抽水蓄能电站油浸式主变压器灭火系统分析对比研究

Analysis and Comparison of Fire Extinguishing System for Oil Immersed Main Transformer in Pumped Storage Power Station

通过对比水喷雾灭火、细水喷雾灭火、气体灭火、泡沫水喷雾灭火以及排油注氮灭火方式在抽水蓄能电站油浸式主变压器灭火时的使用规范以及异同点,同时对比分析不同灭火方式的优缺点,从消防系统响应时间、储存运输的安全性、事故后清理效率、使用成本以及应对主变复燃情况下的二次处理等多维度进行分析,结合抽水蓄能电站主变布置的实际情况,给出抽水蓄能电站优选的消防灭火系统方案。

This paper compares the application specifications and similarities and differences of water spray fire extinguishing,fine water spray fire extinguishing,gas fire extinguishing,foam water spray fire extinguishing and oil discharge and nitrogen injection fire extinguishing methods in oil immersed main transformers of pumped storage power stations.At the same time,it compares and analyzes the advantages and disadvantages of different fire extinguishing methods,from multiple dimensions such as response time of the fire protection system,safety of storage and transportation,efficiency of post accident cleaning,usage cost,and secondary treatment in case of main transformer reignition.Finally,based on the actual layout of the main transformer in the pumped storage power station,the optimal fire extinguishing system scheme for the pumped storage power station is proposed.
