±800 kV特高压换流变压器CAFS自动控制系统设计研究

Design and Research on CAFS Automatic Control System for±800 kV UHV Converter Transformer

固定式压缩空气泡沫灭火系统(CAFS)不仅具有灭火能力强、速度快、灭火效率高、安全可靠等特点,且经过试验验证,可用于扑救换流变压器等油类火灾。将其首次应用到国内某±800 kV换流站工程,阐述了压缩空气泡沫系统控制系统的结构、配置和功能,给出了站内设备布置和火灾报警系统接口等设计要点。对后续特高压工程压缩空气泡沫灭火控制系统设计具有借鉴作用。

The compressed air foam system(CAFS)has the characteristics of strong fire extinguishing ability,fast speed,high fire extinguishing efficiency,safety and reliability.It has been tested and verified that can be used to extinguish oil fires such as converter transformers.The CAFS was applied to a domestic±800 kV converter station project for the first time.The paper mainly introduces the structure,configuration,function,and equipment layout of theautomatic control system of the CAFS.It can be used as a reference for the design of the CAFS in the following ultra-high vottage(UHV)engineering.
