[0058] In the related art, a reclosing circuit breaker is a circuit breaker that automatically restarts a circuit and is used for protection and control in power systems. It disconnects the circuit when a short circuit occurs, and then automatically attempts to reclose within a set time to restore power supply.

[0059] Traditional reclosing abnormality detection of reclosing circuit breakers relies on manual detection, which is a tedious and complicated process, resulting in the inability to timely detect problems with the reclosing circuit breaker, which in turn leads to low detection efficiency of the reclosing circuit breaker.

[0060] To solve the above problems, an embodiment of the present application provides a reclosing abnormality detection for a reclosing circuit breaker.

[0061] In the method, firstly, by monitoring the reclosing detection and analysis of the reclosing circuit breaker by the reclosing detection device and the control device, the reclosing circuit breaker can be analyzed in real time, which reduces the need for manual intervention, reduces the risk of human operation errors, and helps to improve the subsequent detection efficiency of the reclosing. Then, by obtaining whether the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker, it can ensure that the coordination between the reclosing detection device and the control device is normal, avoid missed detection and false detection, and then provide data support for the subsequent timely identification of problems or abnormalities in the detection process, which helps to improve the subsequent detection efficiency of the reclosing. Finally, the control device analyzes the detection business and the detection analysis information to obtain the detection result, which helps to quickly determine whether the reclosing circuit breaker is faulty, thereby reducing the reaction time of manual intervention and helping to improve the detection efficiency of the reclosing.

[0062] The method for detecting the abnormal reclosing of a reclosing circuit breaker provided in the embodiment of the present application can be applied to a reclosing abnormality detection device. At this time, the reclosing abnormality detection device is the executor of the method for detecting the abnormal reclosing of a reclosing circuit breaker provided in the embodiment of the present application. The embodiment of the present application does not impose any restriction on the specific type of the reclosing abnormality detection device.

[0063] For example, the reclosing abnormality detection device may include a reclosing detection device and a control device. The reclosing detection device may include a current detection device (such as a digital ammeter), a voltage detection device (such as a digital voltmeter), and a frequency detection device (such as a frequency meter or a frequency analyzer). For example, the current detection device is used to detect the current value of the reclosing switch. The voltage detection device is used to detect the voltage value of the reclosing switch. The frequency detection device is used to detect the reclosing operation frequency of the reclosing switch. For example, the control device can identify the short circuit condition of the reclosing switch based on the current value. The control device can also identify abnormal fluctuations or instability of the reclosing switch based on the voltage value. The control device can also analyze whether the reclosing operation of the reclosing switch is too frequent based on the reclosing operation frequency of the reclosing switch.

[0064] For example, the control device can be a mobile phone, tablet computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, desktop computer, computing device or computer connected to a wireless modem, laptop computer, handheld communication device, handheld computing device, etc.

[0065] In order to better understand the method for detecting the reclosing abnormality of a reclosing circuit breaker provided in the embodiment of the present application, the specific implementation process of the method for detecting the reclosing abnormality of a reclosing circuit breaker provided in the embodiment of the present application is exemplarily introduced below.

[0066] Figure 1A schematic flow chart of a method for detecting abnormal reclosing of a reclosing circuit breaker provided in an embodiment of the present application is shown. The method for detecting abnormal reclosing of a reclosing circuit breaker includes:

[0067] S100, the control device monitors the detection service, wherein the detection service is used to instruct the reclosing detection device and the control device to perform reclosing detection analysis on the reclosing circuit breaker.

[0068] It can be understood that a service monitoring mechanism can be set up to monitor the detection service. A timed task can also be set to regularly monitor the detection service, for example, by regularly querying the service status, such as querying whether there is a detection service. In the case where the detection service is monitored, it means that there is a service of the reclosing detection device and the control device performing a reclosing detection analysis on the reclosing circuit breaker, so as to enable subsequent analysis to determine whether the reclosing circuit breaker has a fault; in the case where the detection service is not monitored, it means that there is no service of the reclosing detection device and the control device performing a reclosing detection analysis on the reclosing circuit breaker. The detection service can be a service input by the operator into the control device, or it can be a detection service automatically generated by the service generator, so that the reclosing detection device and the control device can regularly perform a reclosing detection analysis on the reclosing circuit breaker.

[0069] With this arrangement, the reclosing circuit breaker can be analyzed in real time by monitoring the detection service through the control device, which reduces the need for manual intervention, reduces the risk of human operating errors, and helps to improve the efficiency of subsequent reclosing detection.

[0070] S200, obtaining detection and analysis information of the reclosing circuit breaker, wherein the detection and analysis information is used to reflect whether the reclosing detection device and the control device have performed effective reclosing detection and analysis on the reclosing circuit breaker.

[0071] It is understood that whether the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker can be determined by analyzing the validity of the time period (whether the required data is detected and analyzed within the collection time area). It is also possible to determine whether the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker by analyzing whether the data detected by the reclosing detection device is the same as the data analyzed by the control device.

[0072] For example, the reclosing detection device can detect different performance data in the reclosing circuit breaker in sequence within a first time period (e.g., 8:00-10:00, etc.). When the reclosing detection device acquires performance data, the order of detection is random. For example, within 8:00-9:00, the performance data acquired by the reclosing detection device in sequence may be A data, B data, and C data. Within 9:00-10:00, the performance data acquired by the reclosing detection device in sequence may be C data, B data, and A data. For example, A data may be any one of current value, voltage value, and reclosing operation frequency, and so on, B data and C data. In addition, in order to ensure that the detection is real-time, the retention time of the acquired performance data by the reclosing detection device may be 1 minute, 2 minutes, and 3 minutes, or 10 minutes, 20 minutes, and 30 minutes, etc., so that expired data is not used. The retention time of different performance data can be the same or different. For example, the retention time can be set according to actual needs, such as the retention time of A data can be 2 minutes, the retention time of B data can be 3 minutes, and the retention time of C data can be 2 minutes.

[0073] For example, while the reclosing detection device acquires performance data, the control device may send a detection and analysis request, which is used to analyze different performance data. For example, when the control device analyzes different performance data, it may be analyzed regularly, that is, the performance data is analyzed every other data collection time period, or one of the multiple data is analyzed. For example, the control device needs to analyze B data in data collection time period a (8:00-8:35), C data in data collection time period b, and A data in data collection time period c. For example, the order or type of the analyzed data is disordered or unknown, and A data may be analyzed first, then B data, and finally C data, or B data may be analyzed first, then A data, and finally C data. The data collection time periods are also different, for example, the length of the data collection time period a and the data collection time period b may be the same or different. The data collection time period is used to indicate how long the control device runs a detection and analysis request, and the collection time area is used to indicate the length of time the control device detection and analysis lasts. Therefore, only by performing detection and analysis in the collection time area of ​​the data collection time period can effective reclosing detection and analysis be performed on the reclosing circuit breaker.

[0074] For example, the reclosing detection device obtains performance data, and the control device runs a detection and analysis request. Only when the data that the control device needs to analyze is the same as the data obtained by the reclosing detection device, the control device can analyze the performance data obtained by the reclosing detection device, that is, the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker.

[0075] For example, Figure 2 As shown, different performance data in the reclosing circuit breaker are detected in sequence in a first time period (for example, 7:55-8:02), and the reclosing detection device obtains data a at 7:55 (retained until 7:57), data b at 7:57 (retained until 8:00), and data C at 8:00 (retained until 8:02). Different performance data in the reclosing circuit breaker are detected in sequence in a second time period (for example, 8:30-8:37), and the reclosing detection device obtains data C at 8:30 (retained until 8:32), and data C at 8:00 (retained until 8:02). :32 obtains data b (retained until 8:35), and obtains data a (retained until 8:37) at 8:35, and the control device needs to analyze data B in the data collection time period a (for example, 8:00-8:39), and the collection time area aa in the data collection time period a can analyze the data B corresponding to the performance data in the second time period. Therefore, the data that the control device needs to analyze is the same as the data obtained by the reclosing detection device, that is, the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker. For another example, the control device needs to analyze data A in the data collection time period a (for example, 8:00-8:39), and the collection time area aa in the data collection time period a cannot analyze the data A corresponding to the performance data in the first time period and the second time period. Therefore, the data that the control device needs to analyze is different from the data obtained by the reclosing detection device, that is, the reclosing detection device and the control device cannot perform effective reclosing detection and analysis on the reclosing circuit breaker.

[0076] With such a setting, by obtaining the detection and analysis information of the reclosing circuit breaker, it is possible to ensure that the reclosing detection device and the control device work together normally, avoid missed detection and false detection, and provide data support for the subsequent timely identification of problems or abnormalities that occur during the detection process, which helps to improve the subsequent detection efficiency of the reclosing.

[0077] S300, the control device performs analysis based on the detection service and the detection analysis information to obtain a detection result, wherein the detection result is used to reflect whether the reclosing circuit breaker is faulty.

[0078] It can be understood that the control device can parse the content in the detection business, including the detection target, parameter settings, etc. The detection task is started according to the content of the analyzed detection business. In the process of starting the detection task, the detection analysis information is parsed to determine whether the reclosing detection device and the control device have performed effective reclosing detection and analysis on the reclosing circuit breaker. If valid, the data of the effective reclosing detection is compared with the preset data to generate a detection result (for example, if the data of the effective reclosing detection is a voltage value, the voltage value of the effective reclosing detection is compared with the preset voltage value. If the voltage value of the effective reclosing detection is greater than the preset voltage value, it indicates an abnormality; otherwise, it indicates that there is no abnormality); otherwise, no detection result is generated. For example, the detection result may be that the voltage value of the current reclosing circuit breaker is abnormal, or the current value of the current reclosing circuit breaker is abnormal, or the reclosing operation frequency of the current reclosing circuit breaker is abnormal.

[0079] With such an arrangement, the control device analyzes the detection business and detection analysis information to obtain the detection result, which can help to quickly determine whether the reclosing circuit breaker is faulty, thereby reducing the reaction time of manual intervention and helping to improve the detection efficiency of the reclosing circuit breaker.

[0080] In a possible implementation, in step S300, before the control device performs analysis according to the detection service and the detection analysis information and obtains the detection result, the reclosing abnormality detection method of the reclosing circuit breaker further includes:

[0081] S310, according to the detection service, obtaining detection data of the reclosing circuit breaker detected by the reclosing detection device, wherein the detection data includes first moment data reflecting the moment when the reclosing detection device obtains the target performance data of the reclosing circuit breaker.

[0082] For example, the detection data includes first type data (i.e., whether the currently acquired performance data is A data, B data, or C data) corresponding to the performance data acquired by the reclosing detection device in different time periods (e.g., the first time period, the second time period), and the time corresponding to the acquisition of the performance data in different time periods (e.g., the first time period, the second time period). The first type data corresponding to the performance data acquired by the reclosing detection device in different time periods may be the same or different. For example, in the first time period, the first type data corresponding to the performance data acquired by the reclosing detection device is A data, and in the second time period, the first type data corresponding to the performance data acquired by the reclosing detection device is B data. For another example, in the first time period, the first type data corresponding to the performance data acquired by the reclosing detection device is A data, and in the second time period, the first type data corresponding to the performance data acquired by the reclosing detection device is also A data. For another example, in the first time period, the time corresponding to the acquisition of the performance data by the reclosing detection device is 7:55, and in the second time period, the time corresponding to the acquisition of the performance data by the reclosing detection device is 8:30. The detection service may be a service for detecting a reclosing circuit breaker, for example, a service for detecting the performance of a certain parameter.

[0083] It can be understood that the detection task is initiated according to the detection business to identify the specific data (i.e., detection data) detected by the reclosing detection device on the reclosing circuit breaker, for example, what kind of data the reclosing detection device currently obtains from the reclosing circuit breaker, such as voltage value, current value, reclosing operation frequency, etc. (i.e., target performance data), and the timestamp of data acquisition is recorded so that each data has a time identifier, that is, the first moment data when the reclosing detection device obtains the target performance data of the reclosing circuit breaker is recorded.

[0084] With such a configuration, based on the detection business, the detection data of the reclosing circuit breaker detection by the reclosing detection device is obtained, which can provide data support for the subsequent reclosing detection device and the control device to perform effective reclosing detection and analysis on the reclosing circuit breaker, which helps to avoid the problem of invalid analysis caused by the data required for analysis by the control device being different from the data obtained by the reclosing detection device, and thus helps to improve the subsequent detection efficiency.

[0085] S320, based on the first moment data in the detection data, the control device collects the target performance data acquired by the reclosing detection device.

[0086] For example, the first moment data included in the detection data for reflecting the moment when the reclosing detection device obtains the target performance data of the reclosing circuit breaker is 7:55, and the control device can start collecting the target performance data at 7:55. The first moment data included in the detection data for reflecting the moment when the reclosing detection device obtains the target performance data of the reclosing circuit breaker is 8:30, and the control device can start collecting the target performance data at 8:30. Therefore, it can be avoided that the control device performs invalid reclosing detection analysis when the reclosing detection device has not detected data or the detected data has expired and been deleted.

[0087] With such arrangement, the control device collects the target performance data acquired by the reclosing detection device according to the first moment data in the detection data, and can reliably acquire the required target performance data for subsequent analysis, thereby helping to improve detection efficiency.

[0088] In a possible implementation, the detection data further includes first type data for reflecting the type of target performance data of the reclosing circuit breaker acquired by the reclosing detection device. S320, according to the first moment data in the detection data, the control device collects the target performance data acquired by the reclosing detection device, including:

[0089] According to the first moment data and the first type data in the detection data, the control device collects the target performance data acquired by the reclosing detection device.

[0090] It can be understood that the first type of data may be data reflecting the type of target performance data, for example, the target performance data of the reclosing circuit breaker currently acquired by the reclosing detection device is A data, B data or C data.

[0091] For example, the data that the control device needs to analyze is A data, and in the first time period, the time corresponding to the performance data obtained by the reclosing detection device is 7:55, and the first type of data corresponding to the obtained performance data is A data, and in the second time period, the time corresponding to the performance data obtained by the reclosing detection device is 8:35, and the first type of data corresponding to the obtained performance data is A data. Then, the control device can collect the target performance data at 7:55 for subsequent analysis based on the detection data, which includes the first type of data corresponding to the performance data obtained by the reclosing detection device in different time periods (for example, the first time period and the second time period) (that is, whether the currently obtained performance data is A data, B data, or C data), and the time corresponding to the performance data obtained in different time periods (for example, the first time period and the second time period). If there is a collection failure problem between the current control device and the reclosing detection device (that is, the current data collection fails), the control device can also start collecting the target performance data at 8:35 for subsequent analysis.

[0092] For example, in a scenario where the data that the control device needs to analyze can be any one of A data, B data, and C data (i.e., the type of data that the control device needs to analyze is not limited), the control device can start collecting the target performance data at 7:55 based on the detection data, so that when starting at 7:55, any one of the A data, B data, and C data collected, for example, after collecting the A data, the control device can immediately analyze the A data. If there is a collection failure problem between the current control device and the reclosing detection device, the control device can also start collecting the target performance data at 8:35, so that when starting at 8:35, any one of the A data, B data, and C data collected, for example, after collecting the C data, the control device can immediately analyze the C data.

[0093] With such a configuration, the control device collects the target performance data obtained by the reclosing detection device based on the first moment data and the first type data in the detection data, which can flexibly adapt to changing data requirements and optimize the detection and analysis process to provide data support for subsequent rapid analysis results, thereby improving subsequent detection efficiency.

[0094] S330, when the target performance data is collected, generating first information in the detection and analysis information, wherein the first information is used to reflect that the reclosing detection device and the control device have performed effective reclosing detection and analysis on the reclosing circuit breaker.

[0095] It can be understood that the collected performance data can be compared with the data required to be analyzed by the control device. If they are the same (for example, if the performance data is A data and the data required to be analyzed by the control device is also A data, then they are the same), it means that the target performance data has been collected; otherwise, it means that the target performance data has not been collected. A generation algorithm or generation program is set to automatically generate the first information in the detection and analysis information when the target performance data is collected. The first information can inform the reclosing detection device and the control device that the reclosing detection analysis currently being performed is valid.

[0096] With such a setting, when the target performance data is collected, the first information in the detection and analysis information is generated, which can reduce human intervention and the risk of human error through automated analysis and information generation, thereby ensuring the accuracy of subsequent detection and analysis processes and helping to improve subsequent detection efficiency.

[0097] In a possible implementation, the detection data further includes second moment data reflecting the moment when the reclosing detection device obtains the target performance data of the reclosing circuit breaker, the second moment data is greater than the first moment data, and the reclosing abnormality detection method of the reclosing circuit breaker further includes:

[0098] S301, when the target performance data is not collected, the control device collects the target performance data obtained by the reclosing detection device according to the second moment data in the detection data.

[0099] For example, the first moment data may be 7:55, the second moment data may be 8:30, the detection data may include 7:55 and 8:30, the control device may start collecting the target performance data (for example, A data) at 7:55, and there may be a collection failure problem between the current control device and the reclosing detection device, that is, the target performance data is not collected, that is, when the target performance data is not collected, the reclosing detection device and the control device have not performed effective reclosing detection and analysis information on the reclosing circuit breaker, so the reclosing detection device can obtain the target performance data at 8:35, and the control device can collect the A data again at 8:35. When the target performance data is collected, the first information in the detection and analysis information is generated to inform the reclosing detection device and the control device that the current reclosing detection and analysis is valid.

[0100] With such arrangement, when the target performance data is not collected, the control device collects the target performance data obtained by the reclosing detection device according to the second moment data in the detection data, and can flexibly adapt to changes in the scene to ensure that the subsequent reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker, and in addition, if the data cannot be successfully collected due to various reasons (such as the operator changing the data requirements) during the first attempt, the second attempt can remedy the situation and avoid interruption of the detection activity, thereby improving the fault tolerance capability during the detection process.

[0101] S302, when the target performance data is collected according to the second moment data, the first information in the detection and analysis information is generated.

[0102] It can be understood that the performance data collected from the second moment data can be compared with the data required to be analyzed by the control device. If they are the same, it means that the target performance data has been collected; otherwise, it means that the target performance data has not been collected. A generation algorithm or generation program is set to generate the first information in the detection and analysis information when the target performance data is collected according to the second moment data. The first information can inform the reclosing detection device and the control device that the reclosing detection and analysis currently being performed is effective.

[0103] With such a configuration, when the target performance data is collected based on the data at the second moment, the first information in the detection and analysis information is generated, so that it can be understood whether the reclosing detection device and the control device perform effective reclosing detection and analysis on the reclosing circuit breaker to cope with different scenarios and avoid invalid detection.

[0104] In a possible implementation, the detection data further includes second time data for reflecting the time when the reclosing detection device obtains the target performance data of the reclosing circuit breaker, and second type data for reflecting the type of the target performance data of the reclosing circuit breaker obtained by the reclosing detection device, the second time data is greater than the first time data, and the reclosing abnormality detection method of the reclosing circuit breaker further includes:

[0105] S303: When the target performance data is not collected, the control device collects the target performance data acquired by the reclosing detection device according to the second moment data and the second type data in the detection data.

[0106] For example, Figure 2As shown, different performance data in the reclosing circuit breaker are detected in sequence in a first time period (for example, 7:55-8:02), and the reclosing detection device obtains data a at 7:55 (retained to 7:57), data b at 7:57 (retained to 8:00), and data C at 8:00 (retained to 8:02), and the first moment data is in the first time period; different performance data in the reclosing circuit breaker are detected in sequence in a second time period (for example, 8:30-8:37), and the reclosing detection device obtains data C at 8:30 (retained to 8:32), data b at 8:32 (retained to 8:35), and data a at 8:35 (retained to 8:37), and the second moment data is in the second time period.

[0107] For example, the first moment data may be 7:57, the second moment data may be 8:32, the detection data may include 7:57 and 8:32, the control device may start collecting the target performance data (for example, B data) at 7:57, but the target performance data cannot be collected at the beginning of 7:57 (that is, A data cannot be collected) because the operator changes the data to be analyzed (for example, the control device starts to analyze B data, so it starts to collect B data at 7:57, and when the collection starts, the operator changes the data to be analyzed from B data to A data, and A data is obtained at 7:55 and destroyed or deleted at 7:57), so the reclosing detection device can obtain the target performance data (that is, obtain A data) at 8:35, and the control device can collect A data again at 8:35.

[0108] For example, the first moment data may be 7:55, the second moment data may be 8:30, the detection data may include 7:55 and 8:30, the control device may start collecting the target performance data (for example, A data) at 7:55, and there may be a collection failure problem between the current control device and the reclosing detection device, so the reclosing detection device may obtain the target performance data (that is, obtain A data) at 8:35, and the control device may collect A data again at 8:35.

[0109] With such arrangement, when the target performance data is not collected, the control device collects the target performance data obtained by the reclosing detection device based on the second moment data and the second type data in the detection data, and can be flexibly adjusted according to the actual situation, thereby avoiding the problem of false detection caused by failure to effectively analyze the real-time data in time, and thus helping to provide data support for subsequent accurate data analysis.

[0110] S304: When target performance data is collected according to the second moment data and the second type data in the detection data, first information in the detection analysis information is generated.

[0111] It is understandable that Figure 3 As shown, the second type of data collected from the second moment data can be compared with the data required for analysis by the control device. If they are the same, it means that the target performance data has been collected; otherwise, it means that the target performance data has not been collected. A generation algorithm or generation program is set to generate the first information in the detection and analysis information when the target performance data is collected according to the second moment data and the second type of data in the detection data. The first information can inform the reclosing detection device and the control device that the reclosing detection analysis currently being performed is effective.

[0112] With such a setting, when the target performance data is collected based on the second moment data and the second type data in the detection data, the first information in the detection and analysis information is generated, which can maximize the use of the collected performance data and help to conduct further analysis only when the data is valid during the detection and analysis process, thereby helping to improve the accuracy of the detection results.

[0113] In a possible implementation, S320, based on the first moment data in the detection data, the control device collects the target performance data acquired by the reclosing detection device, including:

[0114] S321, determining a first collection time zone according to the first moment data, wherein the first moment data is used to reflect the moment data of the start of collection in the data collection time period, the data collection time period includes multiple collection time zones, and the first collection time zone is a collection time zone in the data collection time period.

[0115] It can be understood that the first collection time zone can be a time period for data collection, which can include a start time and an end time. The first moment data can be compared with the defined first collection time zone to determine the first collection time zone within which the first moment data falls. The first moment data can also be defined as the start time of the first collection time zone, and the retention time of the performance data corresponding to the first moment data can be defined as the end time.

[0116] For example, the first moment data may be T, the data collection time period is [T0, T1], and several collection time areas are defined, such as area 1: [T0, T0+ΔT], area 2: [T0+ΔT, T1+2ΔT]...area n: [T0+(n-1)ΔT, T1], and T is compared with each collection time area one by one. If T0≤T1<T0+ΔT, it means that area 1 is the first collection time area; if T0+ΔT≤T1<T1+2ΔT, it means that area 2 is the first collection time area.

[0117] For example, the first moment data may be T, and the retention time of the a data corresponding to the first moment data is 2 minutes, so the first collection time range may be [T, T+2 minutes].

[0118] In this way, the first collection time zone is determined based on the data at the first moment, which can provide data support for the subsequent accurate determination of which specific collection time zone the current data belongs to, thereby helping to improve the accuracy of subsequent detection and analysis.

[0119] S322, the control device collects the target performance data obtained by the reclosing detection device in the first collection time zone.

[0120] It can be understood that the specific time area of ​​the first collection time area can be analyzed, such as [T0, T0+ΔT], and the collection rules can be configured in the control device to collect the target performance data obtained by the reclosing detection device within the first collection time area. This can be achieved by programming or setting a time trigger.

[0121] With such arrangement, the control device collects the target performance data acquired by the reclosing detection device in the first collection time zone, and can reliably acquire the required target performance data for subsequent analysis, thereby helping to improve detection efficiency.

[0122] In a possible implementation, the method for detecting abnormal reclosing of a reclosing circuit breaker further includes:

[0123] S400, monitoring whether a sub-detection device is provided during the detection period. The priority of the sub-detection device operation control device and the sub-detection device to perform reclosing detection and analysis on the reclosing circuit breaker is greater than the priority of the reclosing detection device operation control device and the reclosing detection device to perform reclosing detection and analysis on the reclosing circuit breaker. During the detection period, the reclosing detection device and the control device perform reclosing detection and analysis on the reclosing circuit breaker.

[0124] It can be understood that the detection period can be the period during which the reclosing detection device and the control device perform reclosing detection and analysis on the reclosing circuit breaker, for example, a period of 20 minutes, a period of 30 minutes, a period of 40 minutes, etc. The sub-detection device can be a current detection device (such as a digital ammeter), a voltage detection device (such as a digital voltmeter), a frequency detection device (such as a frequency meter or a frequency analyzer), etc. The sub-detection device can be the same as the reclosing detection device or different. A real-time monitoring system can be built to continuously monitor whether a sub-detection device is installed during the detection period, for example, whether the sub-detection device is running.

[0125] For example, the detection accuracy of the sub-detection device is higher than that of the reclosing detection device, or the detection speed of the sub-detection device is faster than that of the reclosing detection device. Then, when it is monitored that a sub-detection device is set during the detection period, the priority of the detection activity is automatically adjusted to ensure that the control device and the sub-detection device give priority to the reclosing detection and analysis activities of the reclosing circuit breaker.

[0126] Such a configuration can provide data support for dynamically adjusting the use of detection resources according to real-time conditions in the subsequent detection by monitoring whether a sub-detection device is set up during the detection period, which helps to improve the flexibility of the detection operation.

[0127] In a possible implementation, S400, monitoring whether a sub-detection device is provided during the detection period, includes:

[0128] S410, if the reclosing detection device and the control device perform reclosing detection analysis on the reclosing circuit breaker, and other detection devices are detected during the detection period of the reclosing detection device, a data list is obtained, wherein the data list stores a list of data required for at least one performance test of the reclosing circuit breaker.

[0129] It can be understood that the data list can be a list of data required for performance detection of the reclosing circuit breaker, for example, a list of data such as current, voltage, frequency, time, power, etc. Other detection devices can be devices for detecting the reclosing circuit breaker. The data list can be set by the operator, and then the data list can be obtained by querying the record.

[0130] For example, if the reclosing detection device and the control device perform reclosing detection and analysis on the reclosing circuit breaker, and other detection devices are detected during the detection period of the reclosing detection device, it means that there may be activities with faster detection speed or higher detection accuracy than the current reclosing detection and analysis activity of the reclosing circuit breaker performed by the reclosing detection device and the control device, so it is necessary to obtain a data list to determine

[0131] With such arrangement, if the reclosing detection device and the control device perform reclosing detection analysis on the reclosing circuit breaker, and if other detection devices are detected during the detection period of the reclosing detection device, a data list can be obtained to decide whether to enable the sub-detection device, thereby avoiding waste of resources and helping to improve the efficiency of subsequent detections.

[0132] S420, obtaining whether the data of reclosing detection and analysis of the reclosing circuit breaker is stored in the data list.

[0133] It can be understood that it is possible to set which specific data or attributes need to be found in the data list, and the standards can be set according to the specific detection items, such as detection type (reclosing detection), detection time range, data items (such as current, voltage, etc.), etc. Use the written search function to run the search. If the result is returned, it means that the data for reclosing detection analysis of the reclosing circuit breaker is stored in the data list; otherwise, it means that the data for reclosing detection analysis of the reclosing circuit breaker is not stored in the data list.

[0134] In this way, by obtaining whether the data of reclosing detection and analysis of the reclosing circuit breaker is stored in the data list, manual intervention can be reduced, thereby saving time and reducing human errors.

[0135] S430, when the data acquired for the reclosing detection and analysis of the reclosing circuit breaker is stored in the data list, monitoring whether a sub-detection device is provided during the detection period of the reclosing detection device.

[0136] For example, the data used by the reclosing detection device to perform reclosing detection and analysis on the reclosing circuit breaker is A data, and the A data is stored in the data list, indicating that there are other devices that detect A data faster than the reclosing detection device or detect A data with higher accuracy than the reclosing detection device. Therefore, it is monitored whether a sub-detection device is set during the detection period of the reclosing detection device. If so, it means that a better device can be used for detection and analysis activities; if not, it means that a better device cannot be used for detection and analysis activities at present.

[0137] For example, it can be analyzed whether the priority of the currently running detection and analysis activity x needs to be used as the basis for detecting the existence of the sub-detection device. For example, if the detection speed of the current sub-detection device running the detection and analysis activity x is fast, then the priority of the detection and analysis activity x can be used as the basis for detecting the existence of the sub-detection device. For another example, if the detection speed of the current sub-detection device running the detection and analysis activity x is the same as the detection speed of the reclosing detection device running the detection and analysis activity x, then the priority of the detection and analysis activity x does not need to be used as the basis for detecting the existence of the sub-detection device.

[0138] For example, if the reclosing detection device and the control device perform reclosing detection analysis on the reclosing circuit breaker, and other detection devices are detected during the detection period of the reclosing detection device, it means that the priority of the running detection and analysis activity needs to be used as the basis for detecting the existence of the sub-detection device.

[0139] With such a configuration, when the data obtained for the reclosing detection and analysis of the reclosing circuit breaker is stored in the data list, whether a sub-detection device is set during the detection period of the monitoring reclosing detection device can be reasonably allocated according to the actual situation, thereby avoiding waste of resources and helping to improve the efficiency of subsequent detections.

[0140] S500, when it is detected that a sub-detection device is provided during the detection period, the reclosing detection device and the control device do not perform reclosing detection analysis on the reclosing circuit breaker, and send a control instruction to the sub-detection device. The control instruction is used to instruct the sub-detection device and the control device to perform reclosing detection analysis on the reclosing circuit breaker.

[0141] It can be understood that when it is detected that a sub-detection device is provided (i.e., it is in an active state), a flag can be automatically set to indicate that the activity of the reclosing detection device and the control device performing reclosing detection and analysis on the reclosing circuit breaker is not currently executed, and the activity of the sub-detection device and the control device performing reclosing detection and analysis on the reclosing circuit breaker is executed (i.e., a control instruction is sent to the sub-detection device). If it is detected that no sub-detection device is provided, it indicates that the current activity of the reclosing detection device and the control device performing reclosing detection and analysis on the reclosing circuit breaker is allowed to continue.

[0142] With such an arrangement, when it is monitored that a sub-detection device is installed during the detection period, the reclosing detection device and the control device do not perform reclosing detection analysis on the reclosing circuit breaker, and do not send control instructions to the sub-detection device. This helps to quickly respond to changes in detection conditions, reduce manual intervention, and thus reduce the risk of manual misoperation, which helps to ensure the stability of subsequent detection processes.

[0143] In a possible implementation, a method for detecting abnormal reclosing of a reclosing circuit breaker includes:

[0144] When the feedback signal from the sub-detection device is obtained, the reclosing detection device and the control device perform reclosing detection and analysis on the reclosing circuit breaker, wherein the feedback signal is used to indicate that the sub-detection device and the control device do not continue to perform reclosing detection and analysis on the reclosing circuit breaker.

[0145] It can be understood that the feedback signal can be a digital signal, an analog signal or any other form of information. The triggering condition of the feedback signal fed back by the sub-detection device to the control device can be that the sub-detection device and the control device have completed the reclosing detection analysis of the reclosing circuit breaker (that is, there is no need to continue to perform the reclosing detection analysis of the reclosing circuit breaker by the sub-detection device and the control device, that is, the subsequent use of the reclosing detection device can also achieve the same detection effect as the sub-detection device, for example, the sub-detection device may only have a better detection speed or detection accuracy of A data than the reclosing detection device, and the detection speed or detection accuracy of A data is the same as the reclosing detection device, but the energy consumption of the sub-detection device is higher than that of the reclosing detection device), or the operator interrupts the sub-detection device and the control device's reclosing detection analysis of the reclosing circuit breaker (for example, the operator finds that the sub-detection device is in a fault state), etc. When a feedback signal from the sub-detection device is obtained, it indicates that there is no need to continue to execute the sub-detection device and the control device's reclosing detection analysis on the reclosing circuit breaker, so the reclosing detection device and the control device perform reclosing detection analysis on the reclosing circuit breaker. In this way, even if the operator interrupts the reclosing detection analysis of the reclosing circuit breaker by the sub-detection device and the control device, the reclosing detection device and the control device can still perform reclosing detection analysis on the reclosing circuit breaker. Alternatively, it can avoid the problem of waste of resources caused by the sub-detection device and the control device still performing reclosing detection analysis on the reclosing circuit breaker when there is no need to continue to execute the sub-detection device and the control device's reclosing detection analysis on the reclosing circuit breaker.

[0146] With such an arrangement, when the feedback signal from the sub-detection device is obtained, the reclosing detection device and the control device perform reclosing detection analysis on the reclosing circuit breaker, and can dynamically adjust the detection strategy to flexibly respond to different detection requirements and changes in conditions to achieve better detection effects.

[0147] In a possible implementation, at S300, the control device performs analysis according to the detection service and the detection analysis information to obtain a detection result, including:

[0148] S600: In response to the detection service, after the detection analysis information is reflected as the first information, generating detection analysis data.

[0149] It can be understood that after responding to the detection service and the detection analysis information is reflected as the first information, it means that the current reclosing detection device and the control device perform effective reclosing detection analysis on the reclosing circuit breaker. Therefore, the data in the effective reclosing detection analysis process can be generated as detection analysis data, such as Figure 4 As shown, the detection and analysis data may be data reflecting the specific performance of the current reclosing circuit breaker, for example, current data, voltage data, and reclosing operation frequency data.

[0150] With such a configuration, in response to the detection service, after the detection and analysis information is reflected as the first information, detection and analysis data is generated, which can avoid the problem of false detection caused by the generation of invalid data in the reclosing detection and analysis process as detection and analysis data, thereby providing data support for the subsequent process of generating detection results.

[0151] S700: When the detection analysis data is greater than or equal to the threshold, generate a first result in the detection result, wherein the first result is used to reflect that the reclosing circuit breaker is faulty.

[0152] It is understood that a threshold value can be set to determine whether the detection and analysis data exceeds the normal range. An automatic generation program is set to automatically generate the first result in the detection result when the detection and analysis data is greater than or equal to the threshold value. For example, the current threshold value is set to 100A, and if the current value reaches or exceeds 100A, it is marked as abnormal.

[0153] With such a setting, when the detection analysis data is greater than or equal to the threshold, the first result in the detection result is generated, which can reduce the possibility of subjective judgment in the manual analysis process and contribute to the objectivity and accuracy of fault judgment.

[0154] S800: When the detection analysis data is less than the threshold, generate a second result in the detection result, wherein the second result is used to reflect that the reclosing circuit breaker has no fault.

[0155] It is understandable that a threshold value can be set to determine whether the detection and analysis data exceeds the normal range. An automatic generation program is set to automatically generate a second result in the detection result when the detection and analysis data is less than. For example, the current threshold value is set to 100A. If the current value is less than 100A, it is marked as no abnormality.

[0156] With such a configuration, when the detection analysis data is less than the threshold, a second result in the detection result is generated, which can reduce the possibility of subjective judgment in the manual analysis process and contribute to the objectivity and accuracy of fault judgment.

[0157] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0158] Corresponding to the method for detecting reclosing abnormality of a reclosing circuit breaker described in the above embodiment, an embodiment of the present application further provides a system for detecting reclosing abnormality of a reclosing circuit breaker, and each unit of the system can implement each step of the method for detecting reclosing abnormality of a reclosing circuit breaker. Figure 5A structural block diagram of a reclosing anomaly detection system for a reclosing circuit breaker provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.

[0159] Reference Figure 5 , the reclosing abnormality detection system of the reclosing circuit breaker includes:

[0160] The monitoring unit is used for the control device to monitor the detection service. The detection service is used to instruct the reclosing detection device and the control device to perform reclosing detection analysis on the reclosing circuit breaker.

[0161] The acquisition unit is used to acquire the detection and analysis information of the reclosing circuit breaker, wherein the detection and analysis information is used to reflect whether the reclosing detection device and the control device have performed effective reclosing detection and analysis on the reclosing circuit breaker.

[0162] The analysis unit is used to control the device to analyze the detection service and the detection analysis information to obtain the detection result, wherein the detection result is used to reflect whether the reclosing circuit breaker is faulty.

[0165] The present application also provides a reclosing abnormality detection device, Figure 6 This is a schematic diagram of the structure of a reclosing abnormality detection device provided in one embodiment of the present application. Figure 6 As shown, the reclosing abnormality detection device 6 of this embodiment includes: at least one processor 60 ( Figure 6 Only one is shown), at least one memory 61 ( Figure 6Only one is shown in the figure) and a computer program 62 stored in the at least one memory 61 and executable on the at least one processor 60. When the processor 60 executes the computer program 62, the reclosing abnormality detection device 6 implements the steps in the above-mentioned embodiment of the reclosing abnormality detection method for any of the reclosing circuit breakers, or the reclosing abnormality detection device 6 implements the functions of each unit in the above-mentioned system embodiments.

The frequency detection device is used to detect the reclosing operation frequency of the reclosing switch. For example, the control device can identify the short circuit condition of the reclosing switch based on the current value. The control device can also identify abnormal fluctuations or instability of the reclosing switch based on the voltage value. The control device can also analyze whether the reclosing operation of the reclosing switch is too frequent based on the reclosing operation frequency of the reclosing switch.
