摘　　要：直流电源上的暂态过电压(TOV)是造成直流通信设备损坏的重要原因之一,但目前对直流电源暂态过电压机理和测试的研究较少。根据实际通信站点的工况,分析研究了真实场地、实验室模拟场地及实验室简易模拟等三种直流电源TOV的试验方法。为直流电源TOV机理的研究提供了试验手段,为直流电源TOV的防护设计提供了数据支撑和验证方法。在国内某真型试验场地进行的通信站点某典型场景的直流电源TOV试验复现了现场故障,验证了直流电源TOV产生的原理和路径、暂态过电压造成直流通信设备损坏的机理。The power frequency transient overvoltage(TOV)on the DC power supply is one of the important causes for the damage to the DC communication equipment.However,the mechanism and test of the power frequency transient overvoltage on the DC power supply are rarely studied.According to the working condition of the actual communication site,the test methods of three kinds of TOV of DC power supply are analyzed and studied,such as real site,simulated real site and simple simulated lab.It provides test means for the research of the mechanism of the DC power supply TOV,and provides data support and verification methods for the protection of the DC power supply TOV.In addition,a DC TOV test in a typical condition of a communication site was performed in a real test site in China.Through the test,the same fault as that in the field was reproduced,and the principle and path of DC power TOV generation and the mechanism of DC communication equipment damage caused by transient overvoltage were verified.
