Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to a generator enclosed busbar sealing detection system. Background Technology

[0002] In power systems, enclosed busbars (or closed busbars) are busbar systems consisting of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulation materials, and related accessories. Enclosed busbars include phase-separated enclosed busbars, common-enclosure (including phase-separated and common-phase) enclosed busbars, and cable busbars, widely used in power plants, substations, and industrial and residential power supply lines. During operation, enclosed busbars are frequently affected by factors such as generator vibration, temperature differences between the inside and outside of the busbar, foundation displacement, and sealant aging. These factors can damage the original sealing structure of the enclosed busbar, allowing free airflow and exchange between the inside and outside of the busbar. This enables dust, impurities, charged particles, and water mist from the outside air to penetrate and contaminate the interior of the busbar.

[0003] Currently, existing enclosed busbar systems typically incorporate drying or temperature control devices to ensure airtightness. These devices dehumidify or regulate temperature when set humidity or temperature conditions are triggered, ensuring the busbar operates in a sealed environment. However, during dehumidification and temperature control, the enclosure of the busbar cannot be guaranteed to remain completely sealed. Leaks may occur due to changes in humidity or temperature, leading to internal contamination of the busbar. Summary of the Invention

[0004] In view of this, the present invention provides a generator enclosed bus seal detection system, the main purpose of which is to solve the problem of inaccurate detection of existing generator enclosed bus seals.

[0008] The environmental information of the generator set and the basic power generation data of the generator set are collected according to the preset sampling time length. The environmental information includes ambient temperature and ambient humidity.

[0009] Based on the power generation data, the temperature change curve and the humidity change curve are corrected, and the corrected temperature change curve and humidity change curve are compared with the ambient temperature and the ambient humidity.

[0010] If the difference between the humidity change curve, the temperature change curve and the ambient humidity and the ambient temperature does not conform to the updated loss extreme value range, then it is determined that there is a leak in the enclosed busbar equipment.

[0011] According to another aspect of the present invention, a generator enclosed busbar sealing detection device is provided, comprising:

[0012] The recording module is used to record the measured humidity and temperature collected from the enclosed busbar equipment installed in the generator set;

[0014] The data acquisition module is used to collect environmental information of the generator set and basic power generation data of the generator set according to a preset sampling time length. The environmental information includes ambient temperature and ambient humidity.

[0015] The correction module is used to correct the temperature change curve and the humidity change curve based on the power generation basic data, and compare the corrected temperature change curve and humidity change curve with the ambient temperature and the ambient humidity.

[0016] The determination module is used to determine that there is a leak in the enclosed busbar equipment if the difference between the humidity change curve, the temperature change curve and the ambient humidity and the ambient temperature does not conform to the updated loss extreme value range.

[0021] This invention provides a generator enclosed busbar sealing detection system. Compared with existing technologies, this invention records measured humidity and temperature data collected from the enclosed busbar equipment installed in the generator set; generates temperature change curves corresponding to the measured temperature and humidity change curves corresponding to the measured humidity at a first preset time interval; collects environmental information of the generator set and basic power generation data of the generator set according to a preset sampling time length, the environmental information including ambient temperature and ambient humidity; corrects the temperature change curves and humidity change curves based on the basic power generation data, and compares the corrected temperature change curves and humidity change curves with the ambient temperature and ambient humidity; if the difference between the humidity change curve, temperature change curve and ambient humidity and ambient temperature does not conform to the updated loss extreme value range, it is determined that there is a leak in the enclosed busbar equipment. This system realizes the estimation of whether the enclosed busbar equipment is leaking based on ambient temperature and ambient humidity, greatly avoiding the error of determining whether there is a leak based solely on the internal detection of the equipment, improving the effectiveness of leak detection of enclosed busbar equipment, reducing the possibility of internal contamination, and thus improving the internal safety of the enclosed busbar equipment.

[0030] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0031] To ensure airtightness, existing enclosed busbar systems typically incorporate drying or temperature control devices. These devices dehumidify or control the temperature when a set humidity or temperature is triggered, ensuring the busbar operates in a sealed environment. However, during dehumidification and temperature control, the interior of the busbar casing cannot be guaranteed to remain completely sealed. Leaks may occur due to changes in humidity or temperature, leading to internal contamination. This invention provides a method for detecting the airtightness of a generator enclosed busbar. Figure 1 As shown, the method includes:

[0032] 101. Record the measured humidity and temperature collected from the enclosed busbar equipment installed in the generator set.

[0033] In this embodiment of the invention, the current execution terminal is a server that connects to the enclosed busbar equipment installed on each cable pole in the generator set to perform data processing, such as... Figure 2 As shown, each enclosed busbar device is also equipped with a humidity sensor for collecting humidity and a temperature sensor for collecting temperature. The humidity sensor and temperature sensor transmit the collected humidity and temperature measurements to the current server so that the current server can record them.

[0034] It should be noted that, while recording the measured temperature and humidity, the current server stores the measured temperature and humidity data collected from different time points and different enclosed busbar devices in order to generate the change curve in step 102.

[0035] 102. Generate the temperature change curve corresponding to the measured temperature and the humidity change curve corresponding to the measured humidity according to the first preset time interval.

[0036] In this embodiment of the invention, the server pre-configures a time interval for leak detection, using data changes within this time interval as the basis for leak detection. The first preset time interval can be 1 week, 5 days, etc., and this embodiment does not impose a specific limitation. When generating the temperature change curve corresponding to the measured temperature according to the first preset time interval, it is plotted with time on the horizontal axis and temperature value on the vertical axis. Similarly, when generating the temperature change curve corresponding to the measured humidity according to the first preset time interval, it is plotted with time on the horizontal axis and humidity value on the vertical axis, and this embodiment does not impose a specific limitation.

[0037] 103. Collect environmental information of the generator set and basic power generation data of the generator set according to the preset sampling time length.

[0038] In this embodiment of the invention, to determine whether a leak exists by comparing the environment of the generator set with the enclosed environment of the enclosed busbar equipment, the current server collects environmental information of the generator set and basic power generation information of the generator set according to a preset sampling time length for analysis and judgment. The preset sampling time length is less than a first preset time interval, so that corresponding data can be found in the change curve based on the collected environmental information and basic power generation data. The environmental information includes ambient temperature and ambient humidity, which can be real-time air temperature and humidity at the sampling time point, collected through real-time weather forecasts, etc., and this embodiment of the invention does not impose specific limitations.

[0039] It should be noted that since the enclosed busbar equipment of the generator set is a busbar system composed of a metal plate (steel plate or aluminum plate) as a protective shell, conductive busbars, insulating materials and related accessories, in order to transmit electrical energy through the busbar, when the generator set is generating electricity, electrical energy will flow through the enclosed busbar equipment for transmission. At this time, the basic data of power generation are the voltage, current and power generation time flowing through this enclosed busbar equipment, so as to determine whether there is a leak based on the temperature generated in the enclosed busbar equipment based on the basic data of power generation.

[0040] 104. Based on the power generation data, correct the temperature change curve and the humidity change curve, and compare the corrected temperature change curve and humidity change curve with the ambient temperature and the ambient humidity.

[0041] In this embodiment of the invention, since the power generation basic data will also cause the enclosed bus equipment to generate a certain temperature and reduce some humidity, in order to accurately determine whether there is a leak based on the obtained temperature change curve and humidity change curve, the temperature change curve and humidity change curve are corrected based on the power generation basic data, and the corrected temperature change curve and humidity change curve are compared with the ambient temperature and ambient humidity.

[0042] It should be noted that, in the embodiments of the present invention, during the comparison of the corrected temperature change curve and humidity change curve with the ambient temperature and ambient humidity, the comparison is specifically made with the ambient temperature at the sampling time point corresponding to the preset sampling time length on the temperature change curve, and with the humidity value at the sampling time point corresponding to the preset sampling time length on the humidity change curve, that is, the difference is calculated.

[0043] 105. If the difference between the humidity change curve, the temperature change curve and the ambient humidity and the ambient temperature does not conform to the updated loss extreme value range, then it is determined that there is a leak in the enclosed busbar equipment.

[0044] In this embodiment of the invention, after comparing the differences between the ambient humidity and ambient temperature with the humidity change curve and temperature change curve, respectively, the difference is matched with the loss extreme value range. If the difference does not match the loss extreme value range updated in the current server, it indicates that the loss between the temperature and humidity in the enclosed bus equipment and the ambient temperature and humidity is abnormal. The loss at this time may include the loss due to equipment aging, the loss due to heat conduction of the casing, etc., thereby determining that there is a leakage in the enclosed bus equipment.

[0045] It should be noted that the loss extreme value range in the embodiments of the present invention is updated over time. Therefore, the current server compares the latest loss extreme value range with the difference to meet the accuracy requirements of leakage detection.

[0046] In another embodiment of the invention, for further explanation and limitation, such as Figure 3 As shown, the step of correcting the temperature change curve and the humidity change curve based on the power generation baseline data includes:

[0047] 201. Calculate the extreme temperature and extreme humidity values ​​corresponding to the power generation basic data in each of the enclosed busbar devices according to the peak values ​​of the temperature change curve and the humidity change curve;

[0048] 202a. If the number of intersections between the temperature change curve and the temperature extreme value is greater than the preset first number of intersections, then the average value of the temperature curve peak value is calculated according to the temperature extreme value, and the calculated average value is determined as the corrected temperature curve peak value in the temperature change curve.

[0049] 202b. If the number of intersections between the humidity change curve and the humidity extreme value is greater than the preset second number of intersections, then the average value of the humidity curve peak value is calculated according to the humidity extreme value, and the calculated average value is determined as the corrected humidity curve peak value in the humidity change curve.

[0050] To correct temperature and humidity variation curves based on power generation baseline data, thereby improving the effectiveness of correction for temperature and humidity changes when the enclosed busbar equipment is energized, the correction process first identifies the peak values ​​of the generated temperature and humidity variation curves—that is, the maximum and minimum values ​​of the curve fluctuations. Then, the extreme temperatures and humidity values ​​corresponding to the power generation baseline data are calculated based on these peak values. Specifically, when calculating the extreme temperatures based on the peak values, which include both maximum and minimum temperatures, the heat generated is calculated from the current in the power generation baseline data. This calculated heat is then converted to temperature and multiplied by the maximum and minimum temperature values ​​from the curve peaks using a weighted multiplication formula, such as: Where 'a' is the multiplication weight, 't1' is the temperature converted from the power generation basic data, and 't2' represents the maximum and minimum temperature values, respectively. When 'a' corresponds to the maximum value, it is preferably 0.8; when 'a' corresponds to the minimum value, it is preferably 0.2. This allows the calculation of the maximum and minimum temperature values ​​corresponding to the power generation basic data. Furthermore, in this embodiment of the invention, when calculating the humidity extreme value based on the power generation basic data, only the correspondence between the voltage in the power generation basic data and the humidity-pressure relationship pre-marked on the encapsulation bus equipment is calculated. For example, the pressure range ab corresponds to the humidity extreme value xy, thus calculating the humidity extreme value.

[0051] It should be noted that after calculating the extreme values ​​of temperature and humidity, the extreme values ​​of temperature and humidity are compared and aligned on the temperature change curve and humidity change curve, respectively. In this case, the curves with temperature as the vertical axis can show whether the extreme values ​​of temperature intersect with the temperature change curve, and vice versa. If the number of intersection points between the temperature change curve and the extreme values ​​of temperature is greater than the preset first number of intersection points, it indicates that an abnormal temperature situation occurs during the temperature change process that does not meet the preset conditions. The temperature correction condition is set by the number of intersection points. The average value of the peak value of the temperature curve is calculated based on the extreme values ​​of temperature, and this average value is determined as the corrected peak value of the temperature change curve. The average value calculation involves calculating the average value between the extreme values ​​of temperature and the peak value of the temperature curve, and then using this average value as the corrected peak value of the temperature change curve. The correction of the peak value of the humidity curve is performed using the same method, which will not be elaborated further in this embodiment. Furthermore, the preset first number of intersection points and the preset second number of intersection points can be configured based on leakage requirements, such as 3 or 5, etc., and this embodiment does not impose specific limitations.

[0052] In another embodiment of the invention, for further explanation and limitation, the steps further include:

[0053] If the number of intersections between the temperature change curve and the temperature extreme value is less than or equal to the preset first number of intersections, then the target temperature curve peak is selected based on the number of adjacent peaks of the temperature curve, and the target temperature curve peak is integrated to determine the corrected temperature curve peak in the temperature change curve.

[0054] If the number of intersections between the humidity change curve and the humidity extreme value is less than or equal to the preset second number of intersections, then the target humidity curve peak is selected based on the number of adjacent peaks of the humidity curve, and the target humidity curve peak is integrated to determine the corrected humidity curve peak in the humidity change curve.

[0055] To meet the correction requirements, another correction method in this embodiment of the invention is that the number of intersections between the temperature change curve and the temperature extreme value is less than or equal to a preset first number of intersections. In this case, it indicates that the temperature or humidity values ​​that need to be corrected are not numerous. Therefore, based on the number of adjacent peaks of the temperature curve, target temperature curve peaks are first selected, and these target temperature curve peaks are integrated to determine the corrected temperature curve peak in the temperature change curve. For example, if temperature curve peak a has two consecutive adjacent temperature curve peaks b and c, temperature curve peaks a, b, and c are selected as target temperature curve peaks. These three temperature curve peaks are then integrated, i.e., an average value is calculated, to obtain an integrated temperature curve peak, which is used as the corrected temperature curve peak. Preferably, the number of adjacent peaks is three, thus integrating the average value of the four temperature curve peaks as the corrected temperature curve peak. The correction method for the humidity curve peak is the same, and will not be elaborated further in this embodiment of the invention.

[0056] In another embodiment of the invention, for further explanation and limitation, before comparing the corrected temperature change curve and humidity change curve with the ambient temperature and ambient humidity, the method further includes:

[0057] The equipment loss data of the enclosed busbar equipment is obtained according to the second preset time interval.

[0058] The equipment loss data and the power generation baseline data are evaluated and predicted based on the loss assessment model that has been trained, and the loss extreme value range is obtained and determined as the updated loss extreme value range.

[0059] Because the enclosed busbar equipment is exposed to the outdoor environment for extended periods, a loss value range needs to be determined based on the equipment's wear and tear before calibration. The difference between the measured values ​​is then used to determine if the loss falls within the latest range. Specifically, the server acquires equipment wear data for the enclosed busbar equipment at a second preset time interval. This data includes the equipment's usage time, maximum maintenance duration, number of repairs, and number of leaks. Based on a pre-trained loss assessment model, the server evaluates and predicts the equipment wear data and basic power generation data to determine the extreme loss range. During the training of the loss assessment model, the model can be a machine learning algorithm such as a convolutional neural network, deep learning model, or support vector machine model, trained using constructed training samples. These training samples include historical equipment wear data and historical basic power generation data with marked extreme loss values. These marked extreme loss data and historical basic power generation data can be manually labeled or labeled using a pre-configured labeling algorithm; this embodiment of the invention does not impose specific limitations. Meanwhile, the marked loss extreme value can be configured according to the leakage loss of the enclosed busbar equipment during the inspection by the technicians, and the embodiments of the present invention do not make specific limitations.

[0060] In another embodiment of the invention, for further explanation and limitation, such as Figure 4 As shown, the steps also include:

[0061] 301. Given at least ten enclosed busbar devices, determine whether there are abnormal temperatures and / or abnormal humidity in each of the enclosed busbar devices;

[0062] 302. If there is an abnormal temperature and / or abnormal humidity, obtain the adjacent temperature change curves and adjacent humidity change curves of the adjacent enclosed busbar equipment of the target abnormal enclosed busbar equipment.

[0063] 303. If the difference between the adjacent temperature change curve and the adjacent humidity change curve and the temperature change curve and humidity change curve of the target abnormal enclosed busbar equipment is greater than the preset adjacent threshold, then it is determined that the target abnormal enclosed busbar equipment has a leak.

[0064] To meet the diverse needs of leak detection in enclosed busbar equipment, in a specific implementation scenario where the number of enclosed busbars in a generator unit exceeds ten, the system first determines whether any enclosed busbars exhibit abnormal temperature or humidity. If an enclosed busbar exhibits abnormal temperature and / or humidity (i.e., a target abnormal enclosed busbar), the system acquires the adjacent temperature and humidity change curves of its neighboring enclosed busbars. This allows for the estimation of whether the target abnormal enclosed busbar is leaking based on these adjacent enclosed busbars. The other adjacent enclosed busbars can be the nearest enclosed busbars within a preset distance range, such as within 20 meters. There can be multiple adjacent enclosed busbars, or only one; this embodiment of the invention does not impose a specific limitation. When the difference between the adjacent temperature and humidity change curves of adjacent enclosed busbar equipment and the temperature and humidity change curves of the target abnormal enclosed busbar equipment exceeds a preset adjacent threshold, it indicates that there is a significant difference in temperature and humidity between adjacent enclosed busbar equipment in the same environment. This confirms that the target abnormal enclosed busbar equipment has a leak, greatly improving the effectiveness of enclosed busbar equipment leak detection. In this case, the preset adjacent threshold can be configured based on differences in environmental distance; this embodiment of the invention does not impose specific limitations.

[0065] It should be noted that if it is determined that there is no abnormal temperature and / or humidity in each of the enclosed busbar devices, the leakage detection method in 102 and 105 of the present invention can be used, and the present invention does not make specific limitations.

[0066] In another embodiment of the invention, for further explanation and limitation, the step of determining whether there is an abnormal temperature and / or humidity in each of the enclosed busbar devices includes:

[0067] Obtain the real-time temperature and humidity of all the enclosed busbar equipment;

[0068] Calculate the average temperature value of the real-time temperature, and calculate the average humidity value of the real-time humidity;

[0069] The enclosed busbar equipment whose real-time temperature is lower than the average temperature and whose difference is greater than a preset difference value is identified as a target abnormal enclosed busbar equipment with abnormal temperature, and / or the enclosed busbar equipment whose real-time humidity is greater than the average humidity and whose difference is greater than a preset difference value is identified as a target abnormal enclosed busbar equipment with abnormal humidity.

[0070] To accurately determine whether there are temperature or humidity anomalies in multiple enclosed busbar devices for leak detection, the server acquires multiple real-time temperatures and humidity values ​​for each enclosed busbar device at specific time intervals. These values ​​are collected in real-time at the sampling points. The average real-time temperature and humidity values ​​are calculated and compared. If the real-time temperature is lower than the average temperature, and the difference between the real-time temperature and the average temperature is greater than a preset difference value, it indicates that the enclosed busbar device may be experiencing temperature loss due to leakage. Therefore, the corresponding enclosed busbar device is identified as a target abnormal enclosed busbar device with temperature anomalies. Similarly, if the real-time humidity is higher than the average humidity, and the difference between the real-time humidity and the average temperature is greater than a preset difference value, it indicates that the humidity within the enclosed busbar device may be rising due to external humidity influences caused by leakage. Therefore, the corresponding enclosed busbar device is identified as a target abnormal enclosed busbar device with humidity anomalies.

[0071] In another embodiment of the invention, for further explanation and limitation, the steps further include:

[0072] Once a leak is detected in the enclosed busbar equipment, the inspection terminal associated with the enclosed busbar equipment is identified, and a leak warning instruction is sent to the inspection terminal.

[0073] In this embodiment of the invention, to ensure timely remediation of leaking enclosed busbar equipment and guarantee safety during power generation, upon determining a leak in the enclosed busbar equipment, the current server identifies the inspection terminals associated with the enclosed busbar equipment and sends a leak warning instruction. These associated inspection terminals are those bound to multiple specified enclosed busbar equipment for inspection. Based on the generator unit information and the enclosed busbar equipment identifier contained in the leak warning instruction, the leaking enclosed busbar equipment is identified, allowing inspection personnel to locate it and perform subsequent leak handling. This embodiment of the invention does not impose specific limitations on this aspect.

[0074] This invention provides a method for detecting the seal of a generator enclosed busbar. Compared with existing technologies, this invention records measured humidity and temperature data collected from the enclosed busbar equipment installed in the generator set; generates a temperature change curve corresponding to the measured temperature and a humidity change curve corresponding to the measured humidity at a first preset time interval; collects environmental information of the generator set and basic power generation data of the generator set at a preset sampling time length, the environmental information including ambient temperature and ambient humidity; corrects the temperature change curve and humidity change curve based on the basic power generation data, and compares the corrected temperature change curve and humidity change curve with the ambient temperature and ambient humidity; if the difference between the humidity change curve, temperature change curve and ambient humidity and ambient temperature does not conform to the updated loss extreme value range, it is determined that there is a leak in the enclosed busbar equipment. This method realizes the estimation of whether the enclosed busbar equipment is leaking based on ambient temperature and ambient humidity, greatly avoiding the error of determining whether there is a leak based solely on the internal detection of the equipment, improving the effectiveness of leak detection of enclosed busbar equipment, reducing the possibility of internal contamination, and thus improving the internal safety of the enclosed busbar equipment.

[0075] Furthermore, as a response to the above Figure 1 The implementation of the method shown in this invention provides a generator enclosed busbar sealing detection device, such as... Figure 5 As shown, the device includes:

[0076] Recording module 41 is used to record the measured humidity and measured temperature collected from the enclosed busbar equipment installed in the generator set;

[0077] The generation module 42 is used to generate a temperature change curve corresponding to the measured temperature and a humidity change curve corresponding to the measured humidity according to a first preset time interval.

[0078] The acquisition module 43 is used to acquire environmental information of the generator set and basic power generation data of the generator set according to a preset sampling time length. The environmental information includes ambient temperature and ambient humidity.

[0079] The correction module 44 is used to correct the temperature change curve and the humidity change curve based on the power generation basic data, and compare the corrected temperature change curve and humidity change curve with the ambient temperature and the ambient humidity.

[0080] The determination module 45 is used to determine that there is a leak in the enclosed busbar equipment if the difference between the humidity change curve, the temperature change curve and the ambient humidity and the ambient temperature does not conform to the updated loss extreme value range.

[0081] Further, the correction module is specifically used to calculate the extreme temperature and extreme humidity values ​​corresponding to the power generation basic data in each of the enclosed busbar devices according to the peak values ​​of the temperature change curve and the humidity change curve; if the number of intersections between the temperature change curve and the extreme temperature value is greater than a preset first number of intersections, then the average value of the peak value of the temperature curve is calculated according to the extreme temperature value, and the calculated average value is determined as the corrected peak value of the temperature curve in the temperature change curve; if the number of intersections between the humidity change curve and the extreme humidity value is greater than a preset second number of intersections, then the average value of the peak value of the humidity curve is calculated according to the extreme humidity value, and the calculated average value is determined as the corrected peak value of the humidity curve in the humidity change curve.

[0082] Furthermore, the correction module is also configured to: if the number of intersections between the temperature change curve and the temperature extreme value is less than or equal to a preset first number of intersections, then filter a target temperature curve peak based on the number of adjacent peaks of the temperature curve, and integrate the target temperature curve peaks to determine the corrected temperature curve peak in the temperature change curve; if the number of intersections between the humidity change curve and the humidity extreme value is less than or equal to a preset second number of intersections, then filter a target humidity curve peak based on the number of adjacent peaks of the humidity curve, and integrate the target humidity curve peaks to determine the corrected humidity curve peak in the humidity change curve.

[0083] Furthermore, the device also includes:

[0084] The acquisition module is used to acquire equipment loss data of the enclosed busbar equipment according to a second preset time interval;

[0085] The prediction module is used to evaluate and predict the equipment loss data and the power generation basic data based on the loss assessment model that has been trained, and to obtain the loss extreme value range, which is then determined as the updated loss extreme value range. The loss assessment model is obtained by training the model based on historical equipment loss data and historical power generation basic data with marked loss extreme values.

[0086] Furthermore, the device also includes: a judgment module,

[0087] The judgment module is used to determine whether there is temperature abnormality and / or humidity abnormality in each of the enclosed busbar devices, provided that there are at least ten enclosed busbar devices.

[0088] The acquisition module is also used to acquire the adjacent temperature change curves and adjacent humidity change curves of the adjacent enclosed busbars of the target abnormal enclosed busbar if there is an abnormal temperature and / or abnormal humidity.

[0089] The determining module is further configured to determine that the target abnormal enclosed busbar equipment has a leak if the difference between the adjacent temperature change curve and the adjacent humidity change curve and the temperature change curve and humidity change curve of the target abnormal enclosed busbar equipment is greater than a preset adjacent threshold.

[0090] Furthermore, the judgment module is specifically used to acquire the real-time temperature and real-time humidity of all the enclosed busbar equipment; calculate the average temperature value of the real-time temperature and the average humidity value of the real-time humidity; determine the enclosed busbar equipment whose real-time temperature is less than the average temperature and the difference is greater than a preset difference value as target abnormal enclosed busbar equipment with abnormal temperature, and / or determine the enclosed busbar equipment whose real-time humidity is greater than the average humidity and the difference is greater than a preset difference value as target abnormal enclosed busbar equipment with abnormal humidity.

[0091] Furthermore, the device also includes:

[0092] The sending module is used to determine the inspection terminal associated with the enclosed bus equipment after it is determined that there is a leak in the enclosed bus equipment, and send a leak warning instruction to the inspection terminal. The leak warning instruction contains the generator set information of the enclosed bus equipment and the identification of the enclosed bus equipment, so as to determine the location of the enclosed bus equipment for leak inspection.

[0093] This invention provides a generator enclosed busbar sealing detection device. Compared with the prior art, the embodiment of this invention records the measured humidity and temperature collected from the enclosed busbar equipment installed in the generator set; generates a temperature change curve corresponding to the measured temperature and a humidity change curve corresponding to the measured humidity according to a first preset time interval; collects environmental information of the generator set and basic power generation data of the generator set according to a preset sampling time length, the environmental information including ambient temperature and ambient humidity; corrects the temperature change curve and the humidity change curve based on the basic power generation data, and compares the corrected temperature change curve and the humidity change curve with the ambient temperature and the ambient humidity; if the difference between the humidity change curve, the temperature change curve and the ambient humidity and the ambient temperature does not conform to the updated loss extreme value range, it is determined that there is a leak in the enclosed busbar equipment.
