Transformateur de surchauffe co\u00fbts industries mondiales de plus de 12 milliards de dollars par an. Selon la Commission \u00c9lectrotechnique Internationale (CEI), le d\u00e9passement de la temp\u00e9rature nominale de 8\u00b0C coupes transformateur de la dur\u00e9e de vie de 50%. Le Minist\u00e8re chinois de l'Industrie et de la Technologie de l'Information a appliqu\u00e9 des strictes limites de temp\u00e9rature (par exemple, l'enroulement \u226498\u00b0C) dans son Transformateur Plan d'Efficacit\u00e9 \u00c9nerg\u00e9tique (2023-2025). Cet article combine la norme IEEE C57.91 vieillissement thermique mod\u00e8le et mondial des \u00e9tudes de cas pour expliquer comment la surchauffe dommages transformateurs et met en \u00e9vidence le co\u00fbt des strat\u00e9gies d'\u00e9conomie par le biais de smart technologies de refroidissement.<\/p>\n

La temp\u00e9rature acc\u00e9l\u00e8re la d\u00e9t\u00e9rioration de l'isolation. Par exemple, tous les 6\u00b0C r\u00e9duit la dur\u00e9e de vie de la Classe, Une isolation (par exemple, la r\u00e9sine \u00e9poxy) de 50%.
