Abstract

연속 액상인 전기절연유에 분산상인 기상(공기)이 주입되는 기-액상 회분식 기포탑을 이용하여 절연유 중에 용해되어 있는 용존가스의 추출특성을 고찰하였다. 기포탑의 자유공간과 유(油)의 체적비, 기상유속, 추출시간, 액상점도 등의 주요 실험변수가 절연유 중 용존 추출가스 농도에 미치는 영향을 실험을 통하여 고찰하였다. 실험결과는 용존가스의 종류와 양을 매우 효율적으로 측정할 수 있는 기술을 제시할 수 있어서 기포탑 추출기의 설계뿐 아니라 효과적인 변압기 예방진단기술을 확립하는 데 중요한 정보를 제공할 수 있을 것으로 사료된다.

Extraction characteristics of gases dissolved in insulating oil have been investigated in a batch type bubble column. Effects of the volume ratio of insulating oil to freeboard in the bubble column, gas velocity, liquid viscosity and bubbling time on the concentraction of gases extracted from the insulating oil have been determined. The results can be utilized to obtain the important informations on the design of bubble column extractor as well as the development of fault diagnosis technology for the electric transformers.
