油枕事故排油系统在柔性直流联接变压器中的应用研究

Application and Research on Oil Pillow Accident Drain System of Flexible DC Connection Transformer

以渝鄂柔性直流背靠背施州换流站为研究背景,介绍柔性直流联接变压器油枕事故排油系统的组成构架、控制流程,阐述油枕事故排油系统的工作原理,模拟换流变火灾事故,通过不同的启动方式分别验证事故排油系统动作的可靠性,最大程度降低火灾损失,为大型充油设备的火灾消防提供一定参考。

It takes the Yu-E flexible DC back-to-back Shizhou converter station as the research background,which introduce the composition framework and control process of the oil pillow accident drainage system of flexible DC connection transformer.It explains the working principle of the oil drain accident oil drainage system,simulating a commutative fire accident.It individually verifies the reliability of the operation of the accidental drainage system through different startup methods,minimizes the fire loss and improve the fire protection level of the transformer,which provides some reference for fire fighting of large oil filling equipment.
