变压器有载调压开关热缺陷故障的处理方法

Treatment of Thermal Defect Fault of On-load Voltage Regulating Switch of Transformer

变压器有载调压开关作为变压器中调压功能核心部件,一旦发生故障,将威胁变压器供电安全。在变压器运行过程中,需将有载调压开关作为重点检修对象,对调压开关的机械性能类故障进行分析。

The transformer on load tap changer is the core component of voltage regulating function in transformer.Once it fails,it will threaten the safety of transformer power supply.In the process of transformer operation,it is necessary to take on-load voltage regulator switch as the key maintenance object,and analyze the mechanical performance fault of voltage regulator switch.
