摘要(Abstract):
结合电力通信设施运维的实践经验,介绍了电力通信设施过电压防护装置的检查要点,分析了电涌保护器SPD引线长度对过电压防护的影响、接地及等电位连接等电力通信设施过电压防护的常见问题,探讨了实时监控SPD工作状态的可能性。
In combination with the practical experience in operation and maintenance of electric power communication facilities, this paper introduces key points in inspection of overvoltage protection devices in electric power communication facilities; it analyzes common overvoltage protection problems in electric power communication facilities such as the influence of surge protector lead wire on overvoltage, grounding and equipotential connection in detail and discusses real time monitoring probability of SPD operative mode.
