[0016] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] The dedicated transformer collection terminal for low-voltage substations with network topology is shown in FIG1 , and includes a housing 1. Specifically, a data collection module is provided in the housing 1, and is configured to collect power parameters and equipment status information of low-voltage substations in real time, including key parameters such as voltage, current, and power, and provide real-time monitoring capabilities for the system. Through the collection of real-time data, abnormalities or faults in the power system can be quickly identified and diagnosed, and timely measures can be taken; The data recording module is configured to collect and record the power parameters and equipment status information of the current low-voltage area when the housing 1 is opened. During maintenance, the time point and status of the problem can be quickly located, which is convenient for analyzing the cause of the fault. It provides a system status record before maintenance, provides benchmark data for maintenance work, and helps maintenance personnel understand the original operating status of the system. At the same time, after maintenance, it can be compared with the recorded data to evaluate the maintenance effect and system recovery; The data comparison module is configured to collect and record the power parameters and equipment status information of the low-voltage area after the commissioning and maintenance when the housing 1 is closed, and compare them with the data of the data recording template. By comparing the data before and after the maintenance, it can be verified whether the maintenance work has achieved the expected effect and ensure the maintenance quality. If the system parameters after the maintenance are significantly different from the expectations, the data comparison can quickly find the problem and restore the data to avoid potential risks; The status monitoring module is configured to monitor the operating status of the low-voltage area, including but not limited to voltage, current, power quality, etc. By monitoring parameter changes, potential faults or abnormal conditions can be discovered in advance to ensure that the system operates within the safe parameter range and reduce safety risks; Data recovery module, which transmits and recovers power parameters and equipment status information of low-voltage areas, can prevent the system from becoming unstable due to misconfiguration or parameter drift; The data comparison module includes a comparator, the threshold of the comparator is X, and the comparator is used to compare the data of the data recording module with the data collected by the data comparison module and calculate the difference. When the value collected by the comparator is greater than its threshold, the data recovery module is started. By setting the above modules, it can be ensured that the acquisition terminal can monitor and collect the power parameters and equipment status information of the low-voltage substation in real time, ensuring the timeliness and accuracy of the data. When an abnormality is detected, the data recovery module can quickly intervene to restore the power parameters and equipment status information, reduce system failures caused by parameter errors, and reduce the complexity and error rate of manual operations through automated comparison and recovery mechanisms. The reliability of the system is improved, and the time for repeated testing and adjustments is also reduced.

[0018] Furthermore, a communication interface is provided in the housing 1, connected to the data acquisition module, and configured to send the collected data to the central monitoring system. The setting of the communication interface allows the acquisition terminal to send the real-time collected data to the central monitoring system, thereby realizing remote transmission and centralized management of the data; The data processing unit is connected to the communication interface and is configured to analyze and process the collected data. The addition of the data processing unit enables the acquisition terminal to not only collect data but also perform preliminary analysis and processing on the data, thereby improving the efficiency and intelligence of data processing; Redundancy modules ensure that when some system components fail, the remaining components can continue to operate, ensuring the continuity of data collection and monitoring.

[0019] Specifically, three grooves 2 are provided on the shell 1, and buttons 3 for debugging parameters are arranged in the three grooves 2. The three buttons 3 are respectively a reset button 3, a configuration button 3 and a test button 3. The heights of the three buttons 3 are all lower than the depth of the groove 2, that is, the distance from the top of the button 3 to the bottom of the groove 2 is less than the groove depth of the groove 2. The design of the button 3 being lower than the groove 2 can prevent these sensitive debugging buttons 3 from being accidentally touched during operation, thereby avoiding unnecessary system resets or configuration changes, and having an anti-mistouch effect. At the same time, this design can protect the button 3 from physical damage, because the button 3 is not directly exposed to the outside, reducing the risk of damage caused by impact or wear. A detachable debugging pen 4 is provided on the shell 1. The cross-sections of the debugging pen 4 and the groove 2 are both circular and the diameter of the debugging pen 4 is smaller than the diameter of the notch of the groove 2. By providing the debugging pen 4, it is ensured that only the debugging pen 4 can be accurately inserted into the groove 2, thereby improving the accuracy of the operation. When these buttons 3 need to be operated, the operator must use the debugging pen 4 And extend it into the groove 2, which helps to accurately locate the button 3 and reduce misoperation. The detachable debugging pen 4 is convenient for the operator to quickly take out or replace it as needed, and is easy to clean and keep the equipment clean and tidy. Through the above settings, while ensuring operational safety and accuracy, it also improves the durability of the equipment and the convenience of maintenance.

[0020] Two symmetrically arranged electric clamping arms 5 are provided on the shell 1, and a space for accommodating the debugging pen 4 to be embedded is formed between the two electric clamping arms 5, that is, a slide groove 6 for accommodating the sliding of the debugging pen 4 is formed on the side of the two electric clamping arms 5 facing each other. By setting the electric clamping arms 5, the electric clamping arms 5 can safely store the debugging pen 4 to prevent loss or misplacement. The operator only needs to insert the debugging pen 4 into the appropriate position in the electric clamping arms 5, and the electric clamping arms 5 will automatically clamp, simplifying the operation process. The design of the electric clamping arms 5 makes it easier to replace and maintain the debugging pen 4. By setting the slide groove 6, the debugging pen 4 can slide in the slide groove 6, which reduces direct friction with the shell 1 or other hard surfaces, facilitates the storage and access of the debugging pen 4, and extends the service life of the debugging pen 4 and the equipment.

[0021] A positioning block 7 is integrally formed on the debugging pen 4, and a positioning groove 8 for accommodating the positioning block 7 is provided on the shell 1. A guiding arc surface connected to the positioning groove 8 is provided on the shell 1. By setting the positioning block 7 and the positioning groove 8, the operator only needs to insert the positioning block 7 into the positioning groove 8 when fixing the debugging pen 4. The inner wall of the positioning groove 8 can limit the positioning block 7, so that the debugging pen 4 can be fixed on the shell 1. The guiding arc surface provides a smooth guiding path to help the positioning block 7 to be inserted into the positioning groove 8 more easily and accurately. Through the design of the guiding arc surface, the angular error of the positioning block 7 during insertion can be reduced to ensure that the positioning block 7 is correctly embedded. At the same time, the smooth guiding arc surface reduces the friction between the positioning block 7 and the positioning groove 8 during the insertion process, reducing the risk of damage to both. Furthermore, a driving module is provided at the bottom of the positioning groove 8, which is connected to the electric clamping arm 5 and is configured so that when the positioning block 7 is inserted into the positioning groove 8, the electric clamping arm 5 clamps the debugging pen 4, and when the positioning block 7 is separated from the positioning groove 8 When the electric clamping arm 5 releases the debugging pen 4, specifically, the driving module includes two metal sheets 9, and the two metal sheets 9 have a limiting column 11 integrally formed on one side facing each other, a compression spring 12 is arranged between the two metal sheets 9, and both ends of the compression spring 12 are sleeved on two symmetrically arranged limiting columns 11, the operator inserts the positioning block 7 into the positioning slot 8 and makes the two metal sheets 9 approach each other, at this time, the metal sheet 9 will contact with the conductive sheet 10, at this time, the conductive sheet 10 transmits a signal and drives the two electric clamping arms 5 to rotate, further, a limiting ring 13 is provided in the positioning slot 8 to prevent the metal sheet 9 from escaping from the positioning slot 8, thereby ensuring the stability of the metal sheet 9 in the positioning slot, and the automatic clamping and releasing of the debugging pen 4 is realized through the automatic control of the driving module, thereby reducing the need for manual operation, the operator only needs to insert the debugging pen 4 into the positioning slot 8, and the electric clamping arm 5 will automatically clamp, thereby simplifying the process of taking the debugging pen 4, the positioning block 7 and the positioning slot 8 The design ensures that the debugging pen 4 will not roll or shift on the housing 1, reducing the risk of loss or misalignment. At the same time, the integrated positioning block 7 and positioning slot 8 design maintains the neat appearance of the device and improves its aesthetics.
