电力通信设施过电压防护的探讨

Discussion on Overvoltage Protection of Electric Power Communication Facilities

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 com-munication facilities, this paper introduces key points in inspection of overvoltage protection devices in elec-tric 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 e-quipotential connection in detail and discusses real time monitoring probability of SPD operative mode.
