摘要
变压器有载调压分接开关(以下简称分接开关)是变压器在不停电的情况下完成输出电压调节的核心组件.近年来,真空有载调压分接开关在电网企业中开始运用.真空有载分接开关的绝缘油检测是确保其安全稳定运行的重要手段.本文通过对某局110 kV以上的45台主变中真空有载调压分接开关的绝缘油检测与分析的实践,提出与之相关的运维建议.
Abstract
The transformer on-load tap changer(hereinafter referred to as the tap changer)is the core component of the transformer to complete the output voltage regulation without power failure.In recent years,vacuum on-load tap changers have been used in power grid companies.The insulation oil detection of vacuum on-load tap changers is an important means to ensure its safe and stable operation.In this paper,through the practice of testing and analyzing the insulating oil of the vacuum on-load tap-changer in 45 main transformers above 110 kV in a certain bureau,the relevant operation and maintenance suggestions are put forward.
