国产小体积SDVL-HS系列压敏电阻器具有优异限压比,为基站电源等户外设备提供雷电防护
雷电是自然界中正常的放电现象,在雷击点的周围空间内会产生强大的交变电磁波向外发散式的传播,处于其中的带电导线或电路上均产生感应过电压。随着科技化进程的越来越快,电子设备越来越多,雷击事故带来的损失和影响也越来越大,尤其在防雷措施还不够完善的区域或者设备,雷击造成电子设备的损坏,给人们的财产以及公共设施财产造成巨大损失。
雷击感应引起的电磁脉冲,开路电压和短路电流仅是同一现象的两个不同方面,在真实电磁脉冲环境中,如果设备负载发生变化,从高阻抗变为低阻抗时,原来的冲击电压立即转化为冲击电流,亦即冲击电压和冲击电流是一个事物的不同表现方式而已,相互之间会通过设备负载情况而相互转化,因此IEC60060-1标准中规定的雷击浪涌测试波形主要有:8/20μs&1.2/50μs(短路电流,开路电压组合波用于电力线端口和短距离信号线路)、5/320μs&10/700μs(短路电流,开路电压组合波用于对称通信线路),以满足设备不同负载下的雷击浪涌测试。冲击波用两数值的组合T1/T2来表示,T1表示波前时间,T2表示半峰值时间(从波头始点到波尾降至50%峰值的时间),时间单位均为μs,记作T1/T2,符号“/”无数学意义。浪涌冲击电流的波前时间T1定义为10%峰值和90%峰值两点之间所对应时间间隔T的1.25倍,浪涌冲击电压的波前时间T1定义为30%峰值和90%峰值两点之间所对应时间间隔T的1.67倍。

一、压敏电阻器是什么?
压敏电阻器的电阻值随着外加电压变化而变化,属于半导体陶瓷元件,压敏的主要成分为氧化锌,通过混合多种金属氧化物高温烧结而成。压敏在预击穿区时,施加在压敏两端的电压小于压敏电压,这时候的压敏不工作,相当于一个兆欧级别的电阻,而这时通过压敏的电流仅仅是μA级别,在电路中等于开路。在击穿区时,压敏两端的电压大于压敏电压时,这时的压敏内部的通过的电流急剧变化,然后通过接地泄放过电压引起的浪涌能量。后续压敏又会继续恢复兆欧级别的高阻态,不影响电路的正常工作。

1、产品特征
SMD结构,体积小,适合高密度安装,工作温度范围广,高能型,抗浪涌能力强,能承受很高的电压电流,极低的限压性能,可定制化。
2、应用领域
在基站电源,服务器电源,安防摄像头电源,智能电表和工业仪表盘等设备电源DC部分的雷电感应及浪涌过电压保护, SDVL-HS系列具有小体积,优异限压比,防护能力强等优点,非常适用于容易受到雷电感应过电压及浪涌过电压的户外设备进行防护。

2.1 应用注意事项
关于压敏的应用注意事项,需要关注三个主要参数
1)压敏电阻最大直流工作电压Umax不小于线路正常工作电压Un的(1.2~1.5)倍,即Umax≥1.2Un
2)压敏电阻限制电压( Ip处 )小于被保护元件或组件的承受电压
3)压敏电阻最大峰值电流Ip大于DC-DC中感性元件产生的脉冲电流峰值
特别注意:当电路中压敏的限制电压未达到后端IC防护的最高承受电压要求,可以通过和电阻电感组成L型防护或者π型防护搭配对后端电路进行二次防护,以达到过压防护的要求。
2.2 应用场景
在雷雨天气中,为防止基站设施被雷电感应到电路中的过电压损坏,对于交流配电箱等380V及以上高压配电空间较大的场合,对一级防护部件的耐压、耐久以及浪涌冲击强度都有着较高的要求,通常会采用专用的防雷器(SPD)来进行雷电防护,但是对于后端48V直流供电系统二级防护而言,有以下三种方案:
方案一:只用TVS防护,需要大尺寸的TVS来承受高浪涌电流,TVS防护成本高。
图7 基站电源防护电路
方案二:后端MOS的耐冲击电压低于压敏限制电压时,可用压敏进行前端一级限压,二级采用常规TVS进行二次限压,达到低残压保护后端MOS的目的,组合型防护成本中等。
图8 基站电源防护电路
方案三:后端MOS的耐冲击电压高于压敏限制电压时,只采用压敏进行防护即可,成本最低。
图9 基站电源防护电路
压敏电阻的防护能力:SDVL-HS系列压敏在很高的脉冲电流冲击下依旧能够很好的电压抑制能力,能有效的保护后端的电路,下图是5kA的8/20μs脉冲电流冲击下压敏SDVL5650SD650PTHS502的电压波形,在很短的时间内能有效的将电路中峰值电压10KV抑制到176V,测试设备的内阻为2Ω,对应的峰值电压为10KV。
