[0027] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0028] like Figure 1 As shown, the utility model provides a transformer wire clamp state monitoring device 1 based on a fusion terminal, including a microprocessor module 11, the microprocessor module 11 is connected to a power supply module 12 for power supply, a temperature sensor 13 for detecting the temperature around the wire clamp, a strain gauge 14 for detecting the tension around the wire clamp, and a communication module 15 for communicating with the substation intelligent fusion terminal 2.
[0029] When in use, the microprocessor module 11 collects temperature information around the wire clamp through the temperature sensor 13, and collects tension information around the wire clamp through the strain gauge 14. After a preset time, the microprocessor module 11 transmits the collected temperature information and tension information to the station area intelligent fusion terminal 2 through the communication module 15.
[0030] When it is windy, the cable will swing back and forth under the action of wind. As the cable swings, its temperature will rise. The increase in cable temperature will cause its current carrying capacity to decrease. The reduced current carrying capacity will increase resistance, which will cause melting and breaking. The transformer clamp status monitoring device based on the fusion terminal of the utility model can not only report data through (real-time) remote signaling, but also monitor the clamp status through abnormal data and messages. This device has stronger environmental adaptability and is more practical.
[0031] Optionally, microprocessor module 11 adopts STM32F103C8T6 chip. STM32F103C8T6 is a 32-bit microcontroller based on ARMCortex-M core STM32 series, with a program memory capacity of 64KB, a voltage of 2V~3.6V, and an operating temperature of -40°C~85°C. Functional modules such as memory control unit, system control unit, interrupt controller and clock controller are integrated around the STM32F103C8T6 chip, and these modules work in coordination so that the processor can perform tasks quickly and efficiently. In addition, the chip can also complete corresponding functions by connecting other chips. In the present embodiment, the chip is connected with a temperature sensor, a strain gauge and a communication module.
[0032] Optionally, the power module 12 uses a rechargeable lithium battery and / or a solar panel. Lithium batteries and solar panels are not only economical and low in maintenance cost, but also easy to install.
[0033] Optionally, the temperature sensor 13 uses an ES52 chip. When the temperature around the clamp changes, the resistance or potential inside the temperature sensing element will also change, resulting in a change in the output electrical signal. The change in the electrical signal can be read and processed by the microprocessor module 11 and then uploaded to detect the temperature.
[0034] Optionally, the strain gauge 14 is a resistance strain gauge, a semiconductor strain gauge or an optical strain gauge. When the wire clamp is slightly deformed by an external force (i.e., the tension around the wire clamp changes), the sensitive grid and other components in the strain gauge 14 will deform as the material stretches or shortens, causing its resistance value to change. This change in resistance causes a change in the output electrical signal. The change in this electrical signal can be read and processed by the microprocessor module 11 and the detected tension can be uploaded.
[0035] Optionally, the communication module 15 is a GPRS module. The GPRS module is mainly based on the GSM network, and realizes packet data transmission by introducing two new network nodes: GPRS Serving Support Node (SGSN) and Gateway Support Node (GGSN) on the original GSM network based on circuit switching (CSD) mode.
[0036] In order to locate the transformer wire clamp with abnormal wire clamp status, various methods that can be easily thought of by those skilled in the art can be adopted. The utility model preferably adopts the following method: the microprocessor module 11 is also connected to the fault locating module 16.
[0037] In specific implementation, the fault location module 16 can be used to specify the occurrence point of the fault area, and compare the device abnormality evaluation value of each fault sub-area with the preset device abnormality evaluation threshold, which can improve the fault location analysis level of the substation line.
[0038] Optionally, the fault location module 16 uses a GPS positioning chip;
[0039] Alternatively, the fault location module 16 may use a Beidou positioning chip;
[0040] Alternatively, the position information of the transformer clamp may be pre-stored in the fault location module 16 .
[0041] In specific implementation, when the fault location module 16 adopts a GPS positioning chip, the fault location module 16 located on the ground detects the spread spectrum signal sent by the GPS satellite, obtains the arrival time information through relevant operations and calculates the distance from the satellite to the receiver, and then calculates the spatial position of the satellite in combination with the ephemeris information broadcast by the satellite to complete the positioning calculation.
[0042] When the fault location module 16 uses a Beidou positioning chip, the position of each satellite and the distance from the fault location module 16 to the satellite form a sphere. The intersection of three spheres can determine a unique point, namely the position of the fault location module 16 .
[0043] On the other hand, the utility model provides a transformer clamp status monitoring system based on a fusion terminal, such as Figure 1 As shown, it includes an area intelligent fusion terminal 2 and the above-mentioned transformer line clamp status monitoring device 1 based on the fusion terminal.
[0044] Optionally, the transformer wire clamp status monitoring system based on the fusion terminal also includes a distribution Internet of Things cloud master station platform 3 that is communicatively connected to the substation intelligent fusion terminal 2.
[0045] During use, when the tension around the wire clamp reaches a certain value, or the temperature around the wire clamp reaches a certain value, the abnormal data or abnormal message reported to the distribution Internet of Things cloud master platform 3 can be reported through the substation intelligent fusion terminal 2, and then located through the fault location module 16. The distribution Internet of Things cloud master platform 3 will know where the hidden danger occurs at the first time and take corresponding measures in time.
[0046] When it is windy, the cable will swing back and forth under the action of wind. As the cable swings, its temperature will rise. The increase in cable temperature will cause its current carrying capacity to decrease. When the current carrying capacity decreases, the resistance will increase, which will cause melting and breaking. When the tension around the wire clamp reaches a certain value, or the temperature around the wire clamp reaches a certain value, the system reports abnormal data or abnormal messages to the distribution Internet of Things cloud master platform 3 through the substation intelligent fusion terminal 2, and then locates the fault through the fault location module 16 of the transformer wire clamp status monitoring device 1. The distribution Internet of Things cloud master platform 3 will know where the hidden danger occurs at the first time and take corresponding measures in time.
[0047] In addition, by creating a corresponding container in the substation intelligent fusion terminal 2 and installing the corresponding app, the default timed reporting cycle can be set to report data to the main station regularly, and it can also be viewed in real time through real-time SOE records.
[0048] The utility model is based on the fusion terminal transformer wire clamp status monitoring system, which can not only report data in real time through remote signaling, but also monitor the wire clamp status in real time through abnormal data and messages. This device has stronger environmental adaptability and is more practical.
[0049] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
