Description

Technical Field

[0001] This invention relates to the field of substation equipment, and specifically to a method and device for measuring the potential of a protection pressure plate with automatic storage of potential data. Background Technology

[0002] Engaging and disengaging protection switches in substations is one of the most common secondary equipment switching operations performed by operators. Measuring the voltage potential across the protection switches before engagement ensures the correctness and safety of the circuit connections. For example, under normal conditions of a 220kV DC system in a substation, when a 220kV line circuit breaker is in the open position, the control circuit is normally energized. Using a DC voltmeter to measure the ground potential at the top of the protection trip outlet switch for that line, the correct value should be approximately +110V. If the ground potential is 0V or -110V, an error in the secondary circuit connection or a component failure can be detected in advance, avoiding the risk of equipment damage or malfunction after engaging the switch.

[0003] Currently, operators mainly use multimeters for potential measurement and verification. In actual work, there have been cases of misuse of multimeters, such as using the low internal resistance setting for measurement, which has caused accidental operation of switches. At the same time, due to the complex structure of the secondary circuit and the large number of protection devices in the station, each protection device has different types and numbers of pressure plates, which can easily lead to abnormal pressure plate potential measurement but failure to detect it in time.

[0004] The limited space and difficulty in recording video when operators engage the protection panel's terminal potential measurements make it impossible to track the measurement process afterward. If an anomaly is detected in the secondary circuit of the protection device after the terminal is engaged, it's impossible to trace whether the measured potential was normal when the operator engaged the terminal. This makes it difficult to determine whether the secondary circuit fault occurred before or after the terminal was engaged, hindering fault analysis, diagnosis, and accountability. Summary of the Invention

[0009] Preferably, the step of obtaining the platen potential operation result based on historical data and the potential data includes: After the platen engagement / disengagement operation, the historical potential measurement data is retrieved, and the data stored in the potential meter is combined with the platen engagement / disengagement operation steps and timing sequence on the operation ticket to obtain the platen potential operation result.

[0010] Preferably, the step of combining the data stored in the potentiometer with the platen engagement / disengagement operation steps and timing of the operation ticket to obtain the platen potential operation result includes: Compare the stored potential measurement data with the preset normal potential range of the corresponding step in the operation ticket; If the measurement data exceeds the preset range, it will be marked as abnormal, and the corresponding time, operation steps and deviation value will be recorded.

[0011] Preferably, the potential measurement history data includes measurement date, time, voltage type, and voltage value information.

[0012] To achieve this, the application also includes a protective pressure plate potential measuring device with automatic potential data storage, comprising: The measurement module is used to select the measurement mode and range of the potentiometer according to the properties and magnitude range of the potential of the protection plate.

[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The inventors, through analysis of existing technologies, discovered that the use of multimeters for measuring the potential of protection circuit breakers in current techniques presents several risks. Firstly, the multimeter's diverse functions pose a risk of incorrect range selection or incomplete switching, potentially leading to equipment malfunctions and other safety incidents. Secondly, the measurement process lacks effective data recording and traceability mechanisms. When an anomaly occurs in the secondary circuit, it becomes impossible to determine whether the fault occurred before or after the operation, significantly complicating troubleshooting and liability determination. These shortcomings severely impact the safety and reliability of switching operations on substation secondary equipment. Therefore, a method and device specifically designed for measuring the potential of protection circuit breakers with automatic data storage is needed to address these issues.

[0019] In the embodiments of this application, compared with the problems in the prior art such as incorrect multimeter range selection or incomplete conversion leading to malfunction of relay protection device output, false tripping of power supply or voltage air switch, and the inability to trace the measurement process, which is not conducive to fault analysis and accountability, this application provides a targeted solution. It eliminates the current and resistance measurement circuits and related ranges of the multimeter, retaining only the AC / DC voltage measurement function required for the pressure plate activation operation, thus avoiding problems such as incorrect range selection. Simultaneously, by installing a potential measurement data storage card and adding GPS automatic and manual time calibration functions, the potential data measured at different times is automatically stored, and the measurement can be traced back to determine if it was normal, combined with the operation ticket. Specifically: the measurement mode and range of the potentiometer are selected according to the attributes and magnitude range of the protection pressure plate potential; the potential to ground of each protection pressure plate is measured according to the pressure plate activation / deactivation operation steps and timing sequence in the operation ticket, and the potential data at at least three different times are automatically saved in the storage card; the pressure plate potential operation result is obtained based on historical data and the potential data. The potentiometer in this application eliminates redundant functions such as current and resistance measurement, retaining only the AC / DC voltage measurement function required for the protection plate potential measurement. From a hardware design perspective, this avoids accidents such as relay protection device malfunction and power switch tripping due to incorrect range selection or incomplete switching, significantly reducing operational risks and providing safer protection for substation secondary equipment switching operations. Accurate measurement time is ensured through GPS automatic or manual time synchronization, combined with a high-frequency storage mechanism of no less than 3 data points per second, allowing for complete recording of protection plate potential data at different times. When an anomaly occurs in the secondary circuit of the protection device, the stored data can be correlated with the steps and timing of the operation ticket for analysis, clearly tracing the potential changes before and after the operation, and identifying the time node of the fault occurrence. This facilitates rapid fault location and provides objective evidence for liability determination. The device can automatically match the appropriate measurement mode and range according to the voltage type and range of the circuit where the protection plate is located, effectively improving measurement accuracy. Simultaneously, data is stored in an encrypted format on a removable memory card, supporting export to a computer via USB or wirelessly. Combined with dedicated data management software, functions such as querying, filtering, and chart generation are realized, simplifying the data processing workflow.

[0020] Reference Figure 1 This document illustrates a flowchart of the steps involved in measuring the potential of a protective pressure plate with automatic potential data storage, according to an embodiment of this application. The steps specifically include the following: S110. Select the measurement mode and range of the potentiometer according to the properties and magnitude range of the protective plate potential; S120. Measure the ground potential of each protection plate according to the plate engagement / disengagement operation steps and timing of the operation ticket, and automatically save the potential data at at least 3 different times to the memory card. S130. Obtain the pressure plate potential operation result based on historical data and the potential data.

[0021] The following will further explain the protection plate potential measurement with automatic potential data storage function in this exemplary embodiment.

[0022] In one embodiment of the present invention, the specific process of "selecting the measurement mode and range of the potentiometer according to the properties and magnitude range of the protective pressure plate potential" in step S110 can be further explained in conjunction with the following description.

[0023] Step S110 specifically includes the following steps: calibrating the potentiometer time using the time calibration function; selecting the AC / DC voltage and voltage range of the potentiometer according to the properties and magnitude range of the protection plate potential.

[0024] In this embodiment, the potentiometer time detection function is activated and it is determined whether the work site has the conditions for automatic time synchronization. If so, the potentiometer time is corrected through GPS time synchronization function; the corresponding AC / DC measurement mode is selected according to the voltage type of the secondary circuit where the protection pressure plate is located; and the appropriate range is selected from multiple preset ranges according to the rated voltage value of the circuit.

[0025] In one specific embodiment, the potentiometer time detection function first checks the GPS signal strength. If the signal strength meets the time synchronization requirements (e.g., the signal strength is greater than a preset threshold), GPS time synchronization is automatically initiated to correct the potentiometer time to the standard time. If the GPS signal strength does not meet the requirements, the potentiometer will issue a prompt signal, and the operator can manually synchronize the time using the buttons on the potentiometer by inputting the current accurate time. Figure 5 As shown.

[0026] In one specific embodiment, the voltage type of the circuit where the protection pressure plate is located is first determined. If it is a DC circuit, the DC voltage measurement mode is selected; if it is an AC circuit, the AC voltage measurement mode is selected. Then, according to the rated voltage value of the circuit, for example, a 220V DC circuit selects a 250V DC range, and a 110V AC circuit selects a 250V AC range, to ensure that the measured value is within the appropriate range.

[0027] In the embodiments of this application, selecting an appropriate measurement mode and range based on the actual situation of the protective pressure plate can ensure the accuracy of the measurement data, avoid measurement errors or equipment damage caused by improper range, and provide a reliable basis for subsequent data analysis.

[0028] In one embodiment of the present invention, the specific process of step S120, which involves measuring the ground potential of each protection pressure plate according to the pressure plate activation / deactivation operation steps and timing sequence of the operation ticket, and automatically saving the potential data at at least three different times in the memory card; wherein the potential data stored per second is not less than three.

[0029] Step S120 includes: measuring the ground potential of each protection plate according to the plate engagement / disengagement operation steps and timing of the operation ticket, and automatically saving the potential data at different times to the memory card, with no less than 3 potential data stored per second.

[0030] In the embodiments of this application, measurements are performed and data is stored at high frequency according to the steps and timing of the operation ticket. This allows for a complete record of potential changes during the measurement process, providing detailed data support for subsequent traceability and avoiding traceability difficulties caused by missing data. Operators measure each protective pressure plate sequentially according to the order on the operation ticket, contacting the potentiometer's measuring probe with the pressure plate terminals. The potentiometer measures and displays the potential value in real time, simultaneously recording at least three data entries per second, including measurement time, voltage type, range, and measured value. These data are then encrypted and stored on a memory card to prevent unauthorized modification.

[0031] In one embodiment of the present invention, the specific process of "obtaining the pressure plate potential operation result based on historical data and the potential data" in step S130 can be further explained in conjunction with the following description.

[0032] Step S130 includes the following steps: after the platen engagement / disengagement operation, by searching the historical potential measurement data, the data stored in the potential meter is combined with the platen engagement / disengagement operation steps and timing of the operation ticket to obtain the platen potential operation result.

[0033] In this embodiment, the stored potential measurement data is compared with the preset normal potential range for the corresponding step in the operation ticket; if the measurement data exceeds the preset range, it is marked as abnormal, and the corresponding time, operation step, and deviation value are recorded. The potential measurement history data includes measurement date, time, voltage type, and voltage value information.

[0034] After the pressure plate is engaged or disengaged, check the historical potential measurement data on the potentiometer display screen, or import the historical potential measurement data from the potentiometer into the computer. Figure 3 As shown.

[0035] In the embodiments of this application, two data acquisition methods are provided: local viewing and computer export, which facilitates operators to view data in different scenarios. Local viewing allows for a quick understanding of the measurement overview, while computer export facilitates in-depth data analysis and archiving.

[0036] In one specific embodiment, after the search and export process is completed, the operator can use the potentiometer's operation buttons to search for historical measurement data on the display screen in chronological order or by pressure plate number. For detailed analysis, the potentiometer can be connected to a computer via USB cable, or the memory card can be removed, inserted into a card reader, and connected to a computer. The accompanying software can then be used to export the data as a spreadsheet or other file format. The data stored on the potentiometer is then combined with the pressure plate engagement / disengagement operation steps and timing on the operation ticket to confirm whether any abnormalities occurred during the previously performed pressure plate potentiometer operations.

[0037] In one specific embodiment, the exported measurement data is sorted by time and matched with the corresponding operation steps and time in the operation ticket. The measurement value of each step is compared with the preset normal potential range. If the measurement value is within the normal range, the operation of that step is determined to be normal; if it exceeds the range, it is marked as abnormal, and the time of the abnormality, the corresponding operation step, and the deviation of the measurement value from the normal range are recorded for subsequent analysis.

[0038] In the embodiments of this application, by analyzing the correlation between data and operation tickets, it is possible to accurately determine whether there is a potential abnormality during the operation, promptly detect potential faults, and clarify the time point of the fault occurrence, providing a basis for liability determination and improving the safety and management efficiency of substation operation.
