[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0060] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0061] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0062] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0063] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

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

[0065] Among them, the control device 101 is connected to the control end 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; the motor 102 is connected to one end of the actuator 103 by transmission, so that when the motor 102 is working, the motor 102 rotates to drive the actuator 103 to control the circuit breaker to perform a closing operation.

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

[0067] It should be noted that, in addition to the structure included in the above-mentioned circuit breaker 100, 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 storage chip 110, etc. In addition, it should be noted that the control device 101 is also connected to the control end of the tripping device 104, so as to control the tripping device 104 to work through the electrical signal sent by the control device 101 of the circuit breaker; the tripping device 104 is arranged in cooperation with the other end of the actuator 103, so that the actuator 103 is driven by the tripping device 104 to perform the circuit breaker opening operation, and realize the protection of the circuit breaker and the rapid opening function.

[0068] In order to clearly describe the circuit breaker 100 provided in the above embodiment, the present application also provides a structural schematic diagram of another circuit breaker. Figure 2 A schematic diagram of a circuit breaker provided in an embodiment of the present application Figure 2 .

[0069] like Figure 2As shown, the control device 101 is arranged above the circuit board 109. When the control device 101 sends an electrical signal to the motor 102, the motor 102 is controlled to rotate, and then the motor 102 drives the gear set 105 to rotate, and then the rotation of the gear set 105 drives the rotation of the circuit breaker handle gear 107, and then drives the mechanical rotation of the actuator 103 to complete the closing operation of the circuit breaker; or, the control device 101 provides an electrical signal to the tripping device 104, and the electrical signal can activate the rotation of the tripping device 104, and 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, so as to realize the rapid opening function of the circuit breaker.

[0070] Among them, the micro switch 106 is also called the position detection switch, which 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 the closing operation, the position detection switch 106 is in a closed state, which can be represented by a valid signal of 1; when the handle gear 107 performs the opening operation, the position detection switch 106 is in a disconnected state, which can be represented by a valid signal of 0.

[0071] The memory chip 110 in the circuit breaker is arranged on a circuit board 109 (such as a PCB) built into the circuit breaker. The memory chip 110 can generally be represented as an EEROM, which is not limited here.

[0072] When the handle gear 107 is in the closed state, the gear group 105 and the handle gear 107 are in a meshing and locked state, that is, the handle gear 107 cannot be freely opened by external operation, that is, the control operation button 108 can be used to freely open the handle gear 107. 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 group 105 and the handle gear 107 are in a disengaged state. The disengaged state means that the gear group 105 and the handle gear 107 are no longer in a meshing and locked state, and the handle gear 107 of the circuit breaker is in a free state, and the circuit breaker can be freely opened by external operation such as the operation button 108.

[0073] Furthermore, since the rotation speed of the motor 102 of the circuit breaker is easily affected by many factors, such as the working voltage of the motor 102, the impedance of the motor 102 itself, the size matching between the gear sets 105, the rotation friction between the gear sets 105, the resistance of the internal structural parts of the circuit breaker, the friction, etc., the motor 102 of the circuit breaker will continue to rotate due to inertia after losing the working voltage. Therefore, it is very important to control the angle at which the motor 102 continues to rotate forward due to inertia. If the angle at which the motor 102 continues to rotate forward due to inertia is too small, it is easy to cause the gear set 105 to not completely disengage from the handle gear 107, and the handle gear 107 is still 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 to cause the gear set 105 to return to the position locked with the handle gear 107 again after rotating one circle.

[0074] Moreover, since the handle gear 107 is in a locked state, the effective signal of the position detection switch 106 cannot be detected, that is, the angle at which the motor 102 continues to rotate forward in this state can only be controlled according to 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 is larger; if the rotation delay time T of the motor 102 is shorter, the rotation angle of the motor 102 is smaller.

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

[0076] Furthermore, based on the fact that the delay time T for the motor 102 to continue rotating forward in the closing procedure of the circuit breaker in the above-mentioned embodiment is different, an embodiment of the present application provides a circuit breaker control method to solve the problem that the motor 102 in the circuit breaker closing procedure has an uncertainty in the stop position due to the inertia problem of the motor 102, and the handle gear 107 of the circuit breaker is stuck.

[0077] The circuit breaker control method provided in the embodiment of the present application can be executed by a control device in the circuit breaker. The circuit breaker control method provided in the above embodiment of the present application is explained and illustrated in detail in conjunction with the accompanying drawings. The circuit breaker control method provided in the embodiment of the present application is explained in detail as follows: Figure 3 A schematic diagram of a circuit breaker control method provided in an embodiment of the present application Figure 1 .like Figure 3 As shown, the method may include:

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

[0079] S202: If the target circuit breaker meets the delay calibration condition, the actuator in the target circuit breaker is controlled to perform a delay calibration operation according to the initial delay time to obtain a target delay time.

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

[0082] The embodiment of the present application provides a circuit breaker control method, which obtains the initial delay time of the target circuit breaker; if the target circuit breaker meets the delay calibration condition, the actuator in the target circuit breaker is controlled to perform the delay calibration operation according to the initial delay time to obtain the target delay time. Therefore, the present application can solve the problem of uncertainty in the stop 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 the delay calibration operation and obtain the target delay time, and at the same time, it can also solve the problem of the handle gear of the target circuit breaker being stuck.

[0083] As an optional implementation manner, the circuit breaker control method provided in the embodiment of the present application is further explained as follows: Figure 4 A schematic diagram of a circuit breaker control method provided in an embodiment of the present application Figure 2 .like Figure 4 As shown above, according to the initial delay time, controlling the actuator in the target circuit breaker to perform the delay calibration operation to obtain the target delay time may include:

[0084] S301. If the target circuit breaker meets the delay calibration condition, 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 first closing and opening operations until the circuit breaker is opened in place after the first closing and opening operations are performed, thereby obtaining a first delay time.

[0085] In one possible implementation, if the target circuit breaker meets the delay calibration condition, 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 rotation of the motor 102, and drive the rotation of the connected gear set 105, so as to drive the rotation of the handle gear 107 of the circuit breaker, and then drive the mechanical rotation of the actuator 103, and then control the closing of the position detection switch 106 to complete the closing operation of the current circuit breaker. After the closing operation of the circuit breaker is completed, the motor 102 rotates until the position switch is closed, and then rotates for a delay time T, which is the initial delay time T0 and then stops. Then the control device sends an electrical signal to the tripping device 104 of the circuit breaker to control the rotation of the tripping device 104, thereby driving the mechanical rotation of the actuator 103, and the actuator 103 controls the handle gear 107 to perform the opening operation of the circuit breaker to complete the closing operation of the circuit breaker, so that the actuator 103 in the target circuit breaker can perform at least one round of the first closing and opening operation. When the opening is in place after the first closing and opening operation is performed, the position detection switch 106 of the target circuit breaker can be disconnected successfully. At this time, the handle gear 107 is in a completely disengaged state from the gear set 105, that is, the handle gear 107 is in a free state, and the free closing and opening operation of the circuit breaker can be performed through external operations such as the operation button 108. That is, after at least one round of first closing and opening operations is completed, the first delay time T1 can be obtained, and the first delay time T1 can be considered as the minimum delay time of the circuit breaker.

[0086] S302: Obtain a target delay time according to the first delay time.

[0087] Optionally, the first delay time T1 obtained as described above can be used as the target delay time, and 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 of uncertainty in the stop position of the circuit breaker due to the inertia of the motor in the circuit breaker. At the same time, the problem of the handle gear of the target circuit breaker being stuck can also be solved.

[0088] The circuit breaker control method provided by the embodiment of the present application controls 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, until the opening is in place after the first closing and opening operations are performed, and the first delay time is obtained; according to the first delay time, the target delay time is obtained. Therefore, the present application can solve the problem of uncertainty in the stop 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 and obtaining the target delay time, and at the same time, it can also solve the problem of the handle gear of the target circuit breaker being stuck.

[0089] As an optional implementation manner, the circuit breaker control method provided in the embodiment of the present application is further explained as follows: Figure 5 A schematic diagram of a circuit breaker control method provided in an embodiment of the present application Figure 3 .like Figure 5 As shown, obtaining the target delay time according to the first delay time as shown above may 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 is not fully opened after the second closing and opening operations are performed, thereby obtaining a second delay time.

[0091] In one possible implementation, the actuator 103 in the target circuit breaker is controlled to perform 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 execution of the second closing and opening operation, the time during which the circuit breaker is not fully opened during the execution of the second closing and opening operation can be recorded based on the first delay time T1 as the second delay time T2 of the circuit breaker. That is, the second delay time T2 is the time during the second closing and opening operation during which the circuit breaker is not fully opened, and the second delay time T2 is recorded based on the first delay time T1, that is, the second delay time T2 can be considered as the maximum delay time of the circuit breaker.

[0093] S402: Obtain a target delay time according to the first delay time and the second delay time.

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

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

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

[0097] The circuit breaker control method provided by the embodiment of the present application controls the actuator in the target circuit breaker to perform at least one round of second closing and opening operations based on the first delay time, until the second closing and opening operations are performed but the circuit breaker is not opened in place, and the second delay time is obtained; the target delay time is obtained according to the first delay time and the second delay time. Therefore, the present application can solve the problem of uncertainty in the stop 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 and obtaining the target delay time, and at the same time, can also solve the problem of the handle gear of the target circuit breaker being stuck.

[0098] As an optional implementation, the circuit breaker control method as shown 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 for the motor to stop rotating after the actuator in the target circuit breaker executes the circuit breaker closing operation.

[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. The updating method in the above embodiment can also be to directly replace the initial delay time T0 with the target delay time T, which is not limited here.

[0102] The circuit breaker control method provided in the embodiment of the present application can control the actuator device 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 when the target circuit breaker meets the delay calibration condition, until the opening is in place after the first closing and opening operation is performed, and a first delay time is obtained; 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 opening is not in place after the second closing and opening operation is performed, and a second delay time is obtained; then, according to the first delay time and the second delay time, determine the target delay time, and update the initial delay time of the target circuit breaker to the target delay time, and the target delay time is: the delay time for the motor to stop rotating after the actuator in the target circuit breaker performs the circuit breaker closing. Thus, the present application can obtain the first delay time by executing the first closing and opening operation after the opening is in place and obtain the second delay time by executing the second closing and opening operation after the opening is not in place, and then confirm the target delay time of the circuit breaker, and confirm the target delay time of the circuit breaker according to the minimum delay time of the circuit breaker represented by the first delay time and the maximum delay time of the circuit breaker represented by the second delay time, so as to realize the confirmation of the target delay time for different circuit breaker products, and then confirm the size of the rotation angle of the actuator driven by the motor and the rotation speed of the motor, so as to solve the problem of the uncertainty of the stop position of the circuit breaker caused by the inertia of the motor in the circuit breaker according to the size of the rotation angle of the actuator driven by the motor and the rotation speed of the motor, and then solve the problem of the handle gear of the target circuit breaker in the circuit breaker. Secondly, after the initial delay time of the target circuit breaker is updated to the target delay time, when the handle gear of the circuit breaker is stuck during the normal use of the target circuit breaker, the circuit breaker control method corresponding to the updated target delay time can be automatically started to improve the user experience.

[0103] As an optional implementation, the embodiment of the present application also provides some possible implementation examples for determining the first delay time. Figure 6 A schematic diagram of a circuit breaker control method provided in an embodiment of the present application Figure 4 .like Figure 6 As shown, in the above method, based on the initial delay time of the target circuit breaker, controlling the trip device in the target circuit breaker to perform at least one round of the first closing and opening operation until the trip device is fully opened after the first closing and opening operation is performed, and obtaining the first delay time may include:

[0104] S501. Execute a first closing operation by controlling an actuator through a 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, and then drives the handle gear 107 to close. At the same time, the micro switch 106 can detect the effective signal 1, and then drive the actuator 103 to rotate mechanically, thereby controlling the first closing operation of the handle gear 107.

[0106] S502: If it is detected that the first closing operation is completed, the motor is controlled to stop rotating after waiting for an initial delay time.

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

[0108] S503, controlling the actuator to perform the first opening 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 further controlling the handle gear 107 to perform the first automatic opening operation.

[0110] S504: If it is detected that the switch is not fully opened after the first opening operation, the initial delay time is first updated to obtain a first updated delay time.

[0111] Optionally, during the first automatic opening operation detected, the tripping device 104 fails to open the circuit, that is, the micro switch 106 fails to disconnect successfully, that is, the handle gear 107 of the circuit breaker is in a stuck state at this time, and the handle gear 107 in the stuck state can be reset first, and then the initial delay time T0 is updated for the first time to obtain the first updated delay time T01.

[0112] S505. Continue to execute the first closing operation by controlling the actuator through the motor.

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

[0114] S506: If it is detected that the first closing operation is continued and the closing operation is completed, the motor is controlled to stop rotating after waiting for the first updated delay time.

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

[0116] S507. Control the actuator to continue to perform the first opening 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 opening operation.

[0118] S508: If it is detected that the first opening operation is continued and the opening is completed, a first updated delay time is determined as the first delay time.

[0119] Optionally, when it is detected that the first automatic opening operation is continuing, when the tripping device 104 is in the opening position, that is, the micro switch 106 is in a completely disconnected state, that is, the handle gear 107 of the circuit breaker is in a free state at this time, the first updated delay time T01 can be determined as the first delay time T1.

[0120] It should be noted that in the above-mentioned embodiment of the method used for obtaining the first delay time, if it is detected that the tripping device is not fully opened after the first automatic opening operation, the circuit breaker is reset, and the initial delay time is first updated, and the cycle is repeated until it is detected that the tripping device is fully opened after the first automatic opening operation is continued, and the first updated delay time is determined as the first delay time. The cycle of the above process should not be understood as a limitation of the present invention. In other examples, implementation methods or embodiments, it can be selected according to the present invention and is not specifically limited here.

[0121] The circuit breaker control method provided by the embodiment of the present application performs a first closing operation by controlling an actuator through a motor, and detects whether the first closing operation is in place; if it is detected that the closing operation is in place after the first closing operation, after waiting for an initial delay time, the motor is controlled to stop rotating, and the actuator is controlled to perform a first opening operation; if it is detected that the opening operation is not in place after the first opening operation, the initial delay time is updated for a first time to obtain a first updated delay time; then the first closing operation is continued to be performed by controlling the actuator through the motor; if it is detected that the closing operation is in place after the continued first closing operation is performed, after waiting for the first updated delay time, the motor is controlled to stop rotating; the actuator is controlled to continue to perform the first opening operation; if it is detected that the opening operation is in place after the continued first opening operation is performed, the first updated delay time is determined as the first delay time. Therefore, the present application can perform a first update of the delay time when it is detected that the tripping device has not opened in the first automatic opening operation process to obtain a first updated delay time, and then replace the initial delay time of the target circuit breaker to achieve the update of the delay time of the target circuit breaker, and then confirm 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, performing a first update on the initial delay time as shown in the above step S404 to obtain a first updated delay time may include:

[0123] According to the first preset time length, the initial delay time is first updated to obtain a first updated delay time.

[0124] Among them, the first preset time length T 预1 It can be set according to actual conditions. For example, the first preset time length T 预1 It can be selected as 10MS.

[0125] Specifically, according to the first preset time length T 预1 (such as 10MS), the initial delay time T0 is first updated, 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 manner, before performing a first update on 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] A first preset duration is determined according to a cycle of a preset alternating current signal.

[0129] Among them, the preset AC signal can be selected according to actual conditions, for example, the preset AC signal can be 50HZ AC power; the period of the preset AC signal can also be selected according to actual conditions, for example, the period of the preset AC signal can be 20MS.

[0130] For example, when the preset AC signal is 50 Hz mains power, the corresponding preset AC signal period is 20 MS, and the period of the preset AC signal (such as 20 MS) can be considered as the first preset time length T 预1 Or it can be considered that half of the cycle of the preset AC signal, that is, 10MS is the first preset duration T 预1 , and the first preset time length T 预1 (such as 10MS) is the minimum time for control processing.

[0131] It should be noted that in the above embodiment, the first preset time length T 预1 The confirmation should not be understood as a limitation of this application.

[0132] The circuit breaker control method provided in the above embodiment of the present application is explained and illustrated in detail as follows in conjunction with the accompanying drawings. Figure 7 A schematic diagram of a circuit breaker control method provided in an embodiment of the present application Figure 5 .like Figure 7 As shown, in the above method, based on the first delay time T 预1 , controlling the actuator in the target circuit breaker to perform at least one round of the second closing and opening operation until the circuit breaker is not fully opened after the second closing and opening operation is performed, and obtaining the second delay time may include:

[0133] S601. Execute a second closing operation through a motor control execution structure.

[0134] Specifically, the control device 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, and then drives the handle gear 107 to close. At the same time, the micro switch 106 can detect the effective signal 1, and then drive 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 in place, the motor is controlled to stop rotating after waiting for the first delay time.

[0136] Optionally, based on the first delay time T1, when the actuator is detected to be in full closing position after the second closing operation, that is, the micro switch 106 is in a closed state at this time, the rotating motor 120 can be controlled to stop rotating after the first delay time T1.

[0137] S603, controlling the actuator to perform a second opening operation.

[0138] Specifically, an electrical signal is provided to the tripping device 104 of the circuit breaker through the control device 101, 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 it is detected that the second opening operation is completed, the first delay time is updated for a second time to obtain a second updated delay time.

[0140] Optionally, when the tripping device is opened in place after the second opening operation is detected, the control device 101 provides an electrical signal to the tripping device 104, so that the tripping device 104 drives the actuator 103 to perform the second automatic opening 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 the operation button 108. At this time, the second time update can be performed on the basis of the first delay time T1 to obtain the second updated delay time T11.

[0141] S605. Continue to execute the second closing operation through the motor-controlled actuator.

[0142] Specifically, when the trip device is detected to be in place after the second opening operation, an electrical signal is continued to be provided to the motor 102 of the circuit breaker through the control device 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 effective 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 it is detected that the second closing operation is continued and the closing operation is completed, 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 it is detected that the actuator is fully closed after the second closing operation is continued, the rotating motor 102 can be stopped after the second updated delay time T11.

[0145] S607. Control the actuator to continue to perform the second opening 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 enabling the tripping device 104 to drive the actuator 103 to continue to perform the second opening operation.

[0147] S608: If it is detected that the second opening operation is not completed, a second updated delay time is determined as the second delay time.

[0148] Optionally, when it is detected that the second opening operation is being continued and the tripping device 104 has not opened in place, that is, the micro switch 106 fails to disconnect, that is, the circuit breaker is in a stuck state with the handle gear 107 at this time, the stuck handle gear 107 can be reset first, and then the first delay time T1 can be updated for a second time to obtain the second updated delay time T11, and the second updated delay time T11 can be determined as the second delay time T2.

[0149] It should be noted that in the above-mentioned embodiment of the method used for obtaining the second delay time, if it is detected that the tripping device is in place after the second opening operation, and the first delay time is updated for the second time, the cycle is repeated until it is detected that the tripping device is not in place after the second opening operation is continued, and the second updated delay time is determined as the second delay time. The cycle of the above process should not be understood as a limitation of the present invention. In other examples, implementation methods or embodiments, it can be selected according to the present invention and is not specifically limited here.

[0150] The circuit breaker control method provided by the embodiment of the present application performs a second closing operation through a motor control execution structure; and detects whether the second closing operation is in place, if it is detected that the closing is in place after the second closing operation, after waiting for a first delay time, the motor is controlled to stop rotating, and the actuator is controlled to perform a second opening operation; if it is detected that the opening is in place after the second opening operation, the first delay time is updated for a second time to obtain a second updated delay time; the second closing operation is continued to be performed by the motor control actuator; if it is detected that the closing is in place after the continued second closing operation, the motor is controlled to stop rotating after waiting for the second updated delay time; the actuator is controlled to continue to perform the second opening operation; if it is detected that the opening is not in place after the continued second opening operation, the second updated delay time is determined as the second delay time. Therefore, the present application can perform a second update of the delay time when it is detected that the trip device is in place during the second opening operation to obtain a second updated delay time, and then replace the first delay time of the target circuit breaker to achieve the update of the delay time of the target circuit breaker, and then confirm the rotation delay time of the motor of the target circuit breaker, which is convenient for subsequent delay time calibration.

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

[0152] According to the second preset time length, the first delay time is updated for a second time to obtain a second updated delay time.

[0153] Specifically, according to the second preset time length T 预2 , the first delay time T1 is updated for the second time, and the delay time T11 after the second update can be calculated using the following formula (3).

[0154] T11=T1+T 预2 (3)

[0155] Among them, the second preset time length T 预2 It can also be determined according to the cycle of the preset alternating current signal. The specific implementation method can be determined according to the first preset duration recorded above, which will not be repeated here. 预2 It can also be set according to actual conditions. For example, the second preset time length T 预2 It can be selected as 10MS.

[0156] As an optional implementation, as shown above, if the target circuit breaker meets the delayed reset condition, 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 opening is in place before the first delay time is obtained. The method may also include:

[0157] If 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 condition; or,

[0158] If a delay calibration operation for the target circuit breaker inputted by an external device is received, it is determined that the target circuit breaker meets the delay calibration condition; or,

[0159] If the trip device of the target circuit breaker does not open in place after performing the automatic opening operation, it is determined that the target circuit breaker meets the delay calibration condition.

[0160] Optionally, the target circuit breaker can meet the delay calibration conditions in three ways, and in each case, as long as the delay calibration conditions of the target circuit breaker are met, the circuit breaker control method can be executed to prevent the circuit breaker product from having a handle stuck before the circuit breaker product leaves the factory or during the use of the circuit breaker product. Examples are given below to illustrate each.

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

[0162] Specifically, when writing the parameters of the target circuit breaker to the storage chip (EEROM), 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 in the storage chip (EEROM) on the section circuit breaker. If the delay time T read is the default value (FF), no calibration operation is performed; if the delay time T read is the set special value T0, the circuit breaker control method is executed, and the delay time T0 value corresponding to the storage chip (EEROM) is replaced by 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 condition.

[0163] Alternatively, in the second case, the user may also send a communication command for a delay verification operation on the target circuit breaker to the circuit breaker through an external device, so as to execute the circuit breaker control method, that is, upon receiving the delay verification operation on the target circuit breaker input by the external device, it is determined that the target circuit breaker meets the delay calibration condition, thereby preventing the handle gear 107 of the circuit breaker from getting stuck.

[0164] Or, in the third case, when the circuit breaker product is in normal use, after the tripping device of the target circuit breaker performs the automatic opening operation, if the tripping device fails to open in place, that is, the handle gear 107 is stuck, it is determined that the target circuit breaker meets the delay calibration condition, and the circuit breaker control method is automatically executed.

[0165] It should be noted that in the above embodiment, if the delay time T in the storage chip (EEROM) is the default value (FF), the indicator light on the target circuit breaker will flash accordingly to remind the user that there is no data in the storage chip (EEROM) of the target circuit breaker, so as to avoid the situation where the storage chip (EEROM) data is omitted during the production process of the circuit breaker product. In addition, it should be noted that there are many ways for the target circuit breaker in the embodiment of the present application to remind the user that there is no data in the storage chip (EEROM) where it is located, which cannot be understood as a limitation of the present application.

[0166] Based on the same inventive concept, a circuit breaker delayed reset device is also provided in the embodiment of the present application. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above-mentioned circuit breaker control method in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
