[0002] In modern power systems, disconnect switches, as one of the important electrical devices, play a crucial role in isolating power sources, performing switching operations, and connecting and disconnecting low-current circuits. With the continuous advancement of integrated dispatching and remote control, the control of disconnect switches is gradually moving towards remote control operation, aiming to improve work efficiency by remotely controlling the target disconnect switch.
[0003] Current methods for controlling disconnect switches typically involve using a drive motor to close or open the target disconnect switch with a preset torque, achieving remote control. However, over time, the operating parameters of various components within the disconnect switch change due to factors such as equipment aging and wear of transmission parts. This often leads to inadequate control when using a preset torque (e.g., insufficient torque causing the disconnect switch to fail to close, or excessive torque causing the motor to over-rotate).

[0036] Figure 1 This is a flowchart illustrating a disconnector switch control method provided in an embodiment of this application. This embodiment is applicable to situations involving remote control of disconnectors. The method can be executed by a disconnector switch control device, which can be implemented in hardware and / or software and integrated into the electronic device executing the method. Preferably, the electronic device in this embodiment can be a server, or a computer device, etc.
[0037] refer to Figure 1 The disconnector switch control method in this embodiment includes, but is not limited to, the following steps:
[0038] S110. Obtain parameter information generated when multiple drive components of the target disconnect switch are working.
[0039] The target disconnector indicates any disconnector in a power system that needs to be controlled among multiple disconnectors. The control method for the target disconnector generally involves moving the contacts through a control mechanism (such as an operating lever or actuation mechanism) to open or close the contacts, thereby controlling the conduction and disconnection of the control current path.
[0040] In the process of controlling the target disconnect switch, multiple transmission components work together. During this collaboration, due to equipment aging and wear of transmission parts, the parameters generated between these components change, and the parameter changes vary for different disconnect switches. Therefore, in existing solutions that uniformly control each disconnect switch based on a preset torque, some disconnect switches may not be controlled properly, such as failing to close or the motor over-rotating. In view of this, the disconnect switch control scheme provided in this embodiment analyzes the parameters of each transmission component in each disconnect switch using a characteristic calculation model. This model outputs the torque characteristics corresponding to each disconnect switch, enabling precise control of the respective disconnect switch based on these torque characteristics.
[0041] Specifically, in this embodiment, the parameter information includes at least contact parameters, friction parameters, and deformation parameters. Contact parameters indicate the parameters generated when two transmission components come into contact with each other; these parameters are related to the contact area and contact pressure between the two transmission components. Friction parameters indicate the parameters generated at the connection point between two transmission components due to relative motion; these parameters are related to the magnitude of the frictional force between the two transmission components and the speed of movement. Deformation parameters indicate the deformation of the transmission components under pressure; these parameters are related to the material of the transmission components, the magnitude of the pressure, and the magnitude of the control current. The parameter information generated by each transmission component is specifically related to the function corresponding to each transmission component.
[0042] In a preferred embodiment, the target disconnecting switch comprises multiple transmission components including contacts, contact fingers, conductive arms, operating levers, actuating linkages, driven crank arms, inter-pole linkages, and phase-to-phase linkages. Through the coordinated operation of these transmission components, the disconnecting switch performs opening and closing operations, as well as circuit isolation functions. Specifically, the contacts and contact fingers are used to conduct current; the conductive arms conduct current; and the operating levers, actuating linkages, driven crank arms, inter-pole linkages, and phase-to-phase linkages transmit operating force to achieve the mechanical action of the disconnecting switch.
[0043] Specifically, the parameter information generated when the above-mentioned multiple transmission mechanisms are working is as follows: the contact parameters include the first contact parameter and the second contact parameter, and the friction parameters include the first friction parameter and the second friction parameter.
[0044] The first contact parameter is generated when the contactor and contact finger come into contact. The contactor and contact finger are the key parts for realizing the circuit opening and closing. Factors such as the contact area and contact pressure between the two affect the current conduction effect and the contact resistance. The second contact parameter is generated when the conductive arm comes into contact with the contactor and contact finger respectively. The conductive arm is connected to the contactor and contact finger respectively, and its connection points also generate certain contact parameters. For example, the tightness of the connection between the conductive arm and the contact affects the contact resistance and contact stability.
[0045] The first friction parameter is generated when the operating lever and the actuating linkage move relative to each other. The friction between them affects the transmission of operating force and the smoothness of the disconnecting switch's operation. Factors such as the coefficient of friction and the speed of movement determine the magnitude of the friction parameter. The second friction parameter is generated when the driven crank arm moves relative to the inter-pole linkage and the inter-phase linkage, respectively. Their connection points and movement methods affect the magnitude and direction of the friction force.
[0046] Deformation parameters are generated when the contact finger deforms under the pressure of the contact head. The contact finger will deform under the pressure of the contact head and the thermal effect generated when the current passes through. The material properties of the contact finger, the contact pressure and the magnitude of the current will affect the degree and deformation characteristics of the contact finger.
[0047] The solution provided in this embodiment first acquires various parameter information of the target disconnect switch based on microsensors before controlling the target disconnect switch. This parameter information reflects the component operation status of the target disconnect switch in the current state, providing a data foundation for the accuracy of subsequent remote control of the target disconnect switch.
[0048] S120. Input the contact parameters, friction parameters, and deformation parameters into the characteristic calculation model to obtain the torque characteristics of the target disconnector.
[0049] The characteristic calculation model is obtained by training a pre-defined deep learning algorithm on collected sample data. By inputting contact parameters, friction parameters, and deformation parameters into the characteristic calculation model, the torque characteristics of the target disconnector can be obtained relatively accurately. The current torque characteristics can be represented by a curve showing the relationship between time and output torque, or by a function showing the change of time and output torque. Optionally, the torque characteristics include at least the relationship between torque and time in the target disconnector, the maximum torque value, the minimum torque value, and the control method.
[0050] Specifically, when outputting the torque characteristics of the target disconnector through the characteristic calculation model, contact parameters reflect the contact situation between the contacts and fingers of the target disconnector, including contact area and contact pressure. These parameters directly affect current conduction and the magnitude of friction. Friction parameters determine the frictional resistance between different components of the target disconnector during operation, playing a crucial role in the generation and change of torque. Deformation parameters reflect the deformation of the fingers under stress, which may alter the contact state and friction, thus affecting torque characteristics. Furthermore, by comprehensively analyzing these parameters through the characteristic calculation model, the torque changes of the target disconnector at different time points can be simulated. For example, when the target disconnector begins operation, the torque may be large due to the high friction and finger deformation; as operation progresses, the contact state gradually stabilizes, friction may decrease, and the torque will change accordingly. Analyzing the torque characteristics of the target disconnector helps to evaluate and optimize its operational performance, ensuring its reliability and safety in actual operation.
[0051] In a preferred embodiment, the characteristic calculation model is obtained as follows: A sample dataset is acquired, comprising multiple data pairs, each pair including corresponding sample contact parameters, sample friction parameters, sample deformation parameters, and sample torque characteristic data; feature extraction is performed on the sample contact parameters, sample friction parameters, sample deformation parameters, and sample torque characteristic data in each data pair to obtain corresponding sample parameter features; a preset deep learning model is trained based on multiple sample parameter features, and the model parameters of the preset deep learning model are iteratively optimized; when the predicted torque characteristic of the disconnector output by the preset deep learning model meets preset conditions, the characteristic calculation model is obtained.
[0052] The solution provided in this embodiment, when training the characteristic calculation model, uses one-to-one corresponding sample contact parameters, sample friction parameters, sample deformation parameters, and sample torque characteristic data contained in the sample dataset. These data can be obtained through extensive experimental testing of actual disconnecting switches and field operation data. Furthermore, feature extraction is performed on the parameters contained in each data pair to transform the raw data into a form more suitable for model training. Specifically, for contact parameters, possible extracted features include statistical characteristics of the contact area (such as mean and variance), and the changing trend of contact pressure; for friction parameters, features may include the dispersion of the friction coefficient and energy loss characteristics during the friction process; for deformation parameters, features such as the maximum amplitude of finger deformation and the time characteristics of deformation recovery can be extracted; and for torque characteristic data, features such as the peak torque and the slope characteristics of torque change over time can be extracted. These feature extraction operations transform the original sample parameters into sample parameter features. Multiple sample parameter features are used as input, and the corresponding sample torque characteristic data is used as output to train a pre-defined deep learning model. During training, the model attempts to predict torque characteristics based on the input sample parameter features, and then calculates a loss function by comparing it with the actual sample torque characteristic data. Based on the value of the loss function, an optimization algorithm is used to iteratively optimize the model parameters until the predicted torque characteristics of the disconnector output by the pre-defined deep learning model meet the preset conditions, thus obtaining the characteristic calculation model.
[0053] Among them, the above-mentioned preset conditions can be: the number of iterations reaches a preset upper limit value, or the error between the predicted torque characteristics and the actual torque characteristics of the output disconnecting switch is less than a preset value, then the above-mentioned preset conditions are determined to be satisfied.
[0054] The aforementioned preset deep learning model can be implemented using neural network models, support vector machine models, or random forest models, and the specific selection of the preset deep learning model is not limited here.
[0055] Optionally, when the contact parameters include a first contact parameter and a second contact parameter, and the friction parameters include a first friction parameter and a second friction parameter, the first contact parameter and the second contact parameter can be calculated first by weighting, and the first friction parameter and the second friction parameter can be calculated first by weighting, thereby obtaining the corresponding contact parameters and friction parameters. Then, the relevant operations of feature extraction are performed on the sample contact parameters, sample friction parameters, sample deformation parameters and sample torque characteristic data in each data pair.
[0056] S130, The control drive component controls the target disconnect switch according to the torque characteristics.
[0057] When the drive component controls the target disconnect switch based on the torque characteristics, it can clearly determine the torque required to control the opening and closing of the target disconnect switch, thereby enabling the target disconnect switch to be operated in one go and improving the accuracy of operation.
[0058] In this embodiment, the drive component can be implemented by a servo motor. Servo motors have the characteristics of precise control and can adjust the action of the target isolating switch according to the target torque corresponding to the calculated torque characteristics, so as to ensure that it operates at the right time with the appropriate torque.
[0059] The disconnector switch control method provided in this embodiment first acquires parameter information generated by multiple transmission components of the target disconnector switch during operation. This parameter information includes contact parameters, friction parameters, and deformation parameters, which reflect the component operation status of the target disconnector switch in its current state. Then, these parameters are input into a characteristic calculation model, enabling the model to calculate the torque characteristics of the target disconnector switch based on these parameters. The torque characteristics provide a better understanding of the torque changes of the target disconnector switch in its current state. Finally, the control drive component controls the target disconnector switch based on the obtained torque characteristics. The solution provided in this embodiment calculates the parameters of each component corresponding to different disconnectors using a characteristic calculation model. This allows for targeted control of each disconnector switch based on its corresponding torque characteristics, solving the problem of inadequate control in existing remote control methods that rely on preset torque. This improves the control accuracy of remote operation and increases work efficiency.
[0060] Figure 2 This is another flowchart illustrating the isolating switch control method provided in this application embodiment. This application embodiment is an optimization based on the above embodiments. Specifically, the optimization is as follows: This embodiment provides a detailed explanation of the implementation process of "determining target control information from torque characteristics based on the current control time, wherein the target control information includes the target control mode and the target output torque" in the above embodiments.
[0061] See Figure 2 The disconnector switch control method in this embodiment includes, but is not limited to, the following steps:
[0062] S210. Obtain parameter information generated when multiple drive components of the target disconnect switch are working.
[0063] The parameter information includes at least contact parameters, friction parameters, and deformation parameters.
[0064] S220. Input the contact parameters, friction parameters, and deformation parameters into the characteristic calculation model to obtain the torque characteristics of the target disconnector.
[0065] S230. Determine the target control information from the torque characteristics based on the current control time.
[0066] The target control information includes the target control mode and the target output torque.
[0067] In one understandable way, the torque characteristics of the target disconnector in this embodiment can be represented by a curve showing the relationship between time and output torque. The target control mode indicates whether the target disconnector is currently controlled to close or open, and the target output torque represents the torque required to control the target disconnector. Controlling the target disconnector using the target output torque ensures that the target disconnector can be operated correctly in one operation.
[0068] S240, The control drive component controls the target disconnect switch according to the target output torque under the target control mode.
[0069] When the drive component is implemented by a servo motor, the rotation of the servo motor can be controlled to drive the operating mechanism of the disconnect switch to move in accordance with the target output torque.
[0070] Specifically, the process by which the control drive component provided in this embodiment controls the target disconnect switch based on torque characteristics can be implemented in the following way: receiving target control information for the target disconnect switch from a host computer or control system, the target control information including the target control mode and the target output torque; converting the target control information into control instructions that the driver can understand, and controlling the servo motor to rotate according to the instructions, thereby driving the operating mechanism of the disconnect switch to move.
[0071] In another preferred embodiment, the target control method provided in this embodiment includes control closing and control opening. Control closing refers to the operation of closing the contacts of the disconnecting switch to form a circuit. In a power system, when it is necessary to connect an electrical device (such as a transformer, line, etc.) to the circuit for power supply or to connect different circuit parts, the disconnecting switch is closed. Control opening is the opposite of control closing; it refers to the operation of opening the contacts of the disconnecting switch to cut off the circuit. When it is necessary to inspect or maintain electrical equipment or change the operating mode of the power system, the disconnecting switch is opened.
[0072] Specifically, step S240 can be implemented as follows: When the target control mode is control closing, the control drive component operates in a first direction, so that during operation in the first direction, the control mechanism of the target disconnector switch generates a closing operation based on the target output torque. When the target control mode is control opening, the control drive component operates in a second direction, so that during operation in the second direction, the control mechanism of the target disconnector switch generates a opening operation based on the target output torque. The first and second directions are in opposite states.
[0073] Specifically, when representing torque characteristics using a time-to-output torque relationship curve, the control method of the disconnector switch, the motor rotation direction of the drive component, and the function range of the time-to-output torque relationship curve can be predefined. For example, when the control method of the disconnector switch is control closing, the corresponding motor rotation direction can be forward (first direction), which can be reflected in the time-to-output torque relationship curve as the curve corresponding to control closing occupying the first quadrant of the coordinate system (positive value); conversely, when the control method of the disconnector switch is control opening, the corresponding motor rotation direction can be reverse (second direction), which can be reflected in the time-to-output torque relationship curve as the curve corresponding to control closing occupying the fourth quadrant of the coordinate system (negative value); thus, the control mechanism of the disconnector switch can be referenced based on the current relationship to perform closing or opening operations.
[0074] In another preferred embodiment, since the parameters of each transmission component of the disconnecting switch will change over time, in order to further achieve the purpose of precise control of the target disconnecting switch, the solution provided in this embodiment will adjust the model parameters of the characteristic calculation model according to the actual control results after the target disconnecting switch is controlled once according to the solution provided in this embodiment, so as to always maintain the accuracy of the output results of the characteristic calculation model.
[0075] Specifically, the disconnector switch control scheme provided in this embodiment further includes the following steps:
[0076] The control image of the target disconnect switch is obtained based on the vision component. The control image is obtained after the drive component controls the target disconnect switch according to the torque characteristics. Feature extraction is performed on the control image to obtain control features. The control result of the target disconnect switch is determined based on the control features. If the control result does not meet the expected result, the model parameters of the characteristic calculation model are adjusted according to the control result.
[0077] The vision component can be a vision device, such as a high-resolution industrial camera, deployed at the target disconnect switch. After the control and drive component controls the target disconnect switch according to the torque characteristics, the vision component can be controlled to acquire the control image generated after the target disconnect switch is controlled. The current control image should at least include the state information of the target disconnect switch under specific torque control, such as the contact finger engagement status, contact finger engagement depth, and whether the conductive arm is straight.
[0078] Before performing feature extraction on the control image, the control image can be preprocessed. Preprocessing may include grayscale conversion to reduce the amount of data and simplify subsequent processing; it may also include image filtering, noise removal, and other operations to obtain a high-precision control image for subsequent feature extraction.
[0079] Specifically, when extracting features from the control image, a preset extraction algorithm can be used to describe the control features of the disconnector switch. For example, the current control features may include the position of the disconnector switch blade, the state of the contact points, and the contact finger engagement trajectory. Optionally, the preset extraction algorithm in this embodiment can be an edge detection algorithm.
[0080] Before determining the control result for the target disconnector based on control characteristics, a mapping relationship between control characteristics and control results can be established in advance. For example, for controlling closing, if the contact edge spacing is detected to be less than a certain threshold and the contact area is greater than a certain value, the closing operation is considered successful; otherwise, the closing operation is considered unsuccessful. For controlling opening, the positional characteristics of the transmission components (such as the angle and displacement of the transmission rod) and the separation of the contacts can be used to determine whether the opening is complete. Furthermore, the extracted control characteristics are compared with the pre-established mapping relationship to determine the control result for the target disconnector, i.e., whether the operation has successfully achieved the expected state.
[0081] In this embodiment, if the control result does not meet the expected result, the model parameters of the characteristic calculation model can be adjusted according to the control result. The specific adjustment method is as follows: determine the prediction error according to the control result and the expected result; adjust the model parameters based on the preset method and the prediction error to obtain updated parameters; and correct the characteristic calculation model based on the updated parameters.
[0082] When the control result does not meet the expected result, the cause of the prediction error can be determined in advance based on the control result and the expected result. For example, the expected closing result is complete contact with appropriate contact pressure, but the actual control result shows incomplete contact or insufficient contact pressure. Possible causes include inaccurate torque calculation, wear of transmission components, and deformation of the contacts. These causes may be related to the parameters in the characteristic calculation model. The model parameters of the characteristic calculation model can be adjusted based on the analysis results. For example, if inaccurate torque calculation is considered to be the cause of poor control results, the values of torque-related parameters, such as the friction coefficient and load inertia, can be adjusted in the model. If the problem is caused by wear of transmission components, parameters such as transmission efficiency can be corrected according to the wear condition. By continuously adjusting the model parameters and updating the characteristic calculation model, the control of the disconnecting switch based on torque characteristics can more closely approximate the expected result in subsequent operations.
[0083] This embodiment utilizes a vision-based component to further analyze the control results of the target disconnect switch after control, enabling timely detection of potential problems and improving the accuracy and reliability of disconnect switch operation. This method is of great significance for ensuring the safe and stable operation of the power system.
[0084] The disconnector switch control method provided in this embodiment calculates the parameters of each component corresponding to each disconnector switch separately through a characteristic calculation model. This allows for targeted control based on the torque characteristics of the current disconnector switch when controlling each disconnector switch. This solves the problem of inadequate control when remotely controlling a target disconnector switch using a preset torque, and achieves the beneficial effects of improving the control accuracy of remote operation and increasing work efficiency.
[0085] Figure 3 This is a schematic diagram of a disconnector control device provided in an embodiment of this application. This device is suitable for executing the disconnector control method provided in an embodiment of this application. Figure 3 As shown, the device may specifically include: an information acquisition module 310, a model calculation module 320, and a switch control module 330, wherein:

[0088] The switch control module 330 is used to control the drive component to control the target disconnect switch according to the torque characteristics.
[0089] The disconnector switch control device provided in this embodiment first acquires parameter information generated by multiple transmission components of the target disconnector switch during operation. This parameter information includes contact parameters, friction parameters, and deformation parameters, which reflect the component operation status of the target disconnector switch in its current state. Then, these parameters are input into a characteristic calculation model, enabling the model to calculate the torque characteristics of the target disconnector switch based on these parameters. The torque characteristics provide a better understanding of the torque changes of the target disconnector switch in its current state. Finally, the control drive component controls the target disconnector switch based on the obtained torque characteristics. The solution provided in this embodiment calculates the parameters of each component corresponding to each disconnector switch separately using the characteristic calculation model. This allows for targeted control of each disconnector switch based on its corresponding torque characteristics, solving the problem of inadequate control in existing remote control methods that rely on preset torque. This improves the control accuracy of remote operation and enhances work efficiency.
