通信电源系统是对通信局站各种通信设备及建筑负荷等提供用电的设备和系统的总称。主要由备用发电系统、高压供电系统、变压器系统、不间断电源系统、后备电源系统、直流系统、接地防雷系统以及动力环境监控系统等多个子系统组成。通信离不开电源,通信电源是通信的保障,所以保证通信电源系统的安全运行,对保证通信系统的畅通乃至通信的安全有着积极的意义。
1 加强通信设备的过电压防护
以大规模集成电路为核心的通信设备随着信息科学技术的发展而得到广泛应用,比分立元器件设备体积小、运行速度快、功耗小、故障率低、便于维护管理是其显著的优点。但它绝缘强度低,工作电压低,承受过电压能力弱,是属于低电平、微电流系列的电子设备。当受到电网过电压或雷电干扰时,电子通讯设备往往会受到较大的破坏。据有关研究显示,过电压对电子通信设备造成的故障损坏比重占到总事故的三至四成。因此加强通信设备的过电压防护,降低设备故障率,已经成为通信维修工作的重中之重。
1.1 加强电源设备的雷电过电压防护
电源是通信设备安全运行的基础,一个良好的电源系统,为通信设备的安全运行提供了坚实的基础。首先要消除由于雷电干扰引起的过电压对通信电源的不良影响。信息产业部发布了专门的通信电源防雷标准,对各种通信站的电源防雷提出了具体要求,主要是两条:一是电力电缆应有金属屏蔽层,且必须埋地进出通信站。其次是在电源上逐级全面加装电源防雷器,实现多等级防护。即在变压器的低压侧加装低压防雷器,高压端加装高压防雷器,在直流配电屏和交流配电屏分别加装直、交流防雷器。防雷设计是保证通信电源系统可靠运行的不可缺少的环节,雷电对信息设备产生危害的根本原因在于雷电电磁脉冲,这种雷电电磁脉冲包括雷电流和雷电电磁场。产生过电压的根源是雷电流,而雷电电磁场则是产生感应过电压的根源。对于通信设备来说,雷电过电压来源主要包括直击雷/感应雷过电压、雷电侵入波和反击过电压。在一般情况下,通信电源必须采取概率防护、系统防护和多级防护的防雷原则,通信电源系统应采用多级防雷体系。而采用防雷器件时还应该考虑到防雷器件对系统的影响,包括工工作电流、作电压、工作频率、谐波干扰、工作温度、绝缘等级、泄漏电流、插入损耗、结构形式、远程监控、操作与维护等,还有安规的影响等。
1.2 通信线路防止过电压
各种通信设备的入口和出口,必须通过通信电缆才能与用户发生联系,而设置保安配线柜(架) 则就是为方便安全配线。有的公司只用一个分线箱就进行出线、入线的汇接而没有安装保安配线柜(架),这种做法极易造成通信设备的损坏。通信的特点是可靠性高、容量小,通信电缆沿电力杆路架设强电、故受强电磁场干扰的概率大。特别是在住宅区,电话线沿电力杆路与照明线同杆架设和通信音频电缆,交叉处的绝缘层发生损坏,导致强电侵入。吊挂通信电缆的钢绞线,由于城区地形不一、一些照明线、灯箱线交错,容易引起强电侵入或干扰。雷电干扰或是一些线路故障、产生电流突变时,会产生瞬变强电磁场,从而造成对通信线路的强电磁感应过电压。有时会产生程控电话交换机大面积烧坏、停运的故障,因此,通信电缆进入机房务必得接入保安配线柜。保安配线柜应装有抑制电缆线对纵向对过电压、过电流的限幅装置。 压敏电阻或固体(气体)放电管与正温度系数热敏电阻,组成抑制过电压能力强,响应速度快,通流量大的保安单元。当一些通信线路与电力线接触时或遭受到雷电干扰,固体(气体)放电管放电(或压敏电阻限幅)将高压入地,使危险电压下降到安全范围。如线路遭受幅值在350ma以上电流时,正温度系数热敏电阻的阻值会迅速增加,使线路呈现断开状态,回路电流幅度减小,从而保护了室内通信设备。当过过电流、电压消除后,保安单元就会自动恢复正常。所以,保安配线柜的使用对于防止通信线路干扰过电压,降低设备故障率是非常必要的。
1.2 communication lines to prevent overvoltage
the entrance and exit of all kinds of communication equipment must be connected with the user through the communication cable, and the security wiring cabinet (frame) is to facilitate the safety wiring. some companies use only one branch box to go out and connect to the line without installing a security wiring cabinet (frame), which is very easy to cause damage to the communication equipment. communication is characterized by high reliability and small capacity, and the probability of strong interference caused by strong electric magnetic field is strong for communication cables to be erected along the power poles. especially in the residential area, the telephone line is erected along the pole road and the lighting line to set up and communicate audio cables. the insulation layer at the intersection is damaged, which leads to strong electricity invasion. because of the different terrain of the city, the interlacing of some lighting lines and light boxes, it is easy to cause strong electricity intrusion or interference. when lightning interference or some line faults occur and sudden changes in current occur, a transient strong magnetic field will be generated, resulting in strong electromagnetic induction overvoltage on communication lines. sometimes there will be trouble of large scale burn out and shutdown of program-controlled telephone exchanges. therefore, communication cables must be connected to the security distribution cabinets when they enter the computer room. the security wiring cabinet shall be equipped with a limiting device for restraining the longitudinal overvoltage and overcurrent of the cable. a pressure sensitive resistor or a solid (gas) discharge tube and a positive temperature coefficient thermistor to form a security unit with strong ability to suppress overvoltage, fast response and large flow rate. when some communication lines contact with the power line or suff中兴zxdu68 t601高频开关电源机柜er from lightning interference, the solid (gas) discharge tube (or pressure sensitive resistance limit) puts the high pressure into the ground and reduces the dangerous voltage to the safety range. if the line suffers from a current of more than 350ma, the resistance value of the positive temperature coefficient thermistor will increase rapidly, making the line disconnected and reducing the loop current amplitude, thus protecting the indoor communication equipment. after overcurrent and voltage are eliminated, the security unit will automatically return to normal. therefore, the use of security distribution cabinets is necessary to prevent communication lines from disturbing the overvoltage and reducing the failure rate of equipment.
