摘　　要：铁路电力系统沿线场站多处于无人区,场站内电力设备受运行年限、工作环境恶劣等因素影响,易发生火灾事故,但目前缺乏经济可靠的监测手段预警。对此,着重阐述火灾发生的三个阶段,针对每个阶段的非电气量特征值进行精准感知,提出高压场站火灾极早期预警技术,设计一种铁路沿线场站微区域环境异常温升极早期预警系统。该系统通过实时采集火灾各个阶段的热释粒子等信号,经分析处理后判定现场环境是否存在异常,及时发出报警信息。该系统可在火灾产生烟雾及明火前发出预警,充分保障场站的运行安全。Power stations along railways are mostly located in depopulated areas.Factors such as operating years and poor working environment make electrical equipment in railway power stations have high risk of fire accidents,and there currently lacks economic and reliable monitoring means of early warning these fires.This article focuses on three stages of fire occurrence,accurately perceiving the non-electrical characteristic values of each stage,proposing an extra-early warning technology for high-voltage station fires,and designing an extra-early warning system for abnormal temperature rise in the micro area of stations along the railway.The system collects signals such as heat released particles at each stage of the fire in real time,analyzes and processes them to determine whether there are abnormalities in the on-site environment,and promptly sends out alarm information.The system can give an early warning before a fire generates smoke and apparent flames,fully ensuring operational safety of power stations along railways.
