摘要
针对某电厂#2机组主变压器在首次空载合闸时箱沿短接排发生明显放电现象,阐述了放电缺陷的紧急处理过程,分析了放电原因,并评估了本次放电对变压器后续运行可能产生的影响。
The main transformer of Unit 2 of a power plant has obvious discharging phenomena at the short junction of the box edge during the first no-load closing. This paper mainly expounds the emergency treatment of discharge defects, analyzes discharge causes, and assesses the possible impact of this discharge on the subsequent operation of transformers.
