Abstract

The inevitable temperature rise phenomenon in electrical equipment during operation not only affects normal operation and service life but may also lead to safety accidents. To address this issue, this study focuses on the temperature rise of electrical equipment, aiming to thoroughly analyze its causes and propose effective solutions. By collecting and organizing actual operational data from various types of electrical equipment, a mathematical model is established using thermodynamic theory combined with finite element analysis methods to simulate the heat transfer process within the equipment, accurately predicting temperature rise under different operating conditions. The research reveals that the primary factors contributing to temperature rise are insulation material aging, inadequate ventilation and cooling, and excessive load. Based on these findings, a comprehensive solution is proposed, encompassing optimized structural design, improved cooling methods, and reasonable load control. Innovatively, phase-change materials are introduced to enhance cooling efficiency, and an intelligent temperature control system is developed for real-time monitoring and automatic adjustment of equipment temperature. These measures effectively reduce the temperature rise amplitude of electrical equipment, improving safety and reliability while extending service life. This study provides theoretical support and technical guidance for the safe and stable operation of electrical equipment, offering significant engineering application value.
