摘要(Abstract)：
主变冷却系统的正常工作是主变安全运行的保证。在高温和重负荷下,尤其要加强对主变冷却系统的巡视,通过指示灯、表计和观察风扇、油泵的运转来综合判断,及时发现存在的问题。根据巡视中发现的500 kV主变B相油泵停止运转这一现象,详细介绍了其分析与处理的过程,最后提出了主变冷却系统巡视的要点。
The normal operation of the cooling system for the main transformer ensures the safe operation of the main transformer.Especially under high temperature and heavy load conditions,it is required to strengthen patrolling the cooling system together with comprehensive diagnosis through indicator lights,meters and observing the operation of the fans and oil pumps to identify problems in time.Based on the outage of Phase B oil pump of 500 kV main transformer found during patrol,this paper introduces the process of the analysis and treatment in detail and puts forward the key points of patrolling the cooling system.
