[0036] Figure 1 A flowchart of the isolating switch control method provided in the embodiment of the present application is provided. The present embodiment is applicable to the case of remotely controlling the isolating switch. The method can be executed by an isolating switch control device, which can be implemented in the form of hardware and / or software and integrated in an electronic device that executes the method. Preferably, the electronic device in the embodiment of the present application can be a server, or a computer device, etc.

[0037] refer to Figure 1 The isolating switch control method of this embodiment includes but is not limited to the following steps:

[0038] S110. Obtain parameter information generated when multiple transmission components of the target disconnector are in operation.

[0039] The target disconnector indicates any disconnector that needs to be controlled among multiple disconnectors in the power system. The control method of the target disconnector is generally to drive the movement of the contact by controlling the control mechanism (such as the operating lever and the operating mechanism, etc.) of the target disconnector to realize the opening or closing operation of the contact, thereby realizing the conduction and disconnection of the control current path.

[0040] In the process of controlling the target disconnector, the cooperation of multiple transmission components is involved, and when multiple transmission components cooperate, the parameters generated between the transmission components will change due to reasons such as equipment aging and wear of transmission parts, and the changes in the corresponding parameters of different disconnectors are different. Therefore, in the existing scheme, each disconnector is uniformly controlled according to the preset torque, and there are situations where some disconnectors are not properly controlled, such as not closed or the motor is over-rotating. In view of this, the disconnector control scheme provided in this embodiment can analyze the parameters of each transmission component in each disconnector through a characteristic calculation model, so that the characteristic calculation model outputs the torque characteristics corresponding to each disconnector, thereby accurately controlling the corresponding disconnector according to the torque characteristics corresponding to each disconnector.

[0041] Specifically, in this embodiment, the parameter information includes at least contact parameters, friction parameters and deformation parameters. Among them, the contact parameters indicate the parameters generated when each two transmission components contact each other, and the contact parameters are related to the contact area and contact pressure between the two transmission components; the friction parameters indicate the parameters generated by the relative movement at the connection between each two transmission components, and the friction parameters are related to the magnitude of the friction force between the two transmission components and the movement speed; the deformation parameters indicate the deformation of the transmission component caused by pressure, and the friction parameters are related to the material, pressure and control current of the transmission component. The specific parameter information generated by each transmission component is related to the corresponding function of each transmission component.

[0042] In a preferred embodiment, the multiple transmission components of the target disconnector include contacts, contact fingers, conductive arms, bracket operating rods, operating connecting rods, driven crank arms, inter-pole connecting rods and inter-phase connecting rods. Through the cooperation of these transmission components, the opening and closing operations of the disconnector and the circuit isolation function are realized. Among them, the contacts and contact fingers are used to conduct current; the conductive arms play the role of conducting current; the bracket operating rods, operating connecting rods, driven crank arms, inter-pole connecting rods and inter-phase connecting rods are used to transmit operating forces to realize the mechanical action of the disconnector.

[0043] Specifically, the parameter information generated when the above-mentioned multiple transmission mechanisms are working is as follows: 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.

[0044] Among them, the first contact parameter is generated when the contact head and the contact finger are in contact. The contact head and the contact finger are the key parts to realize the on-off of the circuit. The contact area, contact pressure and other factors between the two will affect the conduction effect of the current and the size of the contact resistance. The second contact parameter is generated when the conductive arm is in contact with the contact head and the contact finger respectively. The conductive arm is connected to the contact head and the contact finger respectively, and its connection part will also produce certain contact parameters. For example, the connection tightness between the conductive arm and the contact will affect the contact resistance and contact stability.

[0045] The first friction parameter is generated when the operating lever and the operating connecting rod move relative to each other. The friction between them will affect the transmission of the operating force and the smoothness of the disconnector. The friction coefficient, movement speed and other factors will determine the size of the friction parameter. The second friction parameter is generated when the driven crank arm moves relative to the inter-pole connecting rod and the inter-phase connecting rod respectively. Their connection parts and movement modes will affect the size and direction of the friction force.

[0046] The deformation parameters are generated when the contact finger is deformed under the pressure of the contact. The contact finger will deform under the pressure of the contact and the thermal effect generated when the current passes through. Factors such as the material properties of the contact finger, contact pressure and current size will affect the deformation degree and deformation characteristics of the contact finger.

[0047] The solution provided in this embodiment first obtains the parameter information of the target isolating switch based on the microsensor before controlling the target isolating switch, so as to reflect the component operation status of the target isolating switch in the current state through these parameter information, and provide a data basis for the accuracy of subsequent remote control of the target isolating switch.

[0048] S120, inputting 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 the preset deep learning with the collected sample data. By inputting the contact parameters, friction parameters and deformation parameters into the characteristic calculation model, the torque characteristics of the target disconnector can be obtained more accurately. The current torque characteristics can be represented by the relationship between time and output torque, or by the change function of time and output torque. Optionally, the torque characteristics at least include the relationship between the change of torque over time, the maximum torque value, the minimum torque value and the control method in the target disconnector.

[0050] Specifically, when the torque characteristics of the target disconnector are output through the characteristic calculation model, the contact parameters can reflect the contact conditions between the contact and the contact finger of the target disconnector, including the contact area, contact pressure, etc. These parameters will directly affect the conduction of current and the magnitude of friction. The friction parameter determines the friction resistance between different components of the target disconnector during the operation process, and plays an important role in the generation and change of torque. The deformation parameter reflects the deformation of the contact finger under force. This deformation may change the contact state and friction, thereby affecting the torque characteristics. Then, through the characteristic calculation model, a comprehensive analysis of these parameters can be performed to simulate the torque changes of the target disconnector at different time points. For example, when the target disconnector starts to operate, the torque may be large due to the large friction and the deformation of the contact finger; as the operation proceeds, the contact state gradually stabilizes, the friction may decrease, and the torque will change accordingly. By analyzing the torque characteristics of the target disconnector, it is helpful to evaluate and optimize the operating performance of the target disconnector to ensure its reliability and safety in actual operation.

[0051] A preferred embodiment, in this embodiment, the characteristic calculation model is obtained in the following manner: obtaining a sample data set, the sample data set including multiple data pairs, each data pair including one-to-one corresponding sample contact parameters, sample friction parameters, sample deformation parameters and sample torque characteristic data; performing feature extraction 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; training a preset deep learning model based on multiple sample parameter features, and iteratively optimizing the model parameters of the preset deep model, and obtaining the characteristic calculation model when the predicted torque characteristics of the disconnector output by the preset deep learning model meet preset conditions.

[0052] When training the characteristic calculation model, the scheme provided in this embodiment includes the one-to-one corresponding sample contact parameters, sample friction parameters, sample deformation parameters and sample torque characteristic data contained in the sample data set, which can be obtained through a large number of experimental tests on actual disconnectors and field operation data collection; further, the parameters contained in each data pair are feature extracted to convert the original data into a form more suitable for model training. Specifically, for contact parameters, the features that may be extracted include statistical features of the contact area (such as mean, variance), the changing trend of contact pressure, etc.; for friction parameters, the discrete degree of friction coefficient, energy loss characteristics in the friction process, etc. may be involved; for deformation parameters, the maximum amplitude of the deformation of the finger, the time characteristics of deformation recovery, etc. can all be used as extracted features; and for torque characteristic data, the peak characteristics of the torque, the slope characteristics of the torque changing over time, etc. may be extracted. Through these feature extraction operations, the original sample parameters are converted into sample parameter features; multiple sample parameter features are used as input and the corresponding sample torque characteristic data are used as output to train the preset deep learning model; wherein, during the training process, the model attempts to predict the torque characteristics based on the input sample parameter characteristics, and then calculates the loss function by comparing 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 preset deep learning model meet the preset conditions, and a characteristic calculation model is obtained.

[0053] The preset condition may be that the number of iterations reaches a preset upper limit, or the error between the output predicted torque characteristic and the actual torque characteristic of the disconnector is less than a preset value, and then it is determined that the preset condition is met.

[0054] The above-mentioned preset deep learning model can be implemented by a neural network model, a support vector machine model or a random forest model, etc., and the selection of the specific 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 first calculated in a weighted manner, and the first friction parameter and the second friction parameter can be calculated in a weighted manner to obtain corresponding contact parameters and friction parameters, and further perform related operations of feature extraction of sample contact parameters, sample friction parameters, sample deformation parameters and sample torque characteristic data in each data pair.

[0056] S130. Control the drive component to control the target disconnector according to the torque characteristics.

[0057] When the driving component controls the target disconnector according to the torque characteristics, it can be clearly determined according to the torque used to control the opening and closing of the target disconnector, thereby achieving one-time operation of the target disconnector and improving work accuracy.

[0058] The drive assembly in this embodiment can be implemented by a servo motor. The servo motor has the characteristics of precise control and can adjust the action of the target disconnector according to the current corresponding target torque in the calculated torque characteristic to ensure that it operates with the appropriate torque at the right time.

[0059] The isolating switch control method provided in this embodiment first obtains the parameter information generated when multiple transmission components of the target isolating switch are working. The parameter information provided in this embodiment includes contact parameters, friction parameters and deformation parameters, which can reflect the component operation of the target isolating switch in the current state. Then, multiple parameters are input into the characteristic calculation model so that the characteristic calculation model can calculate the torque characteristics of the target isolating switch according to the input multiple parameters. The torque change of the target isolating switch in the current state can be better grasped through the torque characteristics. Finally, the control drive component controls the target isolating switch according to the obtained torque characteristics. The scheme provided in this embodiment calculates the parameters of each component corresponding to different isolating switches respectively through the characteristic calculation model, so that when controlling each isolating switch, it can be targetedly controlled according to the torque characteristics corresponding to the current isolating switch, which solves the problem of inadequate control when remotely controlling the target isolating switch by preset torque, and achieves the beneficial effects of improving the control accuracy of remote operation and improving work efficiency.

[0060] Figure 2 It is another flow chart of the isolating switch control method provided in the embodiment of the present application. The embodiment of the present application is optimized on the basis of the above embodiments. The specific optimization is as follows: This embodiment explains in detail the relevant implementation process of "determining target control information from torque characteristics according to current control time, and the target control information includes target control mode and target output torque" in the above embodiment.

[0061] See also Figure 2 The isolating switch control method of this embodiment includes but is not limited to the following steps:

[0062] S210. Obtain parameter information generated when multiple transmission components of the target disconnector are in operation.

[0063] The parameter information includes at least contact parameters, friction parameters and deformation parameters.

[0064] S220, inputting 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 target control information from the torque characteristics according to the current control time.

[0066] The target control information includes the target control mode and the target output torque.

[0067] In an understandable way, the torque characteristics of the target disconnector in this embodiment can be reflected by the relationship curve between time and output torque. Among them, the target control mode is used to indicate whether the target disconnector is currently controlled to close or open, and the target output torque is currently required to control the target disconnector. Controlling the target disconnector through the target output torque can ensure that the target disconnector can be operated in place at one time.

[0068] S240, controlling the drive component to control the target disconnector according to the target output torque in the target control mode.

[0069] When the driving assembly is implemented by a servo motor, the rotation of the servo motor can be controlled to drive the operating mechanism of the disconnector to move corresponding to the target output torque.

[0070] Specifically, the process of controlling the target isolating switch according to the torque characteristics of the control drive component provided in this embodiment can be implemented in the following manner: receiving target control information of the target isolating switch from the upper 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 can be understood by the driver, and the driver controls the rotation of the servo motor according to the instructions, thereby driving the operating mechanism of the isolating 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 isolating switch to form a circuit. In the power system, when it is necessary to connect a certain electrical equipment (such as a transformer, line, etc.) to the circuit for power supply or to connect different circuit parts, the isolating switch will be closed; the control opening is the opposite of the control closing operation, which refers to the operation of disconnecting the contacts of the isolating switch to cut off the circuit path. When it is necessary to inspect and maintain the electrical equipment or change the operation mode of the power system, the isolating switch will be opened.

[0072] Specifically, the above step S240 can be implemented in the following manner: when the target control mode is to control closing, the control drive component is controlled to operate in a first direction, so that during the operation according to the first direction, the control mechanism of the target disconnecting switch is controlled to produce a closing operation according to the target output torque. When the target control mode is to control opening, the control drive component is controlled to operate in a second direction, so that during the operation according to the second direction, the control mechanism of the target disconnecting switch is controlled to produce an opening operation according to the target output torque, and the first direction and the second direction are in opposite states.

[0073] Specifically, when the torque characteristics are reflected in the form of a curve showing the relationship between time and output torque, the control mode of the disconnector, the motor rotation direction of the drive component, and the function interval of the curve showing the relationship between time and output torque can be defined in advance. For example, when the control mode of the disconnector is to control closing, the corresponding motor rotation direction can be forward (first direction), which can be reflected in the curve showing the relationship between time and output torque as the curve corresponding to control closing occupies the first quadrant interval of the coordinate system (a positive value); conversely, when the control mode of the disconnector is to control opening, the corresponding motor rotation direction can be reverse (second direction), which can be reflected in the curve showing the relationship between time and output torque as the curve corresponding to control closing occupies the fourth quadrant interval of the coordinate system (a negative value); thereby, the control mechanism of the disconnector can be aligned based on the current relationship to perform closing or opening operations.

[0074] Another preferred embodiment, since the parameters of the transmission components of the isolating switch will change with the passage of time, in order to further achieve the purpose of accurately controlling the target isolating switch, the scheme provided in this embodiment, after the target isolating switch is controlled once according to the scheme provided in this embodiment, the model parameters of the characteristic calculation model will be adjusted according to the actual control results, so as to always maintain the accuracy of the output results of the characteristic calculation model.

[0075] Specifically, the isolating switch control solution provided in this embodiment also includes the following steps:

[0076] A control image of a target disconnecting switch is acquired based on a visual component, wherein the control image is obtained after a driving component controls the target disconnecting switch according to torque characteristics; feature extraction is performed on the control image to obtain control features; a control result of the target disconnecting switch is determined according to the control features; and when the control result does not meet the expected result, model parameters of a characteristic calculation model are adjusted according to the control result.

[0077] The visual component can be a visual device arranged at the target disconnector, such as a high-resolution industrial camera. After the control drive component controls the target disconnector according to the torque characteristics, the visual component can be controlled to obtain the control image generated after the target disconnector is controlled. The current control image should at least include the state information of the target disconnector under specific torque control, such as the contact finger engagement condition, contact finger engagement depth, and whether the conductive arm is straightened.

[0078] Before feature extraction is performed on the control image, the control image may be preprocessed. The current preprocessing may include grayscale processing to reduce the amount of data and simplify subsequent processing; it may also include image filtering, noise interference removal and other operations to obtain a high-precision control image for subsequent feature extraction operations.

[0079] Specifically, when extracting features from the control image, a preset extraction algorithm may be used to describe the control features of the disconnector, for example, the current control features may include the switch blade position, contact point state, contact finger engagement trajectory, etc. of the disconnector. Optionally, the preset extraction algorithm in this embodiment may be an edge detection algorithm.

[0080] Before determining the control result of the target disconnector according to the control feature, a mapping relationship between the control feature and the control result can be established in advance. For example, for the control of closing, if it is detected that the contact edge spacing is less than a certain threshold and the contact contact area is greater than a certain value, the closing operation is considered successful; otherwise, the closing is considered to have failed; for the control of opening, the position 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. Further, the extracted control features are compared with the pre-established mapping relationship to determine the control result of the target disconnector, that is, whether the operation is successful and reaches 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 it is determined that 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 that the contacts are fully in contact and the contact pressure is appropriate, but the actual control result shows that the contacts are not in full contact or the contact pressure is insufficient. Possible reasons include inaccurate torque calculation, wear of transmission components, deformation of contacts, etc. These reasons may be related to the parameters in the characteristic calculation model. The model parameters of the characteristic calculation model are adjusted according to the analysis results. For example, if it is believed that inaccurate torque calculation is the cause of poor control results, the parameters related to torque calculation, such as friction coefficient, load inertia, etc., can be adjusted in the model. If the problem is caused by wear of transmission components, the transmission efficiency and other parameters can be corrected according to the wear condition. The characteristic calculation model is updated by continuously adjusting the model parameters, so that in subsequent operations, the control of the disconnector according to the torque characteristics can be closer to the expected result.

[0083] This embodiment can timely discover potential problems by further analyzing the control results of the controlled target disconnector based on the visual component, thereby improving the accuracy and reliability of the disconnector operation. This method is of great significance for ensuring the safe and stable operation of the power system.
