摘　　要：局部放电试验可有效检测220 kV变压器的隐蔽风险,为变压器安全可靠运行提供良好保障。以SSZ10-220系列变压器为例,设计局部放电试验方案,确定试验接线并计算合格判据。同时,针对现场干扰因素设计防护措施,保证220 kV变压器现场局放试验科学展开,从根本上提升试验的可靠性和有效性。The partial discharge test can effectively detect the hidden risks of 220 kV transformers,and provide a good guarantee for the safe and reliable operation of the transformers.Taking SSZ10-220 series transformers as an example,this study designs a partial discharge test scheme,determines the test wiring and calculates the qualification criteria.At the same time,protective measures are designed for on-site interference factors to ensure that the 220 kV transformer on-site partial discharge test is carried out scientifically,and the reliability and effectiveness of the test are fundamentally improved.
