This mechanism allows highly precise adjustment. At the same time, the reset spring is sleeved on the threaded rod and located between the transmission groove and the adjustment block, which can effectively maintain the stability of the adjustment block and prevent accidental displacement. During the movement of the adjustment block, it will drive the first transmission wheel to flip. The meshing transmission movement between the first transmission wheel and the second transmission wheel enables the driving wheel to cooperate with the three-phase connection cable to achieve vertical movement. The upper end limiter of the three-phase connection cable bears force and cooperates with the connecting member. The limiter ensures the fixity and detachability of the three-phase connection cable, which is convenient for subsequent maintenance and adjustment. In addition, the design of the entire system not only improves the convenience of operation, but also optimizes the operating efficiency of the equipment. The matching design of the adjustment block, the transmission wheel and enables the detection device to flexibly respond to different working environments and requirements. At the same time, the application of the reset spring also adds an extra layer of safety protection to the system. The operator can quickly and accurately adjust and maintain the state of the transformer, thereby ensuring the stability and safety of the power system.

[0022] 2. The software control unit is designed to achieve comprehensive monitoring and management of transformers. The key lies in the efficient coordination of multiple modules. The three-phase power measurement module uses high-precision sensors to capture current, voltage and power data in real time to ensure the accuracy of electrical signals and lay the foundation for subsequent analysis. The temperature monitoring module monitors temperature changes through internal and external sensors and triggers the early warning system in time to prevent equipment damage caused by overheating, thereby ensuring the normal operation of the transformer. The oil quality analysis module evaluates the insulation performance of transformer oil by monitoring indicators such as moisture, acid value and dielectric strength to ensure timely detection of oil deterioration and reduce potential risks. The insulation monitoring module is responsible for detecting insulation resistance and dielectric constant to ensure the normal operation of the insulation system and provide real-time early warning information. To prevent safety hazards caused by insulation failure, the vibration monitoring module monitors the vibration condition of the transformer, can promptly identify mechanical failures or abnormal operation, and provide relevant data to assist fault diagnosis. The communication module is responsible for securely transmitting all monitoring data to the remote monitoring system or data center through the selected communication protocol to ensure the reliability and timeliness of the data. The raw data of all modules are concentrated in the data processing module for fusion and analysis to generate intuitive reports and suggestions to help maintenance personnel make timely decisions. Through the digital display board, real-time detection data is presented in a visual form, further enhancing the operator's feedback ability. The integrated design of the control unit not only improves the safety and stable operation of the transformer, but also provides strong support for the intelligent management and optimization of the power system.
