上道通信信号设备的雷击试验

Lightning Test for Communication and Signal Equipment Installed on Railway Tracks

为了保证综合防雷系统安装的SPD与通信信号设备端口的耐雷电水平协调配合,厂家必须提供设备端口的额定冲击耐受电压水平Uw的数据,因此必须对通信信号设备进行雷击试验。阐述了通信信号设备雷击试验的范围、试验波形的选取、试验法和合格判定标准,并提出加速编制通信信号设备雷击试验的标准。

In order to ensure the coordination of lightning resistant capabilities between SPD installed in an integrated lightning protection system and the communication and signal equipment ports,the manufacturers should provide the rated impulse withstand voltage level Uw data of their equipment ports.So,lightning tests on communication and signal equipment must be carried out.This paper describes the scope of lightning test,the selection of test waveforms,testing method and conformity criteria of communication and signal equipment and proposes to accelerate the establishment of lightning test standards of communication and signal equipment.
