特高压直流换流变压器是换流站的核心设备之一,其健康状况关系着整个特高压直流换流站的安全稳定运行,在发现监测数据异常时需要对其进行快速、精准地局部检修与处缺。目前关于换流变压器高压套管底部接线端子的家族性缺陷频发,急需针对特高压换流变压器缺陷部位进行精准的局部检修。为保证其内部元件保持良好的绝缘状态,整个作业过程严禁内部元件暴露在油面以外,并且露空作业面油温必须保持在35℃以上。

UHV DC converter transformers are one of the core equipment of converter stations.Their health status is related to the safe and stable operation of the entire UHV DC converter stations.When abnormal monitoring data is found,it needs to be quickly and accurately localized.Overhaul and deficiencies.Recently,there have been frequent family defects in the bottom terminals of highvoltage bushings of converter transformers.There is an urgent need to carry out precise local repairs on the defects of UHV converter transformers.In order to ensure that the internal components maintain good insulation,the internal components are strictly prohibited from being exposed to the oil surface during the entire process.In addition,the oil temperature of the working surface must be kept above 35℃.
