Description

Technical Field

[0002] In the power system, the use of gas-filled equipment is increasing, especially the sulfur hexafluoride electrical equipment in gas-insulated metal-enclosed switchgear. The insulating gas sulfur hexafluoride can ensure the insulation strength between the circuit breaker, disconnector, earthing switch, current transformer, lightning arrester, busbar, connection parts, and outgoing terminal of the electrical equipment and the outer shell or the equipment break point. Currently, a sulfur hexafluoride pointer-type meter is equipped on the gas-insulated metal-enclosed switchgear to monitor the sulfur hexafluoride pressure in the equipment gas chamber. Since the sulfur hexafluoride electrical equipment often has a reduced air pressure due to leakage or temperature change during operation, the mechanical contacts on the pressure gauge are used to connect the secondary circuit to send out alarm and interlock operation signals, and the equipment operation and maintenance personnel need to regularly patrol and maintain the equipment to check whether the meter pressure is normal. However, it is difficult to timely determine the gas leakage of the sulfur hexafluoride electrical equipment through periodic patrol and maintenance. Especially when the leakage point on the equipment is small or the seal is not tight, resulting in slow gas leakage, and limited by reasons such as power outage windows, only the patrol and maintenance frequency can be increased and gas replenishment can be carried out regularly to maintain the operation of the equipment, which increases the workload of the operation and maintenance personnel.

[0044] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0045] Figure 1A A structural schematic diagram of the monitoring device provided by an embodiment of the present invention is shown as Figure 1A shown. The monitoring device includes: a flip cover 100, a corner measurement component 200, a temperature sensor 300, and a stirrup 400. The induction chip 201 of the corner measurement component 200 is attached to the surface of the flip cover 100, and the magnetized thin sheet 202 of the corner measurement component 200 is attached to the pointer of the meter. The temperature sensor 300 is attached to the surface of the flip cover 100, and the stirrup 400 fixes the flip cover 100 directly above the meter, so that the meter is installed inside the monitoring device.

[0046] In specific implementation, when the pointer of the meter rotates, it drives the magnetized thin sheet in the corner measurement component to rotate, so that the magnetic field between the magnetized thin sheet and the induction chip changes. The induction chip generates an angular electrical signal according to the magnetic field change, and data processing and data conversion are performed according to the angular electrical signal, so as to obtain the position of the meter pointer after the magnetic field changes. According to the position of the meter pointer after the magnetic field changes, the current air pressure value of the inflation device monitored by the meter can be automatically and timely monitored.

[0047] In an embodiment of the present invention, the monitoring device can perform real-time monitoring on the meter. It can be determined whether to install a monitoring device for each meter according to the budget cost, or a monitoring device can be installed on the meter with more air leakage phenomena detected. The monitoring device does not affect the monitoring of the meter by the operation and maintenance personnel. When the operation and maintenance personnel query the meter, the flip cover can be flipped up, and the air pressure value can be directly read through the viewing surface of the meter. When automatic monitoring is performed, the flip cover can be closed, and the induction chip and the magnetized thin sheet are placed in parallel to form a corner measurement component, and the air pressure value corresponding to the meter is automatically measured.

[0048] Figure 1B A structural schematic diagram of the meter provided by an embodiment of the present invention is shown as Figure 1B shown. The meter 500 includes a dial 501 and a pointer 502. When the meter 500 is installed inside the monitoring device, the monitoring device needs to be buckled above the dial 502 side of the meter 500 and fixed directly above the meter 500 by using a stirrup.

[0049] In an embodiment of the present invention, without affecting the induction sensitivity between the induction chip and the magnetized thin sheet, and without affecting the accuracy of the angular electrical signal generated by the induction chip, the induction chip can be embedded inside the flip cover entity, or on the side of the flip cover facing the viewing surface of the meter, and an integrated communication device can be installed at the original place of the induction chip to improve the signal transmission efficiency and accuracy. Among them, two sets of devices can be designed in the communication device to add a watchdog circuit to prevent the device from crashing and mis-sending signals. The communication device can also directly transmit the collected data using the Internet of Things SIM card signal.

[0050] Figure 2This is a schematic flowchart of a monitoring method for a meter provided by an embodiment of the present invention. This method can be executed by the monitoring device for the meter provided by the embodiment of the present invention, and the device can be implemented in a software and / or hardware manner. In a specific embodiment, the device can be integrated in an electronic device, such as a server. The following embodiments will be described by taking the integration of the device in the electronic device as an example. Referring to FIG. 1, the method can specifically include the following steps:

[0051] S210. Obtain the static position of the pointer, determine the rotation angle of the pointer through the magnetization sheet and the induction chip, and determine the measured air pressure value of the meter according to the static position and the rotation angle;

[0052] Exemplarily, the static position of the pointer can be the position where the pointer of the meter is located before obtaining the rotation angle by using the magnetization sheet and the induction chip. Among them, the static position of the pointer can be the position of the pointer updated by the last maintenance personnel as the static position of the pointer, or the position of the pointer without an angle signal after the monitoring device is installed as the static position of the pointer. The acquisition method of the static position of the pointer can be obtained by collecting an image on the side of the pointer of the meter and determining it according to the image, or can be directly read by the maintenance personnel, or after installing the monitoring device, uniformly obtain the static position of the pointer starting from a fixed position of the meter. The magnetization sheet can be a sheet with electromagnetic effects obtained after the magnetic medium is magnetized under the action of an external magnetic field, which can cause a magnetic field change when the meter needle rotates, so that the induction chip generates an electrical signal to facilitate the determination of the rotation angle of the pointer. The induction chip can be a chip that monitors the magnetic field change of the magnetization sheet, and can generate an angular electrical signal according to the magnetic field change caused by the rotation change of the magnetization sheet for determining the rotation angle of the pointer. The rotation angle of the pointer can be the angle at which the pointer of the meter rotates on the dial, used to quantify how much the pointer of the meter moves on the dial. Among them, the rotation angle of the pointer can be a negative value or a positive value, that is, the pointer of the meter can rotate forward or reverse. The measured air pressure value of the meter can be the current air pressure value corresponding to the position where the pointer of the meter stays after the rotation angle, that is, the air pressure value of the inflation device corresponding to the rotated pointer.

[0053] In a specific implementation, after installing a monitoring device on the meter, a magnetized thin sheet is fixed on the pointer of the meter. Before using the monitoring device to monitor the meter, the static position of the pointer of the meter is obtained. After obtaining the static position of the pointer of the meter, the monitoring device is used to start monitoring the change of the pointer of the meter, and the position change of the pointer in the meter is determined in real time through the magnetized thin sheet and the induction chip in the monitoring device. The current position of the pointer is determined by using the static position of the pointer and the rotation angle of the pointer determined through the magnetized thin sheet and the induction chip, and the measured air pressure value of the meter is determined by using the current position of the pointer, so as to use the monitoring device to monitor the numerical change on the meter in real time and avoid the increase in the workload of maintenance personnel after power failure and locking caused by untimely reading of the numerical change.

[0054] S220. Obtain the temperature in the area where the meter is located by using a temperature sensor, and determine the standard air pressure value corresponding to the meter according to the temperature in the area;

[0055] Exemplarily, the temperature sensor can be a device that converts temperature into an output signal that can be used by using the laws of various physical properties of substances changing with temperature. Among them, the temperature sensor in the monitoring device is used to obtain the temperature in the area where the meter is located, that is, to collect the ambient temperature at the site where the meter is located. Since the ambient temperature where the gas charging device is located has a great influence on the air pressure value of the gas charging device, it is necessary to comprehensively judge whether the air pressure value of the gas charging device is normal according to the ambient temperature. The temperature in the area can be the ambient temperature at the site where the meter is located, generally the surface temperature of the meter. The standard air pressure value corresponding to the meter can be the air pressure value of the gas charging device in a normal situation corresponding to the ambient temperature where the gas charging device is located, and is used to judge whether the air pressure value measured by the meter for the gas charging device is normal.

[0056] In a specific implementation, the current position of the pointer is determined by using the static position of the pointer and the rotation angle of the pointer determined through the magnetized thin sheet and the induction chip, and the measured air pressure value of the meter is determined by using the current position of the pointer. At the same time, the temperature in the area where the meter is located is obtained by using the temperature sensor in the monitoring device, the standard air pressure value corresponding to the temperature in the area is determined by looking up the standard air pressure comparison table by using the temperature in the area, and the standard air pressure value corresponding to the temperature in the area is used as the standard air pressure value corresponding to the meter. The standard air pressure value corresponding to the meter can be compared with the measured air pressure value of the meter to determine whether the gas charging device measured by the meter has a leak.

[0057] S230. Determine whether the gas charging device measured by the meter has a leak according to the standard air pressure value and the measured air pressure value;

[0058] In specific implementation, the gas-filled equipment measured by the meter can be a gas-insulated metal-enclosed switchgear, such as a sulfur hexafluoride electrical equipment, which uses the insulating gas sulfur hexafluoride to ensure the insulation strength between the circuit breaker, disconnector, earthing switch, instrument transformer, lightning arrester, busbar, connecting piece and outgoing terminal of the electrical equipment and the outer shell or the equipment break point. Among them, when the gas in the gas-filled equipment leaks, the insulation effect of the gas-filled equipment will decrease. It is necessary to monitor the gas-filled equipment through the meter in real time and compare the standard air pressure value with the measured air pressure value to determine whether the gas-filled equipment measured by the meter leaks. It can be by comparing the standard air pressure value with the measured air pressure value. If the standard air pressure value is greater than the measured air pressure value, it means that the gas-filled equipment measured by the meter leaks. If the standard air pressure value is less than or equal to the measured air pressure value, it means that the gas-filled equipment measured by the meter does not leak.

[0059] S240. When the gas-filled equipment measured by the meter leaks, determine the maintenance time according to the daily variation curve and the measured air pressure value.

[0060] In specific implementation, the daily variation curve can be a variation curve drawn based on the air pressure data and time of the historical charging equipment determined according to the measured air pressure value, which is used to determine the variation trend and daily variation value of the air pressure of the charging equipment, and can use the variation trend and daily variation value to predict the time required for the measured air pressure value to reach the locking threshold. Among them, the locking threshold can be the critical value of the air pressure corresponding to the automatic power-off or stop of work of the charging equipment, which is used to protect the charging equipment from equipment damage caused by the decrease in air pressure. The maintenance time can be the time point or date of maintenance by the maintenance personnel before locking, that is, the final deadline for maintenance. When it is determined that the gas-filled equipment measured by the meter leaks according to the comparison between the standard air pressure value and the measured air pressure value, obtain the air pressure data of the historical charging equipment according to the measured air pressure value, and draw a daily variation curve according to the measured air pressure value and the air pressure data of the historical charging equipment. Use the variation trend and daily variation value corresponding to the daily variation curve to predict the time required for the measured air pressure value to reach the locking threshold, and determine the maintenance time according to this time and the date corresponding to the measured air pressure value, so as to maintain the normal operation of the gas-filled equipment, formulate an accurate maintenance schedule, reduce the patrol frequency of operation and maintenance personnel, and improve work efficiency.

[0061] In an embodiment of the present invention, by obtaining the static position of the pointer and determining the rotation angle of the pointer through the magnetized sheet and the induction chip, the measured air pressure value of the meter is determined according to the static position and the rotation angle; the temperature in the area where the meter is located is obtained by using the temperature sensor, and the standard air pressure value corresponding to the meter is determined according to the temperature in the area; whether the inflatable device measured by the meter leaks is determined according to the standard air pressure value and the measured air pressure value; when the inflatable device measured by the meter leaks, the maintenance time is determined according to the daily variation curve and the measured air pressure value. That is, in the embodiment of the present invention, by installing the meter in the monitoring device, when the pointer rotates, the rotation angle of the pointer can be obtained in time to determine the measured air pressure value of the meter, the meter is monitored without the participation of maintenance personnel, and whether the inflatable device leaks can be determined by using the correspondence between the temperature and the air pressure value, reducing the workload of the maintenance personnel. At the same time, the maintenance time can be determined according to the daily variation curve to formulate an accurate maintenance plan, relieve the maintenance pressure, and improve the maintenance efficiency.

[0062] The monitoring method of the meter provided by the embodiment of the present invention is further described below. As Figure 3 shown, the method may specifically include the following steps:

[0063] S310. Obtain the static position of the pointer, determine the rotation angle of the pointer through the magnetized sheet and the induction chip, and determine the measured air pressure value of the meter according to the static position and the rotation angle;

[0064] Further, the induction chip is placed parallel to the magnetized sheet through the flip cover. Determining the rotation angle of the pointer through the magnetized sheet and the induction chip includes:

[0065] When the pointer drives the magnetized sheet to rotate, an angular electrical signal is obtained, and the angular electrical signal is generated by the induction chip according to the magnetic field change caused by the rotation of the magnetized sheet;

[0066] Determine the rotation angle of the pointer according to the angular electrical signal.

[0067] In specific implementation, the angular electrical signal may be an electrical signal generated by the induction chip according to the magnetic field change caused by the rotation of the magnetized sheet driven by the pointer rotation, and is used to represent the magnitude of the rotation angle of the pointer of the meter. Among them, the larger the angle through which the pointer drives the magnetized sheet to rotate, the greater the magnetization change generated by the rotation of the magnetized sheet, and the stronger the angular electrical signal sensed by the induction chip. Therefore, the corresponding relationship between the angular electrical signal and the rotation angle can be used to determine the rotation angle of the pointer of the meter according to the angular electrical signal.

[0068] Further, determining the measured air pressure value of the meter according to the static position and the rotation angle includes:

[0069] Determine the current position of the pointer according to the static position and the rotation angle of the pointer;

[0070] Determine the measured air pressure value of the meter according to the current position of the pointer.

[0071] In a specific implementation, the current position of the pointer can be the position where the pointer of the meter reaches after rotating from the static position, and is used to determine the measured air pressure value of the current meter according to the current position of the pointer. Determine the current position of the pointer by using the static position of the pointer and the rotation angle of the pointer determined by the magnetized thin sheet and the induction chip, and use the current position of the pointer to determine the measured air pressure value of the meter, so as to facilitate the real-time monitoring of the numerical changes on the meter by the monitoring device and avoid the increase in the workload of the maintenance personnel after power outage and locking caused by the failure to read the numerical changes in time.

[0072] Furthermore, determining the measured air pressure value of the meter according to the current position of the pointer includes:

[0073] Query the air pressure comparison table according to the current position of the pointer to determine the measured air pressure value of the meter;

[0074] Or, determine the model of the meter, and determine the measured air pressure value of the meter according to the model of the meter and the current position of the pointer.

[0075] In a specific implementation, the air pressure comparison table can be a standard comparison table formulated according to the reading data corresponding to the scales on the dial and the air pressure value, and is used to determine the measured air pressure value of the meter according to the current position of the pointer. The model of the meter can be the type number of different types of meters manufactured by different manufacturers. Different manufacturers manufacture meters with different sizes and accuracies according to different installed and measured devices. It is necessary to jointly determine the measured air pressure value of the meter by combining the model of the meter, the accuracy corresponding to each model, and the current position of the pointer. Determining the measured air pressure value of the meter according to the current position of the pointer can be to query the air pressure value corresponding to the scale where the current position of the pointer is located in the air pressure comparison table as the measured air pressure value of the meter, or to determine the model of the current meter, determine the air pressure value accuracy corresponding to the model according to the model of the meter, and calculate the measured air pressure value of the meter based on the air pressure value progress corresponding to the model and the air pressure value of the pointer corresponding to the current position of the model. It can also be that the air pressure measurement ranges corresponding to different meter models are different, and it is necessary to determine the air pressure value corresponding to the current position of the pointer according to the air pressure measurement range corresponding to the meter model.

[0076] S320. Obtain the temperature in the area where the meter is located by using the temperature sensor, and find the standard air pressure value corresponding to the temperature in the area in the temperature standard comparison table to obtain the standard air pressure value corresponding to the meter;

[0077] In specific implementation, the temperature standard comparison table can be a standard comparison table of air pressure and temperature formulated according to the ambient temperature where the meter and the inflation device are installed, and is used to determine the standard air pressure value of the charging device corresponding to the temperature according to the temperature. Determine the measured air pressure value of the meter using the current position of the pointer. At the same time, use the temperature sensor in the monitoring device to obtain the temperature in the area where the meter is located. Use the temperature in the area to look up the standard air pressure comparison table to determine the standard air pressure value corresponding to the temperature in the area, and use the standard air pressure value corresponding to the temperature in the area as the standard air pressure value corresponding to the meter. The standard air pressure value corresponding to the meter can be compared with the measured air pressure value of the meter to determine whether the inflated device measured by the meter leaks.

[0078] S330. Calculate the difference between the standard air pressure value and the measured air pressure value, and determine whether the difference between the standard air pressure value and the measured air pressure value is greater than the preset difference threshold.

[0079] In specific implementation, set the difference threshold in advance according to actual requirements or experimental data, that is, the error range between the standard air pressure value and the measured air pressure value. Determine whether the measured air pressure value is within the error range corresponding to the standard air pressure value through the preset difference threshold. If the measured air pressure value is within the error range corresponding to the standard air pressure value, it means that the inflated device measured by the meter does not leak, and continue with normal monitoring; if the measured air pressure value is not within the error range corresponding to the standard air pressure value, and the standard air pressure value is greater than the measured air pressure value, the inflated device measured by the meter leaks, and it is necessary to regularly replenish the air in the inflated device or repair the leakage point of the inflated device.

[0080] S340. When the difference is greater than the preset difference threshold, the inflated device measured by the meter leaks.

[0081] S350. Obtain the daily air pressure value at a fixed time every day within a preset time period according to the collection date of the measured air pressure value, and draw a daily change curve based on the daily air pressure values and the measured air pressure value.

[0082] In specific implementation, set the time period in advance according to actual requirements or experimental data. Draw a daily change curve with an obvious change trend through the daily air pressure values of the inflated device within the preset time period. The daily air pressure change value corresponding to the daily change curve can be determined according to the slope value of the daily change curve within the preset time period, so as to determine the maintenance time of the inflated device according to the daily air pressure change value, the measured air pressure value, and the locking air pressure value.

[0083] S360. Determine the daily change air pressure value corresponding to the measured air pressure value according to the daily change curve, and determine the maintenance time of the inflated device according to the daily air pressure change value, the measured air pressure value, and the locking air pressure value.

[0084] In a specific implementation, the daily air pressure change value can be the change value of each day of the inflation device within a preset time period determined according to the daily change curve, which is used to determine the time length required for the measured air pressure value to reach the locking air pressure value based on the daily change value. Among them, the daily change air pressure value corresponding to the measured air pressure value can be determined based on the measured air pressure value and the historical air pressure data within the preset time period. By using the change trend corresponding to the daily change curve and the daily change value, predict the time required for the measured air pressure value to reach the locking threshold, and determine the maintenance time based on this time and the date corresponding to the measured air pressure value, so as to maintain the normal operation of the inflation device, formulate an accurate maintenance schedule, reduce the patrol frequency of operation and maintenance personnel, and improve work efficiency.

[0085] In the embodiment of the present invention, it is possible to re-judge whether the daily change curve and the measured air pressure value are abnormal according to the locking threshold, air pressure value warning threshold and daily change air pressure threshold of the inflation device. If it is abnormal, corresponding warning signals can be set according to different types of abnormal states, so that the operation and maintenance personnel can determine the air pressure drop rate and the type of abnormality through the monitoring data.

[0086] In the embodiment of the present invention, by obtaining the static position of the pointer, and determining the rotation angle of the pointer through the magnetized sheet and the induction chip, the measured air pressure value of the meter is determined according to the static position and the rotation angle; the temperature sensor is used to obtain the temperature in the area where the meter is located, and the standard air pressure value corresponding to the meter is determined according to the temperature in the area; whether the inflation device measured by the meter leaks is determined according to the standard air pressure value and the measured air pressure value; when the inflation device measured by the meter leaks, the maintenance time is determined according to the daily change curve and the measured air pressure value. That is, in the embodiment of the present invention, by installing the meter in the monitoring device, when the pointer rotates, the rotation angle of the pointer can be obtained in time to determine the measured air pressure value of the meter, monitor the meter without the participation of operation and maintenance personnel, and can determine whether the inflation device leaks by using the correspondence between temperature and air pressure value, reducing the workload of operation and maintenance personnel.
