摘要
某台220kV变压器发生故障后,为确定其故障类型及受损程度,文章首先对该变压器在发生故障前的事件经过进行了分析,然后通过对该变压器开展电气试验和油气试验,并将变压器返厂解体检查,判断该变压器故障为纵绝缘故障。最后,对变压器发生故障的原因进行了分析。
In order to determine the fault type and damage degree of a certain 220 kV transformer, the paper first analyzes the events before the fault, and then carries out electrical test and oil and gas test on the transformer. After the transformer is returned to the factory and disassembled, the fault of the transformer is judged to be a longitudinal insulation fault. Finally, the causes of transformer failure are analyzed.
