Description

Technical Field

[0001] This application relates to the field of circuit breaker technology, and more specifically, to a circuit breaker control method and apparatus. Background Technology

[0002] In the actual application of circuit breakers, some protection products have specific requirements for the opening time of the circuit breaker. However, due to the limitation on the rotation speed of the circuit breaker motor, the opening speed of the circuit breaker is relatively slow.

[0003] In the existing technology, the circuit breaker’s fast tripping function is achieved by adding a tripping device. That is, by simplifying the structure of the circuit breaker’s motor part, only one position detection switch is used to detect whether the circuit breaker is closed, thereby realizing the circuit breaker’s closing function.

[0004] However, in this way, due to the inertia of the motor in the circuit breaker, the stopping position of the circuit breaker is uncertain, which can lead to the circuit breaker handle gear getting stuck. Summary of the Invention

[0027] Optionally, the step of updating the initial delay time to obtain the first updated delay time includes:

[0028] Based on a first preset duration, the initial delay time is updated to obtain the first updated delay time.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0061] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0062] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0063] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0064] To clearly describe the circuit breaker control method provided in the embodiments of this application, the circuit breaker will first be described in detail with reference to the accompanying drawings. Figure 1 A schematic diagram of the structure of a circuit breaker provided in this application embodiment. Figure 1 .like Figure 1 As shown, the circuit breaker 100 includes: a control device 101, a motor 102, and an actuator 103.

[0065] The control device 101 is connected to the control terminal of the motor 102 so as to control the motor 102 to work through the electrical signal sent by the control device 101 of the circuit breaker; one end of the motor 102 is connected to the actuator 103 so that the motor 102 can rotate to drive the actuator 103 to control the circuit breaker to perform a closing operation during the operation of the motor 102.

[0066] Among them, the control device 101 is used to execute the circuit breaker control method; the actuator 103 can also be called the mechanism system, which is a mechanical structure used to cooperate with the handle gear to close and open; the tripping device 104 is used to cooperate with the actuator to disconnect the handle gear, thereby realizing the circuit breaker's fast tripping function. Commonly used tripping devices 104 include, but are not limited to, overcurrent tripping devices or undervoltage tripping devices.

[0067] It should be noted that, in addition to the structures included in the circuit breaker 100 described above, the circuit breaker 100 also includes: a gear set 105, a micro switch 106, a handle gear 107, an operation button 108, a circuit board 109, and a memory chip 110, etc. Furthermore, it should be noted that the control device 101 is also connected to the control terminal of the tripping device 104, so that the electrical signal sent by the control device 101 controls the tripping device 104 to operate; the tripping device 104 is configured to cooperate with the other end of the actuator 103, so that the actuator 103 performs the circuit breaker tripping operation under the drive of the tripping device 104, thereby realizing the protection of the circuit breaker and the function of rapid tripping.

[0068] To clearly describe the circuit breaker 100 provided in the above embodiments, this application also provides a structural schematic diagram of another circuit breaker. Figure 2 A schematic diagram of the structure of a circuit breaker provided in this application embodiment. Figure 2 .

[0069] like Figure 2As shown, the control device 101 is located above the circuit board 109. When the control device 101 sends an electrical signal to the motor 102, it controls the motor 102 to rotate, which in turn drives the gear set 105 to rotate. The rotation of the gear set 105 then drives the circuit breaker handle gear 107 to rotate, which in turn drives the actuator 103 to rotate mechanically, thereby completing the closing operation of the circuit breaker. Alternatively, the control device 101 can provide an electrical signal to the tripping device 104, which can activate the rotation of the tripping device 104. Under the drive of the tripping device 104, the actuator 103 controls the handle gear 107 to perform the opening operation of the circuit breaker, thereby realizing the rapid opening function of the circuit breaker.

[0070] Among them, the micro switch 106, also known as the position detection switch, is used to detect the current position of the handle gear 107 of the circuit breaker 100. That is, when the handle gear 107 performs a closing operation, the position detection switch 106 is in the closed state, which can be represented as a valid signal of 1; when the handle gear 107 performs a opening operation, the position detection switch 106 is in the open state, which can be represented as a valid signal of 0.

[0071] The memory chip 110 in the circuit breaker is set on the circuit breaker's built-in circuit board 109 (such as PCB). This memory chip 110 can usually be represented as an EEPROM, which is not limited here.

[0072] When the handle gear 107 is in the closed position, the gear set 105 and the handle gear 107 are locked in a meshed state, meaning that the handle gear 107 cannot be freely opened by external operation, i.e., by the control operation button 108. Therefore, at this time, it is necessary to control the motor 102 to continue to rotate forward by a certain angle so that the gear set 105 and the handle gear 107 are disengaged. This disengagement state means that the gear set 105 and the handle gear 107 are no longer locked in a meshed state, and the handle gear 107 of the circuit breaker is in a free state, so that the circuit breaker can be freely opened by external operation such as the operation button 108.

[0073] Furthermore, the rotational speed of the circuit breaker's motor 102 is easily affected by various factors, such as the operating voltage of the motor 102, the impedance of the motor 102 itself, the dimensional fit between the gear sets 105, the rotational friction between the gear sets 105, the resistance and friction of the internal structural parts of the circuit breaker, etc. All of these factors can cause the circuit breaker's motor 102 to continue rotating due to inertia after the operating voltage is lost. Therefore, controlling the angle at which the motor 102 continues to rotate forward due to inertia is very important. If the angle at which the motor 102 continues to rotate forward due to inertia is too small, it is easy for the gear sets 105 to not completely disengage from the handle gear 107, and the handle gear 107 will still be in a locked state. If the angle at which the motor 102 continues to rotate forward due to inertia is too large, it is easy for the gear sets 105 to return to the locked position with the handle gear 107 after rotating one revolution.

[0074] Furthermore, since the handle gear 107 is in a locked state, a valid signal from the position detection switch 106 cannot be detected. In other words, the angle at which the motor 102 continues to rotate forward in this state can only be controlled based on the rotation delay time T of the motor 102. If the rotation delay time T of the motor 102 is longer, the rotation angle of the motor 102 will be larger; if the rotation delay time T of the motor 102 is shorter, the rotation angle of the motor 102 will be smaller.

[0075] Based on the above discussion, the delay time T for the motor 102 to continue rotating forward in the closing procedure of the circuit breaker is different for different circuit breaker products. Therefore, it is necessary to calibrate the delay time T for different circuit breaker products before they leave the factory.

[0076] Furthermore, since the delay time T for the motor 102 to continue rotating forward in the circuit breaker closing procedure in the above embodiments is different, this application provides a circuit breaker control method to solve the problem that the motor 102 in the circuit breaker closing procedure has an uncertain stopping position due to the inertia of the motor 102, which leads to the phenomenon of the circuit breaker handle gear 107 getting stuck.

[0077] The circuit breaker control method provided in this application can be executed by the control device in the circuit breaker. The circuit breaker control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. The circuit breaker control method provided in the embodiments of this application will be explained in detail below. Figure 3 A flowchart illustrating a circuit breaker control method provided in this application embodiment. Figure 1 .like Figure 3 As shown, the method may include:

[0078] S201. Obtain the initial delay time of the target circuit breaker.

[0079] S202. If the target circuit breaker meets the delay calibration conditions, then according to the initial delay time, control the actuator in the target circuit breaker to perform the delay calibration operation to obtain the target delay time.

[0080] Among them, the target circuit breaker meets the time delay calibration condition, that is, the target circuit breaker is the circuit breaker before leaving the factory, and the time delay T in the closing procedure of the circuit breaker before leaving the factory needs to be calibrated, or when the handle gear 107 is stuck during the normal use of the circuit breaker product, the circuit breaker control method provided in this application needs to be executed to solve the problem of the circuit breaker handle being stuck.

[0081] When the target circuit breaker meets the delay calibration conditions, the actuator in the target circuit breaker can be controlled to perform a delay calibration operation based on the initial delay time of the target circuit breaker, and the target delay time can be obtained. In order to solve the problem of the circuit breaker handle getting stuck in the future, the circuit breaker handle can be reset based on the target delay time.

[0082] This application provides a circuit breaker control method that obtains the initial delay time of a target circuit breaker. If the target circuit breaker meets the delay calibration conditions, the method controls the actuator in the target circuit breaker to perform a delay calibration operation based on the initial delay time, thereby obtaining the target delay time. Thus, this application can solve the problem of uncertainty in the stopping position of the circuit breaker due to the inertia of the motor in the circuit breaker by controlling the actuator in the target circuit breaker to perform a delay calibration operation and obtain the target delay time. It also solves the problem of the circuit breaker's handle gear jamming.

[0083] As an optional implementation, the circuit breaker control method provided in this application will be further explained below. Figure 4 A flowchart illustrating a circuit breaker control method provided in this application embodiment. Figure 2 .like Figure 4 As shown above, controlling the actuator in the target circuit breaker to perform a delay calibration operation based on the initial delay time to obtain the target delay time can include:

[0084] S301. If the target circuit breaker meets the delay calibration conditions, then based on the initial delay time of the target circuit breaker, control the actuator in the target circuit breaker to perform at least one round of the first closing and opening operation until the first closing and opening operation is performed and the circuit breaker is in place, thus obtaining the first delay time.

[0085] In one possible implementation, if the target circuit breaker meets the delay calibration conditions, then based on the initial delay time T0 of the target circuit breaker, the control device of the circuit breaker first sends an electrical signal to the motor 102 of the circuit breaker to control the motor 102 to rotate, and drive the connected gear set 105 to rotate, thereby driving the rotation of the handle gear 107 of the circuit breaker, which in turn drives the mechanical rotation of the actuator 103, and then controls the closing of the position detection switch 106 to complete the closing operation of the current circuit breaker. After the circuit breaker's closing operation is completed, the motor 102 rotates until the position switch is closed, then rotates for a delay time T, which is the initial delay time T0, and then stops. The control equipment then sends an electrical signal to the circuit breaker's tripping device 104 to control its rotation, which in turn drives the mechanical rotation of the actuator 103. The actuator 103 then controls the handle gear 107 to perform the circuit breaker's opening operation, thus completing the circuit breaker's closing operation. This allows the actuator 103 in the target circuit breaker to perform at least one round of the first closing and opening operation. When the first closing and opening operation is completed and the circuit breaker is fully open, the target circuit breaker's position detection switch 106 is successfully disconnected. At this time, the handle gear 107 is completely disengaged from the gear set 105, meaning the handle gear 107 is in a free state, allowing for free opening and closing operations of the circuit breaker via external operation such as the operation button 108. The first delay time T1 can be obtained after at least one round of the first closing and opening operation is completed, and this first delay time T1 can be regarded as the minimum delay time of the circuit breaker.

[0086] S302. Based on the first delay time, obtain the target delay time.

[0087] Optionally, the first delay time T1 obtained above can be used as the target delay time. Then, based on the target delay time of the target circuit breaker, the actuator in the target circuit breaker is controlled to perform a handle reset operation to solve the problem that the stopping position of the circuit breaker is uncertain due to the inertia of the motor in the circuit breaker. At the same time, it can also solve the problem that the handle gear of the target circuit breaker is stuck.

[0088] The circuit breaker control method provided in the embodiments of this application, based on an initial delay time, controls the actuator in the target circuit breaker to perform at least one round of first closing and opening operations until the circuit breaker is fully opened after the first closing and opening operations, thus obtaining a first delay time; based on the first delay time, a target delay time is obtained. Therefore, this application can solve the problem of uncertainty in the stopping position of the circuit breaker due to the inertia of the motor in the circuit breaker by controlling the actuator device in the target circuit breaker to perform a delay calibration operation and obtain the target delay time. Simultaneously, it can also solve the problem of the circuit breaker handle gear jamming in the target circuit breaker.

[0089] As an optional implementation, the circuit breaker control method provided in this application will be further explained below. Figure 5 A flowchart illustrating a circuit breaker control method provided in this application embodiment. Figure 3 .like Figure 5 As shown above, obtaining the target delay time based on the first delay time can include:

[0090] S401. Based on the first delay time, control the actuator in the target circuit breaker to perform at least one round of second closing and opening operations until the circuit breaker fails to open completely after performing the second closing and opening operations, and obtain the second delay time.

[0091] In one possible implementation, the actuator 103 in the target circuit breaker performs at least one round of second closing and opening operations again, and the specific process of the second closing and opening operation can refer to the specific process of the first closing and opening operation in the above embodiment, which will not be repeated here.

[0092] During the second closing and opening operation, based on the first delay time T1, the time during which the circuit breaker has not fully opened during the second closing and opening operation can be recorded as the second delay time T2 of the circuit breaker. That is, the second delay time T2 is the time during which the circuit breaker has not fully opened during the second closing and opening operation, and this second delay time T2 is recorded based on the first delay time T1; therefore, this second delay time T2 can be considered the maximum delay time of the circuit breaker.

[0093] S402. Based on the first delay time and the second delay time, obtain the target delay time.

[0094] In one possible implementation, the target delay time T of the target circuit breaker can be calculated using the following formula (1) based on the specific values ​​of the first delay time T1 and the second delay time T2 obtained from the above steps.

[0095] T = (T1 + T2) / 2 (1)

[0096] As can be seen from the above formula (1), the target delay time T of the target circuit breaker is the average of the maximum delay time and the minimum delay time of the circuit breaker.

[0097] The circuit breaker control method provided in the embodiments of this application, based on a first delay time, controls the actuator in the target circuit breaker to perform at least one round of second closing and opening operations until the circuit breaker fails to open completely after the second closing and opening operations, thus obtaining a second delay time; and obtains a target delay time based on the first delay time and the second delay time. Therefore, this application can solve the problem of uncertainty in the stopping position of the circuit breaker due to the inertia of the motor in the circuit breaker by controlling the actuator in the target circuit breaker to perform a delay calibration operation and obtain the target delay time. Simultaneously, it can also solve the problem of the circuit breaker handle gear jamming in the target circuit breaker.

[0098] As an optional implementation, the circuit breaker control method described above may further include:

[0099] Update the initial delay time of the target circuit breaker to the target delay time.

[0100] The target delay time is the delay time after the actuator in the target circuit breaker completes the circuit breaker closing operation and the motor stops rotating.

[0101] Specifically, when executing the circuit breaker control method, the initial delay time T0 corresponding to the storage chip (EEROM) in the target circuit breaker can be updated to the target delay time T. In the above embodiment, the update method can also be to directly replace the initial delay time T0 with the target delay time T; this is not a limitation.

[0102] The circuit breaker control method provided in the embodiments of this application, when the target circuit breaker meets the delay calibration conditions, can control the actuator in the target circuit breaker to perform at least one round of first closing and opening operations based on the initial delay time of the target circuit breaker, until the circuit breaker is fully opened after the first closing and opening operations are performed, thus obtaining a first delay time; and based on the first delay time, control the actuator in the target circuit breaker to perform at least one round of second closing and opening operations, until the circuit breaker is not fully opened after the second closing and opening operations are performed, thus obtaining a second delay time; then, based on the first delay time and the second delay time, a target delay time is determined, and the initial delay time of the target circuit breaker is updated to the target delay time, wherein the target delay time is the delay time after the actuator in the target circuit breaker performs the circuit breaker closing operation and the motor stops rotating. Therefore, this application can obtain a first delay time by performing the first closing and opening operation and then determining the first delay time by determining the first delay time after the circuit breaker has fully opened, and a second delay time by performing the second closing and opening operation and then determining the second delay time after the circuit breaker has not fully opened. This allows for the determination of the target delay time for different circuit breaker products. Furthermore, it allows for the determination of the rotation angle and speed of the actuator driven by the motor. By considering the rotation angle and speed of the actuator driven by the motor, the application addresses the uncertainty in the stopping position of the circuit breaker caused by motor inertia, thus resolving the problem of the target circuit breaker's handle gear jamming. Secondly, after updating the initial delay time of the target circuit breaker to the target delay time, the application can automatically activate the circuit breaker control method corresponding to the updated target delay time when the handle gear jams during normal use of the target circuit breaker, thereby improving the user experience.

[0103] As an optional implementation, this application also provides some possible implementation examples for determining the first delay time. Figure 6 A flowchart illustrating a circuit breaker control method provided in this application embodiment. Figure 4 .like Figure 6 As shown, in the above method, based on the initial delay time of the target circuit breaker, the tripping device in the target circuit breaker is controlled to perform at least one round of first closing and opening operations until the tripping device is in place after the first closing and opening operations are performed, thus obtaining the first delay time. This can include:

[0104] S501, The first closing operation is performed by controlling the actuator through the motor.

[0105] Specifically, the control device 101 of the circuit breaker provides an electrical signal to the motor 102 of the circuit breaker so that the motor 102 drives the gear set 105, which in turn drives the handle gear 107 to close. At the same time, the micro switch 106 can detect the valid signal 1, which in turn drives the actuator 103 to rotate mechanically, thereby controlling the first closing operation of the handle gear 107.

[0106] S502. If the first closing operation is detected and the closing is in place, after waiting for the initial delay time, control the motor to stop rotating.

[0107] Optionally, based on the initial delay time T0, when the actuator closes to the position after the first closing operation is detected, that is, when the gear set 105 of the target circuit breaker and the handle gear 107 are engaged and locked, the rotating motor 120 can stop rotating after the initial delay time T0.

[0108] S503, control the actuator to perform the first tripping operation.

[0109] The control device 101 provides an electrical signal to the tripping device 104 of the circuit breaker, so that the electrical signal controls the tripping device 104 to rotate, thereby causing the tripping device 104 to drive the actuator 103, and then control the handle gear 107 to perform the first automatic tripping operation.

[0110] S504. If it is detected that the circuit breaker has not been fully opened after the first opening operation, the initial delay time is updated to obtain the first updated delay time.

[0111] Optionally, if the tripping device 104 fails to trip during the first automatic tripping operation, i.e., the micro switch 106 fails to disconnect successfully, and the handle gear 107 of the circuit breaker is stuck, the handle gear 107 in the stuck state can be reset first, and then the initial delay time T0 can be updated to obtain the first updated delay time T01.

[0112] S505, The first closing operation is continued by controlling the actuator through the motor.

[0113] Specifically, when the handle gear 107 is stuck, the actuator can be controlled to continue performing the first closing operation after the first updated delay time T01. The specific process of the first closing and opening operation can be referred to the description in step S201, and will not be repeated here.

[0114] S506. If the first closing operation is detected to be completed after the closing is completed, the motor is controlled to stop rotating after the first updated delay time.

[0115] Optionally, based on the first updated delay time T01, when the actuator 103 closes the circuit after detecting that the first closing operation is to be continued, the rotating motor 120 may stop rotating after the first updated delay time T01.

[0116] S507, Control the actuator to continue performing the first tripping operation.

[0117] The control device 101 provides an electrical signal to the tripping device 104 of the circuit breaker, so that the electrical signal starts the rotation of the tripping device 104, thereby causing the tripping device 104 to drive the actuator 103 to perform the first automatic tripping operation.

[0118] S508. If the circuit breaker is detected to be in place after the first tripping operation is continued, the delay time after the first update is determined as the first delay time.

[0119] Optionally, when the tripping device 104 is in the tripped position during the first automatic tripping operation, i.e., the micro switch 106 is in the fully open state, i.e., the handle gear 107 of the circuit breaker is in the free state, the first updated delay time T01 can be determined as the first delay time T1.

[0120] It should be noted that in the above-described embodiment of the method for obtaining the first delay time, if the tripping device fails to trip after the first automatic tripping operation is detected, the circuit breaker is reset, and the initial delay time is updated for the first time. This process is repeated until the tripping device trips after the first automatic tripping operation is detected. The updated delay time is then determined as the first delay time. The cyclical nature of this process should not be construed as a limitation of the present invention. In other examples, implementation methods, or embodiments, options may be selected according to the present invention, and no specific limitations are made here.

[0121] The circuit breaker control method provided in the embodiments of this application executes a first closing operation through a motor-controlled actuator, and detects whether the first closing operation is completed. If the first closing operation is completed, the motor is stopped after an initial delay time, and the actuator is controlled to execute a first opening operation. If the first opening operation is not completed, the initial delay time is updated to obtain a first updated delay time. Then, the motor-controlled actuator continues to execute the first closing operation. If the continued execution of the first closing operation is completed, the motor is stopped after the first updated delay time, and the actuator is controlled to continue executing the first opening operation. If the continued execution of the first opening operation is completed, the first updated delay time is determined as the first delay time. Therefore, this application can update the delay time when the tripping device fails to trip during the first automatic tripping operation, so as to obtain the first updated delay time and replace the initial delay time of the target circuit breaker, thereby updating the delay time of the target circuit breaker and confirming the rotation delay time of the motor of the target circuit breaker, which is convenient for subsequent delay time calibration.

[0122] As an optional implementation, the first update of the initial delay time, as shown in step S404 above, to obtain the first updated delay time, may include:

[0123] Based on the first preset duration, the initial delay time is updated to obtain the first updated delay time.

[0124] Among them, the first preset duration T 预1 It can be set according to the actual situation, for example, the first preset duration T 预1 You can choose 10MS.

[0125] Specifically, according to the first preset duration T 预1 (e.g., 10MS), the initial delay time T0 is updated for the first time, and the delay time T01 after the first update can be calculated using the following formula (2).

[0126] T01 = T0 + T 预1 (2)

[0127] As an optional implementation, before updating the initial delay time according to the first preset duration as shown above, and obtaining the first updated delay time, the method may further include:

[0128] The first preset duration is determined based on the period of the preset AC signal.

[0129] The preset AC signal can be selected according to the actual situation. For example, the preset AC signal can be a 50Hz AC mains power. The period of the preset AC signal can also be selected according to the actual situation. For example, the period of the preset AC signal can be 20ms.

[0130] For example, when the preset AC signal is 50Hz mains power, the corresponding preset AC signal period is 20ms. Therefore, the period of this preset AC signal (e.g., 20ms) can be considered as the first preset duration T. 预1 Alternatively, the first preset duration T can be considered to be half the period of the preset AC signal, i.e., 10MS. 预1 And the first preset duration T 预1 (e.g., 10MS) is the minimum time for control processing.

[0131] It should be noted that, in the above embodiments, the first preset duration T... 预1 The confirmation should not be construed as a limitation on this application.

[0132] The circuit breaker control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 7 A flowchart illustrating a circuit breaker control method provided in this application embodiment. Figure 5 .like Figure 7 As shown, in the above method, based on the first delay time T 预1 The actuator in the target circuit breaker is controlled to perform at least one round of second closing and opening operations until the circuit breaker fails to open completely after the second closing and opening operations are performed, thus obtaining a second delay time, which may include:

[0133] S601, The second closing operation is performed by the motor control execution structure.

[0134] Specifically, the circuit breaker's control device provides an electrical signal to the circuit breaker's motor 102, causing the motor 102 to drive the gear set 105, which in turn drives the handle gear 107 to close. At the same time, the micro switch 106 can detect the valid signal 1, which in turn drives the actuator 103 to rotate mechanically, thereby controlling the second closing operation of the handle gear 107.

[0135] S602. If the second closing operation is detected and the closing is completed, after waiting for the first delay time, control the motor to stop rotating.

[0136] Optionally, based on the first delay time T1, when the actuator is closed after the second closing operation is detected, i.e., the micro switch 106 is in the closed state at this time, the controllable rotating motor 120 stops rotating after the first delay time T1.

[0137] S603, control the actuator to perform the second tripping operation.

[0138] Specifically, the control device 101 provides an electrical signal to the tripping device 104 of the circuit breaker, so that the electrical signal starts the rotation of the tripping device 104, thereby causing the tripping device 104 to drive the actuator 103 to perform the second opening operation.

[0139] S604. If the second tripping operation is detected and the tripping is completed, the first delay time is updated for the second time to obtain the second updated delay time.

[0140] Optionally, when the second tripping operation is detected and the tripping device is in place, the control device 101 provides an electrical signal to the tripping device 104, causing the tripping device 104 to drive the actuator 103 to perform the second automatic tripping operation of the target circuit breaker, thereby successfully disconnecting the position detection switch 106 of the target circuit breaker. At this time, the handle gear 107 is completely disengaged from the gear set 105, that is, the handle gear 107 is in a free state, and the circuit breaker can be freely opened and closed by external operation such as operation button 108. At this time, a second time update can be performed based on the first delay time T1 to obtain the second updated delay time T11.

[0141] S605, The second closing operation is continued by controlling the actuator through the motor.

[0142] Specifically, when the tripping device is in place after the second tripping operation is detected, an electrical signal is continued to be provided to the circuit breaker motor 102 through the second updated delay time T11 of the motor, so that the motor 102 drives the gear set 105, and then drives the handle gear 107 to close. At the same time, the micro switch 106 can detect the valid signal 1, and then drive the actuator 103 to rotate mechanically, thereby controlling the second closing operation of the handle gear 107.

[0143] S606. If the second closing operation is detected to be completed after the second closing operation is executed, the motor is controlled to stop rotating after waiting for the second updated delay time.

[0144] Optionally, based on the second updated delay time T11, when the actuator is detected to be in place after the second closing operation is continued, the rotating motor 102 can be stopped rotating after the second updated delay time T11.

[0145] S607. Control the actuator to continue performing the second tripping operation.

[0146] Specifically, the control device 101 provides an electrical signal to the tripping device 104 of the circuit breaker, so that the electrical signal starts the rotation of the tripping device 104, thereby causing the tripping device 104 to drive the actuator 103 to continue to perform the second tripping operation.

[0147] S608. If it is detected that the second tripping operation has not been completed after it is continued, the second updated delay time is determined as the second delay time.

[0148] Optionally, if the tripping device 104 fails to trip during the second tripping operation, i.e., the micro switch 106 fails to disconnect successfully, and the circuit breaker is in a stuck state with the handle gear 107, the stuck handle gear 107 can be reset first, and then the first delay time T1 can be updated to obtain the second updated delay time T11. Then, the second updated delay time T11 can be determined as the second delay time T2.

[0149] It should be noted that in the above-described embodiment of the method for obtaining the second delay time, if the tripping device is detected to have tripped after the second tripping operation, the first delay time is updated for the second time. This process is repeated until it is detected that the tripping device has not tripped after a second tripping operation is performed. The updated delay time is then determined as the second delay time. This cyclical process should not be construed as a limitation of the present invention. In other examples, implementations, or embodiments, options can be selected according to the present invention, and no specific limitations are made here.

[0150] The circuit breaker control method provided in the embodiments of this application executes a second closing operation through a motor control actuator; and detects whether the second closing operation is completed. If the second closing operation is completed, after waiting for a first delay time, the motor is controlled to stop rotating, and the actuator is controlled to execute a second opening operation. If the second opening operation is completed, the first delay time is updated to obtain a second updated delay time. The motor control actuator continues to execute the second closing operation. If the continued execution of the second closing operation is completed, after waiting for the second updated delay time, the motor is controlled to stop rotating, and the actuator continues to execute the second opening operation. If the continued execution of the second opening operation is not completed, the second updated delay time is determined as the second delay time. Therefore, this application can update the delay time by performing a second update when the tripping device is detected to be in place during the second tripping operation, thereby replacing the first delay time of the target circuit breaker and updating the delay time of the target circuit breaker. This allows the rotation delay time of the motor of the target circuit breaker to be confirmed, facilitating subsequent delay time calibration.

[0151] As an optional implementation, updating the first delay time as shown above to obtain the second updated delay time may include:

[0152] Based on the second preset duration, the first delay time is updated a second time to obtain the second updated delay time.

[0153] Specifically, according to the second preset duration T 预2 The second update of the first delay time T1 can be performed using the following formula (3) to calculate the second updated delay time T11.

[0154] T11 = T1 + T 预2 (3)

[0155] Among them, the second preset duration T 预2 Alternatively, it can be determined based on the period of a preset AC signal. The specific implementation method can be determined according to the first preset duration described above, which will not be elaborated here. That is, the second preset duration T... 预2 It can also be set according to the actual situation, for example, the second preset duration T 预2 You can choose 10MS.

[0156] As an optional implementation, as shown above, if the target circuit breaker meets the delayed reset condition, then based on the initial delay time of the target circuit breaker, the actuator in the target circuit breaker is controlled to perform at least one round of the first closing and opening operation. Until the first closing and opening operation is performed and the circuit breaker is fully opened, before obtaining the first delay time, the method may further include:

[0157] If the delay time of the target circuit breaker is the preset initial delay time, then the target circuit breaker is determined to meet the delay calibration condition; or,

[0158] If a delay verification operation for the target circuit breaker is received from an external device, then the target circuit breaker is determined to meet the delay calibration conditions; or,

[0159] If the tripping device of the target circuit breaker fails to trip after performing an automatic tripping operation, then the target circuit breaker is determined to meet the delay calibration condition.

[0160] Optionally, the target circuit breaker can meet the time-delay calibration conditions in three ways. In each case, as long as the time-delay calibration conditions are met, the circuit breaker control method can be implemented to prevent the circuit breaker from experiencing handle jamming (107) before it leaves the factory or during use. Examples are given below.

[0161] The first scenario: Before different circuit breaker products leave the factory, they need to undergo routine power-on tests.

[0162] Specifically, when writing parameters of the target circuit breaker into the EEROM (Extended Equivalent Memory ROM), the parameters of the target circuit breaker, such as the delay time, are generally set to a special value T0 and a default value FF. When the circuit breaker is inserted into the corresponding base, the control unit (MCU) on the base reads the data from the EEROM on the circuit breaker. If the read delay time T is the default value (FF), no calibration operation is performed; if the read delay time T is the set special value T0, the circuit breaker control method is executed, and the delay time T0 value corresponding to the EEROM is replaced with the T value. That is, when the delay time of the target circuit breaker is the preset initial delay time, it is determined that the target circuit breaker meets the delay calibration conditions.

[0163] Alternatively, in the second scenario, the user can also send a communication command for the delay verification operation of the target circuit breaker to the circuit breaker via an external device, so as to execute the circuit breaker control method. That is, upon receiving the delay verification operation input from the external device for the target circuit breaker, it is determined that the target circuit breaker meets the delay calibration conditions, thereby preventing the circuit breaker from jamming the handle gear 107.

[0164] Alternatively, in the third scenario: when the circuit breaker is in normal use, if the tripping device of the target circuit breaker fails to trip completely after performing an automatic tripping operation, i.e., the handle gear 107 becomes stuck, then the target circuit breaker is determined to meet the delay calibration conditions and the circuit breaker control method is automatically executed.

[0165] It should be noted that in the above embodiments, if the delay time T in the EEROM is the default value (FF), the indicator light on the target circuit breaker will flash accordingly to remind the user that there is currently no data in the EEROM of the target circuit breaker, in order to avoid the situation where data is missed in the EEROM during the production process of the circuit breaker product. Furthermore, it should be noted that there are many ways for the target circuit breaker in this application embodiment to remind the user that there is no data in its EEROM, and this should not be construed as a limitation of this application.

[0166] Based on the same inventive concept, this application also provides a circuit breaker delay reset device. Since the principle of the device in this application is similar to the circuit breaker control method described above in this application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.
