摘要

为找到SFZ9-CY-20000/220型变压器运行中油位突然降低的原因

结合变压器油位监测系统原理进行了分析

并计算了变压器油体积随温度变化的情况

在变压器停运时进行了油位的确认和处理

认为吸湿器堵塞是造成变压器油位突然大范围降低的原因。

Abstract

The cause of a sudden oil level descending in SFZ9-CY-20000/220 transformer during operation is analyzed according to the principle of transformer oil level detection.The change of oil volume with temperature is calculated

and the oil level is measured after the transformer stops operation.The conclusion is that the transformer oil level descending is induced by moisture absorber jam.
