Description

TECHNICAL FIELD

[0001] The application relates to the technical field of voltage monitoring, in particular to a non-electricity intelligent platen voltage acquisition unit and a platen live warning system thereof. BACKGROUND

[0002] In a modern power system, as a key control element, the voltage state monitoring of a platen is of great significance to the safe and stable operation of the power grid. Traditional platen voltage measurement mostly adopts a contact type measurement method, such as using a multimeter or a special platen meter to measure and check the potential. However, this method has many disadvantages: 1. The operator needs to directly contact the live platen, and in a high-voltage environment, once misoperation occurs, it is easy to cause an electric shock accident, which seriously threatens personal safety. For example, when measuring the platen of a 110kV and above voltage level substation, if the operator operates improperly, instantaneous contact with high voltage can cause fatal injury. 2. The number of platens in a substation is huge, and the potentials of different platens are different. Artificially checking the potential meter one by one is tedious, time-consuming, and easily affected by subjective factors, which increases the probability of misjudgment. Taking a medium-sized 110kV substation as an example, the number of platens in the station can reach hundreds, and it often takes several hours or even longer to complete a comprehensive measurement, and the accuracy of the measurement results cannot be guaranteed. 3. With the development of the power system, the secondary circuit wiring is becoming more and more complex, and the platen on-off state and voltage value often change due to factors such as equipment modification, which makes the potential meter need to be frequently updated, and the maintenance and management cost increases greatly. Moreover, when maintaining the complex secondary circuit, the traditional measurement method cannot quickly and accurately determine the platen state, which affects the maintenance efficiency.

[0003] To solve the above problems, although non-contact platen state monitoring methods have appeared, the existing technology still has limitations: 1. Some non-contact measurement methods have low detection accuracy due to the limitation of the measurement principle, and cannot accurately reflect the actual voltage state of the platen; 2. The working performance of the sensor is unstable under different environmental conditions (such as temperature, humidity, electromagnetic interference, etc.), resulting in large measurement result deviation. In a high-temperature, high-humidity or strong electromagnetic interference environment, the measurement error of some sensors can even exceed ±20%, which seriously affects the reliability of the measurement data; 3. Some non-contact sensors have high manufacturing and maintenance costs, and their reliability needs to be improved, which makes it difficult to meet the requirements of long-term stable monitoring of the power system. The price of some high-precision non-contact sensors is several times that of traditional sensors, and they are prone to failure during use, increasing the operation cost and maintenance difficulty of the power system. The present project aims to develop a non-electricity intelligent platen voltage acquisition unit to solve the problem. CONTENT OF THE UTILITY MODEL

[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the present application.

[0037] In this embodiment of the present application, as shown in Figs. 1-4 , a non-electric quantity intelligent pressure plate voltage acquisition unit is provided, characterized by comprising:

[0038] The induction groove 1 is used to induce the electric field of the measured pressure plate pile head conductor, and the output ends thereof are respectively connected with the input ends of the first coulomb charge meter 3 and the second coulomb charge meter 4;

[0039] The mirror electrode plate 2 cooperates with the induction groove 1 to generate corresponding charges under the action of the electric field, and the output ends thereof are respectively connected with the input ends of the first charge pump 5 and the second charge pump 6;

[0040] The first coulomb charge meter 3 and the second coulomb charge meter 4 are used to integrate and measure the current generated in the induction process, and the output ends of the first coulomb charge meter 3 and the second coulomb charge meter 4 are respectively connected with the input ends of the core MCU module 9;

[0041] The first charge pump 5 and the second charge pump 6 are respectively used to generate positive voltage and negative voltage to realize the measurement of positive and negative polarity voltage, and the output ends of the first charge pump 5 and the second charge pump 6 are respectively connected with the input ends of the core MCU module 9;

[0042] The core MCU module 9 samples the integration results of the first coulomb charge meter 3 and the second coulomb charge meter 4, and performs subsequent mathematical and logical processing, and the output ends thereof are respectively connected with the input ends of the first communication module 7 and the second communication module 8;

[0043] The first communication module 7 and the second communication module 8 are used to transmit the data processed by the core MCU module 9;

[0044] The power module 10 has its output terminals connected to the power input terminals of the induction slot 1, the mirror electrode plate 2, the first coulomb charge meter 3, the second coulomb charge meter 4, the first charge pump 5, the second charge pump 6, the core MCU module 9, the first communication module 7, and the second communication module 8, respectively, to provide power support for the entire system.

[0045] The induction tank 1 of this system serves as an electric field sensing component, effectively sensing the electric field surrounding the conductor of the tested pressure plate pile. When an electric field is present, the induction tank 1 generates a corresponding charge change due to the electric field, which is output as current to the first coulomb charge meter 3 and the second coulomb charge meter 4. The mirror electrode plate 2 works in conjunction with the induction tank 1; under the electric field environment, the mirror electrode plate 2 accumulates charges opposite to those of the induction tank 1. Its output is connected to the first charge pump 5 and the second charge pump 6 for subsequent voltage generation. The first coulomb charge meter 3 and the second coulomb charge meter 4 possess high-precision integration measurement capabilities, accurately integrating and measuring the current output from the induction tank 1, and transmitting the measurement results to the core MCU module 9. The first charge pump 5 and the second charge pump 6 are responsible for generating positive and negative voltages respectively to meet the requirements for measuring voltages of different polarities; the generated voltage signals are also transmitted to the core MCU module 9. The core MCU module 9, serving as the system's control and processing center, samples the integration results from the coulomb charge meter and performs subsequent processing using specific mathematical algorithms and logical judgment rules. The processed data is then transmitted to external devices or systems via the first communication module 7 and the second communication module 8. The power supply module 10 stably provides the necessary power to all components of the system, ensuring their normal operation. Through the rational arrangement and connection of these components, a complete and functionally defined non-electrical quantity intelligent pressure plate voltage acquisition unit is constructed. This system can efficiently automate the entire process from electric field induction, charge measurement, voltage generation, data processing to data transmission, ensuring the accuracy and stability of voltage acquisition and providing a reliable foundation for subsequent analysis and judgment based on voltage data.

[0046] The electrical parameters of the mirror electrode plate 2 are completely equal to those of the induction groove 1. The mirror electrode plate 2 plays an important role in the system, and its electrical parameters are completely equal to those of the induction groove 1, which is obtained through accurate design and calculation. The mirror electrode plate 2 exists in the form of a specific wiring on a PCB board. The design of the specific wiring enables it to have an accurate charge correspondence relationship with the induction groove 1 in the same electric field environment. In actual work, when the induction groove 1 gathers electric charges due to the electric field effect, the mirror electrode plate 2 will gather opposite electric charges according to the same electrical characteristics, thereby providing stable and consistent conditions for subsequent accurate voltage measurement. Due to the consistency of the electrical parameters of the mirror electrode plate 2 and the induction groove 1, the actual electric field situation can be more accurately simulated and reflected during the electric field induction process, effectively reducing the measurement error caused by the difference in electrical parameters, greatly improving the accuracy of voltage measurement, and enabling the system to more accurately obtain the actual voltage value of the pile head, thereby providing reliable voltage data support for the stable operation and fault diagnosis of the power system.

[0047] The application also includes switches K1, K2, K3 and K4 for controlling the discharge and charging of electric charges and the on-off state of the circuit during voltage acquisition, so as to realize voltage measurement operations in different stages. One end of the first charge pump 5 is connected to the mirror electrode plate 2 through the switch K1, and the other end is connected to the power module 10VCC. One end of the second charge pump 6 is connected to the mirror electrode plate 2 through the switch K2, and the other end is connected to the power module 10VCC. One end of the switch K3 is connected to the induction groove 1, and the other end is grounded. One end of the switch K4 is connected to the mirror electrode plate 2, and the other end is grounded. The switches K1, K2, K3 and K4 play a key control role during voltage acquisition. In different measurement stages, the closing and opening of these switches can realize accurate adjustment of the discharge, charging and on-off state of the circuit. For example, in the initial measurement stage, closing the switches K3 and K4 can make the electric charges of the induction groove 1 and the mirror electrode plate 2 discharge to the ground, and initialize their charge states. Then, opening the switch K4 can make the induction groove 1 polarize to generate current by using the electric field and charge skin effect. In subsequent charging operations, the switching of the switches will also be controlled according to the needs of the measurement process, so as to ensure that the entire measurement process can proceed smoothly according to the predetermined steps. The setting of these switches makes the voltage acquisition process highly controllable. The operator or the system can flexibly control the switch state according to different measurement needs and stages, so as to accurately adjust the flow of electric charges and the on-off state of the circuit, and ensure the accuracy and orderliness of the measurement steps. This accurate control helps to improve the reliability and stability of measurement, reduces measurement errors or faults caused by improper control of the circuit state, and improves the performance of the entire voltage acquisition system.

[0048] The application also includes a background automatic monitoring module for receiving data sent after processing by the core MCU module 9; the background automatic monitoring module is an important component of the system, and its main function is to receive data sent after processing by the core MCU module 9. This module has powerful data processing and analysis capabilities and can store, classify, and statistically operate the received data. At the same time, it can also interact and share data with other related power system management software or platforms, so that the management personnel of the power system can understand the state information of the pressure plate voltage in real time and comprehensively; the existence of the background automatic monitoring module enables the system to realize remote monitoring and automatic management. The power system management personnel can obtain the pressure plate voltage data without going to the site, greatly improving the management efficiency. Through the analysis and processing of a large amount of voltage data, voltage abnormal trends and potential problems can be found in time, and preventive measures can be taken in advance to ensure the stable operation of the power system. In addition, the data interaction function with other systems also promotes the informatization and intelligent development of the power system, providing strong support for the comprehensive management and optimal scheduling of the power system.

[0049] The application also includes a voltage acquisition method, and the specific steps include:

[0050] First step: close switches K3 and K4 for a period of time to discharge the charges of the induction groove 1 and the mirror electrode plate 2 to the ground, then disconnect switch K4, and under the action of the electric field and the charge skin effect, the induction groove 1 is polarized to generate a current, which is integrated and measured by the second Coulomb charge meter 4 and sampled and recorded by the core MCU module 9; this step initializes the states of the induction groove 1 and the mirror electrode plate 2 by discharging, enhances the induction signal by using the charge skin effect, and ensures the consistency and accuracy of the initial state of the measurement;

[0051] Second step: after the second Coulomb charge meter 4 detects that the current is 0, close switch K4 to make the induction groove 1 and the electric field mirror electrode plate 2 both have 0 charges; this step resets the charge state for the next measurement and eliminates the interference of the residual charges of the last measurement on the subsequent measurement.

[0052] Third step: disconnect switch K3, close switch K2 to turn on the second charge pump 6, and the second charge pump 6 charges the mirror electrode plate 2; when the count values of the first Coulomb charge meter 3 and the second Coulomb charge meter 4 are equal, the second charge pump 6 stops boosting, and at this time the output voltage of the second charge pump 6 is equal to the voltage of the pressure plate pile head; this process is based on Coulomb's law and the relationship between electric field strength and voltage, and through accurate control of the boosting process of the second charge pump 6 and comparison of the Coulomb meter count, accurate measurement of the voltage of the pressure plate pile head is realized.

[0053] Fourth step: disconnect switch K2, turn off the second charge pump 6, return to the first step for continuous real-time measurement; when the measured voltage is negative voltage, disconnect switch K2 between the first step and the fourth step, turn off the second charge pump 6, open switch K1, open the first charge pump 5 to participate in the cycle measurement, the positive and negative polarity of the charge measured by the coulomb meter determines the opening of the first charge pump 5 or the second charge pump 6; This flow design realizes the continuous real-time measurement of positive and negative polarity voltage, improves the comprehensiveness and timeliness of the measurement.

[0054] The voltage acquisition method realizes continuous real-time measurement of positive and negative polarity voltage. Through accurate control of the charge state and orderly execution of the measurement steps, the accuracy and reliability of the measurement can be effectively improved. The continuous real-time measurement function enables the system to capture the voltage change in time, providing real-time and accurate data support for the operation monitoring and fault diagnosis of the power system. At the same time, the scientificity and rigor of this method also guarantee the stability and consistency of the measurement results, reduce the measurement error and uncertainty, and improve the performance and practicality of the entire voltage acquisition system.

[0055] The above voltage acquisition method is based on the assumption that the electric field direction is positive. If the pressure plate pile head voltage is negative, such as equal to -110V, then in the above steps, the charge recorded by the coulomb meter is also negative. In order to generate a negative electric field for the mirror electrode plate 2, a negative charge pump is needed. Due to the current technical conditions, a charge pump can only either step up to generate a positive voltage or step down to generate a negative voltage, and cannot do both at the same time. Therefore, we use double charge pumps, one for generating positive voltage and the other for generating negative voltage. When the external electric field or external voltage is negative, disconnect switch K2 between the first step and the fourth step, turn off the second charge pump 6, open switch K1, open the first charge pump 5 to participate in the above cycle measurement. The specific time when the first charge pump 5 needs to be opened and the second charge pump 6 needs to be opened is determined by the positive and negative polarity of the charge measured by the coulomb meter. In this way, the purpose of measuring both positive and negative polarity is achieved.

[0056] The voltage acquisition method employs a non-contact measurement approach, avoiding direct contact between operators and the voltage plate. This means the induction tank 1 does not need to directly contact the conductor at the test plate's terminal; instead, voltage measurement is achieved by inducing the surrounding electric field. This method prevents operators from directly contacting the voltage plate during measurement, reducing safety risks associated with contact with live components. The non-contact method significantly improves operator safety and reduces the probability of electric shock and other accidents. Simultaneously, it reduces equipment damage and measurement errors caused by contact. Furthermore, non-contact measurement makes the operation more convenient, eliminating the need for complex insulation measures, improving measurement efficiency, and making it suitable for various complex power environments. It provides a safe, reliable, and efficient solution for voltage measurement in power systems.

[0057] like Fig. 5 As shown, this application also discloses a voltage warning system for a pressure plate, applied to a non-electrical quantity intelligent pressure plate voltage acquisition unit, which includes:

[0058] Multiple pressure plate status acquisition units are used to collect the engagement and disengagement status of the pressure plates.

[0059] The intelligent pressure plate acquisition terminal is used to transmit the acquired pressure plate deployment and deployment status and pressure plate pile head voltage to the dispatch communication backend server.

[0060] The dispatch communication backend server processes the on / off status of the pressure plates and the voltage at the pressure plate terminals, as transmitted from the intelligent pressure plate acquisition terminals. When the voltage at the pressure plate terminals reaches a preset value, it sends an early warning signal to the user. This helps avoid serious consequences such as damage to electrical equipment and power system failures caused by abnormal voltage, ensuring the safety and reliability of the power system. At the same time, timely warnings buy valuable time for fault diagnosis and repair, reducing power outage time and economic losses caused by faults.

[0061] Preferably, the plurality of pressing plate state acquisition units are provided with three-color lights, and when the pressing plate voltage reaches the preset value, the three-color light above the corresponding pressing plate will flash continuously. The three-color light can be set to different colors to represent different voltage abnormality degrees or types, for example, red represents serious voltage abnormality, yellow represents general voltage fluctuation, etc. Through the flashing and color change of the light, the operator can quickly and intuitively understand the abnormality of the pressing plate voltage; the setting of the three-color light makes the early warning information more intuitive and eye-catching. During the inspection or monitoring process, the operator can quickly obtain voltage abnormality information through the change of the light, without the need to check complex data reports in detail. This improves the timeliness and accuracy of fault discovery, helps the operator to quickly respond and take corresponding measures for processing, reduces the misjudgment and delay caused by the delay or non-intuitive information transmission, and further improves the operation safety and reliability of the power system.

[0062] The screen cabinet is provided with a plurality of wired pressing plate state acquisition units on the front face, and the acquisition units are provided with three-color lights. The plurality of state acquisition units acquire the on-off state of the pressing plate, and the non-electricity intelligent pressing plate voltage acquisition unit on the back face of the screen cabinet acquires the pressing plate stake head voltage. The on-off state of the pressing plate and the pressing plate stake head voltage are uniformly acquired by the intelligent pressing plate acquisition terminal, and then further sent to the dispatching communication background server for further subsequent application processing. The system itself has a pre-warning and warning function. When the voltage of a certain pressing plate reaches a preset value such as 110V, the red light above the corresponding pressing plate will flash in connection, prompting the operator that the pressing plate has electricity and the operation should be cautious. The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any skilled person in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, any equivalent changes made according to the shape, structure and principle of the present application, without departing from the technical solution of the present application, should be covered by the protection scope of the present application.
