[0002] A high-voltage medium-mounted switch cabinet is a switchgear that uses metal armoring and places main electrical components such as circuit breakers in a middle removable position, and realizes the control, protection, monitoring and metering of high-voltage circuits through electrical components such as circuit breakers, current transformers, and relays inside it.

[0003] At present, with the continuous development of the power system, as a key device for power distribution and control, the operation stability and reliability of high-voltage medium-mounted switch cabinets are crucial. During the operation of high-voltage medium-mounted switch cabinets, the monitoring of high-voltage medium-mounted switch cabinets relies on manual inspection or instrument measurement for detection. When using instrument measurement for detection, if the detected parameters exceed the normal range, indicating that a fault has occurred in the high-voltage medium-mounted switch cabinet at this time, an alarm will be issued.

[0004] The current high-voltage medium-mounted switch cabinets mainly issue alarms after a fault occurs, and have limited ability to predict faults in advance.

[0017] By adopting the above technical solution, the foreign object detection information of the switch cabinet is obtained. When the foreign object detection information contains foreign object features, the foreign object type is determined by analyzing the foreign object detection information of the high-voltage medium-mounted switch cabinet, and the foreign object type is analyzed to determine whether it is necessary to blow or grasp the high-voltage medium-mounted switch cabinet, and the corresponding warning information is formed and sent to the terminal held by the staff member, so as to timely give an early warning of the abnormal situation of the high-voltage medium-mounted switch cabinet.

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 is a flowchart of a method for early warning of high-voltage medium-mounted switchgear according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0027] A method for early warning of high-voltage medium-mounted switchgear detects temperature, voltage, current, mechanical operation, etc. in sequence by obtaining equipment operation parameters and model information, determines corresponding early warning information according to different detection results and sends it to the staff terminal, also detects and gives an early warning for the approach of foreign objects. After inputting the corresponding early warning information, judge the situation of early warning cancellation. If it is not cancelled, decide whether to continue to alarm, cut off the power or notify other receiving ends according to the actual situation, so as to give an early warning of the abnormal situation of the high-voltage medium-mounted switchgear in a timely manner.

[0028] Referring to Figure 1 , an embodiment of the present application discloses a method for early warning of high-voltage medium-mounted switchgear, including the following steps: Step 100: Obtain the equipment operation parameter information and model information of the high-voltage medium-mounted switchgear.

[0029] The device operation parameter information refers to the real-time data during the current operation of the high-voltage medium-mounted switchgear. The device operation parameter information includes temperature detection information, voltage detection information, and current detection information. The temperature detection information is obtained through a preset temperature sensor, the voltage detection information is obtained through a preset voltage sensor, and the current detection information is obtained through a preset current sensor. The model information refers to the device model parameters of the switchgear, which are obtained through pre-input. The model information includes a reference temperature value, a reference time interval, a voltage-temperature safety interval, a reference voltage value, a reference current value, and a mechanical reference state value.

[0030] The device operation parameter information of the switchgear is obtained through temperature sensors, voltage sensors, and current sensors, and the model information is obtained through pre-input by the staff.

[0031] Step 101: Retrieve the temperature detection information, voltage detection information, and current detection information according to the device operation parameter information.

[0032] The temperature detection information refers to the detection information obtained through the temperature sensor in the high-voltage medium-mounted switchgear. The temperature detection information includes a temperature detection value and an abnormal temperature time.

[0033] The voltage detection information refers to the detection information obtained through the voltage sensor in the switchgear. The voltage detection information includes a detected voltage value. The current detection information refers to the detection information obtained through the current sensor in the switchgear. The current detection information includes a detected current value. By retrieving the temperature detection information, voltage detection information, and current detection information from the device operation parameter information, the temperature detection information, voltage detection information, and current detection information are obtained.

[0034] Step 102: Determine whether the preset temperature anomaly feature is included in the temperature detection information.

[0035] The temperature anomaly feature refers to the temperature feature corresponding to the abnormal stability in the high switchgear, which is preset by the staff. By judging whether the preset temperature anomaly feature is included in the temperature detection information, it is determined whether there is a temperature anomaly in the switchgear.

[0036] Step 1020: If the temperature anomaly feature is not included in the temperature detection information, perform the detection with a preset voltage detection method.

[0037] If the temperature anomaly feature is not included in the temperature detection information, it means that there is no temperature anomaly in the switchgear. If the detected temperature exceeds the standard temperature within a unit time, it means that it is an abnormal temperature situation, and then perform the detection with a preset voltage detection method. The voltage detection method refers to the method for detecting the voltage of the switchgear. The voltage detection method is Steps 300 - 303.

[0038] Step 1021: If the temperature detection information contains temperature anomaly features, determine the abnormal temperature position based on the temperature detection information and the temperature anomaly features.

[0039] The abnormal temperature position refers to the position where the temperature in the switch cabinet is abnormal. If the temperature detection information contains temperature anomaly features, it indicates that the temperature in the switch cabinet is abnormal. Then, analyze the position where the temperature anomaly features exist in the temperature detection information to determine the abnormal temperature position.

[0040] Step 103: Determine the reference temperature value and the reference time interval according to the model information.

[0041] The reference temperature value refers to the standard temperature value of the switch cabinet. The reference time interval refers to the time range within which the switch cabinet allows the abnormal temperature to fluctuate within a certain range. Retrieve the reference temperature value and the reference time interval through the model information, so as to obtain the reference temperature value and the reference time interval.

[0042] Step 104: Retrieve the temperature detection value and the abnormal temperature time according to the temperature detection information.

[0043] The temperature detection value refers to the temperature value detected by the temperature sensor in the switch cabinet. The abnormal temperature time refers to the duration of the abnormal temperature change in the switch cabinet. Retrieve the temperature detection value and the abnormal temperature time through the temperature detection information, so as to obtain the temperature detection value and the abnormal temperature time.

[0044] Step 105: Calculate the difference between the temperature detection value and the reference temperature value and use it as the temperature anomaly value.

[0045] The temperature anomaly value refers to the amount by which the actual temperature of the switch cabinet deviates from the normal standard. Analyze and calculate the difference between the temperature detection value and the reference temperature value, and use the difference as the temperature anomaly value.

[0046] Step 106: Determine whether the abnormal temperature time falls within the reference time interval.

[0047] The reference time interval refers to the time period during which the temperature of the switch cabinet can fluctuate. The reference time interval is preset by the staff. Determine whether the abnormal temperature will affect the switch cabinet by judging whether the abnormal temperature time falls within the reference time interval.

[0048] Step 1060: If the abnormal temperature time falls within the reference time interval, re-acquire the device operation parameter information.

[0049] If the abnormal temperature time falls within the reference time interval, it indicates that the abnormal temperature in the switch cabinet lasts for a short time and will not affect the switch cabinet. Then, re-acquire the device operation parameter information.

[0050] Step 1061: If the abnormal temperature time does not fall within the reference time interval, determine the temperature warning information based on the temperature detection information, and output the temperature warning information to the terminals held by the preset staff.

[0051] The temperature warning information refers to the message for prompting when abnormal temperature conditions occur inside the switch cabinet. The confirmation method of the temperature warning information is Steps 200 - 208. The terminals held by the staff refer to the devices specially equipped for the staff to receive various warning information and instructions sent by the switch cabinet and can perform relevant operations, such as operating and receiving through a computer. If the abnormal temperature time does not fall within the reference time interval, it indicates that the abnormal temperature inside the switch cabinet affects the switch cabinet. Then, by analyzing the temperature detection information, the temperature warning information is determined and output to the terminals held by the preset staff, so as to give an early warning of the abnormal situation of the switch cabinet in a timely manner.

[0052] In Figure 1 In Step 1061 shown above, in order to further ensure the reasonableness of the temperature warning information, it is necessary to perform a further separate analysis and calculation on the temperature warning information. The determination method of the temperature warning information includes: Step 200: Define the current detection information corresponding to the abnormal temperature position as abnormal current temperature information, and determine whether the abnormal current temperature information contains the preset poor contact characteristics.

[0053] The poor contact characteristics refer to the characteristics of potential poor contact faults at the electrical connection parts inside the switch cabinet in the current detection information, and the poor contact characteristics are set by the staff in advance.

[0054] Define the current detection information corresponding to the abnormal temperature position as abnormal current temperature information, and determine whether the abnormal temperature of the switch cabinet is caused by poor contact by determining whether the abnormal current temperature information contains the preset poor contact characteristics.

[0055] Step 2000: If the abnormal current temperature information contains the poor contact characteristics, determine the cable information according to the model information.

[0056] The cable information refers to the model parameters of the cable that needs to be replaced. If the abnormal current temperature information contains the poor contact characteristics, it indicates that there is an abnormality in the current of the switch cabinet. Then, the model information is input into the preset cable database to obtain the cable information. Different cable information corresponding to different model information is stored in the cable database, and the cable database is set by the staff in advance, which will not be elaborated here.

[0057] Step 201: Determine the replacement position according to the abnormal temperature position.

[0058] The replacement position refers to the specific position point within the switchgear cabinet where cable replacement operations need to be carried out corresponding to the abnormal temperature position. The cable position closest to the abnormal temperature position is taken as the replacement position.

[0059] Step 202: Determine the replacement warning information based on the cable information and the replacement position, and use the replacement warning information as the temperature warning information.

[0060] The replacement warning information refers to the operation guidelines and warning information for cable replacement operations required for the switchgear cabinet due to abnormal temperature and possible poor contact problems. The replacement warning information includes the model information of the cable to be replaced and the warning message.

[0061] By analyzing the cable information and the replacement position, the cable information and the replacement position are used as the replacement warning information, and the replacement warning information is used as the temperature warning information.

[0062] Step 2001: If the abnormal current temperature information does not contain the characteristic of poor contact, determine the voltage value based on the voltage detection information and the abnormal temperature position.

[0063] The voltage value refers to the voltage data corresponding to the abnormal temperature position. If the abnormal current temperature information does not contain the characteristic of poor contact, it means that the current of the switchgear cabinet is normal, and the voltage corresponding to the abnormal temperature position in the voltage detection information is retrieved to determine the voltage value.

[0064] Step 203: Determine the voltage-temperature safety range according to the model information.

[0065] The voltage-temperature safety range refers to the safety range corresponding to the voltage that does not cause abnormal temperature of the switchgear cabinet under normal operating conditions. The voltage-temperature safety range is preset by the staff. The voltage safety range is retrieved through the model information to obtain the voltage-temperature safety range.

[0066] Step 204: Determine whether the voltage value falls within the voltage-temperature safety range.

[0067] By judging whether the voltage value falls within the voltage-temperature safety range, it is determined whether abnormal temperature will be caused by the voltage.

[0068] Step 2040: If the voltage value does not fall within the voltage safety range, determine the heat dissipation value according to the voltage value.

[0069] The heat dissipation value refers to the amount of heat that needs to be dissipated by the heat dissipation system to ensure the normal operation of the equipment inside the switchgear when the voltage is too high during the operation of the switchgear. If the voltage value does not fall within the voltage safety range, it indicates that there is a problem with the voltage in the switchgear. Then, the voltage value is input into the preset heat dissipation database to obtain the heat dissipation value. The heat dissipation database stores the heat dissipation values corresponding to different voltage values, which are pre-set by the staff and will not be elaborated here.

[0070] Step 205: Determine the repair location according to the abnormal temperature location.

[0071] The repair location refers to the specific location inside the switchgear where repair operations are carried out for the heating problem caused by voltage abnormality directly corresponding to the abnormal temperature location. By analyzing the voltage fluctuation in the abnormal temperature location through the voltage detection information, the component location corresponding to the abnormal temperature location is used as the repair location.

[0072] Step 206: Determine the repair voltage information according to the heat dissipation value and the repair location, and define the repair voltage information as the temperature warning information.

[0073] The repair voltage information refers to the operation guidance and warning information generated based on the heat dissipation value and the repair location, which is provided for the staff and is targeted to solve the heating problem of the switchgear caused by voltage abnormality. The repair voltage information corresponding to different heat dissipation values and repair locations is stored in the voltage repair database, which is pre-set by the staff. The heat dissipation value and the repair location are input into the preset voltage repair database to obtain the repair voltage information, and the repair voltage information is defined as the temperature warning information.

[0074] Step 2041: If the voltage value falls within the voltage safety range, determine whether the abnormal temperature location falls within the preset ventilation and heat dissipation location range.

[0075] The ventilation and heat dissipation location range refers to the location range of the ventilation openings and heat dissipation openings of the switchgear, which is pre-set by the staff. If the voltage value falls within the voltage safety range, it indicates that the voltage of the switchgear is normal. Then, by judging whether the abnormal temperature location falls within the preset ventilation and heat dissipation location range, it is determined whether the temperature is too high due to the blockage of the ventilation openings or heat dissipation openings.

[0076] Step 20410: If the abnormal temperature location falls within the ventilation and heat dissipation location range, obtain the ventilation detection information of the high-voltage medium-mounted switchgear.

[0077] Ventilation detection information refers to the degree of foreign object coverage of the ventilation openings and heat dissipation openings of the switch cabinet. The ventilation detection information is obtained by optical sensors respectively preset at the ventilation openings and heat dissipation openings. If the abnormal temperature position falls within the ventilation and heat dissipation position range, it indicates that the temperature of the switch cabinet may be abnormal due to the blockage of the ventilation opening or heat dissipation opening.

[0078] Step 207: Determine the blockage value according to the ventilation detection information.

[0079] The blockage value refers to the degree of blockage of the ventilation opening or heat dissipation opening. By inputting the ventilation detection information into a preset blockage database, the blockage value can be obtained. Different blockage values corresponding to different ventilation detection information are stored in the blockage database, which is pre-set by the staff and will not be elaborated here.

[0080] Step 208: Determine the dust suction parameters according to the blockage value, define the dust suction parameters as dust suction warning information, and define the dust suction warning information as temperature warning information.

[0081] The dust suction parameters refer to the specific operation parameters determined for effectively cleaning the blockage of the ventilation openings and heat dissipation openings of the switch cabinet. The dust suction warning information refers to a comprehensive warning message to remind the staff to perform dust suction cleaning on the ventilation system of the switch cabinet. By inputting the blockage value into a preset dust suction database, the dust suction parameters can be obtained, and the dust suction parameters are defined as dust suction warning information, and the dust suction warning information is defined as temperature warning information. Different dust suction parameters corresponding to different blockage values are stored in the dust suction database, which is pre-set by the staff and will not be elaborated here.

[0082] Step 20411: If the abnormal temperature position does not fall within the ventilation and heat dissipation position range, re-obtain the device operation parameter information.

[0083] If the abnormal temperature position does not fall within the ventilation and heat dissipation position range, it indicates that the ventilation openings and heat dissipation openings are operating normally, then re-obtain the device operation parameter information.

[0084] In step 1020, in order to further ensure the safe operation of the switch cabinet, it is necessary to perform a further separate analysis and calculation on the voltage of the switch cabinet. The voltage detection methods include: Step 300: Determine whether the preset voltage abnormal characteristics are included in the voltage detection information.

[0085] The voltage abnormal characteristics refer to the characteristics when the voltage in the switch cabinet is abnormal, which are pre-set by the staff. By judging whether the preset voltage abnormal characteristics are included in the voltage detection information, the normality of the voltage can be determined.

[0086] Step 3000: If the voltage detection information does not contain voltage anomaly characteristics, perform detection using a preset current detection method.

[0087] If the voltage detection information does not contain voltage anomaly characteristics, it indicates that the voltage in the switch cabinet is normal, and then perform detection using a preset current detection method. The current detection method refers to the method for detecting the cable of the switch cabinet. The current detection method is Steps 400 - 404.

[0088] Step 3001: If the voltage detection information contains voltage anomaly characteristics, determine the reference voltage value according to the model information.

[0089] The reference voltage value is a standard voltage value determined according to the voltage requirement during the normal operation of the switch cabinet. If the voltage detection information contains voltage anomaly characteristics, it indicates that the voltage of the switch cabinet is abnormal, and then retrieve the reference voltage value through the model information to obtain the reference voltage value.

[0090] Step 301: Retrieve the detected voltage value according to the voltage detection information.

[0091] The detected voltage value refers to the voltage value obtained by detecting the switch cabinet. The detected voltage value is retrieved through the voltage detection information.

[0092] Step 302: Determine the voltage anomaly value according to the reference voltage value and the detected voltage value.

[0093] The voltage anomaly value refers to the value of the deviation degree between the actual detected voltage of the switch cabinet and the reference voltage. By analyzing and calculating the difference between the reference voltage value and the detected voltage value, the voltage anomaly value is obtained.

[0094] Step 303: Determine whether the voltage anomaly value falls within a preset voltage safety range.

[0095] The voltage safety range refers to the voltage range within which the voltage fluctuates within a certain range without causing obvious adverse effects on the normal operation and service life of the switch cabinet, and the voltage safety range is preset by the staff. By judging whether the voltage anomaly value falls within the preset voltage safety range, it is determined whether the switch cabinet will be affected by the voltage.

[0096] Step 3030: If the voltage anomaly value falls within the voltage safety range, re - obtain the device operation parameter information.

[0097] If the voltage anomaly value falls within the voltage safety range, it indicates that the voltage of the switch cabinet is okay, and then re - obtain the device operation parameter information.

[0098] Step 3031: If the voltage anomaly value does not fall within the voltage safety range, determine the adjustment parameter according to the voltage anomaly value, define the adjustment parameter as the voltage warning information, and output the voltage warning information to the terminal held by the preset staff member.

[0099] The voltage warning information refers to the warning message when the voltage anomaly value of the switch cabinet does not fall within the preset voltage safety range. The adjustment database stores the adjustment parameters corresponding to different voltage anomaly values, and the adjustment database is pre-set by the staff and will not be elaborated here. If the voltage anomaly value does not fall within the voltage safety range, it indicates that the voltage of the switch cabinet is abnormal and will affect the safe operation of the switch cabinet. Then, by inputting the voltage anomaly value into the preset adjustment database, the adjustment parameter is determined, the adjustment parameter is defined as the voltage warning information, and the voltage warning information is output to the terminal held by the preset staff member, so as to give an early warning of the abnormal situation of the switch cabinet in a timely manner.

[0100] In step 3000, in order to further ensure the safe operation of the switch cabinet, it is necessary to perform a further separate analysis and calculation on the current of the switch cabinet. The current detection methods include: Step 400: Determine whether the current anomaly information contains a preset current anomaly feature.

[0101] The current anomaly feature refers to the feature that the current shows an anomaly during the operation of the switch cabinet, and the current anomaly feature is pre-set by the staff. By judging whether the current anomaly information contains a preset current anomaly feature, it is determined whether the current of the switch cabinet is normal.

[0102] Step 4000: If the current anomaly information does not contain the current anomaly feature, perform the detection with a preset mechanical operation detection method.

[0103] If the current anomaly information does not contain the current anomaly feature, it indicates that the current of the switch cabinet is normal and there will be no alarm. Then, perform the detection with a preset mechanical operation detection method. The mechanical operation detection method refers to the method of detecting the mechanical parts and operating equipment inside the switch cabinet. The mechanical operation detection method is steps 500 - step 507.

[0104] Step 4001: If the current anomaly information contains the current anomaly feature, determine the current anomaly location according to the current anomaly information.

[0105] The current anomaly location refers to the specific location where the current anomaly feature appears in the switch cabinet. If the current anomaly information contains the current anomaly feature, it indicates that the current of the switch cabinet is abnormal. Then, analyze the current anomaly feature from the current anomaly information, and retrieve the location corresponding to the current anomaly feature, so as to determine the current anomaly location.

[0106] Step 401: Determine the reference current value according to the model information.

[0107] The reference current value refers to the standard current value of the switchgear. The reference current value is obtained by retrieving it from the model information.

[0108] Step 402: Retrieve the detected current value according to the current detection information.

[0109] The detected current value refers to the actual current value obtained by the current sensor of the switchgear. The detected current value is obtained by retrieving it from the current detection information.

[0110] Step 403: Calculate the difference between the reference current value and the detected current value and use it as the current anomaly value.

[0111] The current anomaly value refers to the value of the deviation degree between the actual operating current detected by the switchgear and the standard current. By analyzing and calculating the difference between the reference current value and the detected current value, this difference is used as the current anomaly value.

[0112] Step 404: Determine whether the current anomaly value falls within a preset safe current range.

[0113] The safe current range refers to a range of allowable current fluctuations set to ensure the normal operation of the switchgear, and the safe current range is preset by the staff. By judging whether the current anomaly value falls within the preset safe current range, it is determined whether the current anomaly value will affect the switchgear.

[0114] Step 4040: If the current anomaly value falls within the safe current range, re-obtain the device operation parameter information.

[0115] If the current anomaly value falls within the safe current range, it means that the current anomaly value of the switchgear will not affect the switchgear, then re-obtain the device operation parameter information.

[0116] Step 4041: If the current anomaly value does not fall within the safe current range, determine the current repair location according to the current anomaly location, define the current repair location as the current warning information, and output the current warning information to the preset terminal held by the staff.

[0117] The current warning information refers to a warning message generated when the abnormal current value of the switch cabinet does not fall within the safe current range. If the abnormal current value does not fall within the safe current range, it indicates that the abnormal current value of the switch cabinet will have an impact on the switch cabinet. Then, by retrieving the position of the current fluctuation in the abnormal current position in the current detection information, and taking the component position corresponding to the abnormal current position as the current repair position, the current warning information is determined, and the current warning information is output to the terminal held by the preset staff, so as to give an early warning of the abnormal situation of the switch cabinet in a timely manner.

[0118] In step 4000, in order to further ensure the safe operation of the switch cabinet, it is necessary to perform further separate analysis and calculation on the mechanical parts and operating equipment in the switch cabinet. The mechanical operation detection method includes: Step 500: Obtain the mechanical operation detection information of the high-voltage medium-mounted switch cabinet.

[0119] The mechanical operation detection information refers to the data information reflecting the operating states of the mechanical parts and operating equipment in the switch cabinet, which is obtained through a preset monitoring system. The monitoring system refers to monitoring the operating states of the mechanical parts and operating equipment in the switch cabinet, and the mechanical operation detection information includes the part distribution information.

[0120] Step 501: Determine whether the preset normal operation characteristics are included in the mechanical operation detection information.

[0121] The normal operation characteristics are the characteristics of the normal operation of the mechanical parts and operating equipment in the switch cabinet, which are preset by a staff member. By judging whether the preset normal operation characteristics are included in the mechanical operation detection information, the internal operation of the switch cabinet can be determined to be normal or not.

[0122] Step 5010: If the preset normal operation characteristics are included in the mechanical operation detection information, perform detection by the preset foreign object approach detection method.

[0123] If the preset normal operation characteristics are not included in the mechanical operation detection information, it indicates that the internal operation of the switch cabinet is normal, and then perform detection by the preset foreign object approach detection method. The foreign object approach detection method refers to a method for detecting the ventilation openings of the switch cabinet to determine whether there are obstacles. The foreign object approach detection method is steps 600 - 608.

[0124] Step 5011: If the preset normal operation characteristics are not included in the mechanical operation detection information, determine the mechanical reference state value according to the model information.

[0125] If the preset normal operation characteristics are not included in the mechanical operation detection information, it indicates that there is an abnormality in the internal operation of the switch cabinet, and then retrieve the mechanical reference state value through the model information.

[0126] Step 502: Determine the mechanical detection status value based on the mechanical operation detection information.

[0127] The mechanical detection status value refers to the status reference value for the operation of the mechanical parts and internal equipment of the switchgear. By comparing the parameters collected during operation in the mechanical operation detection information with the parameters of the preset normal state, and using the compared parameters as the mechanical detection status value. The parameters of the normal state refer to the standard state parameters of the mechanical parts and internal equipment of the switchgear during operation, and the parameters of the normal state are pre-set by the staff.

[0128] Step 503: Determine the abnormal value based on the mechanical reference status value and the mechanical detection status value.

[0129] The abnormal value refers to the degree of abnormality of the mechanical parts or internal equipment of the switchgear during operation. By analyzing and calculating the deviation value between the mechanical reference status value and the mechanical detection status value, and using this deviation value as the abnormal value.

[0130] Step 504: Determine the mechanical abnormal position based on the mechanical operation detection information.

[0131] The mechanical abnormal position refers to the specific position where the mechanical parts or internal equipment of the switchgear operate abnormally. By selecting the positions where abnormalities occur in the mechanical operation detection information, the mechanical abnormal position can be obtained.

[0132] Step 505: Determine the mechanical maintenance parameters based on the mechanical abnormal position and the abnormal value, define the mechanical maintenance parameters as mechanical maintenance warning information, and output the mechanical maintenance warning information to the preset terminal held by the staff.

[0133] The mechanical maintenance parameters refer to the parameter information that needs to be repaired. The mechanical maintenance warning information refers to the message that is warned after the mechanical maintenance parameters are integrated, and is a warning notice sent to the preset staff terminal. Different mechanical maintenance parameters corresponding to different mechanical abnormal positions and abnormal values are stored in the mechanical maintenance database. By inputting the mechanical abnormal position and the abnormal value into the preset mechanical maintenance database, the mechanical maintenance parameters can be obtained, and the mechanical maintenance parameters are defined as mechanical maintenance warning information, and the mechanical maintenance warning information is output to the preset terminal held by the staff, so as to give an early warning of the abnormal situation of the switchgear in time.

[0134] In step 5010, in order to further ensure the safe operation of the switchgear, it is necessary to perform a further separate analysis and calculation on the surroundings of the ventilation openings of the switchgear. The foreign object approach detection method includes: Step 600: Obtain the foreign object detection information of the high-voltage medium-mounted switchgear.

[0135] The foreign object detection information refers to the image information obtained by a preset camera for detecting the area around the ventilation opening of the switch cabinet. The foreign object detection information of the switch cabinet is obtained through the camera.

[0136] Step 601: Determine whether the foreign object detection information contains preset foreign object features.

[0137] The foreign object feature refers to the appearance of garbage, other equipment, or animals around the ventilation opening, which is the foreign object feature. By determining whether the foreign object detection information contains the preset foreign object feature, it is determined whether there are foreign objects around the ventilation opening.

[0138] Step 6010: If the foreign object detection information does not contain foreign object features, re-obtain the device operation parameter information.

[0139] If the foreign object detection information does not contain foreign object features, it means that there are no foreign objects that will block ventilation around the ventilation opening, so re-obtain the device operation parameter information.

[0140] Step 6011: If the foreign object detection information contains foreign object features, select the foreign object image according to the foreign object detection information and the foreign object feature.

[0141] The foreign object image refers to the photo taken of the foreign object around the ventilation opening. If the foreign object detection information contains foreign object features, the images in the foreign object detection information that meet the foreign object features are selected to obtain the foreign object image.

[0142] Step 602: Determine the foreign object position and foreign object type according to the foreign object image.

[0143] The foreign object position refers to the specific position of the foreign object around the ventilation opening. The foreign object type refers to the type of the foreign object around the ventilation opening. The foreign object types include dust, animals, other sundries, etc. A coordinate system is established in the foreign object detection information, and the foreign object position is determined by the position covered by the foreign object in the coordinate system. The foreign object image is input into the preset type database to obtain the foreign object type. Different foreign object types corresponding to different foreign object images are stored in the type database. The type database is preset by the staff and will not be elaborated here.

[0144] Step 603: Determine whether the foreign object is static according to the foreign object detection information.

[0145] Static means that the foreign object around the ventilation opening is in a stationary state. By obtaining the foreign object detection information in real time and analyzing the movement of the foreign object over time in the foreign object detection information, it is determined whether it is static. By judging the foreign object detection information to determine whether the foreign object is static, the treatment method for the foreign object is determined.

[0146] Step 6030: If the foreign object is static, determine whether the foreign object type is the preset blowing type.

[0147] The blowing type refers to the types of foreign objects that can be blown, such as small foreign objects like dust. The blowing type is preset by the staff, and different types need to be processed in different ways, such as by suction, grasping, or capturing. If the foreign object is static, indicating that the foreign objects around the ventilation opening are in a stationary state, then it is determined whether to blow by judging whether the foreign object type is the preset blowing type.

[0148] Step 60300: If the foreign object type is the blowing type, determine the dust value based on the foreign object image.

[0149] The dust value refers to the amount of dust around the ventilation opening. If the foreign object type is the blowing type, indicating that the foreign object can be blown, then the dust value is obtained by inputting the foreign object image into a preset dust database. The dust database stores the dust values corresponding to different foreign object images, and the dust database is preset by the staff.

[0150] Step 604: Determine the blowing parameters based on the dust value, define the blowing parameters as the blowing warning information, and output the blowing warning information to a preset terminal held by the staff.

[0151] The blowing parameters refer to the data used to guide the operation of cleaning the foreign objects in the ventilation opening. The blowing warning information refers to the warning notice sent to the preset staff terminal after the blowing parameters are integrated. The blowing database stores the blowing parameters corresponding to different dust values, and the blowing database is preset by the staff. Input the dust value into the preset blowing database to obtain the blowing parameters, and output the blowing warning information to the preset terminal held by the staff, so as to give an early warning of the abnormal situation of the high-voltage medium-mounted switchgear in a timely manner.

[0152] Step 60301: If the foreign object type is not the blowing type, determine the foreign object size based on the foreign object image.

[0153] The foreign object size refers to the volume size of the foreign object around the ventilation opening. The foreign object position refers to the specific position of the foreign object around the ventilation opening. If the foreign object type is not the blowing type, indicating that the foreign object cannot be blown, then the foreign object size is determined by the foreign object type in the foreign object image and the area covered by the foreign object in the coordinate system.

[0154] Step 605: Determine the grasping position based on the foreign object position.

[0155] The grasping position refers to the specific position where the foreign object around the ventilation opening is grabbed. Determine the position on the outside of the foreign object that can be grabbed based on the foreign object position and the foreign object size as the grasping position.

[0156] Step 606: Determine the grasping force based on the foreign object type and the foreign object size.

[0157] The grasping force refers to the force for moving a foreign object. The type and size of the foreign object are input into a preset force database to obtain the grasping force. The force database stores the grasping forces corresponding to different types and sizes of foreign objects, and the force database is preset by the staff.

[0158] Step 607: Determine the grasping warning information based on the grasping position and the grasping force, and output the grasping warning information to a preset terminal held by the staff.

[0159] The grasping warning information refers to the specific information about the force and position of grasping a foreign object. By integrating the grasping position and the grasping force, and using the integrated information as the grasping warning information, and outputting the grasping warning information to a preset terminal held by the staff, the abnormal situation of the switch cabinet can be pre-warned in time.

[0160] Step 6031: If the foreign object is not static, determine the estimated position in real time according to the position of the foreign object.

[0161] The estimated position refers to the position estimated when grasping a dynamic object. If the foreign object is not static, it means the foreign object can move, and it may be an animal. Then, according to the foreign object detection information, determine the movement trajectory of the foreign object position, and analyze the movement trajectory of the foreign object position to determine the estimated position.

[0162] Step 608: Determine the real-time falling parameter according to the estimated position, define the real-time falling parameter as the capture warning information, and output the capture warning information to a preset terminal held by the staff.

[0163] The real-time falling parameter refers to the operating parameter for a preset capture net to grasp a foreign object, which needs to be obtained in real time because the foreign object is not static. The capture warning information refers to the warning information for capturing a non-static foreign object. The capture neural network model is obtained by the staff pre-inputting different estimated positions and training. Input the estimated position into the preset capture neural network model for analysis to obtain the real-time falling parameter, define the real-time falling parameter as the capture warning information, and output the capture warning information to a preset terminal held by the staff, so as to pre-warn the abnormal situation of the switch cabinet in time.

[0164] In step 1061, in order to further ensure the safe operation of the switch cabinet, after outputting the temperature warning information to a preset terminal held by the staff, it further includes: Step 700: Re-obtain the equipment operation parameter information after the terminal operation of the high-voltage draw-out switchgear and use it as the equipment abnormal information.

[0165] Device abnormal information refers to the operating parameter information corresponding to the abnormal situation of the switch cabinet after warning. Re-obtain the device operating parameter information after the terminal operation of the switch cabinet and use it as the device abnormal information.

[0166] Step 701: Determine whether the warning is successfully lifted according to the device abnormal information.

[0167] Determine whether the lifting is successful by whether the device abnormal information is consistent with the preset normal operating parameter information. The normal operating parameter information refers to the standard parameters during the operation of the high-voltage medium-mounted switch cabinet, and the normal operating parameter information is preset by the staff.

[0168] Step 7010: If the device abnormal information is not successfully lifted, determine the warning information currently output to the preset terminal held by the staff according to the device operating parameter information and use it as the alarm warning information.

[0169] The alarm warning information refers to the information that the alarm is continuing. If the device abnormal information is not successfully lifted, indicating that the alarm needs to continue, determine the warning information currently output to the preset terminal held by the staff according to the device operating parameter information and use it as the alarm warning information.

[0170] Step 702: Determine the call type and call duration according to the alarm warning information.

[0171] The call type refers to the warning type of the abnormal alarm in progress. The call types include the types corresponding to temperature warning information, voltage warning information, current warning information, mechanical maintenance warning information, air blowing warning information, and capture warning information. The call duration refers to the duration of the alarm call. Different call types corresponding to different call durations are stored in the warning database, and the warning database is preset by the staff. Input the alarm warning information into the warning database to determine the call type, and analyze the alarm warning information to determine the call duration.

[0172] Step 703: Determine the duration emergency range according to the call type.

[0173] The duration emergency range refers to the time emergency range that needs to be responded to according to the different abnormal situations of different switch cabinets corresponding to different call types. Different call types correspond to different duration emergency ranges. Input the call type into the preset emergency database to obtain the duration emergency range. Different duration emergency ranges corresponding to different call types are stored in the emergency database, and the emergency database is preset by the staff and will not be elaborated here.

[0174] Step 704: Determine whether the call duration falls within the duration emergency range.

[0175] Whether to continue the alarm is determined by judging whether the call duration falls within the emergency duration interval.

[0176] Step 7040: If the call duration does not fall within the emergency duration interval, continue the alarm.

[0177] If the call duration does not fall within the emergency duration interval, it means the call duration is short, then the alarm will continue and wait for the staff to handle it.

[0178] Step 7041: If the call duration falls within the emergency duration interval, power is cut off.

[0179] If the call duration falls into the emergency interval, it means that the call time is very long. In order not to affect the use and operation safety of the switch cabinet, the power is cut off.

[0180] Step 7011: If the device abnormality information is successfully resolved, the warning will stop.

[0181] If the equipment abnormality information is successfully resolved, it means that the abnormality of the switch cabinet has been resolved, and the alarm will stop.

[0182] In step 7040, in order to further ensure the safe operation of the switch cabinet, when the alarm continues, the following steps are included: Step 800: Determine the alarm location and alarm time point according to the alarm warning information.

[0183] The alarm position refers to the position in the switch cabinet where the foreign matter is abnormal and the warning is triggered. The alarm time point refers to the time point when the alarm is in progress.

[0184] Step 801: Determine a call benchmark duration according to the alarm location.

[0185] The call base duration refers to the base duration for alarm after a problem occurs at the alarm location. The call database stores the call base durations corresponding to different alarm locations. Different alarm locations correspond to different call base durations. The alarm location is input into the preset call database to obtain the call base duration, and the call base duration is determined by the alarm location.

[0186] Step 802: Determine a duration deviation value according to the call reference duration and the call duration.

[0187] The duration deviation value refers to the difference between the call benchmark duration and the call duration. The duration deviation value is determined by analyzing and calculating the difference between the call benchmark duration and the call duration.

[0188] Step 803: Determine whether the duration deviation value is less than a preset emergency deviation value.

[0189] The emergency deviation value refers to the reference deviation value corresponding to an emergency situation, which is preset by the staff. By determining whether the duration deviation value is less than the preset emergency deviation value, it is determined whether power needs to be cut off.

[0190] Step 8030: If it is not less than, determine the power-off information according to the alarm location and the preset power-off database, and control the high-voltage medium-mounted switch cabinet to cut off power with the power-off information.

[0191] The power-off database stores the power-off information corresponding to different alarm locations. The power-off information refers to the location where power needs to be cut off and the part where power needs to be cut off. If it is not less than, it means that the time for continuous calling is too long, then the alarm location is input into the preset power-off database, so as to determine the power-off information, and control the switch cabinet to cut off power with the power-off information.

[0192] Step 8031: If it is less than, obtain the device terminal information corresponding to the terminal held by the staff.

[0193] The device terminal information refers to the device information corresponding to the receiving end that receives other information such as the early warning information of the switch cabinet. If it is less than, it means that the alarm can continue, then obtain the device terminal information corresponding to the terminal held by the staff.

[0194] Step 804: Determine whether the alarm time point falls within the preset acceptable time interval.

[0195] The acceptable time interval refers to the time interval that the staff can receive. The acceptable time interval can be the working time of the staff, which is preset by the staff. By determining whether the alarm time point falls within the preset acceptable time interval, the processing method is determined.

[0196] Step 8040: If the alarm time point falls within the acceptable time interval, determine other receiving ends according to the device terminal information and the received alarm information, and send the alarm early warning information to other receiving ends.

[0197] Other receiving ends refer to the standby receiving ends when the problem is not processed within a certain time after the alarm is issued. If the alarm time point falls within the acceptable time interval, it means that the staff can receive the received alarm information. Different received alarm information corresponds to different other receiving ends. Therefore, by retrieving the received alarm information corresponding to the received alarm information from the device terminal information, other receiving ends are obtained, and the alarm early warning information is sent to other receiving ends.

[0198] Step 8041: If the alarm time point does not fall within the acceptable time interval, send the alarm early warning information to the preset unattended offline receiving end and cut off power.

[0199] The unmanned offline receiving end refers to a port that can complete information reception even under unmanned operation or system offline status. The unmanned offline receiving end is pre-set by the staff. If the alarm time point does not fall within the receivable time interval, it means that the staff is off work and no one can perform maintenance in a timely manner. Then, the alarm warning information is sent to the pre-set unmanned offline receiving end and the power is cut off.
