摘　　要：介绍了一起500kV油浸式电抗器误发油位异常的信号的经过、原因分析和整改措施,查明在发生直流接地的情况下,由于油位计辅助开关结构与设计不符、油位计二次接线错误导致该电抗器误发油位异常信号,最后采取有效的整改措施,为处理电抗器(变压器)类似故障提供了一种借鉴。This article describes the signal passing,cause analysis and rectification measures of a 500kV oil immersed reactor with an error in oil level,and finds that the structure of the auxiliary switch of the oil level gauge does not match the design in the case of DC grounding.The wrong secondary wiring of the meter causes the reactor to mistakenly send an oil level error signal.Finally,effective rectification measures are taken to provide a reference for handling similar faults of the reactor(transformer).
