[0027] Before introducing the technical solution of the embodiment of the present invention, an example description of the application scenario is given. The technical solution of the embodiment of the present invention can be applied to situations where it is necessary to calibrate the online monitoring device to ensure the normal operation of the online monitoring device. It can be understood that in the closed combination electrical system commonly used in the power grid, sulfur hexafluoride gas is used as the insulating medium, and a partial discharge online monitoring device can be used to monitor the partial discharge of sulfur hexafluoride gas, thereby ensuring the normal operation of the closed combination electrical system. Furthermore, in order to ensure the effectiveness of the partial discharge online monitoring device, the online monitoring device can be verified for effectiveness. The specific verification method can be to verify the partial discharge sensor in the online monitoring device. The present technical solution can automatically verify the effectiveness of the partial discharge sensor in the online monitoring device.

[0028] Example 1

[0029] Figure 1 A flowchart of a calibration method applied to an online monitoring device is provided for the first embodiment of the present invention. This embodiment is applicable to situations where calibration of an online monitoring device is required. The method can be executed by a calibration device applied to the online monitoring device. The calibration device can be implemented in the form of hardware and / or software. The calibration device can be configured in the online monitoring device and the server. Figure 1 As shown, the method includes:

[0030] S110 , upon receiving first data collected when an analog signal generator transmits an analog partial discharge signal at a first partial discharge sensor, obtaining a first partial discharge spectrum.

[0031] The analog signal generator may be a generator for emitting a simulated partial discharge signal, the simulated partial discharge signal may be a partial discharge signal simulated by the analog signal generator, and the partial discharge signal may typically be a pulse signal. The first partial discharge sensor refers to a sensor for acquiring the simulated partial discharge signal, and the first data may be signal data obtained by the first partial discharge sensor after acquiring and converting the simulated partial discharge signal. The first partial discharge spectrum may be understood as a spectrum for characterizing partial discharge.

[0032] Specifically, the analog signal generator can emit a simulated partial discharge signal at the position of the first partial discharge sensor. The first partial discharge sensor can collect the simulated partial discharge signal, and obtain first data corresponding to the simulated partial discharge signal by filtering and amplifying the simulated partial discharge signal. The first data is sent to the background system so that the background system can analyze and calculate the data, and then generate a first partial discharge map.

[0033] Based on the above technical solution, when receiving first data collected when the analog signal generator transmits a simulated partial discharge signal at the first partial discharge sensor, obtaining a first partial discharge spectrum includes: sending a control signal to an analog signal controller, so that the analog signal controller controls the analog signal generator to transmit the simulated partial discharge signal at the first partial discharge sensor based on the control signal.

[0034] The control signal may be a signal sent by a background system, and the analog signal controller may receive the signal so that the background system can remotely control the analog signal controller. The analog signal controller may be used to trigger the analog signal generator so that the analog signal generator emits a simulated partial discharge signal.

[0035] Specifically, to facilitate the calibration of the online monitoring device, communication between the backend system and the analog signal controller can be pre-established. For example, the communication method can be 5G communication or micro-power wireless communication, which allows the backend system to remotely control the analog signal controller. Specifically, the backend system can send a control signal to the analog signal controller, and the analog signal controller can trigger the analog signal generator based on the received control signal, thereby causing the analog signal generator to emit a simulated partial discharge signal at the first partial discharge sensor. The advantage of this is that the analog signal generator can be remotely controlled by the backend system, thereby achieving calibration of the online monitoring device, without the need for manual triggering of the analog signal generator.

[0036] S120 . When the analog signal generator transmits the analog partial discharge signal, the second partial discharge sensor collects the analog partial discharge signal, and when second data corresponding to the analog partial discharge signal is received, determines a second partial discharge spectrum.

[0037] Among them, the second partial discharge sensor can be understood as a sensor for collecting analog partial discharge signals, the second data can be signal data obtained after the second partial discharge sensor collects and converts the analog partial discharge signal at the first partial discharge sensor, the second partial discharge sensor and the first partial discharge sensor are arranged at different positions, and the second partial discharge spectrum can be understood as a spectrum used to characterize partial discharge.

[0038] Specifically, when a simulated partial discharge signal is emitted at the first partial discharge sensor, the simulated partial discharge signal can be collected by the second partial discharge sensor. After collecting the simulated partial discharge signal, the simulated partial discharge signal is processed, for example, filtered and amplified, to obtain second data corresponding to the simulated partial discharge signal, and the second data is sent to the background system so that the background system can analyze and calculate the data, thereby generating a second partial discharge map.

[0039] Based on the above technical solution, the analog signal generator is arranged at a position adjacent to the first partial discharge sensor and away from the second partial discharge sensor.

[0040] Specifically, the analog signal generator can be placed relatively close to the first PD sensor, for example, around the first PD sensor. Furthermore, the analog signal generator can be positioned relatively far from the second PD sensor. In this case, channel validity verification can be performed on the first PD sensor, and coverage verification can be performed on the second PD sensor.

[0041] In practical applications, analog signal generators can be pre-installed around each partial discharge sensor in a sulfur hexafluoride enclosed combination electrical appliance, or on the corresponding insulating basin. This allows multiple analog signal generators to be installed. This allows the analog signal generators around that partial discharge sensor or on the corresponding insulating basin to be controlled to emit a partial discharge signal when a simulated partial discharge signal is required at a particular partial discharge sensor. This arrangement offers the advantage of pre-installing a corresponding analog signal generator at each partial discharge sensor, allowing the corresponding analog signal generator to be remotely controlled to emit a partial discharge signal.

[0042] S130: Determine a target verification report based on the first partial discharge spectrum and the second partial discharge spectrum.

[0043] The target verification report may be understood as a verification report of an online monitoring device. The target verification report may be a document file, which includes verification details of the online monitoring device.

[0044] Specifically, the first partial discharge map and the second partial discharge map may be displayed on a display interface of the background system, and screenshots of the first partial discharge map and the second partial discharge map may be taken to generate a target verification report.

[0045] Based on the above technical solution, the first and second partial discharge maps include amplitude and phase information of the simulated partial discharge signal. The partial discharge maps contain the amplitude and phase of the partial discharge pulse signal. These information is typically used to determine the severity of partial discharge in a closed combination electrical system and whether the system requires repair, thereby preventing equipment failures and potential accidents.

[0046] On the basis of the above technical solution, determining the target verification report based on the first partial discharge spectrum and the second partial discharge spectrum includes: exporting the first partial discharge spectrum and the second partial discharge spectrum to generate the target verification report.

[0047] Specifically, the first partial discharge spectrum and the second partial discharge spectrum can be exported to a standardized file, or can be judged to be qualified according to the judgment standard of the partial discharge spectrum, thereby generating a verification report.

[0048] The technical solution of the embodiment of the present invention obtains a first partial discharge spectrum upon receiving first data collected when a simulated partial discharge signal is emitted at a first partial discharge sensor based on an analog signal generator; collects the simulated partial discharge signal based on a second partial discharge sensor when emitting the simulated partial discharge signal based on the analog signal generator, and determines a second partial discharge spectrum upon receiving second data corresponding to the simulated partial discharge signal; and determines a target verification report based on the first partial discharge spectrum and the second partial discharge spectrum. The technical solution of the present invention solves the problem of low efficiency of manual verification of online monitoring devices in the prior art by transmitting a simulated partial discharge signal at the first partial discharge sensor, detecting the simulated partial discharge signal based on the first partial discharge sensor and the second partial discharge sensor, respectively, and determining a verification report. It realizes automatic verification of the online monitoring device and improves the verification efficiency of the online monitoring device.

[0049] Example 2

[0050] Figure 2 This is a flowchart of a verification method for an online monitoring device, provided in Example 2 of the present invention. This example provides a detailed description of the channel validity verification of the first partial discharge sensor and the coverage verification of the second partial discharge sensor. For specific implementations, please refer to the technical solution of this example. Technical terms that are identical or corresponding to those in the previous examples are not repeated here.

[0051] like Figure 2 As shown, the method includes:

[0052] S210 : Upon receiving first data collected when an analog signal generator transmits an analog partial discharge signal at a first partial discharge sensor, obtaining a first partial discharge spectrum.

[0053] S220 . When the analog signal generator transmits the analog partial discharge signal, the second partial discharge sensor collects the analog partial discharge signal, and when second data corresponding to the analog partial discharge signal is received, determines a second partial discharge spectrum.

[0054] S230: Determine a channel validity verification result of the first partial discharge sensor based on the first partial discharge spectrum.

[0055] The channel validity check can be understood as checking the acquisition and transmission channels of the first partial discharge sensor to determine whether it can acquire the simulated partial discharge signal and send it to the background system after processing.

[0056] Based on the above technical solution, determining the channel validity verification result of the first partial discharge sensor based on the first partial discharge spectrum includes: detecting the analog partial discharge signal based on the first partial discharge sensor, and if first data corresponding to the analog partial discharge signal is received and a first partial discharge spectrum is generated based on the first data, determining that the channel validity verification of the first partial discharge sensor is successful.

[0057] Specifically, if the first PD sensor can normally detect the analog PD signal, processes the signal into first data, and transmits it to the backend system, and the backend system can normally receive the signal and generate a first PD spectrum based on the signal, this indicates that the channel verification of the first PD sensor is successful. It is understood that if the first PD sensor can normally detect the analog PD signal, and the corresponding backend system can also receive and process the signal sent by the first PD sensor in parallel, this indicates that the detection channel of the first PD sensor for the analog PD signal is normal, that is, the first PD sensor in the online monitoring device is capable of detecting PDs. This has the advantage of performing channel validity verification on the first PD sensor, ensuring that the first PD sensor can detect normally and avoiding detection errors or inability to detect.

[0058] S240: Determine a coverage verification result of the second partial discharge sensor based on the second partial discharge spectrum.

[0059] It should be noted that multiple partial discharge sensors are installed in enclosed combination electrical systems, and the enclosed combination electrical system contains a variety of electrical equipment. Normally, the partial discharge sensor at the current location can detect the electrical equipment at that location. However, if the sensor at the current location fails, a partial discharge in the electrical equipment at that location will not be detected, causing damage to the equipment and harm to the power grid, leading to power outages. Therefore, it is required that the partial discharge sensor at the current location can normally detect simulated partial discharge signals at other locations. In other words, even if the partial discharge sensors at other locations fail, the simulated partial discharge signals at other locations can still be detected by the partial discharge sensor at the current location.

[0060] The coverage verification can be understood as verifying the coverage of the PD sensor, that is, whether the PD sensor at the current position can detect the simulated PD signals at other positions.

[0061] Based on the above technical solution, determining the coverage verification result of the second partial discharge sensor based on the second partial discharge map includes: detecting the simulated partial discharge signal based on the second partial discharge sensor, and determining that the coverage verification of the second partial discharge sensor is successful if second data corresponding to the simulated partial discharge signal is received and a second partial discharge map is generated based on the second data.

[0062] Specifically, the second partial discharge sensor can be used to detect the simulated partial discharge signal at the first partial discharge sensor. If it can be detected and processed to obtain second data, the second data is sent to the background system so that the background system can generate a second partial discharge map based on the second data. This indicates that the coverage verification of the second partial discharge sensor is successful, that is, the second partial discharge sensor can normally detect the simulated partial discharge signal at the first partial discharge sensor.

[0063] S250: Determine a target verification report based on the channel validity verification result and the coverage verification result.

[0064] Specifically, after determining that the channel validity verification of the first partial discharge sensor is successful and the coverage verification of the second partial discharge sensor is successful, the corresponding first partial discharge map, second partial discharge map, channel validity verification results, and coverage verification results can be stored in a document as a target verification report.

[0065] In this embodiment, after the channel validity check of the first partial discharge sensor and the coverage check of the second partial discharge sensor, an analog partial discharge signal can be emitted at the position of the second partial discharge sensor, while no analog partial discharge signal is emitted at the first partial discharge sensor. Then, the above-mentioned method is used to perform the coverage check of the first partial discharge sensor and the channel validity check of the second partial discharge sensor.

[0066] In practical applications, this technical solution can not only perform coverage verification between two partial discharge sensors, but also between three or more partial discharge sensors. It is understandable that there are usually multiple partial discharge sensors contained in a closed combination electrical system, and the above method can be used to verify the channel validity of each partial discharge sensor. For the coverage verification of partial discharge sensors, since the analog partial discharge signal will attenuate with distance, when performing coverage verification on the current partial discharge sensor, the analog partial discharge signal can be emitted from multiple other partial discharge sensors within a certain range from the current partial discharge sensor. If the current partial discharge sensor can detect the analog partial discharge signal, it can be considered that the coverage verification of the current partial discharge sensor is successful.

[0067] For example, the distance range can be set to 5m or 8m. The current partial discharge sensor is partial discharge sensor A. In a closed combination electrical system, other partial discharge sensors less than 5m or 8m away from the location of partial discharge sensor A are partial discharge sensors B, C, and D. In this case, analog partial discharge signals can be emitted at the locations of partial discharge sensors B, C, and D. If partial discharge sensor A can detect analog partial discharge signals at all three locations, it can be considered that the coverage verification of partial discharge sensor A is successful. The technical solution of an embodiment of the present invention is to obtain a first partial discharge spectrum when receiving first data collected when an analog partial discharge signal is emitted at a first partial discharge sensor based on an analog signal generator; when the analog partial discharge signal is emitted based on the analog signal generator, the analog partial discharge signal is collected based on a second partial discharge sensor; and when second data corresponding to the analog partial discharge signal is received, a second partial discharge spectrum is determined; and a target verification report is determined based on the first partial discharge spectrum and the second partial discharge spectrum.

[0068] The technical solution of the present invention solves the problem of low efficiency of manual calibration of online monitoring devices in the prior art by transmitting a simulated partial discharge signal at a first partial discharge sensor, detecting the simulated partial discharge signal based on the first partial discharge sensor and the second partial discharge sensor, and determining a calibration report. It realizes automatic calibration of the online monitoring device and improves the calibration efficiency of the online monitoring device.
