[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.

[0077] Optionally, the method before determining the blowing power includes:
[0078] Determine whether the humidity deviation speed is less than the preset reference increasing speed;
[0079] When the humidity deviation speed is less than the reference increasing speed, continue to output the blowing power;

[0103] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0104] Refer to Figure 1 This application embodiment discloses a multi-scenario partial discharge monitoring device, including a partial discharge sensor 2 for detecting partial discharge signals, a data transceiver device 3 for outputting the parameters detected by the partial discharge sensor to a server, and a magnetic attraction device for fixing the partial discharge sensor 2 to the device under test 1. The partial discharge sensor 2 is generally installed on the side wall of the preset device under test 1. The data transceiver device 3 can be an antenna.
[0105] Refer to Figure 2 This application embodiment discloses a multi-scenario partial discharge monitoring and warning method, including the following steps:
[0106] Step S100: Obtain the current detection value of the device under test 1 and the discharge fluctuation image of the multi-scenario partial discharge monitoring device.
[0107] The current detection value refers to the current parameter corresponding to the device under test 1 at the current time when partial discharge 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 obtained by the multi-scenario partial discharge monitoring device when detecting the device under test 1 during partial discharge. The image formed by the system by retrieving the parameters detected by the preset current sensor is used as the discharge fluctuation image. In this example, the device under test 1 can be a substation switchgear.
[0108] Step S101: When the current detection value is not greater than the preset reference current value, continue to obtain the current detection value.
[0109] The reference current value refers to the minimum current parameter corresponding to the device under test 1 when partial discharge occurs, which is formed by being pre-set and stored by the operator. When the current detection value is not greater than the reference current value, it indicates that no partial discharge has occurred in the device under test 1, so the current detection value is continuously obtained.
[0110] Step S102: When the current detection value is greater than the preset reference current value, calculate the difference between the current detection value and the reference current value as the current deviation value.
[0111] 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 has occurred in the device under test 1, so the difference between the current detection value and the reference current value is calculated as the current deviation value.
[0112] Step S103: Determine the current prediction amplitude according to the current deviation value.
[0113] The current prediction amplitude refers to the maximum fluctuation amplitude of the current fluctuation predicted by the multi-scenario partial discharge monitoring device when partial discharge occurs in the device under test 1. The current prediction amplitude is matched from the preset discharge database through the current deviation value. Different current deviation values and their corresponding current prediction amplitudes are stored in the discharge database, which is a database set by humans and will not be elaborated here.
[0114] Step S104: Retrieve the corresponding actual discharge amplitude from the discharge fluctuation image based on the current deviation value.
[0115] The actual discharge amplitude refers to the actual amplitude of the current fluctuation of the multi-scenario partial discharge monitoring device when partial discharge occurs in the device under test 1. The discharge arc corresponding to the time point of the current deviation value is retrieved from the discharge fluctuation image as the actual discharge amplitude.
[0116] Step S105: Determine whether the actual discharge amplitude is greater than the current estimated amplitude.
[0117] By determining whether the actual discharge amplitude is greater than the current estimated amplitude, it is determined whether the multi-scenario partial discharge monitoring device is abnormal.
[0118] Step S106: When the actual discharge amplitude is greater than the current estimated amplitude, output the preset alarm processing information.
[0119] When the actual discharge amplitude is greater than the current estimated amplitude, it indicates that partial discharge occurs in the device under test 1. Therefore, 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 partial discharge occurs in the device under test 1 and gives a warning, which is formed after being preset and stored by the operator.
[0120] Step S107: When the actual discharge amplitude is not greater than the current estimated amplitude, determine the actual fluctuation distance corresponding to the actual discharge amplitude according to the discharge fluctuation image.
[0121] 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 current estimated amplitude, it indicates that no partial discharge occurs in the device under test 1 and there is an abnormality in the multi-scenario partial discharge monitoring device. Therefore, the distance corresponding to the actual discharge amplitude is retrieved from the discharge fluctuation image in real time as the actual fluctuation distance.
[0122] 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.
[0123] The reference fluctuation distance refers to the maximum distance that the actual discharge amplitude is allowed to fluctuate, which is formed after being preset and stored by the operator. When the actual fluctuation distance does not exceed the reference fluctuation distance, it indicates that there is no need to output the preset alarm information. Therefore, continue to obtain the current detection value and the discharge fluctuation image. The alarm information refers to the prompt information that prompts the operator that there is an abnormality in the multi-scenario partial discharge monitoring device, which is formed after being preset and stored by the operator.
[0124] Step S109: When the actual fluctuation distance exceeds the preset reference fluctuation distance, output the preset alarm information.
[0125] When the actual fluctuation distance exceeds the reference fluctuation distance, it indicates that it is necessary to output the preset alarm information. Therefore, the alarm information is output to the terminal held by the operator, so as to be able to give an early warning prompt for the abnormality of the multi-scenario partial discharge monitoring device, timely process the abnormality of the multi-scenario partial discharge monitoring device, and be able to process the phenomenon of partial discharge.
[0126] It also includes a method before outputting a preset warning message:
[0127] Step S200: Obtain the image detection information of the multi-scenario partial discharge monitoring device.
[0128] 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 a camera preset around the device under test 1, and the photographed image is used as the image detection information.
[0129] Step S201: Determine the actual installation position according to the image detection information and the preset discharge device characteristics.
[0130] The discharge device characteristics refer to the shape and color of the multi-scenario partial discharge monitoring device. The actual installation position refers to the position where the multi-scenario partial discharge monitoring device is actually installed. By selecting the image corresponding to the discharge device characteristics from the image detection information, and obtaining the position corresponding to the selected image from the image detection information as the actual installation position.
[0131] Step S202: Determine whether the actual installation position falls within the preset reference installation range.
[0132] The reference installation range refers to the reference range corresponding to the installation of the multi-scenario partial discharge monitoring device for detecting the partial discharge situation of the device under test 1, which is formed by being preset and stored by the operator. By determining whether the actual installation position falls within the reference installation range, it is thus determined whether there is a parameter detection error due to position deviation in the multi-scenario partial discharge monitoring device.
[0133] Step S203: When the actual installation position falls within the reference installation range, continue to output the preset warning processing information.
[0134] When the actual installation position falls within the reference installation range, it indicates that there is no parameter detection error due to position deviation in the multi-scenario partial discharge monitoring device. Therefore, continue to output the warning processing information to the terminal held by the operator to facilitate the operator to handle the situation of partial discharge of the device under test 1.
[0135] Step S204: When the actual installation position does not fall within the reference installation range, calculate the minimum distance between the actual installation position and the reference installation range to determine the reset vector distance.
[0136] The reset vector distance refers to the vector distance when the multi-scenario partial discharge monitoring device is reset to the reference installation range. When the actual installation position does not fall within the reference installation range, it indicates that there is a situation where 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.
[0137] Step S205: Control the multi-scenario partial discharge monitoring device to reset according to the reset vector distance through a preset reset method.
[0138] The reset method refers to the method of controlling the multi-scenario partial discharge monitoring device to reset. The specific steps of the reset method refer to Step S300 to Step S405. By using the reset vector distance to control the multi-scenario partial discharge monitoring device to reset through the reset method, it is possible to prevent the multi-scenario partial discharge monitoring device from having parameter detection errors due to position offset.
[0139] The preset reset method includes:
[0140] Step S300: Obtain the device specifications of the multi-scenario partial discharge monitoring device.
[0141] The device specifications refer to the parameter specifications such as the size and weight of the multi-scenario partial discharge monitoring device. The corresponding size and weight parameter specifications of the multi-scenario partial discharge monitoring device are retrieved through the system as the device specifications.
[0142] Step S301: Retrieve the reference weight value according to the device specifications.
[0143] The reference weight value refers to the weight value of the multi-scenario partial discharge monitoring device. The weight parameter is retrieved from the device specifications as the reference weight value.
[0144] Step S302: Determine the magnetic force adjustment power according to the reference weight value.
[0145] The magnetic force adjustment power refers to the power of the magnetic attraction device on the multi-scenario partial discharge monitoring device after adjustment. The magnetic force adjustment power is matched from the preset magnetic force database through the reference weight value. Different magnetic force adjustment powers corresponding to different reference weight values are stored in the magnetic force database, which is a database set by humans and will not be elaborated here. The magnetic attraction device is a device used to install the multi-scenario partial discharge monitoring device on the side wall of the device to be measured. The magnetic attraction device can adjust the magnitude of the magnetic force by adjusting the current.
[0146] 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.
[0147] The vertical moving distance refers to the vertical straight-line distance between the multi-scenario partial discharge monitoring device and the ground. The straight-line distance between the actual installation position and the preset ground position is calculated 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 formed after being preset and stored by the operator.
[0148] Step S304: Determine whether the reset vector distance is positive.
[0149] By determining whether the reset vector distance is positive, it is determined whether the multi-scenario partial discharge monitoring device moves upward or downward.
[0150] Step S305: When the reset vector distance is positive and the vertical moving distance intersects with the reference installation range, determine each intersection point according to the vertical moving distance and the reference installation range, and define the intersection point closest to the actual installation position as the selected intersection point.
[0151] The selected intersection point refers to the intersection point on the reference installation range where the multi-scenario partial discharge monitoring device vertically moves to. When the reset vector distance is positive and the vertical moving distance intersects with the reference installation range, it indicates that the multi-scenario partial discharge monitoring device needs to vertically move downward. Therefore, the intersection point between the vertical moving distance and the reference 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.
[0152] Step S306: Determine the selected moving distance according to the selected intersection point and the vertical moving distance.
[0153] The selected moving distance refers to the moving distance when the multi-scenario partial discharge monitoring device vertically moves to the selected intersection point. 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.
[0154] Step S307: Adjust the power output according to the magnetic force to the magnetic attraction device preset on the multi-scenario partial discharge monitoring device to control the movement. When the actual installation position coincides with the selected intersection point, output the preset reference power to the magnetic attraction device.
[0155] By controlling the magnetic attraction device to adjust the power operation according to the magnetic force, the multi-scenario partial discharge monitoring device can vertically slide downward the selected moving distance on the device under test 1 by its own weight. And when the actual installation position coincides with the selected intersection point, it indicates that the multi-scenario partial discharge monitoring device moves into the reference installation range. Therefore, the preset reference power is output to the magnetic attraction device to fix the multi-scenario partial discharge monitoring device. The reference power refers to the reference power corresponding to the magnetic attraction device when fixing the multi-scenario partial discharge monitoring device, which is formed after being preset and stored by the operator.
[0156] The preset reset method further includes:
[0157] Step S400: If the reset vector distance is not a positive value, determine the air suction power according to the reference weight value and the reference power.
[0158] The air suction power refers to the power of the wind force output device for air suction. When the reset vector distance is not a positive value, it indicates that the multi-scenario partial discharge monitoring device needs to move upward. Calculate the air suction force through the reference weight value, and match the air suction power from the preset air suction database according to the air suction force. The wind force output device refers to the device installed on the device to be measured 1 and capable of air suction or blowing, and the wind force output device can move horizontally.

And when the running time of the wind power output device reaches the moving time, it indicates that the multi-scenario partial discharge monitoring device is within the reference installation range. Therefore, the wind power output device is controlled to stop running, so that it is not easy for the multi-scenario partial discharge monitoring device to have parameter detection errors due to position deviation.
[0166] The method after controlling the wind power output device to stop running includes:
[0167] Step S500: Obtain the surrounding environment image of the multi-scenario partial discharge monitoring device.
[0168] The surrounding environment image refers to the image around the multi-scenario partial discharge monitoring device. The image around the multi-scenario partial discharge monitoring device is captured by a camera preset on the device to be measured 1 as the surrounding environment image.

[0176] The reference safety distance refers to the minimum distance that can be tolerated 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 elaborated here. By determining whether the interval distance is less than the reference safety distance, it is determined whether there is a situation where a non-related person collides with the multi-scenario partial discharge monitoring device, resulting in a position offset and parameter detection error.

[0180] The portrait database refers to a database that stores the person detection information corresponding to relevant personnel. The portrait database is set in advance by those skilled in the art and will not be elaborated here.
[0181] When the person detection information is entered into the portrait database, it indicates that there is no situation where a non-related person collides with the multi-scenario partial discharge monitoring device, resulting in a position offset and parameter detection error. Therefore, continue to determine the person detection image. When the person detection information is not entered into the portrait database, it indicates that there is a situation where a non-related person collides with the multi-scenario partial discharge monitoring device, resulting in a position offset and parameter detection error. Therefore, control the preset shielding device to shield the multi-scenario partial discharge monitoring device according to the person's position until the person detection information does not appear in the surrounding environment image. The shielding device refers to a device that is set on the device to be measured 1 and is used to protect the multi-scenario partial discharge monitoring device from being easily collided, resulting in position offset, direct sunlight, humidity and other abnormal situations.

[0187] The reference moving direction refers to the direction perpendicular to the direction corresponding to approaching the multi-scenario partial discharge monitoring device, and is formed by being preset and stored by the operator in advance. When the person's moving direction is the reference moving direction, it indicates that there is no situation where non-related personnel collide with the multi-scenario partial discharge monitoring device, causing position deviation and resulting in parameter detection errors. Therefore, continue to determine the person position.
[0188] Step S510: When the person's moving direction is not the preset reference moving direction, determine the person's vector moving distance based on the person shapes before and after the update.
[0189] The person's vector moving distance refers to the vector distance corresponding to when the person moves. When the person's moving direction is not the reference moving direction, it indicates that there is a situation where non-related personnel collide with the multi-scenario partial discharge monitoring device, causing position deviation and resulting in parameter detection errors. Therefore, by calculating the quotient of the size parameters corresponding to the person shapes before and after the update, and taking the product of the calculated quotient value and the interval distance as the person's vector moving distance.
[0190] Step S511: Update the person's moving direction based on the person's vector moving distance.
[0191] By retrieving the corresponding direction parameter from the person's vector moving distance as the new person's moving direction.
[0192] Step S512: Output the preset prompt information based on the updated person's moving direction, and after the unit time, control the shielding device to perform shielding according to the updated person position until no person detection information appears in the surrounding environment image.
[0193] The prompt information refers to the information that prompts a person to stay away from the multi-scenario partial discharge monitoring device. When the updated person shape is smaller than the previous one, it indicates that the person is moving away from the multi-scenario partial discharge monitoring device. Therefore, continue to determine the person detection image. When the updated person shape is larger than the previous one, it indicates that the person is moving closer to the multi-scenario partial discharge monitoring device. Therefore, output the prompt information 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.
[0194] Further, the method after determining the person's position and shape includes:

[0203] 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.
[0204] When the discharge deviation parameter is consistent with the interference deviation parameter, it indicates 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. Therefore, continue to obtain the current detection value and the discharge fluctuation image.
[0205] Step S5026: When the discharge deviation parameter is inconsistent with the interference deviation parameter, calculate the difference between the discharge deviation parameter and the interference deviation parameter as the discharge deviation value.
[0206] 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 indicates that the interference device does not interfere with the multi-scenario partial discharge monitoring device and the multi-scenario partial discharge monitoring device has an abnormality. Therefore, calculate the difference between the discharge deviation parameter and the interference deviation parameter as the discharge deviation value.
[0207] Step S5027: Determine whether the discharge deviation value falls within the preset reference discharge deviation range.
[0208] The reference discharge deviation range refers to the allowable change range of the deviation parameter corresponding to when the interference device interferes with the multi-scenario partial discharge monitoring device. The reference discharge deviation range is formed by being preset and stored by the operator in advance.
[0209] Step S5028: When the discharge deviation value falls within the reference discharge deviation range, continue to obtain the current detection value and the discharge fluctuation image.
[0210] When the discharge deviation value falls within the reference discharge deviation range, it indicates that the change situation of the discharge deviation value is within the allowable range. Therefore, continue to obtain the current detection value and the discharge fluctuation image.
[0211] Step S5029: When the discharge deviation value does not fall within the reference discharge deviation range, output the preset warning information.
[0212] When the discharge deviation value does not fall within the reference discharge deviation range, it indicates that the change situation of the discharge deviation value is not within the allowable range. Therefore, output the preset warning information to the operator's terminal, so that the multi-scenario partial discharge monitoring device can know the abnormal situation of the multi-scenario partial discharge monitoring device when being interfered, and then can timely handle the abnormal situation of the multi-scenario partial discharge monitoring device.

Different correction coefficients corresponding to different irradiation distances are also stored in the irradiation database and will not be elaborated here.
[0224] Step S605: When the actual installation position does not fall within the irradiation area, continue to determine the irradiation area.
[0225] When the actual installation position does not fall within the irradiation area, it indicates that the sun does not shine on the multi-scenario partial discharge monitoring device, so continue to determine the irradiation area.

[0227] 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 within the irradiation area, it indicates that the sun shines on the multi-scenario partial discharge monitoring device, so the parameter detected by the temperature sensor preset on the multi-scenario partial discharge monitoring device is used as the actual temperature value.

[0229] The reference temperature value refers to the minimum temperature value when the multi-scenario partial discharge monitoring device has parameter deviation.

[0231] 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 indicates that the multi-scenario partial discharge monitoring device will have the situation of parameter deviation due to temperature, so match the shielding position from the preset shielding database according to the irradiation area and the actual installation position. Different irradiation areas and corresponding shielding positions of the actual installation positions are stored in the shielding database, and the shielding database is a database set by humans and will not be elaborated here.
[0232] Step S609: Control the preset shielding device to perform shielding according to the shielding position.

[0236] The ambient humidity value refers to the humidity value around the multi-scenario partial discharge monitoring device. The parameters around the multi-scenario partial discharge monitoring device are detected by a humidity sensor preset on the device to be measured 1 as the ambient humidity value.
[0237] Step S701: When the ambient humidity value is not greater than the preset reference humidity value, continue to obtain the ambient humidity value.
[0238] The reference humidity value refers to the minimum humidity value when the multi-scenario partial discharge monitoring device has parameter deviations. The reference humidity value is set in advance by those skilled in the art and will not be elaborated here. When the ambient humidity value is not greater than the reference humidity value, it indicates that the multi-scenario partial discharge monitoring device will not have parameter deviations due to humidity, so continue to obtain the ambient humidity value.

[0240] The occlusion distance refers to the distance of occlusion by the occlusion device. When the ambient humidity value is greater than the reference humidity value, it indicates that the multi-scenario partial discharge monitoring device will have parameter deviations due to humidity, so calculate the straight-line distance between the occlusion position and the actual installation position as the occlusion distance.

[0252] The humidity deviation speed refers to the speed at which the surrounding humidity value changes, and is calculated by taking the quotient of the humidity deviation value and the unit time as the humidity deviation speed.
[0253] Step S709: When the humidity deviation speed is decreasing, continue to obtain the surrounding humidity value.
[0254] When the humidity deviation speed is decreasing, it indicates that the humidity around the multi-scenario partial discharge monitoring device is decreasing due to the sun's irradiation, so continue to obtain the surrounding humidity value.
[0255] Step S710: When the humidity deviation speed is increasing, determine the blowing power according to the humidity deviation speed, and control the preset wind power output device to blow air on the multi-scenario partial discharge monitoring device according to the blowing power.
[0256] When the humidity deviation speed is increasing, it indicates 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 according to the humidity deviation speed, and the blowing power is output to the wind power output device to blow air on the multi-scenario partial discharge monitoring device, so that the air around the multi-scenario partial discharge monitoring device can circulate, and it is not easy for the multi-scenario partial discharge monitoring device to generate parameter deviation due to humidity, and it is not easy to generate a judgment error for the abnormal situation of the multi-scenario partial discharge monitoring device. The blowing database stores the blowing powers corresponding to different humidity deviation speeds. The blowing database is a database set by humans and will not be elaborated here.

[0270] Step S806: When the water droplet splash arc is not greater than the reference splash arc, continue to determine the water droplet splash arc.
[0271] When the water droplet splash arc is not greater than the reference splash arc, it indicates that the water droplet cannot splash onto the multi-scenario partial discharge monitoring device, so continue to determine the water droplet splash arc.
[0272] Step S807: When the water droplet splash arc is greater than the reference splash arc, determine the shielding splash position according to the humidity distribution position.
[0273] The shielding splash position refers to the position where the shielding device shields the water droplet splash. When the water droplet splash arc is greater than the reference splash arc, it indicates that the water droplet can splash onto the multi-scenario partial discharge monitoring device.
