摘　　要：随着变压器工艺的不断进步,变压器的重量不断增加,额定电压逐步提高,容量持续扩大,这给现场安装及试验,特别是局部放电(ACLD)试验提出了更高的要求。介绍了特大型变压器的典型结构,给出了进行现场ACLD试验的设备配置;分析了ACLD试验中变压器故障的发现过程及验证结果,证明了这套试验设备在现场进行特大型变压器ACLD试验的可行性。With the progress of transformer technique, weight of transformer is increased, the rated voltage is raised and the capacity is enlarged, which puts up higher requirement on field installation and test, especial-ly on partial discharge test. The paper introduces typical structure of oversize transformer and gives equipment configuration for field partial discharge test; it analyzes detection and validation of transformer failure and demonstrates that the test equipment is feasible in field partial discharge test of oversize transformers.
