1. Reliability of Insulation Technology
Our research spans from initial two-dimensional electric field simulations, three-dimensional electric field measurements, and impact characteristic measurements to later-stage theoretical analysis and simulated experiments on the main insulation, longitudinal insulation, end insulation, insulation of leads, and coil withstand voltage characteristics of transformers. Through years of verification using various methods, we ensure the reliability of transformer insulation.
2. Calculation of leakage magnetic field and reduction of stray loss
Dedicate specialized efforts to calculating and measuring transformer leakage magnetic fields. The research includes shielding structures for leakage magnetic fields, calculations for transformer dynamics and thermal stability, and improvements in transformer dynamic and thermal stability to guarantee accurate calculations and reduced stray losses, thereby enhancing transformer dynamic stability.
3. Precise Analysis of Coil Temperature Fields
Collaborating with numerous domestic universities, we jointly developed programs for calculating coil temperature fields. These programs calculate loss distribution in coils, including resistive losses, eddy current losses in different directions, and circulating losses between parallel conductors, as well as flow field cooling conditions. This enables the accurate calculation of coil temperature distribution and hotspot temperature rises, allowing us to take measures to effectively control hotspot temperature rises that impact transformer lifespan.
4. Reducing Local Discharge in Transformers
Electric field strengths at various locations have undergone numerical analysis during the design phase and have been strictly controlled. Additionally, compliance with manufacturing quality, the reliability of processing methods, and the reasonableness of operating techniques effectively control local discharges in transformers.
