Ushbu maqolada uch fazali ikki chulg‘amli moyli transformatorlarning issiqlik rejimi tahlil qilinib, ularni Python dasturi asosida modellashtirish usullari bayon etiladi.
Transformatorning issiqlik dinamikasiga ta’sir etuvchi asosiy omillar — yuklama rejimi, moyning konvektiv harakati, magnit o‘tkazgichdagi isroflar hamda izolyasiya materiallarining termo-fizik xususiyatlari o‘rganildi. Tadqiqotda analitik issiqlik hisoblari bilan bir qatorda Python muhitida sonli modellashtirish algoritmlari ishlab chiqildi. Olingan natijalar moyli transformatorlarning ishonchliligini oshirish, issiqlik jarayonlarini oldindan baholash hamda optimal sovitish tizimini tanlashda amaliy ahamiyatga ega.
