Research on Arc-free on-load Voltage Regulation Technology for 10kV Power Transformer

This study focuses on the application and optimization of arc-free on-load voltage regulation technology in 10 kV power transformers, exploring its advantages and limitations in the voltage regulation process. By improving the structural design of the arc-free regulator, the arc phenomenon during regulation is reduced, enhancing the transformer’s stability and lifespan. The paper combines practical application data analysis to propose optimization solutions and examines its performance in scenarios with grid load fluctuations and shortterm voltage variations. The results show that this technology significantly improves power quality and ensures stable operation of the power system, especially in voltage management for medium and low-voltage distribution systems.
