特高压换流站换流变水喷雾灭火系统动作可靠性的研究

Study on the operation Reliability of the Converter Variable Water Spray Fire Extinguishing System in the UHV Converter Station

通过对换流变水喷雾灭火系统动作可靠性的分析,提出减少水喷雾灭火系统误动的措施,避免因水喷雾系统误动导致换流变外绝缘闪络或非电量保护受潮引起的跳闸事故。

Based on the analysis of the operational reliability of the converter transformer water spray fire extinguishing system,measures to reduce the malfunction of the water spray fire extinguishing system are proposed to avoid the flashover of the inverter transformer’s external insulation or non-electrical protection due to the malfunction of the water spray system.Trip accident.
