When ambient temperatures rise, the cooling challenges faced by transformers increase exponentially. According to IEEE Std C57.91-2011 (Transformer Lifecycle Standard), for every 6\u00b0C increase in winding temperature, the aging rate of insulation materials doubles, and the transformer\u2019s lifespan is halved. This phenomenon, known as the &#8220;Montsinger Rule,&#8221; is one of the fundamental principles of transformer thermal design.<\/p>\n<h4 style=\"padding-left: 40px;\"><strong>1.1 Excessive temperature rise in high-temperature<\/strong><\/h4>\n<p style=\"padding-left: 40px;\">Environments triggers a chain reaction:<i><\/i><\/p>\n<p style=\"padding-left: 80px;\"><strong><span style=\"color: #4874cb;\">(1) Accelerated aging of insulation materials:\u00a0<\/span><\/strong>Traditional insulation materials undergo chemical decomposition under sustained high temperatures, losing dielectric strength.<\/p>\n<p style=\"padding-left: 80px;\"><strong><span style=\"color: #4874cb;\">(2) Reduced efficiency:<\/span><\/strong>\u00a0Winding resistance increases with temperature (per IEC 60076-7), leading to higher copper losses and lower efficiency.<\/p>\n<p style=\"padding-left: 80px;\"><strong><span style=\"color: #4874cb;\">(3) Safety hazards:\u00a0<\/span><\/strong>In extreme cases, localized overheating or even fire accidents may occur.<\/p>\n<p style=\"padding-left: 40px;\">A 2022 report by the International Energy Agency (IEA) revealed that in tropical and desert climates, 37% of annual transformer failures are caused by temperature rise issues\u2014far higher than the 15% observed in temperate regions.
