在PoE供电的案例中,很多时候PD设备是处于室外环境,比如IP camera,功率AP等,PoE端口雷电防护措施是必须认真对待和设计的事项了。


背景和开发目的

PoE(Power over Ethernet)也称为以太网供电,是一种可以通过双绞线来传输电力到装置上的技术。以太网供电技术的出发点是让IP电话、路由器、网络摄像头等小型网络设备,可以直接从以太网双绞线获得电力,而无需单独铺设电力线,以简化系统布线,降低网络基础设施的建设成本。PoE的这些优点使其得到快速推广,如今在大部分的交换机,服务器等都集成PoE接口,其在通讯、物联网、安防等领域得到广泛应用。


PoE的具体规范和接线如下图,IEEE80 2.3af允许两种用法:

1. 如图1,应用空闲脚供电时4、5脚连接为正极,7、8脚连接为负极。

图1


2. 如图2,利用信号线(1、2、3、6)同时传递数据信号和48V的电源。应用数据脚供电时,将DC电源加在传输变压器的中点,在这种方式下线对1、2和线对3、6可以为任意极性。传输数据所用的芯线上同时传输直流电,其输电采用与以太网数据信号不同的频率,不影响数据的传输。

图2

按照IEC61000-4-5要求,端口PoE供电必须进行共模、差模雷电及浪涌防护,满足客户整机技术要求。


方案和特点

目前主要防雷器件有压敏电阻、TVS二极管气体放电管等,它们的特性如下:

其中的片式压敏电阻SDVL系列是顺络电子开发专门用于电源端浪涌防护的器件,相比目标TVS管,具有过流能力强、体积小、性价比高等优点。


具体方案

目前较为严格的雷电防护需求为:

(1)共模防护:10/700μS:4KV/100A(40Ω) or 8/20μS 700A

(2)差模防护:10/700μS:2KV/50A(40Ω) or 8/20μS 350A


推荐方案:如下图3当中的①和②分别是采用空闲线供电(①)和信号线供电(②)的两种PoE连接方式,推荐PSE和PD端分别进行雷电防护,PSE端可以根据实际情况进行雷电防护。

具体方案-方案B:



方案分析:

1. 共模防护:

(1)在满足PoE 线路雷电防护标准的条件下,压敏电阻相比气放管,具有更高的性价比,是电源线路雷电防护及电源线路浪涌防护的主要元件。而气放管是数据传输线路雷电及浪涌防护的主要元件。

(2)由于压敏电阻能够吸收并衰减脉冲电流的能量,脉冲能量在地线(PE)的产生的瞬态电位升高远低于气体放电管(气放管不能吸收并衰减脉冲能量),因此压敏电阻对IC 的瞬间反地线脉冲电压影响很小。

(3)气放管的启动电压太高,而且启动电压的差异较大,其对线路保护效果有一定的分散性和风险。


2. 差模防护:

(1)对于既定的电源线路,压敏电阻的最大脉冲电流远大于相应的TVS,为满足产品雷电标准要求,TVS的性能参数需要更高,方可满足测试标准,而大功率TVS 价格很高。

(2)若受保护IC 的耐受脉冲电压能力较差,则采用压敏电阻保护效果有时候不甚理想,可在压敏电阻前端线路加电阻或电感元件以改善;若改善不良,则选用适当的TVS(TVS 的最大限制电压较小)。


以上方案已经得到多家IP Camera 厂家的认证和采用。由于方案的实际防护效果和整机电路环境有较大关系,请整机厂商试用该方案时如有异常请与世强联系。
