ABSTRACT

As the key equipment of the power system, the power transformer undertakes the important responsibilities of power transmission and voltage change, and is an indispensable part of the power system. However, the insulating oil in the transformer oil is often polluted for various reasons, which leads to the decline of the insulation performance of the transformer, causing accidents, and finally paralyzing the power system and causing huge economic losses. Aiming at the suspended bubbles in transformer oil, this paper infers the source and mechanism of bubble generation through the analysis of bubble composition, and sorts out the influence and harm of bubble movement characteristics under multi-physics coupling on transformer operation. The purpose is to summarize the research status and scientific research achievements of the past ten years, and analyze the research plan, so as to achieve an in-depth analysis of the development status of the subject and put forward a reasonable prospect for the development prospect.
