摘要
针对一起220 kV变压器事故进行了理论分析,经现场检查与返厂解体检查发现故障原因为变压器生产工艺不良导致变压器内部悬浮放电,避免了事故的进一步发展,为今后220 kV变压器安全运行和技术监督积累了经验。
The 220 kV transformer accident is analyzed in theory, the cause of which is found by on-site inspection and returned dis- integration. Transformer internal suspended discharge is caused by the production process failure and further damage is avoided. The experience for the safe operation and technical supervision of the 220 kV transformers is accumulated.
