Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent measurement and control, and in particular to a method, device and terminal equipment for transformer condition monitoring based on vibration. Background Technology
[0002] The vibration state of a transformer during operation and the gas generation state during sudden internal faults are important characteristics characterizing its operating status. A gas relay is installed inside the transformer, and the transformer is closely connected to the gas relay, which can transmit vibrations. Under normal conditions, the gas relay is filled with oil. When gas is present, the gas rises to the upper part of the gas relay, thus forcing the insulating oil into the oil tank.
[0003] For the gas production status during a fault, two common measures are oil chromatography monitoring and gas relay protection. However, both of these methods obtain the gas production rate by monitoring the changes in insulating oil over a period of time. These two methods cannot quickly and in real time monitor the gas production rate during a fault, resulting in a lag in fault judgment.
[0004] Therefore, there is an urgent need for a transformer condition monitoring strategy to solve the problem of low efficiency in current transformer condition monitoring. Summary of the Invention
[0005] This invention provides a vibration-based transformer condition monitoring method, apparatus, and terminal equipment to improve the monitoring efficiency of transformer condition.
[0006] To address the above problems, one embodiment of the present invention provides a vibration-based transformer condition monitoring method, comprising:
[0007] The electrical signal transmitted by the piezoelectric material is acquired to obtain state data; wherein the piezoelectric material is connected to the inner upper wall of the target relay;
[0008] Based on the state data, the liquid height in the target relay is obtained using the vibration height calculation formula;
[0009] Based on the liquid level, the gas production rate of the target relay is obtained, and the gas production rate is transmitted to the user terminal so that the user terminal can determine the transformer status based on the gas production rate; wherein, the transformer status includes: normal status or abnormal status; and the target relay is connected to the transformer.
[0010] As can be seen from the above, the present invention has the following beneficial effects:
[0011] This invention provides a vibration-based transformer condition monitoring method. By acquiring state data transmitted through piezoelectric materials, the operating status of a target relay can be reflected based on the acquired state data. The state data is then used to calculate the liquid level of the target relay using a vibration height calculation formula. The gas generation rate of the target relay is then determined based on the liquid level and transmitted to the user terminal. The user terminal can then judge the transformer's condition based on the gas generation rate of the target relay, thereby achieving transformer condition monitoring. This invention acquires relay state data in real time through piezoelectric materials and uses the calculated liquid level to determine the relay's gas generation rate, thus reflecting the internal state of the transformer in real time. This improves the accuracy and real-time performance of transformer condition monitoring, thereby increasing the efficiency of transformer condition monitoring.

By receiving the amplitude and frequency of the electrical signal transmitted by the piezoelectric material, the vibration amplitude and frequency data are obtained through analysis, thereby obtaining the vibration amplitude and frequency of the target relay, laying the foundation for real-time monitoring of the transformer.
[0021] As an improvement to the above solution, the step of obtaining the gas generation rate of the target relay based on the liquid height specifically involves:

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0047] Example 1
[0048] See Figure 1 , Figure 1 This is a schematic flowchart of a vibration-based transformer condition monitoring method according to an embodiment of the present invention, as shown below. Figure 1 As shown, this embodiment includes steps 101 to 103, and the specific steps are as follows:
[0049] Step 101: Obtain the state data transmitted by the piezoelectric material; wherein the piezoelectric material is connected to the inner upper wall of the target relay.
[0050] In this embodiment, acquiring the state data transmitted by the piezoelectric material specifically involves:
[0051] Receive electrical signals transmitted by piezoelectric materials based on the vibration of the target relay;
[0052] The vibration amplitude and vibration frequency are obtained based on the amplitude and frequency of the electrical signal; wherein the state data includes: vibration amplitude and vibration frequency.
[0053] In one specific embodiment, the target relay may be a gas relay.
[0054] In one specific embodiment, the piezoelectric material is attached to the upper inner wall of the gas relay. When the transformer vibrates, causing the gas relay to vibrate, the mass block at the head of the device vibrates, causing the piezoelectric material to stretch or compress, thereby generating an electrical signal. The vibration amplitude and vibration frequency are obtained based on the value and frequency of the electrical signal.
[0055] When the gas relay is filled with insulating oil, the vibration amplitude and frequency of the metal block at the head of the device are relatively small. When there is gas in the gas relay, the height of the vibrating device buried in the liquid level is different, and the viscous force it experiences decreases compared to when it is completely submerged in the insulating oil. As a result, the vibration amplitude and frequency will change, which in turn leads to changes in the amplitude and frequency of the electrical signal.
[0056] In one specific embodiment, please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a vibration-based transformer condition monitoring device provided in another embodiment of the present invention. The device mainly consists of a housing 301, a piezoelectric material 302, a signal line 303, a cantilever beam 304, and a mass block 305. The piezoelectric material 302 is laid on both sides of the cantilever beam 304, the mass block 305 is located at one end of the cantilever beam 304, and the other end of the cantilever beam 304 and the piezoelectric material 302 are fixed to the housing 301, which is made of non-conductive and corrosion-resistant material. The piezoelectric material 302 at both ends of the cantilever beam 304 is connected to the signal line 303, and the signal line 303 is bundled out from the housing 301.
[0057] Step 102: Based on the state data, obtain the liquid height in the target relay using the vibration height calculation formula.
[0058] In this embodiment, the step of obtaining the liquid height in the target relay based on the state data using the vibration height calculation formula specifically involves:
[0059] The state data includes the vibration amplitude and frequency of the piezoelectric material. Based on the vibration amplitude and frequency, the liquid height of the target relay is calculated using the vibration height calculation formula. The vibration height calculation formula is as follows:
[0060]
[0061] Where EI is the bending stiffness of the device, ρ is the density of the device, A is the cross-sectional area, h is the depth of the device submerged in oil, ρ0 is the density of water, and z is the width of the device.
[0062] Step 103: Based on the liquid height, obtain the gas production rate of the target relay, and transmit the gas production rate to the user terminal so that the user terminal can determine the transformer status based on the gas production rate; wherein, the transformer status includes: normal status or abnormal status; and the target relay is connected to the transformer.
[0063] In this embodiment, obtaining the gas generation rate of the target relay based on the liquid height specifically involves:
[0064] Based on the liquid height, a set of liquid heights is obtained after a preset time.
[0065] Based on the set of liquid heights, the rate of change of liquid height is obtained through a preset time interval; the rate of change of liquid height is the gas production rate.
[0066] In one specific embodiment, the preset time and the preset time interval can be determined by the user based on the monitoring accuracy.
[0067] In one specific embodiment, when the gas production rate is greater than 20 cm / s, the transformer is considered to be in an abnormal state; when the gas production rate is less than or equal to 20 cm / s, the transformer is considered to be in a normal state.
[0068] In one specific embodiment, this embodiment can also monitor the acceleration of the target relay vibration by detecting the electrical signal of the piezoelectric material.
[0069] In one specific embodiment, vibration induces a piezoelectric effect in the piezoelectric material. The current generated by the piezoelectric effect is converted into direct current by a rectifier circuit. The output of the rectifier circuit is connected to the input of the energy storage device, and the direct current from the rectifier circuit charges the energy storage device. The output of the energy storage device is connected to the sensor being powered. When the sensor requires power, the energy storage device supplies power to the sensor through its output.
[0070] In one specific embodiment, for a better illustration of the mounting location of the piezoelectric material, please refer to [link to relevant documentation]. Figure 4 It includes: a vibration-based transformer condition detection device 401, a lower wall of a gas relay 402, an upper wall of a gas relay 403, an oil conservator 404, an oil tank 405, and an exhaust port 406;
[0071] The gas relay consists of a lower gas relay wall 402, an upper gas relay wall 403, and an exhaust port 406; the gas relay is connected to the oil tank 405 on the left and to the oil storage tank 404 on the right.
[0072] The rigid outer shell of the equipment is connected to the upper inner wall of the gas relay. One end of the cantilever beam is fixed to the outer shell, and the other end with the mass block is the free end. When the transformer vibrates, it drives the gas relay to vibrate, and the mass block at the other end of the cantilever beam also vibrates, causing the piezoelectric crystals on the upper and lower sides of the cantilever beam to stretch or compress.
[0073] The piezoelectric material is connected to the power transmission line. The output end of the power transmission line is connected to a voltage detection device and a rectifier circuit. The voltage detection device can record the signal amplitude and frequency generated by the piezoelectric crystal. The current after the rectifier enters the energy storage device. The output end of the energy storage device is the power system of the sensing device that needs to be powered.
[0074] The recorded piezoelectric material voltage signal is connected to a signal analysis device. After analysis, the device outputs signals such as vibration acceleration, whether gas is generated, and the gas generation rate based on the signal differences.
[0075] This embodiment acquires state data transmitted by piezoelectric materials, thereby reflecting the operating status of the target relay based on the acquired state data. The state data is then used to calculate the liquid height of the target relay using a vibration height calculation formula, and the gas generation rate of the target relay is determined based on the liquid height. This gas generation rate is then sent to the user terminal, allowing the user terminal to judge the transformer's status based on the gas generation rate of the target relay. This enables transformer status monitoring, improving monitoring efficiency and accuracy by monitoring the vibration frequency of the target relay in real time. This embodiment also utilizes a cantilever beam vibration energy harvesting device to achieve vibration energy acquisition, realizing self-sufficiency, and monitors vibration acceleration by utilizing the difference in electrical signals caused by vibration in the piezoelectric materials. This embodiment integrates power supply, vibration, and gas status monitoring functions, helping to reduce the number of transformer status monitoring devices and lowering installation and power supply difficulties.

[0091] This embodiment acquires the electrical signals transmitted by the piezoelectric material through a data acquisition module, parses the resulting state data, and then uses this state data to calculate the liquid height in the target relay through a data calculation module.
