Technical Field

[0001] The present invention relates to the technical field of partial discharge monitoring, and in particular to a multi-scenario partial discharge monitoring and early warning method and a monitoring device. Background Art

[0002] Partial discharge monitoring is a technical means to detect partial discharge phenomenon in electrical equipment. Partial discharge phenomenon refers to the phenomenon that in the insulation system of electrical equipment, due to the local concentration of the electric field, the electric field strength in the local area may exceed the breakdown field strength of the insulating medium.

[0003] Partial discharge is usually an early manifestation of the degradation of the insulation performance of electrical equipment. By installing a partial discharge monitoring device that can monitor partial discharge on the equipment that needs to be tested, the partial discharge monitoring device can monitor the parameter changes of the equipment, so as to know the partial discharge of the equipment, find the problem before the equipment fails seriously, and notify the operator to deal with it. When the monitoring data of the partial discharge monitoring device is abnormal, the operator usually determines the abnormality of the partial discharge monitoring device after comparing the data before handling it.

[0004] When the monitoring data of the partial discharge monitoring device is abnormal, the operator needs to first determine the abnormal situation of the partial discharge monitoring device after data comparison, which makes it difficult for the operator to promptly know that the partial discharge monitoring device has an abnormality, and it is not easy to promptly deal with the partial discharge phenomenon, which needs to be improved. Summary of the invention

[0005] In order to be able to deal with the phenomenon of partial discharge in a timely manner, the present invention provides a multi-scenario partial discharge monitoring and early warning method and a monitoring device.

[0011] By adopting the above technical solution, by changing the magnetic force of the magnetic attraction device on the multi-scenario partial discharge monitoring device, the multi-scenario partial discharge monitoring device can slide downward to the reference installation range by its own gravity, thereby preventing the multi-scenario partial discharge monitoring device from having parameter detection errors due to position offset.

[0015] By adopting the above technical solution, by understanding the situation of people around the multi-scenario partial discharge monitoring device, prompting and shielding people within the reference safety distance, and outputting prompt information to prompt non-related people close to the multi-scenario partial discharge monitoring device, it is less likely that non-related people will collide with the multi-scenario partial discharge monitoring device, causing position displacement and parameter detection errors.

[0016] Optionally, the method for controlling the wind output device to stop running includes: Obtain the current location and current time of the multi-scenario partial discharge monitoring device; Determine the sun's position based on the current position and current time; According to the surrounding environment image, the position of the image corresponding to the preset glass window feature is framed as the glass window position and glass window specification; Calculate the horizontal straight-line distance between the glass window position and the actual installation position as the irradiation distance; Determine the irradiation area based on the glass window specifications, irradiation distance and sun position; When the actual installation position falls into the irradiation area, the actual temperature value of the multi-scenario partial discharge monitoring device is obtained; When the actual temperature value reaches the preset reference temperature value, the shielding position is determined according to the irradiation area and the actual installation position; The preset shielding device is controlled to perform shielding according to the shielding position.

[0017] By adopting the above technical scheme, the position of the sun and the conditions around the multi-scenario partial discharge monitoring device are understood to obtain the sun's irradiation area, and when the actual installation position falls within the irradiation area and the actual temperature value is greater than the reference temperature value, the shielding device is controlled to shield the sun, thereby making it less likely for the multi-scenario partial discharge monitoring device to produce parameter deviations due to temperature, thereby improving the accuracy of detecting the partial discharge conditions of the device to be tested, and being able to deal with the partial discharge phenomenon in a timely manner.

[0018] Optionally, the method for controlling the preset shielding device to perform shielding includes: Obtain the ambient humidity value of the multi-scenario partial discharge monitoring device; When the ambient humidity value is greater than the preset reference humidity value, the shielding distance is determined according to the shielding position and the actual installation position; Determine the shading shadow area according to the shading distance and the preset shading specifications; Determine the installation area based on the installation specifications; Determine the tilt angle based on the device area and the shaded area; Controlling the shielding device to tilt according to the tilt angle, and updating the surrounding humidity value according to a preset unit time; Calculate the difference between the ambient humidity values ​​before and after the update and use it as the humidity deviation value; Determine the humidity deviation speed based on the humidity deviation value and unit time; When the humidity deviation speed is increasing, the blowing power is determined according to the humidity deviation speed, and the preset wind output device is controlled according to the blowing power to blow air to the multi-scenario partial discharge monitoring device.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Reference Figure 1 The embodiment of the present application discloses a multi-scenario partial discharge monitoring device, including a partial discharge sensor 2 for detecting partial discharge signals, a data transceiver 3 for outputting parameters detected by the partial discharge sensor to a server, and a magnetic device for fixing the partial discharge sensor 2 to a device to be tested 1. The partial discharge sensor 2 is generally installed on a side wall of a preset device to be tested 1. The data transceiver 3 may be an antenna.

[0030] Reference Figure 2 The present application embodiment discloses a multi-scenario partial discharge monitoring and early warning method, comprising the following steps: Step S100: acquiring the current detection value of the device under test 1 and the discharge fluctuation image of the multi-scenario partial discharge monitoring device.

[0031] The current detection value refers to the current parameter corresponding to the device under test 1 at the current time when the partial discharge situation needs to be detected. The parameter detected by the ammeter preset on the device under test 1 is used as the current detection value. The discharge fluctuation image refers to the fluctuation image detected by the multi-scenario partial discharge monitoring device on the device under test 1 when the device under test 1 generates partial discharge. The image formed by the parameters preset in the current sensor detection is called by the system as the discharge fluctuation image. In this example, the device under test 1 can be a substation switch cabinet.

[0032] Step S101: when the current detection value is not greater than the preset reference current value, continue to obtain the current detection value.

[0033] The reference current value refers to the minimum current parameter corresponding to partial discharge of the device under test 1, which is set and stored by the operator in advance. When the current detection value is not greater than the reference current value, it means that there is no partial discharge in the device under test 1, so the current detection value continues to be obtained.

[0034] Step S102 : when the current detection value is greater than a preset reference current value, calculating a difference between the current detection value and the reference current value and using it as a current deviation value.

[0035] The current deviation value refers to the deviation value between the current detection value and the reference current value. When the current detection value is greater than the reference current value, it indicates that partial discharge occurs in the device under test 1. Therefore, the difference between the current detection value and the reference current value is calculated as the current deviation value.

[0036] Step S103: determining the current estimated amplitude according to the current deviation value.

[0037] The current estimated amplitude refers to the maximum fluctuation amplitude of the current fluctuation of the multi-scenario partial discharge monitoring device corresponding to the partial discharge situation of the device under test 1. The current estimated amplitude is matched from the preset discharge database through the current deviation value. The discharge database stores the current estimated amplitudes corresponding to different current deviation values. The discharge database is a database set by humans and will not be described in detail here.

[0038] Step S104: retrieving the corresponding actual discharge amplitude from the discharge fluctuation image based on the current deviation value.

[0039] The actual discharge amplitude refers to the actual amplitude of the current fluctuation of the multi-scenario partial discharge monitoring device corresponding to the partial discharge situation of the device under test 1, and the discharge arc at the time point corresponding to the current deviation value is retrieved from the discharge fluctuation image as the actual discharge amplitude.

[0040] Step S105: Determine whether the actual discharge amplitude is greater than the estimated current amplitude.

[0041] By determining whether the actual discharge amplitude is greater than the estimated current amplitude, it is determined whether the multi-scenario partial discharge monitoring device has an abnormality.

[0042] Step S106: when the actual discharge amplitude is greater than the estimated current amplitude, outputting a preset alarm processing information.

[0043] When the actual discharge amplitude is greater than the estimated current amplitude, it indicates that the device under test 1 has partial discharge, so the preset alarm processing information is output to the terminal held by the operator. The alarm processing information refers to the prompt information that prompts the operator that the device under test 1 has partial discharge and issues an early warning, which is preset and stored by the operator.

[0044] Step S107 : when the actual discharge amplitude is not greater than the estimated current amplitude, determining the actual fluctuation distance corresponding to the actual discharge amplitude according to the discharge fluctuation image.

[0045] The actual fluctuation distance refers to the distance corresponding to the actual discharge amplitude in the discharge fluctuation image. When the actual discharge amplitude is not greater than the estimated current amplitude, it means that no local discharge occurs in the device under test 1, and there is an abnormality in the multi-scenario local discharge monitoring device. Therefore, the distance corresponding to the actual discharge amplitude is retrieved in real time from the discharge fluctuation image as the actual fluctuation distance.

[0046] Step S108: When the actual fluctuation distance does not exceed the preset reference fluctuation distance, continue to obtain the current detection value and the discharge fluctuation image.

[0047] The reference fluctuation distance refers to the maximum distance that the actual discharge amplitude is allowed to fluctuate, which is set and stored in advance by the operator. When the actual fluctuation distance does not exceed the reference fluctuation distance, it means that there is no need to output the preset alarm information, so the current detection value and the discharge fluctuation image continue to be obtained. The alarm information refers to the prompt information that prompts the operator that the multi-scenario partial discharge monitoring device has an abnormality, which is set and stored in advance by the operator.

[0048] Step S109: When the actual fluctuation distance exceeds the preset reference fluctuation distance, output a preset alarm message.

[0049] When the actual fluctuation distance does not exceed the benchmark fluctuation distance, it indicates that the preset alarm information needs to be output, so the alarm information is output to the terminal held by the operator, so that an abnormality occurring in the multi-scenario local discharge monitoring device can be early warned, and the abnormality of the multi-scenario local discharge monitoring device can be handled in time, and the phenomenon of local discharge can be handled.

[0050] It also includes the method before outputting the preset warning information: Step S200: Acquire image detection information of the multi-scenario partial discharge monitoring device.

[0051] The image detection information refers to the image corresponding to the multi-scenario partial discharge monitoring device installed on the device under test 1. The multi-scenario partial discharge monitoring device installed on the device under test 1 is photographed by cameras preset around the device under test 1 and the photographed image is used as the image detection information.

[0052] Step S201: determining the actual installation position according to the image detection information and the preset discharge device characteristics.

[0053] The discharge device characteristics refer to the shape, color and other characteristics of the multi-scenario partial discharge monitoring device. The actual installation position refers to the actual installation position of the multi-scenario partial discharge monitoring device. The image corresponding to the discharge device characteristics is selected from the image detection information, and the position corresponding to the selected image is obtained from the image detection information as the actual installation position.

[0054] Step S202: Determine whether the actual installation position falls within a preset reference installation range.

[0055] The reference installation range refers to the reference installation range corresponding to the partial discharge situation of the device under test 1 used by the multi-scenario partial discharge monitoring device, which is set and stored in advance by the operator. By determining whether the actual installation position falls within the reference installation range, it is determined whether the multi-scenario partial discharge monitoring device has a parameter detection error due to position offset.

[0056] Step S203: When the actual installation position falls within the reference installation range, continue to output the preset alarm processing information.

[0057] When the actual installation position falls within the reference installation range, it indicates that the multi-scenario partial discharge monitoring device does not have parameter detection errors due to position offset, so it continues to output alarm processing information to the terminal held by the operator to facilitate the operator to handle partial discharge situations in the device 1 under test.

[0058] Step S204: When the actual installation position does not fall within the reference installation range, the minimum distance between the actual installation position and the reference installation range is calculated to determine the reset vector distance.

[0059] The reset vector distance refers to the vector distance that the multi-scenario partial discharge monitoring device is reset to within the reference installation range. When the actual installation position does not fall within the reference installation range, it means that the multi-scenario partial discharge monitoring device has parameter detection errors due to position offset. Therefore, the straight line vector between the actual installation position and the reference installation range is calculated, and the straight line vector with the smallest distance value is selected as the reset vector distance.

[0060] Step S205: controlling the multi-scenario partial discharge monitoring device to reset according to the reset vector distance by a preset reset method.

[0061] The reset method refers to a method for controlling the multi-scenario partial discharge monitoring device to reset. The specific steps of the reset method refer to steps S300 to S405. The multi-scenario partial discharge monitoring device is controlled to reset by the reset method through the reset vector distance, so that the multi-scenario partial discharge monitoring device is not prone to parameter detection errors due to position offset.

[0062] The preset reset methods include: Step S300: Obtain device specifications of the multi-scenario partial discharge monitoring device.

[0063] Device specifications refer to parameter specifications such as size and weight of the multi-scenario partial discharge monitoring device. The system retrieves parameter specifications such as size and weight corresponding to the multi-scenario partial discharge monitoring device as device specifications.

[0064] Step S301: Retrieve a reference weight value according to device specifications.

[0065] The reference weight value refers to the weight value of the multi-scenario partial discharge monitoring device, and the weight parameter is retrieved from the device specifications as the reference weight value.

[0066] Step S302: determining the magnetic force adjustment power according to the reference weight value.

[0067] The magnetic adjustment power refers to the power of the magnetic device on the multi-scenario partial discharge monitoring device after adjustment. The magnetic adjustment power is matched from the preset magnetic database through the reference weight value. The magnetic database stores the magnetic adjustment powers corresponding to different reference weight values. The magnetic database is a database set by humans and will not be described in detail here. The magnetic device refers to a device used to install the multi-scenario partial discharge monitoring device on the side wall of the device to be tested 1. The magnetic device can adjust the magnitude of the magnetic force by adjusting the current.

[0068] Step S303: Determine the straight-line distance between the multi-scenario partial discharge monitoring device and the ground as the vertical movement distance according to the actual installation position.

[0069] The vertical moving distance refers to the vertical straight-line distance between the multi-scenario partial discharge monitoring device and the ground, and is calculated by calculating the straight-line distance between the actual installation position and the preset ground position as the vertical moving distance. The ground position refers to the position of the ground corresponding to the multi-scenario partial discharge monitoring device, which is preset and stored by the operator.

[0070] Step S304: Determine whether the reset vector distance is a positive value.

[0071] By determining whether the reset vector distance is a positive value, it is determined whether the multi-scenario partial discharge monitoring device moves upward or downward.

[0072] Step S305: If the reset vector distance is a positive value and the vertical moving distance intersects with the reference installation range, each intersection point is determined according to the vertical moving distance and the reference installation range, and the intersection point closest to the actual installation position is defined as the selected intersection point.

[0073] The selected intersection point refers to the intersection point on the benchmark installation range when the multi-scenario partial discharge monitoring device is vertically moved. When the reset vector distance is a positive value and intersects the vertical movement distance with the benchmark installation range, it means that the multi-scenario partial discharge monitoring device needs to move vertically downward. Therefore, the point where the vertical movement distance intersects with the benchmark installation range is used as the intersection point, and the intersection point corresponding to the minimum straight line distance is selected as the selected intersection point.

[0074] Step S306: Determine a selected moving distance according to the selected intersection point and the vertical moving distance.

[0075] The selected moving distance refers to the moving distance that the multi-scenario partial discharge monitoring device moves vertically to the selected intersection point, and the moving distance between the selected intersection point and the actual installation position is retrieved from the vertical moving distance as the selected moving distance.

[0076] Step S307: adjusting the power output to the magnetic device preset on the multi-scenario partial discharge monitoring device according to the magnetic force to control the movement, and outputting the preset reference power to the magnetic device when the actual installation position coincides with the selected intersection point.

[0077] By controlling the magnetic device to adjust the power operation with magnetic force, the multi-scenario partial discharge monitoring device can slide vertically downward on the device to be tested 1 by its own weight to select the moving distance, and when the actual installation position coincides with the selected intersection point, it means that the multi-scenario partial discharge monitoring device has moved to the reference installation range, so the preset reference power is output to the magnetic device to fix the multi-scenario partial discharge monitoring device. The reference power refers to the reference power corresponding to the magnetic device when fixing the multi-scenario partial discharge monitoring device, and the reference power is formed by the operator's pre-setting and storage.

[0078] The preset reset methods also include: Step S400: If the reset vector distance is not a positive value, the suction power is determined according to the reference weight value and the reference power.

[0079] The suction power refers to the power of the wind output device for suction. When the reset vector distance is not a positive value, it means that the multi-scenario partial discharge monitoring device needs to move upward. The suction force is calculated by the reference weight value, and the suction power is matched from the preset suction database by the suction force. The wind output device refers to a device installed on the device to be tested 1 and capable of suction or blowing. The wind output device can move horizontally.

[0080] The calculation method of suction force includes: F s =F net -K×I×N×A×μ+mg,F net The force required for the operator to adsorb the multi-scenario partial discharge monitoring device, F s is the suction force corresponding to the suction power, K is the proportional constant of the magnetic force corresponding to the reference power, I is the current passing through the magnetic device corresponding to the reference power, N is the number of coil turns of the magnetic device, A is the area of ​​the magnetic device, μ is the magnetic permeability of the magnetic device, m is the reference weight value of the multi-scenario partial discharge monitoring device, and g is the acceleration of gravity. net , A, K, N, μ and I are adjusted and set by those skilled in the art according to actual conditions. The suction database stores suction powers corresponding to different suction forces. The suction database is a database set manually and will not be described in detail here.

[0081] Step S401: Determine the reset direction according to the reset vector distance.

[0082] The reset direction refers to the direction in which the multi-scenario partial discharge monitoring device moves to within the reference installation range, and the reset direction is retrieved from the reset vector distance.

[0083] Step S402: Determine the moving time according to the suction power and the reset vector distance.

[0084] Moving time refers to the time required for the multi-scenario partial discharge monitoring device to move to the reference installation range. The moving time is matched from the suction database through the suction power and the reset vector distance. The suction database also stores the moving time corresponding to different suction powers and reset vector distances, which will not be elaborated here.

[0085] Step S403: controlling the preset wind output device to run according to the suction power and the reset direction, and controlling the wind output device to stop running when the running time of the wind output device reaches the moving time.

[0086] By controlling the wind output device to operate with suction power and reset direction, the multi-scenario local discharge monitoring device can be moved to the reference installation range by adsorbing the multi-scenario local discharge monitoring device through the suction device, and when the running time of the wind output device reaches the moving time, it means that the multi-scenario local discharge monitoring device is located in the reference installation range, so the wind output device is controlled to stop running, so that the multi-scenario local discharge monitoring device is not prone to parameter detection errors due to position offset.

[0087] The method for controlling the wind power output device after stopping operation includes: Step S500: Acquire the surrounding environment image of the multi-scenario partial discharge monitoring device.

[0088] The surrounding environment image refers to the image around the multi-scenario partial discharge monitoring device, and the image around the multi-scenario partial discharge monitoring device is taken by a camera preset on the device under test 1 as the surrounding environment image.

[0089] Step S501: an image corresponding to a preset person feature is selected according to the surrounding environment image as a person detection image.

[0090] Character features refer to the characteristics of a character such as posture, color, and shape, which are preset and stored by the operator. Character detection images refer to images with character features in the surrounding environment images. The image corresponding to the character features is selected from the surrounding environment images as the character detection image.

[0091] Step S502: determining the position and shape of the person according to the person detection image.

[0092] The person position refers to the position where the person appears in the person detection image, and the person shape refers to the shape corresponding to the person appearing in the person detection image. The position corresponding to the person detection image in the surrounding environment image is used as the person position, and the shape corresponding to the box selected in the person detection image is used as the person shape.

[0093] Step S503: Calculate the spacing distance according to the person's position and the actual installation position.

[0094] The interval distance refers to the straight-line distance between the position of the person and the actual installation position. The straight-line distance between the position of the person and the actual installation position is calculated as the interval distance.

[0095] Step S504: Determine whether the interval distance is less than a preset reference safety distance.

[0096] The reference safety distance refers to the minimum distance that can be allowed between the multi-scenario partial discharge monitoring device and a person. The reference safety distance is set in advance by those skilled in the art and will not be described in detail here. By determining whether the interval distance is less than the reference safety distance, it is determined whether there is a situation where an unrelated person collides with the multi-scenario partial discharge monitoring device, causing a position shift and a parameter detection error.

[0097] Step S505: when the interval distance is less than the preset reference safety distance, determining person detection information according to the person detection image.

[0098] Person detection information refers to the facial information corresponding to the person within the reference safety distance. When the interval distance is less than the reference safety distance, it means that an unrelated person has collided with the multi-scenario partial discharge monitoring device, resulting in position displacement and parameter detection error. Therefore, the person detection image and preset facial features are used to identify the person's facial information as the person detection information.

[0099] Step S506: when the person detection information is not entered into the preset portrait database, controlling the preset shielding device to shield according to the person's position until the person detection information does not appear in the surrounding environment image.

[0100] The portrait database refers to a database storing person detection information corresponding to relevant persons. The portrait database is set in advance by those skilled in the art and will not be described in detail here.

[0101] When the person detection information is entered into the portrait database, it means that there is no situation where an unrelated person collides with the multi-scene partial discharge monitoring device, causing position displacement and parameter detection error, so the person detection image continues to be determined. When the person detection information is not entered into the portrait database, it means that there is a situation where an unrelated person collides with the multi-scene partial discharge monitoring device, causing position displacement and parameter detection error, so the multi-scene partial discharge monitoring device is shielded by the person's position by controlling the preset shielding device until no person detection information appears in the surrounding environment image. The shielding device refers to a device that is arranged on the device to be tested 1 and is used to protect the multi-scene partial discharge monitoring device from abnormal conditions such as position displacement caused by collision, direct sunlight, and humidity. The shielding device includes a mechanical arm and a baffle, and the mechanical arm clamps the baffle for shielding protection.

[0102] Step S507: When the interval distance is not less than a preset reference safety distance, the person position and the person shape are updated according to the person detection image and a preset unit time.

[0103] When the interval distance is not less than the reference safety distance, it means that there is no situation where the position offset and parameter detection error occurs due to the collision of unrelated personnel with the multi-scenario partial discharge monitoring device. Therefore, the position of the person detection image in the surrounding environment image is re-determined in the preset unit time as the new person position, and the shape corresponding to the re-determined person detection image is used as the person shape. The unit time refers to the time used to update the person position and person shape, and the unit time is pre-set and stored by the operator.

[0104] Step S508: Determine the moving direction of the character according to the character positions before and after the update.

[0105] The character moving direction refers to the direction in which the character moves. The vector distance between the character positions before and after the update is calculated, and the corresponding direction is retrieved from the vector distance as the character moving direction.

[0106] Step S509: When the moving direction of the person is the preset reference moving direction, continue to determine the position of the person.

[0107] The reference moving direction refers to the direction perpendicular to the direction approaching the multi-scenario partial discharge monitoring device, which is set and stored in advance by the operator. When the moving direction of the person is the reference moving direction, it means that there is no situation where an unrelated person collides with the multi-scenario partial discharge monitoring device, causing position deviation and parameter detection error, so the person's position continues to be determined.

[0108] Step S510: When the character's moving direction is not a preset reference moving direction, determining the character's vector moving distance according to the character's shapes before and after the update.

[0109] The character vector movement distance refers to the vector distance corresponding to the movement of the character. When the character's movement direction is not the reference movement direction, it means that there is an unrelated person colliding with the multi-scene partial discharge monitoring device, resulting in position offset and parameter detection error. Therefore, the quotient of the size parameters corresponding to the character shape before and after the update is calculated, and the product of the calculated quotient and the interval distance is used as the character's vector movement distance.

[0110] Step S511: Update the character's moving direction according to the character's vector moving distance.

[0111] The corresponding direction parameter is retrieved from the moving distance of the character vector as the new moving direction of the character.

[0112] Step S512: outputting preset prompt information according to the updated moving direction of the person, and after a unit time, controlling the shielding device to shield according to the updated position of the person until no person detection information appears in the surrounding environment image.

[0113] The prompt information refers to the information corresponding to prompting the person to stay away from the multi-scenario partial discharge monitoring device. If the updated person shape is smaller than the person shape before the update, it means that the person is moving away from the multi-scenario partial discharge monitoring device, so the person detection image is continued to be determined. If the updated person shape is larger than the person shape before the update, it means that the person is moving close to the multi-scenario partial discharge monitoring device, so the prompt information is output to the preset prompt device. The prompt device is used to receive the prompt information to prompt the person to stay away from the device corresponding to the multi-scenario partial discharge monitoring device.

[0114] Further, the method after determining the position and shape of the character includes: Step S5021: Determine the type of interference device according to the person detection image and the preset interference device features.

[0115] The interference device features refer to the shape and color of the interference device, which are set and stored by the operator in advance. The interference device type refers to the type of interference device. The device type corresponding to the interference device features is identified from the person detection image as the interference device type. The interference device refers to the device corresponding to the parameters that interfere with the multi-scenario partial discharge monitoring device. Step S5022: Determine interference deviation parameters according to the type of interference device.

[0116] The interference deviation parameter refers to the parameter corresponding to the output of the interference device. The interference deviation parameter is matched from the preset interference database according to the interference device type. The interference database stores the interference deviation parameters corresponding to different interference device types. The interference database is set manually and will not be described in detail here.

[0117] Step S5023: Calculate the difference between the actual discharge amplitude and the current estimated amplitude and use it as the amplitude deviation value.

[0118] The amplitude deviation value refers to the deviation value between the actual discharge amplitude and the current estimated amplitude. The difference between the actual discharge amplitude and the current estimated amplitude is calculated as the amplitude deviation value.

[0119] Step S5024: determining a discharge deviation parameter according to the amplitude deviation value.

[0120] The discharge deviation parameter refers to the deviation parameter corresponding to the deviation of the multi-scenario local discharge monitoring device. The discharge deviation parameter is matched from the discharge database through the amplitude deviation value. The discharge database also stores the discharge deviation parameters corresponding to different amplitude deviation values, which will not be elaborated here.

[0121] Step S5025: When the discharge deviation parameter is consistent with the interference deviation parameter, continue to obtain the current detection value and the discharge fluctuation image.

[0122] When the discharge deviation parameter is consistent with the interference deviation parameter, it means that the interference device interferes with the multi-scenario partial discharge monitoring device, and the multi-scenario partial discharge monitoring device does not show any abnormality, so the current detection value and the discharge fluctuation image continue to be obtained.

[0123] Step S5026: When the discharge deviation parameter is inconsistent with the interference deviation parameter, a difference between the discharge deviation parameter and the interference deviation parameter is calculated and used as the discharge deviation value.

[0124] The discharge deviation value refers to the deviation value between the discharge deviation parameter and the interference deviation parameter. When the discharge deviation parameter is inconsistent with the interference deviation parameter, it means that the interference device has not interfered with the multi-scenario local discharge monitoring device and there is an abnormality in the multi-scenario local discharge monitoring device. Therefore, the difference between the discharge deviation parameter and the interference deviation parameter is calculated as the discharge deviation value.

[0125] Step S5027: Determine whether the discharge deviation value falls within a preset reference discharge deviation range.

[0126] The reference discharge deviation range refers to the allowable variation range of the corresponding deviation parameters when the interference device interferes with the multi-scenario partial discharge monitoring device. The reference discharge deviation range is pre-set and stored by the operator.

[0127] Step S5028: When the discharge deviation value falls into the reference discharge deviation range, continue to obtain the current detection value and the discharge fluctuation image.

[0128] When the discharge deviation value falls within the reference discharge deviation range, it indicates that the change of the discharge deviation value is within the allowable range, so the current detection value and the discharge fluctuation image continue to be acquired.

[0129] Step S5029: when the discharge deviation value does not fall within the reference discharge deviation range, output a preset alarm message.

[0130] When the discharge deviation value does not fall within the benchmark discharge deviation range, it means that the change of the discharge deviation value is not within the allowable range, so the preset alarm information value is output to the terminal held by the operator, so that the multi-scenario local discharge monitoring device can be aware of the abnormal situation of the multi-scenario local discharge monitoring device when it is interfered, and then the abnormal situation of the multi-scenario local discharge monitoring device can be handled in time.

[0131] The method for controlling the wind power output device after stopping operation includes: Step S600: Acquire the current location and current time of the multi-scenario partial discharge monitoring device.

[0132] The current position refers to the geographical location of the multi-scenario partial discharge monitoring device. The geographical location corresponding to the multi-scenario partial discharge monitoring device is located by GPS as the current position. The current time refers to the time parameter value corresponding to the current position of the sun that needs to be determined. The time corresponding to the current position is queried through the network as the current time.

[0133] Step S601: Determine the sun's position based on the current position and the current time.

[0134] The sun position refers to the position of the sun at the current position and the current time. The sun position is matched from the preset irradiation database through the current position and the current time. The irradiation database stores the sun positions corresponding to different current positions and the current time. The irradiation database is a database set by humans and will not be described in detail here.

[0135] Step S602: Frame the position of the image corresponding to the preset glass window feature according to the surrounding environment image as the glass window position and glass window specification.

[0136] The glass window feature refers to the shape and other features corresponding to the glass window, which are set in advance and stored by the operator. The glass window position refers to the position where the glass window is installed, and the glass window specification refers to the size specification of the glass window corresponding to the glass window position. The image corresponding to the glass window feature is framed from the surrounding environment image, and the position of the image in the surrounding environment image is framed as the glass window position, and the shape specification corresponding to the framed image is framed as the glass window specification. The device to be tested 1 can be outdoors or indoors. In this embodiment, the device to be tested 1 is indoors.

[0137] Step S603: Calculate the horizontal straight-line distance between the glass window position and the actual installation position as the irradiation distance.

[0138] The irradiation distance refers to the distance corresponding to the sun irradiating the multi-scenario partial discharge monitoring device. The horizontal straight-line distance between the glass window position and the actual installation position is calculated as the irradiation distance.

[0139] Step S604: Determine the irradiation area according to the specifications of the glass window, the irradiation distance and the position of the sun.

[0140] The irradiation area refers to the area on the multi-scenario partial discharge monitoring device where the sun irradiates. The initial area of ​​the sun irradiation is obtained by the specifications of the glass window and the position of the sun. The correction coefficient is matched from the irradiation database according to the irradiation distance, and the irradiation area is obtained by calculating the product of the correction coefficient and the initial area. The correction coefficients corresponding to different irradiation distances are also stored in the irradiation database, which will not be described in detail here.

[0141] Step S605: When the actual installation position does not fall within the irradiation area, continue to determine the irradiation area.

[0142] When the actual installation location does not fall within the irradiation area, it means that the sun does not shine on the multi-scenario partial discharge monitoring device, so continue to determine the irradiation area.

[0143] Step S606: when the actual installation position falls into the irradiation area, obtaining the actual temperature value of the multi-scenario partial discharge monitoring device.

[0144] The actual temperature value refers to the temperature value actually detected by the multi-scenario partial discharge monitoring device at the current time. When the actual installation position falls into the irradiation area, it means that the sun shines on the multi-scenario partial discharge monitoring device. Therefore, the parameter detected by the temperature sensor preset on the multi-scenario partial discharge monitoring device is used as the actual temperature value.

[0145] Step S607: When the actual temperature value does not reach the preset reference temperature value, continue to obtain the actual temperature value.

[0146] The reference temperature value refers to the minimum temperature value when the multi-scenario partial discharge monitoring device has parameter deviation. The reference temperature value is set in advance by those skilled in the art and will not be described in detail here. When the actual temperature value does not reach the reference temperature value, it means that the multi-scenario partial discharge monitoring device will not have parameter deviation due to temperature, so the actual temperature value continues to be obtained.

[0147] Step S608: When the actual temperature value reaches a preset reference temperature value, the shielding position is determined according to the irradiation area and the actual installation position.

[0148] The shielding position refers to the position where the shielding device shades the multi-scenario partial discharge monitoring device. When the actual temperature value reaches the reference temperature value, it means that the multi-scenario partial discharge monitoring device will have parameter deviation due to temperature. Therefore, the shielding position is matched from the preset shielding database through the irradiation area and the actual installation position. The shielding database stores the shielding positions corresponding to different irradiation areas and actual installation positions. The shielding database is a manually set database and will not be described in detail here.

[0149] Step S609: controlling a preset shielding device to perform shielding according to the shielding position.

[0150] By controlling the shielding device to shield the multi-scenario partial discharge monitoring device at a shielding position, it is less likely for the multi-scenario partial discharge monitoring device to have parameter deviations due to temperature, and it is less likely for abnormal conditions of the multi-scenario partial discharge monitoring device to have judgment errors.

[0151] The method for controlling the preset shielding device to perform shielding includes: Step S700: Acquire the ambient humidity value of the multi-scenario partial discharge monitoring device.

[0152] The ambient humidity value refers to the humidity value around the multi-scenario partial discharge monitoring device, and the parameters around the multi-scenario partial discharge monitoring device are detected by a humidity sensor preset on the device under test 1 as the ambient humidity value.

[0153] Step S701: When the ambient humidity value is not greater than the preset reference humidity value, continue to obtain the ambient humidity value.

[0154] The reference humidity value refers to the minimum humidity value when the multi-scenario partial discharge monitoring device has parameter deviation. The reference humidity value is set in advance by those skilled in the art and will not be described in detail here. When the ambient humidity value is not greater than the reference humidity value, it means that the multi-scenario partial discharge monitoring device will not have parameter deviation due to humidity, so the ambient humidity value continues to be obtained.

[0155] Step S702: When the ambient humidity value is greater than a preset reference humidity value, determining the shielding distance according to the shielding position and the actual installation position.

[0156] The shielding distance refers to the distance that the shielding device shields. When the ambient humidity value is greater than the reference humidity value, it means that the multi-scenario partial discharge monitoring device will have parameter deviations due to humidity. Therefore, the straight-line distance between the shielding position and the actual installation position is calculated as the shielding distance.

[0157] Step S703: Determine the shielding shadow area according to the shielding distance and the preset shielding specification.

[0158] The shielding specification refers to the size specification corresponding to the shielding device, which is set and stored in advance by the operator. The shielding shadow area refers to the area of ​​the shadow corresponding to the sun shielded by the shielding device. The shielding shadow area is matched from the shielding database through the shielding distance and the shielding specification. The shielding database also stores the shielding shadow areas corresponding to different shielding distances and shielding specifications.

[0159] Step S704: Determine the device area according to the device specification.

[0160] The device area refers to the area of ​​the multi-scenario partial discharge monitoring device, which is calculated by retrieving the corresponding dimensions from the device specifications and using the retrieved dimensions as the device area.

[0161] Step S705: Determine the tilt angle according to the device area and the shadow area.

[0162] The tilt angle refers to the tilt angle of the baffle on the shielding device. The tilt angle is matched from the shielding database by the device area and the shielding shadow area. The shielding database also stores the tilt angles corresponding to different device areas and shielding shadow areas, which will not be elaborated here.

[0163] Step S706: controlling the shielding device to tilt according to the tilt angle, and updating the ambient humidity value according to a preset unit time.

[0164] The shielding device is tilted by controlling the tilt angle, so that the sun can irradiate the surroundings of the multi-scenario partial discharge monitoring device to the maximum extent, and a new surrounding humidity value can be obtained per unit time.

[0165] Step S707: Calculate the difference between the ambient humidity values ​​before and after the update and use it as the humidity deviation value.

[0166] The humidity deviation value refers to the deviation value of the humidity around the multi-scenario partial discharge monitoring device within a unit time. The humidity deviation value is obtained by calculating the difference between the surrounding humidity values ​​before and after the update.

[0167] Step S708: Determine the humidity deviation speed according to the humidity deviation value and the unit time.

[0168] Humidity deviation speed refers to the speed at which the ambient humidity value changes. The humidity deviation speed is calculated by dividing the humidity deviation value by the unit time.

[0169] Step S709: When the humidity deviation speed is decreasing, continue to obtain the ambient humidity value.

[0170] When the humidity deviation rate is decreasing, it means that the humidity around the multi-scenario partial discharge monitoring device is decreasing due to solar radiation, so the surrounding humidity value continues to be obtained.

[0171] Step S710: when the humidity deviation speed is increasing, determining the blowing power according to the humidity deviation speed, and controlling the preset wind output device to blow air to the multi-scenario partial discharge monitoring device according to the blowing power.

[0172] When the humidity deviation speed is increasing, it means that the humidity around the multi-scenario partial discharge monitoring device is still increasing under the sun's irradiation. Therefore, the blowing power is matched from the preset blowing database through the humidity deviation speed, and the blowing power is output to the wind output device to blow the multi-scenario partial discharge monitoring device, so that the surrounding air of the multi-scenario partial discharge monitoring device can be circulated, and it is not easy for the multi-scenario partial discharge monitoring device to produce parameter deviation due to humidity, and it is not easy to produce judgment errors for abnormal conditions of the multi-scenario partial discharge monitoring device. The blowing power corresponding to different humidity deviation speeds is stored in the blowing database. The blowing database is a database set by humans and will not be described here.

[0173] Previous methods for determining blowing power include: Step S800: Determine whether the humidity deviation speed is less than a preset reference increasing speed.

[0174] The reference increment speed refers to the minimum speed of humidity increment corresponding to water drop splashing around the multi-scenario partial discharge monitoring device, which is set and stored in advance by the operator. By determining whether the humidity deviation speed is less than the reference increment speed, it is determined whether water drop splashing occurs around the multi-scenario partial discharge monitoring device.

[0175] Step S801: When the humidity deviation speed is less than the reference increasing speed, the blowing power continues to be output.

[0176] When the humidity deviation rate is less than the benchmark increasing rate, it indicates that no water droplets are splashing around the multi-scenario partial discharge monitoring device, so the blowing power continues to be output.

[0177] Step S802: When the humidity deviation speed is not less than the reference increasing speed, the humidity distribution position is determined according to the surrounding environment image and the preset humidity characteristics.

[0178] Humidity characteristics refer to the characteristics corresponding to water drop splashing, humidity and puddles. The humidity characteristics are set in advance by technicians in this field and will not be described here. The humidity distribution position refers to the position where water drop splashing occurs around the multi-scenario partial discharge monitoring device, when the humidity deviation rate is not less than the benchmark increment rate. It indicates that water drop splashing occurs around the multi-scenario partial discharge monitoring device, so the image corresponding to the humidity characteristics is selected through the surrounding environment image, and the position of the selected image in the surrounding environment image is used as the humidity distribution position.

[0179] Step S803: Determine a reference splash distance according to the humidity distribution position and the actual installation position.

[0180] The benchmark splash distance refers to the benchmark distance from water droplets splashing to the multi-scenario partial discharge monitoring device. The horizontal straight-line distance between the humidity distribution position and the actual installation position is calculated as the benchmark splash distance.

[0181] Step S804: determining a reference splashing arc according to a reference splashing distance.

[0182] The reference splash arc refers to the arc corresponding to the splash when the water drop splashes and moves the reference splash distance. The reference splash arc is matched from a preset water drop database through the reference splash distance. The water drop database stores reference splash arcs corresponding to different reference splash distances. The water drop database is a manually set database and will not be described in detail here.

[0183] Step S805: determining the splashing arc of the water drop according to the surrounding environment image and the preset water drop features.

[0184] The water droplet feature refers to the shape and other features corresponding to the water droplet, which are set and stored in advance by the operator. The water droplet splash arc refers to the actual splash arc formed when the water droplets splash at the humidity distribution position. The shape corresponding to the water droplet feature is selected by the surrounding environment image, and the direction corresponding to the selected shape is obtained to obtain the water droplet splash arc.

[0185] Step S806: When the water drop splashing arc is not greater than the reference splashing arc, continue to determine the water drop splashing arc.

[0186] When the water drop splashing arc is not greater than the reference splashing arc, it means that the water drop cannot splash onto the multi-scenario partial discharge monitoring device, so continue to determine the water drop splashing arc. Step S807: When the water drop splashing arc is greater than the reference splashing arc, the shielded splashing position is determined according to the humidity distribution position.

[0187] The shielding splash position refers to the position where the shielding device shields the splash of water droplets. When the water droplet splash arc is greater than the reference splash arc, it means that the water droplets can splash onto the multi-scenario local discharge monitoring device. Therefore, the straight-line distance between the humidity distribution position and the actual installation position is calculated, and the shielding splash position is matched from the shielding database through the straight-line distance. The shielding splash position corresponding to the straight-line distance between different humidity distribution positions and the actual installation positions is also stored in the shielding database, which will not be elaborated here.

[0188] Step S808: Determine the tilt adjustment angle according to the shielding splash position, the irradiation area and the actual installation position.

[0189] The tilt adjustment angle refers to the angle corresponding to the sunshade device in the splash shielding position after adjustment. The tilt adjustment angle is matched from the illumination database by the splash shielding position, the irradiation area and the actual installation position. The illumination database also stores the tilt adjustment angles corresponding to different splash shielding positions, irradiation areas and actual installation positions, which will not be elaborated here.

[0190] Step S809: adjusting the shielding device according to the tilt adjustment angle and the shielding splash position.

[0191] The shielding device is adjusted by outputting the tilt adjustment angle and the shielding splash position to the shielding device.
