摘要
铁路计算机联锁系统在进行动态模拟雷击试验时,电源端口和采集驱动端口最容易出问题,主要原因是对试验方法以及采集和驱动电路工作原理的不了解;结合雷击试验标准的要求,分析计算机联锁系统采集和驱动电路的工作原理,详细介绍铁路计算机联锁系统电源端口和采集驱动端口的模拟雷击试验方法,并对试验过程中需要注意的问题及结果评定进行说明,为以后铁路计算机联锁系统的防雷设计提供参考依据。
In the dynamic simulation of lightning test,the power port and the acquisition and drive port of the railway computer interlocking system are most likely to be damaged.The main reason is the failure to understand the test method and acquisition and drive circuit working principle.This paper analyzes the working principle of the acquisition and driving circuit according to the requirements of test standards,introduces in detail the lightning test method for the power port and the acquisition and driving circuit and addresses the fundamentals of the test and test result assessment,which may provide some references for lightning protection design of railway computer interlocking system.
