摘要
针对在运20年的发生绝缘故障的110kV变压器,在交流电场下利用高分辨率的空间电荷检测装置进行了故障诊断,并通过变压器解体检查验证了利用空间电荷检测技术进行油纸老化测量的可行性。
For the 110 kV transformer with insulation fault occurred after 20 years operation,the fault diagnosis is carried out by using high-resolution space charge detection device under AC electric field.The correctness of space charge detection results is verified by disassembly inspection.
