【英文标准名称】: Resistibility requirements to overvoltages and overcurrents due to lightning for equipment having telecommunication ports 【原文标准名称】: 有通信站的设备耐受由放电火花引起的过电压和过电流的要求 【标准号】: BS EN 50468-2009 【标准状态】: 现行 【国别】: 英国 【发布日期】: 2009-07-31 【实施或试行日期】: 2009-07-31【发布单位】: 英国标准学会(GB-BSI)【起草单位】: BSI【标准类型】: ()【标准水平】: ()【中文主题词】: 通信连接;通信设备;通信网;通信;定义(术语);电气工程;电阻率;抗扰度;抗干扰度;干扰(波物理学);闪电;避雷装置;过电流;过电流保护;过电压;过电压保护装置;耐力;抗破坏性;电信;电信系统;电讯;终端【英文主题词】: Communication connections;Communication equipment;Communication networks;Communications;Definitions;Electrical engineering;Electrical resistivity;Immunity;Interference rejections;Interference (wave physics);Lightning;Lightning protection;Overcurrent;Overcurrent protection;Overvoltage;Overvoltage protection;Resistance;Resistance to destruction;Telecommunication;Telecommunication systems;Telecommunications;Terminals【摘要】: This European Standard specifies the minimum level of resistibility of equipment havingtelecommunication port(s) to overvoltages and overcurrents.This European Standard covers telecommunication equipment installed at customer premises asshown in Figure 1.Overvoltages or overcurrents covered by this European Standard are surges due to direct or indirect lightning on the telecommunication line plant.Overvoltages or overcurrent not covered by this European Standard are– short-term induction of alternating voltages from electric power systems (including electrifiedrailway),– earth potential rise due to power faults or load switching,– direct contacts between telecommunication lines and low voltage power lines.This European Standard is intended for use by network (public/private) operators and the equipmentmanufacturers.This European Standard applies to equipment having telecommunication port(s) connected to externalconductors, i.e. conductor located outside the customer’s building.The tests are type tests and, although they are applicable to a complete system, it is recognised that they may be applied to individual items of equipment during development and design work.【中国标准分类号】: K09【国际标准分类号】: 29_120_50;91_120_40【页数】: 16P.;A4【正文语种】: 英语
