摘要
为得到轨道电路设备在不同温度、湿度环境下的雷电冲击传递特性规律,搭建不同温度、湿度环境条件下开展雷电冲击响应特性测试的试验平台,开展轨道电路关键设备在不同温度、湿度环境下的共模、差模雷电响应特性试验。研究试验获得在不同温度/湿度情况下的雷电冲击传递特性规律,为优化轨道电路设备雷电防护设计提供参考。试验结果表明:随着环境温度升高,设备共模和差模雷电冲击响应峰值均呈现上升趋势;随着环境湿度升高,设备差模雷电冲击响应峰值呈现下降趋势,设备共模雷电冲击过电压基本不受环境湿度影响。
In order to obtain the lightning impact characteristics of track circuit equipment under different temperature and humidity conditions,the tests of common mode and differential mode lightning response characteristics are carried out on its key equipment under different conditions.The test results show that the ambient temperature is positively correlated with the peak value of common mode and differential mode lightning responses,while the ambient humidity is negatively correlated with the peak value of differential mode lightning responses and is basically not affected by the common mode lightning impulse overvoltage of equipment.
