Zusammenfassung:FIELD: electricity.SUBSTANCE: method for protection of oil-filled transformer from explosion lies in introduction of SF6 gas to oil filling the transformer tank and pumping of the received mixture of oil and SF6 gas from the upper part of the transformer tank to the lower part through external pipeline at a speed equal or exceeding the speed of free ascent of SF6 gas bubbles diluted in oil.EFFECT: improving protection. Способ защиты маслонаполненного трансформатора от взрыва, заключающийся в том, что вводят элегаз в масло, заполняющее бак трансформатора, и перекачивают полученную смесь масла и элегаза из верхней части бака трансформатора в нижнюю через наружный трубопровод со скоростью, равной или превышающей скорость свободного всплытия пузырьков элегаза, растворенных в масле.
