摘　　要：山火燃烧形成的导电物质，在导线与地面间产生大量电荷，造成导线对地放电；烟雾使得输电线路之间发生空气间隙被击穿，导致线路跳闸或停运事故。针对山火导致输电线路跳闸故障多发且防治困难的问题，基于无线传感器网络技术，选取变电站周围3个塔架，安装三套山火监测设备，对变电站周围的烟雾、温湿度、CO和H2S进行实时监测，系统实现了对变电站周围的火情发现和输电线路运行的火险警告。监测结果表明：在4月23号～6月16号期间，温度的变化范围为10-35℃，湿度的变化范围为20％-80％RH，CO的变化范围为（0—7）×10-6，H2S为0。系统运行至今，成功监测变电站周围两次森林火灾。The colaductive material formed by forest fires produce a large amount of electric charge between conductor and ground, which will lead to discharge;air space between transmission lines breakdowns because of smog,which will lead to line tripping or railway accident. Aiming at problem of frequent line tripping because of forest fires and difficulty in preventing, based on wireless sensor networks （ WSNs ） technology, three towers are selected around substation, and every tower is installed with one set of fire monitoring equipment. Those equipments can real-time monitor smoke, CO, H2S, temperature and humidity around the substation. This system realizes detection of fire around the substation and fire warning of transmission lines. Monitoring results show that on April 23 - June 16, temperature changes at range of 10 -35 ℃, humidity change at range of 20 %- 80 % RH, the change of CO range of （ 0 - 7 ） × 10-6, H2S to 0. So far, the system has monitored two forest fires around substation.
