1. Introduction1.1 Key Role of Transformers in Power SystemsTransformers are the cornerstone of power systems, acting as the "central nervous system" for electricity transmission and distribution. They leverage electromagnetic induction to efficiently convert AC voltages, enabling long-distance power transmission and appropriate voltage distribution. In power generation, transformers step up voltage to minimize line losses during transmission. At the consumption end, they step down high voltage to suitable levels for households, industries, and other applications. Transformers are indispensable for urban power grids, industrial power supplies, and household electricity, ensuring stable and safe power supply. Their reliable operation directly impacts the safety and efficiency of power systems, making them essential components.

1.2 Importance of Transformer Insulation for Performance and LifespanInsulation systems play a critical role in transformers, safeguarding operational safety and extending service life. Effective insulation separates conductive components, preventing unintended current flow and short circuits, ensuring stable voltage conversion and energy transmission. High-quality insulation reduces energy losses, enhancing transformer efficiency. Additionally, it resists environmental factors like moisture and temperature fluctuations, slowing component aging. During overvoltage events, robust insulation protects internal components from damage, prolonging lifespan and reducing maintenance and replacement costs. Overall, insulation quality significantly impacts power system stability and cost-effectiveness.

2. Limitations of Traditional Insulation Materials2.1 Fault Performance in High Voltage EnvironmentsTraditional materials struggle in high-voltage transformer environments. Defects such as impurities or air bubbles concentrate electric fields, causing breakdowns when voltage exceeds material tolerance. Breakdowns lead to internal short circuits, potentially causing fires or equipment failures. Partial discharge, though initially minor, gradually degrades insulation over time, compromising long-term reliability. These issues pose significant risks to power system safety and stability.

2.2 Performance Degradation at High TemperaturesTransformers generate heat during operation, accelerating degradation of traditional materials. Elevated temperatures reduce insulation resistance, increasing leakage current and energy losses. For solid insulations like oil-paper, thermal decomposition and degradation occur, worsening insulation properties. Oil insulation, though maintainable through oil replacement, still faces accelerated aging from heat, leading to cellulose degradation, moisture generation, and oxidation reactions. These problems not only impair transformer performance but also shorten lifespan and increase maintenance costs.
