Overview

Simulation reveals strong link between load rates and hotspot temperature rise in oil-immersed transformers, indicating challenges in thermal management.

Key Points

  • Hotspot temperature rise is influenced significantly by load rates and ambient temperature, especially in summer.
  • Error control of the constructed model is within 4.1% when verified against measured data.
  • Simulation employs discrete-velocity lattice Boltzmann method for optimizing thermal analysis.
  • Highlights the pressing need for thermal management optimization in oil-immersed transformers under varying conditions.
