水电站主变事故排油系统的典型设计

Typical Design of the Accidental Oil Discharge System of the Main Transformer of a Hydropower Station

油浸式电力变压器是水电站中常见的一次设备,变压器在发生事故时,可能会出现绝缘油泄漏的情况,造成环境污染并引发火灾。文章以已建、在建水电站为例,详细介绍了水电站主变事故排油系统的2种典型设计方案,为其它水电站主变事故排油系统的设计提供参考。

Oil-immersed power transformers are common primary equipment in hydropower stations.In the event of transformer accident,insulating oil may leak,causing environmental pollution and fire.Taking the hydropower stations that have been built or under construction as examples,the article introduces in detail two typical design schemes of the accidental oil discharge system of the main transformer of hydropower station,which provides references for the design of the accidental oil discharge system of the main transformer of other hydropower stations.
