal, the second state signal and the third state signal includes:

[0074] S301: If the circuit breaker is in a closed state and the grounding switch is in an open state, determine that the target indication content is the first content.

[0075] S302: If the circuit breaker is in an open state, the grounding switch is in an open state, and the power indicator is in a lighted state, determine that the target indication content is the second content.

[0076] S303: If the circuit breaker is in an open state, the grounding switch is in a closed state, and the power indicator is in an off state, determine that the target indication content is a third content.

[0077] In this embodiment, the first content may be "in operation", the second content may be "different power supply, switch-on prohibited", and the third content may be "switch-on prohibited, someone is working on the line". It should be noted that the text of the first content, the second content, and the third content may be replaced by other languages or texts with the same meaning.

[0078] When the equipment is in normal operation, the circuit breaker is in the closed state and the grounding switch is in the open state. At this time, the signboard will clearly display "in operation", intuitively conveying the operating status of the equipment to the operation and maintenance personnel.

[0079] If the circuit breaker of the switch cabinet is in the disconnected state, the grounding switch is also in the disconnected state and the power light is on, the signboard will immediately switch to display "Different power sources, do not close the switch", which clearly reminds personnel to pay attention to safety and avoid the risk of electric shock.

[0080] When the circuit breaker of the switch cabinet is disconnected, the grounding switch is closed and the live light is off, the signboard will accurately display "Do not close the circuit breaker, someone is working on the line", strictly warning against closing the circuit breaker and ensuring that maintenance personnel can carry out equipment maintenance work in a safe environment.

[0081] In one embodiment, if Figure 4 As shown, the switching display module 120 includes a mechanical rotating sign 121 and a driving unit 122 , and the driving unit 122 is connected to the control module 110 .

[0082] In this embodiment, the mechanical rotating sign 121 includes a rotating mechanism and a sign mechanism, wherein the sign mechanism is mechanically connected to the rotating mechanism through a bracket structure, and the rotating mechanism drives the sign mechanism to rotate when it rotates. The sign mechanism is used to display the first display content, the second display content, and the third display content. The interval angle values between the sign mechanism corresponding to the first display content, the sign mechanism corresponding to the second display content, and the sign mechanism corresponding to the third display content can be the same or different.

[0083] The control module 110 sends a control signal to the drive unit 122 to cause the drive unit 122 to drive the rotating mechanism of the mechanical rotating sign 121 to rotate at the target power.

[0084] As Figure 5 shown, the control switching display module 120 displays the target indication content, including:

[0085] S501, obtain the current position of the mechanical rotating sign 121.

[0086] S502, determine the target angle according to the target indication content and the current position.

[0087] S503, control the drive unit 122 to drive the mechanical rotating sign 121 to rotate the target angle in a preset direction until the mechanical rotating sign 121 is in the target position to display the target indication content.

[0088] In this embodiment, a non-contact photoelectric detection method can be used to obtain the current position of the mechanical rotating sign 121. It should be noted that a photoelectric sensor is also provided on the mechanical rotating sign 121 in this embodiment, and the photoelectric sensor is used to collect the real-time positions of the rotating mechanism and the sign mechanism.

[0089] In this embodiment, after determining the current position of the mechanical rotating sign 121, the angle difference between the target position and the current position can be determined according to the sign mechanism corresponding to the target indication content, that is, the target angle. Then, by controlling the drive unit 122 to drive the mechanical rotating sign 121 to rotate the target angle in a preset direction, the corresponding sign mechanism is placed in the display area, and the display area displays the target indication content.

[0090] In this embodiment, the preset direction can be defined as from left to right or from right to left according to the needs of the actual application scenario. In a feasible embodiment, the control module 110 can also obtain the angle differences between the current position and the target position in different directions and select the smaller angle difference as the target angle to ensure that the rotating mechanism can rotate a shorter distance.

[0091] In a specific embodiment, the target angle can also be replaced with a target power value or other parameter values related to the rotation amount of the mechanical rotating sign 121.

[0092] In one of the embodiments, the mechanical rotating sign 121 further includes a reduction gear set, and the drive unit 122 drives the mechanical rotating sign 121 through the reduction gear set;

[0093] Controlling the drive unit 122 to drive the mechanical rotating sign 121 to rotate the target angle in a preset direction includes:

[0094] Control the mechanical rotating signboard 121 to rotate a target angle at a preset speed.

[0095] In this embodiment, the preset speed can be determined according to the rotation stability requirements of the mechanical rotating signboard 121. The rotating structure drives all the display boards to rotate. The motor passes through a reduction gear set to reduce the speed and amplify the torque, enabling the rotating signboard to rotate more stably and precisely.

[0096] In one embodiment, after the control drive unit 122 drives the mechanical rotating signboard 121 to rotate a target angle in a preset direction, the method further includes:

[0097] Obtain the rotation feedback signal of the mechanical rotating signboard 121;

[0098] Control the mechanical rotating signboard 121 to perform calibration rotation according to the rotation feedback signal, so that the mechanical rotating signboard 121 stops at the target position.

[0099] In this embodiment, the position detection of the signboard adopts a non-contact photoelectric detection scheme. As the feedback signal for the signboard to rotate in place, combined with a software algorithm, it realizes adaptive calibration of the position, enabling the mechanical rotating signboard 121 to stop more accurately.

[0100] In one embodiment, the switching display module 120 includes a liquid crystal display screen or an organic light-emitting diode display screen. Controlling the switching display module 120 to display the target indication content includes:

[0101] Obtain the display signal corresponding to the target indication content;

[0102] Control the liquid crystal display screen or the organic light-emitting diode display screen to refresh according to the display signal to display the target indication content.

[0103] In this embodiment, an electronic display screen such as a liquid crystal display screen (LCD) or an organic light-emitting diode display screen (OLED) can be used to replace the signboard mechanism, such as a rotating shaft curtain display signboard. The electronic display screen can be programmed to switch different identification contents and has advantages such as clear display and rich colors.

[0104] In summary, this embodiment provides a switch cabinet sign display control method, which can ensure that the operator can obtain the real-time status of the switch cabinet in time through remote operation, and effectively prevent misoperation. For example, during maintenance, it accurately displays "Maintenance, do not close the switch!" to prevent others from closing the switch and endangering the safety of maintenance personnel. The real-time and synchronous sign display reduces the risk of safety accidents caused by misjudgment of the status. Accurate status identification helps to detect abnormalities in time and take measures. When a power grid fails, it can quickly indicate relevant warning information to help operation and maintenance personnel quickly locate and deal with the problem, reduce the time and scope of power outages, and enhance the stability and reliability of the power grid. Meet the safety regulations and standards of the power industry, ensure the standardization of power facility operation and management, and reduce the legal risks caused by violations of regulations.
