摘要（英）：

The invention discloses a bubble suppression method and device of a large-scale transformer during live-line oil filtering. The device comprises a transformer live-line oil filtering device and a live-line oil filtering unit, wherein a vacuum bubble elimination device and a forced bubble removal device are connected in series in the transformer live-line oil filtering device, the vacuum bubble elimination device adopts a vacuum pump to vacuumize a vacuum pot, the vacuum degree reaches 5-150Pa, and the flow rate of transformer oil is controlled to be 30-150L/min. By the device, the safety risk of bubbles to transformer running during live-line oil filtering of the large-scale transformer can be effectively avoided, and the product production is very convenient to achieve; and with the adoption of the bubble suppression method and device of the large-scale transformer during live-line oil filtering, the live-line oil filtering unit is improved, live-line oil filtering operation in a transformer site is safely and efficiently facilitated, and thus, the device has potential and expected economic benefit.
