[0025] Figure 1 1 is a flow chart of an early warning method for a solid-state circuit breaker opening and closing coil according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0026] Step S101, determining the opening and closing coil of the solid-state circuit breaker to be detected.

[0027] In the technical solution provided in the above step S101 of the present invention, the opening and closing coil of the solid-state circuit breaker to be detected is determined.

[0028] In this embodiment, the solid-state circuit breaker opening and closing coil to be detected is determined. For example, the position and number of the opening and closing coil are determined by checking the circuit diagram of the circuit breaker. This is only an illustrative example and does not limit the specific method for determining the solid-state circuit breaker opening and closing coil to be detected.

[0029] Step S102, determining the three-dimensional characteristics of magnetic leakage and the three-dimensional characteristics of components based on the opening and closing coils of the solid-state circuit breaker.

[0030] In the technical solution provided in the above step S102 of the present invention, the leakage magnetic three-dimensional characteristics are used to indicate the three-dimensional characteristics of the spatial environment in which the solid-state circuit breaker opening and closing coil is located, and the component three-dimensional characteristics are used to indicate the three-dimensional characteristics of multiple components in the solid-state circuit breaker opening and closing coil.

[0031] In this embodiment, after the solid-state circuit breaker opening and closing coil to be detected is determined in step S101, the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics are determined according to the solid-state circuit breaker opening and closing coil.

[0032] Optionally, in order to determine the three-dimensional characteristics of magnetic leakage, the spatial environment of the solid-state circuit breaker opening and closing coil is obtained; the spatial environment is detected to determine the magnetic leakage signal of the spatial environment, wherein the magnetic leakage signal is used to indicate the change or abnormality of the magnetic field in the spatial environment. The magnetic leakage signal can also be called a global magnetic leakage signal.

[0033] For example, multi-point distributed magnetic leakage detection is performed on the spatial environment where the opening and closing coils of the solid-state circuit breaker are located to obtain the magnetic leakage signals of several position points corresponding to the spatial environment; based on the coordinate information of all the position points in the spatial environment, the magnetic leakage signals corresponding to all the position points are integrated to obtain the global magnetic leakage signal of the spatial environment.

[0034] Optionally, based on the magnetic leakage signal, a magnetic leakage distribution image of the space environment is determined, wherein the magnetic leakage distribution image is used to indicate changes in the intensity and direction of the magnetic field in the space environment; thereby determining the magnetic leakage three-dimensional characteristics of the magnetic leakage distribution image in the space environment.

[0035] For example, the global magnetic leakage signal is subjected to noise reduction preprocessing and digital conversion processing to obtain the global magnetic leakage magnetic field intensity distribution characteristic information of the spatial environment; based on the global magnetic leakage magnetic field intensity distribution characteristic information, a magnetic leakage distribution image of the spatial environment is constructed, and the three-dimensional spatial coordinate feature recognition is performed on the magnetic leakage distribution image to determine the spatial coordinate information of several three-dimensional spatial identification points of the solid-state circuit breaker opening and closing coils within the magnetic leakage distribution image, that is, the three-dimensional characteristics of the magnetic leakage.

[0036] Optionally, in order to determine the three-dimensional characteristics of magnetic leakage, the solid-state circuit breaker opening and closing coil is detected to determine the distribution state information of each component in the solid-state circuit breaker opening and closing coil, wherein the distribution state information is used to indicate the distribution of each component in the solid-state circuit breaker opening and closing coil. The distribution state information can also be called component distribution position information.

[0037] For example, an X-ray scanning test is performed on a solid-state circuit breaker opening and closing coil to obtain contour feature information of all components inside the solid-state circuit breaker opening and closing coil; based on the contour feature information of all components, the component distribution position information inside the solid-state circuit breaker opening and closing coil is determined; wherein the component distribution position information includes the distribution position information of the magnetic core and winding inside the solid-state circuit breaker opening and closing coil, that is, the distribution state information.

[0038] For another example, according to the contour feature information of all components, the component distribution position information inside the solid-state circuit breaker opening and closing coil is determined, including: using the following formula (1), according to the contour feature information of all components inside the solid-state circuit breaker opening and closing coil, determining whether the component is a magnetic core or a winding:

[0039]

[0040] Where J(a) indicates whether the ath element is a core or a winding; [X a (k),Y a (k)] represents the coordinate value of the kth feature point in the contour feature information of the ath element; [X a (p),Y a (p)] represents the coordinate value of the pth feature point in the contour feature information of the ath element; Q a represents the number of feature points in the contour feature information of the ath component; [lc min ,lc max ] represents the distance value range set between the two farthest contour feature points of the magnetic core; [lr min ,lr max ] represents the distance value range set between the two farthest contour feature points of the winding; ∈ represents the symbol; represents the maximum value of the distance between any two feature points in the contour feature information of the ath component; the position information of each component is determined according to the contour feature information of all components inside the solid-state circuit breaker opening and closing coil using the following formula (2):

[0041]

[0042] Among them, (x a ,y a ) represents the position coordinate point of the ath element; It means to sum the horizontal coordinates of all feature points in the contour feature information of the ath component; It means to sum the ordinates of all feature points in the contour feature information of the ath component; Represents the total number of all feature points in the contour feature information of the ath component. Using the following formula (3), the position information of each component is marked according to the result of determining whether it is a magnetic core or a winding, so that the marked position information set is used as the component distribution position information:

[0043]

[0044] in, Indicates the RGB value of the color used to mark the position coordinate point of the a-th component.

[0045] Optionally, a component distribution image of the opening and closing coil of the solid-state circuit breaker is generated according to the distribution state information; and three-dimensional features of the components of the component distribution image are determined.

[0046] For example, the component distribution position information is processed by three-dimensional spatial modeling to generate a component distribution image inside the solid-state circuit breaker opening and closing coil; wherein the component distribution image includes a three-dimensional distribution image of the magnetic core and winding inside the solid-state circuit breaker opening and closing coil, and the component distribution image is subjected to three-dimensional spatial coordinate feature recognition to determine the spatial coordinate information of several three-dimensional spatial identification points inside the component distribution image, that is, the three-dimensional features of the component.

[0047] Step S103, determining the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics.

[0048] In the technical solution provided in the above step S103 of the present invention, the leakage magnetic loss characteristic information may also be referred to as leakage magnetic loss change rate information.

[0049] In this embodiment, after the leakage magnetic three-dimensional characteristics and component three-dimensional characteristics of the solid-state circuit breaker opening and closing coil are determined in step S102, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics.

[0050] Optionally, based on the leakage magnetic field three-dimensional characteristics and the component three-dimensional characteristics, the leakage magnetic field strength information of each component in the solid-state circuit breaker opening and closing coil is determined, wherein the leakage magnetic field strength information is used to indicate the influence of the magnetic field generated by the solid-state circuit breaker opening and closing coil when it is working on the component; based on the leakage magnetic field strength information, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined, wherein the leakage magnetic loss characteristic information is used to indicate the magnetic energy loss of the component.

[0051] For example, the spatial coordinate information of all three-dimensional spatial identification points of the leakage magnetic distribution image and the component distribution image are matched one by one, that is, the leakage magnetic three-dimensional features and the component three-dimensional features are matched respectively, so as to integrate and overlap the leakage magnetic distribution image and the component distribution image into the same spatial coordinate system, thereby extracting the leakage magnetic field intensity information corresponding to each component under the solid-state circuit breaker opening and closing coil; and then analyzing the leakage magnetic field intensity information corresponding to each component to determine the leakage magnetic loss change rate information of each component.

[0052] Step S104, determining the working state of the opening and closing coil of the solid-state circuit breaker based on the leakage magnetic loss characteristic information.

[0053] In the technical solution provided in the above step S104 of the present invention, the working state of the opening and closing coil of the solid-state circuit breaker can at least be a normal working state or an abnormal working state.

[0054] In this embodiment, after the leakage magnetic loss characteristic information of the solid-state circuit breaker opening and closing coil is determined in step S103, the working state of the solid-state circuit breaker opening and closing coil is determined according to the leakage magnetic loss characteristic information.

[0055] Optionally, the leakage magnetic loss characteristic information is compared with a preset condition to obtain a comparison result; when the comparison result is that the leakage magnetic loss characteristic information does not meet the preset condition, it is determined that the working state of the solid-state circuit breaker opening and closing coil is an abnormal working state.

[0056] For example, based on the leakage magnetic loss change rate information of all components, it is determined whether the solid-state circuit breaker opening and closing coil can meet the preset magnetic field strength conditions within the preset time length; if the solid-state circuit breaker opening and closing coil cannot meet the preset magnetic field strength conditions within the preset time length, it is determined that the solid-state circuit breaker opening and closing coil is in an abnormal working state.

[0057] Step S105, in response to the working state being an abnormal working state, outputting warning information of the opening and closing coil of the solid-state circuit breaker.

[0058] In the technical solution provided in the above step S105 of the present invention, the warning information is used to indicate an abnormal working state.

[0059] In this embodiment, after the working state of the solid-state circuit breaker opening and closing coil is determined in step S104, when the working state is an abnormal working state, the warning information of the solid-state circuit breaker opening and closing coil is output.

[0060] For example, when the solid-state circuit breaker opening and closing coil is in an abnormal working state, an early warning notification message is sent to the terminal platform corresponding to the solid-state circuit breaker opening and closing coil; wherein the early warning notification message includes the device location information of the solid-state circuit breaker opening and closing coil.

[0061] It should be noted that the above embodiment can be implemented by a magnetic flux leakage warning system of a solid-state circuit breaker opening and closing coil.

[0062] In the above steps S101 to S105 of the present invention, the solid-state circuit breaker opening and closing coil to be detected is determined; based on the solid-state circuit breaker opening and closing coil, the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics are determined; based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined; based on the leakage magnetic loss characteristic information, the working state of the solid-state circuit breaker opening and closing coil is determined; in response to the working state being an abnormal working state, the warning information of the solid-state circuit breaker opening and closing coil is output. That is to say, the present invention determines the working state of the solid-state circuit breaker opening and closing coil by determining the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil to be detected, thereby realizing early warning prompts for the solid-state circuit breaker opening and closing coil according to the working state. Since the present invention can identify whether the fixed circuit breaker has abnormal conditions such as reduced response speed and sensitivity through early warning operations, the purpose of repairing the solid-state circuit breaker opening and closing coil is achieved, the technical problem of high maintenance cost of the solid-state circuit breaker opening and closing coil is solved, and the technical effect of reducing the maintenance cost of the solid-state circuit breaker opening and closing coil is achieved.

[0063] The above method of this embodiment is further introduced below.

[0064] As an optional implementation method, based on the solid-state circuit breaker opening and closing coil, the three-dimensional characteristics of the leakage magnetic field are determined, including: obtaining the spatial environment of the solid-state circuit breaker opening and closing coil; detecting the spatial environment to determine the leakage magnetic field signal of the spatial environment, wherein the leakage magnetic field signal is used to indicate the change or abnormality of the magnetic field in the spatial environment; based on the leakage magnetic field signal, determining the leakage magnetic field distribution image of the spatial environment, wherein the leakage magnetic field distribution image is used to indicate the change of the intensity and direction of the magnetic field in the spatial environment; determining the three-dimensional characteristics of the leakage magnetic field of the leakage magnetic field distribution image in the spatial environment.

[0065] In this embodiment, the spatial environment of the solid-state circuit breaker opening and closing coil is obtained; the spatial environment is detected to determine the leakage magnetic signal of the spatial environment; based on the leakage magnetic signal, the leakage magnetic distribution image of the spatial environment is determined; and the leakage magnetic three-dimensional characteristics of the leakage magnetic distribution image in the spatial environment are determined.

[0066] Optionally, the leakage magnetic signals corresponding to all position points of the solid-state circuit breaker opening and closing coils in the spatial environment are spatially continuously integrated to obtain a global leakage magnetic signal of the spatial environment, thereby achieving the purpose of quantitatively calibrating the magnetic field intensity distribution within the entire range of the spatial environment.

[0067] As an optional implementation method, based on the solid-state circuit breaker opening and closing coil, determining the three-dimensional characteristics of the components, including: detecting the solid-state circuit breaker opening and closing coil, determining the distribution status information of each component in the solid-state circuit breaker opening and closing coil, wherein the distribution status information is used to indicate the distribution of each component in the solid-state circuit breaker opening and closing coil; based on the distribution status information, generating a component distribution image of the solid-state circuit breaker opening and closing coil; and determining the three-dimensional characteristics of the components in the component distribution image.

[0068] In this embodiment, the solid-state circuit breaker opening and closing coil is detected to determine the distribution status information of each component in the solid-state circuit breaker opening and closing coil; based on the distribution status information, a component distribution image of the solid-state circuit breaker opening and closing coil is generated; and the three-dimensional characteristics of the components in the component distribution image are determined.

[0069] Optionally, the specific method for determining the three-dimensional characteristics of the component is as shown in the above formulas (1) to (3), which will not be repeated here.

[0070] Optionally, the aforementioned formula (1) is used to determine whether the component is a magnetic core or a winding according to the contour feature information of all the components inside the solid-state circuit breaker opening and closing coil, thereby facilitating the subsequent positioning of the distribution position information of the magnetic core and the winding. Then, the aforementioned formula (2) is used to determine the position information of each component according to the contour feature information of all the components inside the solid-state circuit breaker opening and closing coil, thereby integrating the contour feature information to obtain a position that can represent the component as its position information, thereby ensuring the accuracy and reliability of the system. Then, the aforementioned formula (3) is used to mark the position information of each component according to the determination result of whether it is a magnetic core or a winding, thereby using the marked position information set as the distribution position information of the component, and then using color for marking can intuitively show the distribution position of the magnetic core and the winding, and the color RGB value can also be used to well locate the distribution position information of the magnetic core and the winding inside the solid-state circuit breaker opening and closing coil.

[0071] As an optional implementation method, based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined, including: based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics, the leakage magnetic field strength information of each component in the solid-state circuit breaker opening and closing coil is determined, wherein the leakage magnetic field strength information is used to indicate the influence of the magnetic field generated by the solid-state circuit breaker opening and closing coil when it is working on the component; based on the leakage magnetic field strength information, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined, wherein the leakage magnetic loss characteristic information is used to indicate the magnetic energy loss of the component.

[0073] Optionally, since both the leakage magnetic three-dimensional features and the component three-dimensional features correspond to the spatial coordinate information of several preset structural identification points on the surface of the solid-state circuit breaker, the spatial coordinate information is associated with the spatial coordinate information, and the spatial coordinate information of all three-dimensional spatial identification points of the leakage magnetic distribution image and the component distribution image are matched one by one, so that the leakage magnetic distribution image and the component distribution image are integrated and overlapped in the same spatial coordinate system. In this way, the leakage magnetic distribution image and the component distribution image can be integrated and overlapped in the same spatial coordinate system, which is convenient for spatial comparison of the leakage magnetic distribution image and the component distribution image, and then the leakage magnetic field strength information corresponding to each component under the solid-state circuit breaker opening and closing coil is extracted, and then the leakage magnetic field strength information corresponding to each component is analyzed to determine the leakage magnetic loss change rate information of each component.

[0074] As an optional implementation method, based on the leakage magnetic loss characteristic information, the working state of the solid-state circuit breaker opening and closing coil is determined, including: comparing the leakage magnetic loss characteristic information with preset conditions to obtain a comparison result; in response to the comparison result that the leakage magnetic loss characteristic information does not meet the preset conditions, determining that the working state of the solid-state circuit breaker opening and closing coil is an abnormal working state.

[0078] In this embodiment, when the comparison result shows that the leakage magnetic loss characteristic information meets the preset condition, it is determined that the working state of the solid-state circuit breaker opening and closing coil is a normal working state.

[0079] For example, it is determined whether the solid-state circuit breaker opening and closing coil can meet the preset magnetic field strength condition within a preset time length; if so, it is determined that the solid-state circuit breaker opening and closing coil is in a normal working state.

[0080] It should be noted that the above embodiment can be implemented by a magnetic flux leakage warning system of a solid-state circuit breaker opening and closing coil.

[0081] In this embodiment, the solid-state circuit breaker opening and closing coil to be detected is determined; based on the solid-state circuit breaker opening and closing coil, the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics are determined; based on the leakage magnetic three-dimensional characteristics and the component three-dimensional characteristics, the leakage magnetic loss characteristic information of each component in the solid-state circuit breaker opening and closing coil is determined; based on the leakage magnetic loss characteristic information, the working state of the solid-state circuit breaker opening and closing coil is determined; in response to the working state being an abnormal working state, the warning information of the solid-state circuit breaker opening and closing coil is output.

[0083] At present, solid-state circuit breakers are important switch control components of switching power supply equipment. Solid-state circuit breakers perform magnetic induction work through the internal opening and closing coils, thereby controlling the switching of the corresponding circuits inside the switching power supply equipment, which has an important impact on the working reliability and precision of the switching power supply equipment. When the opening and closing coils of solid-state circuit breakers leak magnetic flux, the opening and closing coils will not be able to provide sufficient magnetic induction force or perform timely magnetic induction work to switch the circuit, causing serious switching delays in the switching power supply equipment, reducing the working sensitivity and time response speed of the switching power supply equipment.

[0084] In the related art, in order to ensure the normal operation of the switching power supply equipment, the prior art performs regular maintenance on the solid-state circuit breaker opening and closing coils.

Therefore, there is a technical problem of high maintenance cost of solid-state circuit breaker opening and closing coils. With respect to the above-mentioned technical problem of high maintenance cost of solid-state circuit breaker opening and closing coils, no effective solution has been proposed.
