摘要
以一起330 k V主变压器铁心多点接地故障为例,通过红外技术、油色谱分析和铁心电流在线监测等诊断方法,分析了变压器铁心多点接地故障原因,提出处理方案和处理方法,并结合变压器实际运行情况,给出了变压器运行维护和故障处理建议。
Taking a fault that a 330 kV power transformer core was grounded at points as example, using diagnostic methods such as infra-red technology, oil chromatograph analysis and core current monitoring, this paper analyzes the cause for faults that power transformer is grounded at points and gives treatment method and the scheme. With consideration on the actual operation condition of the transformer, some advices on transformer maintenance are also given.
